The preview uses the same HTML you see in the output card, but rendered into the live preview area as DOM. So what you see is what the browser will paint. The download button captures the HTML at the moment you click; copy captures the same. There is no debounce because the parser is fast enough that typing 80 wpm does not cause lag on a modern phone."},{"question":"Is my data private?","answer":"Yes. The parser is custom pure-JS inlined in the HTML. There are no network calls, no CDN scripts, no analytics. The Markdown is processed locally in the browser and never sent anywhere.

TIDAK didukung: nested fenced code, list bersarang lebih dari satu level, reference-style link ([text][ref]), footnote, task list (- [x]), strikethrough (~~text~~), HTML pass-through (HTML mentah di Markdown di-escape, tidak di-interpretasi), dan reference-style image. Parser sekitar 200 baris JS kustom yang di-inline di halaman."},{"question":"Kenapa pakai parser kustom dan bukan marked.js atau showdown?","answer":"Untuk menjaga tool tetap offline dan tanpa dependensi. Library Markdown populer (marked, showdown, markdown-it) sangat baik tapi butuh script CDN (panggilan jaringan) atau build step (npm + bundler). Parser in-house menangani 95% Markdown umum dalam sekitar 200 baris.

Kamu bisa mengunduh ini dan membukanya di browser mana pun dan akan render dengan benar. Ketika nonaktif, output hanya HTML bagian dalam (tag <h1>, <p>, dll. tanpa wrapper dokumen), cocok untuk ditempel ke halaman yang lebih besar atau field rich-text CMS."},{"question":"Bagaimana kerja pratinjau langsung?","answer":"Tiap ketukan di textarea Markdown memicu re-parse (sub-millisecond untuk dokumen tipikal) dan memperbarui baik kartu output HTML maupun kartu pratinjau yang di-render. Pratinjau menggunakan HTML yang sama dengan yang kamu lihat di kartu output, tapi di-render ke area pratinjau langsung sebagai DOM. Jadi yang kamu lihat adalah yang akan di-cat browser. Tombol unduh menangkap HTML pada saat kamu klik; salin menangkap yang sama. Tidak ada debounce karena parser cukup cepat sehingga mengetik 80 wpm tidak menyebabkan lag di HP modern."},{"question":"Apakah data saya privat?","answer":"Ya.

Binary is base 2 (each digit is 0 or 1) — the native format of computers. Hex is base 16 (digits 0-9, A-F) — the most common shorthand for binary because each hex digit represents 4 binary digits, so 4 bytes (32 bits) become 8 hex characters. Base32 is base 32 (alphabet A-Z and 2-7) — less compact than hex but case-insensitive and URL-safe, used in TOTP secrets and some file systems. Octal is base 8 (digits 0-7) — older Unix file permissions and some assembly languages. They are interchangeable representations; the tool lets you pick whichever is most convenient for the context."},{"question":"How does the UTF-8 handling work?","answer":"The tool operates on bytes, not characters. The encode step uses TextEncoder to convert the input string to a UTF-8 byte array, then formats each byte in the chosen representation. The decode step parses the encoded form back to a byte array, then uses TextDecoder with the fatal flag to convert bytes back to a string. If the byte array is not valid UTF-8, the decoder throws and the tool falls back to a lossy ASCII visualization (replacing each non-ASCII byte with a dot). This means emoji and accented characters round-trip cleanly in the encode/decode direction, but pasting random binary that is not UTF-8 will give you the lossy fallback."},{"question":"Why is Base32 padded with = signs?","answer":"Base32 represents bytes in 5-bit groups. The input byte count is rarely a multiple of 5, so the output is padded with = signs to make its length a multiple of 8 characters. This is the RFC 4648 standard. The decoder strips trailing = signs before processing, so you can paste Base32 with or without the padding. The alphabet is the standard A-Z, 2-7 (32 symbols), which is why Base32 is case-insensitive — the encoder emits uppercase by convention, but the decoder accepts both cases."},{"question":"What does the separator option do on the Decode tab?","answer":"By default the decoder strips all whitespace, so a hex string with spaces, a binary string with spaces, or an octal string with newlines all parse correctly. The separator field lets you declare a specific separator (e.g. a colon, a comma, or \"0x\") that you want preserved in the output display. The decoder itself does not care what separator you use; it just removes all non-hex/non-binary/non-octal characters before parsing. The field is mostly for documentation — paste your formatted input, see it parsed correctly."},{"question":"Is my data private?","answer":"Yes. The encoders and decoders are pure JavaScript implementations of the standard algorithms, inlined in the HTML. There are no network calls and no CDN. The text you encode or decode never leaves your device. You can convert sensitive strings (passwords, tokens, internal IDs) without any data being transmitted."}],"faq_id":[{"question":"Apa beda biner, hex, base32, dan oktal?","answer":"Keempatnya adalah sistem numeral posisional yang merepresentasikan byte yang sama. Biner adalah basis 2 (tiap digit 0 atau 1) — format asli komputer. Hex adalah basis 16 (digit 0-9, A-F) — singkatan paling umum untuk biner karena tiap digit hex merepresentasikan 4 digit biner, jadi 4 byte (32 bit) menjadi 8 karakter hex. Base32 adalah basis 32 (alfabet A-Z dan 2-7) — kurang ringkas dari hex tapi case-insensitive dan URL-safe, dipakai di secret TOTP dan beberapa file system. Oktal adalah basis 8 (digit 0-7) — permission file Unix lama dan beberapa bahasa assembly. Mereka adalah representasi yang dapat dipertukarkan; tool memungkinkan kamu pilih mana pun yang paling удобно untuk konteksnya."},{"question":"Bagaimana kerja penanganan UTF-8?","answer":"Tool beroperasi pada byte, bukan karakter. Langkah encode memakai TextEncoder untuk mengonversi string input ke array byte UTF-8, lalu memformat tiap byte dalam representasi yang dipilih. Langkah decode mem-parse bentuk ter-encode kembali ke array byte, lalu memakai TextDecoder dengan flag fatal untuk mengonversi byte kembali ke string. Kalau array byte bukan UTF-8 valid, decoder melempar error dan tool fallback ke visualisasi ASCII lossy (mengganti tiap byte non-ASCII dengan titik). Ini berarti emoji dan karakter aksen round-trip dengan bersih di arah encode/decode, tapi menempel biner acak yang bukan UTF-8 akan memberimu fallback lossy."},{"question":"Kenapa Base32 di-padding dengan tanda =?","answer":"Base32 merepresentasikan byte dalam grup 5-bit. Jumlah byte input jarang merupakan kelipatan 5, jadi output di-padding dengan tanda = untuk membuat panjangnya kelipatan 8 karakter. Ini standar RFC 4648. Decoder memotong tanda = di akhir sebelum memproses, jadi kamu bisa menempel Base32 dengan atau tanpa padding. Alfabetnya adalah standar A-Z, 2-7 (32 simbol), itulah kenapa Base32 case-insensitive — encoder emit huruf besar berdasarkan konvensi, tapi decoder menerima kedua kasus."},{"question":"Apa yang dilakukan opsi separator di tab Decode?","answer":"Secara default decoder menghapus semua whitespace, jadi string hex dengan spasi, string biner dengan spasi, atau string oktal dengan newline semua parse dengan benar. Field separator memungkinkan kamu mendeklarasikan separator spesifik (mis. titik dua, koma, atau \"0x\") yang ingin kamu pertahankan di tampilan output. Decoder sendiri tidak peduli separator apa yang kamu pakai; dia hanya menghapus semua karakter non-hex/non-biner/non-oktal sebelum parsing.

For each compounding period (monthly, quarterly, etc.) it adds the per-period contribution, then multiplies the new balance by (1 + annual_rate / periods_per_year). This handles arbitrary compounding frequencies correctly. The per-period contribution is (monthly_contribution × 12 / periods_per_year), so the total annual contribution matches your monthly input regardless of the compounding frequency. The \"Contribute at start of month\" toggle controls whether the contribution is added before or after the interest accrues in that period."},{"question":"What is the real (inflation-adjusted) value?","answer":"The real value is what your nominal future value would buy in today's prices, accounting for inflation. The formula is real = nominal / (1 + inflation_rate)^years. So if you end up with Rp 1 billion after 20 years and inflation was 3% per year, the real value is Rp 1B / 1.03^20 = Rp 554 million in today's money. This tells you whether your investment is actually growing in purchasing power or just keeping up with rising prices. A 6% return with 3% inflation is a real 3% return, which doubles purchasing power in ~24 years."},{"question":"How does the tax on gains work?","answer":"Tax is applied once at the end, on the total interest earned (not on each period). The tool sums all interest over the lifetime of the investment, multiplies by your tax rate, and shows the tax owed and the net after-tax value. This is a simplification — actual tax rules may tax gains annually, allow cost-basis adjustments, or apply different rates to different holding periods. Use the tool for planning scenarios, not for tax filing. The tax field is optional; set to 0% for tax-advantaged accounts (401k, Roth IRA, Indonesian Reksa Dana)."},{"question":"What is the difference between compound frequencies?","answer":"Compounding frequency controls how often interest is added to the balance. Monthly means interest is calculated 12 times per year, quarterly 4 times, semi-annually 2 times, annually once. More frequent compounding produces a slightly higher final value because interest earns interest sooner. For a 6% annual rate over 20 years on Rp 10M with no contributions: monthly compounding gives Rp 33.1M, quarterly gives Rp 32.9M, annual gives Rp 32.1M. The difference is small for low rates and short periods, larger for high rates over decades.

You can use the tool to plan your personal finances, model retirement scenarios, or estimate loan costs without any data being transmitted."}],"faq_id":[{"question":"Bagaimana bunga majemuk dihitung dengan setoran bulanan?","answer":"Tool menjalankan simulasi periode demi periode. Untuk tiap periode compounding (bulanan, kuartalan, dll.) ia menambah setoran per-periode, lalu mengalikan saldo baru dengan (1 + tarif_tahunan / periode_per_tahun). Ini menangani frekuensi compounding sembarang dengan benar. Setoran per-periode adalah (setoran_bulanan × 12 / periode_per_tahun), jadi total setoran tahunan cocok dengan input bulanan kamu terlepas dari frekuensi compounding. Toggle \"Setor di awal bulan\" mengontrol apakah setoran ditambahkan sebelum atau setelah bunga bertambah di periode itu."},{"question":"Apa itu nilai riil (adjusted inflasi)?","answer":"Nilai riil adalah apa yang bisa dibeli oleh nilai nominal masa depan kamu dalam harga hari ini, dengan memperhitungkan inflasi. Formulanya adalah real = nominal / (1 + tarif_inflasi)^tahun. Jadi kalau kamu berakhir dengan Rp 1 miliar setelah 20 tahun dan inflasi 3% per tahun, nilai riilnya adalah Rp 1M / 1.03^20 = Rp 554 juta dalam uang hari ini. Ini memberitahu kamu apakah investasimu benar-benar tumbuh dalam daya beli atau hanya mengikuti harga yang naik. Return 6% dengan inflasi 3% adalah return riil 3%, yang menggandakan daya beli dalam ~24 tahun."},{"question":"Bagaimana kerja pajak atas bunga?","answer":"Pajak diterapkan sekali di akhir, atas total bunga yang dihasilkan (bukan di tiap periode). Tool menjumlahkan semua bunga selama masa investasi, mengalikan dengan tarif pajak kamu, dan menampilkan pajak terutang dan nilai bersih setelah pajak. Ini adalah penyederhanaan — aturan pajak aktual mungkin memajaki gain tahunan, memperbolehkan penyesuaian cost-basis, atau menerapkan tarif berbeda untuk periode holding berbeda. Pakai tool untuk skenario perencanaan, bukan untuk filing pajak. Field pajak opsional; atur ke 0% untuk akun yang di-tax-advantage (401k, Roth IRA, Reksa Dana Indonesia)."},{"question":"Apa beda frekuensi compounding?","answer":"Frekuensi compounding mengontrol seberapa sering bunga ditambahkan ke saldo. Bulanan berarti bunga dihitung 12 kali per tahun, kuartalan 4 kali, semi-tahunan 2 kali, tahunan sekali. Compounding lebih sering menghasilkan nilai akhir sedikit lebih tinggi karena bunga menghasilkan bunga lebih cepat. Untuk tarif 6% tahunan selama 20 tahun pada Rp 10 juta tanpa setoran: compounding bulanan memberi Rp 33,1 juta, kuartalan memberi Rp 32,9 juta, tahunan memberi Rp 32,1 juta. Bedanya kecil untuk tarif rendah dan periode pendek, lebih besar untuk tarif tinggi selama dekade.

The point is that most people spend too much time in Q1 and Q3, reacting, and not enough in Q2, which prevents future Q1 fires."},{"question":"How does drag-and-drop work on mobile?","answer":"Native HTML5 drag-and-drop is a desktop API. On touch devices, the touch-and-hold pattern varies by browser. iOS Safari and Chrome mobile do not support HTML5 drag from JavaScript by default. The card has cursor: grab on desktop so mouse users get the standard grab cursor. If drag does not work on your mobile browser, use the import flow — delete the old card and add a new one in the target quadrant, or edit and copy/paste the title."},{"question":"Where are my tasks stored?","answer":"In your browser localStorage under the key \"eisenhower-tasks\". It is never uploaded anywhere — there is no fetch, no API call, no CDN. Tasks persist across page reloads on the same device and browser profile. To move tasks to another device, use the export button to download a JSON file, then the import button on the other device. To clear everything, use \"Clear all\" or clear your browser data for this site."},{"question":"How is \"overdue\" calculated?","answer":"A deadline string is treated as a date in your local timezone (e.g. \"2026-06-20\"). The tool compares the deadline to today (midnight, local time) on each render. A task is \"overdue\" if the deadline is strictly before today (red badge), \"today\" if equal (green badge), or \"in N days\" if after today. The label updates live each time you open or refresh the page. Tasks without a deadline have no badge and never show as overdue."},{"question":"Is my data private?","answer":"Yes. The matrix is pure client-side JavaScript inlined in the HTML. Tasks live in localStorage, the export/import uses a local file in your Downloads folder, and there is no network call. Other people cannot see your tasks unless you explicitly share the export JSON with them. You can use the tool to plan work, manage personal projects, or organize a team retrospective without any data being uploaded."}],"faq_id":[{"question":"Apa itu Matriks Eisenhower?","answer":"Framework prioritas yang dipopulerkan oleh Presiden Dwight Eisenhower. Ia menyortir tugas pada dua axis: mendesak vs. tidak mendesak, dan penting vs. tidak penting. Kuadran Q1 (mendesak DAN penting) adalah \"kerjakan sekarang\" — krisis, deadline, kebakaran. Q2 (penting, tidak mendesak) adalah \"jadwalkan\" — perencanaan jangka panjang, olahraga, pembangunan relasi. Q3 (mendesak, tidak penting) adalah \"delegasi\" — interupsi, darurat orang lain. Q4 (tidak keduanya) adalah \"hapus\" — pembuang waktu, pekerjaan sia-sia. Poinnya adalah kebanyakan orang menghabiskan terlalu banyak waktu di Q1 dan Q3, bereaksi, dan tidak cukup di Q2, yang mencegah kebakaran Q1 di masa depan."},{"question":"Bagaimana kerja drag-and-drop di mobile?","answer":"Native HTML5 drag-and-drop adalah API desktop. Di device touch, pola touch-and-hold bervariasi antar browser. iOS Safari dan Chrome mobile tidak mendukung HTML5 drag dari JavaScript secara default.

Untuk pindah tugas ke device lain, pakai tombol export untuk download file JSON, lalu tombol import di device lain. Untuk menghapus semuanya, pakai \"Hapus semua\" atau hapus data browser untuk situs ini."},{"question":"Bagaimana \"terlambat\" dihitung?","answer":"String deadline diperlakukan sebagai tanggal di timezone lokal kamu (mis. \"2026-06-20\"). Tool membandingkan deadline dengan hari ini (tengah malam, waktu lokal) di tiap render. Tugas dianggap \"terlambat\" kalau deadline strictly sebelum hari ini (badge merah), \"hari ini\" kalau sama (badge hijau), atau \"dalam N hari\" kalau setelah hari ini. Label update live tiap kali kamu membuka atau refresh halaman. Tugas tanpa deadline tidak punya badge dan tidak pernah menampilkan terlambat."},{"question":"Apakah data saya privat?","answer":"Ya. Matriks adalah JavaScript murni sisi client yang di-inline di HTML. Tugas tinggal di localStorage, export/import memakai file lokal di folder Downloads kamu, dan tidak ada panggilan jaringan.

The full table covers lowercase a-z, uppercase A-Z, digits 0-9, and common punctuation like parentheses, brackets, exclamation and question marks. After flipping, the result is character-reversed so the last character comes first, which is what your eye expects for upside-down text. Characters not in the table (emoji, CJK, accented Latin) pass through unchanged, so the output can look mixed."},{"question":"Is ROT13 a real cipher?","answer":"Yes, but a very weak one. ROT13 shifts each letter 13 positions in the alphabet — a becomes n, b becomes o, and so on. Because 13 is exactly half of 26, applying ROT13 twice returns the original (it is its own inverse). It is commonly used on Usenet and in puzzle contexts to hide spoilers, punchlines, or off-topic jokes from casual readers. It provides zero security — any 5-year-old with frequency analysis can break it. Do not use it for anything you actually need to keep secret; use AES or similar for that."},{"question":"What does \"process each line separately\" do?","answer":"It splits the input on newlines, applies the transformation to each line independently, and joins the results with newlines. Without it, the transform is applied to the whole input as a single string, which means reverse-lines would just reverse the line order (useful) but reverse-chars would also reverse the newlines (the entire text including line breaks becomes one reversed block). With \"separate\" on, you can ROT13 or flip each line individually — handy for batch processing a list of pre-formatted strings, CSV cells, or log lines."},{"question":"How does the swap button work?","answer":"Swap moves the current output to the input box and the previous input to the output box, then re-runs the transformation. The counts and toast update. Use it to chain transforms: reverse chars → swap → ROT13 → swap → reverse words. Or to keep applying different transforms iteratively to the same source text. The state is not saved across page reloads — the input and output revert to whatever you last typed in the input field, and output regenerates on the next render."},{"question":"Is my text private?","answer":"Yes. All six transforms are pure string functions inlined in the HTML. There are no network calls, no API lookups, no CDN scripts. The Unicode flip table is a static object literal in the source.

Tabel lengkap mencakup a-z huruf kecil, A-Z huruf besar, digit 0-9, dan tanda baca umum seperti kurung, bracket, tanda seru dan tanya. Setelah flipping, hasilnya di-reverse karakternya supaya karakter terakhir jadi pertama, yang diharapkan mata untuk teks upside-down.

ROT13 menggeser tiap huruf 13 posisi dalam alfabet — a menjadi n, b menjadi o, dan seterusnya. Karena 13 persis setengah dari 26, menerapkan ROT13 dua kali mengembalikan asli (ia inversi sendiri). Umumnya dipakai di Usenet dan dalam konteks puzzle untuk menyembunyikan spoiler, punchline, atau jokes off-topic dari pembaca kasual. Memberi keamanan nol — siapa pun dengan frequency analysis bisa memecahkannya. Jangan pakai untuk apa pun yang benar-benar perlu kamu rahasiakan; pakai AES atau semacamnya untuk itu."},{"question":"Apa yang dilakukan \"proses tiap baris terpisah\"?","answer":"Ia memisahkan input pada newline, menerapkan transformasi ke tiap baris secara independen, dan menggabungkan hasil dengan newline. Tanpanya, transform diterapkan ke seluruh input sebagai string tunggal, yang berarti reverse-karakter juga akan me-reverse newline (seluruh teks termasuk line break menjadi satu blok terbalik). Dengan \"terpisah\" aktif, kamu bisa ROT13 atau flip tiap baris secara individual — berguna untuk pemrosesan batch daftar string terformat, sel CSV, atau baris log."},{"question":"Bagaimana kerja tombol swap?","answer":"Swap memindahkan output saat ini ke kotak input dan input sebelumnya ke kotak output, lalu menjalankan ulang transformasi.

It does not change path data, colors, or transforms. The one option with a visible effect is \"Round decimals (2)\" which truncates coordinate precision — for most icons and logos 2 decimal places is more than enough (the difference is sub-pixel), but for extremely large or high-resolution SVGs you may want to keep 3 or 4 decimals to avoid precision artifacts."},{"question":"Why are unused IDs removed?","answer":"Many design tools (Figma, Illustrator, Sketch, Inkscape) auto-generate id=\"layer_42\" type attributes for every shape, even when nothing references them. Keeping them just inflates the file. The tool scans for url(#id), xlink:href=\"#id\", and href=\"#id\" references and removes any id attribute that is not referenced. Be careful: if you embed the SVG inline in HTML and use CSS like #my-logo { ... } to style it from outside, that id WILL be referenced (via the CSS selector) but the optimizer cannot see that. In that case, turn off \"Strip unused IDs\"."},{"question":"Does this support SVGs with embedded styles or scripts?","answer":"It removes <style> blocks only via the metadata strip if you have it on — and only if the style tag is wrapped in <metadata>. Inline style attributes (style=\"fill:red\") are kept. <script> blocks are kept as-is. If your SVG has animation (<animate>, <animateTransform>, <animateMotion>) those are kept too, and the optimizer will not touch their attribute values.

If the source has viewBox=\"0 0 24 24\" and width=\"24\" height=\"24\", the preview shows it scaled to fit 160x160. If the source has no width/height, the optimizer does not add them — the browser will fall back to the viewBox or to 300x150 default. The viewBox is read from the source and shown in the card title as \"viewBox: 0 0 X Y\" so you can verify the optimizer did not mangle the coordinate system."},{"question":"Is my SVG private?","answer":"Yes.

Satu-satunya opsi dengan efek terlihat adalah \"Bulatkan desimal (2)\" yang memotong presisi koordinat — untuk kebanyakan icon dan logo 2 tempat desimal sudah lebih dari cukup (bedanya sub-pixel), tapi untuk SVG yang sangat besar atau resolusi tinggi kamu mungkin ingin mempertahankan 3 atau 4 desimal untuk menghindari artefak presisi."},{"question":"Kenapa ID tak terpakai dihapus?","answer":"Banyak tool desain (Figma, Illustrator, Sketch, Inkscape) auto-generate atribut id=\"layer_42\" untuk tiap shape, bahkan ketika tidak ada yang mereferensikannya. Mempertahankan mereka hanya membengkakkan file. Tool memindai referensi url(#id), xlink:href=\"#id\", dan href=\"#id\" dan menghapus atribut id apa pun yang tidak direferensikan. Hati-hati: kalau kamu embed SVG inline di HTML dan memakai CSS seperti #my-logo { ... } untuk men-style-nya dari luar, id itu AKAN direferensikan (via selector CSS) tapi optimizer tidak bisa melihat itu. Dalam kasus itu, matikan \"Hapus ID tak terpakai\"."},{"question":"Apakah ini mendukung SVG dengan style atau script tertanam?","answer":"Ia menghapus blok <style> hanya via strip metadata kalau kamu mengaktifkannya — dan hanya kalau tag style dibungkus dalam <metadata>. Atribut style inline (style=\"fill:red\") dipertahankan. Blok <script> dipertahankan apa adanya.

This is what vehicle loans (KKB) and most pinjol (online loans) use, and the total interest over the loan is easy to predict. Effective (anuitas) interest calculates interest on the outstanding principal each month: as you pay down the loan, the interest portion shrinks and the principal portion grows. The monthly payment stays the same but the split changes. This is what mortgages (KPR) and most consumer loans at banks use. On a Rp 500M loan at 10% over 20 years, flat gives you a total interest of about Rp 500M, while effective gives you about Rp 632M — a big difference, which is why flat is sometimes marketed as \"cheaper\" even though the total cost is the same in absolute terms."},{"question":"Why does my amortization table end early when I add an extra payment?","answer":"When you enter an \"extra monthly payment\" and a month limit, the simulation adds that amount to every payment up to that month. This pays off the principal faster, so the loan reaches zero balance before the original tenor. The tool then truncates the table at the actual payoff month and shows a \"savings\" banner with the number of months and total interest you saved compared to the no-extra-payment baseline. Be careful: in the flat method, the interest portion of each payment is fixed regardless of how much principal is left, so adding extra only shortens the principal portion. In the effective method, the extra goes 100% to principal, which is what you want."},{"question":"Does this include fees, taxes, or insurance?","answer":"No. The tool works on principal, interest, and tenor only. It does not add admin fees, provision fees, insurance premiums, notarial fees, or any other charges that Indonesian lenders typically bundle. For KPR, ask your bank for the \"effective rate\" (suku bunga efektif) which already includes some of these — or compute the all-in cost yourself by adding the total fees to the principal in the input. The amortization table itself is mathematically exact for the inputs you give it, but the actual monthly debit from your account will usually be higher than the \"cicilan\" shown here."},{"question":"Can I export the amortization table to a spreadsheet?","answer":"Yes. The \"Export CSV\" button downloads loan-amortization.csv with the month number, date, payment, principal, interest, and balance columns. Open it in Excel, Google Sheets, or Numbers. The currency is plain decimal (not formatted with Rp/USD prefix) so spreadsheet apps recognize it as a number. Dates are ISO 8601 (YYYY-MM-DD) so they sort correctly. The CSV starts with the row immediately following the \"Calculate\" press, so if you change inputs you need to re-export."},{"question":"Is my loan data private?","answer":"Yes. The calculator is pure client-side JavaScript inlined in the HTML. There are no network calls, no API uploads, no analytics, no CDN. The principal, interest, and tenor you enter stay in your browser. The CSV download uses the standard browser <a download> click and writes to your local Downloads folder. You can model a proprietary or sensitive loan (e.g. your real KPR application) without any data being transmitted."}],"faq_id":[{"question":"Apa beda bunga flat dan efektif?","answer":"Bunga flat menghitung bunga dari pokok awal sepanjang tenor: bunga bulanan = P * (bunga tahunan) / 12, terlepas dari berapa sisa pokok. Ini yang dipakai kredit kendaraan (KKB) dan kebanyakan pinjol, dan total bunga sepanjang pinjaman mudah diprediksi. Bunga efektif (anuitas) menghitung bunga dari sisa pokok tiap bulan: begitu kamu membayar pokok, porsi bunga mengecil dan porsi pokok membesar. Cicilan tetap tapi split berubah. Ini yang dipakai KPR (Kredit Pemilikan Rumah) dan kebanyakan kredit konsumen di bank. Pada pinjaman Rp 500jt di 10% selama 20 tahun, flat memberi total bunga sekitar Rp 500jt, sedangkan efektif memberi sekitar Rp 632jt — beda besar, itulah kenapa flat kadang dipasarkan sebagai \"lebih murah\" padahal biaya total absolutnya kurang lebih sama."},{"question":"Kenapa tabel amortisasi saya berakhir lebih awal ketika saya tambah bayar lebih?","answer":"Ketika kamu masukkan \"bayar tambahan per bulan\" dan batas bulan, simulasi menambahkan jumlah itu ke tiap cicilan sampai bulan tersebut. Ini melunasi pokok lebih cepat, jadi pinjaman mencapai saldo nol sebelum tenor asli. Tool lalu memotong tabel di bulan pelunasan aktual dan menampilkan banner \"hemat\" dengan jumlah bulan dan total bunga yang dihemat dibanding baseline tanpa bayar tambahan. Hati-hati: di metode flat, porsi bunga tiap cicilan tetap terlepas dari sisa pokok, jadi tambahan hanya mempersingkat porsi pokok. Di metode efektif, tambahan 100% masuk ke pokok, yang kamu inginkan."},{"question":"Apakah ini termasuk biaya, pajak, atau asuransi?","answer":"Tidak. Tool bekerja pada pokok, bunga, dan tenor saja. Tidak menambahkan biaya admin, biaya provisi, premi asuransi, biaya notaris, atau charges lain yang biasanya dibundle lender Indonesia. Untuk KPR, tanyakan ke bank kamu \"suku bunga efektif\" yang sudah mencakup beberapa dari ini — atau hitung all-in cost sendiri dengan menambahkan total fee ke pokok di input. Tabel amortisasi sendiri secara matematis exact untuk input yang kamu berikan, tapi debit bulanan aktual dari rekening biasanya lebih tinggi dari \"cicilan\" yang ditampilkan di sini."},{"question":"Bisakah saya export tabel amortisasi ke spreadsheet?","answer":"Bisa. Tombol \"Export CSV\" mendownload loan-amortization.csv dengan kolom nomor bulan, tanggal, bayar, pokok, bunga, dan saldo. Buka di Excel, Google Sheets, atau Numbers. Mata uang adalah decimal biasa (tanpa prefix Rp/USD) supaya aplikasi spreadsheet mengenalinya sebagai angka. Tanggal adalah ISO 8601 (YYYY-MM-DD) supaya sort dengan benar. CSV dimulai dari baris segera setelah tekan \"Hitung\", jadi kalau kamu ubah input kamu perlu export ulang."},{"question":"Apakah data pinjaman saya privat?","answer":"Ya. Kalkulator adalah JavaScript murni sisi client yang di-inline di HTML. Tidak ada panggilan jaringan, tidak ada upload API, tidak ada analitik, tidak ada CDN. Pokok, bunga, dan tenor yang kamu masukkan tetap di browser kamu. Download CSV memakai klik <a download> standar browser dan menulis ke folder Downloads lokal. Kamu bisa model pinjaman proprietary atau sensitif (mis. aplikasi KPR kamu yang sebenarnya) tanpa data apa pun yang ditransmisikan."}]},{"id":"1e60a6d2-4566-4c06-9395-1b841a67b0b7","slug":"retirement-calculator","name":"Retirement Calculator","name_id":"Kalkulator Dana Pensiun","icon":"🧓","category":"finance","meta_description":"Estimate retirement fund with compound interest, monthly contribution, inflation adjustment, shortfall/surplus, recommended deposit.

Stocks historically return 8-11% nominal long-term, government bonds 6-7%, time deposits 4-5%. A 60/30/10 stock/bond/deposit mix might yield 7-8% nominal. Be conservative: if you assume 12% and only get 7%, your projection is off by 40%. Inflation in Indonesia has averaged 4-6% over the past two decades, so 4% is a reasonable forward assumption. If you want a stress test, run the calculator with 4% return and 6% inflation and see whether you are still on track."},{"question":"Why is the \"real value\" lower than the nominal fund?","answer":"Inflation. The nominal fund is the raw future-value calculation: how much money you would have in nominal rupiah (or dollars) at retirement. The real value is what that money is worth in today's purchasing power. If you retire in 25 years with Rp 5 billion nominal and average inflation is 4%, the real value is roughly Rp 5B / (1.04)^25 ≈ Rp 1.87B. So you have Rp 5B on paper but it buys what Rp 1.87B buys today. The shortfall/surplus is calculated on the real value, because that is what determines whether you can actually maintain your desired lifestyle. The target needed is also in today's money, which is why the income you enter should be \"in today's value\" — the tool inflates it implicitly through the real return calculation."},{"question":"How is \"needed fund\" calculated?","answer":"The needed fund is the present value (in today's money) of the annuity you would draw down during retirement, assuming the same real return rate (nominal return minus inflation, compounded). If you want Rp 15M per month for 25 years of retirement and the real return is 4% annual (which compounds to about 0.33% monthly), the formula is: needed = 15M * (1 - (1.0033)^-300) / 0.0033 ≈ Rp 2.6B in today's money. If the real return is zero or negative, the formula simplifies to income * months. This is the standard annuity-present-value formula used in financial planning, and it assumes you draw down the fund to zero by the end of your life expectancy (a common assumption — you can adjust by entering a higher life expectancy or longer retirement horizon to leave a bequest)."},{"question":"What if the recommended monthly deposit is much higher than what I can afford?","answer":"The tool gives you a math-optimal answer, not a budget answer. If the recommended deposit is 2x what you can afford, you have three options: (1) push your retirement age out (each extra year compounds massively), (2) lower your desired retirement income (a 20% reduction in target income cuts the needed fund by ~25% in present value terms), or (3) increase your expected return (risky — that is a market bet, not a guarantee). The danger advice (\"Target tidak realistis di Y tahun\") fires when the required monthly exceeds 5x your current contribution; that is usually a sign you need to either delay retirement significantly or accept a lower lifestyle."},{"question":"Is my financial data private?","answer":"Yes. The retirement calculator is pure client-side JavaScript inlined in the HTML. There are no network calls, no API uploads, no analytics, no CDN. Your age, current savings, monthly contribution, and expected return stay in your browser. The chart is generated inline as an SVG.

Saham historis return 8-11% nominal jangka panjang, obligasi pemerintah 6-7%, deposito 4-5%. Campuran 60/30/10 saham/obligasi/deposito mungkin memberi 7-8% nominal. Konservatiflah: kalau kamu asumsikan 12% dan hanya dapat 7%, proyeksi kamu meleset 40%. Inflasi di Indonesia rata-rata 4-6% selama dua dekade terakhir, jadi 4% adalah asumsi maju yang masuk akal. Kalau mau stress test, jalankan kalkulator dengan return 4% dan inflasi 6% dan lihat apakah kamu masih di jalur."},{"question":"Kenapa \"nilai riil\" lebih rendah dari dana nominal?","answer":"Inflasi. Dana nominal adalah kalkulasi nilai masa depan mentah: berapa banyak uang yang kamu punya dalam rupiah (atau dolar) nominal saat pensiun. Nilai riil adalah apa yang uang itu beli dalam daya beli hari ini. Kalau kamu pensiun 25 tahun dari sekarang dengan Rp 5 miliar nominal dan inflasi rata-rata 4%, nilai riilnya kira-kira Rp 5M / (1.04)^25 ≈ Rp 1.87M. Jadi kamu punya Rp 5M di atas kertas tapi itu membeli apa yang Rp 1.87M beli hari ini. Kurang/lebih dihitung pada nilai riil, karena itu yang menentukan apakah kamu bisa mempertahankan gaya hidup yang diinginkan. Target dibutuhkan juga dalam uang hari ini, itulah kenapa income yang kamu masukkan harus \"dalam nilai saat ini\" — tool meng-inflate-kan secara implisit melalui kalkulasi return riil."},{"question":"Bagaimana \"dana dibutuhkan\" dihitung?","answer":"Dana dibutuhkan adalah present value (dalam uang hari ini) dari annuity yang akan kamu tarik selama pensiun, dengan asumsi tingkat return riil yang sama (return nominal dikurangi inflasi, dimajemukkan). Kalau kamu mau Rp 15jt per bulan selama 25 tahun pensiun dan return riil 4% tahunan (yang menjadi sekitar 0.33% bulanan), formula: dibutuhkan = 15jt * (1 - (1.0033)^-300) / 0.0033 ≈ Rp 2.6M dalam uang hari ini. Kalau return riil nol atau negatif, formula menyederhanakan ke income * bulan. Ini adalah formula annuity-present-value standar yang dipakai dalam perencanaan keuangan, dan mengasumsikan kamu menarik dana ke nol di akhir harapan hidup (asumsi umum — kamu bisa menyesuaikan dengan memasukkan harapan hidup lebih tinggi atau horizon pensiun lebih panjang untuk meninggalkan warisan)."},{"question":"Bagaimana kalau rekomendasi setoran bulanan jauh lebih tinggi dari yang saya mampu?","answer":"Tool memberi jawaban optimal secara matematika, bukan jawaban budget. Kalau setoran yang direkomendasikan 2x dari yang kamu mampu, ada tiga opsi: (1) dorong usia pensiun ke luar (tiap tahun ekstra memajemukkan secara masif), (2) turunkan income pensiun yang diinginkan (pengurangan 20% pada target income memotong dana dibutuhkan ~25% dalam present value), atau (3) naikkan expected return (berisiko — itu pasar taruhan, bukan jaminan). Saran bahaya (\"Target tidak realistis di Y tahun\") muncul ketika setoran yang diperlukan melebihi 5x setoran kamu saat ini; biasanya itu pertanda kamu perlu menunda pensiun secara signifikan atau menerima gaya hidup lebih rendah."},{"question":"Apakah data keuangan saya privat?","answer":"Ya.

For each criterion, you also assign a weight from 1 to 10 that reflects how much that criterion matters to you. The tool multiplies the score by the weight for every cell, then sums those products to give the option's total. So if Option A scores 8/10 on Salary (weight 9) and 5/10 on Commute (weight 3), its weighted contribution from those two criteria is (8*9) + (5*3) = 87. The total is summed across all criteria, then the options are sorted by total descending. The top three get gold/silver/bronze styling, and the top option is shown as the recommendation in the winner card. The math is intentionally simple and transparent — there is no fuzzy logic, no hidden normalization, no surprise weighting."},{"question":"How should I choose the weights?","answer":"The weights are the most subjective part of the matrix and that is the point. A common approach is \"must-have vs nice-to-have\": if a criterion is essential (e.g. salary must cover your rent), give it a high weight (8-10). If it is a tie-breaker (e.g. free coffee), give it a low weight (1-3). Another approach is \"comparative weighting\": if Salary matters twice as much as Commute to you, set Salary weight = 8 and Commute weight = 4 (or 6 and 3, or 10 and 5 — any consistent ratio). The absolute scale (1-10) does not matter as much as the relative ratios between criteria. After you build the matrix, try flipping one weight from 5 to 9 and see if the winner changes — if not, the criterion is not actually doing work and you can drop it."},{"question":"What does the \"Saved Decisions\" list do?","answer":"Every time you click Export JSON, a snapshot of the current matrix (options, criteria, scores, weights) is saved to localStorage under the key decision-matrix-saved as a JSON array, max 10 entries. The \"Saved Decisions\" card at the bottom shows these snapshots with their name (auto-generated from the option names), timestamp, and a Load / Delete button pair. Load replaces the current matrix with the saved one. Delete removes it from the list. The list is local to this browser — it does not sync anywhere. If you want a permanent backup, use Export JSON and save the file to your device or cloud storage; you can re-import it later with the Import button."},{"question":"Can I compare more than 10 options or 10 criteria?","answer":"Technically yes, the tool will accept any number of options and criteria. Practically, the matrix becomes hard to read beyond 5-6 options (the table is wide on mobile) and beyond 5-6 criteria (you start losing the ability to differentiate scores consistently). For larger comparisons, consider grouping criteria into categories (e.g. \"Financial\" weight = sum of 3 sub-criteria, \"Lifestyle\" weight = sum of 3 sub-criteria) and running the matrix at the category level. Or build multiple matrices — one for \"must-haves\" filter, one for \"trade-off comparison\" — and combine the conclusions."},{"question":"Is my decision data private?","answer":"Yes.

Untuk tiap kriteria, kamu juga assign bobot 1 sampai 10 yang mencerminkan seberapa penting kriteria itu buat kamu. Tool mengalikan nilai dengan bobot untuk setiap cell, lalu menjumlahkan produk itu untuk memberikan total opsi. Jadi kalau Opsi A nilai 8/10 di Gaji (bobot 9) dan 5/10 di Commute (bobot 3), kontribusi tertimbangnya dari dua kriteria itu adalah (8*9) + (5*3) = 87. Total dijumlahkan lintas semua kriteria, lalu opsi diurutkan berdasarkan total descending. Tiga teratas mendapat style emas/perak/perunggu, dan opsi teratas ditampilkan sebagai rekomendasi di kartu pemenang. Matematikanya sengaja sederhana dan transparan — tidak ada logika fuzzy, tidak ada normalisasi tersembunyi, tidak ada bobot kejutan."},{"question":"Bagaimana cara memilih bobot?","answer":"Bobot adalah bagian paling subjektif dari matriks dan justru itu intinya. Pendekatan umum adalah \"wajib vs nice-to-have\": kalau kriteria esensial (mis. gaji harus覆盖 sewa), berikan bobot tinggi (8-10). Kalau itu tie-breaker (mis. kopi gratis), berikan bobot rendah (1-3). Pendekatan lain adalah \"pembobotan komparatif\": kalau Gaji 2x lebih penting dari Commute buat kamu, set bobot Gaji = 8 dan Commute = 4 (atau 6 dan 3, atau 10 dan 5 — rasio konsisten apa pun). Skala absolut (1-10) tidak sepenting rasio relatif antar kriteria. Setelah kamu bangun matriksnya, coba balik satu bobot dari 5 ke 9 dan lihat apakah pemenangnya berubah — kalau tidak, kriteria itu sebenarnya tidak bekerja dan kamu bisa drop."},{"question":"Apa yang dilakukan daftar \"Keputusan Tersimpan\"?","answer":"Tiap kali kamu klik Export JSON, snapshot matriks saat itu (opsi, kriteria, nilai, bobot) disimpan ke localStorage dengan key decision-matrix-saved sebagai array JSON, max 10 entri. Kartu \"Keputusan Tersimpan\" di bawah menampilkan snapshot ini dengan namanya (auto-generated dari nama opsi), timestamp, dan pasangan tombol Muat / Hapus.

Praktiknya, matriks jadi sulit dibaca di atas 5-6 opsi (tabel lebar di mobile) dan di atas 5-6 kriteria (kamu mulai kehilangan kemampuan untuk membedakan nilai secara konsisten). Untuk perbandingan lebih besar, pertimbangkan mengelompokkan kriteria ke kategori (mis. \"Finansial\" bobot = jumlah 3 sub-kriteria, \"Gaya Hidup\" bobot = jumlah 3 sub-kriteria) dan jalankan matriks di level kategori. Atau bangun beberapa matriks — satu untuk filter \"wajib\", satu untuk \"trade-off\" — dan gabungkan kesimpulannya."},{"question":"Apakah data keputusan saya privat?","answer":"Ya.

With only 25 possible keys, an attacker can try all of them in microseconds. This tool is for education, puzzles, and fun, not for protecting secrets. The brute force mode demonstrates this: it scores all 26 candidates and highlights the most likely plaintext. If you need real confidentiality, use AES-256 (a modern symmetric cipher) or X25519 + ChaCha20 (for key exchange + encryption). The Caesar cipher is historically interesting because it was used by Julius Caesar around 50 BC for military messages, and it illustrates the basic idea of substitution ciphers — every letter is replaced by another letter at a fixed offset."},{"question":"What is ROT13?","answer":"ROT13 is Caesar cipher with shift 13. The special property of shift 13 is that applying it twice returns the original text: ROT13(ROT13(x)) = x. This is because the English alphabet has 26 letters and 13 is exactly half of 26, so each letter maps to the letter 13 positions away, and mapping 13 positions away from that letter brings you back to the start. ROT13 is widely used online to obscure spoilers, puzzle answers, NSFW content, and mildly offensive jokes — anyone who wants to read the text can apply ROT13 in their head (or with a tool like this) and the original content is hidden from casual scanning. It is not encryption because there is no key — the shift is always 13."},{"question":"What does the brute force star marker mean?","answer":"The brute force mode runs all 26 shifts on your cipher text and scores each candidate plaintext by counting how many of the words match a small built-in list of ~100 common English words (\"the\", \"and\", \"to\", \"of\", \"is\", \"are\", etc.). The shift with the highest score gets a star marker. If your cipher text is short (under 30 characters) or contains mostly proper nouns / unusual words, the star may be wrong — common words are a heuristic, not a guarantee. Read each candidate by eye, and use the star as a hint, not a definitive answer. You can also use the copy button next to each candidate to grab that particular shift's output."},{"question":"What charset should I pick?","answer":"Use \"A-Z case-preserved\" (default) for most English text. It shifts A→A+shift, B→B+shift, etc. while keeping the case of the original letter, and passes numbers, punctuation, and whitespace through unchanged. Use \"a-z only\" or \"A-Z only\" if you want strict single-case behavior (useful for some puzzle formats). Use \"Printable ASCII (32-126)\" if your text contains non-letter characters that you also want shifted — for example, if you have an obfuscated file path or a string of mixed letters and digits where you want everything shifted. Note that with the ASCII option, spaces and punctuation are also shifted, which can make the output harder to read."},{"question":"Is my text private?","answer":"Yes. The cipher is pure client-side JavaScript inlined in the HTML. There are no network calls, no API uploads, no analytics, no CDN. Your plaintext, cipher text, and chosen shift stay in your browser.

Mode brute force mendemonstrasikan ini: ia menilai 26 kandidat dan menyorot plaintext paling mungkin.

Properti khusus dari shift 13 adalah menerapkan dua kali mengembalikan teks asli: ROT13(ROT13(x)) = x. Ini karena alfabet Inggris punya 26 huruf dan 13 persis setengah dari 26, jadi tiap huruf memetakan ke huruf 13 posisi jauhnya, dan memetakan 13 posisi jauhnya dari huruf itu membawa kamu kembali ke awal. ROT13 banyak dipakai online untuk mengaburkan spoiler, jawaban puzzle, konten NSFW, dan joke yang agak ofensif — siapa pun yang mau membaca teks bisa menerapkan ROT13 di kepala mereka (atau dengan tool seperti ini) dan konten asli tersembunyi dari pemindaian kasual. Itu bukan enkripsi karena tidak ada kunci — shift selalu 13."},{"question":"Apa arti marker bintang brute force?","answer":"Mode brute force menjalankan 26 shift pada teks sandi kamu dan menilai tiap kandidat plaintext dengan menghitung berapa banyak kata yang cocok dengan daftar kecil built-in ~100 kata umum Inggris (\"the\", \"and\", \"to\", \"of\", \"is\", \"are\", dll.). Shift dengan skor tertinggi mendapat marker bintang. Kalau teks sandi kamu singkat (di bawah 30 karakter) atau mengandung banyak proper noun / kata tidak biasa, bintang mungkin salah — kata umum adalah heuristik, bukan jaminan. Baca tiap kandidat dengan mata, dan pakai bintang sebagai petunjuk, bukan jawaban pasti. Kamu juga bisa pakai tombol salin di sebelah tiap kandidat untuk mengambil output shift tertentu itu."},{"question":"Charset mana yang harus saya pilih?","answer":"Pakai \"A-Z case-preserved\" (default) untuk kebanyakan teks Inggris. Ia menggeser A→A+shift, B→B+shift, dll. sambil mempertahankan case huruf asli, dan melewatkan angka, tanda baca, dan whitespace apa adanya. Pakai \"a-z saja\" atau \"A-Z saja\" kalau kamu ingin perilaku single-case ketat (berguna untuk beberapa format puzzle). Pakai \"Printable ASCII (32-126)\" kalau teks kamu mengandung karakter non-huruf yang juga ingin kamu geser — misalnya, kalau kamu punya path file yang di-obfuscate atau string campuran huruf dan digit di mana kamu ingin semuanya digeser. Catat bahwa dengan opsi ASCII, spasi dan tanda baca juga digeser, yang bisa membuat output lebih sulit dibaca."},{"question":"Apakah teks saya privat?","answer":"Ya. Sandi adalah JavaScript murni sisi client yang di-inline di HTML. Tidak ada panggilan jaringan, tidak ada upload API, tidak ada analitik, tidak ada CDN. Plaintext, teks sandi, dan shift yang kamu pilih tetap di browser. Tombol salin memakai API clipboard standar browser. Bahkan penilaian brute force (yang memakai daftar kata built-in kecil) sepenuhnya lokal. Kamu bisa encode atau decode teks apa pun tanpa data apa pun yang ditransmisikan."}]},{"id":"7b5235c2-2b95-493c-80ca-69e44b1b96a6","slug":"gradient-extractor","name":"Gradient Extractor","name_id":"Ekstrak Gradient Gambar","icon":"🎨","category":"developer","meta_description":"Upload an image, extract 3-10 dominant colors via frequency quantization, render as linear/radial gradient, export CSS / JSON / PNG. 100% offline, no CDN.","meta_description_id":"Upload gambar, ekstrak 3-10 warna dominan via kuantisasi frekuensi, render sebagai gradient linear/radial, export CSS / JSON / PNG. 100% offline, tanpa CDN.","long_description":"A pure-JavaScript image color extractor.

(1) The image is downscaled to 200x200 max (for speed) and drawn to a hidden canvas. (2) Each pixel's R, G, B values are quantized by bit-shifting (2-bit, 3-bit, or 4-bit per channel) so that similar colors merge into \"buckets\" — 2-bit gives 64 buckets (8 per channel), 3-bit gives 512, 4-bit gives 4096. (3) A frequency map counts how many pixels fall into each bucket, then the top 40 buckets are clustered with a 8-iteration K-means into the requested number of centroids. The K-means step merges over-represented buckets and splits under-represented ones to give an even palette. Finally, the percentage of each output color is the sum of pixels in the buckets that merged into its centroid. The whole pipeline runs in JS on the canvas pixel data, no WebAssembly, no network."},{"question":"What granularity should I pick?","answer":"It depends on the image. For photographs and complex gradients, 3-bit (medium, default) gives 5-10 distinct dominant colors with smooth transitions. For flat-design illustrations, posters, or logo art, 2-bit (low) gives a posterized palette of 3-6 strong colors. For detailed paintings or photos with many subtle hues, 4-bit (high) gives finer differentiation but may include near-duplicate colors. If the result looks \"too few\" colors, raise the granularity; if it looks \"too many similar\" colors, lower it. Also, more colors (the top selector) plus higher granularity is the most detailed; fewer colors plus lower granularity is the most abstracted. Try 3 colors at 2-bit for a Bauhaus look, or 10 colors at 4-bit for a full spectrum."},{"question":"How is the gradient rendered?","answer":"The preview uses a CSS linear-gradient or radial-gradient background, with one color stop per palette color, evenly distributed from 0% to 100% of the gradient. The \"Linear 90°\" option runs left-to-right (the default), \"45°\" runs bottom-left to top-right, \"180°\" runs bottom-to-top, and \"Radial\" uses a circle with the first color at the center and the last at the edge. The PNG download renders the same gradient to a 1200x480 canvas via canvas createLinearGradient / createRadialGradient, then exports as PNG with the standard toBlob. The CSS download saves a .css file with a .gradient class that you can paste into any project."},{"question":"Is my image private?","answer":"Yes. The extractor is pure client-side JavaScript inlined in the HTML. There are no network calls, no API uploads, no analytics, no CDN. Your image is loaded via FileReader (which reads the file from your local disk) and drawn to a hidden canvas, then the pixel data is processed locally. The downscaled copy, the palette, the gradient, and the exported PNG are all generated in your browser. You can extract colors from private photos, customer logos, or proprietary product images without any data being transmitted. The only file operations are FileReader for the drop-zone and the standard <a download> for the CSS/PNG exports."},{"question":"Can I extract colors from a URL?","answer":"No, the tool only accepts local files via the file picker or drag-and-drop. Adding URL-based loading would require fetching the image from a remote server, which would leak the URL (and any sensitive image path or query parameters) to whatever CORS proxy or image host serves it. The privacy-first design is intentional: the image never leaves your device. If you have an image at a URL that you want to process, download it first (right-click → Save As, or use a download manager), then drop the local file into the tool. The tool also accepts any image format the browser can decode — PNG, JPG, WebP, GIF, BMP, ICO, AVIF (on supported browsers) — so the local workflow is flexible."}],"faq_id":[{"question":"Bagaimana kerja ekstraksi warna?","answer":"Tool berjalan dalam tiga tahap. (1) Gambar di-downscale ke max 200x200 (untuk kecepatan) dan digambar ke canvas tersembunyi. (2) Nilai R, G, B tiap pixel di-kuantisasi dengan bit-shift (2-bit, 3-bit, atau 4-bit per channel) supaya warna serupa bergabung ke \"bucket\" — 2-bit memberi 64 bucket (8 per channel), 3-bit memberi 512, 4-bit memberi 4096. (3) Peta frekuensi menghitung berapa banyak pixel jatuh ke tiap bucket, lalu 40 bucket teratas di-cluster dengan 8-iterasi K-means ke jumlah centroid yang diminta. Langkah K-means menggabungkan bucket yang terlalu terwakili dan memecah yang kurang terwakili untuk memberikan palet yang merata. Akhirnya, persentase tiap warna output adalah jumlah pixel di bucket yang bergabung ke centroid-nya. Seluruh pipeline berjalan di JS pada data pixel canvas, tanpa WebAssembly, tanpa jaringan."},{"question":"Granularitas mana yang harus saya pilih?","answer":"Tergantung gambar. Untuk foto dan gradient kompleks, 3-bit (sedang, default) memberi 5-10 warna dominan berbeda dengan transisi halus. Untuk ilustrasi flat-design, poster, atau seni logo, 2-bit (rendah) memberi palet ter-posterisasi 3-6 warna kuat. Untuk lukisan detail atau foto dengan banyak nuansa halus, 4-bit (tinggi) memberi differensiasi lebih halus tapi mungkin termasuk warna near-duplikat. Kalau hasilnya terlihat \"terlalu sedikit\" warna, naikkan granularitas; kalau terlihat \"terlalu banyak serupa\" warna, turunkan. Juga, lebih banyak warna (selector atas) plus granularitas lebih tinggi adalah yang paling detail; lebih sedikit warna plus granularitas lebih rendah adalah yang paling diabstraksi. Coba 3 warna di 2-bit untuk tampilan Bauhaus, atau 10 warna di 4-bit untuk spektrum penuh."},{"question":"Bagaimana gradient di-render?","answer":"Preview memakai background CSS linear-gradient atau radial-gradient, dengan satu color stop per warna palet, didistribusikan merata dari 0% ke 100% gradient. Opsi \"Linear 90°\" berjalan kiri-ke-kanan (default), \"45°\" berjalan dari kiri-bawah ke kanan-atas, \"180°\" berjalan dari bawah-ke-atas, dan \"Radial\" menggunakan circle dengan warna pertama di tengah dan terakhir di tepi. Download PNG me-render gradient yang sama ke canvas 1200x480 via canvas createLinearGradient / createRadialGradient, lalu export sebagai PNG dengan toBlob standar. Download CSS menyimpan file .css dengan class .gradient yang bisa kamu paste ke proyek mana pun."},{"question":"Apakah gambar saya privat?","answer":"Ya. Ekstraktor adalah JavaScript murni sisi client yang di-inline di HTML. Tidak ada panggilan jaringan, tidak ada upload API, tidak ada analitik, tidak ada CDN. Gambar kamu dimuat via FileReader (yang membaca file dari disk lokal kamu) dan digambar ke canvas tersembunyi, lalu data pixel diproses lokal. Salinan yang di-downscale, palet, gradient, dan PNG yang di-export semua di-generate di browser. Kamu bisa ekstrak warna dari foto privat, logo pelanggan, atau gambar produk proprietary tanpa data apa pun yang ditransmisikan. Satu-satunya operasi file adalah FileReader untuk drop-zone dan <a download> standar untuk export CSS/PNG."},{"question":"Bisakah saya ekstrak warna dari URL?","answer":"Tidak, tool hanya menerima file lokal via file picker atau drag-and-drop. Menambah loading berbasis URL akan memerlukan fetch gambar dari server remote, yang akan membocorkan URL (dan parameter path atau query image sensitif) ke proxy CORS atau host image apa pun yang menyediakannya. Desain privasi-utama adalah disengaja: gambar tidak pernah meninggalkan device kamu. Kalau kamu punya gambar di URL yang ingin kamu proses, download dulu (klik-kanan → Save As, atau pakai download manager), lalu drop file lokal ke tool. Tool juga menerima format gambar apa pun yang bisa di-decode browser — PNG, JPG, WebP, GIF, BMP, ICO, AVIF (di browser yang didukung) — jadi workflow lokal fleksibel."}]},{"id":"49516679-6197-4f3d-8396-f3f6db2784da","slug":"rangkuman-bodo-amat","name":"Rangkuman Bodo Amat (The Subtle Art of Not Giving a F*ck)","name_id":"Rangkuman Bodo Amat","icon":"📖","category":"reading","meta_description":"Complete summary of Mark Manson's \"The Subtle Art of Not Giving a F*ck\" in Indonesian. 9 BAB, 39 sub-bab, expandable accordion. 100% offline.","meta_description_id":"Rangkuman lengkap buku \"The Subtle Art of Not Giving a F*ck\" karya Mark Manson dalam Bahasa Indonesia. 9 BAB, 39 sub-bab, accordion yang bisa dibuka-tutup. 100% offline.","long_description":"Rangkuman lengkap buku \"The Subtle Art of Not Giving a F*ck\" (terjemahan Bahasa Indonesia: \"Bodo Amat\") karya Mark Manson.

Kids' bodies change as they grow, so the WHO uses BMI-for-age z-scores — how far a child is from the median BMI of other children the same age and sex. A 10-year-old and a 15-year-old with the same BMI can be in very different categories."},{"question":"What are the cutoffs?","answer":"WHO categories for 5–19 years: thin (z-score below -2), healthy weight (-2 to +1), overweight (+1 to +2), obese (above +2). These are international standards, not country-specific."},{"question":"How accurate is the z-score?","answer":"The tool uses the official WHO LMS parameters (L, M, S) for BMI-for-age by sex, sampled yearly from 5 to 19 years with linear interpolation between. For exact percentile readings, ask your pediatrician — they can plot BMI on a full WHO chart."},{"question":"Should I act on the result?","answer":"BMI is one signal among many. It does not measure body composition (muscle vs fat), puberty timing, or ethnicity differences. Use it as a starting point for a conversation with your pediatrician rather than a verdict."},{"question":"Is my child's data private?","answer":"Yes.

Anak usia 10 dan 15 tahun dengan BMI sama bisa masuk kategori sangat berbeda."},{"question":"Apa ambang batasnya?","answer":"Kategori WHO untuk 5–19 tahun: kurus (z-score di bawah -2), berat sehat (-2 sampai +1), berat berlebih (+1 sampai +2), obesitas (di atas +2). Ini standar internasional, bukan spesifik negara."},{"question":"Seberapa akurat z-score-nya?","answer":"Tool memakai parameter LMS resmi WHO (L, M, S) untuk BMI-untuk-usia berdasarkan jenis kelamin, diambil sampel per tahun dari 5 sampai 19 tahun dengan interpolasi linier di antaranya.

The three SHA-family digests use the browser Web Crypto API, so they are cryptographically identical to openssl/openssl dgst, sha1sum, sha256sum, and shasum. MD5 uses a custom pure-JS RFC 1321 implementation and produces bit-identical output to the PHP md5() function and the Linux md5sum binary."},{"question":"Is this cryptographically secure?","answer":"SHA-256 and SHA-512 are secure and recommended for password storage, file integrity verification, and digital signatures. SHA-1 is no longer collision-resistant and should not be used for new cryptographic designs. MD5 is broken for collision resistance and should be used only for legacy compatibility, file deduplication, or non-security checksums. The tool itself runs locally — your input is never sent to any server."},{"question":"Why does the tool run offline?","answer":"SHA-1/256/512 use the browser SubtleCrypto API which is built into the JS runtime. MD5 is not part of Web Crypto (because it is considered insecure), so a compact ~50-line RFC 1321 implementation is bundled inline in the HTML. Together this means the page does a single static file fetch and then works forever, even on a plane or behind a firewall."},{"question":"How do I hash a file?","answer":"Open the file in any text editor, select all, copy, paste into the input. For binary files, use the SHA-256/512 mode via SubtleCrypto in your own script — the tool is designed for text. The Batch tab accepts one string per line; for file lists, paste one path per line and hash each path string (it is a hash of the path, not of the file content)."},{"question":"Is my data private?","answer":"Yes. Hash generation is fully client-side JavaScript. There are no network calls, no telemetry, no logs. The history of last 10 hashes is kept in memory only — refresh the page and it is gone. Use it for production tokens and passwords without worry."}],"faq_id":[{"question":"Algoritma apa saja yang didukung?","answer":"MD5 (128-bit, 32 karakter hex), SHA-1 (160-bit, 40 karakter hex), SHA-256 (256-bit, 64 karakter hex), dan SHA-512 (512-bit, 128 karakter hex). Ketiga digest keluarga SHA pakai Web Crypto API browser, jadi identik kriptografis dengan openssl/openssl dgst, sha1sum, sha256sum, dan shasum. MD5 pakai implementasi RFC 1321 JS murni kustom dan menghasilkan output bit-identik dengan fungsi PHP md5() dan binary md5sum Linux."},{"question":"Apakah ini aman secara kriptografis?","answer":"SHA-256 dan SHA-512 aman dan direkomendasikan untuk penyimpanan password, verifikasi integritas file, dan tanda tangan digital. SHA-1 sudah tidak collision-resistant dan tidak boleh dipakai untuk desain kriptografis baru. MD5 rusak untuk collision resistance dan sebaiknya hanya dipakai untuk kompatibilitas legacy, deduplikasi file, atau checksum non-keamanan. Tool itu sendiri berjalan lokal — input kamu tidak pernah dikirim ke server mana pun."},{"question":"Kenapa tool ini berjalan offline?","answer":"SHA-1/256/512 pakai SubtleCrypto API browser yang built-in di runtime JS. MD5 bukan bagian Web Crypto (karena dianggap tidak aman), jadi implementasi RFC 1321 compact ~50 baris di-bundle inline di HTML. Bersama-sama ini berarti halaman melakukan satu kali fetch file statis dan kemudian bekerja selamanya, bahkan di pesawat atau di belakang firewall."},{"question":"Bagaimana cara hash file?","answer":"Buka file di text editor mana pun, select all, copy, paste ke input. Untuk file biner, pakai mode SHA-256/512 via SubtleCrypto di skrip kamu sendiri — tool ini dirancang untuk teks. Tab Batch menerima satu string per baris; untuk daftar file, tempel satu path per baris dan hash string path-nya (ini hash dari path, bukan dari konten file)."},{"question":"Apakah data saya privat?","answer":"Ya. Pembuatan hash sepenuhnya JavaScript sisi klien. Tidak ada panggilan jaringan, tidak ada telemetry, tidak ada log. Riwayat 10 hash terakhir disimpan di memori saja — refresh halaman dan hilang.

It does NOT support anchors and aliases (& and *), tags (!!str, !!int), flow style ({a: 1} and [1, 2]), multi-document streams (--- separators), or custom types. For full YAML 1.2, use a dedicated library — this tool is sized for human-edited config files and Kubernetes manifests."},{"question":"Why use YAML over JSON?","answer":"YAML is more compact (no curly braces or commas), allows comments (#), and treats indentation as syntax (so structure is visible at a glance). Common use cases: Kubernetes manifests, Docker Compose, GitHub Actions workflows, Ansible playbooks, and any human-edited config file. JSON is more universal as a wire format — APIs almost always speak JSON, while YAML is mostly for files."},{"question":"Are quoted strings preserved on round-trip?","answer":"Yes. Strings that need quoting (because they contain a colon, hash, special characters, or look like numbers/booleans) are quoted in the YAML output, and the parser reads them back identically. Simple identifier-like strings (\"hello\", \"version\") are emitted without quotes, and parsed back as strings. The only loss is whitespace differences — for example, trailing whitespace inside a quoted string is preserved exactly, but unquoted strings may be re-quoted if they contain characters that trigger quoting on the second pass."},{"question":"What does the Swap button do?","answer":"Swap moves the Output text into the Input field and flips the conversion direction in one click. This is the standard \"round-trip\" workflow: paste JSON in, convert to YAML, swap, convert back to JSON. If the two JSON outputs are identical (modulo formatting), the YAML round-trip is lossless. If they differ, you have found a YAML feature the parser does not support (e.g. an anchor or a flow-style mapping)."},{"question":"Is my data private?","answer":"Yes.

String mirip identifier sederhana (\"hello\", \"version\") di-emit tanpa quote, dan di-parse kembali sebagai string. Satu-satunya kehilangan adalah perbedaan whitespace — sebagai contoh, trailing whitespace di dalam string ber-quote dipertahankan persis, tapi string tidak ber-quote mungkin di-quote ulang jika mereka berisi karakter yang memicu quoting di pass kedua."},{"question":"Apa fungsi tombol Swap?","answer":"Swap memindahkan teks Output ke field Input dan flip arah konversi dalam satu klik.

A 50% margin on a $150 item means you keep $75 as profit (and $75 was cost). The two numbers are not the same: 50% margin = 100% markup. The tool solves for selling price given a target margin, and shows the equivalent markup in the result sub-line."},{"question":"How do I calculate percentage change correctly?","answer":"Percentage change is always (new − old) / old × 100. The old value is the base — never the new value, never the average. A common mistake is dividing by the new value, which gives a different (wrong) number. For example, going from 100 to 150 is a +50% change ((150−100)/100), not +33% (which would be (150−100)/150, a meaningless figure for growth)."},{"question":"What does \"base value\" mode solve?","answer":"Mode 3 answers \"X is Y% of what?\" Given the result and the percentage, it returns the base.

It is the kind of question that comes up in tax (\"tax is 11% of price, I paid $50 tax, price = ?\"), commission (\"commission is 5% of sale, I earned $200, sale = ?\"), and discount (\"discount is 20% of list, I saved $40, list = ?\") problems."},{"question":"Can I get more than 10 entries in history?","answer":"The cap is 10 to keep the UI tidy on phones. If you need a longer record, copy each calculation as you go (the Copy button captures both the description and the result). For batch calculations, you can also leave the page open and just keep typing — each new value pushes the oldest off, so the most recent 10 are always there."},{"question":"Is my data private?","answer":"Yes. The math is pure JavaScript running in the browser. The history is held in memory only and disappears on page refresh. There are no network calls, no analytics, no third-party scripts. You can use the tool for sensitive financial calculations (margin, pricing, commission rates) without any data leaving your device."}],"faq_id":[{"question":"Apa beda markup dan margin?","answer":"Markup dan margin keduanya cara mengekspresikan laba pada penjualan, tapi mereka menggunakan basis berbeda. Markup = laba / modal × 100. Markup 50% pada item $100 berarti kamu tambah $50, menjual di $150. Margin = laba / revenue × 100. Margin 50% pada item $150 berarti kamu menyimpan $75 sebagai laba (dan $75 adalah modal). Dua angka itu tidak sama: margin 50% = markup 100%. Tool menyelesaikan harga jual dari target margin, dan menampilkan markup ekuivalen di sub-baris hasil."},{"question":"Bagaimana menghitung perubahan % dengan benar?","answer":"Perubahan % selalu (baru − lama) / lama × 100. Nilai lama adalah basis — tidak pernah nilai baru, tidak pernah rata-rata. Kesalahan umum adalah membagi dengan nilai baru, yang memberikan angka berbeda (salah). Sebagai contoh, pergi dari 100 ke 150 adalah perubahan +50% ((150−100)/100), bukan +33% (yang akan jadi (150−100)/150, angka tidak bermakna untuk pertumbuhan)."},{"question":"Apa yang diselesaikan mode \"nilai dasar\"?","answer":"Mode 3 menjawab \"X adalah Y% dari berapa?\". Diberikan hasil dan persentase, mengembalikan basis. Contoh: 30 adalah 15% dari 200. Ini adalah inversi Mode 1, berguna ketika kamu punya nilai target dan persentase yang dikenal dari total dan perlu mencari total. Ini jenis pertanyaan yang muncul di masalah pajak (\"pajak 11% dari harga, saya bayar $50 pajak, harga = ?\"), komisi (\"komisi 5% dari penjualan, saya menghasilkan $200, penjualan = ?\"), dan diskon (\"diskon 20% dari daftar, saya hemat $40, daftar = ?\")."},{"question":"Bisakah saya dapat lebih dari 10 entri di riwayat?","answer":"Batasnya 10 untuk menjaga UI rapi di HP. Kalau kamu butuh catatan lebih panjang, salin tiap kalkulasi sambil jalan (tombol Salin mengambil deskripsi dan hasil). Untuk kalkulasi batch, kamu juga bisa membiarkan halaman tetap terbuka dan terus mengetik — tiap nilai baru mendorong yang tertua keluar, jadi 10 yang terbaru selalu ada."},{"question":"Apakah data saya privat?","answer":"Ya. Matematikanya adalah JavaScript murni yang berjalan di browser. Riwayat disimpan di memori saja dan hilang pada refresh halaman. Tidak ada panggilan jaringan, tidak ada analytics, tidak ada skrip pihak ketiga. Kamu bisa pakai tool untuk kalkulasi finansial sensitif (margin, harga, tarif komisi) tanpa data apa pun meninggalkan device kamu."}]},{"id":"d6f0a1b2-3c4d-4e5f-6a7b-8c9d0e1f2a3b","slug":"csv-json-converter","name":"CSV ↔ JSON Converter","name_id":"Konverter CSV ↔ JSON","icon":"⇄","category":"developer","meta_description":"Convert CSV to JSON and JSON to CSV.

Inside a quoted field, the delimiter and newline are treated as literal characters (not separators). To include a literal double-quote inside a quoted field, double it (\"\") — that is the CSV standard. So a cell with the value He said \"hi\" looks like \"He said \"\"hi\"\"\" in CSV. The parser handles this correctly; the value He said \"hi\" is what you get back in JSON."},{"question":"What is the difference between array-of-objects and array-of-arrays output?","answer":"Array of objects uses the first row as a header and produces one object per data row, with the header values as keys. This is the most common JSON representation for tabular data and matches what most APIs and downstream tools expect. Array of arrays emits every row (including the header) as a positional array. This preserves the exact row order with no key collisions and is useful when the header row contains duplicates, or when you want positional access. Toggle the option in the JSON output settings to switch."},{"question":"Why does the tool use a custom CSV parser instead of a library?","answer":"To keep the tool fully offline and zero-dependency. The standard library CSV parsers (PapaParse, csv-parse) are excellent but require either a CDN script or a build step. The in-house parser handles the 95% case (quoted fields, escaped quotes, multi-line values, custom delimiter, header detection) in about 60 lines of JS. It does not handle every edge of RFC 4180 (e.g. CR-only line endings, BOM handling beyond standard UTF-8) but it covers what real CSV files in the wild actually use."},{"question":"What does the Swap button do?","answer":"Swap moves the Output text into the Input field and flips the conversion direction in one click. This is the standard \"round-trip\" workflow: paste CSV in, convert to JSON, swap, convert back to JSON-as-CSV. If the two CSV outputs (modulo formatting and the object-to-array transformation) are identical, the round-trip is lossless. If they differ, you have found a CSV feature the parser does not preserve (e.g. a leading space inside a quoted field that the second pass trim-clipped)."},{"question":"Is my data private?","answer":"Yes.

Di dalam field ber-quote, delimiter dan newline diperlakukan sebagai karakter literal (bukan separator). Untuk menyertakan double-quote literal di dalam field ber-quote, dobelkan (\"\") — itu standar CSV. Jadi cell dengan nilai He said \"hi\" terlihat seperti \"He said \"\"hi\"\"\" di CSV.

Ini representasi JSON paling umum untuk data tabel dan cocok dengan yang diharapkan kebanyakan API dan tool hilir. Array of arrays emit setiap baris (termasuk header) sebagai array posisional.

A restaurant landing page reads better with \"bacon ipsum\" — it sets the tone. A hipster coffee shop landing page reads better with hipster ipsum.

Each paragraph has 3-6 sentences; each sentence has 6-16 words. So 5 paragraphs is roughly 200-400 words. Words mode generates sentences until the target word count is reached, then truncates the last sentence to fit cleanly.

That means if you click Generate twice within the same minute, you get the same output — useful for comparing layouts against identical copy. At the top of the next minute, the seed changes and you get fresh text. This is also why the Source tab always shows the same text you saw in Rendered: they are generated together, not separately."},{"question":"When should I use HTML output vs plain?","answer":"HTML output wraps each paragraph in a

Binary is base 2 (each digit is 0 or 1) — the native format of computers. Hex is base 16 (digits 0-9, A-F) — the most common shorthand for binary because each hex digit represents 4 binary digits, so 4 bytes (32 bits) become 8 hex characters. Base32 is base 32 (alphabet A-Z and 2-7) — less compact than hex but case-insensitive and URL-safe, used in TOTP secrets and some file systems. Octal is base 8 (digits 0-7) — older Unix file permissions and some assembly languages. They are interchangeable representations; the tool lets you pick whichever is most convenient for the context."},{"question":"How does the UTF-8 handling work?","answer":"The tool operates on bytes, not characters. The encode step uses TextEncoder to convert the input string to a UTF-8 byte array, then formats each byte in the chosen representation. The decode step parses the encoded form back to a byte array, then uses TextDecoder with the fatal flag to convert bytes back to a string. If the byte array is not valid UTF-8, the decoder throws and the tool falls back to a lossy ASCII visualization (replacing each non-ASCII byte with a dot). This means emoji and accented characters round-trip cleanly in the encode/decode direction, but pasting random binary that is not UTF-8 will give you the lossy fallback."},{"question":"Why is Base32 padded with = signs?","answer":"Base32 represents bytes in 5-bit groups. The input byte count is rarely a multiple of 5, so the output is padded with = signs to make its length a multiple of 8 characters. This is the RFC 4648 standard. The decoder strips trailing = signs before processing, so you can paste Base32 with or without the padding. The alphabet is the standard A-Z, 2-7 (32 symbols), which is why Base32 is case-insensitive — the encoder emits uppercase by convention, but the decoder accepts both cases."},{"question":"What does the separator option do on the Decode tab?","answer":"By default the decoder strips all whitespace, so a hex string with spaces, a binary string with spaces, or an octal string with newlines all parse correctly. The separator field lets you declare a specific separator (e.g. a colon, a comma, or \"0x\") that you want preserved in the output display.

Biner adalah basis 2 (tiap digit 0 atau 1) — format asli komputer. Hex adalah basis 16 (digit 0-9, A-F) — singkatan paling umum untuk biner karena tiap digit hex merepresentasikan 4 digit biner, jadi 4 byte (32 bit) menjadi 8 karakter hex. Base32 adalah basis 32 (alfabet A-Z dan 2-7) — kurang ringkas dari hex tapi case-insensitive dan URL-safe, dipakai di secret TOTP dan beberapa file system. Oktal adalah basis 8 (digit 0-7) — permission file Unix lama dan beberapa bahasa assembly. Mereka adalah representasi yang dapat dipertukarkan; tool memungkinkan kamu pilih mana pun yang paling удобно untuk konteksnya."},{"question":"Bagaimana kerja penanganan UTF-8?","answer":"Tool beroperasi pada byte, bukan karakter. Langkah encode memakai TextEncoder untuk mengonversi string input ke array byte UTF-8, lalu memformat tiap byte dalam representasi yang dipilih. Langkah decode mem-parse bentuk ter-encode kembali ke array byte, lalu memakai TextDecoder dengan flag fatal untuk mengonversi byte kembali ke string. Kalau array byte bukan UTF-8 valid, decoder melempar error dan tool fallback ke visualisasi ASCII lossy (mengganti tiap byte non-ASCII dengan titik). Ini berarti emoji dan karakter aksen round-trip dengan bersih di arah encode/decode, tapi menempel biner acak yang bukan UTF-8 akan memberimu fallback lossy."},{"question":"Kenapa Base32 di-padding dengan tanda =?","answer":"Base32 merepresentasikan byte dalam grup 5-bit. Jumlah byte input jarang merupakan kelipatan 5, jadi output di-padding dengan tanda = untuk membuat panjangnya kelipatan 8 karakter. Ini standar RFC 4648. Decoder memotong tanda = di akhir sebelum memproses, jadi kamu bisa menempel Base32 dengan atau tanpa padding. Alfabetnya adalah standar A-Z, 2-7 (32 simbol), itulah kenapa Base32 case-insensitive — encoder emit huruf besar berdasarkan konvensi, tapi decoder menerima kedua kasus."},{"question":"Apa yang dilakukan opsi separator di tab Decode?","answer":"Secara default decoder menghapus semua whitespace, jadi string hex dengan spasi, string biner dengan spasi, atau string oktal dengan newline semua parse dengan benar. Field separator memungkinkan kamu mendeklarasikan separator spesifik (mis. titik dua, koma, atau \"0x\") yang ingin kamu pertahankan di tampilan output. Decoder sendiri tidak peduli separator apa yang kamu pakai; dia hanya menghapus semua karakter non-hex/non-biner/non-oktal sebelum parsing. Field tersebut kebanyakan untuk dokumentasi — tempel input terformat kamu, lihat ia ter-parse dengan benar."},{"question":"Apakah data saya privat?","answer":"Ya. Encoder dan decoder adalah implementasi JavaScript murni dari algoritma standar, di-inline di HTML. Tidak ada panggilan jaringan dan tidak ada CDN.

For each compounding period (monthly, quarterly, etc.) it adds the per-period contribution, then multiplies the new balance by (1 + annual_rate / periods_per_year). This handles arbitrary compounding frequencies correctly. The per-period contribution is (monthly_contribution × 12 / periods_per_year), so the total annual contribution matches your monthly input regardless of the compounding frequency. The \"Contribute at start of month\" toggle controls whether the contribution is added before or after the interest accrues in that period."},{"question":"What is the real (inflation-adjusted) value?","answer":"The real value is what your nominal future value would buy in today's prices, accounting for inflation. The formula is real = nominal / (1 + inflation_rate)^years. So if you end up with Rp 1 billion after 20 years and inflation was 3% per year, the real value is Rp 1B / 1.03^20 = Rp 554 million in today's money. This tells you whether your investment is actually growing in purchasing power or just keeping up with rising prices. A 6% return with 3% inflation is a real 3% return, which doubles purchasing power in ~24 years."},{"question":"How does the tax on gains work?","answer":"Tax is applied once at the end, on the total interest earned (not on each period). The tool sums all interest over the lifetime of the investment, multiplies by your tax rate, and shows the tax owed and the net after-tax value. This is a simplification — actual tax rules may tax gains annually, allow cost-basis adjustments, or apply different rates to different holding periods. Use the tool for planning scenarios, not for tax filing. The tax field is optional; set to 0% for tax-advantaged accounts (401k, Roth IRA, Indonesian Reksa Dana)."},{"question":"What is the difference between compound frequencies?","answer":"Compounding frequency controls how often interest is added to the balance. Monthly means interest is calculated 12 times per year, quarterly 4 times, semi-annually 2 times, annually once. More frequent compounding produces a slightly higher final value because interest earns interest sooner. For a 6% annual rate over 20 years on Rp 10M with no contributions: monthly compounding gives Rp 33.1M, quarterly gives Rp 32.9M, annual gives Rp 32.1M. The difference is small for low rates and short periods, larger for high rates over decades. Most savings accounts and CDs compound monthly; most bonds compound semi-annually."},{"question":"Is my data private?","answer":"Yes. The math is pure JavaScript inlined in the HTML.

You can use the tool to plan your personal finances, model retirement scenarios, or estimate loan costs without any data being transmitted."}],"faq_id":[{"question":"Bagaimana bunga majemuk dihitung dengan setoran bulanan?","answer":"Tool menjalankan simulasi periode demi periode. Untuk tiap periode compounding (bulanan, kuartalan, dll.) ia menambah setoran per-periode, lalu mengalikan saldo baru dengan (1 + tarif_tahunan / periode_per_tahun). Ini menangani frekuensi compounding sembarang dengan benar. Setoran per-periode adalah (setoran_bulanan × 12 / periode_per_tahun), jadi total setoran tahunan cocok dengan input bulanan kamu terlepas dari frekuensi compounding. Toggle \"Setor di awal bulan\" mengontrol apakah setoran ditambahkan sebelum atau setelah bunga bertambah di periode itu."},{"question":"Apa itu nilai riil (adjusted inflasi)?","answer":"Nilai riil adalah apa yang bisa dibeli oleh nilai nominal masa depan kamu dalam harga hari ini, dengan memperhitungkan inflasi. Formulanya adalah real = nominal / (1 + tarif_inflasi)^tahun. Jadi kalau kamu berakhir dengan Rp 1 miliar setelah 20 tahun dan inflasi 3% per tahun, nilai riilnya adalah Rp 1M / 1.03^20 = Rp 554 juta dalam uang hari ini. Ini memberitahu kamu apakah investasimu benar-benar tumbuh dalam daya beli atau hanya mengikuti harga yang naik. Return 6% dengan inflasi 3% adalah return riil 3%, yang menggandakan daya beli dalam ~24 tahun."},{"question":"Bagaimana kerja pajak atas bunga?","answer":"Pajak diterapkan sekali di akhir, atas total bunga yang dihasilkan (bukan di tiap periode). Tool menjumlahkan semua bunga selama masa investasi, mengalikan dengan tarif pajak kamu, dan menampilkan pajak terutang dan nilai bersih setelah pajak. Ini adalah penyederhanaan — aturan pajak aktual mungkin memajaki gain tahunan, memperbolehkan penyesuaian cost-basis, atau menerapkan tarif berbeda untuk periode holding berbeda. Pakai tool untuk skenario perencanaan, bukan untuk filing pajak. Field pajak opsional; atur ke 0% untuk akun yang di-tax-advantage (401k, Roth IRA, Reksa Dana Indonesia)."},{"question":"Apa beda frekuensi compounding?","answer":"Frekuensi compounding mengontrol seberapa sering bunga ditambahkan ke saldo. Bulanan berarti bunga dihitung 12 kali per tahun, kuartalan 4 kali, semi-tahunan 2 kali, tahunan sekali. Compounding lebih sering menghasilkan nilai akhir sedikit lebih tinggi karena bunga menghasilkan bunga lebih cepat. Untuk tarif 6% tahunan selama 20 tahun pada Rp 10 juta tanpa setoran: compounding bulanan memberi Rp 33,1 juta, kuartalan memberi Rp 32,9 juta, tahunan memberi Rp 32,1 juta. Bedanya kecil untuk tarif rendah dan periode pendek, lebih besar untuk tarif tinggi selama dekade.

ROT13 shifts each letter 13 positions in the alphabet — a becomes n, b becomes o, and so on. Because 13 is exactly half of 26, applying ROT13 twice returns the original (it is its own inverse). It is commonly used on Usenet and in puzzle contexts to hide spoilers, punchlines, or off-topic jokes from casual readers. It provides zero security — any 5-year-old with frequency analysis can break it. Do not use it for anything you actually need to keep secret; use AES or similar for that."},{"question":"What does \"process each line separately\" do?","answer":"It splits the input on newlines, applies the transformation to each line independently, and joins the results with newlines. Without it, the transform is applied to the whole input as a single string, which means reverse-lines would just reverse the line order (useful) but reverse-chars would also reverse the newlines (the entire text including line breaks becomes one reversed block). With \"separate\" on, you can ROT13 or flip each line individually — handy for batch processing a list of pre-formatted strings, CSV cells, or log lines."},{"question":"How does the swap button work?","answer":"Swap moves the current output to the input box and the previous input to the output box, then re-runs the transformation. The counts and toast update. Use it to chain transforms: reverse chars → swap → ROT13 → swap → reverse words. Or to keep applying different transforms iteratively to the same source text. The state is not saved across page reloads — the input and output revert to whatever you last typed in the input field, and output regenerates on the next render."},{"question":"Is my text private?","answer":"Yes. All six transforms are pure string functions inlined in the HTML. There are no network calls, no API lookups, no CDN scripts. The Unicode flip table is a static object literal in the source. You can flip secret messages, encode spoilers, or test ROT13 puzzles without any data being transmitted."}],"faq_id":[{"question":"Bagaimana kerja teks upside-down sebenarnya?","answer":"Ia memakai karakter Unicode yang secara visual mirror dari padanan Latin-nya. a → ɐ (U+0250), b → q (U+0071 dalam konteks ini), c → ɔ (U+0254), d → p (U+0070), dan seterusnya. Tabel lengkap mencakup a-z huruf kecil, A-Z huruf besar, digit 0-9, dan tanda baca umum seperti kurung, bracket, tanda seru dan tanya. Setelah flipping, hasilnya di-reverse karakternya supaya karakter terakhir jadi pertama, yang diharapkan mata untuk teks upside-down. Karakter yang tidak dalam tabel (emoji, CJK, Latin beraksen) lewat tanpa berubah, jadi output bisa terlihat campuran."},{"question":"Apakah ROT13 cipher sungguhan?","answer":"Ya, tapi sangat lemah. ROT13 menggeser tiap huruf 13 posisi dalam alfabet — a menjadi n, b menjadi o, dan seterusnya. Karena 13 persis setengah dari 26, menerapkan ROT13 dua kali mengembalikan asli (ia inversi sendiri). Umumnya dipakai di Usenet dan dalam konteks puzzle untuk menyembunyikan spoiler, punchline, atau jokes off-topic dari pembaca kasual. Memberi keamanan nol — siapa pun dengan frequency analysis bisa memecahkannya. Jangan pakai untuk apa pun yang benar-benar perlu kamu rahasiakan; pakai AES atau semacamnya untuk itu."},{"question":"Apa yang dilakukan \"proses tiap baris terpisah\"?","answer":"Ia memisahkan input pada newline, menerapkan transformasi ke tiap baris secara independen, dan menggabungkan hasil dengan newline. Tanpanya, transform diterapkan ke seluruh input sebagai string tunggal, yang berarti reverse-karakter juga akan me-reverse newline (seluruh teks termasuk line break menjadi satu blok terbalik). Dengan \"terpisah\" aktif, kamu bisa ROT13 atau flip tiap baris secara individual — berguna untuk pemrosesan batch daftar string terformat, sel CSV, atau baris log."},{"question":"Bagaimana kerja tombol swap?","answer":"Swap memindahkan output saat ini ke kotak input dan input sebelumnya ke kotak output, lalu menjalankan ulang transformasi. Counter dan toast update. Pakai untuk merangkai transform: reverse karakter → swap → ROT13 → swap → reverse kata. Atau untuk terus menerapkan transform berbeda secara iteratif ke teks sumber yang sama. State tidak disimpan antar reload halaman — input dan output kembali ke apa pun yang terakhir kamu ketik di field input, dan output di-generate ulang di render berikutnya."},{"question":"Apakah teks saya privat?","answer":"Ya. Keenam transform adalah fungsi string murni yang di-inline di HTML. Tidak ada panggilan jaringan, tidak ada lookup API, tidak ada script CDN. Tabel flip Unicode adalah literal objek statis di source. Kamu bisa flip pesan rahasia, encode spoiler, atau test puzzle ROT13 tanpa data apa pun yang ditransmisikan."}]},{"id":"5c4ae3c2-2edc-4f1e-ac15-b8fe71a01fdc","slug":"svg-optimizer","name":"SVG Optimizer","name_id":"Optimasi SVG","icon":"🎨","category":"developer","meta_description":"Minify SVG by stripping comments, metadata, hidden elements, empty groups, whitespace, unused IDs.

It does not change path data, colors, or transforms. The one option with a visible effect is \"Round decimals (2)\" which truncates coordinate precision — for most icons and logos 2 decimal places is more than enough (the difference is sub-pixel), but for extremely large or high-resolution SVGs you may want to keep 3 or 4 decimals to avoid precision artifacts."},{"question":"Why are unused IDs removed?","answer":"Many design tools (Figma, Illustrator, Sketch, Inkscape) auto-generate id=\"layer_42\" type attributes for every shape, even when nothing references them. Keeping them just inflates the file. The tool scans for url(#id), xlink:href=\"#id\", and href=\"#id\" references and removes any id attribute that is not referenced. Be careful: if you embed the SVG inline in HTML and use CSS like #my-logo { ... } to style it from outside, that id WILL be referenced (via the CSS selector) but the optimizer cannot see that. In that case, turn off \"Strip unused IDs\"."},{"question":"Does this support SVGs with embedded styles or scripts?","answer":"It removes <style> blocks only via the metadata strip if you have it on — and only if the style tag is wrapped in <metadata>. Inline style attributes (style=\"fill:red\") are kept. <script> blocks are kept as-is. If your SVG has animation (<animate>, <animateTransform>, <animateMotion>) those are kept too, and the optimizer will not touch their attribute values. Use the optimizer for static icons and illustrations; for complex animated SVGs, the savings will be smaller and you may want to keep the metadata."},{"question":"What does the preview box show?","answer":"The preview box renders the optimized SVG using the standard browser SVG renderer. If the source has viewBox=\"0 0 24 24\" and width=\"24\" height=\"24\", the preview shows it scaled to fit 160x160. If the source has no width/height, the optimizer does not add them — the browser will fall back to the viewBox or to 300x150 default. The viewBox is read from the source and shown in the card title as \"viewBox: 0 0 X Y\" so you can verify the optimizer did not mangle the coordinate system."},{"question":"Is my SVG private?","answer":"Yes. The optimizer is pure client-side JavaScript inlined in the HTML. There are no network calls, no API uploads, no CDN. The file you drop or paste stays in your browser. The downloaded result lands in your local Downloads folder. You can optimize proprietary SVGs, customer logos, or internal iconography without any data being transmitted.

Ia tidak mengubah data path, warna, atau transform. Satu-satunya opsi dengan efek terlihat adalah \"Bulatkan desimal (2)\" yang memotong presisi koordinat — untuk kebanyakan icon dan logo 2 tempat desimal sudah lebih dari cukup (bedanya sub-pixel), tapi untuk SVG yang sangat besar atau resolusi tinggi kamu mungkin ingin mempertahankan 3 atau 4 desimal untuk menghindari artefak presisi."},{"question":"Kenapa ID tak terpakai dihapus?","answer":"Banyak tool desain (Figma, Illustrator, Sketch, Inkscape) auto-generate atribut id=\"layer_42\" untuk tiap shape, bahkan ketika tidak ada yang mereferensikannya. Mempertahankan mereka hanya membengkakkan file. Tool memindai referensi url(#id), xlink:href=\"#id\", dan href=\"#id\" dan menghapus atribut id apa pun yang tidak direferensikan. Hati-hati: kalau kamu embed SVG inline di HTML dan memakai CSS seperti #my-logo { ... } untuk men-style-nya dari luar, id itu AKAN direferensikan (via selector CSS) tapi optimizer tidak bisa melihat itu. Dalam kasus itu, matikan \"Hapus ID tak terpakai\"."},{"question":"Apakah ini mendukung SVG dengan style atau script tertanam?","answer":"Ia menghapus blok <style> hanya via strip metadata kalau kamu mengaktifkannya — dan hanya kalau tag style dibungkus dalam <metadata>. Atribut style inline (style=\"fill:red\") dipertahankan. Blok <script> dipertahankan apa adanya. Kalau SVG kamu punya animasi (<animate>, <animateTransform>, <animateMotion>) itu juga dipertahankan, dan optimizer tidak akan menyentuh nilai atributnya.

This is what vehicle loans (KKB) and most pinjol (online loans) use, and the total interest over the loan is easy to predict. Effective (anuitas) interest calculates interest on the outstanding principal each month: as you pay down the loan, the interest portion shrinks and the principal portion grows. The monthly payment stays the same but the split changes. This is what mortgages (KPR) and most consumer loans at banks use. On a Rp 500M loan at 10% over 20 years, flat gives you a total interest of about Rp 500M, while effective gives you about Rp 632M — a big difference, which is why flat is sometimes marketed as \"cheaper\" even though the total cost is the same in absolute terms."},{"question":"Why does my amortization table end early when I add an extra payment?","answer":"When you enter an \"extra monthly payment\" and a month limit, the simulation adds that amount to every payment up to that month. This pays off the principal faster, so the loan reaches zero balance before the original tenor. The tool then truncates the table at the actual payoff month and shows a \"savings\" banner with the number of months and total interest you saved compared to the no-extra-payment baseline. Be careful: in the flat method, the interest portion of each payment is fixed regardless of how much principal is left, so adding extra only shortens the principal portion. In the effective method, the extra goes 100% to principal, which is what you want."},{"question":"Does this include fees, taxes, or insurance?","answer":"No. The tool works on principal, interest, and tenor only. It does not add admin fees, provision fees, insurance premiums, notarial fees, or any other charges that Indonesian lenders typically bundle. For KPR, ask your bank for the \"effective rate\" (suku bunga efektif) which already includes some of these — or compute the all-in cost yourself by adding the total fees to the principal in the input. The amortization table itself is mathematically exact for the inputs you give it, but the actual monthly debit from your account will usually be higher than the \"cicilan\" shown here."},{"question":"Can I export the amortization table to a spreadsheet?","answer":"Yes. The \"Export CSV\" button downloads loan-amortization.csv with the month number, date, payment, principal, interest, and balance columns. Open it in Excel, Google Sheets, or Numbers. The currency is plain decimal (not formatted with Rp/USD prefix) so spreadsheet apps recognize it as a number. Dates are ISO 8601 (YYYY-MM-DD) so they sort correctly.

Ini yang dipakai kredit kendaraan (KKB) dan kebanyakan pinjol, dan total bunga sepanjang pinjaman mudah diprediksi. Bunga efektif (anuitas) menghitung bunga dari sisa pokok tiap bulan: begitu kamu membayar pokok, porsi bunga mengecil dan porsi pokok membesar. Cicilan tetap tapi split berubah. Ini yang dipakai KPR (Kredit Pemilikan Rumah) dan kebanyakan kredit konsumen di bank. Pada pinjaman Rp 500jt di 10% selama 20 tahun, flat memberi total bunga sekitar Rp 500jt, sedangkan efektif memberi sekitar Rp 632jt — beda besar, itulah kenapa flat kadang dipasarkan sebagai \"lebih murah\" padahal biaya total absolutnya kurang lebih sama."},{"question":"Kenapa tabel amortisasi saya berakhir lebih awal ketika saya tambah bayar lebih?","answer":"Ketika kamu masukkan \"bayar tambahan per bulan\" dan batas bulan, simulasi menambahkan jumlah itu ke tiap cicilan sampai bulan tersebut. Ini melunasi pokok lebih cepat, jadi pinjaman mencapai saldo nol sebelum tenor asli. Tool lalu memotong tabel di bulan pelunasan aktual dan menampilkan banner \"hemat\" dengan jumlah bulan dan total bunga yang dihemat dibanding baseline tanpa bayar tambahan. Hati-hati: di metode flat, porsi bunga tiap cicilan tetap terlepas dari sisa pokok, jadi tambahan hanya mempersingkat porsi pokok. Di metode efektif, tambahan 100% masuk ke pokok, yang kamu inginkan."},{"question":"Apakah ini termasuk biaya, pajak, atau asuransi?","answer":"Tidak. Tool bekerja pada pokok, bunga, dan tenor saja. Tidak menambahkan biaya admin, biaya provisi, premi asuransi, biaya notaris, atau charges lain yang biasanya dibundle lender Indonesia. Untuk KPR, tanyakan ke bank kamu \"suku bunga efektif\" yang sudah mencakup beberapa dari ini — atau hitung all-in cost sendiri dengan menambahkan total fee ke pokok di input.

Stocks historically return 8-11% nominal long-term, government bonds 6-7%, time deposits 4-5%. A 60/30/10 stock/bond/deposit mix might yield 7-8% nominal. Be conservative: if you assume 12% and only get 7%, your projection is off by 40%. Inflation in Indonesia has averaged 4-6% over the past two decades, so 4% is a reasonable forward assumption. If you want a stress test, run the calculator with 4% return and 6% inflation and see whether you are still on track."},{"question":"Why is the \"real value\" lower than the nominal fund?","answer":"Inflation. The nominal fund is the raw future-value calculation: how much money you would have in nominal rupiah (or dollars) at retirement. The real value is what that money is worth in today's purchasing power. If you retire in 25 years with Rp 5 billion nominal and average inflation is 4%, the real value is roughly Rp 5B / (1.04)^25 ≈ Rp 1.87B. So you have Rp 5B on paper but it buys what Rp 1.87B buys today. The shortfall/surplus is calculated on the real value, because that is what determines whether you can actually maintain your desired lifestyle. The target needed is also in today's money, which is why the income you enter should be \"in today's value\" — the tool inflates it implicitly through the real return calculation."},{"question":"How is \"needed fund\" calculated?","answer":"The needed fund is the present value (in today's money) of the annuity you would draw down during retirement, assuming the same real return rate (nominal return minus inflation, compounded). If you want Rp 15M per month for 25 years of retirement and the real return is 4% annual (which compounds to about 0.33% monthly), the formula is: needed = 15M * (1 - (1.0033)^-300) / 0.0033 ≈ Rp 2.6B in today's money. If the real return is zero or negative, the formula simplifies to income * months. This is the standard annuity-present-value formula used in financial planning, and it assumes you draw down the fund to zero by the end of your life expectancy (a common assumption — you can adjust by entering a higher life expectancy or longer retirement horizon to leave a bequest)."},{"question":"What if the recommended monthly deposit is much higher than what I can afford?","answer":"The tool gives you a math-optimal answer, not a budget answer. If the recommended deposit is 2x what you can afford, you have three options: (1) push your retirement age out (each extra year compounds massively), (2) lower your desired retirement income (a 20% reduction in target income cuts the needed fund by ~25% in present value terms), or (3) increase your expected return (risky — that is a market bet, not a guarantee). The danger advice (\"Target tidak realistis di Y tahun\") fires when the required monthly exceeds 5x your current contribution; that is usually a sign you need to either delay retirement significantly or accept a lower lifestyle."},{"question":"Is my financial data private?","answer":"Yes. The retirement calculator is pure client-side JavaScript inlined in the HTML. There are no network calls, no API uploads, no analytics, no CDN. Your age, current savings, monthly contribution, and expected return stay in your browser. The chart is generated inline as an SVG.

Saham historis return 8-11% nominal jangka panjang, obligasi pemerintah 6-7%, deposito 4-5%. Campuran 60/30/10 saham/obligasi/deposito mungkin memberi 7-8% nominal. Konservatiflah: kalau kamu asumsikan 12% dan hanya dapat 7%, proyeksi kamu meleset 40%. Inflasi di Indonesia rata-rata 4-6% selama dua dekade terakhir, jadi 4% adalah asumsi maju yang masuk akal. Kalau mau stress test, jalankan kalkulator dengan return 4% dan inflasi 6% dan lihat apakah kamu masih di jalur."},{"question":"Kenapa \"nilai riil\" lebih rendah dari dana nominal?","answer":"Inflasi. Dana nominal adalah kalkulasi nilai masa depan mentah: berapa banyak uang yang kamu punya dalam rupiah (atau dolar) nominal saat pensiun. Nilai riil adalah apa yang uang itu beli dalam daya beli hari ini. Kalau kamu pensiun 25 tahun dari sekarang dengan Rp 5 miliar nominal dan inflasi rata-rata 4%, nilai riilnya kira-kira Rp 5M / (1.04)^25 ≈ Rp 1.87M. Jadi kamu punya Rp 5M di atas kertas tapi itu membeli apa yang Rp 1.87M beli hari ini. Kurang/lebih dihitung pada nilai riil, karena itu yang menentukan apakah kamu bisa mempertahankan gaya hidup yang diinginkan. Target dibutuhkan juga dalam uang hari ini, itulah kenapa income yang kamu masukkan harus \"dalam nilai saat ini\" — tool meng-inflate-kan secara implisit melalui kalkulasi return riil."},{"question":"Bagaimana \"dana dibutuhkan\" dihitung?","answer":"Dana dibutuhkan adalah present value (dalam uang hari ini) dari annuity yang akan kamu tarik selama pensiun, dengan asumsi tingkat return riil yang sama (return nominal dikurangi inflasi, dimajemukkan). Kalau kamu mau Rp 15jt per bulan selama 25 tahun pensiun dan return riil 4% tahunan (yang menjadi sekitar 0.33% bulanan), formula: dibutuhkan = 15jt * (1 - (1.0033)^-300) / 0.0033 ≈ Rp 2.6M dalam uang hari ini. Kalau return riil nol atau negatif, formula menyederhanakan ke income * bulan. Ini adalah formula annuity-present-value standar yang dipakai dalam perencanaan keuangan, dan mengasumsikan kamu menarik dana ke nol di akhir harapan hidup (asumsi umum — kamu bisa menyesuaikan dengan memasukkan harapan hidup lebih tinggi atau horizon pensiun lebih panjang untuk meninggalkan warisan)."},{"question":"Bagaimana kalau rekomendasi setoran bulanan jauh lebih tinggi dari yang saya mampu?","answer":"Tool memberi jawaban optimal secara matematika, bukan jawaban budget. Kalau setoran yang direkomendasikan 2x dari yang kamu mampu, ada tiga opsi: (1) dorong usia pensiun ke luar (tiap tahun ekstra memajemukkan secara masif), (2) turunkan income pensiun yang diinginkan (pengurangan 20% pada target income memotong dana dibutuhkan ~25% dalam present value), atau (3) naikkan expected return (berisiko — itu pasar taruhan, bukan jaminan). Saran bahaya (\"Target tidak realistis di Y tahun\") muncul ketika setoran yang diperlukan melebihi 5x setoran kamu saat ini; biasanya itu pertanda kamu perlu menunda pensiun secara signifikan atau menerima gaya hidup lebih rendah."},{"question":"Apakah data keuangan saya privat?","answer":"Ya.

For each criterion, you also assign a weight from 1 to 10 that reflects how much that criterion matters to you. The tool multiplies the score by the weight for every cell, then sums those products to give the option's total. So if Option A scores 8/10 on Salary (weight 9) and 5/10 on Commute (weight 3), its weighted contribution from those two criteria is (8*9) + (5*3) = 87. The total is summed across all criteria, then the options are sorted by total descending. The top three get gold/silver/bronze styling, and the top option is shown as the recommendation in the winner card. The math is intentionally simple and transparent — there is no fuzzy logic, no hidden normalization, no surprise weighting."},{"question":"How should I choose the weights?","answer":"The weights are the most subjective part of the matrix and that is the point. A common approach is \"must-have vs nice-to-have\": if a criterion is essential (e.g. salary must cover your rent), give it a high weight (8-10). If it is a tie-breaker (e.g. free coffee), give it a low weight (1-3). Another approach is \"comparative weighting\": if Salary matters twice as much as Commute to you, set Salary weight = 8 and Commute weight = 4 (or 6 and 3, or 10 and 5 — any consistent ratio). The absolute scale (1-10) does not matter as much as the relative ratios between criteria. After you build the matrix, try flipping one weight from 5 to 9 and see if the winner changes — if not, the criterion is not actually doing work and you can drop it."},{"question":"What does the \"Saved Decisions\" list do?","answer":"Every time you click Export JSON, a snapshot of the current matrix (options, criteria, scores, weights) is saved to localStorage under the key decision-matrix-saved as a JSON array, max 10 entries. The \"Saved Decisions\" card at the bottom shows these snapshots with their name (auto-generated from the option names), timestamp, and a Load / Delete button pair. Load replaces the current matrix with the saved one. Delete removes it from the list. The list is local to this browser — it does not sync anywhere. If you want a permanent backup, use Export JSON and save the file to your device or cloud storage; you can re-import it later with the Import button."},{"question":"Can I compare more than 10 options or 10 criteria?","answer":"Technically yes, the tool will accept any number of options and criteria. Practically, the matrix becomes hard to read beyond 5-6 options (the table is wide on mobile) and beyond 5-6 criteria (you start losing the ability to differentiate scores consistently). For larger comparisons, consider grouping criteria into categories (e.g. \"Financial\" weight = sum of 3 sub-criteria, \"Lifestyle\" weight = sum of 3 sub-criteria) and running the matrix at the category level. Or build multiple matrices — one for \"must-haves\" filter, one for \"trade-off comparison\" — and combine the conclusions."},{"question":"Is my decision data private?","answer":"Yes. The matrix is pure client-side JavaScript inlined in the HTML. There are no network calls, no API uploads, no analytics, no CDN.

Untuk tiap kriteria, kamu juga assign bobot 1 sampai 10 yang mencerminkan seberapa penting kriteria itu buat kamu. Tool mengalikan nilai dengan bobot untuk setiap cell, lalu menjumlahkan produk itu untuk memberikan total opsi. Jadi kalau Opsi A nilai 8/10 di Gaji (bobot 9) dan 5/10 di Commute (bobot 3), kontribusi tertimbangnya dari dua kriteria itu adalah (8*9) + (5*3) = 87. Total dijumlahkan lintas semua kriteria, lalu opsi diurutkan berdasarkan total descending. Tiga teratas mendapat style emas/perak/perunggu, dan opsi teratas ditampilkan sebagai rekomendasi di kartu pemenang. Matematikanya sengaja sederhana dan transparan — tidak ada logika fuzzy, tidak ada normalisasi tersembunyi, tidak ada bobot kejutan."},{"question":"Bagaimana cara memilih bobot?","answer":"Bobot adalah bagian paling subjektif dari matriks dan justru itu intinya. Pendekatan umum adalah \"wajib vs nice-to-have\": kalau kriteria esensial (mis. gaji harus覆盖 sewa), berikan bobot tinggi (8-10). Kalau itu tie-breaker (mis. kopi gratis), berikan bobot rendah (1-3). Pendekatan lain adalah \"pembobotan komparatif\": kalau Gaji 2x lebih penting dari Commute buat kamu, set bobot Gaji = 8 dan Commute = 4 (atau 6 dan 3, atau 10 dan 5 — rasio konsisten apa pun). Skala absolut (1-10) tidak sepenting rasio relatif antar kriteria. Setelah kamu bangun matriksnya, coba balik satu bobot dari 5 ke 9 dan lihat apakah pemenangnya berubah — kalau tidak, kriteria itu sebenarnya tidak bekerja dan kamu bisa drop."},{"question":"Apa yang dilakukan daftar \"Keputusan Tersimpan\"?","answer":"Tiap kali kamu klik Export JSON, snapshot matriks saat itu (opsi, kriteria, nilai, bobot) disimpan ke localStorage dengan key decision-matrix-saved sebagai array JSON, max 10 entri. Kartu \"Keputusan Tersimpan\" di bawah menampilkan snapshot ini dengan namanya (auto-generated dari nama opsi), timestamp, dan pasangan tombol Muat / Hapus.

Praktiknya, matriks jadi sulit dibaca di atas 5-6 opsi (tabel lebar di mobile) dan di atas 5-6 kriteria (kamu mulai kehilangan kemampuan untuk membedakan nilai secara konsisten). Untuk perbandingan lebih besar, pertimbangkan mengelompokkan kriteria ke kategori (mis. \"Finansial\" bobot = jumlah 3 sub-kriteria, \"Gaya Hidup\" bobot = jumlah 3 sub-kriteria) dan jalankan matriks di level kategori. Atau bangun beberapa matriks — satu untuk filter \"wajib\", satu untuk \"trade-off\" — dan gabungkan kesimpulannya."},{"question":"Apakah data keputusan saya privat?","answer":"Ya.

With only 25 possible keys, an attacker can try all of them in microseconds. This tool is for education, puzzles, and fun, not for protecting secrets. The brute force mode demonstrates this: it scores all 26 candidates and highlights the most likely plaintext. If you need real confidentiality, use AES-256 (a modern symmetric cipher) or X25519 + ChaCha20 (for key exchange + encryption). The Caesar cipher is historically interesting because it was used by Julius Caesar around 50 BC for military messages, and it illustrates the basic idea of substitution ciphers — every letter is replaced by another letter at a fixed offset."},{"question":"What is ROT13?","answer":"ROT13 is Caesar cipher with shift 13. The special property of shift 13 is that applying it twice returns the original text: ROT13(ROT13(x)) = x. This is because the English alphabet has 26 letters and 13 is exactly half of 26, so each letter maps to the letter 13 positions away, and mapping 13 positions away from that letter brings you back to the start. ROT13 is widely used online to obscure spoilers, puzzle answers, NSFW content, and mildly offensive jokes — anyone who wants to read the text can apply ROT13 in their head (or with a tool like this) and the original content is hidden from casual scanning. It is not encryption because there is no key — the shift is always 13."},{"question":"What does the brute force star marker mean?","answer":"The brute force mode runs all 26 shifts on your cipher text and scores each candidate plaintext by counting how many of the words match a small built-in list of ~100 common English words (\"the\", \"and\", \"to\", \"of\", \"is\", \"are\", etc.). The shift with the highest score gets a star marker. If your cipher text is short (under 30 characters) or contains mostly proper nouns / unusual words, the star may be wrong — common words are a heuristic, not a guarantee. Read each candidate by eye, and use the star as a hint, not a definitive answer. You can also use the copy button next to each candidate to grab that particular shift's output."},{"question":"What charset should I pick?","answer":"Use \"A-Z case-preserved\" (default) for most English text. It shifts A→A+shift, B→B+shift, etc. while keeping the case of the original letter, and passes numbers, punctuation, and whitespace through unchanged. Use \"a-z only\" or \"A-Z only\" if you want strict single-case behavior (useful for some puzzle formats). Use \"Printable ASCII (32-126)\" if your text contains non-letter characters that you also want shifted — for example, if you have an obfuscated file path or a string of mixed letters and digits where you want everything shifted. Note that with the ASCII option, spaces and punctuation are also shifted, which can make the output harder to read."},{"question":"Is my text private?","answer":"Yes. The cipher is pure client-side JavaScript inlined in the HTML. There are no network calls, no API uploads, no analytics, no CDN. Your plaintext, cipher text, and chosen shift stay in your browser.

Dengan hanya 25 kunci yang mungkin, penyerang bisa mencoba semuanya dalam mikrodetik. Tool ini untuk edukasi, puzzle, dan kesenangan, bukan untuk melindungi rahasia. Mode brute force mendemonstrasikan ini: ia menilai 26 kandidat dan menyorot plaintext paling mungkin. Kalau kamu butuh kerahasiaan nyata, pakai AES-256 (sandi simetrik modern) atau X25519 + ChaCha20 (untuk pertukaran kunci + enkripsi). Sandi Caesar menarik secara historis karena dipakai Julius Caesar sekitar 50 SM untuk pesan militer, dan mengilustrasikan ide dasar sandi substitusi — tiap huruf diganti dengan huruf lain pada offset tetap."},{"question":"Apa itu ROT13?","answer":"ROT13 adalah sandi Caesar dengan shift 13. Properti khusus dari shift 13 adalah menerapkan dua kali mengembalikan teks asli: ROT13(ROT13(x)) = x. Ini karena alfabet Inggris punya 26 huruf dan 13 persis setengah dari 26, jadi tiap huruf memetakan ke huruf 13 posisi jauhnya, dan memetakan 13 posisi jauhnya dari huruf itu membawa kamu kembali ke awal. ROT13 banyak dipakai online untuk mengaburkan spoiler, jawaban puzzle, konten NSFW, dan joke yang agak ofensif — siapa pun yang mau membaca teks bisa menerapkan ROT13 di kepala mereka (atau dengan tool seperti ini) dan konten asli tersembunyi dari pemindaian kasual. Itu bukan enkripsi karena tidak ada kunci — shift selalu 13."},{"question":"Apa arti marker bintang brute force?","answer":"Mode brute force menjalankan 26 shift pada teks sandi kamu dan menilai tiap kandidat plaintext dengan menghitung berapa banyak kata yang cocok dengan daftar kecil built-in ~100 kata umum Inggris (\"the\", \"and\", \"to\", \"of\", \"is\", \"are\", dll.). Shift dengan skor tertinggi mendapat marker bintang. Kalau teks sandi kamu singkat (di bawah 30 karakter) atau mengandung banyak proper noun / kata tidak biasa, bintang mungkin salah — kata umum adalah heuristik, bukan jaminan.

(3) A frequency map counts how many pixels fall into each bucket, then the top 40 buckets are clustered with a 8-iteration K-means into the requested number of centroids. The K-means step merges over-represented buckets and splits under-represented ones to give an even palette. Finally, the percentage of each output color is the sum of pixels in the buckets that merged into its centroid. The whole pipeline runs in JS on the canvas pixel data, no WebAssembly, no network."},{"question":"What granularity should I pick?","answer":"It depends on the image. For photographs and complex gradients, 3-bit (medium, default) gives 5-10 distinct dominant colors with smooth transitions. For flat-design illustrations, posters, or logo art, 2-bit (low) gives a posterized palette of 3-6 strong colors. For detailed paintings or photos with many subtle hues, 4-bit (high) gives finer differentiation but may include near-duplicate colors. If the result looks \"too few\" colors, raise the granularity; if it looks \"too many similar\" colors, lower it. Also, more colors (the top selector) plus higher granularity is the most detailed; fewer colors plus lower granularity is the most abstracted. Try 3 colors at 2-bit for a Bauhaus look, or 10 colors at 4-bit for a full spectrum."},{"question":"How is the gradient rendered?","answer":"The preview uses a CSS linear-gradient or radial-gradient background, with one color stop per palette color, evenly distributed from 0% to 100% of the gradient. The \"Linear 90°\" option runs left-to-right (the default), \"45°\" runs bottom-left to top-right, \"180°\" runs bottom-to-top, and \"Radial\" uses a circle with the first color at the center and the last at the edge. The PNG download renders the same gradient to a 1200x480 canvas via canvas createLinearGradient / createRadialGradient, then exports as PNG with the standard toBlob. The CSS download saves a .css file with a .gradient class that you can paste into any project."},{"question":"Is my image private?","answer":"Yes.

(2) Nilai R, G, B tiap pixel di-kuantisasi dengan bit-shift (2-bit, 3-bit, atau 4-bit per channel) supaya warna serupa bergabung ke \"bucket\" — 2-bit memberi 64 bucket (8 per channel), 3-bit memberi 512, 4-bit memberi 4096. (3) Peta frekuensi menghitung berapa banyak pixel jatuh ke tiap bucket, lalu 40 bucket teratas di-cluster dengan 8-iterasi K-means ke jumlah centroid yang diminta. Langkah K-means menggabungkan bucket yang terlalu terwakili dan memecah yang kurang terwakili untuk memberikan palet yang merata. Akhirnya, persentase tiap warna output adalah jumlah pixel di bucket yang bergabung ke centroid-nya. Seluruh pipeline berjalan di JS pada data pixel canvas, tanpa WebAssembly, tanpa jaringan."},{"question":"Granularitas mana yang harus saya pilih?","answer":"Tergantung gambar. Untuk foto dan gradient kompleks, 3-bit (sedang, default) memberi 5-10 warna dominan berbeda dengan transisi halus. Untuk ilustrasi flat-design, poster, atau seni logo, 2-bit (rendah) memberi palet ter-posterisasi 3-6 warna kuat. Untuk lukisan detail atau foto dengan banyak nuansa halus, 4-bit (tinggi) memberi differensiasi lebih halus tapi mungkin termasuk warna near-duplikat. Kalau hasilnya terlihat \"terlalu sedikit\" warna, naikkan granularitas; kalau terlihat \"terlalu banyak serupa\" warna, turunkan. Juga, lebih banyak warna (selector atas) plus granularitas lebih tinggi adalah yang paling detail; lebih sedikit warna plus granularitas lebih rendah adalah yang paling diabstraksi. Coba 3 warna di 2-bit untuk tampilan Bauhaus, atau 10 warna di 4-bit untuk spektrum penuh."},{"question":"Bagaimana gradient di-render?","answer":"Preview memakai background CSS linear-gradient atau radial-gradient, dengan satu color stop per warna palet, didistribusikan merata dari 0% ke 100% gradient. Opsi \"Linear 90°\" berjalan kiri-ke-kanan (default), \"45°\" berjalan dari kiri-bawah ke kanan-atas, \"180°\" berjalan dari bawah-ke-atas, dan \"Radial\" menggunakan circle dengan warna pertama di tengah dan terakhir di tepi. Download PNG me-render gradient yang sama ke canvas 1200x480 via canvas createLinearGradient / createRadialGradient, lalu export sebagai PNG dengan toBlob standar. Download CSS menyimpan file .css dengan class .gradient yang bisa kamu paste ke proyek mana pun."},{"question":"Apakah gambar saya privat?","answer":"Ya. Ekstraktor adalah JavaScript murni sisi client yang di-inline di HTML. Tidak ada panggilan jaringan, tidak ada upload API, tidak ada analitik, tidak ada CDN. Gambar kamu dimuat via FileReader (yang membaca file dari disk lokal kamu) dan digambar ke canvas tersembunyi, lalu data pixel diproses lokal. Salinan yang di-downscale, palet, gradient, dan PNG yang di-export semua di-generate di browser. Kamu bisa ekstrak warna dari foto privat, logo pelanggan, atau gambar produk proprietary tanpa data apa pun yang ditransmisikan. Satu-satunya operasi file adalah FileReader untuk drop-zone dan <a download> standar untuk export CSS/PNG."},{"question":"Bisakah saya ekstrak warna dari URL?","answer":"Tidak, tool hanya menerima file lokal via file picker atau drag-and-drop. Menambah loading berbasis URL akan memerlukan fetch gambar dari server remote, yang akan membocorkan URL (dan parameter path atau query image sensitif) ke proxy CORS atau host image apa pun yang menyediakannya. Desain privasi-utama adalah disengaja: gambar tidak pernah meninggalkan device kamu. Kalau kamu punya gambar di URL yang ingin kamu proses, download dulu (klik-kanan → Save As, atau pakai download manager), lalu drop file lokal ke tool. Tool juga menerima format gambar apa pun yang bisa di-decode browser — PNG, JPG, WebP, GIF, BMP, ICO, AVIF (di browser yang didukung) — jadi workflow lokal fleksibel."}]},{"id":"49516679-6197-4f3d-8396-f3f6db2784da","slug":"rangkuman-bodo-amat","name":"Rangkuman Bodo Amat (The Subtle Art of Not Giving a F*ck)","name_id":"Rangkuman Bodo Amat","icon":"📖","category":"reading","meta_description":"Complete summary of Mark Manson's \"The Subtle Art of Not Giving a F*ck\" in Indonesian. 9 BAB, 39 sub-bab, expandable accordion. 100% offline.","meta_description_id":"Rangkuman lengkap buku \"The Subtle Art of Not Giving a F*ck\" karya Mark Manson dalam Bahasa Indonesia. 9 BAB, 39 sub-bab, accordion yang bisa dibuka-tutup. 100% offline.","long_description":"Rangkuman lengkap buku \"The Subtle Art of Not Giving a F*ck\" (terjemahan Bahasa Indonesia: \"Bodo Amat\") karya Mark Manson.

The summary captures the main ideas, frameworks, and examples of each BAB and sub-bab, but does not include every paragraph, story, or footnote. For the full experience, read the actual book. The summary works best as a refresher, study reference, or a way to decide if you want to read the book in full."},{"question":"Why is it called \"Bodo Amat\"?","answer":"\"Bodo Amat\" is the Indonesian translation of the book's original title \"The Subtle Art of Not Giving a F*ck\". The phrase is used informally in Indonesian to express that something is \"not a big deal\" or \"who cares\" - a healthy reframe from giving too much attention to things that do not matter. The translation was chosen for its punch and because it captures the spirit of the book in a way that feels native to Indonesian readers."},{"question":"Who should read this summary?","answer":"Anyone curious about the book's ideas but not ready to commit to a full read, anyone who has read it before and wants a quick refresher, or anyone interested in self-help and mindset frameworks but prefers condensed practical content over 200+ pages."},{"question":"How is the content organized?","answer":"The summary follows the book's structure: a Pengantar (introduction) plus 9 BAB (chapters), each divided into sub-bab (sub-chapters).
