bisa versus dapat versus mampu | Indonesian Grammar

Choose bisa for everyday skill and practical feasibility, dapat for formal possibility or the separate lexical meaning “obtain/receive,” and mampu when the issue is a person’s or institution’s underlying physical, mental, technical, or financial capacity. The three forms overlap, but they do not differ only in style: they highlight different sources of possibility.

English can hides several questions. Does the subject know how? Do circumstances allow it? Does a rule permit it? Does the subject have enough resources? Indonesian often answers those questions through its modal choice. This page guides that choice without giving exhaustive paradigms or sociolinguistic histories; the modal-order guide explains how these words combine with aspect and negation.

The quick decision

Question	Choose	Core idea
Can someone do this in ordinary life?	bisa	skill or practical feasibility
Is a formal text stating that something is possible or available?	dapat	formal-neutral possibility
Does the subject possess enough strength, expertise, money, or institutional resources?	mampu	underlying capacity
Does dapat have a noun object?	lexical mendapat/mendapatkan or conversational dapat	obtain/receive, not modal possibility
Are you asking permission?	bisa for workable polite request; boleh for permission itself	feasibility versus authorization

Nadia bisa menjahit kancing tanpa bantuan.

Nadia can sew on a button without help. (everyday learned skill)

Dokumen digital dapat diunduh melalui portal resmi.

The digital document can be downloaded through the official portal. (formal possibility)

Koperasi itu mampu membayar seluruh pinjamannya tepat waktu.

That cooperative is capable of repaying all its loans on time. (financial capacity)

💡

Ask what makes the event possible: ordinary skill or circumstances suggest bisa; formal availability suggests dapat; internal resources suggest mampu.

Bisa: the everyday default

Bisa + predicate is the broad conversational choice for learned ability, temporary ability, feasibility, and possible outcomes (neutral/informal).

Learned skill

Anak saya sudah bisa membaca jam analog.

My child can now read an analog clock. (acquired skill)

Rafi bisa memperbaiki sepeda, tetapi belum bisa memperbaiki mesin mobil.

Rafi can repair bicycles but cannot repair car engines yet. (differentiated skill)

Kamu bisa mengucapkan nama tempat itu dengan benar?

Can you pronounce that place name correctly? (ordinary ability question)

Circumstantial feasibility

Kalau lewat jalan belakang, kita bisa tiba sebelum toko tutup.

If we take the back road, we can arrive before the shop closes. (circumstantial possibility)

Meja ini bisa dilipat supaya muat di dalam mobil.

This table can be folded so it fits in the car. (physical feasibility)

Dengan tiket yang sama, penumpang bisa berganti bus satu kali.

With the same ticket, passengers can change buses once. (practical authorization/feasibility)

The table has no skill; the route and ticket create possibilities. That breadth makes bisa the best unmarked first choice in ordinary speech.

Polite service questions

In questions, bisa often packages a request as practical feasibility rather than confronting the listener with a direct demand.

Bisa saya bantu mencari ukuran yang lebih kecil?

Can I help you find a smaller size? (polite service question)

Bisa pembayarannya dilakukan setelah barang tiba?

Could payment be made after the item arrives? (polite feasibility question)

Bisa tolong periksa nomor reservasi saya sekali lagi?

Could you please check my reservation number once more? (polite service request)

Bisa kami duduk di dekat jendela kalau mejanya masih tersedia?

Could we sit near the window if the table is still available? (polite restaurant request)

Boleh asks authorization more directly: Boleh kami duduk di dekat jendela? “May we sit near the window?” Bisa leaves room for the answer “permitted, but no table is available.”

Dapat: formal possibility

Modal dapat + predicate commonly appears in instructions, legal or administrative notices, academic prose, and careful explanations (formal/neutral written). It often corresponds to English “can,” “may,” or “is able to,” but its discourse voice is more institutional than ordinary bisa.

Setiap warga negara dapat mengajukan permohonan sesuai dengan ketentuan yang berlaku.

Every citizen may submit an application in accordance with the applicable provisions. (formal legal notice)

Informasi lebih lanjut dapat diperoleh di kantor pelayanan terpadu.

Further information can be obtained at the integrated service office. (formal public notice)

Hasil penelitian ini dapat digunakan sebagai dasar evaluasi kebijakan.

The results of this study can be used as a basis for policy evaluation. (academic)

Pintu darurat hanya dapat dibuka dari dalam gedung.

The emergency door can only be opened from inside the building. (formal safety notice)

Peserta yang memenuhi syarat dapat mengikuti tahap seleksi berikutnya.

Eligible participants may take part in the next selection stage. (formal administrative)

In everyday speech, bisa is usually more natural:

Kamu bisa cek hasilnya lewat aplikasi nanti malam.

You can check the result through the app tonight. (informal/neutral conversation)

Hasilnya dapat diperiksa melalui aplikasi mulai pukul delapan malam.

The result can be checked through the application from eight in the evening. (formal announcement)

This is a register contrast, but not merely one. Dapat also has a separate lexical family.

Dapat as obtain or receive

Lexical dapat also means “get/obtain,” especially in casual speech, while prefixed mendapat and mendapatkan are common across neutral and formal usage. A following noun phrase is a strong clue that this is a lexical verb rather than a modal.

Tadi saya dapat pesan dari kantor cabang.

I got a message from the branch office earlier. (informal lexical dapat)

Setiap pemenang mendapat sertifikat dan hadiah berupa buku.

Each winner receives a certificate and a book as a prize. (neutral lexical mendapat)

Kami akhirnya mendapatkan izin untuk memperbaiki bangunan itu.

We finally obtained permission to repair the building. (neutral/formal lexical mendapatkan)

Peserta dapat memperoleh sertifikat setelah menyelesaikan seluruh modul.

Participants can obtain a certificate after completing all modules. (formal; modal dapat plus lexical memperoleh)

The last sentence contains dapat as a modal because it precedes the verb memperoleh. Compare peserta mendapat sertifikat, where mendapat itself selects the noun sertifikat.

Mampu: enough internal capacity

Mampu + predicate says that a person, organization, system, or material has the capacity needed to meet a challenge (neutral/formal). It is especially useful when resources are in doubt or noteworthy.

Physical or mental capacity

Setelah menjalani terapi, pasien itu mampu berjalan sejauh lima ratus meter.

After therapy, the patient is able to walk five hundred meters. (physical capacity)

Ia tetap mampu berkonsentrasi meskipun ruangannya cukup bising.

She remains able to concentrate even though the room is quite noisy. (mental capacity)

Atlet tersebut mampu mempertahankan kecepatannya sampai garis akhir.

The athlete is capable of maintaining her speed to the finish line. (physical performance)

Financial and institutional capacity

Keluarga itu belum mampu membayar biaya perawatan tambahan.

That family cannot yet afford the additional treatment costs. (financial capacity)

Perusahaan kecil tersebut mampu menyediakan dua ratus lapangan kerja tetap.

The small company is capable of providing two hundred permanent jobs. (institutional capacity)

Server baru mampu menangani sepuluh ribu permintaan per menit.

The new server can handle ten thousand requests per minute. (technical capacity)

Apakah anggaran desa mampu menanggung biaya perbaikan jembatan?

Can the village budget cover the cost of repairing the bridge? (financial capacity question)

Using bisa would simply say that the action is possible. Mampu directs attention to strength, expertise, processing power, personnel, or money that sustains the action.

💡

Use mampu when “enough capacity” is part of the message, not as a formal decoration added to every bisa sentence.

When two forms are possible

The same real-world situation can be framed from different angles.

Tari bisa menyelesaikan teka-teki itu.

Tari can solve that puzzle. (ordinary statement of ability)

Tari mampu menyelesaikan teka-teki itu dalam waktu dua menit.

Tari is capable of solving that puzzle in two minutes. (noteworthy demonstrated capacity)

Jalan ini bisa dilewati sepeda motor saat cuaca kering.

Motorcycles can use this road in dry weather. (practical feasibility)

Jalan ini dapat dilalui kendaraan ringan selama pekerjaan berlangsung.

This road may be used by light vehicles while work is under way. (formal public information)

Kendaraan itu mampu melewati tanjakan curam tanpa kehilangan tenaga.

That vehicle is capable of climbing a steep slope without losing power. (mechanical capacity)

The proposition overlaps, but the source differs: situation, official availability, or the vehicle’s engineering.

Negation reveals the contrast

Saya tidak bisa datang karena kereta terakhir sudah berangkat.

I cannot come because the last train has left. (circumstantial impossibility)

Dokumen ini tidak dapat diproses tanpa tanda tangan pemohon.

This document cannot be processed without the applicant’s signature. (formal procedural impossibility)

Tim kami tidak mampu menyelesaikan pekerjaan sebesar itu dalam dua hari.

Our team is not capable of completing work of that scale in two days. (insufficient capacity)

Adik saya belum bisa mengendarai sepeda tanpa roda bantu.

My younger sibling cannot ride a bicycle without training wheels yet. (ability expected later)

Usaha itu belum mampu menghasilkan keuntungan secara stabil.

That business is not yet able to generate a stable profit. (developing institutional capacity)

Belum bisa is the ordinary learning-development phrase; belum mampu treats adequate capacity as a threshold not yet reached.

Permission: use bisa deliberately

Neither dapat nor mampu is the general everyday replacement for boleh “be permitted.”

Boleh saya memotret di ruangan ini?

May I take photographs in this room? (direct permission question)

Bisa saya memotret tanpa lampu kilat?

Could I take a photograph without flash? (polite feasibility/permission question)

Dapatkah saya memperoleh salinan keputusan tersebut?

May/can I obtain a copy of that decision? (formal written or highly careful question)

Mampukah saya memotret di sini?

Am I capable of taking photographs here? (capacity reading; not the normal permission question)

Dapatkah is possible in formal questions, but it sounds administrative or written. Mampukah questions the speaker’s ability, not the institution’s authorization.

Common Mistakes

1. Treating all three as style-only synonyms

❌ Mampu, bisa, dan dapat selalu berbeda hanya dalam tingkat kesopanan.

Incorrect—the forms can select skill, feasibility, formal availability, acquisition, or underlying capacity.

✅ Pilihan modal mengikuti sumber kemungkinan yang sedang dibicarakan.

The modal choice follows the source of possibility under discussion.

2. Using mampu for an ordinary permission request

❌ Mampukah saya meninggalkan tas di meja informasi?

Wrong question for permission—it asks about the speaker’s capacity.

✅ Boleh saya menitipkan tas di meja informasi selama satu jam?

May I leave my bag at the information desk for an hour?

3. Missing lexical dapat

❌ Dalam ‘Saya dapat hadiah’, dapat selalu berarti ‘mampu’.

Incorrect interpretation—here dapat is a lexical verb meaning receive.

✅ Saya mendapat hadiah kecil dari teman-teman kantor.

I received a small gift from my coworkers.

4. Using bisa where capacity is the point

❌ Bisa selalu sama tepatnya dengan mampu ketika yang dinilai adalah kapasitas keuangan.

Incorrect claim—mampu specifically foregrounds the resources required to meet the cost.

✅ Laporan keuangan menilai apakah keluarga itu mampu membayar cicilan bulanan.

The financial report assesses whether that family can afford the monthly installments.

5. Treating formal dapat as an affix

❌ Informasi tersebut dapatdiakses tanpa kata sandi.

Incorrect spelling—modal dapat remains separate from the following passive verb.

✅ Informasi tersebut dapat diakses tanpa memasukkan kata sandi.

That information can be accessed without entering a password. (formal)

Key Takeaways

Bisa is the everyday default for skill, feasibility, and politely framed requests.
Modal dapat states possibility in formal or careful language; lexical dapat/mendapat means obtain or receive.
Mampu foregrounds enough physical, mental, technical, institutional, or financial capacity.
Boleh asks permission directly; bisa often asks whether the request is workable.
Negation distinguishes circumstantial impossibility, procedural impossibility, and insufficient capacity.
