Learn Hardcore Indonesian: Lampiran rinci berisi bukti pembayaran. - The detailed attachment contains proof of payment.

Rinci lampiran is not grammatical as an attributive phrase. If you want a heavier/clearer modifier, you can say lampiran yang rinci. As a predicate, you can say Lampiran itu rinci (The attachment is detailed).

Why isn’t there yang here? When would I say lampiran yang rinci?

Yang introduces a descriptive clause or emphasizes the modifier. Use it when:

the modifier is long: lampiran yang sangat rinci dan lengkap
you need to specify/contrast: lampiran yang rinci, bukan yang ringkas

For a simple adjective, lampiran rinci is preferred and lighter.

Why use berisi instead of adalah?

berisi means “to contain/hold.” It describes contents.
- Lampiran rinci berisi bukti pembayaran. = The attachment contains proof of payment.
adalah equates two nouns.
- Lampiran rinci adalah bukti pembayaran. = The detailed attachment is the proof of payment (i.e., the attachment itself is the proof).

Choose based on whether you mean “contains” or “is.”

Can I replace berisi with memuat, mengandung, or berupa?

memuat ≈ “to include/carry/contain” (transitive); very common in documents.
- Lampiran rinci memuat bukti pembayaran.
mengandung = “to contain” (often for substances/abstract ideas); also means “to be pregnant,” so use carefully.
- Dokumen ini mengandung informasi sensitif.
berupa = “to be in the form of.”
- Lampiran rinci berupa bukti pembayaran. (the attachment is in the form of proof of payment)

All are acceptable depending on nuance; berisi/memuat are the safest here.

Is lampiran singular or plural here? How do I say “attachments”?

Indonesian nouns are number-neutral without a marker, so lampiran can be singular or plural from context. To mark plural explicitly, use:

reduplication: lampiran-lampiran
quantifiers: beberapa lampiran (several), dua lampiran (two)
determiners: semua lampiran (all attachments)

How do I say “this/the attachment” explicitly?

Use demonstratives or -nya:

Lampiran ini berisi... (this attachment)
Lampiran itu/tersebut berisi... (that/the aforementioned attachment)
Lampirannya berisi... (the/its attachment; -nya can mark definiteness or possession)

What’s the nuance difference between rinci, terperinci, and detail?

rinci: native adjective, common and neutral.
terperinci: slightly more formal/literary; “detailed, in detail.”
detail: loanword, widely used; acceptable but a bit more casual in some contexts.

As nouns:

rincian/perincian = details/breakdown (both used; perincian can feel a bit more “itemization”-like).

Can I say secara rinci instead of rinci here?

Use secara rinci to modify verbs (adverbial), not nouns:

Good: Hal itu dijelaskan secara rinci. (explained in detail)
For a noun, use the adjective: lampiran rinci or lampiran yang terperinci, not lampiran secara rinci.

What exactly does bukti pembayaran cover? How is it different from kuitansi/kwitansi, nota, faktur, and struk?

bukti pembayaran: any proof of payment (generic) — receipt, bank transfer slip, screenshot, etc.
kuitansi (standard; older spelling kwitansi): a formal receipt acknowledging payment.
nota: a note/bill; can be informal sales note; varies by context.
faktur: an invoice (often business/tax context; faktur pajak).
struk: a small cash register receipt from a store.

Is bukti pembayaran singular or plural? How do I say “multiple proofs of payment”?

It’s number-neutral. To make it plural, say:

bukti-bukti pembayaran
beberapa bukti pembayaran
beragam/berbagai bukti pembayaran

Are there alternative ways to phrase the same idea?

Yes:

Bukti pembayaran ada di lampiran rinci.
Bukti pembayaran tercantum dalam lampiran rinci.
Bukti pembayaran terdapat pada lampiran rinci.
Lampiran rinci memuat bukti pembayaran.

What register is this sentence? Is it natural in emails or official documents?

It’s neutral-to-formal and fits well in emails, reports, and official correspondence. For very formal tone, you might prefer tercantum dalam or terdapat pada; for everyday messages, berisi is perfectly natural.

Should I say berisi tentang ...?

Prefer not to. Berisi already implies contents, so berisi tentang is redundant. Use:

Surat itu berisi pengumuman tentang jadwal baru. (berisi + noun phrase)
Or drop berisi and use tentang/mengenai: Surat itu mengenai jadwal baru.

What are the word-building pieces in berisi and pembayaran?

ber- + isi → berisi: the prefix ber- often means “to have/be with,” so berisi = “to have contents; to contain.”
bayar (pay) → membayar (to pay; meN- prefix) → pembayaran (payment; peN- -an nominalization).

How do I negate this sentence?

Use tidak before the verb:

Lampiran rinci tidak berisi bukti pembayaran. If you mean the attachment is empty, you can also say:
Lampiran itu kosong. For “not yet,” use belum:
Lampiran rinci belum berisi bukti pembayaran.

Is berisikan acceptable?

You’ll see berisikan in formal/bureaucratic writing, and it’s understood, but berisi is simpler and always safe. For example:

Preferred: Formulir ini berisi data diri.
Also seen: Formulir ini berisikan data diri.
