Petugas di loket meminta dua lembar fotokopi, lalu memberi stempel pada formulir saya sambil menjelaskan bagian mana yang masih kosong.

Petugas means staff member, officer, or clerk, depending on context.

In Indonesian, it is very common to omit seorang when you are just referring to a person in a general way. So:

• Petugas di loket = the clerk at the counter / the staff member at the desk
• Seorang petugas di loket would also be possible, but it sounds a bit more explicit, like a staff member at the counter

In everyday narration, Indonesian often leaves out articles like a and the, since the language does not require them the way English does.

Di means at / in / on, depending on context, and loket means counter, service window, or ticket window.

So petugas di loket means:

• the clerk at the counter
• the officer at the service window

Here di loket tells you where the staff member is.

Lembar is a classifier for flat sheet-like things, such as paper.

So:

• dua lembar fotokopi = two sheets/copies of photocopies
• literally: two sheet photocopy

In Indonesian, classifiers are often used after numbers:

• dua orang = two people
• tiga buah buku = three books (less formal/common in some contexts)
• dua lembar kertas = two sheets of paper

You may hear dua fotokopi in casual speech, but dua lembar fotokopi is more precise and natural when talking about paper documents.

It can be used for both, depending on context.

In this sentence, dua lembar fotokopi clearly means two photocopies as documents.

But fotokopi can also refer to the act or result in other contexts, for example:

• Saya mau fotokopi KTP. = I want to photocopy my ID card.
• Tolong bawa fotokopinya. = Please bring the photocopy.

So the meaning depends on how it is used.

Meminta is the meN- form of minta.

Very roughly:

• minta = ask for / request
• meminta = to request / requested

In formal or standard written Indonesian, meminta is the expected form here because it is an active transitive verb with a subject:

• Petugas ... meminta dua lembar fotokopi
  = The clerk requested two photocopies.

In everyday speech, people often shorten verbs and say minta, but in a written sentence like this, meminta sounds more complete and standard.

Lalu means then, after that, or next.

It connects actions in sequence:

1. the clerk asked for two photocopies
2. lalu = then
3. the clerk stamped the form
4. while explaining which part was still empty

So lalu shows that the next action happened after the first one.

Both ideas are possible in Indonesian, but memberi stempel pada ... is a very natural way to say to put a stamp on ... or to stamp ...

Breaking it down:

• memberi = to give / to apply
• stempel = stamp
• pada formulir saya = on my form

So literally it is something like:

• gave a stamp to/on my form

This is a common Indonesian pattern:

• memberi tanda pada dokumen = put a mark on the document
• memberi nama pada anak itu = give that child a name

A verb like menstempel may also be heard, but memberi stempel pada ... is clear and idiomatic.

Pada here means on in the sense of onto / upon a document or surface.

So:

• memberi stempel pada formulir saya = put a stamp on my form

Without pada, the sentence would feel less complete with this verb pattern. Since the structure is memberi stempel pada X, pada introduces the thing receiving the stamp.

You can think of it as similar to:

• menulis pada kertas = write on paper
• memberi cap pada surat = stamp the letter

In Indonesian, possession usually comes after the noun.

So:

• formulir saya = my form
• rumah saya = my house
• nama saya = my name

This is the normal word order in Indonesian. English says my form, but Indonesian says something more like form my.

Sambil means while, at the same time as, or while doing something else.

In this sentence:

• memberi stempel pada formulir saya sambil menjelaskan ...
• = stamped my form while explaining ...

So the stamping and the explaining happened at the same time, or at least overlapped.

A useful pattern is:

• sambil + verb
• Ia makan sambil menonton TV. = He ate while watching TV.
• Dia berjalan sambil berbicara. = She walked while talking.

Bagian means part or section.

So:

• bagian mana = which part / which section

This is more natural and specific than just mana here, because the speaker is talking about parts of the form.

So the phrase means:

• explaining which section was still empty

If you said only mana yang masih kosong, it might still be understood, but bagian mana makes it much clearer that you are talking about sections of the form.

Here yang introduces a descriptive clause, similar to that / which is in English.

So:

• bagian mana yang masih kosong
• literally: which part that is still empty

Natural English:

• which part was still blank
• which section was still unfilled

This is a very common Indonesian structure:

• orang yang datang tadi = the person who came earlier
• buku yang saya baca = the book that I read
• bagian yang salah = the part that is wrong

So yang masih kosong describes bagian mana.

Kosong means empty, blank, or not filled in, depending on context.

Masih means still.

So:

• masih kosong = still empty / still blank / not filled in yet

In a form-related context, kosong usually means a field or section has not been filled out.

Examples:

• Formulir ini masih kosong. = This form is still blank.
• Bagian alamat masih kosong. = The address section is still blank.

The word masih adds the idea that up to that point, it had not yet been completed.

It is understood to be the same subject as the earlier verbs: petugas di loket.

So the sequence is:

• Petugas ... meminta ...
• (Petugas) lalu memberi stempel ...
• (Petugas) sambil menjelaskan ...

Indonesian often omits repeated subjects when they are obvious from context. So even though petugas is only stated once, it is understood as the subject of all those actions.

Indonesian does not have articles that work like English a and the.

So a noun like petugas, loket, formulir, or stempel can often mean:

• a clerk
• the clerk
• a form
• the form

The exact meaning comes from context.

In this sentence:

• Petugas di loket is naturally understood as the clerk at the counter
• formulir saya is clearly my form

So Indonesian relies much more on context than English does for this kind of information.

A more literal breakdown would be:

• Petugas di loket = the staff member at the counter
• meminta dua lembar fotokopi = requested two sheets of photocopy
• lalu memberi stempel pada formulir saya = then gave a stamp to/on my form
• sambil menjelaskan bagian mana yang masih kosong = while explaining which part was still empty

That literal version is helpful for understanding Indonesian structure, but natural English would smooth it out, for example:

• The clerk at the counter asked for two photocopies, then stamped my form while explaining which sections were still blank.

This is very common when learning Indonesian: the literal structure helps you see the grammar, but the best English translation usually sounds less word-for-word.
