Ketua RT mengumumkan bahwa iuran bulan ini dipakai untuk memperbaiki lampu jalan di gang depan.

Ketua RT means the head/chairperson of the RT, a very local neighborhood administrative unit in Indonesia.

• ketua = leader, chairperson, head
• RT = Rukun Tetangga

There is no perfect one-word English equivalent, but you can think of it as something like the neighborhood block head or local neighborhood chief.

Indonesian does not usually use articles like a, an, or the.

So:

• Ketua RT can mean the RT head
• iuran bulan ini can mean this month’s dues/the dues for this month
• lampu jalan can mean the streetlight(s) depending on context

Whether something is definite or indefinite is usually understood from context rather than marked with a separate word.

bahwa means that and introduces a reported statement or clause.

So:

• mengumumkan bahwa ... = announced that ...

In English, that is often optional, and in Indonesian, bahwa can also sometimes be omitted in casual speech. But in more formal or clear written Indonesian, it is common and natural.

Iuran means a contribution, fee, or dues collected from members of a group or community.

In this sentence, it most likely refers to a regular neighborhood payment collected from residents. Depending on context, it could be translated as:

• dues
• contribution
• community fee
• collection

It is not just any money; it usually suggests money that people are expected to contribute regularly or jointly.

In Indonesian, modifiers usually come after the noun.

So:

• iuran bulan ini = this month’s dues / the dues for this month

Breakdown:

• iuran = dues/contribution
• bulan ini = this month

Literally, it is closer to dues this month, but natural English is this month’s dues.

Dipakai is a passive form, while memakai/menggunakan are active forms.

• dipakai = is used / are used
• memakai = use / uses
• menggunakan = use / uses

Here the focus is on the money (iuran bulan ini), not on who is using it. That is why passive is natural:

• iuran bulan ini dipakai ... = this month’s dues are used ...

If you used an active verb, you would normally need an explicit subject, for example:

• Warga memakai iuran bulan ini untuk ...
• Pengurus menggunakan iuran bulan ini untuk ...

No. They are completely different things.

1. di- in dipakai is a prefix that marks a passive verb.

   • pakai = use
   • dipakai = be used

2. di in di gang depan is a preposition meaning in / at / on.

A very important spelling rule:

• passive prefix: written together → dipakai
• preposition: written separately → di gang

So spelling helps you tell them apart.

Untuk means for or to, and memperbaiki means to repair / to fix.

So:

• dipakai untuk memperbaiki = used to repair

About memperbaiki:

• base idea: baik = good
• memperbaiki = to make good again, to repair, to fix

It is a transitive verb, so it takes an object:

• memperbaiki lampu jalan = repair the streetlight(s)

You could also see related forms like:

• perbaikan = repair(s), repair work
• memperbaiki = to repair

Lampu jalan is a fixed noun phrase meaning streetlight or road light.

• lampu jalan = a type of lamp: a streetlight
• lampu di jalan = a lamp that is on the road/in the street

So lampu jalan is more like a compound noun, not just a lamp located somewhere.

No. In Indonesian, gang often means a small alley, lane, or narrow passageway.

So:

• di gang depan = in the alley out front / in the front alley

This is a very common word in Indonesian addresses and everyday speech, and it usually has nothing to do with a criminal gang.

Here, depan describes the location of the gang.

So gang depan means something like:

• the front alley
• the alley in front
• the alley out front

In natural English, the best translation depends on context. It could refer to:

• the alley in front of the speaker’s house
• the alley at the front of the neighborhood area
• the alley ahead of where people are speaking from

Yes. This is very common in Indonesian.

In the sentence:

• iuran bulan ini dipakai untuk memperbaiki ...

the sentence does not say explicitly who is using the money. That is normal, especially when:

• the agent is obvious from context
• the speaker wants to focus on the thing affected
• the exact agent is not important

If needed, Indonesian can add the agent:

• iuran bulan ini dipakai oleh warga untuk ...
• iuran bulan ini dipakai oleh pengurus untuk ...

But leaving it out is very natural.

The structure is:

• Ketua RT = subject
• mengumumkan = verb
• bahwa ... = content clause (that ...)

Inside the bahwa clause:

• iuran bulan ini = subject/topic of the passive clause
• dipakai = passive verb
• untuk memperbaiki lampu jalan di gang depan = purpose phrase

So the overall pattern is:

[Subject] + [announced] + [that-clause]

And inside the that-clause:

[thing affected] + [passive verb] + [purpose] + [location]
