RT kami mengadakan gotong royong besok pagi.

RT stands for Rukun Tetangga, which is a very local neighborhood administrative unit in Indonesia.

In this sentence, RT kami means something like our neighborhood association or our RT area. It does not mean a house or a street by itself; it refers to that small local community unit.

So RT kami mengadakan... means that the neighborhood organization/community is the one organizing the event.

This is a very common question, because English only has we, while Indonesian has two versions:

• kami = we, but not including the listener
• kita = we, including the listener

So RT kami means our RT from the speaker’s point of view, but it may or may not include the person being spoken to as part of that we. In practice, it often just means the RT that we belong to.

If the speaker wanted to clearly include the listener in we, kita might be used in other contexts, but RT kami is very natural here.

Mengadakan means to hold, to organize, or to conduct an event or activity.

In this sentence, it means the RT is holding/organizing a gotong royong.

Examples:

• sekolah mengadakan lomba = the school is holding a competition
• kantor mengadakan rapat = the office is holding a meeting

So RT kami mengadakan gotong royong is literally Our RT is holding a gotong royong.

Yes. It is historically related to ada (to exist / there is), but as a learner, it is best to treat mengadakan as its own vocabulary item meaning to organize/hold.

Even if you know ada, that does not mean you can easily guess mengadakan from it in every context. So it is helpful to memorize:

• ada = there is / to exist
• mengadakan = to hold / organize

Gotong royong is an important Indonesian cultural term. It refers to working together cooperatively for the common good, especially in a neighborhood or community.

In everyday use, it often means a community work activity, such as:

• cleaning the neighborhood
• fixing public areas
• clearing drains
• preparing for a local event

So in this sentence, gotong royong probably means something like a community clean-up or neighborhood work day, depending on context.

Indonesian does not use articles like English a, an, and the in the same way.

So:

• mengadakan gotong royong can mean hold a gotong royong
• depending on context, it could also be understood as hold the gotong royong

Usually, context tells you whether it is definite or indefinite. That is very normal in Indonesian.

Besok pagi means tomorrow morning.

In Indonesian, time expressions are often placed at the end of the sentence, so:

• RT kami mengadakan gotong royong besok pagi.

is perfectly natural.

You could also move it for emphasis:

• Besok pagi, RT kami mengadakan gotong royong.

Both are correct. The version with besok pagi at the end sounds very normal and neutral.

Because Indonesian often uses time expressions directly, without a preposition like English on, at, or in.

So:

• besok pagi = tomorrow morning
• hari ini = today
• minggu depan = next week

You do not need a word equivalent to on or at here.

The subject is RT kami.

So the structure is:

• RT kami = subject
• mengadakan = verb
• gotong royong = object/activity
• besok pagi = time expression

A natural breakdown is:

• RT kami — our neighborhood association
• mengadakan — is holding
• gotong royong — a community work activity
• besok pagi — tomorrow morning

In this sentence, RT kami means our RT / our neighborhood association as the subject.

It does not mean in our neighborhood.

If you wanted to say in our neighborhood, you would usually say:

• di RT kami

Compare:

• RT kami mengadakan gotong royong. = Our RT is organizing a gotong royong.
• Di RT kami ada gotong royong. = There is a gotong royong in our neighborhood.

So the version without di makes RT kami the doer of the action.

Yes, it sounds very natural.

It is a normal kind of sentence you might hear in community or neighborhood contexts in Indonesia. Native speakers commonly talk this way when referring to local events organized by the RT.

A slightly more casual version might be:

• Besok pagi RT kami ada gotong royong.

That literally uses ada instead of mengadakan, and in conversation it can sound very natural too. But your original sentence is clear and standard.

You can negate the verb with tidak:

• RT kami tidak mengadakan gotong royong besok pagi.
• Our RT is not holding a gotong royong tomorrow morning.

If you use the more conversational version with ada, then:

• Besok pagi RT kami tidak ada gotong royong.

Both are possible, but the exact wording depends on whether you are negating holding the event or saying there is no event.

A simple yes/no question can be made just by using question intonation in speech:

• RT kami mengadakan gotong royong besok pagi?

In writing, you add a question mark:

• RT kami mengadakan gotong royong besok pagi?

You could also ask more explicitly:

• Apakah RT kami mengadakan gotong royong besok pagi?

Both are correct. Apakah makes it more clearly a formal yes/no question.
