Dia dipecat kemarin.

In Indonesian, dia can mean either he or she. The language usually does not mark gender in third-person singular pronouns.

So Dia dipecat kemarin could mean:

• He was fired yesterday
• She was fired yesterday

If the speaker wants to make gender clear, they usually do it through context or by adding a noun, such as:

• pria itu = that man
• wanita itu = that woman

Dipecat is a passive verb. It comes from the root pecat, which is related to dismissing or firing someone from a job or position.

The prefix di- often marks the passive voice in Indonesian:

• memecat = to fire someone
• dipecat = to be fired

So:

• Perusahaan itu memecat dia = The company fired him/her
• Dia dipecat = He/She was fired

Yes. Dia dipecat kemarin is a passive sentence.

It focuses on the person affected by the action, not on who did the action.

Compare:

• Bosnya memecat dia kemarin = His/Her boss fired him/her yesterday.
  
  • active
• Dia dipecat kemarin = He/She was fired yesterday.
  
  • passive

Indonesian uses passive very naturally, often more often than English does.

Indonesian does not need a separate word like was in this kind of sentence.

English often uses:

• was fired

Indonesian just uses the passive verb directly:

• dipecat

Past time is understood from kemarin = yesterday.

So the idea of past time comes from the time word, not from changing the verb form.

No. Kemarin means yesterday, and it can appear in different positions.

These are all natural:

• Dia dipecat kemarin
• Kemarin dia dipecat
• Dia kemarin dipecat

The version with kemarin at the end is very common and neutral. Putting kemarin at the beginning often gives a little more focus to the time.

Yes, but the most common meaning is to be fired, dismissed, or removed from a position.

It is often used for:

• jobs
• official positions
• membership or roles

Depending on context, it can sometimes feel like:

• dismissed
• sacked
• removed from office

For example:

• Dia dipecat dari pekerjaannya = He/She was fired from his/her job
• Dia dipecat dari jabatannya = He/She was removed from his/her position

Because dipecat is passive, not active.

If the subject were the one doing the firing, Indonesian would normally use memecat:

• Dia memecat karyawannya kemarin = He/She fired his/her employee yesterday

But in your sentence:

• Dia dipecat kemarin

the subject dia receives the action. So dia is the person who got fired.

This is a very important difference:

• dipecat = was fired, was dismissed
  
  • the person did not choose to leave
• berhenti = quit, resigned, stopped working
  
  • the person did choose to leave, or at least the sentence presents it that way

Compare:

• Dia dipecat kemarin = He/She was fired yesterday
• Dia berhenti kemarin = He/She quit yesterday

So dipecat is involuntary, while berhenti is usually voluntary.

Because here di- is a prefix, not a separate word.

In Indonesian:

• passive prefix di- is written attached to the verb
  
  • dipecat
  • dibuka
  • ditulis

But the preposition di meaning in / at / on is written separately:

• di rumah = at home
• di kantor = at the office

So:

• dipecat = correct
• di pecat = incorrect

Yes, it is completely natural and idiomatic.

It sounds like normal spoken and written Indonesian. It is short, clear, and very common in the kind of context where the speaker either does not know, does not care, or does not want to mention who fired the person.

If you want to add more detail, you could say:

• Dia dipecat dari pekerjaannya kemarin = He/She was fired from his/her job yesterday
• Dia dipecat oleh bosnya kemarin = He/She was fired by his/her boss yesterday

But the shorter sentence by itself is perfectly normal.

Both dia and ia can mean he or she, but they are used a bit differently.

• dia is very common in speech and everyday writing
• ia is more formal and is mostly used in writing

Also, ia cannot be used in every position where dia can. For most learners, using dia is the safer and more natural choice in conversation.

So in everyday Indonesian:

• Dia dipecat kemarin sounds very normal

Using Ia dipecat kemarin is also possible, but it sounds more formal or literary.
