Dia bekerja di departemen itu.

In Indonesian, dia is a gender-neutral third-person singular pronoun. It can mean he or she, and the sentence itself usually does not tell you which one unless the wider context makes it clear.

A few useful notes:

• dia = he / she
• ia = a more formal/literary version of dia
• beliau = a respectful form for an important or older person

So a native English speaker often has to get used to the fact that Indonesian usually does not force you to mark gender here.

Bekerja is the standard verb meaning to work.

It comes from the root kerja (work) plus the prefix ber-, which often forms intransitive verbs.

• kerja = work, labor; also used informally as a verb in casual speech
• bekerja = to work, to be working

So:

• Dia bekerja di departemen itu. = standard, neutral
• Dia kerja di departemen itu. = common in conversation, but more informal

For learners, it is safest to use bekerja in normal written and spoken Indonesian unless you specifically want a casual tone.

Because here di is a preposition, meaning in, at, or sometimes on, depending on context.

• di departemen itu = in/at that department

When di is a preposition, it is written separately from the following word.

Compare that with di- as a prefix for passive verbs, which is written attached:

• di kantor = at the office
• ditulis = written
• dibuka = opened

This is one of the most important spelling distinctions in Indonesian.

In Indonesian, demonstratives like ini (this) and itu (that) usually come after the noun.

So:

• departemen itu = that department
• rumah itu = that house
• buku ini = this book

This is the normal Indonesian pattern, even though in English the demonstrative comes first.

It can often function like either one, depending on context.

Literally, itu means that, so departemen itu is literally that department. But in real usage, Indonesian often uses itu where English might naturally say the when referring to something already known or identifiable.

So in context, departemen itu could feel like:

• that department
• or the department

This is a common adjustment for English speakers, because Indonesian does not have articles exactly like a/an/the.

Not necessarily. Indonesian verbs usually do not change form for tense.

So Dia bekerja di departemen itu can mean different time references depending on context, for example:

• He/She works in that department.
• He/She is working in that department.

If you want to make time clearer, Indonesian often adds time words such as:

• sekarang = now
• dulu = in the past / back then
• besok = tomorrow
• sudah = already
• sedang = currently / in the process of
• akan = will

For example:

• Dia sedang bekerja di departemen itu. = He/She is working in that department.
• Dia sudah bekerja di departemen itu selama dua tahun. = He/She has worked in that department for two years.

Either can be natural, depending on how English expresses the idea.

In Indonesian, di is a general location marker. English often makes a choice that Indonesian does not need to make so precisely.

So:

• di departemen itu could be understood as in that department
• or at that department, though in that department is often the more natural English choice

Indonesian simply uses di for location and lets context do the rest.

Sometimes, yes, if the context already makes the subject clear.

For example, in conversation:

• Bekerja di departemen itu.
  This can be understood as He/She works in that department if everyone already knows who is being discussed.

However, Indonesian usually includes the subject when introducing new information or when clarity matters. So for learners, Dia bekerja di departemen itu is a very good full sentence.

No, it is a loanword, ultimately from a European source, and it is fully accepted in Indonesian.

It is commonly used in formal and organizational contexts, such as:

• departemen keuangan = finance department
• departemen pemasaran = marketing department

Depending on context, Indonesian may also use other words such as:

• bagian = section/division
• jurusan = department/major in an academic context

So departemen is completely normal, especially for workplace or administrative settings.

A simple learner-friendly pronunciation is:

• bekerja ≈ buh-KER-jah

A few helpful notes:

• the e in be- is often a schwa-like sound, similar to the a in English about
• ker has the main stress
• j in Indonesian sounds like English j in job
• a is usually pronounced clearly, like ah

Indonesian stress is often not as strong as in English, but saying buh-KER-jah will sound much closer than trying to pronounce every vowel like English spelling.

No. Adalah should not be used before a normal verb like bekerja.

Indonesian often uses adalah to link a subject with a noun phrase or description in more formal styles, but not with an action verb in this way.

So:

• Dia bekerja di departemen itu. = correct
• Dia adalah pegawai di departemen itu. = correct, because pegawai is a noun
• Dia adalah bekerja di departemen itu. = incorrect

This is a common mistake for English speakers who expect a form of to be before many predicates. Indonesian does not work that way.
