Satpam perempuan di komplek kami ramah, tetapi dia tetap tegas saat ada tamu yang parkir sembarangan di gang kecil.

Yes. Satpam is a very common everyday Indonesian word meaning security guard.

It comes from satuan pengamanan, but in daily speech people usually just say satpam. It is completely normal and natural in conversation.

For example:

• satpam sekolah = school security guard
• satpam kantor = office security guard

In Indonesian, the main noun usually comes first, and words that describe or specify it come after it.

So:

• satpam perempuan = female security guard
• guru laki-laki = male teacher
• dokter perempuan = female doctor

The head word here is satpam, and perempuan tells you what kind of satpam.

If you said perempuan satpam, it would sound much less natural in this context.

Both can mean woman/female, but they are used a little differently.

• perempuan is a very common, neutral word
• wanita can sound a bit more formal, polite, or official

So satpam perempuan and satpam wanita can both be understood, but perempuan feels very natural in everyday speech.

Komplek means a housing complex, residential complex, or sometimes a neighborhood development.

The more formal spelling is kompleks, but komplek is very common in everyday Indonesian speech and writing.

So:

• di komplek kami = in our housing complex / in our residential area

You may also hear perumahan in similar contexts, depending on the place.

This is an important Indonesian distinction.

• kami = we/us/our, but not including the listener
• kita = we/us/our, including the listener

So komplek kami means our complex, but the speaker is not necessarily including the person they are talking to.

If the speaker and listener both live there, komplek kita might be more appropriate.

Indonesian often does not use a verb like is/are in simple statements.

So:

• Satpam perempuan di komplek kami ramah literally looks like female security guard in our complex friendly
• but it naturally means The female security guard in our complex is friendly

This is completely normal in Indonesian.

Other examples:

• Dia tinggi = He/She is tall
• Rumah itu besar = That house is big

Both mean but.

• tetapi is a bit more formal or careful
• tapi is more casual and very common in speech

In this sentence, tetapi fits well because the sentence is a little more polished in style. In everyday conversation, many people would simply say tapi.

Dia can mean he or she. Indonesian third-person pronouns do not usually show gender.

We understand she here because the sentence already says satpam perempuan, so the person is clearly female.

A related point:

• dia is very common in speech and writing
• ia also means he/she, but sounds a bit more formal and is used more in writing

Tetap means still, remain, or continue to be.
Tegas means firm, strict, or assertive.

So dia tetap tegas means she is friendly, but she still remains firm when necessary.

That gives the sentence a nice contrast:

• ramah = friendly
• tetap tegas = still firm

It suggests she is kind, but not weak or permissive.

Here, saat means when, and ada means there is/there are or when there exist.

So:

• saat ada tamu = when there is a guest / when guests are around / when visitors come

In natural English, we usually would not translate ada word-for-word every time. It is just helping introduce the situation: visitors are present.

This is very common in Indonesian:

• kalau ada masalah = if there is a problem
• saat ada rapat = when there is a meeting

Yang introduces a clause that describes a noun, similar to who, that, or which in English.

So:

• tamu yang parkir sembarangan = guest(s) who park carelessly / visitors who park improperly

Here:

• tamu = guest/visitor
• yang parkir sembarangan = who park carelessly / who park wherever they like

This whole part describes which guests we mean.

Compare:

• orang yang bekerja di sini = the person who works here
• mobil yang merah = the car that is red

Yes. In everyday Indonesian, parkir can function as a verb meaning to park.

So:

• parkir sembarangan = park carelessly / park improperly

In more formal Indonesian, you may also see:

• memarkir = to park something
• memarkir mobil = to park a car

But in casual and very natural usage, parkir by itself is extremely common.

Sembarangan often means carelessly, improperly, randomly, or without regard for rules.

In parkir sembarangan, it means the guests are parking in a way they should not—probably blocking space, ignoring rules, or parking wherever they like.

So it is not just random in a neutral sense; it often has a negative sense of thoughtless or inconsiderate behavior.

No. Indonesian gang does not mean a group of criminals here.

In Indonesian, gang means a small alley, lane, or narrow street.

So:

• di gang kecil = in a small alley / on a narrow little lane

Also notice the word order:

• gang kecil = alley + small

That is normal Indonesian noun-adjective order.

Because Indonesian often does not mark singular and plural as explicitly as English does.

Tamu can mean:

• a guest
• guests
• visitor
• visitors

The context tells you which one makes more sense. In this sentence, English might naturally translate it as guests or a guest, depending on the situation.

If Indonesian wants to be more explicit, it can say:

• seorang tamu = one guest
• para tamu = the guests
• tamu-tamu = guests

But very often, just tamu is enough.
