Questions & Answers about Petugas keamanan menutup pintu setelah pemeriksaan.

What does petugas keamanan mean, and is it singular or plural?

petugas means “officer” or “staff on duty,” and keamanan means “security.” Together, petugas keamanan = “security officer” or “security personnel.” In Indonesian, petugas can refer to one person or a group depending on context; you don’t change the form to mark plural.

How is the verb menutup formed, and what does the prefix me- do?

The root verb is tutup (“close”). By adding the active verb prefix me-, you get menutup = “to close.” The prefix triggers a sound change (t → n after me-), so me- + tutup → menutup.

How do I know that pintu is the object of menutup when there’s no marker?

Indonesian normally uses SVO (Subject-Verb-Object) word order:
Subject = Petugas keamanan
Verb = menutup
Object = pintu
Because pintu comes right after the verb, it functions as the direct object. No extra particle or preposition is needed.

What does setelah pemeriksaan literally mean, and why is pemeriksaan a noun?

setelah means “after,” and pemeriksaan is a noun meaning “inspection.” So setelah pemeriksaan = “after the inspection.” pemeriksaan is formed by the nominalizing circumfix pe-…-an on the verb root periksa (“to inspect”), turning it into a noun.

Can I move setelah pemeriksaan to the front? For example, Setelah pemeriksaan, petugas keamanan menutup pintu?

Yes. Indonesian allows you to place time or condition phrases at the beginning for emphasis or flow. It means exactly the same: “After the inspection, the security officer closed the door.”

How would I express this sentence in the passive voice?

You make pintu the subject and use the passive prefix di- on the verb:
Pintu ditutup petugas keamanan setelah pemeriksaan.
= “The door was closed by the security officer after the inspection.”

Are there common synonyms for petugas keamanan?

Yes. A very common informal term is satpam, short for satuan pengamanan (security unit/guard). You could say:
Satpam menutup pintu setelah pemeriksaan.
