Mantel hitam Ibu digantung di dekat pintu.

In Indonesian, adjectives usually come after the noun they describe.

So:

• mantel hitam = black coat
• literally: coat black

This is the normal word order in Indonesian. English usually puts adjectives before the noun, but Indonesian usually puts them after.

Ibu can mean different things depending on context, including:

• mother / mom
• Mrs.
• a respectful way to address or refer to an adult woman

In this sentence, Ibu most naturally means something like Mother or Mrs., depending on the context already given.

Because it is capitalized, it may be being used like a title or name-like form, similar to Mother rather than just a mother.

This is how possession is commonly expressed in Indonesian.

The possessed thing comes first, and the possessor comes after:

• mantel hitam Ibu = Mother’s black coat / Mrs. X’s black coat

So the pattern is:

• noun + possessor

Examples:

• buku saya = my book
• rumah John = John’s house
• mantel hitam Ibu = Ibu’s black coat

Unlike English, Indonesian does not use 's.

In normal usage, it is understood as:

• [mantel hitam] Ibu = Ibu’s black coat

That is, hitam describes mantel, not Ibu.

So the structure is:

• mantel hitam = black coat
• mantel hitam Ibu = Ibu’s black coat

Indonesian often relies on normal grouping and context, and this phrase would normally not be interpreted as describing Ibu as black.

Digantung is a passive verb form.

It comes from:

• root: gantung = hang
• passive prefix: di-
• digantung = is hung / was hung / is being hung, depending on context

Indonesian does not mark tense the way English does, so digantung does not by itself tell you whether it is present or past. The time is usually understood from context or from time words if they are added.

These are two different di forms:

1. di- as a prefix on a verb

   • digantung
   • this marks the passive
   • it is written attached to the verb

2. di as a preposition meaning in, at, on

   • di dekat pintu
   • this is written separately

So:

• digantung = passive verb
• di dekat pintu = at/near the door

This is a very important spelling distinction in Indonesian.

Di dekat pintu means near the door.

Breakdown:

• di = at / in
• dekat = near
• pintu = door

So the phrase is a location phrase telling you where the coat is hung.

You can think of di dekat as at a place near something.

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

So a noun like mantel can mean:

• a coat
• the coat

The exact meaning depends on context.

In this sentence, English would naturally use the or a possessive phrase like Mother’s black coat, but Indonesian does not need a separate word for that.

The sentence focuses on the coat, not on the person who hung it.

• Mantel hitam Ibu digantung di dekat pintu. = the focus is on the coat

An active version would be something like:

• Seseorang menggantung mantel hitam Ibu di dekat pintu.
• Someone hung Mother’s black coat near the door.

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

Yes. Indonesian verbs usually do not change form for tense.

So digantung can mean:

• is hung
• was hung
• has been hung
• sometimes is being hung

Which one is correct depends on context.

If you want to make the time clearer, Indonesian can add time words such as:

• kemarin = yesterday
• tadi = earlier
• sekarang = now

Sometimes, yes, but the nuance changes.

• digantung emphasizes a passive action: something was hung / is hung
• tergantung often emphasizes the resulting state: something is hanging

So:

• Mantel hitam Ibu digantung di dekat pintu
  focuses more on the coat being hung there
• Mantel hitam Ibu tergantung di dekat pintu
  focuses more on the coat being in a hanging position there

In many contexts, both are possible, but they are not always exactly interchangeable.

You can add the agent with oleh = by.

For example:

• Mantel hitam Ibu digantung oleh pembantu di dekat pintu.
• Mother’s black coat was hung by the maid near the door.

In everyday Indonesian, the agent is often omitted if it is unknown, obvious, or unimportant.

The sentence is:

• Mantel hitam Ibu = noun phrase, the thing being talked about
• digantung = passive verb
• di dekat pintu = location phrase

So the overall structure is:

• subject/topic + passive verb + place

That makes the sentence feel very natural in Indonesian.
