Ibu mengikat tali sepatu adik saya sebelum dia berangkat ke sekolah.

Ibu literally means mother, but it is also widely used as a respectful form of address for an adult woman, somewhat like Mrs. or ma’am.

In this sentence, Ibu most naturally means Mother/Mom, because the rest of the sentence talks about adik saya (my younger sibling), so it sounds like a family context.

The capitalization can reflect that it is being used almost like a name or title, similar to Mom tied... in English.

Ikat is the basic root meaning to tie.

Mengikat is the active verb form made with the meN- prefix. In many Indonesian sentences, this is the normal way to express that someone actively does something to an object.

So:

• ikat = the root tie
• mengikat = to tie / tied as an active verb

In this sentence, Ibu mengikat tali sepatu... means Mother tied/is tying the shoelaces...

Tali sepatu literally breaks down as:

• tali = string, cord, lace
• sepatu = shoe

Together, tali sepatu means shoelace or shoelaces.

Indonesian often combines nouns this way without a special linking word. So instead of something like lace of shoe, it simply says shoe lace.

In Indonesian, possession usually works as:

noun + possessor

So:

• adik saya = my younger sibling
• buku saya = my book
• rumah saya = my house

This is different from English word order, where the possessor usually comes first: my younger sibling.

So adik saya is the normal pattern.

Adik does not tell you the gender.

It simply means younger sibling or sometimes younger person in a family/social relationship.

So adik saya can mean:

• my younger brother
• my younger sister
• more neutrally, my younger sibling

You need context if you want to know gender.

Grammatically, dia could refer to either:

• Ibu
• adik saya

So the sentence is technically ambiguous.

However, in normal real-world context, most people would understand dia as adik saya, because the person who is going to school is much more likely to be the younger sibling than the mother.

If you want to remove the ambiguity, Indonesian often just repeats the noun:

• Ibu mengikat tali sepatu adik saya sebelum adik saya berangkat ke sekolah.

That is clearer, even though it sounds more repetitive than English.

Indonesian often uses a full clause where English might use a shorter -ing form.

So English can say:

• before leaving for school

But Indonesian naturally says:

• sebelum dia berangkat ke sekolah
• literally: before he/she departs to school

This is very normal. Indonesian does not rely on -ing structures in the same way English does.

Berangkat means to leave, to depart, or to set off.

The ber- prefix often forms intransitive verbs, meaning verbs that do not take a direct object.

So:

• berangkat = to depart / to leave

You do not normally say berangkat with a direct object. Instead, you add a destination:

• berangkat ke sekolah = leave for school / go to school
• berangkat ke kantor = leave for the office

Ke is a preposition meaning to or toward a place.

So:

• ke sekolah = to school
• ke rumah = to home/the house
• ke pasar = to the market

Because berangkat involves movement toward a destination, ke is the natural preposition.

Indonesian does not have articles like a/an or the.

It also does not normally have to mark plural the way English does.

So tali sepatu can mean:

• a shoelace
• the shoelace
• shoelaces
• the shoelaces

The exact meaning depends on context.

In this sentence, English would probably say the shoelaces, but Indonesian does not need a separate word for that.

Yes. The sentence follows a very common pattern:

Subject + verb + object + time clause

Breaking it down:

• Ibu = subject
• mengikat = verb
• tali sepatu adik saya = object phrase
• sebelum dia berangkat ke sekolah = time clause

So the structure is very natural and standard for Indonesian prose and speech.

It could say ibu saya, but it does not have to.

Compare:

• Ibu mengikat... = Mother/Mom tied...
• Ibu saya mengikat... = My mother tied...

Using just Ibu sounds more direct and personal, like using Mom in English.

Using ibu saya sounds a little more explicit, like my mother. Both are possible; the choice depends on style and context.
