Saya menyimpan yogurt di freezer sebentar supaya lebih dingin, padahal adik saya suka memakannya langsung.

Menyimpan means to store, keep, or put something somewhere for a period of time. In this sentence, the speaker is not just placing the yogurt somewhere randomly—they are keeping it in the freezer briefly.

By contrast, menaruh or meletakkan usually focus more on the act of putting/placing something somewhere.

So:

• menyimpan yogurt di freezer = store/keep the yogurt in the freezer
• menaruh yogurt di freezer = put the yogurt in the freezer

Both can work, but menyimpan fits the idea a little better here because the yogurt stays there for a short while.

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

• di freezer = in the freezer

In Indonesian, di is written separately when it marks a location.

Compare:

• di freezer = in the freezer
• dimakan = eaten

In dimakan, di- is a passive verb prefix, so it is written attached to the verb.

A very common learner issue is confusing:

• di rumah = at home
• dibeli = bought

So in this sentence, di freezer is correct because it tells you where the yogurt is.

Sebentar means for a short time, briefly, or for a moment.

So:

• menyimpan yogurt di freezer sebentar = keep the yogurt in the freezer for a little while

It tells us the yogurt is not being stored there long-term—just long enough to get colder.

You could also hear:

• sebentar saja = just for a moment / only briefly

Supaya means so that or in order that. It introduces a purpose.

In this sentence:

• supaya lebih dingin = so that it becomes colder / so it will be colder

Yes, supaya and agar are very similar, and in many cases they are interchangeable.

• supaya lebih dingin
• agar lebih dingin

Both are natural.
Supaya often feels a bit more common in everyday speech, while agar can sound slightly more formal or neutral.

Lebih dingin means colder or cooler.

The word lebih makes a comparison:

• dingin = cold
• lebih dingin = colder / cooler

That makes sense here because yogurt is already cold, and putting it in the freezer makes it colder than before.

So the idea is not just to make it cold, but to make it even colder.

Padahal is a very useful word for showing contrast, often when the second part goes against what you might expect.

Depending on context, it can mean things like:

• whereas
• even though
• but actually
• when in fact

Here:

• Saya menyimpan yogurt di freezer sebentar supaya lebih dingin, padahal adik saya suka memakannya langsung.

This means the speaker chills the yogurt more, whereas / even though their younger sibling prefers eating it right away.

So padahal signals a contrast between:

1. what the speaker does, and
2. what the younger sibling prefers

Adik means younger sibling. It does not tell you gender by itself.

So adik saya can mean:

• my younger brother
• my younger sister

If you want to specify gender, you can add:

• adik laki-laki saya = my younger brother
• adik perempuan saya = my younger sister

This is a common point for English speakers, because English usually forces you to choose brother or sister, but Indonesian often does not.

Memakannya breaks down like this:

• makan = eat
• memakan = to eat, consume
• -nya = it / the specific thing being referred to

So memakannya means to eat it.

In this sentence, -nya refers back to yogurt.

So:

• adik saya suka memakannya langsung = my younger sibling likes to eat it right away

A few useful notes:

1. -nya often works like it, him/her, or the ... depending on context.
2. Indonesian often uses -nya to refer back to something already mentioned instead of repeating the noun.
3. In casual speech, people might also say something simpler like suka makan yogurtnya langsung or just suka makan langsung, depending on context.

Langsung literally often means directly or immediately, but in this sentence it is best understood as:

• right away
• straight away
• as is, without waiting

So:

• suka memakannya langsung = likes eating it right away

Here the meaning is that the younger sibling likes eating the yogurt without first putting it in the freezer longer.

The two saya words are doing different jobs:

1. Saya at the beginning is the subject: I
2. adik saya means my younger sibling

So the second saya is not a repeated subject—it is a possessor inside the phrase adik saya.

Indonesian often repeats nouns or pronouns more than English does when it helps keep things clear. In this sentence, adik saya clearly identifies whose younger sibling the speaker is talking about.

If you removed the second saya, adik would just mean younger sibling in a more general or context-dependent way.
