Kulit buah dan sisa sayur masuk ke wadah organik, sedangkan botol plastik masuk ke wadah anorganik.

Yes. Kulit means skin or peel, and buah means fruit. So kulit buah literally means fruit skin/peel.

In natural English, we would usually say fruit peels or fruit peel depending on context. In Indonesian, kulit buah is a normal and natural way to refer to that category in general.

Sisa means leftover, remaining part, or scrap.
Sayur means vegetable or sometimes vegetable dish, depending on context.

So sisa sayur here means vegetable scraps or leftover vegetables. In a waste-sorting sentence like this, it most naturally refers to bits of vegetables being thrown away.

Indonesian often does not mark plural when the meaning is already clear from context.

So:

• kulit buah can mean fruit peel or fruit peels
• sisa sayur can mean vegetable scrap or vegetable scraps
• botol plastik can mean plastic bottle or plastic bottles

Plural is only marked when needed, often by reduplication:

• botol-botol plastik = plastic bottles
• buah-buahan = fruits

But in this sentence, plural marking is unnecessary because it is talking about categories of waste in general.

Dan simply means and. It joins kulit buah and sisa sayur into one combined subject/topic:

• Kulit buah dan sisa sayur = fruit peels and vegetable scraps

Yes, masuk basically means enter or go in. But in Indonesian, it is also commonly used for things being placed into a container or category.

So:

• masuk ke wadah organik = go into the organic container
• masuk ke wadah anorganik = go into the inorganic container

This sounds natural in Indonesian. English might prefer go in, belong in, or should be put in, but Indonesian often just uses masuk.

Because ke is the preposition meaning to or into. It marks direction or destination.

• masuk ke wadah organik = go into the organic container

Without ke, the phrase would sound incomplete or unnatural in standard Indonesian in this context.

Wadah means container, holder, or receptacle. It is a fairly general word.

Tempat sampah specifically means trash can, bin, or garbage container.

So in this sentence:

• wadah organik = organic container/bin
• wadah anorganik = inorganic container/bin

Using wadah is fine because the sentence is talking about sorting items into categories of containers. In everyday speech, people might also say tempat sampah organik and tempat sampah anorganik.

Sedangkan is a contrast word. It often means:

• while
• whereas
• on the other hand

It connects two parts of the sentence and shows a contrast between them:

• organic waste goes in one container,
• plastic bottles go in another.

So sedangkan is stronger than dan.
If you used dan, it would just mean and, without highlighting the contrast.

Yes, absolutely. That is very common.

Structure here:

• Kulit buah dan sisa sayur masuk ke wadah organik, sedangkan botol plastik masuk ke wadah anorganik.

This is a very natural way to say:

• Fruit peels and vegetable scraps go into the organic container, while plastic bottles go into the inorganic container.

Because in Indonesian, the head noun usually comes first, and the describing noun comes after it.

So:

• botol plastik = plastic bottle
• literally: bottle plastic

This is a very common pattern:

• rumah sakit = hospital
• jus buah = fruit juice
• sampah plastik = plastic waste

English often puts the describing word before the noun, but Indonesian often puts it after.

In this context:

• organik = biodegradable waste, like food scraps, fruit peels, leaves, etc.
• anorganik = non-biodegradable waste, like plastic, glass, metal, and so on

So wadah organik and wadah anorganik are labels for different waste categories.

These words are borrowed from international vocabulary, so they may look familiar to English speakers.

It reads as a general rule or instruction about waste sorting.

Because Indonesian verbs do not change form for tense, masuk by itself does not tell you whether something is present, past, or future. Context does that.

In this case, the sentence sounds like:

• a rule,
• a guideline,
• or a general statement.

English may translate it with go into, should go into, or are put into, depending on context.

Good question. Indonesian could also use a passive or causative-style form, for example:

• Kulit buah dan sisa sayur dimasukkan ke wadah organik...

That would mean Fruit peels and vegetable scraps are put into the organic container...

But the original sentence uses masuk, which is simpler and more direct. It focuses on where the items belong, not explicitly on the person putting them there.

So:

• masuk = go in / belong in
• dimasukkan = are put in

Both can work, but masuk is very natural for instructions like sorting waste.

No. Indonesian verbs do not change depending on the subject.

So masuk stays masuk whether the subject is singular or plural:

• botol plastik masuk ke wadah anorganik
• botol-botol plastik masuk ke wadah anorganik

The verb does not change.

This is very different from English, where we distinguish between goes and go.

By itself, sayur can sometimes refer to:

• vegetables in general, or
• a vegetable dish

But in this sentence, because it appears in sisa sayur and the topic is waste sorting, the most natural interpretation is vegetable scraps/leftover vegetables rather than a specific cooked dish.

So yes, the word can be broader in other contexts, but here the meaning is clear from context.

It is not always absolutely required in casual writing, but it is very helpful and standard here because sedangkan connects two contrasting clauses.

The comma makes the structure easier to read:

• first clause: Kulit buah dan sisa sayur masuk ke wadah organik
• second clause: sedangkan botol plastik masuk ke wadah anorganik

So the punctuation is natural and appropriate.
