Etalase yang satu berisi barang murah, sedangkan etalase yang lain berisi stok baru.

This is a very common Indonesian pattern for contrasting two things:

• yang satu = the one / one of them
• yang lain = the other one / the other

So:

• Etalase yang satu = one display case
• etalase yang lain = the other display case

It is a natural way to distinguish two items without needing separate labels like first and second.

Here, yang helps turn satu and lain into expressions meaning the one and the other.

You can think of it as pointing to a specific item out of a set:

• yang satu = the one
• yang lain = the other

This is not exactly the same as English that/which/who, even though yang often gets translated that way in other contexts.

Berisi means to contain, to be filled with, or to have contents of.

So:

• etalase yang satu berisi barang murah = one display case contains cheap goods
• etalase yang lain berisi stok baru = the other display case contains new stock

It sounds a bit more specific than just ada (there is/are), because berisi focuses on what something is filled with.

In Indonesian, adjectives usually come after the noun.

So:

• barang murah = cheap goods
• stok baru = new stock

This noun + adjective order is very normal in Indonesian.

Barang means goods, items, or merchandise. It is a general word for physical things being sold.

So barang murah means cheap goods/items, not necessarily low-quality goods. It usually just means the price is low.

Stok baru means new stock or new inventory. In a shop context, it usually means goods that have just arrived or are newly available, not necessarily brand-new as products.

So it often refers to freshly restocked items rather than simply “unused” items.

Sedangkan is used to show a contrast between two clauses, often like whereas, while, or on the other hand.

In this sentence:

• Etalase yang satu berisi barang murah, sedangkan etalase yang lain berisi stok baru.

This means the two display cases have different contents, and sedangkan highlights that contrast.

Compared with other connectors:

• dan = and → just adds information
• tetapi/tapi = but → direct contrast
• sedangkan = whereas/while → contrast between two parallel things

Here, sedangkan fits very well because the sentence compares one display case with the other.

It is repeated for clarity and balance:

• Etalase yang satu ... sedangkan etalase yang lain ...

This makes the contrast very clear and sounds neat. Indonesian often repeats nouns in this kind of structure.

You could also hear a shorter version like:

• Etalase yang satu berisi barang murah, sedangkan yang lain berisi stok baru.

That is also natural, because yang lain clearly refers back to etalase.

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

So barang murah can mean:

• cheap goods
• cheap items

Even though English uses a plural noun, Indonesian can leave barang unchanged. If needed, plural can be shown by reduplication:

• barang-barang = items / goods

But in this sentence, plain barang is perfectly natural.

Not exactly. Lain usually means other or different.

In yang lain, it means the other one.

Depending on context, English might translate it as:

• the other
• another
• a different one

But in this sentence, since there are two display cases being contrasted, the other display case is the most natural translation.

Yes. That is a very natural and accurate translation.

A more literal breakdown would be:

• Etalase yang satu = one/the one display case
• berisi = contains
• barang murah = cheap goods
• sedangkan = while/whereas
• etalase yang lain = the other display case
• berisi stok baru = contains new stock

So your translation is a good close match.

It sounds natural and neutral. It is not overly formal, but it is a bit more polished than very casual spoken Indonesian.

In casual speech, someone might say:

• Etalase yang satu isinya barang murah, yang satunya lagi isinya stok baru.

That version is more conversational. The original sentence is still completely natural, especially in writing or careful speech.
