Rak pameran disusun mengikut senarai bacaan sedemikian rupa sehingga mudah digunakan.

Disusun is the passive form of susun (to arrange).

• menyusun = to arrange / arranging someone or something
• disusun = is arranged / are arranged

So:

• Kakitangan menyusun rak pameran. = The staff arrange the display shelves.
• Rak pameran disusun... = The display shelves are arranged...

The sentence focuses on the shelves, not on who arranged them, so the passive is natural here.

In Malay, the agent of a passive sentence is often left out if it is unknown, obvious, or unimportant.

So Rak pameran disusun... simply means The display shelves are arranged...

If you wanted to mention who did it, you could add oleh:

• Rak pameran disusun oleh pustakawan. = The display shelves are arranged by the librarian.

But in many real sentences, oleh is omitted because the identity of the doer does not matter.

Malay noun phrases usually put the main noun first and the describing noun after it.

So:

• rak = rack / shelf
• pameran = display / exhibition

Together, rak pameran means display rack or display shelf.

This is the opposite of typical English word order:

• English: display shelf
• Malay: rak pameran

The first word is the thing itself; the second word tells you what kind.

It can be either singular or plural, depending on context.

Malay nouns usually do not change form for plural the way English nouns do. So:

• rak pameran can mean display shelf or display shelves

Context tells you which is more natural. In this sentence, English often translates it as display shelves, but the Malay form stays the same.

If you really wanted to emphasize plurality, Malay can use reduplication:

• rak-rak pameran

But that is often unnecessary.

Here mengikut means according to, following, or in accordance with.

So:

• mengikut senarai bacaan = according to the reading list

It shows the basis or pattern used to arrange the shelves.

A close English paraphrase would be:

• arranged according to the reading list
• arranged following the reading list

This is a very common question.

In this sentence, mengikut is the right choice because it means according to or in accordance with.

• mengikut senarai bacaan = according to the reading list

Mengikuti often has a more direct sense of following, attending, or taking part in something:

• mengikuti kelas = to attend a class
• mengikuti perkembangan = to follow developments
• mengikuti seseorang = to follow someone

So in this sentence, mengikut sounds more natural than mengikuti.

Senarai bacaan means reading list.

Breakdown:

• senarai = list
• bacaan = reading / things to be read / reading material

Bacaan is a noun formed from baca (to read). In this phrase, you need a noun, not a verb.

So:

• baca = read
• membaca = to read / reading as an action
• bacaan = reading matter / reading material / readings

That is why senarai bacaan means something like list of readings or reading list.

This is a somewhat formal expression meaning:

• in such a way that
• so ... that

Breakdown:

• sedemikian = such / like that
• rupa = form / manner / way
• sehingga = until / so that / to the point that

Together, sedemikian rupa sehingga means in such a way that...

So the sentence is saying the shelves are arranged according to the reading list in such a way that they are easy to use.

This expression sounds more formal or written than everyday conversation.

Because the meaning is slightly different.

• supaya usually expresses purpose: so that / in order that
• sehingga here expresses result: to the point that / so that, with the result that

So:

• ... supaya mudah digunakan = arranged that way so that they will be easy to use
• ... sedemikian rupa sehingga mudah digunakan = arranged in such a way that they are easy to use

The original sentence sounds more formal and more descriptive of the manner and result, not just the intention.

Both are possible, but mudah digunakan is very natural and concise.

• mudah digunakan = easy to use
• mudah untuk digunakan = easy to use

The version without untuk is often smoother in formal written Malay.

Also, digunakan is passive here:

• digunakan = used / to be used

So literally, mudah digunakan is something like easy to be used, though in natural English we simply say easy to use.

Yes.

Just like disusun comes from susun, digunakan comes from gunakan.

• menggunakan = to use
• digunakan = to be used / used

After mudah, Malay often uses this passive-style wording:

• mudah digunakan = easy to use
• sukar difahami = difficult to understand
• senang dilihat = easy to see

So yes, the sentence contains two di- forms:

• disusun = are arranged
• digunakan = used / to be used

Yes, Malay is being economical here.

The phrase mudah digunakan refers back to rak pameran. In other words, the shelves are arranged in a way that makes them easy to use.

Malay often does not repeat the subject if it is already clear from context.

So the structure is roughly:

• Rak pameran disusun ... sehingga [rak pameran itu] mudah digunakan.

But repeating rak pameran would sound heavier and less natural, so it is omitted.

Yes, it sounds fairly formal and written, especially because of sedemikian rupa.

A more everyday version might be something like:

• Rak pameran disusun mengikut senarai bacaan supaya mudah digunakan.
• Rak pameran disusun mengikut senarai bacaan agar mudah digunakan.

These are simpler and more conversational.

The original sentence is perfectly good Malay, but it has a more polished, explanatory style.
