Asingkan sisa organik itu.

Yes. Asingkan is an imperative form, so the sentence is giving a command or instruction:

Asingkan sisa organik itu.
= Separate that organic waste.

Malay often uses this kind of direct verb-first structure for instructions, notices, and workplace or household directions.

Asingkan means separate, sort out, or set apart.

It comes from the idea of making something separate from other things. In practical contexts like recycling, rubbish sorting, or food waste, asingkan often means:

• separate
• sort into a different category
• keep apart

So in this sentence, it means you should put the organic waste in its own group or container.

This is a very common learner question.

Mengasingkan is the normal active verb form used in a full statement, for example:

• Saya mengasingkan sisa organik itu.
  = I separate / am separating that organic waste.

But in commands, Malay usually drops the meN- prefix. So:

• statement: mengasingkan
• command: asingkan

This is very common in Malay imperatives:

• membuka → buka = open!
• mengambil → ambil = take!
• memasukkan → masukkan = put in!
• mengasingkan → asingkan = separate!

The suffix -kan often makes a verb more clearly transitive, meaning it acts on an object.

Here, asingkan means something like:

• separate it/them
• make it separate
• put it apart

Without going too deeply into grammar, -kan helps show that the action is being done to something. In this sentence, the thing being acted on is:

sisa organik itu = that organic waste

So asingkan works naturally with an object.

• sisa = waste, residue, leftovers, remains
• organik = organic

Together, sisa organik means organic waste.

In environmental or household contexts, this usually refers to things like:

• food scraps
• plant matter
• biodegradable waste

So the phrase is a normal Malay noun phrase for organic waste.

Because Malay usually puts adjectives and many modifiers after the noun.

So:

• sisa organik = literally waste organic
• natural English = organic waste

This is normal Malay word order. More examples:

• rumah besar = big house
• air panas = hot water
• buah segar = fresh fruit

So sisa organik follows standard Malay structure.

Itu usually means that, and it comes after the noun phrase it modifies.

So:

• sisa organik itu = that organic waste

Depending on context, it can sometimes sound like the in natural English, especially when the speaker refers to something already known or visible.

Malay places demonstratives after the noun:

• buku itu = that book
• orang itu = that person
• sisa organik itu = that organic waste

Because Malay demonstratives normally come after the noun, unlike English.

Compare:

• English: that organic waste
• Malay: sisa organik itu

The order is:

noun + modifier + itu/ini

Examples:

• rumah itu = that house
• kereta baru itu = that new car
• sisa organik itu = that organic waste

So this word order is completely normal.

Yes. In commands, the subject is usually understood, not spoken.

So Asingkan sisa organik itu really means:

• (You) separate that organic waste.

Malay often leaves out pronouns when they are obvious from context, especially in instructions and imperatives.

By itself, it is fairly direct and neutral. It sounds natural for:

• instructions
• signs
• workplace directions
• labels
• household rules

If you want to make it more polite, you can add words like:

• Tolong asingkan sisa organik itu.
  = Please separate that organic waste.

• Sila asingkan sisa organik itu.
  = Please separate that organic waste. / Kindly separate that organic waste.

So the original sentence is not rude, but it is definitely a plain instruction.

Yes. Sisa can mean:

• remainder
• leftover
• residue
• waste

Its exact meaning depends on context.

For example:

• sisa makanan = food leftovers
• sisa buangan = waste material
• sisa organik = organic waste

So in this sentence, because of the environmental/recycling context, waste is the most natural translation.

A full statement would usually use mengasingkan instead of asingkan. For example:

• Saya mengasingkan sisa organik itu.
  = I separate / am separating that organic waste.

• Mereka mengasingkan sisa organik itu.
  = They separate that organic waste.

So the command form and statement form are related, but they use different verb shapes.

A simple guide is:

ah-SING-kahn SEE-sah or-gah-NIK ee-too

A few notes:

• s is like English s, never like z
• g in organik is a hard g, as in go
• k at the end of a syllable in Malay can be lightly released or even sound a bit clipped in natural speech
• stress in Malay is usually not as strong or dramatic as in English

So if you say it clearly and evenly, you will be understood.
