Kompetensi ini perlu.

Malay often leaves out the verb to be in simple statements like this.

So where English says something like This competency is necessary, Malay can simply say:

Kompetensi ini perlu

This is very normal. In Malay, a noun phrase can be followed directly by an adjective or descriptive word without needing a separate is.

Ini means this, and in Malay demonstratives usually come after the noun, not before it.

So:

• kompetensi ini = this competency
• buku ini = this book
• rumah ini = this house

That post-noun position is one of the basic word-order differences from English.

In this sentence, perlu functions like a predicate meaning necessary / needed.

Malay words do not always fit neatly into English-style parts of speech. Perlu can behave a bit like:

• an adjective: necessary
• a modal-like word: need to

For example:

• Kompetensi ini perlu.
  = This competency is necessary.

• Anda perlu belajar.
  = You need to study.

So in your sentence, perlu describes the status of kompetensi ini.

Yes, the natural order is:

Kompetensi ini + perlu

That is:

• topic/subject noun phrase first
• predicate second

A form like Ini kompetensi perlu would not sound natural for standard Malay.

The normal pattern is:

• benda ini penting = this thing is important
• cadangan itu baik = that suggestion is good
• kompetensi ini perlu = this competency is necessary

Usually, no. Adalah is often unnecessary here.

Kompetensi ini perlu is already complete and natural.

You may sometimes see adalah in more formal or bureaucratic writing, but in many everyday and even formal cases, Malay prefers the shorter version without it.

So:

• Kompetensi ini perlu = natural
• Kompetensi ini adalah perlu = possible, but often sounds more formal or stiff

Kompetensi is understandable, but it sounds relatively formal, technical, or professional. It is a borrowing related to competency / competence.

Depending on context, Malay speakers might also use words such as:

• kecekapan = competence, efficiency, proficiency
• kemahiran = skill
• kebolehan = ability

So kompetensi is not wrong, but it may feel more specialized, especially in education, training, HR, or assessment contexts.

Yes, it is grammatically complete.

However, in real usage it can sound a little brief or context-dependent, because perlu often makes people wonder:

• necessary for what?
• necessary in what situation?
• necessary for whom?

Still, short sentences like this are common in notes, slides, evaluation forms, policy statements, and similar contexts where the surrounding topic is already clear.

Yes, you could, but it is slightly different.

• Kompetensi ini perlu = This competency is necessary.
• Kompetensi ini diperlukan = This competency is needed / required.

The word diperlukan is a passive-derived form and feels a bit more explicit and formal. It often suggests that something is required by a system, process, or situation.

So:

• perlu = shorter, simpler, more general
• diperlukan = more formal, often closer to required

Usually it points to a specific item and is often understood as singular: this competency.

But Malay does not mark singular and plural the way English does. Context does a lot of the work.

If you really want to emphasize plural, you might see:

• kompetensi-kompetensi ini

But in natural Malay, repetition for plural is only used when needed. Often context alone is enough.

That depends on context. Kompetensi ini perlu is grammatical, but it sounds fairly formal and abstract.

In everyday speech, a Malay speaker might choose a more familiar noun or make the sentence more specific, for example:

• Kemahiran ini penting.
• Kemahiran ini memang diperlukan.
• Perkara ini perlu.

So your sentence is fine, especially in professional or educational settings, but it is not especially conversational.

Perlu is pronounced approximately per-loo.

A rough guide:

• per: like purr but shorter and lighter
• lu: like loo

In standard Malay, the r is usually pronounced, not dropped.

So the whole word is something like per-loo, with fairly even stress.
