Defibrilator boleh digunakan asalkan pengajar memberi arahan.

Asalkan means as long as, provided that, or on condition that.

In this sentence, it introduces a condition:

• Defibrilator boleh digunakan = the defibrillator can/may be used
• asalkan pengajar memberi arahan = as long as / provided that the instructor gives instructions

So asalkan tells you that the first part is only true if the second part happens.

Boleh can mean both can and may, depending on context.

Here it has the sense of is allowed to / may / can:

• Defibrilator boleh digunakan = The defibrillator may/can be used

In English, both can be used and may be used are possible translations here. Because this is about permission or allowed use, may be used or can be used both fit.

Digunakan is the passive form of gunakan.

Breakdown:

• guna = use
• gunakan = use something
• digunakan = be used

So:

• Defibrilator boleh digunakan = The defibrillator can be used

Malay often uses the passive when the thing affected is the topic of the sentence. In English, this is like using be + past participle:

• is used
• can be used

If you used menggunakan, the sentence would need an active subject:

• Pengajar boleh menggunakan defibrilator = The instructor can use the defibrillator

That is a different structure and slightly different focus.

Yes, the main clause is passive.

• Defibrilator = the thing being talked about
• boleh digunakan = can be used

So the sentence focuses on the defibrillator, not on the person using it.

This is very natural in Malay. The person who uses it is not mentioned, because the important point is the condition under which the device may be used.

Pengajar means instructor, trainer, or teacher.

It is similar to guru, but not exactly the same in every context:

• guru usually means a school teacher
• pengajar often means an instructor or someone giving training or guidance

In this sentence, pengajar sounds appropriate because it suggests someone supervising or instructing the use of the defibrillator.

Memberi arahan means to give instructions or to give directions/orders, depending on context.

Breakdown:

• memberi = to give
• arahan = instruction, order, direction

So:

• pengajar memberi arahan = the instructor gives instructions

In this sentence, it probably means the instructor is guiding the person on what to do.

Because the meaning is different.

• mengajar = to teach
• memberi arahan = to give instructions

In this sentence, the instructor is not necessarily teaching a lesson. They are more specifically giving directions about when or how the defibrillator should be used.

So memberi arahan is the better choice for this meaning.

Malay does not normally use articles like a, an, or the.

So:

• Defibrilator can mean a defibrillator or the defibrillator
• pengajar can mean an instructor or the instructor

You understand which one is meant from context.

That is why the sentence can be translated in different natural ways in English, such as:

• A defibrillator can be used as long as the instructor gives instructions
• The defibrillator may be used provided the instructor gives instructions

Yes. Malay is often flexible with this kind of conditional phrase.

You could say:

• Asalkan pengajar memberi arahan, defibrilator boleh digunakan.

This means the same thing:
As long as the instructor gives instructions, the defibrillator can be used.

Putting asalkan first gives more emphasis to the condition.

Yes.

• beri = give
• memberi = to give

memberi is the verb form with the meN- prefix, which is a very common active verb pattern in Malay.

So:

• beri arahan can appear in casual speech
• memberi arahan is more standard and complete

Both relate to the same basic verb beri.

Yes, that is a reasonable translation.

But asalkan is slightly more specific than plain if. It usually means:

• as long as
• provided that
• on the condition that

So if is possible in English, but provided that or as long as often matches the Malay nuance better.

It is a borrowed word, adapted from defibrillator.

Malay uses many international technical and medical terms, often with spelling adjusted to fit Malay spelling patterns. So:

• English: defibrillator
• Malay: defibrilator

This is very common in scientific, medical, and technical vocabulary.
