Sekiranya pendawaian rosak, ia hendaklah diperiksa oleh juruelektrik.

Sekiranya means if or in the event that. It is more formal than kalau, and often a bit more formal or literary than jika.

In this sentence, sekiranya pendawaian rosak means if the wiring is damaged.

Roughly:

• sekiranya = formal if
• jika = standard if
• kalau = everyday spoken if

So this sentence sounds suitable for instructions, warnings, or official writing.

Pendawaian means wiring.

It comes from the root dawai, which relates to wire. The pattern peN-...-an often forms a noun connected with a process, system, or result. So pendawaian refers to the wiring system or electrical wiring in general, not just a single wire.

For example:

• dawai = wire
• pendawaian = wiring

In this sentence, it refers to the electrical wiring that may be damaged.

In Malay, a verb like to be is often omitted in simple statements.

So:

• pendawaian rosak literally looks like wiring damaged
• but it means the wiring is damaged

This is completely normal in Malay. You do not need to add a separate word for is in this kind of sentence.

Similar examples:

• Pintu terbuka. = The door is open.
• Kereta itu rosak. = That car is broken.

Ia refers back to pendawaian — the wiring.

So the structure is:

• Sekiranya pendawaian rosak = If the wiring is damaged
• ia hendaklah diperiksa = it must/should be inspected

Malay sometimes repeats the subject with ia in formal writing for clarity. In English, this is also possible: If the wiring is damaged, it should be inspected...

Yes, very often Malay can omit it, especially when the meaning is already clear.

A version without ia would be: Sekiranya pendawaian rosak, hendaklah diperiksa oleh juruelektrik.

However, including ia makes the sentence feel clearer and more complete in formal writing. In official or instructional style, this is quite natural.

So:

• with ia = clearer, formal, explicit
• without ia = also possible, especially when context is obvious

Hendaklah expresses a strong instruction, obligation, or recommendation. In this sentence, it is close to must, should, or ought to, depending on context.

It is more formal than everyday speech. You often see it in:

• regulations
• safety instructions
• manuals
• official notices

So ia hendaklah diperiksa means something like:

• it must be inspected
• it should be inspected

In a safety sentence like this, must be inspected is often the best sense.

Diperiksa is a passive form.

The root is periksa = inspect / examine.

The prefix di- is commonly used to form the passive:

• memeriksa = to inspect, examines
• diperiksa = to be inspected, is inspected

So:

• Juruelektrik memeriksa pendawaian. = The electrician inspects the wiring.
• Pendawaian diperiksa oleh juruelektrik. = The wiring is inspected by the electrician.

In your sentence, the focus is on the wiring, not on the person doing the action, so the passive is very natural.

Oleh means by, and it introduces the agent in a passive sentence.

So:

• diperiksa oleh juruelektrik = inspected by an electrician

This is the Malay equivalent of an English passive phrase like by a doctor, by a technician, by a teacher, etc.

In many Malay sentences, the agent can be omitted if it is not important. But here it matters, because the sentence specifically says that the wiring should be checked by an electrician, not just by anyone.

Yes, juruelektrik is written as one word.

It means electrician.

The element juru- is used in Malay to form words for a person skilled in or responsible for a certain activity. So juruelektrik is a person who works with electricity — an electrician.

Other examples with juru include:

• jurucakap = spokesperson
• jurulatih = trainer/coach
• juruterbang = pilot

So juruelektrik is a standard profession word.

Yes, definitely.

Several features make it formal:

• sekiranya instead of kalau
• hendaklah instead of a more everyday wording
• passive structure diperiksa oleh...

This kind of sentence sounds like something from:

• a safety notice
• an instruction manual
• official advice
• workplace regulations

A more conversational version might be: Kalau pendawaian rosak, minta juruelektrik periksa.

That is less formal and more like spoken Malay.

Yes. A more active version would be something like:

Sekiranya pendawaian rosak, juruelektrik hendaklah memeriksanya.

This means: If the wiring is damaged, an electrician should inspect it.

Compare the two:

• Passive:
  Sekiranya pendawaian rosak, ia hendaklah diperiksa oleh juruelektrik.
  Focus on the wiring

• Active:
  Sekiranya pendawaian rosak, juruelektrik hendaklah memeriksanya.
  Focus on the electrician

The passive is very common in formal and instructional Malay, especially when the important thing is what must be done to the object.

The sentence has two main parts:

1. Sekiranya pendawaian rosak
   = If the wiring is damaged

2. ia hendaklah diperiksa oleh juruelektrik
   = it must/should be inspected by an electrician

So the structure is:

[Condition] + [main instruction]

More literally:

• Sekiranya = if
• pendawaian = wiring
• rosak = damaged/broken
• ia = it
• hendaklah = must/should
• diperiksa = be inspected
• oleh juruelektrik = by an electrician

This is a very typical Malay pattern for formal conditional instructions.
