Kalau laci meja ini macet lagi, saya akan memanggil tukang besok pagi.

Kalau introduces a condition, so here it means if.

• Kalau laci meja ini macet lagi = If this desk drawer gets jammed again
• It is very common in everyday Indonesian.

A few related words:

• kalau = common, conversational if
• jika = more formal if
• bila = also if, often more formal/literary

So in this sentence, kalau sets up the condition for what happens next.

Indonesian noun phrases usually go in this order:

noun + noun/modifier + demonstrative

So:

• laci = drawer
• meja = desk/table
• ini = this

That gives laci meja ini, meaning this desk drawer or the drawer of this desk.

A useful pattern:

• buku saya ini = this book of mine
• rumah besar itu = that big house

So ini normally comes at the end of the noun phrase, not before the noun as in English.

Literally, meja often means table, but in context it can also mean desk.

Because the sentence mentions a drawer, English naturally translates it as desk drawer. Indonesian often leaves that kind of distinction to context.

So:

• meja = table / desk
• laci meja ini = this table’s drawer / this desk drawer

Yes, macet is very often used for traffic jammed or traffic congestion, but it can also mean jammed, stuck, or not working smoothly for things.

In this sentence:

• laci ... macet = the drawer is jammed/stuck

So macet can be used for:

• traffic: Jalanan macet = The roads are jammed
• machines/objects: Pintu macet = The door is stuck
• a drawer: Laci macet = The drawer is jammed

Here lagi means again.

So:

• macet = jammed/stuck
• macet lagi = jammed again / gets stuck again

This is a very common use of lagi:

• hujan lagi = raining again
• rusak lagi = broken again
• terlambat lagi = late again

In this sentence, it suggests this has happened before.

Akan marks the future, similar to will in English.

• saya akan memanggil tukang = I will call/get a repairman

But in Indonesian, akan is often optional if the future time is already clear from context.

Because the sentence already has besok pagi (tomorrow morning), many speakers could also say:

• Kalau laci meja ini macet lagi, saya memanggil tukang besok pagi.

In natural everyday Indonesian, though, many people would more likely say:

• ... saya panggil tukang besok pagi.

So akan is correct, but not always required.

Memanggil basically means to call, to summon, or to ask someone to come.

In this sentence, it does not have to mean shouting for someone. It means something like:

• call for
• get
• summon
• sometimes contact and ask to come

So saya akan memanggil tukang means:

• I will call a repairman
• I will get a repairman
• I will have a repairman come

If you specifically wanted to say phone someone, Indonesian often uses:

• menelepon
• menelpon
• telepon

Tukang is a very common word for a skilled worker, tradesperson, or repair person. The exact meaning depends heavily on context.

In this sentence, since the problem is a jammed drawer, tukang most naturally means something like:

• repairman
• handyman
• carpenter, depending on the situation

Other examples:

• tukang kayu = carpenter
• tukang ledeng = plumber
• tukang listrik = electrician
• tukang servis = repair technician

So on its own, tukang can feel a bit general, but in real Indonesian that is very normal.

In this sentence, besok pagi most naturally goes with the main action:

• saya akan memanggil tukang besok pagi
• I will call the repairman tomorrow morning

So the meaning is: If this desk drawer gets jammed again, I’ll call a repairman tomorrow morning.

It does not normally mean:

• If the drawer gets jammed again tomorrow morning...

If you wanted that meaning more clearly, you would usually place the time expression inside the kalau clause:

• Kalau besok pagi laci meja ini macet lagi, ...

Yes. Indonesian allows either order.

Original:

• Kalau laci meja ini macet lagi, saya akan memanggil tukang besok pagi.

Reversed:

• Saya akan memanggil tukang besok pagi kalau laci meja ini macet lagi.

Both are correct. Starting with the kalau clause puts more focus on the condition first.

Yes, aku is possible, but it changes the tone.

• saya = neutral, polite, standard
• aku = more personal, informal, intimate

So:

• saya akan memanggil tukang sounds neutral and broadly appropriate
• aku akan memanggil tukang sounds more casual and personal

In learning materials, saya is often used because it is safer in many situations.

No, Indonesian nouns usually do not change form for singular vs. plural.

So:

• laci can mean drawer or drawers
• tukang can mean repairman or repairmen

In this sentence, context strongly suggests singular:

• one drawer
• one repair person

If Indonesian needs to make plurality clear, it can use:

• context
• numbers
• reduplication

For example:

• laci-laci = drawers
• dua tukang = two repairmen/workers
