Tukang bangunan membawa bahan bangunan.

A natural word-by-word breakdown is:

• tukang = a worker, craftsman, repair person, or someone whose job is a certain practical task
• bangunan = building / construction
• membawa = to bring, carry, take
• bahan = material, ingredient, substance
• bahan bangunan = building materials / construction materials

So:

• tukang bangunan = construction worker / builder
• membawa bahan bangunan = carries or brings building materials

The sentence structure is very straightforward:

• subject: tukang bangunan
• verb: membawa
• object: bahan bangunan

Because it appears in two different noun phrases:

• tukang bangunan = construction worker
• bahan bangunan = building materials

In both cases, bangunan helps specify what kind of worker or what kind of material is meant.

You can think of it like English phrases such as:

• office worker
• school bus
• building materials

The repeated word is not strange in Indonesian. It just happens that both the worker and the materials are related to construction.

More or less, yes.

A very literal interpretation is something like worker related to buildings/construction, but the natural English meaning is:

• construction worker
• builder

So even if the literal parts seem simple, the whole phrase is best learned as a common expression: tukang bangunan.

Not always. Tukang is a very common Indonesian word for someone who does a practical job, trade, craft, or service.

Depending on context, it can mean things like:

• craftsman
• repairman
• worker
• handyman
• seller/vendor in some expressions

Examples:

• tukang kayu = carpenter
• tukang cukur = barber
• tukang ojek = motorcycle taxi driver
• tukang bangunan = construction worker

So tukang is flexible, and the word after it tells you what kind of person it is.

Indonesian usually does not require articles like a, an, or the.

So Tukang bangunan membawa bahan bangunan could mean:

• A construction worker carries building materials
• The construction worker carries the building materials

The exact English article depends on context, but Indonesian often leaves that unstated.

This is very normal. Learners often want to insert a/the, but Indonesian generally does not work that way.

The verb membawa does not change form for tense the way English verbs do.

So membawa can mean:

• carries
• is carrying
• carried
• will carry

depending on context.

Without any time word, learners often translate it as a simple present:

• The construction worker carries building materials

But it could also be understood as present/progressive in the right situation:

• The construction worker is carrying building materials

If you want to make time clearer in Indonesian, you usually add words such as:

• sedang = currently
• tadi = earlier
• kemarin = yesterday
• akan = will

For example:

• Tukang bangunan sedang membawa bahan bangunan. = The construction worker is carrying building materials.

It can be either, depending on context.

Bahan bangunan may mean:

• building material
• building materials

In English, building materials is often the most natural translation here.

Indonesian nouns usually do not have separate singular and plural forms unless the speaker wants to emphasize plurality. Context does most of the work.

If needed, Indonesian can show plural with reduplication:

• bahan-bahan bangunan = building materials

But in many cases, just bahan bangunan is enough.

In Indonesian noun phrases, the main noun often comes first, followed by a word that describes or limits it.

So:

• tukang bangunan = worker of construction / construction worker
• bahan bangunan = material for building / building material

This is different from English, where the describing noun often comes first:

• construction worker
• building materials

So Indonesian often feels a bit like:

• worker construction
• materials building

That is a useful pattern to notice.

By itself, bangunan commonly means building.

Example:

• Itu bangunan baru. = That is a new building.

But in combinations like these, it helps create related meanings:

• tukang bangunan = construction worker
• bahan bangunan = building materials

So the word keeps its connection to buildings/construction, but the whole phrase should be understood as a unit.

The base word is bawa, which means bring or carry.

With the prefix meN-, it becomes membawa.

This prefix often forms active verbs. So:

• bawa = bring/carry
• membawa = to bring / to carry

For a beginner, the most important thing is simply to recognize membawa as the normal active verb form used in sentences like this one.

Yes.

Depending on context, membawa can be translated as:

• bring
• carry
• sometimes even take along

In this sentence, both carries building materials and brings building materials are possible translations.

English chooses between bring and carry more specifically depending on movement and viewpoint, but Indonesian membawa is broader.

A simple pronunciation guide is:

• Tukang ≈ too-kahng
• bangunan ≈ bahng-oo-nan
• membawa ≈ mem-bah-wah
• bahan ≈ bah-han
• bangunan ≈ bahng-oo-nan

A few helpful points:

• ng in tukang and bangunan is like the ng in sing
• a is usually like a in father, not like the English name-letter A
• Indonesian stress is usually not extremely strong, so say it fairly evenly

A rough full pronunciation:

• too-kahng bahng-oo-nan mem-bah-wah bah-han bahng-oo-nan

Yes, often you can.

• tukang bangunan = construction worker / builder
• pekerja bangunan = construction worker

Both are understandable. In many everyday situations, tukang bangunan is very common and natural.

The nuance is that tukang often sounds like a practical skilled worker or tradesperson, while pekerja is a broader word meaning worker.

So tukang bangunan is a very useful phrase to learn as a standard expression.

It is a complete and grammatical Indonesian sentence.

It is a little simple and generic, so it does have a textbook feel, but it is still perfectly natural. Indonesian often allows short, context-based sentences like this:

• Tukang bangunan membawa bahan bangunan.
• Guru membaca buku.
• Anak itu makan nasi.

So while the sentence is clearly made for learning, there is nothing wrong or unnatural about it.
