Liputan rangkaian itu luas.

The structure is:

Liputan rangkaian itu + luas

So it is:

subject noun phrase + adjective predicate

A very literal breakdown is coverage network that wide.
Natural English rearranges this as something like That network's coverage is wide or The network coverage is extensive.

Here, liputan means coverage.

Depending on context, liputan can refer to:

• network or signal coverage
• the area reached by a service
• media/news coverage

In this sentence, it most naturally means coverage in the sense of how far a network reaches.

Malay often puts the main noun first and the describing/specifying noun after it.

So:

liputan rangkaian
literally = coverage network

But in natural English, we would usually reverse it and say:

network coverage
or
coverage of the network

This is a very common pattern in Malay, where two nouns are placed together without a word like of.

In Malay, demonstratives like ini and itu usually come after the noun or noun phrase they refer to.

So:

• rangkaian itu = that network
• liputan rangkaian itu = that network coverage / the coverage of that network, depending on context

This is normal Malay word order. English says that network, but Malay says network that.

It most directly means that, but in real sentences it can also make something sound specific/known, which sometimes feels closer to English the.

So depending on context, itu may be translated as:

• that
• the
• or sometimes left untranslated in smoother English

That is why a translation like The network coverage is extensive can still be correct, even though itu literally points to something specific.

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

So:

Liputan rangkaian itu luas
literally has no separate word for is, but it naturally means
The network coverage is wide/extensive

This is very common in Malay, especially with adjectives.

In more formal Malay, you may sometimes see adalah: Liputan rangkaian itu adalah luas

But in everyday usage, leaving it out is more natural.

Because luas is the predicate adjective of the sentence.

It is not directly modifying the noun inside the noun phrase. Instead, it is saying something about the whole subject:

Liputan rangkaian itu = the subject
luas = what is being said about it

So the sentence means that the coverage is broad/extensive.

Luas literally means wide, broad, or spacious, but in this sentence it is better understood as:

• extensive
• broad
• wide in reach

So for network coverage, luas means the coverage extends over a large area.

Yes. Liputan is a flexible word.

For example, it can mean:

• coverage area for a network or service
• news coverage in media
• scope/reach more generally

So learners should not assume it only refers to phone or internet signals. The surrounding words usually tell you which meaning is intended.

Not always. Rangkaian can mean different kinds of network, system, series, or connected arrangement, depending on context.

For example, it may refer to:

• a telecommunications network
• a broadcast network
• a chain or series of connected things
• sometimes even a circuit-like arrangement

In this sentence, it is most naturally understood as some kind of network whose coverage can be described as luas.
