Karena talang itu tersumbat, air turun ke teras lebih cepat daripada biasanya.

Karena means because. It introduces the reason:

• Karena talang itu tersumbat = Because the gutter is clogged

Indonesian can put the reason clause first, just like English:

• Karena talang itu tersumbat, air turun ke teras...
• Air turun ke teras... karena talang itu tersumbat.

Both are natural. Putting karena first gives the cause before the result.

Talang means gutter or drain channel, especially one that carries rainwater from a roof.

In this sentence, it refers to the roof gutter, not a general pipe. So talang itu is that gutter or the gutter.

Itu often means that, but in Indonesian it is also commonly used after a noun to make it more specific:

• talang = a gutter
• talang itu = that gutter / the gutter

So here it points to a specific gutter already known in the situation.

This word order is normal in Indonesian:

• rumah itu = that house
• mobil itu = that car
• talang itu = that gutter

Tersumbat means blocked, clogged, or stopped up.

The base idea is sumbat, related to blocking or plugging something. The prefix ter- here often describes a resulting state, not an action done by a named person.

So:

• talang itu tersumbat = the gutter is clogged

This is more like describing its condition than saying who clogged it.

Compare:

• pintu tertutup = the door is closed
• jalan terhalang = the road is blocked
• talang tersumbat = the gutter is clogged

The comma separates the reason clause from the main clause:

• Karena talang itu tersumbat, = because the gutter is clogged,
• air turun ke teras... = water goes down onto the terrace...

This is similar to English when a because clause comes first. In informal writing, Indonesians do not always use punctuation consistently, but this comma is standard and helpful.

Yes. Turun means go down, descend, or fall. With air it is very natural, because water physically moves downward.

So air turun ke teras is literally something like:

• water goes down to the terrace

In natural English, you might translate it as:

• water flows down onto the terrace
• water comes down onto the terrace
• water runs down to the terrace

Indonesian often uses simple motion verbs like turun where English might prefer a more specific verb such as flow or run.

Because ke shows movement toward a destination, while di shows location.

• ke teras = to/onto the terrace
• di teras = on the terrace / at the terrace

Since the water is moving toward the terrace, ke is the correct choice.

Compare:

• Saya pergi ke rumah. = I go to the house.
• Saya di rumah. = I am at home.

Teras usually means terrace, porch, or front veranda, depending on the house and context.

In Indonesian home-related contexts, teras often refers to the covered area just outside the front of the house. So in this sentence, the idea is that water is coming down onto that outside platform/porch area.

This is a comparison phrase.

• lebih cepat = faster / more quickly
• daripada = than
• biasanya = usually / than usual

So:

• lebih cepat daripada biasanya = faster than usual

A useful pattern is:

• lebih + adjective/adverb + daripada + comparison

Examples:

• lebih besar daripada rumah saya = bigger than my house
• lebih lambat daripada kemarin = slower than yesterday
• lebih cepat daripada biasanya = faster than usual

In standard Indonesian, daripada is the usual word for than in comparisons.

• lebih cepat daripada biasanya = faster than usual

Dari often means from, and in casual speech some people do use dari where standard grammar prefers daripada. But for learners, it is best to treat daripada as the normal comparison word after lebih.

So the safest pattern is:

• lebih ... daripada ...

Biasanya means usually, normally, or as usual, depending on context.

In this sentence, daripada biasanya literally means than usual or than it usually does.

Examples:

• Saya biasanya bangun jam 6. = I usually wake up at 6.
• Hari ini lebih ramai daripada biasanya. = Today is busier than usual.

Indonesian adjectives often also function as adverbs without changing form.

So cepat can mean:

• fast as an adjective
• quickly as an adverb

In this sentence, lebih cepat describes how the water comes down, so in English it is best understood as more quickly or faster.

This is very common in Indonesian:

• Dia lari cepat. = He runs fast.
• Mobil itu cepat. = That car is fast.

Yes. A very natural alternative is:

• Air turun ke teras lebih cepat daripada biasanya karena talang itu tersumbat.

This keeps the same meaning but puts the main event first and the reason second.

Indonesian word order is often flexible in this kind of sentence, especially with reason clauses introduced by karena.

It is basically neutral standard Indonesian. Nothing in it is especially slangy or highly formal.

The vocabulary and structure are normal for everyday speech and writing:

• karena = standard
• tersumbat = standard
• daripada biasanya = standard comparison

So it is a good model sentence for learners.

Yes, very likely. Because the sentence mentions a clogged talang (gutter), the air here is naturally understood as rainwater coming from the roof drainage system.

Indonesian often relies on context instead of specifying every detail. So even though the sentence just says air (water), the presence of talang makes the situation clear.
