Walaupun sambal itu terlalu pedas, saya tetap memakannya karena enak.

Walaupun means although / even though. It introduces a contrast:

• Walaupun sambal itu terlalu pedas = Although that sambal is too spicy
• saya tetap memakannya = I still eat it

So the sentence sets up a surprising contrast: the sambal is too spicy, but the speaker eats it anyway.

You may also see:

• meskipun = also although / even though
• biarpun = similar, sometimes a bit more informal depending on context

Sambal itu means that sambal.

In Indonesian, demonstratives like ini (this) and itu (that) usually come after the noun:

• sambal itu = that sambal
• rumah itu = that house
• buku ini = this book

This is different from English, where that comes before the noun.

Pedas means spicy.

Terlalu pedas means too spicy, not just spicy.
The word terlalu adds the idea of more than is comfortable, appropriate, or desired.

Compare:

• Sambal itu pedas. = That sambal is spicy.
• Sambal itu sangat pedas. = That sambal is very spicy.
• Sambal itu terlalu pedas. = That sambal is too spicy.

A learner often confuses sangat and terlalu:

• sangat = very
• terlalu = too

Tetap means still / nevertheless / anyway in this sentence.

It emphasizes that the speaker continues to do something despite the problem mentioned earlier:

• Walaupun ... terlalu pedas, saya tetap memakannya
  = Although it is too spicy, I still eat it.

Without tetap, the sentence would still be understandable, but tetap makes the contrast stronger and more natural.

Compare:

• Walaupun pedas, saya memakannya. = Although it’s spicy, I eat it.
• Walaupun pedas, saya tetap memakannya. = Although it’s spicy, I still eat it / I eat it anyway.

Memakannya can be broken down like this:

• makan = eat
• meN- → memakan = to eat, to consume
• -nya = it / him / her, depending on context

So:

• memakannya = eat it

In this sentence, -nya refers to sambal itu.

Because makan begins with m, the meN- prefix becomes mem-, giving memakan.

Using memakan makes the verb explicitly transitive and more formal or complete in style.

• saya makan sambal itu = I eat that sambal
• saya memakannya = I eat it

In everyday Indonesian, makan is extremely common, and people often prefer simpler phrasing:

• Walaupun sambal itu terlalu pedas, saya tetap makan karena enak.
• Walaupun sambal itu terlalu pedas, saya tetap makan sambal itu karena enak.

So memakannya is correct and natural, but slightly more polished or written in feel than plain makan.

Here, -nya means it.

It refers back to sambal itu. So:

• memakannya = eat it

In Indonesian, -nya is very flexible. It can function as:

• a third-person marker: him / her / it
• a possessive marker: his / her / its
• sometimes a definite marker in certain contexts

In this sentence, the meaning is clearly it, because the speaker is eating the sambal.

Indonesian often omits words that are understood from context.

• karena enak literally looks like because delicious
• in natural English, we translate it as because it is delicious

The subject is understood to be the sambal. Indonesian often leaves out subjects or forms of to be when the meaning is obvious.

Compare:

• Sambal itu enak. = That sambal is delicious.
• Saya suka sambal itu karena enak. = I like that sambal because it is delicious.

There is no word equivalent to is here.

Not always. Enak is a broad word meaning something like pleasant, tasty, nice, enjoyable, comfortable, depending on context.

With food, it usually means:

• tasty
• delicious

Examples:

• Makanan ini enak. = This food is delicious.
• Tidurnya enak. = The sleep was comfortable / I slept well.
• Kursinya enak. = The chair is comfortable.

In your sentence, because it is about sambal, enak clearly means delicious / tasty.

The most neutral order is:

• saya tetap memakannya = I still eat it

This follows a common Indonesian pattern:

• subject + adverb + verb

So:

• saya = subject
• tetap = adverb
• memakannya = verb phrase

You may sometimes see different word orders for emphasis, but saya tetap memakannya is the standard, natural order.

Yes. Indonesian is flexible here.

You can say:

• Walaupun sambal itu terlalu pedas, saya tetap memakannya karena enak.

Or:

• Saya tetap memakannya karena enak, walaupun sambal itu terlalu pedas.

Both are grammatical. The first version puts the contrast first, which often sounds a little more dramatic or focused:

• Although it’s too spicy, I still eat it...

The second starts with the main action:

• I still eat it... although it’s too spicy.

It explains the reason for the speaker’s action: the speaker eats it because it is delicious.

So grammatically, karena enak gives the reason for saya tetap memakannya, but semantically enak describes the sambal.

In other words:

• The sambal is delicious.
• That is why the speaker still eats it.

It is natural and correct, but it leans slightly toward a careful or written style because of memakannya.

A more casual spoken version might be:

• Walaupun sambal itu terlalu pedas, saya tetap makan karena enak.
• Walaupun sambalnya terlalu pedas, saya tetap makan karena enak.

You might also hear:

• Meskipun sambalnya kepedasan, saya tetap makan karena enak.

So the original sentence is good Indonesian, especially for learning standard grammar.
