Saya tidak mau nekat naik motor saat hujan deras, tetapi dia tetap ngotot.

Here mau means to want to or to be willing to.

So Saya tidak mau nekat is literally something like:

• I don’t want to be reckless
• or I’m not willing to take that risk

In Indonesian, mau is very common in everyday speech and often sounds more natural than a more formal word like ingin.

Nekat means doing something recklessly, rashly, or boldly without enough concern for the danger or consequences.

In this sentence, it suggests that riding a motorcycle in very heavy rain would be an unsafe or foolhardy thing to do.

So nekat naik motor means something like:

• to recklessly ride a motorcycle
• to go ahead and ride despite the danger

The word often carries a negative nuance, though sometimes it can also imply daring behavior.

In this sentence, nekat works like a descriptive word after mau, almost like to be reckless or to act recklessly.

Indonesian often allows words like this to function quite flexibly. So:

• Saya tidak mau nekat = I don’t want to be reckless / act recklessly

You do not need an affix here. The structure is natural and idiomatic.

Naik motor is the normal everyday way to say ride a motorcycle or go by motorcycle.

• naik motor = casual, common, everyday
• mengendarai motor = more formal, more explicitly to operate/drive a motorcycle

A native speaker will very often say naik motor in conversation.

Yes. In everyday Indonesian, motor usually means motorcycle, not just motor in the English sense.

So:

• mobil = car
• motor = motorcycle

This is a very common point for English speakers to notice, because the Indonesian meaning is narrower than the English word motor.

Saat means when, at the time when, or during.

Hujan deras means heavy rain or rain falling heavily.

So saat hujan deras means:

• when it’s raining heavily
• during heavy rain

It gives the situation in which the speaker does not want to ride the motorcycle.

Yes, in many cases you could.

For example:

• saat hujan deras
• ketika hujan deras
• waktu hujan deras

All can mean roughly when it’s raining heavily.

However, there are slight differences in feel:

• saat = fairly neutral, a bit neat and standard
• ketika = also standard, sometimes slightly more formal or written
• waktu = very common in speech, often a bit more conversational depending on the sentence

In this sentence, saat sounds completely natural.

In Indonesian, adjectives usually come after the noun.

So:

• hujan deras = heavy rain
• literally rain heavy

This is normal Indonesian word order.

Other examples:

• rumah besar = big house
• air dingin = cold water

Tetapi means but.

It is the fuller form of tapi.

• tetapi = a bit more formal or careful
• tapi = very common in everyday speech

Both are correct. In this sentence, tetapi sounds slightly more polished, but tapi would also be very natural in conversation.

Tetap means still, nevertheless, or kept on.

Ngotot means to insist stubbornly, to be adamant, or to keep pushing one’s opinion or plan.

So dia tetap ngotot means something like:

• but he/she still insisted
• but he/she remained stubbornly adamant
• but he/she kept insisting anyway

The combination gives the idea that despite the speaker’s refusal or the dangerous situation, the other person would not back down.

Not really. Ngotot usually has a somewhat negative nuance.

It suggests that someone is:

• overly insistent
• stubborn
• unwilling to listen
• pushing something too hard

So it is stronger than a neutral word like bersikeras in some situations, and it often sounds more colloquial.

Because of that, dia tetap ngotot gives a sense of annoyance or criticism toward that person.

No, ngotot is fairly informal and conversational.

It is very common in speech and casual writing, but in more formal writing you might choose something like:

• bersikeras
• tetap bersikeras

That said, ngotot is extremely useful because native speakers use it a lot in everyday situations.

Dia can mean either he or she.

Indonesian third-person singular pronouns usually do not show gender. So you need context to know whether the person is male or female.

That is why dia tetap ngotot can mean either:

• he still insisted
• she still insisted

Indonesian does not mark tense the way English does.

So this sentence could refer to:

• a present situation
• a past event
• a general habit

The time is normally understood from context, or from time words if they are added.

For example:

• Kemarin saya tidak mau nekat naik motor saat hujan deras, tetapi dia tetap ngotot.
  = Yesterday, I didn’t want to recklessly ride a motorcycle in heavy rain, but he/she insisted anyway.

Without a time marker, the sentence is tense-neutral.

The order is natural because it builds the idea step by step:

• Saya = I
• tidak mau = do not want / am not willing
• nekat = be reckless / act recklessly
• naik motor = ride a motorcycle
• saat hujan deras = during heavy rain

So the structure is roughly:

I + do not want + to be reckless + by riding a motorcycle + during heavy rain

This is a normal Indonesian way to express the idea.

Yes. A very literal translation may sound a little stiff in English. More natural English versions could be:

• I didn’t want to risk riding a motorcycle in heavy rain, but he/she insisted anyway.
• I wasn’t willing to ride a motorcycle in such heavy rain, but he/she kept insisting.
• I didn’t want to be reckless and ride the motorcycle in heavy rain, but he/she was adamant.

This is useful because Indonesian often expresses ideas in ways that are best translated more naturally rather than word-for-word.
