Saya telanjur janji untuk datang, jadi saya tidak enak kalau batal.

Telanjur means something like already gone so far that it would be difficult, awkward, or regrettable to change course.

In Saya telanjur janji untuk datang, it suggests:

• I already made the promise
• it is now too late to easily take it back
• there is a slight sense of regret, commitment, or being stuck with it

So it is stronger than just sudah.

Compare:

• Saya sudah janji untuk datang. = I already promised to come.
• Saya telanjur janji untuk datang. = I’ve already promised to come, and now I kind of can’t back out comfortably.

In formal Indonesian, berjanji is the full verb meaning to promise.

But in everyday speech, Indonesians very often use janji by itself as a verb:

• Saya janji. = I promise.
• Dia janji mau datang. = He/She promised to come.

So in this sentence, telanjur janji is a very natural, conversational way to say already promised.

A more formal version could be:

• Saya telanjur berjanji untuk datang...

That is grammatical too, but it sounds a bit more formal or careful.

Here, untuk introduces the action that was promised:

• janji untuk datang = promise to come

So untuk datang explains what the promise was about.

In everyday Indonesian, untuk is often omitted after janji, especially in speech:

• Saya telanjur janji datang.

That also sounds natural.

Very roughly:

• janji untuk datang = a little clearer / slightly more explicit
• janji datang = very common in conversation

Datang means to come or to arrive.

In this sentence, it means to come to the place/event/situation being talked about.

So:

• janji untuk datang = promised to come

It does not specifically mean arrive on time. It simply means show up / come.

No. In this sentence, jadi means so, therefore, or as a result.

So:

• Saya telanjur janji untuk datang, jadi...
• I’ve already promised to come, so...

This is a very common use of jadi in conversation.

Compare:

• Dia jadi dokter. = He/She became a doctor.
• Saya capek, jadi saya pulang. = I’m tired, so I’m going home.

Same word, different meaning from context.

Because enak has more than one meaning.

It can mean:

• delicious / tasty
• pleasant / comfortable / nice
• in some contexts, the opposite tidak enak can mean awkward, bad, guilty, or uncomfortable

In saya tidak enak kalau batal, it means:

• I’d feel bad
• I’d feel awkward
• I’d feel guilty / uncomfortable

So this has nothing to do with food.

This is a very common expression in Indonesian:

• Saya tidak enak sama dia. = I feel bad toward him/her.
• Tidak enak kalau menolak. = It would feel awkward to refuse.

Kalau means if.

Batal means cancelled, called off, or not going through. In this context, it means if I cancel or if I back out.

So:

• saya tidak enak kalau batal = I’d feel bad if I canceled

Even though batal can look a bit like a state word (be canceled), in everyday Indonesian it is very common to use it this way when a person cancels their plan:

• Maaf, saya batal datang. = Sorry, I’m not coming after all / I have to cancel.
• Dia batal ikut. = He/She ended up not joining.

So here batal means cancel my plan to come.

Both kalau and jika can mean if, but they differ in tone:

• kalau = more common in everyday speech
• jika = more formal, more written, more careful

So in this sentence, kalau sounds natural and conversational.

A more formal version would be:

• ...jadi saya tidak enak jika batal.

That is correct too, but less casual.

Indonesian often repeats subjects when it helps keep the sentence clear and natural.

So:

• Saya telanjur janji untuk datang, jadi saya tidak enak kalau batal.

The second saya makes it clear that I am the one who would feel bad.

Could you say:

• Saya telanjur janji untuk datang, jadi tidak enak kalau batal.

Yes, in conversation that can work, because the subject is understood. But the full version with the second saya sounds very normal and clear.

It is natural everyday Indonesian. It is not slang, but it is also not especially formal.

A few parts make it sound conversational:

• janji instead of berjanji
• kalau instead of jika
• tidak enak as an everyday expression

A more formal version might be something like:

• Saya telanjur berjanji untuk datang, jadi saya merasa tidak enak jika membatalkannya.

That is more formal and more explicit, but the original sentence is probably what you would hear more often in normal speech.

The sentence expresses more than just a factual statement. It carries a social and emotional nuance:

• I already committed myself
• canceling would feel socially awkward
• I would feel bad because I gave my word

So it is not just I can’t cancel in a physical sense. It is more like:

• I really shouldn’t cancel now
• It would feel wrong/awkward to back out

That feeling is very important in Indonesian, especially in phrases like tidak enak. It often reflects concern about politeness, social obligation, and other people’s feelings.

Not exactly.

That translation is a little too strong.

The Indonesian sentence does not literally say there is no choice. It says:

• I already promised to come
• therefore I would feel bad if I canceled

So the idea is closer to:

• I’ve already promised to come, so I’d feel bad canceling.
• I already said I’d come, so it would be awkward for me to back out.

It suggests social pressure and personal discomfort, not absolute impossibility.

Yes. Telanjur is very common and often shows that something has already happened and now cannot easily be undone.

Examples:

• Saya telanjur beli. = I already bought it, and now it’s too late.
• Dia telanjur marah. = He/She already got angry.
• Kami telanjur berangkat. = We already left / had already set off.

Very often, telanjur carries one of these feelings:

• too late to change
• regret
• unavoidable continuation
• stuck with the consequence

That is exactly the nuance it adds in your sentence too.
