Jangan menyerah sekarang.

Because jangan is the normal word for a negative command in Indonesian.

• Jangan menyerah sekarang. = Don’t give up now.
• Dia tidak menyerah sekarang. = He/She is not giving up now.

So:

• jangan = don’t ...
• tidak = not in a statement

Yes. In Indonesian, commands often omit the subject. The understood subject is usually you.

So Jangan menyerah sekarang naturally means Don’t give up now without needing kamu.

You can add a subject, but it usually sounds more emphatic:

• Jangan menyerah sekarang. = neutral, natural
• Kamu jangan menyerah sekarang. = You don’t give up now

If you are talking to more than one person, context may already make that clear, or you can say kalian.

Menyerah means to give up, to surrender, or to stop resisting.

In this sentence, it is most likely the motivational meaning give up, not literal surrender in a war or fight.

So it could be used when someone is struggling, tired, discouraged, or thinking of quitting.

For learners, it is best to memorize menyerah as a complete verb meaning give up / surrender.

It is historically related to serah, but in real everyday Indonesian, menyerah is the form you will most often use for this meaning.

Some related forms are:

• menyerah = give up, surrender
• menyerahkan = hand over, submit something
• berserah (diri) = surrender oneself, entrust oneself

So menyerah and menyerahkan are related, but they do not mean the same thing.

Because Indonesian word order is fairly flexible with time expressions, and putting sekarang at the end sounds very natural here.

• Jangan menyerah sekarang. = natural, common
• Sekarang jangan menyerah. = also possible, but with slightly different emphasis

Ending with sekarang puts focus on the timing: don’t give up now.

It can mean either, depending on context and tone.

In this sentence, sekarang usually has the sense of:

• now
• right now
• at this point

So the speaker is saying this is not the moment to give up.

Grammatically, it is an imperative sentence, so it has the form of a command.

But in real life, it often sounds like encouragement rather than a strict order.

For example, a friend might say Jangan menyerah sekarang to mean:

• keep going
• don’t quit yet
• you’re close

So the exact feeling depends a lot on the speaker’s tone.

You can soften it in several common ways:

• Jangan menyerah sekarang, ya. = softer, reassuring
• Tolong jangan menyerah sekarang. = Please don’t give up now
• Jangan menyerah dulu. = Don’t give up yet

Of these, dulu is especially common when you mean not yet / wait a bit / keep trying.

Yes. Without a subject, it can refer to one person or more than one person. Context usually tells you which.

If you want to be explicit:

• Kamu jangan menyerah sekarang. = one person
• Kalian jangan menyerah sekarang. = more than one person

But the version without a subject is very normal.

Not if you mean Don’t give up now.

For a negative command, Indonesian uses jangan, not tidak.

So:

• Jangan menyerah sekarang. = correct for Don’t give up now
• Tidak menyerah sekarang = not a natural standalone command

A form with tidak would normally belong in a statement, not an instruction.

Yes, you could say Jangan putus asa sekarang, but the nuance is a little different.

• menyerah = give up, stop trying, surrender
• putus asa = lose hope, become hopeless

So:

• Jangan menyerah sekarang. = don’t quit now
• Jangan putus asa sekarang. = don’t lose hope now

They are similar in motivational contexts, but menyerah focuses more on the action of quitting, while putus asa focuses more on the feeling of hopelessness.
