Tiket masuk juga berlaku untuk undian.

Tiket means ticket, and masuk means enter / go in.

So tiket masuk literally means entry ticket or admission ticket.
In English, we often use a noun + noun combination like entry ticket or admission ticket. In Indonesian, it is very common to use a noun followed by another word that describes its function.

So here:

• tiket = ticket
• masuk = enter / entrance
• tiket masuk = ticket for entering

It is a normal fixed phrase.

Because Indonesian often does not need a separate word for is / are in the way English does.

But in this sentence, there is actually already a main verb: berlaku.

So the structure is:

• Tiket masuk = the admission ticket / admission tickets
• juga = also
• berlaku = is valid / applies
• untuk undian = for the raffle / drawing

So this is not really a sentence missing is. The verb is berlaku.

A natural English gloss is:

• The admission ticket is also valid for the raffle.

Here, berlaku means something like:

• to be valid
• to apply
• to be in effect

In this sentence, berlaku untuk means to be valid for or to apply to.

So:

• Tiket masuk juga berlaku untuk undian
  = The admission ticket is also valid for the raffle/drawing.

This suggests the ticket is not only for entering, but can also be used in relation to the undian.

Yes. Berlaku untuk is a very common pattern.

It often means:

• applies to
• is valid for
• is good for

Examples:

• Promo ini berlaku untuk semua pelanggan.
  = This promotion applies to all customers.

• Tiket ini berlaku untuk dua orang.
  = This ticket is valid for two people.

So in your sentence, berlaku untuk undian means the ticket also applies to / counts for the raffle.

Untuk often means for.

After berlaku, untuk shows what something is valid for or applies to.

So:

• berlaku untuk undian = valid for the raffle / applies to the raffle

You should think of berlaku untuk as a set expression.

It would sound less natural to try to translate English word-for-word with other prepositions unless the context changes.

Undian usually refers to:

• a drawing
• a raffle
• a lottery-style draw

The exact English translation depends on context.

For example:

• in a store promotion, undian is often a raffle or prize draw
• in other contexts, it can be a lottery
• in a more general sense, it is a drawing by chance

So here, undian most likely means a raffle or prize drawing.

Yes, juga usually means also or too.

In this sentence, it comes after the subject:

• Tiket masuk juga berlaku untuk undian.

This placement is very natural. It means the admission ticket has an additional function: it is not only for entry, but also for the raffle.

You may also hear slightly different placements in Indonesian, but this version is standard and clear.

It can be either, depending on context.

Indonesian nouns usually do not change form for singular vs. plural. So:

• tiket masuk can mean an admission ticket
• or admission tickets

Context tells you which one is meant.

In English, a translator often chooses singular or plural based on the situation. If this is a general notice, English might also say:

• Admission tickets are also valid for the raffle.

If it refers to one ticket type as a general category, English might say:

• The admission ticket is also valid for the raffle.

Because Indonesian does not usually use articles like the, a, or an.

So tiket masuk could mean:

• an admission ticket
• the admission ticket
• admission tickets

Again, context decides.

This is one of the biggest differences from English. Indonesian often leaves definiteness unstated unless it really needs to be made clear.

Yes, that is the most likely meaning.

The sentence suggests that the admission ticket is not only used to enter, but also counts for the undian.

A very natural English interpretation would be:

• Your admission ticket also serves as a raffle ticket.
• The admission ticket is also valid for the raffle.

So the idea is not just abstract validity; it usually implies participation or eligibility in the draw.

Not exactly.

Berlaku untuk does not literally mean is included in. It means more like:

• is valid for
• applies to
• counts for

So a better translation is:

• The admission ticket is also valid for the raffle.
• The admission ticket also counts for the raffle.

If you wanted to say included in, Indonesian would usually use a different expression, depending on the context.

Yes. Berlaku has a few related meanings, depending on context.

Common ones are:

• to be valid
• to apply
• to be in force
• to take effect

Examples:

• Aturan ini berlaku mulai besok.
  = This rule takes effect starting tomorrow.

• Diskon ini berlaku sampai akhir bulan.
  = This discount is valid until the end of the month.

So in your sentence, the meaning is the valid / applies sense.

The structure is:

• Tiket masuk = subject
• juga = adverb
• berlaku = verb
• untuk undian = prepositional phrase

So:

Subject + adverb + verb + prepositional phrase

That gives:

• Tiket masuk juga berlaku untuk undian.

A very literal breakdown would be:

• admission ticket + also + is valid/applies + for raffle

This is a very typical Indonesian sentence pattern.
