Kalau Anda kehilangan struk belanja, petugas bisa meminta Anda kembali ke loket.

Yes. Kalau here means if.

So:

• Kalau Anda kehilangan struk belanja... = If you lose your shopping receipt...

A few nuance points:

• kalau is very common in everyday Indonesian
• it can also sometimes feel like when in context, depending on how likely the situation is
• compared with jika, kalau is usually a bit more conversational and natural in speech

So in this sentence, kalau is a normal, natural way to introduce a condition.

Anda is the polite/formal word for you.

It is commonly used:

• in customer service
• in announcements
• in formal writing
• when speaking respectfully to someone you do not know well

Since this sentence sounds like a rule, instruction, or service-related statement, Anda fits very well.

Also, Anda is often capitalized in standard writing as a sign of respect.

Kehilangan means to lose or to misplace something.

It comes from the root hilang, which means lost or disappear.

Compare:

• hilang = lost / gone
• kehilangan = to lose something

So:

• Saya kehilangan dompet. = I lost my wallet.
• Anda kehilangan struk belanja. = You lost your shopping receipt.

This is a very useful pattern in Indonesian: ke-...-an can form words related to experiencing a state or event. In this case, kehilangan is the standard verb for lose.

Usually it means lose the receipt or misplace the receipt.

It suggests that the receipt existed, and then it was no longer in your possession.

So it is closer to:

• you lost the receipt
• you misplaced the receipt

rather than simply:

• you do not have a receipt

If you wanted to say you do not have a receipt, that would be a different idea, such as Anda tidak punya struk.

Literally:

• struk = receipt
• belanja = shopping / purchase

So struk belanja means shopping receipt or purchase receipt.

In many contexts, people may just say struk if the meaning is already clear.

Depending on region and situation, you may also hear words like:

• nota
• bon

But struk is very common, especially for store or cashier receipts.

Petugas means something like:

• staff member
• attendant
• officer
• clerk

The exact English translation depends on context.

In this sentence, petugas probably refers to a staff member at a service counter or checkout area. It is a general and useful word for someone whose job is to assist, monitor, or process customers.

It breaks down like this:

• bisa = can / may / be able to
• meminta = ask / request
• Anda = you
• kembali ke loket = return to the counter

So the structure is:

• petugas bisa meminta Anda kembali ke loket
• the staff can ask you to return to the counter

A very important pattern here is:

• meminta + person + verb/action

So:

• meminta Anda kembali = ask you to return
• meminta saya menunggu = ask me to wait

Indonesian does not always need a separate word like to before the second verb.

Not necessarily. The sentence is already correct without it.

These are both possible:

• petugas bisa meminta Anda kembali ke loket
• petugas bisa meminta Anda untuk kembali ke loket

The version without untuk is very natural and common.

The version with untuk can sound a little more explicit, but the meaning is basically the same:

• ask you to return to the counter

Here, kembali means back or return.

So:

• kembali ke loket = return to the counter / go back to the counter

In other contexts, kembali can also mean again:

• coba kembali = try again

So kembali can mean either back/return or again, and context tells you which one is intended.

In this sentence, because it is followed by ke loket, the meaning is clearly return to the counter.

Loket usually means a service counter, ticket window, or booth where staff deal with customers.

Examples:

• ticket counter
• payment window
• customer service counter

So ke loket means to the counter or to the service desk/window.

It is more specific than a general table or desk. It usually refers to an official customer-service point.

The comma separates the if-clause from the main clause.

So the structure is:

• Kalau Anda kehilangan struk belanja, = If you lose the receipt,
• petugas bisa meminta Anda kembali ke loket. = the staff can ask you to return to the counter.

This is similar to English, where a comma is often used after an introductory if clause.

It is closer to can / may / might, depending on context.

In this sentence, bisa suggests that the staff have the option or authority to do this, or that this may happen.

So it is not only about physical ability. It is more like:

• the staff can ask you to return to the counter
• the staff may ask you to return to the counter

That is often how bisa works in real Indonesian: it can cover ability, possibility, or permitted action depending on context.
