Adik perempuan saya lebih suka kartu debit daripada dompet digital karena dia tidak perlu memindai kode QR setiap kali membayar.

Yes. Adik means younger sibling, and perempuan means female. So adik perempuan saya means my younger sister.

A few useful comparisons:

• adik = younger sibling
• kakak = older sibling
• adik perempuan = younger sister
• adik laki-laki = younger brother

Indonesian often builds family terms this way, by starting with the relationship and then adding gender if needed.

In Indonesian, possession is commonly shown by putting the possessor after the noun.

So:

• adik perempuan saya = my younger sister
• literally, something like younger sister of me

This is very normal Indonesian word order. The same pattern appears in:

• rumah saya = my house
• teman saya = my friend
• kartu debit saya = my debit card

This is the standard pattern for saying that someone prefers one thing over another.

Pattern:

• lebih suka X daripada Y = prefer X to Y

In this sentence:

• lebih suka kartu debit daripada dompet digital = prefers debit cards to digital wallets

Breakdown:

• lebih = more
• suka = like
• daripada = than / rather than

So literally it is close to likes debit cards more than digital wallets.

Because daripada is the normal word used in comparisons like more ... than ....

Examples:

• lebih besar daripada = bigger than
• lebih murah daripada = cheaper than
• lebih suka X daripada Y = prefer X to Y

In casual speech, some speakers may shorten things or use dari in certain contexts, but daripada is the safer and more standard choice for this kind of comparison.

Indonesian does not use articles the way English does. There is no direct equivalent of the or a/an in most everyday sentences.

So:

• kartu debit can mean a debit card, debit cards, or the debit card, depending on context
• dompet digital can mean a digital wallet or digital wallets

The exact meaning is usually understood from context rather than from an article.

Because Indonesian third-person singular pronouns usually do not mark gender.

• dia = he / she
• ia = he / she, but more formal and more common in writing

So in this sentence, dia could grammatically mean either he or she, but the earlier phrase adik perempuan saya tells you it is she.

This is very common in Indonesian: gender is often left unspecified unless it matters.

Tidak perlu means do not need to or doesn’t need to.

So:

• dia tidak perlu memindai kode QR = she doesn’t need to scan a QR code

Breakdown:

• tidak = not
• perlu = necessary / need

A helpful comparison:

• tidak perlu = not necessary, no need
• tidak usah = don’t have to / no need to, often a bit more conversational
• harus = must
• tidak harus = does not have to

In this sentence, tidak perlu fits very naturally.

Because Indonesian often adds the prefix meN- to form an active verb.

Here:

• root: pindai = scan
• active verb: memindai = to scan

This is part of a very common verb system in Indonesian.

A useful detail: when meN- is added to a root beginning with p, the p usually drops.

So:

• pindai → memindai

Other similar patterns:

• pakai → memakai
• pilih → memilih

In everyday speech, people may sometimes use borrowed forms like scan, but memindai is a good standard Indonesian form.

Because Indonesian usually puts the main noun first and the modifier after it.

So:

• kode QR = QR code
• kartu debit = debit card
• dompet digital = digital wallet

This is a very common noun pattern in Indonesian:

• head noun first
• describing word after it

English often does the opposite, so this can take some getting used to.

Setiap kali means every time or whenever.

Breakdown:

• setiap = every / each
• kali = time, in the sense of an occasion

So:

• setiap kali membayar = every time she pays / whenever she pays

You need both words because setiap by itself means every, but it needs a noun:

• setiap hari = every day
• setiap minggu = every week
• setiap kali = every time

Because Indonesian verbs can often appear without an explicit object when the object is understood from context.

So membayar here simply means to pay or to make a payment.

The idea is clear already: she is paying in a shopping or transaction context, so no extra object is necessary.

Compare:

• Saya membayar. = I’m paying.
• Saya membayar tagihan. = I’m paying the bill.
• Saya membayar kopi itu. = I’m paying for that coffee.

All of these are natural depending on context.

Yes, but karena is one of the most common and natural choices.

Some alternatives are:

• karena = because
• sebab = because / cause, a bit more formal or written in some contexts
• soalnya = because / the thing is, more conversational

In this sentence, karena is the most straightforward and neutral option.

Yes. Indonesian is fairly flexible here, just like English.

The original order is:

• main idea first
• reason second

So:

• Adik perempuan saya lebih suka kartu debit daripada dompet digital karena dia tidak perlu memindai kode QR setiap kali membayar.

You could also put the reason first:

• Karena dia tidak perlu memindai kode QR setiap kali membayar, adik perempuan saya lebih suka kartu debit daripada dompet digital.

Both are grammatical. The original version sounds natural and straightforward in everyday use.
