Saya sudah membuat reservasi hotel untuk akhir pekan, tetapi saya masih menunggu konfirmasi lewat email.

In Indonesian, verbs do not change form for tense the way they do in English. Instead, words like sudah help show aspect or time.

• saya = I
• membuat = make / create / do
• sudah = already

So saya sudah membuat reservasi hotel literally means something like I already made a hotel reservation, which naturally corresponds to I have made a hotel reservation in English.

Indonesian often relies on context plus words like:

• sudah = already / has done
• sedang = in the middle of doing
• akan = will / going to
• masih = still

Sudah means already, and in many contexts it shows that an action has been completed.

In this sentence:

• Saya sudah membuat reservasi hotel = I have already made a hotel reservation

It tells you the reservation has been done. Without sudah, saya membuat reservasi hotel could sound more neutral and might depend more on context.

A useful contrast:

• Saya sudah makan = I have already eaten
• Saya belum makan = I have not eaten yet

So sudah is very common when talking about completed actions.

Yes. Membuat reservasi is understandable and natural, especially in formal or semi-formal Indonesian.

• membuat = to make
• reservasi = reservation

So it works very much like English make a reservation.

That said, Indonesian also commonly uses:

• memesan hotel = to book a hotel
• melakukan reservasi = to make/carry out a reservation
• pemesanan hotel = hotel booking

Depending on context, some speakers may prefer saya sudah memesan hotel or saya sudah melakukan reservasi hotel, but membuat reservasi hotel is still perfectly understandable.

You can use both, but they are not identical in feel.

• reservasi = reservation
• pemesanan = booking / ordering

For hotels, restaurants, flights, and tickets:

• reservasi sounds a bit more formal or service-related
• pemesanan is also very common and often sounds slightly more general

Examples:

• Saya sudah membuat reservasi hotel.
• Saya sudah melakukan pemesanan hotel.
• Saya sudah memesan kamar hotel.

All of these can work, but reservasi is especially natural when you want to emphasize the act of reserving.

Indonesian does not have articles like a, an, and the in the same way English does.

So:

• reservasi hotel can mean a hotel reservation or the hotel reservation, depending on context.

Indonesian usually leaves that information implicit unless it really needs to be clarified.

For example:

• Saya membeli buku = I bought a book / I bought the book
• Dia melihat mobil = He/she saw a car / the car

Context tells you which one is meant.

Here untuk akhir pekan means for the weekend.

• untuk = for
• akhir pekan = weekend

So it indicates the reservation is intended for that time period.

Examples:

• Saya memesan kamar untuk akhir pekan. = I booked a room for the weekend.
• Kami menyiapkan acara untuk hari Minggu. = We prepared an event for Sunday.

If you wanted to say something more like on the weekend, Indonesian might use other phrasing depending on context, but in this sentence untuk is best understood as for.

Yes, akhir pekan is a standard and very common way to say weekend.

• akhir = end
• pekan = week

Literally, it means the end of the week.

You may also hear:

• akhir minggu

Both are understood, but akhir pekan is very common in standard Indonesian.

Examples:

• Apa rencanamu akhir pekan ini? = What are your plans this weekend?
• Kami akan pergi ke Bandung pada akhir pekan. = We will go to Bandung on the weekend.

Tetapi means but.

In this sentence, it connects two ideas:

1. the reservation has already been made
2. the speaker is still waiting for confirmation

So:

• ..., tetapi saya masih menunggu ... = ..., but I am still waiting ...

Yes, you can also use tapi. The difference is mainly register:

• tetapi = more formal
• tapi = more casual, very common in speech

Examples:

• Saya mau pergi, tetapi saya sibuk.
• Saya mau pergi, tapi saya sibuk.

Both mean I want to go, but I’m busy.

Masih means still.

• menunggu = to wait / to be waiting
• masih menunggu = still waiting

This tells us the waiting is continuing and has not ended yet.

So:

• saya masih menunggu konfirmasi = I am still waiting for confirmation

Compare:

• Saya menunggu konfirmasi. = I am waiting for confirmation.
• Saya masih menunggu konfirmasi. = I am still waiting for confirmation.

The second sentence emphasizes that the confirmation has not arrived yet.

In Indonesian, menunggu can directly take its object without a separate word for for.

So:

• menunggu konfirmasi = wait for confirmation
• menunggu bus = wait for the bus
• menunggu teman saya = wait for my friend

This is normal Indonesian structure.

English uses wait for, but Indonesian simply uses menunggu + object.

Yes, lewat email means by email, through email, or via email.

• lewat = through / via / by way of
• email = email

So:

• konfirmasi lewat email = confirmation via email

You could also hear:

• melalui email = through/via email

The difference:

• lewat email = common, natural, slightly less formal
• melalui email = a bit more formal

Both are correct.

It could. Both are correct.

• lewat email sounds natural and everyday
• melalui email sounds a little more formal or polished

So these are both possible:

• Saya masih menunggu konfirmasi lewat email.
• Saya masih menunggu konfirmasi melalui email.

The meaning is basically the same.

Yes, in practice konfirmasi is often used as a noun, and it can also appear in verbal expressions when combined with prefixes.

In your sentence, konfirmasi is a noun:

• menunggu konfirmasi = waiting for confirmation

As a verb-related form, you may see:

• mengonfirmasi = to confirm
• dikonfirmasi = to be confirmed
• mengkonfirmasi = also seen in usage, though mengonfirmasi is generally preferred in more standard writing

Examples:

• Saya menunggu konfirmasi dari hotel. = I’m waiting for confirmation from the hotel.
• Pihak hotel akan mengonfirmasi reservasi Anda. = The hotel will confirm your reservation.

Yes, but the tone changes.

• saya = neutral, polite, standard
• aku = more informal and personal

So:

• Saya sudah membuat reservasi hotel... sounds neutral and appropriate in many situations.
• Aku sudah membuat reservasi hotel... sounds more casual, like everyday conversation with friends or family.

Because the sentence includes words like tetapi and has a fairly standard tone, saya fits very well.

Yes, it is natural and understandable. A native speaker would understand it immediately.

That said, there are a few very natural alternatives depending on style:

• Saya sudah memesan hotel untuk akhir pekan, tetapi saya masih menunggu konfirmasi lewat email.
• Saya sudah melakukan reservasi hotel untuk akhir pekan, tetapi saya masih menunggu konfirmasi lewat email.
• Saya sudah booking hotel untuk akhir pekan, tetapi saya masih menunggu konfirmasi lewat email.
  This one is more colloquial because booking is borrowed from English and is very common in speech.

Your original sentence is perfectly good, especially in standard written Indonesian.

Yes, the word order is very typical of Indonesian and is fairly straightforward.

The sentence is:

• Saya = subject
• sudah membuat reservasi hotel untuk akhir pekan = predicate + object + purpose/time phrase
• tetapi = connector
• saya masih menunggu konfirmasi lewat email = second clause

A rough structure is:

Subject + aspect marker + verb + object + additional information

Then:

tetapi + subject + aspect marker + verb + object + method/channel

This is one reason Indonesian often feels quite direct to English speakers: the sentence order is often easy to follow.

You could make it more conversational like this:

• Aku sudah booking hotel buat akhir pekan, tapi aku masih nunggu konfirmasi lewat email.

Changes:

• saya → aku
• untuk → buat in casual speech
• tetapi → tapi
• menunggu → nunggu in casual speech
• membuat reservasi hotel → booking hotel, which is very common informally

This version is less formal but very natural in everyday conversation.
