Saya memeriksa pemesanan taksi di aplikasi sebelum berangkat ke bandara.

Pemesanan is a noun meaning booking, reservation, or the act/result of ordering.

It comes from the root pesan (to order / to book) with the circumfix pe- -an, which often turns a verb into a noun.

• pesan taksi = to book a taxi
• pemesanan taksi = taxi booking / the taxi reservation

So in this sentence, memeriksa pemesanan taksi means to check the taxi booking, not to book a taxi.

Memeriksa means to check, to inspect, or to examine.

In this sentence, it most naturally means to check or review something:

• Saya memeriksa pemesanan taksi = I checked my taxi booking

The root is periksa (check / inspect / examine), and meN- changes it into an active verb:

• periksa → memeriksa

Here di is a preposition meaning in, on, or at, depending on natural English translation.

So di aplikasi literally means in the app, but in natural English it may also be understood as on the app.

Important point:

• di as a preposition is written separately: di aplikasi
• di- as a passive prefix is written together with the verb: for example diperiksa

So here, di aplikasi is definitely a location phrase, not a passive verb.

In Indonesian, once the subject is already clear, it is often omitted in later parts of the sentence.

So in:

• Saya memeriksa pemesanan taksi di aplikasi sebelum berangkat ke bandara

the understood subject of berangkat is still saya.

Literally, it is like:

• I checked the taxi booking in the app before leaving for the airport

Indonesian often does this when the subject stays the same and repeating it would sound unnecessary.

Berangkat means to leave, to depart, or to set off.

The root angkat by itself has meanings related to lift, raise, or carry up, but berangkat is a fixed and very common verb meaning to depart.

Examples:

• Saya berangkat jam 6 = I leave at 6
• Mereka berangkat ke Jakarta = They departed for Jakarta

So learners should usually treat berangkat as its own common vocabulary item meaning leave/depart.

Because ke shows movement toward a destination, while di shows location.

• ke bandara = to the airport
• di bandara = at the airport

Since berangkat involves going somewhere, ke is the correct choice:

• berangkat ke bandara = leave for the airport / go to the airport

It can naturally be understood as either, depending on context.

Berangkat ke bandara often means:

• leave for the airport
• go to the airport
• depart for the airport

In this sentence, the idea is that the speaker checked the taxi booking first, and after that went to the airport.

So before leaving for the airport is probably the most precise translation, but before going to the airport is also fine in many contexts.

Yes. Taksi is the standard Indonesian word for taxi.

It is a loanword adapted to Indonesian spelling:

• English taxi
• Indonesian taksi

In everyday Indonesian, people may also mention specific ride-hailing services, but taksi is the normal general word.

In this sentence, di aplikasi most naturally describes where the checking happened: in/on the app.

So the structure is understood as:

• Saya memeriksa [pemesanan taksi] [di aplikasi]
• I checked [the taxi booking] [in the app]

In real usage, Indonesian prepositional phrases like di aplikasi can sometimes feel slightly flexible, but here the most natural interpretation is that the speaker checked the booking using the app.

If you wanted to make that extra clear, Indonesian could also say something like:

• Saya memeriksa pemesanan taksi lewat aplikasi
• I checked the taxi booking through the app

Saya is the neutral and polite word for I. It works in most situations, especially:

• standard written Indonesian
• formal speech
• neutral everyday communication

Aku is also common, but it is more informal and personal.

So:

• Saya memeriksa... sounds standard and neutral
• Aku memeriksa... sounds more casual

A textbook sentence will very often use saya.

Yes, Indonesian verbs do not automatically show tense the way English verbs do.

Saya memeriksa pemesanan taksi... could be interpreted as:

• I check
• I checked
• I was checking

The time is usually understood from context. In this sentence, because of sebelum berangkat ke bandara (before leaving for the airport), English will usually translate it as a past action:

• I checked the taxi booking in the app before leaving for the airport

So the tense comes from context, not from a verb ending.

This is a very common Indonesian pattern where one noun modifies another.

• pemesanan = booking
• taksi = taxi

So:

• pemesanan taksi = taxi booking

The second noun often functions like of or like an English noun modifier.

Other similar examples:

• tiket pesawat = plane ticket
• jadwal penerbangan = flight schedule
• supir taksi = taxi driver

So pemesanan taksi is completely normal Indonesian noun phrase structure.

Yes, in everyday Indonesian, many speakers would naturally say cek.

For example:

• Saya cek pemesanan taksi di aplikasi sebelum berangkat ke bandara.

That sounds more casual and conversational.

Difference:

• memeriksa = more standard, formal, or careful
• cek = common, informal, everyday speech

Both are understandable, but memeriksa is a more textbook-style choice.

Yes, it is natural and correct. It sounds like standard Indonesian.

It is slightly on the neutral-to-formal side because of words like saya and memeriksa, but it is absolutely normal.

A more casual version might be:

• Aku cek pesanan taksi di aplikasi sebelum berangkat ke bandara.

That version is more conversational, while the original is cleaner and more standard.
