Semalam saya begadang menyelesaikan laporan, jadi pagi ini saya keburu lelah sebelum rapat dimulai.

Here, semalam means last night.

It is very close in meaning to tadi malam, which also means last night. In many everyday situations, they can be used interchangeably.

A useful thing to know is that semalam can also mean for one night in other contexts, so the meaning depends on context.

• Semalam saya begadang = Last night I stayed up late
• Saya menginap semalam = I stayed overnight / for one night

So in this sentence, the time expression clearly makes semalam mean last night.

Begadang means to stay up late, usually late into the night and often instead of sleeping.

It often carries the idea that you are awake much later than normal, especially because you are doing something:

• begadang belajar = staying up late studying
• begadang nonton bola = staying up late watching football
• begadang kerja = staying up late working

In your sentence, begadang implies the speaker did not get enough rest because they stayed up late finishing the report.

This is a very common Indonesian pattern. After one verb, another verb can follow to show purpose or what you were doing.

So:

• begadang menyelesaikan laporan
  = stay up late finishing the report = stay up late to finish the report

English often uses to or in order to, but Indonesian often just puts the verbs together naturally.

You could say:

• Semalam saya begadang untuk menyelesaikan laporan

and that is grammatical, but it sounds a bit more explicit. The original version is more natural and efficient.

Because menyelesaikan means to finish something / to complete something, while selesai usually means finished / done or to be finished.

Compare:

• Saya menyelesaikan laporan = I completed the report
• Laporannya selesai = The report is finished

So menyelesaikan is the active verb used when there is an object being completed.

A quick breakdown:

• selesai = finished, done
• menyelesaikan = to finish/complete something

The suffix -kan often helps form a transitive verb, meaning the action is done to an object.

Jadi here means so, therefore, or as a result.

It connects the first clause and the second clause:

• Semalam saya begadang menyelesaikan laporan
  = Last night I stayed up late finishing the report
• jadi pagi ini saya keburu lelah
  = so this morning I ended up tired early / was already tired

So jadi shows a cause-and-result relationship.

In casual and neutral Indonesian, jadi is extremely common for this.

Keburu is a very useful word, and it can be tricky at first.

In this sentence, keburu means something like:

• already
• too soon
• before expected
• by the time... already

So saya keburu lelah sebelum rapat dimulai means the speaker became tired sooner than they wanted, specifically before the meeting even started.

The nuance is important: it is not just I was tired. It is more like:

• I got tired too early
• I was already tired before the meeting started

This gives the sentence a feeling of inconvenience or bad timing.

Not always, but it often suggests that something happened earlier than desired, before another event, or with a sense of unfortunate timing.

For example:

• Saya keburu lapar sebelum makan siang
  = I got hungry before lunch
• Dia keburu pergi
  = He left already / He left before I could do something
• Kami keburu terlambat
  = We ended up already too late

So it often carries a sense of too soon, already by that point, or before something else could happen.

In your sentence, the speaker is tired before the meeting starts, which is clearly not ideal.

Pagi ini means this morning.

Indonesian time expressions are quite flexible, but they are very often placed near the beginning of the clause:

• jadi pagi ini saya keburu lelah
• jadi saya pagi ini keburu lelah

Both are possible, but the first one sounds more natural and straightforward.

Putting time expressions early helps set the scene quickly. Indonesian does this very often with words like:

• kemarin
• tadi
• besok
• sekarang
• pagi ini

So pagi ini is simply the natural placement for this morning.

Dimulai is the passive form of memulai, so it literally means to be started.

• sebelum rapat dimulai = before the meeting is started / before the meeting starts

In natural English, we usually just say before the meeting started, but Indonesian often uses the passive here because the meeting is viewed as an event that gets started.

You may also hear:

• sebelum rapat mulai

This is also common, especially in casual speech. It is shorter and more conversational.

So:

• sebelum rapat dimulai = slightly more formal or standard
• sebelum rapat mulai = very common and natural in speech

That is very normal in Indonesian.

Passive forms are often used when the doer is unknown, unimportant, or obvious from context. With events like meetings, classes, shows, and programs, Indonesian commonly focuses on the event itself rather than on who starts it.

For example:

• Acara dimulai pukul tujuh = The event starts at seven
• Pelajaran dimulai sekarang = The lesson starts now
• Rapat dimulai setelah makan siang = The meeting starts after lunch

Even though these are passive in form, they often translate into natural English as active-looking sentences.

Not quite.

• Saya sudah lelah = I am already tired
• Saya keburu lelah = I got tired too soon / I was already tired before expected

So sudah mainly marks that something has already happened or is already true.

Keburu adds the idea that it happened before another point or earlier than ideal.

In your sentence, keburu works especially well because it is followed by sebelum rapat dimulai. That creates a clear contrast:

• I became tired
• before the meeting even started

That is exactly the kind of situation where keburu sounds natural.

Yes. A more casual spoken version might be:

• Tadi malam saya begadang nyelesaiin laporan, jadi pagi ini saya udah capek sebelum rapat mulai.

Changes:

• semalam → tadi malam
• menyelesaikan → nyelesaiin (colloquial spoken form)
• lelah → capek (more conversational than lelah)
• dimulai → mulai
• sudah may appear as udah

The original sentence sounds natural and fairly standard. A casual version would simply use more spoken vocabulary and shorter forms.

It is mostly neutral to semi-formal.

Why?

• saya is neutral/polite
• menyelesaikan is standard and not slangy
• lelah sounds a bit more formal than capek
• dimulai is standard and slightly more formal than mulai

So this sentence would fit well in normal writing, careful speech, or polite conversation. It does not sound stiff, but it is definitely more polished than everyday slang.

You can try, but it will sound unnatural in English.

A very literal breakdown would be:

• Semalam = last night
• saya = I
• begadang = stayed up late
• menyelesaikan laporan = finishing/completing the report
• jadi = so
• pagi ini = this morning
• saya = I
• keburu lelah = became tired too soon / was already tired
• sebelum rapat dimulai = before the meeting was started / before the meeting started

The best way to understand it is as a natural Indonesian sentence, not as a strict word-for-word English map. The key things to notice are:

• verb chaining: begadang menyelesaikan
• result link: jadi
• nuance word: keburu
• passive event expression: rapat dimulai

Those are the parts that matter most for learning how Indonesian works.
