Sebaiknya kita memeriksa dokumen itu sebelumnya agar rapat berjalan lancar.

Sebaiknya means something like it would be best, should, or it’s advisable to.

It is usually softer and more polite than a direct command. In this sentence, Sebaiknya kita memeriksa... means We should check... or It would be best if we checked...

So it gives a recommendation, not a strict order.

Periksa is the base word, meaning check or examine.

When Indonesian adds the prefix meN-, it often creates an active verb. So:

• periksa = check/examine
• memeriksa = to check / checking

Here, memeriksa is the normal active verb form after kita:

• kita memeriksa dokumen itu = we check the document

Using periksa by itself here would sound less standard in careful written Indonesian.

This is because the meN- prefix changes form depending on the first sound of the root word.

With roots beginning with p, the p often disappears and meN- becomes mem-:

• pakai → memakai
• pilih → memilih
• periksa → memeriksa

So memeriksa is the expected form.

This is a very common question.

Indonesian has two words for we:

• kita = we, including the listener
• kami = we, excluding the listener

So Sebaiknya kita memeriksa... suggests that the speaker includes the person they are talking to: you and I / all of us should check the document.

If it said kami, it would mean we (not you) should check it.

Dokumen itu means that document or the document depending on context.

In Indonesian, demonstratives like ini and itu usually come after the noun:

• dokumen ini = this document
• dokumen itu = that document

This is different from English, where this/that comes before the noun.

Also, in real usage, itu can sometimes function a bit like the, especially when the thing is already known from context.

Sebelumnya means beforehand, previously, or earlier.

It comes from:

• sebelum = before
• -nya = a suffix that can make it sound more adverbial or definite in this kind of expression

So in this sentence, sebelumnya means in advance or before that time.

For example:

• Kita harus datang sebelumnya. = We have to come earlier / beforehand.

Not exactly.

• sebelum is usually used with a following clause or noun phrase:

  • sebelum rapat = before the meeting
  • sebelum kita mulai = before we begin

• sebelumnya often stands alone as an adverb:

  • Periksa dulu sebelumnya. = Check it beforehand.

In your sentence, sebelumnya works well because the exact reference point is understood from context: before the meeting or before the discussion proceeds.

Agar means so that or in order that.

In this sentence:

• agar rapat berjalan lancar = so that the meeting goes smoothly

Agar and supaya are very similar, and in many everyday situations they are interchangeable.

• agar often sounds a little more formal or written
• supaya is very common in speech

So this sentence could also be:

• Sebaiknya kita memeriksa dokumen itu sebelumnya supaya rapat berjalan lancar.

That would still sound natural.

Yes, berjalan literally can mean to walk or to move along, but it is also very commonly used more broadly to mean:

• to run
• to proceed
• to take place smoothly
• to function

So rapat berjalan lancar is a very natural expression meaning:

• the meeting goes smoothly
• the meeting runs smoothly

This is similar to English, where we say a meeting runs well even though it is not literally running.

Lancar means smooth, fluent, or without problems/obstacles, depending on context.

In this sentence:

• rapat berjalan lancar = the meeting runs smoothly

You may also see lancar in other contexts:

• Bahasa Indonesianya lancar. = His/Her Indonesian is fluent.
• Lalu lintas lancar. = Traffic is flowing smoothly.
• Pembayaran lancar. = Payments are going smoothly / regularly.

Yes. The sentence breaks down like this:

• Sebaiknya = it would be best / should
• kita = we
• memeriksa = check
• dokumen itu = that document / the document
• sebelumnya = beforehand
• agar = so that
• rapat = meeting
• berjalan lancar = goes smoothly / runs smoothly

So the structure is basically:

Recommendation + subject + action + object + time expression + purpose clause

That is:

Sebaiknya kita memeriksa dokumen itu sebelumnya agar rapat berjalan lancar.

= It would be best for us to check the document beforehand so that the meeting runs smoothly.

In this sentence, sebelumnya comes after dokumen itu, and that sounds natural.

Indonesian word order is often flexible, especially with adverbs. You may also hear:

• Sebaiknya kita sebelumnya memeriksa dokumen itu agar rapat berjalan lancar.

But this version is a little less natural in many contexts.

The original sentence is smoother because sebelumnya comes after the object and clearly modifies the action memeriksa.

So for learners, the original order is a very good model:

• memeriksa dokumen itu sebelumnya

It sounds neutral to slightly formal.

Why?

• sebaiknya sounds polite and somewhat formal
• agar is a bit more formal than supaya
• the sentence is complete and well-structured

It would fit well in:

• workplace communication
• school or academic discussion
• presentations
• written advice

In casual speech, someone might say something slightly simpler, such as:

• Kita cek dokumen itu dulu aja biar rapatnya lancar.

That is more conversational.

Yes, depending on context.

• dokumen = document
• berkas = file/document set, often used in offices or administration
• file = file, especially digital file

So possible alternatives are:

• Sebaiknya kita memeriksa berkas itu sebelumnya...
• Sebaiknya kita memeriksa file itu sebelumnya...

But dokumen is a very solid, general choice and works well in both written and spoken Indonesian.

It is not a rigid idiom in the sense that it cannot change, but it is a very common and natural collocation.

Common combinations include:

• acara berjalan lancar = the event goes smoothly
• rapat berjalan lancar = the meeting goes smoothly
• proses berjalan lancar = the process runs smoothly
• semuanya berjalan lancar = everything went smoothly

So yes, this is a very useful pattern to learn:

• X berjalan lancar = X goes/runs smoothly
