Kalau semua urusan sudah beres, pamitlah dulu dengan sopan sebelum keluar dari ruangan.

Kalau means if here, though in many contexts it can also feel like when if the condition is expected.

• Kalau semua urusan sudah beres = If all matters are settled
• Jika would also be correct, but it sounds a bit more formal or written.

So:

• Kalau = common, conversational, natural
• Jika = more formal, often used in writing or official speech

In this sentence, kalau sounds very natural.

Urusan means something like matters, business, affairs, or things that need to be taken care of.

It does not always mean business in the commercial sense. It can refer to any task, responsibility, or matter at hand.

So semua urusan means:

• all matters
• everything that needs to be dealt with
• all your business here

It is a very common word in Indonesian.

They do different jobs:

• sudah = already
• beres = finished, settled, in order, taken care of

So sudah beres means already finished or already settled.

You need beres because sudah by itself does not tell you what state has been reached.
Compare:

• Semua urusan sudah beres = All matters are already settled
• Semua urusan sudah = incomplete and unnatural on its own

So beres is the main predicate, and sudah marks completion.

Not exactly.

Pamit means to take leave politely, especially before going away from someone, a place, a host, an elder, or a superior. It has a cultural nuance of asking permission or respectfully announcing that you are leaving.

So it is related to saying goodbye, but it is more specific than that.

For example:

• Saya pamit dulu = I will take my leave now / Excuse me, I should go now

This sounds polite and respectful. It is especially common in social situations, family settings, and formal situations.

The particle -lah often softens, emphasizes, or makes an instruction sound smoother and more natural.

Here, pamitlah is an imperative, but it does not sound as blunt as a plain command in English might.

Compare:

• pamit = take leave / say goodbye
• pamitlah = do take leave / please take leave

In many contexts, -lah can make advice or instructions sound more polished, literary, or politely directive.

So pamitlah dulu feels like:

• please take your leave first
• do excuse yourself first

No. In this sentence, dulu does not mean formerly or in the past.

Here, dulu means something like:

• first
• beforehand
• before doing the next thing
• for now

So pamitlah dulu ... sebelum keluar means:

• first excuse yourself politely before leaving
• take leave first before going out

This is a very common use of dulu in everyday Indonesian.

For example:

• Makan dulu = Eat first
• Duduk dulu = Sit down first
• Saya pamit dulu = I’ll excuse myself first / I should get going now

Sopan is basically an adjective meaning polite.

To express politely in a straightforward way, Indonesian often uses:

• dengan + adjective

So:

• dengan sopan = politely / in a polite manner

This is very natural.

Sometimes Indonesian can omit dengan in certain expressions, but dengan sopan is clear and standard. It explicitly tells you how to do the action pamit.

Because the subject is understood from the main clause.

Indonesian often omits subjects when they are clear from context. Here, the person being told to pamitlah is also the one who will keluar.

So sebelum keluar dari ruangan literally looks like:

• before leaving the room

with no explicit you, but the meaning is clearly:

• before you leave the room

This kind of subject omission is very common and natural in Indonesian.

Because keluar usually works with dari when you say the place someone exits from.

• keluar dari ruangan = go out of the room
• keluar dari rumah = leave the house
• keluar dari kantor = leave the office

The preposition dari marks the source or starting point.

In casual speech, some people may shorten expressions, but keluar dari ruangan is the standard and clear form.

Both relate to room/space, but there is a slight nuance.

• ruang = room, space
• ruangan = a room/an enclosed room area

In many contexts, they overlap. But ruangan often feels a bit more concrete as an actual room and can sound slightly more formal or descriptive.

So keluar dari ruangan sounds very natural for leave the room.

It is basically an instruction or polite directive.

The structure is:

• Kalau ... , pamitlah ... sebelum ...

That means:

• If/when X is finished, do Y before Z

Because of pamitlah, it has an imperative feel, but it is not harsh. It sounds like polite advice, etiquette instruction, or a rule of proper behavior.

So the tone is something like:

• Once everything is settled, please excuse yourself politely before leaving the room.

It is fairly neutral to polite, and it leans a bit formal because of words like:

• pamit
• -lah
• ruangan
• dengan sopan

It sounds appropriate for:

• etiquette advice
• instructions
• school materials
• polite spoken Indonesian

In very casual conversation, people might say something simpler, such as:

• Kalau urusannya sudah beres, pamit dulu sebelum keluar.

But the original sentence is perfectly natural and polite.
