Setelah rapat, Mbak resepsionis memasukkan surat ke amplop dan menaruhnya dekat printer.

Setelah rapat is a time expression, and Indonesian very often puts time expressions at the beginning of a sentence to set the scene.

So the structure is basically:

After the meeting, + main action

This is very natural in Indonesian. It does not sound unusual or marked.

Mbak is a respectful way to refer to or address a woman, especially a younger adult woman or someone around your age. It is very common in Indonesian, especially in Java and in urban speech.

In Mbak resepsionis, it makes the phrase sound polite and natural, something like the receptionist lady or the female receptionist in context.

It is also worth noting that Indonesian has no direct equivalent of a or the, so context tells you whether it means a receptionist or the receptionist.

A good learner-friendly pronunciation is em-bak.

A few notes:

• The a is like the a in father
• The final k is often very light or unreleased in many accents
• In fast speech, native speakers may pronounce it very smoothly

So if you say something close to em-bak, you will usually be understood.

Because masuk and memasukkan do different jobs.

• masuk = to enter / to go in
• memasukkan = to put something in / to insert

So:

• Surat masuk ke amplop would mean something like the letter goes into the envelope
• Mbak resepsionis memasukkan surat ke amplop means the receptionist puts the letter into the envelope

The verb memasukkan is transitive, so it takes an object: surat.

Ke shows movement toward a destination.

So memasukkan surat ke amplop means the letter is being moved into the envelope.

Compare:

• ke amplop = into the envelope, toward the envelope as a destination
• di amplop = at/on the envelope, which would not fit this meaning
• dalam amplop = inside the envelope

With a verb of movement like memasukkan, ke is the most natural choice.

Menaruhnya = menaruh + -nya

• menaruh = to put / to place
• -nya = it

So menaruhnya means to put it or to place it.

This kind of attached pronoun is very common in Indonesian.

It refers to it, but the exact referent can be a little context-dependent.

In this sentence, it most likely refers to the thing just handled in the previous action. Depending on context, listeners may understand it as:

• the letter
• or possibly the envelope with the letter in it

If a speaker wants to be completely clear, they can repeat the noun instead of using -nya.

For example:

• ... dan menaruh amplop itu dekat printer
• ... dan menaruh surat itu dekat printer

Because the subject is still the same: Mbak resepsionis.

Indonesian often joins two verbs with dan when the same subject does both actions:

Mbak resepsionis memasukkan ... dan menaruhnya ...

This is completely normal and very natural. Repeating the subject would usually sound unnecessary unless you want extra emphasis.

Both are possible.

• dekat printer = near the printer
• di dekat printer = near the printer

In everyday Indonesian, speakers often use dekat directly after verbs like taruh or menaruh. Adding di makes the location phrase a little more explicit, but the meaning is basically the same here.

So both of these are natural:

• menaruhnya dekat printer
• menaruhnya di dekat printer

Yes. Printer is very commonly used in Indonesian as a loanword from English.

Indonesian uses many borrowed words for office and technology items, so this sounds perfectly normal. A more purely Indonesian-style word might exist in theory, but in real everyday language, printer is what people usually say.

The same is true for resepsionis, which is also a borrowed word.

Yes, absolutely.

Both can mean to put or to place.

A rough difference is:

• menaruh = very common, everyday, conversational
• meletakkan = slightly more formal or neutral

So menaruhnya dekat printer and meletakkannya dekat printer are both correct. The version with menaruh sounds a bit more casual and natural in daily speech.
