Saya sudah terbiasa belajar tanpa musik di perpustakaan.

Here, sudah adds the idea of already or by now.

In Saya sudah terbiasa belajar tanpa musik di perpustakaan, it suggests that the speaker is now accustomed to doing this. A natural English idea is:

• I’m already used to studying without music in the library
• I have gotten used to studying without music in the library

So sudah is not just about past time. It often marks that a state has been reached.

This is a very common question.

• biasa = usual, normal, ordinary; sometimes also used to
• terbiasa = accustomed, habituated, used to something through experience

In this sentence, terbiasa is better because it emphasizes that the speaker has become accustomed to that habit.

Compare:

• Saya biasa belajar di perpustakaan
  = I usually study at the library

• Saya terbiasa belajar di perpustakaan
  = I am used to studying at the library

So biasa often talks about what is usual, while terbiasa more clearly expresses being accustomed to something.

In Indonesian, after terbiasa, it is very common to put a verb directly:

• terbiasa bangun pagi
• terbiasa bekerja sendiri
• terbiasa belajar tanpa musik

This is natural and standard.

You may sometimes see terbiasa untuk in certain contexts, but it is not the most natural choice here. For everyday Indonesian, terbiasa + verb is usually the best pattern.

Another common pattern is:

• terbiasa dengan + noun

For example:

• Saya sudah terbiasa dengan suasana perpustakaan
  = I’m already used to the library atmosphere

So the two useful patterns are:

• terbiasa + verb
• terbiasa dengan + noun

Belajar means to study, and tanpa musik means without music.

So belajar tanpa musik literally means:

• study without music

In natural English, this often implies:

• studying with no music playing
• studying without listening to music

Indonesian does not need to say listening to here. Tanpa musik is enough.

If you wanted to be more explicit, you could say:

• belajar tanpa mendengarkan musik

But that is longer and less natural for this sentence.

Because Indonesian grammar works differently.

In English, we say:

• used to studying

But Indonesian does not need a separate word equivalent to that to in this structure. It simply uses:

• terbiasa belajar

So you should not try to translate word-for-word from English. Think of terbiasa as a unit that can be followed directly by an action.

Di perpustakaan means in the library or at the library. It is a place phrase, and in Indonesian, place information often comes near the end of the sentence.

So this order is very natural:

• Saya sudah terbiasa belajar tanpa musik di perpustakaan

But Indonesian word order is fairly flexible. You could also say:

• Saya sudah terbiasa belajar di perpustakaan tanpa musik

That is also understandable and natural.

The difference is mostly about focus:

• tanpa musik di perpustakaan slightly groups the idea as studying in the library, and doing so without music
• di perpustakaan tanpa musik may sound like the location comes first, then the condition

In many cases, both are fine.

It can correspond to either in the library or at the library in English.

Indonesian di is a general preposition for location. It does not force the same distinction English sometimes makes between in and at.

So:

• di perpustakaan = in the library / at the library

The best English translation depends on context and style, but the Indonesian is the same.

Sometimes yes, if the context is already clear.

Indonesian often drops subjects in conversation when they are understood. So in the right situation, someone might simply say:

• Sudah terbiasa belajar tanpa musik di perpustakaan.

This could still mean I’m already used to studying without music in the library.

However, including Saya makes the sentence clearer and more complete, especially for learners and in neutral written Indonesian.

There are two very useful possibilities:

• Saya belum terbiasa belajar tanpa musik di perpustakaan.
  = I’m not used to studying without music in the library yet.

• Saya tidak terbiasa belajar tanpa musik di perpustakaan.
  = I’m not used to studying without music in the library.

The difference is important:

• belum = not yet, suggesting the state may change
• tidak = plain negation, with no yet idea

So if you want to say someone has not adapted so far, belum terbiasa is often the most natural choice.

Not in the usual passive sense.

Learners often notice ter- and wonder if it is passive. But ter- has several uses in Indonesian. In terbiasa, it does not mean a normal passive like is done or was done.

Instead, terbiasa is best learned as a fixed adjective-like form meaning:

• accustomed
• used to

So although it contains ter-, you should not analyze it the same way as a typical passive verb.

Yes, you could, and many Indonesians would understand it.

But the nuance is slightly different:

• sudah biasa can mean already used to or already accustomed, especially in speech
• sudah terbiasa more clearly emphasizes being habituated or accustomed

So both are possible, but sudah terbiasa is often the clearer and more precise choice for used to doing something.

Because Indonesian usually does not use articles like a, an, or the, and it does not require plural marking in the same way English does.

So:

• musik can mean music
• perpustakaan can mean library or the library, depending on context

The meaning is usually clear from the situation.

That is why tanpa musik di perpustakaan sounds complete in Indonesian even though English would normally need words like the.

A good way to process it is in chunks:

• Saya = I
• sudah = already / by now
• terbiasa = accustomed / used to
• belajar tanpa musik = studying without music
• di perpustakaan = in/at the library

So instead of translating word by word, try to understand it as:

• I’m already used to studying without music in the library

That chunk-based approach will help you sound more natural in Indonesian.
