Saya sulit fokus gara-gara notifikasi di ponsel.

Here, gara-gara means because of, due to, or as a result of.

So:

• Saya sulit fokus = I have trouble focusing
• gara-gara notifikasi di ponsel = because of the notifications on the phone

A useful nuance: gara-gara often sounds a bit like the speaker is blaming something, especially for a problem or annoyance. So it fits well here.

Gara-gara is fairly informal / conversational.

In more neutral or formal Indonesian, you might use:

• karena = because
• akibat = as a result of
• disebabkan oleh = caused by

For example:

• Saya sulit fokus karena notifikasi di ponsel.
• Saya sulit fokus akibat notifikasi di ponsel.

The original sentence sounds natural in everyday speech.

Both are possible.

• sulit fokus = hard to focus
• sulit untuk fokus = hard to focus

Indonesian often leaves out untuk when the meaning is already clear. That makes the sentence shorter and more natural in everyday use.

So:

• Saya sulit fokus sounds natural
• Saya sulit untuk fokus is also correct, but a little more explicit

Yes. Susah and sulit can both mean hard / difficult here.

The difference is mainly tone:

• sulit = a bit more standard or neutral
• susah = more casual and everyday

So all of these work:

• Saya sulit fokus
• Saya susah fokus

Both are natural, but susah fokus may sound a little more colloquial.

In this sentence, fokus works like to focus / focused.

Indonesian word classes are often more flexible than English ones. A word like fokus can appear in structures where English would require different forms.

So:

• Saya fokus = I am focused
• Saya sulit fokus = I have trouble focusing

You do not need a separate verb like to be or an infinitive marker like to.

Because Indonesian does not need it here.

In English, we often say:

• I can’t focus well
• It’s hard for me to focus

In Indonesian, Saya sulit fokus already expresses that idea. It means something like:

• I find it hard to focus
• It’s difficult for me to focus

So no extra word like bisa is necessary.

Because Indonesian nouns usually do not change form for singular vs. plural.

So notifikasi can mean:

• notification
• notifications

The context tells you which one is meant.

If you really want to emphasize plurality, you can sometimes use reduplication:

• notifikasi-notifikasi

But in normal speech, that is often unnecessary. In this sentence, notifikasi naturally reads as notifications.

In Indonesian, di is a general preposition that can mean in, at, or on, depending on context.

So:

• di ponsel = on the phone / in the phone

English makes finer distinctions between in and on, but Indonesian often just uses di.

So notifikasi di ponsel is a normal way to say notifications on the phone.

Because Indonesian often leaves out possessives when they are already understood from context.

So:

• di ponsel = on the phone
• di ponsel saya = on my phone

If the speaker is obviously talking about their own phone, saya can be omitted. Adding it makes the meaning more explicit.

So both are possible:

• Saya sulit fokus gara-gara notifikasi di ponsel.
• Saya sulit fokus gara-gara notifikasi di ponsel saya.

The second one is more specific.

Ponsel is correct and common, but in everyday Indonesian many people also say:

• HP
• handphone

Examples:

• notifikasi di ponsel
• notifikasi di HP

Both are natural. Ponsel can sound a bit more standard, while HP is extremely common in casual speech.

Yes, in casual conversation it can be omitted if the context is clear.

For example:

• Sulit fokus gara-gara notifikasi di ponsel.

This can still mean I’m having trouble focusing because of notifications on my phone, especially if it is obvious who is speaking.

But including Saya makes the sentence complete and clear on its own.

Yes, a little.

That feeling comes mainly from gara-gara, which often suggests that something is causing a problem and the speaker is annoyed or affected by it.

So the sentence does not just state a neutral cause. It sounds a bit like:

• I can’t focus because of these phone notifications
• The phone notifications are messing with my focus

That makes it very natural in spoken Indonesian.
