Aku jadi ketagihan martabak.

Aku means I and is more casual, personal, and everyday than saya.

• aku = informal / friendly / intimate
• saya = more formal / polite / neutral in formal situations

So Aku jadi ketagihan martabak sounds natural in casual speech, like talking to friends.
A more formal version would be Saya jadi ketagihan martabak, though the whole sentence still feels fairly conversational.

Here, jadi means something like to become, to end up, or to come to be.

So:

• Aku jadi ketagihan martabak = I became addicted to martabak / I ended up getting hooked on martabak

This is a very common use of jadi in Indonesian. It often marks a change of state:

• Saya jadi takut. = I became scared.
• Dia jadi marah. = He/She became angry.

In other contexts, jadi can also mean so, therefore, or finished/done, so learners often need to judge it from context.

Ketagihan means addicted, hooked, or craving something repeatedly.

It is often used not only for serious addiction, but also in a lighter, everyday way, like:

• ketagihan kopi = hooked on coffee
• ketagihan drama Korea = addicted to Korean dramas
• ketagihan martabak = hooked on martabak

So it can sound quite natural and even playful, depending on context.

Ketagihan comes from the root tagih, but in modern usage ketagihan is best learned as a whole word meaning to become addicted / hooked.

The prefix-suffix pattern ke- ... -an often forms adjectives or states in Indonesian. In this case, it gives the idea of being in a state of craving or addiction.

For many learners, the most practical approach is:

• memorize ketagihan as a set expression
• learn the pattern through examples rather than trying to force a direct English-style breakdown

Useful examples:

• Dia ketagihan game. = He/She is addicted to games.
• Saya ketagihan makanan pedas. = I’m hooked on spicy food.

In Indonesian, you often do not need a separate word corresponding to English to after words like ketagihan.

So:

• ketagihan martabak literally looks like addicted martabak
• but naturally means addicted to martabak

This is normal Indonesian grammar. Many Indonesian verbs and adjectives connect directly to the thing they relate to, without a preposition that English would require.

Not exactly in the same way as a direct object after a typical verb like eat.

In Aku jadi ketagihan martabak, martabak is the thing the speaker is addicted to. It follows ketagihan directly, but it is better to think of it as the complement of ketagihan, not as a classic direct object.

That distinction is useful because ketagihan behaves more like a state or condition than a straightforward action verb.

Yes. Aku ketagihan martabak is completely natural.

The difference is:

• Aku ketagihan martabak = I’m addicted to martabak / I’m hooked on martabak
• Aku jadi ketagihan martabak = I became addicted to martabak / I ended up getting hooked on martabak

So jadi highlights the change into that state.

Usually, yes. Adding jadi suggests that the speaker was not like this before, but then things changed.

It does not always have to mean very recently, but it does imply a transition:

• before: not addicted
• now: hooked on martabak

If you want to make the timeline clearer, Indonesian can add time expressions:

• Akhir-akhir ini aku jadi ketagihan martabak. = Lately I’ve become addicted to martabak.
• Sejak pindah ke Bandung, aku jadi ketagihan martabak. = Since moving to Bandung, I’ve become hooked on martabak.

No. In everyday Indonesian, ketagihan is very often used loosely and casually.

It can refer to:

• food
• drinks
• TV shows
• games
• hobbies

So Aku jadi ketagihan martabak does not necessarily sound medically serious. It often just means I can’t stop wanting martabak or I really got into martabak.

Of course, in some contexts it can describe a more serious addiction, but with food like martabak, it is usually lighthearted.

Martabak is a noun: the name of a popular dish in Indonesia.

There are two well-known types:

• martabak manis = sweet, thick pancake-like dessert with fillings/toppings
• martabak telur = savory stuffed egg-filled fried dish

So the sentence could mean the speaker got hooked on either kind, depending on context.

Yes, it sounds natural and conversational.

A native speaker could easily say:

• Aku jadi ketagihan martabak.

Some close alternatives are:

• Aku ketagihan martabak.
• Aku jadi suka banget sama martabak. = I ended up really loving martabak.
• Aku sekarang ketagihan martabak. = Now I’m hooked on martabak.

The original sentence is simple, idiomatic, and very natural in casual speech.

Yes, jadi can also mean so, then, or therefore in other sentences.

For example:

• Jadi, kita pergi sekarang? = So, are we leaving now?

But in Aku jadi ketagihan martabak, that meaning does not fit well. Here jadi is clearly part of the idea become/get hooked.

A good way to tell is to look at what follows:

• jadi + adjective/state often means become
• sentence-initial Jadi, ... often means so / then

So in this sentence, jadi ketagihan is naturally read as became addicted.
