Saya belum sarapan, jadi perut saya kosong dan badan saya terasa lemas.

Belum means not yet, while tidak usually means not in a more general sense.

So:

• Saya belum sarapan = I haven’t had breakfast yet
• Saya tidak sarapan = I don’t eat breakfast / I am not having breakfast

In this sentence, belum is the natural choice because it refers to something that has not happened up to now, but still could.

It can mean both, depending on context.

• As a noun: Sarapan saya roti. = My breakfast is bread.
• As a verb: Saya sarapan jam tujuh. = I have breakfast at seven.

In Saya belum sarapan, it functions like a verb: I haven’t had breakfast yet.

This is very common in Indonesian: one word can often work as different parts of speech without changing form.

Indonesian often does not use a verb like to be in places where English does.

English: I am hungry, I am tired, I am a student
Indonesian: Saya lapar, Saya lelah, Saya mahasiswa

So in Saya belum sarapan, there is no need for am. Indonesian grammar usually works fine without it.

Here, jadi means so, therefore, or as a result.

It connects the cause and the result:

• Saya belum sarapan = cause
• jadi perut saya kosong dan badan saya terasa lemas = result

So jadi is a very natural way to say so in everyday Indonesian.

Yes, literally it means my stomach is empty, and that is a normal, natural expression in Indonesian.

• perut = stomach / belly
• kosong = empty

It can describe the feeling of not having eaten. It sounds natural in Indonesian, even if English speakers might more often say I have an empty stomach, my stomach is empty, or just I’m hungry.

In Indonesian, possession usually works as:

noun + possessor

So:

• perut saya = my stomach
• badan saya = my body
• buku saya = my book

This is different from English, where the possessor usually comes first.

A helpful pattern is:

• rumah saya = my house
• nama Anda = your name
• teman mereka = their friend

It is repeated because Indonesian often keeps possessors clear, especially when there are multiple body parts or ideas in one sentence:

• perut saya
• badan saya

This makes the sentence clear and natural.

Could it be shortened? Sometimes yes, especially in casual speech, if the meaning is obvious. But in standard, careful Indonesian, repeating saya is perfectly normal.

For example, a more casual version might be:

• Saya belum sarapan, jadi perut kosong dan badan terasa lemas.

This is understandable, but the original version is clearer and more complete.

They refer to different parts of the body:

• perut = stomach / belly / abdomen
• badan = body

So the sentence is saying:

• the stomach is empty
• the body feels weak

That is why both words are used. They are not interchangeable here.

Terasa means something like feels, can be felt, or feels like.

So:

• badan saya terasa lemas = my body feels weak

It comes from rasa related to feeling/sensation.

This structure is common when describing sensations:

• Tanganku terasa sakit. = My hand feels painful.
• Udara terasa dingin. = The air feels cold.

It gives a slightly more descriptive, sensory feeling than just saying is weak.

Both are possible, but they focus on the feeling a little differently.

• Saya merasa lemas = I feel weak
• Badan saya terasa lemas = My body feels weak

The first focuses on you as the experiencer.
The second focuses on the physical sensation in the body.

So badan saya terasa lemas sounds especially physical and bodily, which fits well after saying you have not eaten breakfast.

This is a very common question.

• lemas = weak, limp, lacking energy, physically drained
• lemah = weak in a broader sense, including physical weakness, lack of strength, or even weakness in an abstract sense

In this sentence, lemas is the best choice because it describes the physical feeling of low energy from not eating.

Examples:

• Saya lemas karena belum makan. = I feel weak because I haven’t eaten.
• Dia lemah dalam matematika. = He is weak in math.

So lemas is more natural for that tired, faint, low-energy body feeling.

Yes. In Indonesian, adjectives and many descriptive words can directly function as the predicate of a sentence.

So these are complete and natural:

• Perut saya kosong.
• Badan saya lemas.

There is no need to add a word meaning is.

This is one of the major differences from English.

Dan means and. It links the two results:

• perut saya kosong
• badan saya terasa lemas

So the structure is:

Cause: Saya belum sarapan
Result 1: perut saya kosong
Result 2: badan saya terasa lemas

Yes, it could be split into separate sentences:

• Saya belum sarapan. Jadi perut saya kosong. Badan saya terasa lemas.

But the original version flows more naturally as one connected thought.

Yes, but the meaning changes slightly.

• Saya belum sarapan = I haven’t had breakfast yet
• Saya belum makan = I haven’t eaten yet

Belum makan is broader. It does not specifically mention breakfast.
If the point is that you skipped breakfast, belum sarapan is more precise.

It is mostly neutral and natural. It works well in everyday speech and writing.

A very casual spoken version might be shorter, for example:

• Aku belum sarapan, jadi perutku kosong dan badanku lemas.

Differences:

• aku instead of saya = more casual
• perutku instead of perut saya = attached possessive, also common and casual
• badanku instead of badan saya

The original sentence with saya sounds polite and standard.

Yes, tubuh saya terasa lemas is understandable and grammatical.

However, badan often sounds more natural in everyday speech when talking about how your body feels physically.

Very roughly:

• badan = common, everyday word for body
• tubuh = also body, but sometimes a bit more formal or anatomical in tone

So in this sentence, badan saya terasa lemas sounds very natural.

A simple way to break it down is:

Saya belum sarapan, jadi perut saya kosong dan badan saya terasa lemas.

1. Saya = subject
2. belum sarapan = predicate: have not had breakfast yet
3. jadi = connector: so / therefore
4. perut saya kosong = first result clause
5. dan = and
6. badan saya terasa lemas = second result clause

So the pattern is:

[cause], jadi [result 1] dan [result 2]

This is a very useful pattern in Indonesian.
