Saya ingin belajar lebih serius tentang bumbu dapur, jadi saya menulis nama-nama seperti jahe, kunyit, dan ketumbar di buku catatan.

Because Indonesian often repeats the subject when a new clause begins, especially after a connector like jadi (so).

• Saya ingin belajar lebih serius tentang bumbu dapur = I want to study kitchen spices more seriously
• jadi saya menulis... = so I wrote / so I write...

In English, we also usually repeat the subject: ..., so I wrote...
You normally would not drop saya here.

Ingin means to want and often sounds a bit more neutral, careful, or formal than mau.

• Saya ingin belajar = I want to study / learn
• Saya mau belajar = I want to study / learn

Both are common and natural. In many everyday situations, mau is more conversational, while ingin can sound slightly more polished.

Belajar means to study or to learn in a general sense.

• belajar tentang bumbu dapur = study/learn about kitchen spices

If you say mempelajari, it means to study something in a more direct, often more formal or deliberate way.

• Saya ingin mempelajari bumbu dapur = I want to study kitchen spices

So in this sentence, belajar tentang... is a very natural way to say learn about...

Lebih means more.

So:

• serius = serious
• lebih serius = more serious / more seriously

In this sentence, belajar lebih serius means to study more seriously. Indonesian often uses an adjective where English might use an adverb.

In Indonesian, adjectives often do the job that adverbs do in English.

So:

• belajar serius literally looks like study serious
• but the real meaning is study seriously

Likewise:

• bicara pelan = speak slowly/softly
• kerja keras = work hard

So lebih serius naturally means more seriously in context.

Tentang means about.

• belajar tentang bumbu dapur = learn about kitchen spices

It introduces the topic of study. This is very common after verbs like belajar, bicara, membaca, or menulis when you want to say what something is about.

Bumbu dapur literally means something like kitchen seasonings/spices.

• bumbu = seasoning, spice mixture, flavoring
• dapur = kitchen

Together, bumbu dapur refers to common cooking spices or seasonings used in the kitchen. Depending on context, it can include spices, herbs, and flavoring ingredients.

Indonesian does not have articles like a, an, or the.

So:

• bumbu dapur can mean kitchen spices, the kitchen spices, or some kitchen spices
• buku catatan can mean a notebook or the notebook

The exact meaning depends on context, not on a separate article.

Here, jadi means so or therefore.

It connects the first idea to the result:

• I want to study kitchen spices more seriously,
• so I write down names like ginger, turmeric, and coriander in my notebook.

Be careful: jadi can also mean become in other sentences.

• Dia jadi guru = He/She became a teacher

Menulis is the active verb form with the meN- prefix.

• tulis = write / writing root
• menulis = to write

In normal standard Indonesian, when the subject actively does something, the meN- form is very common:

• Saya menulis surat = I write / wrote a letter

Using just tulis would sound incomplete or nonstandard in this kind of sentence.

The repetition (reduplication) often shows plurality.

• nama = name
• nama-nama = names

So menulis nama-nama means to write down names.

That said, Indonesian does not always need reduplication to show plural. Sometimes context is enough. But here nama-nama clearly emphasizes that several names were written.

Yes. Seperti means like or such as.

So:

• nama-nama seperti jahe, kunyit, dan ketumbar = names such as ginger, turmeric, and coriander

This suggests these are examples, not necessarily the complete list.

In this sentence, seperti is a preposition meaning like or such as.

It introduces examples:

• buah seperti apel dan mangga = fruits such as apples and mangoes
• warna seperti merah dan biru = colors like red and blue

They are names of spices:

• jahe = ginger
• kunyit = turmeric
• ketumbar = coriander

A learner should note that spice vocabulary can vary a little by context in English, especially with words like coriander depending on whether you mean seeds, powder, or the plant.

Both can be possible, but di buku catatan is very natural for in/on the notebook, especially when talking about writing something there.

• Saya menulis ... di buku catatan = I wrote ... in my notebook / in the notebook

Di is a general location marker: at, in, on depending on context.

Dalam specifically means inside and can sometimes feel more physical or more emphatic.

Buku catatan means notebook or note-taking book.

• buku = book
• catatan = notes, record, written notes

Together, it refers to a notebook. Indonesian often forms noun phrases this way, where the second noun describes the first.

In Indonesian noun phrases, the main noun usually comes first, and the describing noun comes after it.

• buku catatan = note book / notebook
• rumah makan = eating house / restaurant
• kamar tidur = sleeping room / bedroom

So buku is the head noun, and catatan describes what kind of book it is.

Indonesian verbs do not change form for tense the way English verbs do. So menulis by itself does not tell you whether it is present or past.

Depending on context, this could mean:

• I write down names...
• I wrote down names...

If the speaker wanted to make the past clearer, they might add a time word such as:

• kemarin = yesterday
• tadi = earlier

Because Indonesian does not need a separate word equivalent to English to in this pattern.

• Saya ingin belajar = I want to learn

The structure is simply:

• subject + ingin + verb

This is normal and very common in Indonesian.

Yes, and the nuance would be a little different.

• menulis = to write
• mencatat = to note down, record, take note of

So:

• Saya menulis nama-nama... = I wrote the names...
• Saya mencatat nama-nama... = I noted down the names...

Since the sentence talks about writing names in a notebook, mencatat would also be very natural. Menulis focuses more on the act of writing; mencatat focuses more on making notes.
