Complex Sentence Structures in Indonesian

In Brief

Indonesian links clauses (sentence parts that express separate ideas) with connectors such as karena “because,” jika/kalau “if,” and walaupun/meskipun “although.” Full pairs such as jika...maka and bukan hanya...tetapi juga make the relationship especially explicit, but not every apparent pair must be completed: in concise formal prose, Karena hujan, saya terlambat is often preferable to Karena hujan, maka saya terlambat.

Overview

A complex sentence brings together a main clause (the part that can carry the central message) and one or more dependent clauses (parts whose role is to give a cause, condition, contrast, purpose, or other background). Indonesian does not need tense agreement or special verb forms to do this. The logic is mainly carried by connectors, clause order, context, and punctuation.

At B2, the challenge is therefore not memorizing a long set of endings. It is choosing a structure that shows exactly how two ideas relate. Compare Hujan. Saya terlambat. “It rained. I was late.” with Karena hujan, saya terlambat. “Because it rained, I was late.” The second version guides the reader to interpret rain as the cause.

English-speaking learners will recognize many of the logical patterns. The important difference is that Indonesian has several paired constructions that are useful in careful argument, while everyday speech often leaves the second member unstated. Formal Indonesian also has a strong preference for balanced, economical clauses. A pair that sounds emphatic in a speech may be edited down in a report.

How It Works

Start with the relationship between the clauses

Choose the connector according to the logic, not simply according to the English word you would translate.

Relationship	Common Indonesian pattern	Core meaning
Cause → result	karena A, B; A sehingga B	because A, B; A, with the result that B
Condition → consequence	jika/kalau A, (maka) B	if A, (then) B
Concession → unexpected outcome	walaupun/meskipun A, B	although A, B
Balanced addition	bukan hanya A, tetapi juga B	not only A, but also B
Alternative	baik A maupun B	both A and B / whether A or B, according to context
Proportional change	semakin A, semakin B	the more A, the more B

A dependent clause can come first or second:

• Karena jalan itu banjir, bus tidak dapat lewat. — Because the road was flooded, the bus could not pass.
• Bus tidak dapat lewat karena jalan itu banjir. — The bus could not pass because the road was flooded.

When the dependent clause comes first, a comma helps the reader see the boundary. When it follows the main clause, Indonesian normally does not place a comma before it.

Cause: karena, maka, and sehingga

Karena introduces a cause. The result can follow directly:

Karena rapat dimulai lebih awal, kami berangkat pukul tujuh.
Because the meeting started earlier, we left at seven.

Maka presents a consequence or conclusion, roughly “therefore” or “then.” It is common in logical explanations, formal declarations, narratives, and fixed rhetorical patterns. The full shape karena A, maka B occurs widely and makes the progression unmistakable. However, many editors consider maka unnecessary after a clause already introduced by karena. In neutral, concise writing, use either:

• Karena A, B — Because A, B.
• A. Oleh karena itu, B. — A. Therefore, B.

Do not confuse cause with result. Sehingga introduces a result, not the reason:

• Hujan turun sangat deras sehingga jalan itu banjir. — It rained so heavily that the road flooded.
• Karena jalan itu banjir, sekolah ditutup. — Because the road flooded, the school was closed.

Conditions: kalau/jika...maka

Kalau and jika both introduce conditions. Kalau is very common in conversation; jika is frequent in formal instructions, policies, and careful writing. Apabila is another formal option, especially in rules and official notices.

Maka is optional in most conditional sentences. It can be useful when the condition is long, because it clearly marks where the consequence begins:

Jika seluruh persyaratan telah dipenuhi sebelum batas waktu, maka permohonan akan diproses pada hari kerja berikutnya.

With a short condition, dropping it usually sounds lighter:

Kalau ada waktu, pergilah ke museum itu.

Indonesian verbs do not change into a special conditional mood. Time is inferred from context or stated with words such as nanti “later,” akan “will,” sudah “already,” and kemarin “yesterday.”

Concession: walaupun and meskipun

A concession is a fact that might lead you to expect one result, followed by a different or surprising result:

Walaupun lelah, dia tetap menyelesaikan laporan itu.
Although tired, she still finished the report.

Walaupun and meskipun are close in meaning. Meskipun often feels slightly more suited to careful written prose, but both are standard and common. In the main clause, tetap “still/nevertheless” is a natural way to emphasize that the outcome continued despite the obstacle.

The pattern walaupun/meskipun...tetapi/namun... is heard and read, especially when a speaker wants an explicit contrast. Yet conservative editing often removes one of the two conjunctions:

• Concise: Meskipun anggarannya terbatas, proyek itu tetap berjalan.
• Two independent sentences: Anggarannya terbatas. Namun, proyek itu tetap berjalan.

Here namun works especially well as a sentence-level transition (“however”). Tetapi normally joins contrasting elements or clauses within one sentence.

True paired connectors

Some constructions are genuinely balanced: both members are important.

bukan hanya...tetapi juga

This pair adds a second point and emphasizes that the first is not the whole story:

Program itu bukan hanya murah, tetapi juga mudah digunakan.
The program is not only inexpensive but also easy to use.

Keep the two sides parallel—that is, built in the same grammatical shape. Match adjective with adjective, noun phrase with noun phrase, or verb phrase with verb phrase.

For a correction rather than simple addition, bukan...melainkan... is often better:

Masalahnya bukan kekurangan dana, melainkan pengelolaan yang buruk.
The problem is not a lack of funds, but poor management.

baik...maupun and semakin...semakin

Baik...maupun... presents two included alternatives or groups:

Baik peserta baru maupun peserta lama wajib mendaftar ulang.
Both new and returning participants must register again.

Semakin...semakin... shows two linked changes:

Semakin sering Anda berlatih, semakin lancar Anda berbicara.
The more often you practice, the more fluently you speak.

Combining more than two clauses

Long sentences stay readable when each connector has one clear job:

Meskipun hujan belum berhenti, panitia memutuskan bahwa acara akan dimulai karena sebagian besar peserta sudah hadir.

The outer relationship is concession (meskipun...); bahwa introduces the content of the decision; karena gives the reason. Before writing a sentence like this, identify the central message: panitia memutuskan... “the committee decided....” Attach each supporting idea to that center rather than stacking unrelated details.

Examples in Context

Indonesian	English	Note
Karena hujan, maka saya terlambat.	Because it rained, I arrived late.	Explicit cause–result pattern; often shortened in edited prose.
Karena kereta dibatalkan, kami mengikuti rapat secara daring.	Because the train was canceled, we attended the meeting online.	Neutral cause clause without maka.
Permintaan meningkat tajam sehingga persediaan cepat habis.	Demand rose sharply, so the stock ran out quickly.	Sehingga introduces the result.
Kalau ada waktu, maka pergilah.	If there is time, then go.	Maka is possible, though optional with this short condition.
Jika kata sandi Anda terlupa, hubungi petugas layanan.	If you forget your password, contact the service officer.	Jika suits a written instruction.
Apabila pembayaran belum diterima, pesanan tidak akan dikirim.	If payment has not been received, the order will not be sent.	Formal condition used in policies.
Walaupun miskin, tetapi bahagia.	Although poor, still happy.	Understandable elliptical slogan; a full neutral sentence would state the subject.
Walaupun lelah, mereka tetap bekerja dengan teliti.	Although tired, they continued to work carefully.	Tetap naturally reinforces the unexpected outcome.
Meskipun pendapat kami berbeda, kami menghormati keputusan bersama.	Although our opinions differ, we respect the joint decision.	Concise formal concession.

Semakin lama keputusan ditunda, semakin besar biayanya.	The longer the decision is delayed, the greater the cost.	Two proportional changes.

Common Mistakes

Treating every connector as a mandatory pair

• Awkward in concise prose: Karena listrik padam, maka rapat dibatalkan.
• Better: Karena listrik padam, rapat dibatalkan.
• Why: The meaning is already clear after karena. The version with maka exists and may be emphatic, but many editors prefer the shorter structure.

Using sehingga for a cause

• Wrong: Sehingga hujan deras, pertandingan ditunda.
• Right: Karena hujan deras, pertandingan ditunda.
• Why: Karena introduces the reason. Sehingga introduces what happened as a result.

Doubling concession without considering register

• Heavy: Walaupun dia sibuk, tetapi dia datang.
• Neutral: Walaupun dia sibuk, dia tetap datang.
• Why: The first version is common enough to recognize, but walaupun + tetap gives a cleaner subordinate-clause structure in edited Indonesian.

Losing parallel structure

• Wrong: Kursus itu bukan hanya praktis, tetapi juga mengajarkan teori.
• Right: Kursus itu bukan hanya mengajarkan keterampilan praktis, tetapi juga menjelaskan teori.
• Why: After a paired connector, matching grammatical shapes make the comparison easy to follow.

Translating English “then” mechanically

• Unnatural: Kalau kamu lapar, maka kemudian makanlah.
• Right: Kalau kamu lapar, makanlah.
• Why: Maka and kemudian are not required copies of English “then.” Kemudian marks a later step in time; maka marks a logical consequence.

Writing a long chain with no clear center

• Hard to follow: Karena datanya berubah dan jika tim setuju maka meskipun waktunya singkat tetapi laporan diperbarui.
• Better: Meskipun waktunya singkat, laporan akan diperbarui jika tim setuju, karena datanya telah berubah.
• Why: Decide which clause carries the main message, then attach condition, cause, and concession in a logical order.

Usage Notes

In conversation, kalau is usually more relaxed than jika or apabila. Speakers also rely heavily on context: Kalau hujan, nggak jadi can mean “If it rains, it’s off,” even though the subject is unstated. Nggak is informal; use tidak in formal writing.

Formal prose favors explicit logic, but “explicit” does not mean “use as many connectors as possible.” Jika...maka can help readers navigate a long regulation or argument. By contrast, adding maka to every short condition becomes repetitive. Likewise, namun is effective between sentences or after a semicolon, while tetapi is the ordinary choice for contrast inside a sentence.

Punctuation supports the structure but does not create it. Put a comma after a dependent clause placed before the main clause: Jika ada perubahan, kami akan memberi tahu Anda. Usually omit it when that clause comes second: Kami akan memberi tahu Anda jika ada perubahan.

Beyond the Basics / Advanced Use

Advanced writing often uses nominalization (turning an action or quality into a noun-like expression) to pack information into clauses: Karena terjadinya peningkatan biaya... “Because of the occurrence of a cost increase....” Such forms are common in bureaucratic writing, but a direct clause is often clearer: Karena biaya meningkat... “Because costs increased....” Complexity should serve precision, not merely make the sentence sound official.

Be alert to scope, meaning exactly which words a connector applies to. Compare:

• Dia tidak hanya membaca laporan itu, tetapi juga membahasnya. — She not only read the report but also discussed it.
• Tidak hanya dia yang membaca laporan itu, tetapi juga atasannya. — It was not only she who read the report, but also her supervisor.

Moving tidak/bukan hanya changes whether the contrast concerns the actions or the people.

Indonesian can also leave repeated material unstated when the balance remains obvious: Semakin cepat, semakin baik “The sooner, the better.” This is ellipsis (omitting words that listeners can recover). It is elegant in familiar patterns but can become ambiguous in a dense argument. Repeat the necessary noun or verb when clarity matters.

Finally, distinguish logical maka from narrative maka. In stories or solemn language, maka may advance events: Maka berangkatlah mereka ke istana “Then they set off for the palace.” This elevated narrative use is not the same as the optional result marker in jika...maka.

Practice Tips

1. Take five pairs of short sentences and combine each pair three ways: with a cause (karena), a condition (jika), and a concession (meskipun). Notice how the logical meaning changes.
2. Highlight connectors in a news article or official notice. For each one, label the clauses “cause,” “result,” “condition,” “contrast,” or “addition,” then ask whether the second connector is necessary.
3. Build paired sentences in matching shapes: adjective + adjective, noun phrase + noun phrase, and verb phrase + verb phrase. Read them aloud to hear whether bukan hanya...tetapi juga is balanced.
