3.6 Effective Sentences (Kalimat Efektif)
Key Takeaways
- Kalimat efektif has seven characteristics: kesepadanan, keparalelan, ketegasan, kehematan, kecermatan, kelogisan, kepadatan.
- Pleonasm is the most tested defect: 'para siswa-siswa' (redundant plural), 'agar supaya' (redundant conjunction), 'saling berhadap-hadapan' (saling already implies mutual).
- Active voice (meN- prefix) is preferred over passive for clarity and directness; passive (di-) is used when the patient is the topic.
- Three common sentence errors: kalimat tidak bertema (no topic), subjek ganda (double subject, e.g. 'Bapak Ahmad beliau...'), predikat tidak sejajar (non-parallel predicates).
- Diagnostic for parallel predicates: all items in a series should share the same affixed verb form (membaca, menulis, bermain — not membaca, penulis, bermain).
Effective Sentences (Kalimat Efektif)
Quick Answer: A kalimat efektif is a sentence that achieves its communicative purpose with minimum effort and maximum clarity. UKBI tests seven characteristics — kesepadanan, keparalelan, ketegasan, kehematan, kecermatan, kelogisan, kepadatan — and three common errors: kalimat tidak bertema, subjek ganda, and predikat tidak sejajar.
The Seven Characteristics
| Characteristic | Meaning | Test |
|---|---|---|
| Kesepadanan | Balance: subject and predicate match in person, number, and structure | Mereka sedang belajar (balanced) vs Mereka sedang belajar bahasa Indonesia itu (unbalanced) |
| Keparalelan | Parallelism: items in a series share grammatical form | Ia suka membaca, menulis, dan bermain (parallel) vs Ia suka membaca, menulis, dan main (not parallel) |
| Ketegasan | Emphasis: the main idea stands out, usually by placing it at sentence start or end | Bukan uang yang dicari, melainkan ilmu (emphatic) |
| Kehematan | Efficiency: no redundant words or structures | Use para siswa OR siswa-siswa, not both |
| Kecermatan | Precision: every word is exact and unambiguous | Banyak orang (countable) vs Banyak air (uncountable — should be banyaknya air) |
| Kelogisan | Logicality: the sentence makes sense and the parts connect rationally | Karena hujan, maka ia basah (logical) vs Karena hujan, ia mendengkur (illogical) |
| Kepadatan | Conciseness: idea is packed tightly, no padding | Ia menulis surat (padat) vs Ia menulis sebuah surat yang berisi tulisan (loose) |
Subject-Predicate Agreement (Kesepadanan)
The subject determines the predicate's form. Common mismatches:
- Plural subject with singular verb: Mereka sedang membaca — Indonesian verbs are not inflected for number, so this is fine. But Mereka adalah seorang dokter is wrong — mereka (plural) cannot be seorang (singular).
- Two subjects with one predicate meant for only one: Bapak Ahmad dan saya pergi ke kantor — if both went, this is correct. If only "saya" went, the sentence is ambiguous.
- Subject hidden by a passive: Surat itu ditulis oleh Ahmad — fine. Surat itu ditulis oleh saya Ahmad — wrong, mixed voice.
Avoiding Redundancy (Kehematan)
Redundancy — pleonasm — is the most heavily tested error in kalimat efektif. Common pleonasms:
| Redundant phrase | Efficient form | Why |
|---|---|---|
| para siswa-siswa | para siswa or siswa-siswa | para already marks plural |
| saling berhadap-hadapan | saling berhadapan | saling already means mutual |
| agar supaya | agar or supaya | both mean "in order to" |
| sedari dari | sejak or dari | double "from" |
| yang mana itu | itu | redundant demonstrative |
| masing-masing para siswa | masing-masing siswa | para clashes with masing-masing |
| pada waktu ketika | ketika | double temporal |
| adalah merupakan | adalah or merupakan | both mean "is/are" — pick one |
When you see a kalimat efektif item, scan first for pleonasm — it is the single most common defect.
Active vs Passive Choice
Indonesian allows both active (meN- prefix) and passive (di- prefix) constructions. Active is preferred for clarity and directness:
- Active (preferred): Ahmad menulis surat itu. (Ahmad wrote the letter.)
- Passive (when the doer is unknown or unimportant): Surat itu ditulis oleh Ahmad. OR Surat itu sudah ditulis.
Use passive when the patient (object) is the topic of the surrounding discourse. Use active when the agent is the focus. UKBI items often present a sentence in passive voice that should be active, or vice versa, and ask you to identify the more effective form.
Three Common Sentence Errors
1. Kalimat Tidak Bertema (No Clear Topic)
The sentence has no main idea; the reader cannot tell what is being said.
Tidak baku: Buku ini sangat tebal dan berat, ditulis oleh seorang professor yang sudah lama mengajar di universitas terkenal, judulnya pun panjang.
This sentence packs three unrelated ideas (physical description, author info, title) into one without a main topic. Fix by splitting or choosing one topic: Buku ini tebal dan berat.
2. Subjek Ganda (Double Subject)
Two subjects appear for one predicate. The most common pattern is a name plus a pronoun:
Tidak baku: Bapak Ahmad beliau pergi ke kantor pagi-pagi.
Both Bapak Ahmad and beliau function as subject. Fix by removing one: Bapak Ahmad pergi ke kantor pagi-pagi. OR Beliau pergi ke kantor pagi-pagi.
3. Predikat Tidak Sejajar (Non-parallel Predicates)
When a sentence lists actions or qualities, they should share grammatical form:
Baku: Ia membaca buku, menulis surat, dan bermain bola di lapangan.
This is parallel — all verbs in the same form. Compare:
Tidak baku: Ia membaca buku, penulis surat, dan bermain bola.
Here penulis (noun) breaks the parallelism; it should be menulis (verb).
How to Spot the Ineffective Sentence
For a Merespons Kaidah item asking which part of a sentence is ineffective:
- Read the whole sentence once for topic.
- Identify subject and predicate — check for doubling.
- Check each series for parallel form.
- Scan for pleonasm using the table above.
- Check voice — passive where active is clearer (or vice versa).
These five checks catch the overwhelming majority of kalimat efektif items.
