Nominalizing an event changes its syntax without erasing its participants. In Pemerintah membangun jembatan, the government is actor and the bridge affected entity. In pembangunan jembatan oleh pemerintah, pembangunan is a noun, jembatan follows as its event-defining participant, and oleh pemerintah reintroduces the actor.
This page develops that valency shift, contrasts neighboring nominalizers, and shows how lexicalization and register shape actual choices. Formation belongs on the adjacent formation page; the meaning page maps process, result, and institutional readings.
From active clause to event noun phrase
The four required families illustrate the recurrent mapping.
| Active clause | Event noun phrase | Participant mapping |
|---|---|---|
| Pemerintah membangun jembatan. | pembangunan jembatan oleh pemerintah | built entity + actor |
| Dosen mengajar sintaksis. | pengajaran sintaksis oleh dosen | content + instructor |
| Tim meneliti kualitas air. | penelitian kualitas air oleh tim | topic/entity examined + researcher |
| Panitia mengumumkan hasil seleksi. | pengumuman hasil seleksi oleh panitia | content + announcer |
Pemerintah daerah membangun jembatan baru di atas sungai itu.
The regional government is building a new bridge over that river.
Pembangunan jembatan baru oleh pemerintah daerah dimulai bulan ini.
Construction of the new bridge by the regional government begins this month.
Dosen baru itu mengajarkan sintaksis kepada mahasiswa tingkat akhir.
The new lecturer teaches syntax to final-year students.
Pengajaran sintaksis oleh dosen baru itu mendapat tanggapan positif.
The new lecturer's teaching of syntax received positive feedback.
Tim independen meneliti kualitas air di sekitar pabrik.
An independent team is researching water quality around the factory.
Penelitian kualitas air oleh tim independen berlangsung selama enam bulan.
The independent team's research on water quality lasted six months.
Panitia akan mengumumkan hasil seleksi malam ini.
The committee will announce the selection results tonight.
Pengumuman hasil seleksi oleh panitia dijadwalkan malam ini.
The committee's announcement of the selection results is scheduled for tonight.
A following noun is not a verbal object
In pembangunan jembatan, pengajaran sintaksis, and penelitian kualitas air, the following phrase identifies what defines the event. The nominal head itself cannot assign voice or tense as a verb does.
Pembangunan jalan pesisir memerlukan izin lingkungan.
Construction of the coastal road requires an environmental permit.
Pengajaran bahasa Indonesia kepada penutur asing memerlukan konteks budaya.
Teaching Indonesian to foreign-language speakers requires cultural context.
Penelitian tentang perubahan iklim itu menggunakan data selama tiga puluh tahun.
That research on climate change uses thirty years of data. (academic)
Direct juxtaposition is common with a compact, conventional relation: penelitian kualitas air. A preposition such as tentang or terhadap can clarify topic or target, especially with a heavy phrase.
Penelitian terhadap dampak kebijakan tersebut belum selesai.
Research into the impact of that policy is not yet complete. (academic)
Do not add verbal meN- morphology to the dependent noun. The phrase is not penelitian meneliti kualitas air; event meaning is already in penelitian.
Expressing the actor
An actor can appear with oleh, as a possessor-like noun immediately after a complete event phrase, or remain implicit.
Pemeriksaan kendaraan oleh petugas berlangsung sekitar sepuluh menit.
The vehicle inspection by the officer takes about ten minutes.
Penelitian tim kami berfokus pada kualitas udara dalam ruangan.
Our team's research focuses on indoor air quality.
Pengiriman barang akan dilanjutkan setelah cuaca membaik.
Goods delivery will resume after the weather improves.
Oleh is clearest when both an affected entity and actor are expressed: pemeriksaan kendaraan oleh petugas. In penelitian tim kami, lexical plausibility makes the team an actor/owner, but bare juxtaposition can become ambiguous.
Pembangunan pemerintah mendapat kritik dari warga.
Government development/construction drew criticism from residents; the participant relation is unclear.
This phrase could suggest development of the government, development carried out by it, or a government program. State the event participant explicitly:
Pembangunan proyek oleh pemerintah mendapat kritik dari warga.
The government's construction of the project drew criticism from residents.
Aspect and modality move outside the noun
The circumfix does not mark whether an event is ongoing, complete, planned, or merely possible. Surrounding predicates and modifiers do that work.
Pengumpulan data sedang berlangsung.
Data collection is currently in progress.
Pengumpulan data telah selesai.
Data collection has been completed. (formal)
Pengumpulan data mungkin ditunda sampai bulan depan.
Data collection may be postponed until next month.
The temporal or modal element belongs to the larger clause: sedang berlangsung, telah selesai, mungkin ditunda. By contrast, a finite active clause places it before the verb:
Tim sedang mengumpulkan data di lapangan.
The team is currently collecting data in the field.
This difference is why sedang pengumpulan data is not a complete neutral predicate. Use sedang berlangsung or restore a finite verb.
Choosing participant, event, and result nouns
Neighboring affixes profile different facets of the same family.
| Base | Participant | Event/process | Result/content |
|---|---|---|---|
| bangun | pembangun builder | pembangunan construction | bangunan building |
| ajar | pengajar instructor | pengajaran teaching | ajaran teaching/doctrine |
| teliti | peneliti researcher | penelitian research/study | hasil penelitian research findings |
| umum | no equally common neutral agent noun | pengumuman announcing/announcement | pengumuman announcement content |
Pembangun gedung itu menggunakan bahan dari pemasok lokal.
The builder of that building uses materials from a local supplier.
Pembangunan gedung itu hampir selesai.
Construction of that building is almost complete.
Bangunan itu belum boleh digunakan.
That building cannot be used yet.
Para peneliti sedang membahas hasil penelitian terbaru.
The researchers are discussing the latest research findings.
There is no universal one-slot paradigm. Pengumuman itself covers event and content; “announcer” usually requires a lexical role such as pembawa acara or an active clause, depending on context.
Lexicalized institutions and locations have their own complements
Location nouns behave like ordinary lexical nouns even if their history is eventive.
Kami memesan kamar di penginapan dekat stasiun.
We booked a room at lodging near the station.
Pengadilan negeri itu menangani perkara perdata.
That district court handles civil cases. (formal)
Penampungan sementara membutuhkan tambahan selimut.
The temporary shelter needs additional blankets.
The inn is not an “ongoing staying process,” and the court is not merely an “act of judging.” Their modern countability, modifiers, and institutional meanings must be learned lexically.
Result-like words behave similarly:
Pendapatan bulanan keluarga itu tidak tetap.
That family's monthly income is not fixed.
Dari teras hotel, kami dapat menikmati pemandangan laut.
From the hotel terrace, we can enjoy a view of the sea.
Morphological possibility does not predict these modern collocations.
Formal nominal style and conversational clauses
Event nouns are dense and useful in formal, bureaucratic, journalistic, and academic prose. Conversation often foregrounds an actor with a finite verb.
Bangun → pembangunan
Pembangunan fasilitas kesehatan akan dilaksanakan secara bertahap.
Construction of the healthcare facility will be carried out in stages. (formal)
Pemerintah bakal bangun kliniknya bertahap.
The government is going to build the clinic in stages. (informal)
Ajar → pengajaran
Metode pengajaran tersebut akan dievaluasi pada akhir semester.
That teaching method will be evaluated at the end of the semester. (formal)
Cara gurunya ngajar bakal dinilai akhir semester.
The way the teacher teaches will be assessed at the end of the semester. (informal)
Teliti → penelitian
Penelitian mengenai kualitas udara sedang dilaksanakan oleh tim independen.
Research on air quality is being conducted by an independent team. (academic)
Tim independennya lagi meneliti kualitas udara.
The independent team is researching air quality right now. (informal)
Umum → pengumuman
Pengumuman hasil seleksi akan disampaikan melalui laman resmi.
The selection-results announcement will be issued through the official website. (formal)
Nanti panitia kasih tahu hasilnya di situs.
The committee will let everyone know the results on the site later. (informal)
The conversational paraphrases are not shortened nominalizations. They reorganize the message around an actor and action. Informal ngajar is a recognized colloquial active form; retain mengajar in careful Standard Indonesian.
Avoid uncontrolled nominal stacking
Several event nouns can form a grammatical but difficult chain. Readers must infer every participant relation.
Pelaksanaan peningkatan pengawasan pengiriman barang akan dievaluasi.
The implementation of increased monitoring of goods delivery will be evaluated. (formal but dense)
For clearer prose, restore actors and verbs:
Tim akan mengevaluasi cara petugas meningkatkan pengawasan terhadap pengiriman barang.
The team will evaluate how officers improve monitoring of goods delivery.
Nominal style is useful when the event itself is the stable topic. It becomes costly when several hidden actors and affected entities accumulate.
Productive schema and blocked formations
PeN-...-an readily creates technical event nouns, but the active verb does not guarantee one predictable noun. Loan clusters, internal suffixes, and existing synonyms can block or reshape a candidate. Verify unfamiliar forms rather than converting English -tion mechanically.
Orthography
Write actual words solid: pembangunan, pengajaran, penelitian, pengumuman. Use peN-...-an only as the abstract label. Nasal substitution remains visible in the noun; do not restore t in penelitian or k in pengiriman.
Common Mistakes
1. Using an agent noun for an event
❌ Peneliti lapangan berlangsung selama enam minggu.
Wrong for the activity — peneliti means researcher.
✅ Penelitian lapangan itu memerlukan waktu enam minggu.
That field research requires six weeks.
2. Using an event noun as a finite verb
❌ Panitia pengumuman hasil seleksi malam ini.
Incorrect — pengumuman is a noun, not the finite verb ‘announce.’
✅ Panitia mengumumkan hasil seleksi malam ini.
The committee announces the selection results tonight.
3. Leaving the actor relation ambiguous
❌ Pembangunan pemerintah dihentikan warga.
Ambiguous — it is unclear what is built and how pemerintah participates.
✅ Pembangunan proyek oleh pemerintah dihentikan warga.
The government's construction of the project was stopped by residents.
4. Putting sedang directly before an event noun
❌ Tim itu sedang penelitian kualitas air.
Incorrect predicate structure — use a finite verb or state that the research is ongoing.
✅ Tim itu sedang meneliti kualitas air.
That team is researching water quality.
5. Confusing event and result entity
❌ Pembangunan tua itu akan direnovasi.
Wrong for a physical structure — pembangunan names construction/development.
✅ Bangunan tua itu akan direnovasi.
That old building will be renovated.
Key Takeaways
- Event nominalization reorganizes verbal participants as nominal dependents rather than erasing them.
- Place the affected entity or content after the noun; use oleh for an actor when clarity requires it.
- Aspect and modality belong outside the noun: pengumpulan sedang berlangsung.
- Contrast participant, event, and result families before choosing a derivative.
- Match nominal density to register, and treat lexicalized places and results as complete vocabulary items.
