D.Peraturan Menteri Tenaga Kerja No. Per-02/MEN/1992
Explanation: Undang-Undang No. 1 Tahun 1970 tentang Keselamatan Kerja is Indonesia's foundational OSH statute. It establishes the legal duty to protect worker safety, prevent accidents, control mechanical and chemical hazards, and ensure safe working environments across all workplaces on land, underground, on water surfaces, in water, and in the air within national jurisdiction.
2How does Article 1 paragraph (2) of Undang-Undang No. 1 Tahun 1970 define the term 'pengurus' (workplace manager or person in charge)?

Explanation: Under Article 1 paragraph (2) of UU No. 1 Tahun 1970, 'pengurus' is defined as the person who directly manages or leads a workplace or an independent part thereof.

B.The right to demand that management replace mandatory PPE with cash hazard allowances
C.The right to refuse to join a workplace safety committee without disciplinary penalty
D.The right to unilaterally issue statutory stop-work notices to third-party contractors
Explanation: UU No. 1 Tahun 1970 Pasal 12 huruf (d) gives workers the right to state objections to performing work where the required safety and health measures and the mandatory personal protective equipment are in doubt, except in special cases decided otherwise by an authorised official within safe limits. The same article pairs that right with duties: to give accurate information to the inspector, to wear the required protective equipment, and to comply with the OSH requirements in force.

6What is the statutory validity period of a Surat Keputusan Penunjukan (SKP) and Lisensi Kewenangan Ahli K3 issued by Kemnaker under Permenaker No. Per-02/MEN/1992?
A.1 year, renewable annually through the provincial labor office
B.3 years, renewable upon application by the employing company

7Under Pasal 8 of Permenaker No. Per-02/MEN/1992, which situation causes an Ahli K3 appointment decree (SKP) to stop applying or to be revoked?
A.The Ahli K3 fails to achieve zero accidents within the enterprise over a 12-month period
B.The company experiences a financial loss or undergoes a corporate merger
C.The Ahli K3 joins a registered labor union or professional safety association
D.The Ahli K3 moves to another company or institution, or is proven to have disclosed a company secret that the position obliged them to keep
Explanation: Permenaker No. Per-02/MEN/1992 Pasal 8 ayat (1) states that the appointment decree stops applying (tidak berlaku) if the holder moves to another company or institution, resigns, or dies. Pasal 8 ayat (2) allows the decree to be revoked (dicabut) if the holder is proven to have failed to comply with OSH legislation, to have made an error or act of carelessness that created a dangerous condition, or to have disclosed — deliberately or through oversight — a company or institution secret that the position obliged them to keep.

Explanation: Permenaker No. Per-04/MEN/1987 Pasal 1 huruf d defines P2K3 as a badan pembantu (auxiliary body) at the workplace that acts as the forum for cooperation between the employer and workers to develop cooperation, mutual understanding, and effective participation in applying occupational safety and health. Pasal 4 ayat (1) then gives it the task of advising the employer on OSH matters, whether or not that advice is requested.
9What does Pasal 3 of Permenaker No. Per-04/MEN/1987 require about the composition of a P2K3?
A.Membership is drawn only from management; workers may attend as observers without voting rights
B.The Secretary must be an external labor inspector and the Chairman must be the company doctor
C.The committee is formed unilaterally by the workers' union and the employer is notified afterwards
D.Membership combines employer and worker elements as Chairman, Secretary, and Members, with the enterprise's own Ahli Keselamatan Kerja serving as Secretary
Explanation: Permenaker No. Per-04/MEN/1987 Pasal 3 ayat (1) states that P2K3 membership is drawn from both the employer element and the worker element, structured as a Chairman (Ketua), a Secretary (Sekretaris), and Members (Anggota). Ayat (2) names only one post: the Secretary is the Ahli Keselamatan Kerja of the enterprise concerned. Ayat (3) provides that the P2K3 is confirmed by the Minister or an appointed official on the proposal of the employer or pengurus. The widespread practice of seating the site's top manager as Chairman follows from the employer-element requirement rather than from an express clause naming the Ketua.
10How often must an enterprise submit its official P2K3 activity report to the local Dinas Tenaga Kerja / Kemnaker under Permenaker No. Per-04/MEN/1987?
A.Every month (monthly)
B.Every 3 months (quarterly)
C.Every 6 months (biannually)
D.Once every year (annually)
Explanation: Pasal 12 of Permenaker No. Per-04/MEN/1987 obliges the pengurus to report on P2K3 activities at least once every 3 months (laporan triwulan). The report is addressed to the Minister and submitted through the local manpower office, which in today's structure is the Disnaker of the district or city.

Ahli K3 Umum (AK3U): Suggested Study Strategy

1Memorize statutory thresholds under Permenaker 02/1992: workplaces with >100 workers, or <100 with high-risk installations, require a designated Ahli K3.
2Distinguish between the Sertifikat Calon Ahli K3 Umum (issued to the individual) and the SKP / Lisensi Kewenangan (issued to the individual at a specific employing company, valid for 3 years).
3Master accident statistics formulas: Frequency Rate (FR = accidents × 1,000,000 / exposure hours) and Severity Rate (SR = lost workdays × 1,000,000 / exposure hours).
4Learn specific Kemnaker technical regulations: Permenaker 38/2016 for production machinery, Permenaker 8/2020 for lifting equipment, Permenaker 37/2016 for pressure vessels, Permenaker 12/2015 for electrical safety, Permenaker 04/1980 for APAR, Kepmenaker 187/1999 for hazardous chemicals, and Permenaker 5/2018 for work environment exposure limits (NAB).
5Learn the inspection and testing intervals side by side, because they differ per regulation: Pesawat Tenaga dan Produksi at 1 year and 5 years, Pesawat Angkat dan Angkut at 2 years for the first periodic riksa uji then annually, Tangki Timbun at 2 years and 5 years, land steam boilers at 2 years, and lightning protection at 2 years.

Frequently Asked Questions

What is the statutory basis for appointing an Ahli K3 Umum in Indonesia?

Appointment is governed by Permenaker No. Per-02/MEN/1992 in execution of Undang-Undang No. 1 Tahun 1970. Under Pasal 2, an employer must appoint an Ahli K3 if the workplace employs more than 100 workers, or employs fewer than 100 workers but carries high risk due to hazardous materials, hazardous plant installations, or explosion and fire dangers.

Which authority issues the Ahli K3 Umum credential and what documents are received?

The credential is issued by Kementerian Ketenagakerjaan (Kemnaker) through the Direktur Jenderal Pembinaan Pengawasan Ketenagakerjaan dan K3. Successful candidates receive three documents: a Sertifikat Calon Ahli K3 Umum, a Surat Keputusan Penunjukan (SKP) Ahli K3 Umum, and a Lisensi Kewenangan (Kartu Kewenangan) Ahli K3. The SKP and lisensi are valid for 3 years and are renewable through Kemnaker's TemanK3 portal.

How is the Ahli K3 Umum training and examination structured?

Kepmenakertrans No. KEP.239/MEN/2003 set the base: at least 120 jam pelajaran of 45 minutes across five material blocks, with pass or fail decided on a written exam set by a Kemnaker evaluation team. Kepdirjen Binwasnaker & K3 No. 5/94/HK.03.01/V/2026, which providers report replaced the 2015 pedoman from 20 May 2026, keeps the 120 JP over 12 days at a maximum of 10 JP per day and adds three delivery modes — face-to-face, online, and blended. The assessment is a K3 inspection practice with a written report, a seminar, and a written theory exam sat in person through the TemanK3 system, and the certificate, SKP, and Kartu Kewenangan are issued digitally through the same system.

What is the fee for the Ahli K3 Umum examination and training?

There is no fixed statutory government fee. Licensed PJK3 training providers set their commercial fees independently based on delivery format (online, blended, or offline residential), typically ranging between Rp 4,500,000 and Rp 8,500,000. Candidates should verify the fee and inclusions directly with their chosen Kemnaker-registered PJK3.

Are these practice questions an official Kemnaker examination?

No. They are independent English-language multiple-choice practice by OpenExamPrep covering the statutory and technical OSH knowledge the programme teaches. The official assessment is conducted in Indonesian and includes a written theory exam sat in person through TemanK3 plus a K3 inspection practice report and a seminar, which multiple-choice practice cannot reproduce.
