Ten provinces across the island of Sumatra
PT Rindu Tenang Indonesia prepares OHS competency for industry throughout Sumatra, from Aceh to Lampung. Programmes follow the work processes, shift patterns, and hazards that exist at your location, rather than a single general syllabus applied to every plant.
Sumatra is not a single uniform market. Refineries and oil fields in Riau call for confined space competency and H2S readiness; palm oil mills in North Sumatra and Riau deal with steam equipment and boilers; container terminals at Belawan and Batam need lifting equipment operators and riggers; mines in South Sumatra and Bangka Belitung follow a different competency route again. Programmes are built per location because the hazards are different per location.
The industrial estate names and areas below follow the register kept by the Ministry of Industry. Provinces with no registered estate are still served, since their industry sits outside the formal estates.
Medan
The largest industrial estate area in Sumatra, alongside the Port of Belawan and a cluster of palm oil mills.
Tanjung Pinang
Twenty registered industrial estates, the highest count in Sumatra, concentrated in Batam and Bintan.
Pekanbaru
A centre for oil and gas and downstream palm processing, where confined space and hot work competency stand out.
Palembang
A coal mining cluster that follows its own competency route under mining sector supervision.
Pangkal Pinang
Tin and mineral processing, carrying smelting and hot material handling hazards.
Padang
Cement production and the Teluk Bayur port drive most of the competency demand here.
Banda Aceh
Only one registered estate so far; most demand sits with energy operations and ports.
Bandar Lampung
The land gateway to Sumatra, with agro-industry and the Bakauheni ferry port.
Jambi
No registered industrial estate yet; demand centres on palm oil mills and oil and gas operations outside the formal estates.
Bengkulu
No registered industrial estate yet; demand centres on coal mines and palm oil mills.
Each sector has its own page covering the programme detail, the certification route, and the questions that come up most often.

Proof of OHS competence in Indonesia does not come from a single door. Three official routes exist, each with its own legal basis, and they stand on their own — they are not tiers, they do not replace one another, and holding one does not confer the others. Working out which one is actually being asked for is the first step, before any budget is committed.
Ministry of Manpower
The obligation comes from labour law — Act No. 1 of 1970 and the ministerial regulations beneath it. This is the route a labour inspector checks on a site visit, and for roles such as lifting-equipment operator or OHS electrical technician, nothing else can stand in its place.
National Professional Certification Agency
It rests on the SKKNI national competency standards, and the certificate is issued by a Professional Certification Body (LSP) holding a BNSP licence — not by BNSP itself, and not by the training provider. This is the route usually asked for at tender prequalification and in customer audits.
National Accreditation Committee & International Accreditation Forum
This layer assesses the institution, not the candidate. KAN accredits certification bodies in Indonesia, and KAN's membership of the IAF Multilateral Recognition Arrangement is what makes that accreditation recognised abroad. The companies that benefit are those whose certificates must be accepted by an overseas client or principal.
All three stand on their own. Holding a BNSP certificate does not discharge a Kemnaker licensing obligation, and KAN accreditation replaces neither. PT Rindu Tenang Indonesia issues none of them — RTI runs the preparatory training and arranges the competency assessment, while the proof itself is issued by the authorised body. Mapping which one your site is actually being asked for comes first, and costs nothing at that stage.
Industrial estate names and areas follow the register kept by the Ministry of Industry. Every figure on this page can be traced to its source, and none of them assert a market ranking.
