JAKARTA - The Ministry of Energy and Mineral Resources (ESDM) conducted a test of the use of B50 in the railway sector which took place in Yogyakarta. This step is an important part of the series of preparations for the implementation of B50 nationally in early July 2026, as well as ensuring technical readiness in the strategic transportation sector.
Director General of New and Renewable Energy and Energy Conservation (EBTKE) Eniya Listiani Dew said that the trial of the implementation of B50 had been carried out since December 2025, and the railway sector started the latest.
"So since December 9 (2025) we have started the entire series of implementation tests in automotive, mining, agricultural tools, tests in shipping, tests in gensets and finally tests in railways, because we have to wait for Eid to be completed," he said, Monday, April 27.
Eniya said that the B50 trial for the train would be carried out in two tests, the first at Lempuyangan Station was for testing the train's generator that would depart for Jakarta and return to Yogyakarta for 2,400 hours. The other test is for the locomotive in Surabaya which will be carried out for six months.
For the results of the B50 test on this train, Eniya hopes that the results will be as good as the B50 trial in the automotive sector, and will wait for a detailed report from PT KAI on the condition of the filter and when to replace the filter.
"So the railway, the train engine is slow, the category is a low speed engine, if the automotive is the highest speed engine. Well, it can be confirmed that it will definitely work for the train. Well, we'll see what the filter is like in this railway," he added.
On the same occasion, Director of Facilities Management of PT KAI (Persero), Heru Kuswanto, said that PT KAI fully supports the B50 floating trial in the transportation sector, because its main objective is to strengthen national energy resilience and sustainable use of green energy. However, it must still pay attention to safety, security, and continuous technical evaluation to maintain the reliability of the facilities.
"We hope that this activity can run smoothly and provide optimal benefits, not only for the development of railway technology, but also this sector supports the energy transition, towards a more environmentally friendly and sustainable transportation system," he said.
