..business entities are currently improving B50 specifications,\nparticularly the FAME (Fatty Acid Methyl Ester) component blended with\ndiesel fuel supplied by Pertamina Patra Niaga,Yogyakarta (ANTARA) - The\nEnergy and Mineral Resources (ESDM) Ministry has begun testing the use\nof B50 fuel in train diesel engines, including trials at the Lempuyangan\nRailway Supervisory Unit (PUK) in Yogyakarta.<\/p>\n
\u201cThe railway sector is undergoing two tests. From Lempuyangan to\nJakarta, we\u2019re testing the generators. As you can see, the generators\nwill run for 2,400 hours,\u201d said Eniya Alistiani Dewi at the Lempuyangan\nPUK in Yogyakarta on Monday.<\/p>\n
She explained that B50 is a blend of 50 percent diesel fuel and 50\npercent biodiesel. Additional tests are also being conducted on\nlocomotives operating on the Surabaya\u2013Jakarta route over a six-month\nperiod.<\/p>\n
\u201cThe final test phase for B50 use on railways will take place in\nOctober 2026. We\u2019re conducting tests under real-world conditions to\nevaluate the results,\u201d she said.<\/p>\n
Dewi noted that B50 utilization tests have been underway since last\nyear in preparation for its planned implementation on July 1, 2026. Road\ntests under real-world conditions began on December 9, 2025, following a\nseries of technical laboratory assessments.<\/p>\n
\u201cSince December 9, we have carried out a full series of\nimplementation tests across the automotive, mining, agricultural\nequipment, shipping, and generator sectors. Most recently, we began\nrailway tests after Eid al-Fitr. This is the first time we\u2019re testing\nB50 on trains,\u201d she said.<\/p>\n
She added that the B50 program has been in development for 15 years\nand is unique to Indonesia, which currently leads the world in its\nimplementation. According to Dewi, other countries are looking to\nIndonesia as a reference for B50 adoption, as there are few global\nprecedents.<\/p>\n
Therefore, she emphasized that the current testing phase is critical\nand must be carried out now. She expressed hope that the trials will\nproceed smoothly and allow the public to observe the process.<\/p>\n
\u201cIt\u2019s important to note that business entities are currently\nimproving B50 specifications, particularly the FAME (Fatty Acid Methyl\nEster) component blended with diesel fuel supplied by Pertamina Patra\nNiaga,\u201d she said.<\/p>\n
Meanwhile, Heru Kuswanto from PT Kereta Api Indonesia expressed\nappreciation to all parties involved in implementing B50 trials in the\nrailway sector.<\/p>\n
\u201cThe main objective of B50 biodiesel\u2014a blend of 50 percent palm oil\nand 50 percent diesel\u2014is to strengthen national energy security and\npromote more sustainable green energy,\u201d he said.<\/p>\n
He added that the strategic benefits of the B50 program include\nsupporting energy independence, reducing carbon emissions, enhancing\neconomic resilience, diversifying energy sources, and optimizing\ndomestic resources.<\/p>\n
PT KAI is supporting the implementation of B50 through trials on the\nBogowonto train. The company will collaborate with the ESDM Ministry and\nLemigas to evaluate the performance of locomotive engines and generator\nsets under heavy loads using both B50 and B30 fuels.<\/p>\n
