JAKARTA - PT Kereta Api Indonesia (Persero) ensures that all diesel facilities are ready to implement the use of biodiesel fuel B50 following the mandatory which applies since July 1, 2026.
"KAI's readiness is in line with the mandatory B50 biodiesel which the government has started to implement since July 1, 2026," said KAI Vice President of Corporate Communication Anne Purba confirmed in Jakarta, quoted by Antara, Thursday, July 2.
He conveyed that the readiness includes locomotives and generating trains which are an important part of diesel-based train travel operations.
Meanwhile, the Ministry of Energy and Mineral Resources (ESDM) conveyed the implementation of B50 accompanied by a transition period of three months as a room for adjustment in the field, including the management of old stocks and the process towards the full use of B50.
Anne said KAI supports the government's policy in strengthening the utilization of domestically sourced renewable energy. This support is carried out through the readiness of facilities, technical test runs, and strengthening the aspects of safety and reliability of operations.
"KAI supports the mandatory B50 biodiesel imposed by the government. In terms of facilities, all KAI diesel locomotives and facilities are ready to implement B50 after undergoing technical testing and strengthening operational safety aspects," said Anne.
He explained that the readiness was strengthened through a joint test with the Ministry of Energy and Mineral Resources on diesel-based railway facilities. The test was carried out to ensure the use of B50 in accordance with the characteristics of railway operations, both on locomotives and generating trains.
On the locomotive, the testing is directed to see the engine response when using B50 in the train travel operation pattern. Monitoring is carried out on engine performance, combustion stability, fuel consumption, and the condition of the main components so that the facility remains reliable when serving customer travel.
Meanwhile, on the power plant train, testing is carried out through inspection of generator performance, fuel consumption, emissions, filter conditions, and operational endurance.
This stage is important because the power train plays a role in maintaining electricity supply to support customer comfort during the journey.
"The use of B50 on railway facilities requires measurable technical readiness. Therefore, KAI conducts testing, monitoring, and evaluation so that its implementation remains in line with railway operation safety standards," he explained.
In terms of sustainability, the implementation of B50 strengthens KAI's contribution to the national energy transition agenda. The increase in the biodiesel mix helps increase the use of renewable energy in the country, reduce the use of fossil fuels, and support efforts to reduce emissions in the transportation sector.
KAI has also used biodiesel gradually in diesel facilities operations, ranging from B35 to B40. This experience is part of KAI's readiness to enter the B50 phase with a safe, measurable, and appropriate technical approach to operating needs.
"KAI is ready to carry out the use of B50 according to government directives. We have prepared all diesel facilities, so that this energy transition can run while maintaining travel safety, operational reliability, and quality of service to the community," he said.
