Jakarta (ANTARA) – Indonesia will implement B50 biodiesel starting July 1 after nearly six months of trials showed positive results, Energy Minister Bahlil Lahadalia said on Monday.The B50 blend consists of 50 percent crude palm oil (CPO) and 50 percent fossil diesel, and has been tested across multiple sectors, including heavy equipment, ships, trains and trucks.“It will be finalized soon, and implementation will begin on July 1,” Lahadalia said, adding that the policy is expected to strengthen energy security by reducing reliance on imported fuels and expanding the use of domestic renewable resources.According to Lahadalia, recent geopolitical tensions in the Middle East highlight the risks faced by countries heavily dependent on imported energy.“Without diversification, our energy security would be vulnerable. We must rely on our own resources,” he said.Indonesia currently enforces a B40 mandate, which blends 40 percent palm-based biodiesel with 60 percent petroleum diesel.The B40 program has reduced diesel imports by 3.3 million kiloliters (kL) and cut carbon emissions by 38.88 million tonnes of CO2 equivalent, the minister said.Government data show biodiesel utilization reached 14.2 million kL in 2025, or 105.2 percent of the target of 13.5 million kL.The planned shift to B50 is part of President Prabowo Subianto’s strategy to strengthen resilience against global supply disruptions.The government estimates the policy could reduce fossil fuel consumption by about 4 million kL annually.It is also expected to save up to Rp48 trillion (US$2.81 billion) in subsidies, Coordinating Economic Minister Airlangga Hartarto said earlier.State energy firm PT Pertamina has expressed readiness to support the rollout, including supply and distribution.Indonesia, the world’s largest palm oil producer, has expanded biodiesel use over the past decade to curb fuel imports and stabilize domestic palm oil demand.Officials say the B50 rollout will be implemented gradually to ensure supply stability and technical readiness across sectors.Further evaluations will be conducted during the initial phase to monitor performance and address potential operational challenges.
