President Prabowo Subianto Orders Ministry of ESDM to Develop E50 Bioethanol Fuel to Curtail National Gasoline Imports

Jakarta, Indonesia — In a decisive push toward bolstering national energy independence and insulating the domestic economy from volatile global crude oil markets, President Prabowo Subianto has officially directed the Ministry of Energy and Mineral Resources (ESDM) to formulate a comprehensive framework for the development and implementation of a 50 percent bioethanol fuel blend, widely designated as E50.

The high-level directive was formally issued during the inaugural Plenary Session of the National Energy Council (Dewan Energi Nasional or DEN) for the year 2026, convened at the historic Merdeka Palace in Jakarta. The strategic mandate represents a monumental escalation of Indonesia’s green energy transition, mirroring the ambitious trajectory previously established for the nation’s heavily publicized biodiesel sector.

Minister of ESDM Bahlil Lahadalia, speaking to reporters following the high-stakes closed-door meeting, emphasized that the blueprint for E50 draws direct operational and structural lessons from the successful rollout of the B50 program—a mandatory 50 percent palm oil-based biodiesel blend implemented for diesel engines nationwide beginning July 1, 2026.

"Building upon the foundation and operational insights gained from that program, the President has explicitly instructed us to immediately draft identical strategic steps to develop and deploy E50," Bahlil stated.

The push for E50 is not merely an environmental aspiration; it is an aggressive economic intervention designed to structurally alter Indonesia’s energy trade deficit. According to official figures cited by the Ministry of ESDM, Indonesia’s national consumption patterns for diesel and gasoline run neck-and-neck. The annual domestic demand for diesel hovers around 39 million kiloliters, while gasoline consumption mirrors that massive volume closely, ranging between 39 million and 40 million kiloliters annually.

Minister Bahlil asserted that the aggressive implementation of the B50 mandate has effectively eradicated the necessity of importing CN 48 diesel fuel, successfully shifting domestic reliance entirely to homegrown biodiesel feedstocks. Armed with this precedent, the government is now engineering a parallel framework for gasoline through the E50 scheme, capitalizing on the reality that gasoline consumption volumes are virtually identical to those of diesel.

While the ultimate goal of E50 is to drastically slash costly fossil fuel imports and strengthen the national trade balance, Minister Bahlil stopped short of providing a definitive, hard timeline for the full commercial rollout of the 50 percent blend, noting that technical, logistical, and agricultural preparations must first be meticulously ironed out.

The Chronology and Regulatory Roadmap of Bioethanol Integration

The journey toward a high-percentage bioethanol blend in Indonesia has been methodical, governed by a series of progressive regulatory milestones rather than abrupt market disruptions. Up to the present juncture, the blending of bioethanol into conventional motor gasoline has not operated as a mandatory nationwide policy, leaving commercial initiatives to test the waters of consumer acceptance.

To date, the sole prominent market offering is Pertamax Green 95, a commercial grade of fuel blended with 5 percent bioethanol (E5), which is retailed to motorists through select stations operated by state-owned energy giant PT Pertamina Patra Niaga.

The legal foundation steering the nation’s biofuel integration was formally solidified with the issuance of Ministerial Decree of ESDM Number 113.K/EK.05/MEM.E/2026. Promulgated on March 3, 2026, the decree outlines a rigid, phased timeline for the mandatory utilization of plant-based fuels across the archipelago.

Under the provisions of this regulatory roadmap, the mandatory implementation of the E5 blend is scheduled to run its course across the domestic market through 2027. Following this foundational phase, the mandate is legally mandated to step up to a 10 percent bioethanol blend (E10) spanning the 2028 to 2030 window.

However, regulatory ambitions have recently accelerated to outpace the baseline calendar. Aside from the official multi-year phasing decree, the Ministry of ESDM has advanced aggressive targets within internal policymaking circles. During a working meeting with Commission XII of the House of Representatives (DPR RI) on September 8, 2026, Eniya Listiyani Dewi, the Director General of New, Renewable Energy and Energy Conservation (EBTKE), revealed that the government is aggressively targeting the rollout of an E20 mandate—a 20 percent bioethanol blend—by the year 2028.

The newly minted directive by President Prabowo to study and build the framework for E50 effectively telescopes these long-term renewable goals, establishing a super-target that will require unprecedented synchronization between agricultural feedstock producers, chemical refiners, and fuel distributors.

Bolstering National Energy Security Amid Global Geopolitical Friction

Beyond the specific mechanics of fuel blending, the inaugural 2026 plenary session of the National Energy Council placed heavy emphasis on national vulnerability in the face of escalating global geopolitical tensions. With supply chains susceptible to disruptions stemming from conflicts in key energy-producing regions and fluctuating maritime trade routes, maintaining robust domestic buffer stocks has emerged as a paramount security priority for the Prabowo administration.

Current government assessments indicate that Indonesia’s strategic national BBM (fuel oil) reserve stock hovers between 18 and 20 days of operational coverage. During the Merdeka Palace meeting, President Prabowo issued a strict directive mandating that this buffer capacity must be fiercely protected, ensuring that national reserves never dip below the critical threshold of 18 to 20 days under any foreseeable domestic or international shock.

Minister Bahlil framed the accelerated push toward E50 not merely as a climate-conscious decarbonization strategy, but fundamentally as an indispensable pillar of national defense and economic sovereignty. By substituting imported crude components and refined gasoline with domestically produced bioethanol—largely derived from sugarcane, cassava, or other sustainable agricultural starches—Indonesia can insulate its fiscal reserves from foreign exchange pressures and external supply shocks.

"This initiative serves as a core mechanism to fundamentally reinforce the availability and resilience of our domestic fuel supply," Bahlil emphasized.

Broader Economic, Agricultural, and Industrial Implications

The transition toward high-blend bioethanol fuels such as E20 and the newly conceptualized E50 carries profound, far-reaching implications for multiple sectors of the Indonesian economy, extending far beyond the petroleum refineries and gas stations.

First, the agricultural sector stands to undergo a massive transformation. To sustain a nationwide E50 supply chain, Indonesia will require a gargantuan, uninterrupted supply of bioethanol feedstock. This necessitates a massive revitalization and expansion of domestic agricultural productivity—particularly in commodities like sugarcane and cassava. Agronomists and industry analysts note that this demand could trigger substantial investments in rural infrastructure, drive land-use optimization, and provide millions of smallholder farmers with guaranteed, high-volume industrial off-takers. However, policymakers will face the delicate challenge of balancing food security against energy feedstock cultivation to prevent arable land competition from driving up staple food prices.

Second, the automotive and industrial manufacturing sectors will need to adapt. While modern vehicle engines are increasingly tolerant of low-blend biofuels like E5 or E10, higher concentrations such as E20 and E50 can present technical challenges regarding material compatibility, fuel system corrosion, and engine calibration. Automotive manufacturers operating in Indonesia will likely need to test, certify, and potentially modify vehicle fuel systems to ensure long-term durability and performance when running on ultra-high ethanol blends.

Finally, the macroeconomic ramifications for Indonesia’s current account balance cannot be overstated. For decades, fossil fuel imports have been a persistent drain on the nation’s foreign exchange reserves, heavily exposing the Indonesian rupiah to shifts in global crude oil prices. By systematically replacing tens of millions of kiloliters of imported gasoline with domestically grown and processed bioethanol—much in the same vein as the triumphant B50 biodiesel rollout—Indonesia edges closer to genuine energy self-sufficiency.

As the Ministry of ESDM spearheads the formulation of the E50 framework over the coming months, all eyes will be on regulatory clarity, feedstock scalability, and industrial readiness. President Prabowo’s directive signals a clear, unyielding trajectory: Indonesia is aggressively engineering its energy future away from foreign dependence and toward homegrown, renewable sovereignty.
