Indonesia is set to significantly expand its bioethanol production as part of its broader strategy to reduce reliance on imported fossil fuels and promote sustainable energy solutions. According to reports, the country aims to produce 4 million kiloliters of ethanol annually to meet the requirements of the E20 biofuel blend, which mandates that 20% of conventional gasoline be replaced with bioethanol. This ambitious target underscores the government's commitment to transitioning towards cleaner, more domestically sourced energy alternatives.
At the heart of this initiative is the exploration of alternative feedstocks for bioethanol production, with particular emphasis on sugar palm (aren). The National Research and Innovation Agency (BRIN) has highlighted the potential of sugar palm as a sustainable and efficient source of bioethanol. Researchers at BRIN’s Biomass and Bioproducts Research Center, led by Saptadi Darmawan, have pointed out that sugar palm sap is an ideal raw material due to its high sucrose content and ease of processing. Unlike other bioethanol sources such as starch or wood biomass, which require complex industrial processes, sugar palm-based bioethanol can be produced through simple fermentation and distillation methods.
One of the most compelling advantages of using sugar palm for bioethanol is its superior performance characteristics. The resulting bioethanol has an octane rating of approximately 108, surpassing the octane level of standard high-octane gasoline. This makes it particularly suitable for blending into existing fuel systems without requiring significant modifications. Additionally, sugar palms have a long lifespan, producing sap for up to 20 years, which enhances their sustainability credentials. They can also be cultivated on marginal or underutilized lands, thus avoiding competition with food crops and contributing to both environmental conservation and rural livelihoods.
Despite these benefits, the development of sugar palm-based bioethanol is not without challenges. One major concern is the potential conflict between the use of sugar palm for food and energy purposes. In certain regions, sugar palm sap is already used in the production of traditional alcoholic beverages, which command higher market prices. To address this issue, Darmawan suggests creating distinct zones for sugar palm cultivation—dedicated to either food or energy production—to prevent resource conflicts and ensure smooth development.
Economically, the sugar palm bioethanol industry appears promising. Preliminary studies indicate that the cost of production ranges from Rp8,500 to Rp10,000 (approximately US$0.56) per liter, while the selling price is projected to be between Rp14,000 and Rp16,000 (about US$0.90) per liter. This results in a gross profit margin of 35 to 45%, making the venture attractive for cooperatives and small-scale producers. However, the current state of sugar palm plantations presents a challenge. According to data from the Indonesian Statistical Office (BPS), the total area dedicated to sugar palm cultivation has declined slightly over the past few years, from 64,544 hectares in 2019 to 60,557 hectares in 2023. Production figures have similarly seen a slight decrease, dropping from a peak of 107,415 tons in 2021 to 100,273 tons in 2023.
To advance the development of sugar palm-based bioethanol, the Forestry Ministry has taken a tangible step by launching a pilot project at the Pertamina Geothermal Energy (PGE) Kamojang facility in Garut, West Java. This project, which began operations in December 2025, uses sugar palm sap supplied by the Baru Bojong Social Forestry Business Group (KUPS). With a daily production capacity of approximately 300 liters of bioethanol from 300 to 500 kilograms of sap, the pilot serves as a crucial test case for scaling up the technology. Officials estimate that one hectare of sugar palm plantation could yield about 24,000 liters of bioethanol annually, highlighting the plant's potential to contribute meaningfully to national energy security.
Looking ahead, the success of the sugar palm bioethanol initiative will depend on addressing ongoing challenges, including improving raw material quality standards, resolving land-use conflicts, and expanding plantation areas. As Indonesia continues to push forward with its E20 and B50 fuel blends, the role of sugar palm in the nation's energy transition remains a focal point for researchers, policymakers, and industry stakeholders alike.
