For three years, Ardhyananta and his colleagues at the Institut Teknologi Sepuluh Nopember labored to bridge the gap between Indonesia’s vast agricultural wealth and its energy needs. While the nation had already integrated palm oil into diesel, the gasoline engines that power the country’s countless small-scale farm machines and motorbikes remained tethered to fossil fuels. The technical hurdle was the catalyst—the chemical "key" required to unlock the energy within the palm oil’s triglycerides.
Where industrial refineries often rely on precious metals like platinum—costing nearly a thousand dollars an ounce—Ardhyananta’s team turned to a more humble combination: nickel and copper oxides. This bimetallic catalyst allowed the team to lower the reaction temperature to 380°C, a efficiency gain that makes the process viable outside of massive industrial complexes. The result is "Benwit," a biogasoline with a RON 90 rating, matching the standard fuel used across the Indonesian archipelago.
The significance of this discovery is felt most keenly at the edge of the field. By deploying Benwit in agricultural machinery, Ardhyananta has seen farmers move toward a quiet independence. They are no longer solely at the mercy of the fluctuating prices of the global oil market; instead, they can look to the trees surrounding their own villages for the power to harvest them. The process even accounts for its own waste: the liquid residue left behind after the gasoline is extracted is recycled as fuel for cooking stoves.
As the Directorate of Research and Community Service prepares to pilot the project on a national scale, the vision is one of circularity. Indonesia produces over 50 million tonnes of palm oil every year, much of it shipped across oceans. If even a tenth of this harvest stays home to be refined through Ardhyananta’s catalysts, the country could see a 10% reduction in its total national fuel consumption, powered by the very soil it cultivates.
