Abstract

Kemiri Sunan (Reutealis trisperma) presents numerous advantages over other biofuel-producing plants due to its straightforward processing and high oil yields. This makes it a viable solution for reducing fossil fuel consumption by producing sustainable biofuels. This study aims to explore the potential of Kemiri Sunan (Reutealis trisperma) as a sustainable source of biofuel to reduce fossil fuel consumption. The study employed a bioprocessing method that includes oil extraction and bioprocessing of solid waste into soil enhancers through enzymatic composting fermentation. The results indicate that Kemiri Sunan produces high yields of enzymatically hydrolyzed oil suitable for biofuel production and offers sustainable energy output for up to 50 years. In addition, the solid waste generated during processing can be effectively utilized to enhance soil quality, contributing to sustainable organic fertilizer production. In conclusion, Kemiri Sunan is a promising candidate for bioenergy due to its efficient oil production, minimal environmental impact, and simplified policy framework, as it avoids the food-energy conflicts associated with crops like palm oil. Its cultivation of degraded land ensures sustainability, making it a valuable future resource for green energy.
