N2  - The study investigates the viability of Calophyllum inophyllum (Bitaog) seeds  as a biodiesel feedstock, focusing on the comparative efficiency of raw versus matured  seeds. This research addresses the critical need for alternative biodiesel sources,  considering the drawbacks associated with edible oil-based biodiesel, such as food  supply depletion and economic imbalances. The purpose of this study is to evaluate the  oil yield and quality of Bitaog seeds and determine the most efficient extraction method  for potential biodiesel production. The research employed mechanical and chemical  extraction techniques on both raw and matured Bitaog seeds. Mechanical pressing was  performed at controlled temperatures (160°C, 180°C, and 200°C) while chemical  extraction utilized a Soxhlet apparatus with acetone as the solvent. Oil yield, density,  viscosity, absorbance, pH value and acid value were assessed in this study. Results  indicated that there is no difference in oil yield with varying temperatures of both raw  and matured under mechanical extraction methods while chemical extraction has a low  oil yield of both raw and matured. Furthermore, the oil extracted displayed physical  and chemical properties, aligned with biodiesel standards. The study concludes that  Bitaog seeds are a promising feedstock for biodiesel production, offering a sustainable  alternative to edible oil sources. The findings suggest that adopting advanced extraction  technologies such as oil extraction can improve oil recovery and quality, enhancing the  economic viability of Bitaog-based biodiesel. Recommendations for future research  include exploring large-scale applications and optimizing extraction processes to  further increase efficiency and reduce costs
