Abstrakt: As global energy demands rise and non-renewable resources decrease, identifying sustainable alternatives is of utmost importance. This study investigates the potential of Carica papaya seeds as a feedstock for bio-oil production. Employing the central composite design of response surface methodology, the extraction process was optimized using heptane as the solvent. The effects of biomass to heptane ratio and extraction time on oil yield were examined. The optimized conditions of 1:11 biomass to heptane ratio (g:mL) and 4-h extraction time yielded an optimal oil yield of 45.77±0.057%. The chemical composition analysis revealed a kinematic viscosity of 12.58 mm2/s at 40°C, indicating favorable flow properties, and a high heating value of 37.52 MJ/kg, suggesting its energy potential. Fourier transform infrared (FTIR) analysis detected carbonyl functional groups and alkanes, indicating the suitability of Carica papaya seed oil for biodiesel production. These findings highlight the promising role of Carica papaya seeds as a renewable feedstock for bio-oil, contributing to sustainable energy development. This research addresses the pressing challenge of depleting non-renewable resources and underscores the significance of Carica papaya seeds as a valuable and eco-friendly source for bio-oil production. Such advancements pave the way for a greener and more sustainable energy future. [ABSTRACT FROM AUTHOR]
