The growing demand for petroleum in Indonesia, driven by increasing energy needs, is depleting the country's petroleum reserves. As a result, alternative energy sources such as bio-oil are necessary through pyrolysis process. In this study, the physical and chemical characteristic of bio oil from the mixture of sawdust (SD) and oil palm empty fruit bunches (OPEFB) are investigated. The highest bio-oil yield was obtained from the feed with 100% OPEFB at 600 °C with the yield of 37.33%. The pyrolysis process was conducted in a pyrolysis reactor with the N2 flowrate of 3 L/min and 1 hour residence time. The results showed that the highest bio-oil was obtained from the biomass waste of 100% OPEFB at 600 °C with a bio-oil yield of 37.33%, a calorific value of 6697.94 cal/g and a density of 0.964 g/mL. © 2026 American Institute of Physics Inc..
