Kemiri Sunan ( Reutealis trisperma ) has great potential as a source of raw material for biodiesel production due to its high oil content. The oil is a non-edible oil that can be extracted using screw-press machine. In this study, a descriptive research with regression and correlation analysis was used to investigate the effect of feed material level on pressing performance and kemiri sunan’s oil quality. A variation of the feed material level (2, 4, 6, 8, and 10 kg) was fed into screw-press machine. The results showed that cylinder temperature and pressing time increased as the feed material level increased. The highest production (2.87 kg / hour) and yield (37.33%) capacity were obtained at 4 kg of the feed material level. Hence, increasing the feed material level did not affect the quality of the oil produced. Density, acid number, Free Fatty Acid (FFA), saponification number, kinematic viscosity and refractive index of oil produced ranged between 919.48-924.76 kg/m 2 , 30.82-47.79 mg KOH/g oil, 15.25-23.65%, 154.64 -186.84 mg KOH/g oil, 45.59-56.34 mm 2 /s and 0.00328-00.332 respectively.
