%X This research aims to determine the comparison of biodiesel yield from palm oil using K2O/zeolite and K2O/activated carbon catalysts. Synthesis of K2O/zeolite and K2O/activated carbon catalysts were carried out through a KOH impregnation process. XRD test results of K2O/zeolite and K2O/activated carbon catalysts show that the K2O peak is successfully formed at corner 2θ:29,6°; 32,2°; 39,7°; and 48.6°. The transesterification reaction was carried out at a temperature of 60°C for 2 hours with a mole ratio of oil and methanol of 1:6 and the addition of 3% catalyst. Biodiesel with K2O/zeolite catalyst produced a yield of 51,66% and biodiesel with K2O/activated carbon catalyst produced a yield of 78,53%. The higher yield of K2O/activated carbon biodiesel is due to the fact that the K2O/activated carbon catalyst has more K2O compounds. Based on the GC-MS test results, biodiesel with K2O/zeolite and K2O/activated carbon catalyst has a methyl ester composition of 99.6% and 100% respectively with the dominating methyl ester component, namely methyl ester palmitate. Flash point testing of biodiesel with K2O/zeolite catalyst and K2O/activated carbon catalyst show the respective results at a temperature of 150 °C and 145 °C.
