Abstract: The use of heterogeneous catalysts in the production of biodiesel provides many advantages due to heterogeneous catalysts can be easily separated from the product so that it can be reused. This research using heterogeneous catalysts derived from natural materials, namely banana stem ash and coal fly ash containing alkali and alkaline earth elements. The preparation of catalyst from banana stem ash and coal fly ash used activator KOH 1.9 N and impregnation with KNO3 15 % and then heated to a temperature of 550 0C for 3 hours. Results of preparation, banana stem ash contains potassium of 36.52 % and surface area of 41.901 m2/g. This work presents the effect of ultrasonic assisted of waste cooking oil with methanol as solvent using banana stem ash and coal fly ash as catalyst. The diameter of catalyst particles of banana stem ash and coal fly ash varied at 50, 100, 150, 200 and 250 mesh. The transesterification reaction was performed in the presence of ultrasonic operating frequency constant at 40 kHz, methanol molar ratio to oil of 9 : 1 and reaction time of 30 minutes. The methyl ester (biodiesel) content of product was 93.26 % of banana stems ash and 57 % of coal fly ash respectively. The physical property was compared with the National Indonesia Standard (SNI) 2006 with a density, viscosity, cloud point, flash point and cetane number.
