Synthesis of biodiesel from the beef tallow using catalyst from Psammotaea elongata shell with methanol as a solvent was carried out. Synthesis the biodiesel was prepared in two steps, there are esterification and transesterification. In esterification was conducted in mole ratio of oil and methanol were 1: 9, with H2SO4 as a catalyst. Transesterification process conducted with mole ratio were 1:12 (oil and methanol), with CaO from cockle’ shell as a catalyst with a variation of the catalyst 11%, 12%, 13%, and 14%. Result of biodiesel was characterized based on FT-IR, 1H-NMR, GC-MS, and ASTM (American Standard Testing of Materials) method. The results obtained by the catalyst conversion of 51.9% and the optimum conditions in the biodiesel present in 12%. Yielded of biodiesel theoretically was 59.118% and experiment was 18.34%. The main component on biodiesel product is methyl stearate (40.65%) and examination result of biodiesel by using ASTM method are specific (0.8695 g/cm3), kinematic viscosity (5.393 mm/s2), flame point (178.5 °C), pour point (24 °C), and carbon Condradson residue (0.071%).
