Cement clinker used as solid base catalyst and activated through calcination method. Effect of calcination temperature on the catalytic performance studied. The catalyst with the highest activity is obtained when the calcination temperature of 800 °C and the calcination time of 7 hours with transesterification reaction conditions are a molar ratio of methanol/oil 6:1, catalyst dosage of 3% by weight, temperature of 70 °C for 2 hours with yield biodiesel results reached 76,84%. CaO, SiO2, 2CaO.SiO2 and 3CaO.SiO2 materials found in the catalyst through x-ray diffraction (XRD) analysis and specific surface area of catalyst is 35,879 m2/g through Brunauer-Emmett-Teller (BET) analysis. Main composition of biodiesel found through Gas Chromatography-Mass Spectrometry (GC-MS) analysis, such as methyl palmitate, methyl oleate, methyl stearic, methyl myristate, methyl arachidate and methyl laurate.Keywords: biodiesel, calcium oxide, catalysts, cement clinker, transesterification.
