- ABSTRACT Esterification of fatty acids from palm oil waste.(sludge oil) as biodieselliquid base has been done by using alum {AllfS04h 14H20] catalyst. Some reaction variables like reaction time, catalyst quantity, and molar ratio of sample-reactant was applied for optimal reaction. Yield of 94.66% was obtained at reaction condition 65 GC, 5 h, sample-reactant ratio 1:20, and catalyst quantity 3% (w/w). GC-MS analysis request showed that composition of methyl esters biodiesel are methyl caproic (0.67%), methyl lauric (0.21%), methyl miristic (1.96%), methyl palmitic (49.52%), methyl oleic (41.51%), and methyl stearic (6.13%). Physical properties of synthesized product (viscosity, .refraction index and density) are similar with those of commercial product. Keywords: alum, biodiesel, esterification, sludge oil
