Transesterification of used cooking oils with methanol was produce methyl esters (biodiesel) by using CaO as catalyst dissolved by KOH. The CaO obtained from the shelled chicken shells mixed with KOH with variations of % K (0 %, 5 %, 7%, 9 % and 12 %) is accompanied by heating at 85 0C, while the catalytic properties are performed by XRD, Base and SEM.-EDX. The catalysts obtained are then used for the biodiesel production, the best biodiesel yields by producing 87.17% in catalysts of 7% K and oils : methanol (1:12) moles ratio, 1.5 % total oil catalysts, reaction time of 2, 5 hours, the reaction is 65 0C, biodiesel characteristics, kinematic viscosity of 2.89 cSt, 0.032 % water content, density 0.819 g / ml, methyl ester content 99.39 %.
