Abstract: Abundant of waste animal bones can be found especially in restaurant and wet market. In fact, waste animal bones contributed to huge number of our daily municipal waste. Most of these wastes are being thrown away without any proper treatment of disposal. Animal bones contain a good amount of CaO to be used as a catalyst for transesterification process. In this study, transesterification of Waste Frying Oil (WFO) with waste chicken bones as catalyst were studied. The effect of reaction condition such as reaction temperature, reaction time, molar ratio of methanol and oil and also catalyst concentration towards product yield were investigated. From the analysis results for the catalyst using XRD, SEM and FTIR, it shows that the waste chicken bones contain CaO that can be used as the catalyst for the transesterification process. For the effect of parameter studied, the result shows the yield of biodiesel increased with the increase of reaction temperature and the highest yield of 87.68% was obtained at reaction time of 3 h, reaction temperature of 60°C, catalyst concentration of 15% and molar ratio of methanol and oil is 6:1. From the chromatography peaks, it shows that the biodiesel consist of Methyl Laurate (C12:0), Methyl Myristate (C14:0), Methyl Palmitate (C16:0) and Methyl Palmitelaidate (C16:1). The highest compound contain in the product is Methyl Laurate (C12:0) with 56.54%.
