Abstract

The synthesis of biodiesel from the waste cooking oil was carried out using the catalyst from egg shell of purebred chicken with methanol as a solvent. Synthesis the biodiesel was prepared in two steps, there are esterification and transesterification. In esterification was conducted in mol ratio of methanol and waste cooking oil were 9:1, with H2SO4 as a catalyst. Transesterification with mol ratio methanol and waste cooking oil were 12:1, with CaO from egg shell of purebred chicken as a catalyst. CaO catalyst was yielded by calcinations egg shell of purebred chicken on 1000 ⁰C for two hours. Calcination product was characterized with X-RD to determine of CaO. Result of biodiesel was characterized based on 1H-NMR, FTIR, GC-MS, dan ASTM (American Standard Testing of Materials). Yielded of biodiesel theoretically was 40.298% and experiment was 36.779%. Main component that resulted there is methyl stearic (40.21%).
