dc.description.abstractImpregnation of KOH on blood cockle shell catalyst is one of the ways to improve the catalyst performance in biodiesel synthesis. The presence of new base sites due to increased base catalyst performance to increase the convertion of triglycerides into biodiesel. In this study, the catalyst was derived from decomposition of blood cockle shells at 800 °C for 5 and 10 hours. The catalysts was impregnated with KOH by wet impregnation method (percentage K: 1, 3 dan 5%). Type of minerals contained in blood cockle shell catalysts before and after impregnated with KOH (percentage K: 1, 3, and 5%) were Portlandite (Ca(OH)2) and Calcite (CaCO3). The CKD-10-5K catalyst had the highest basicity and potassium were 2,0333 mmol/g dan 6,00%, while CKD-5-1K had the highest surface area was 33,8911 m2/g. The optimum biodiesel result was 81,74% obtained from transesterification of waste cooking oil using CKD-10-5K catalyst by the reaction conditions were weight catalyst 3 g, oil and methanol mole ratio 1:6, reaction temperature 60±2 ºC and reaction time 3 hours. It has been observed that the basicity has much influence on the catalytic activities impregnated-KOH catalysts towards transesterificationen_US
