Abstract

The purpose of this study was to optimize the in-situ transesterification process of biodiesel from nyamplung (Calophyllum inophyllum L.) seed using the microwave. In this study, three independent variables (microwave power, KOH concentration and in-situ transesterification time) were explored. The optimum in-situ transesterification conditions obtained by Box-Behnken Design (BBD) were as follows: microwave power 502.124 W, KOH concentration 0.499241% and in-situ transesterification time 19.0717 min. Under these optimized conditions, the yield of biodiesel reached 60.5887%. The predicted values indicated that the model equation for optimization of the in-situ transesterification process of biodiesel from nyamplung (Calophyllum inophyllum L.) seed by response surface method was matched reasonably well in accordance with the actual observed values. It can be seen from the suitability of the model equation for predicting the central point response value that was tested under the central point conditions.
