Abstract
SPO contains high fatty acids with a palmitic acid content of 87.26 % and potentially can be converted into biodiesel. Optimization of SPO esterification using a sulfonated carbon montmorillonite catalyst from glucose has been conducted using Response Surface Methodology (RSM) with Central Composite Design (CCD) to produce biodiesel. The input parameters observed were temperature of 63.18-96.82 °C, catalyst weight of 0.3-3.7 g, and reaction time of 69.54-170.46 minutes and the output parameter were free fatty acid conversion percentage. The optimum conversion percentage was 88.02% at a temperature of 80.51 °C, catalyst weight of 2.25 g, and reaction time of 170.45 minutes. The value of the coefficient of determination (R2 = 0.895) indicates that the quadratic model is relatively accurate enough to estimate the optimal input parameters. FTIR analysis showed that the esterification product's functional groups C=0 and C-O were shown at 1713 cm-1 and 1088 cm-1, respectively. Determination of the density and viscosity indicates that the biodiesel product have been qualified according to SNI-04-7182-2006.
