dc.description.abstractCaO catalyst is a heterogeneous base catalyst which has been widely used in biodiesel synthesis. Hydration-dehydration is one of the newest methods in the synthesis of CaO catalysts which is considered quite efficient in increasing biodiesel yield. The purpose of this research is to synthesize K2O/CaO catalyst using KOH-impregnated hydration-dehydration method in biodiesel production and to characterize the catalyst using XRD (X-Ray Diffraction) to determine the type of mineral and crystal size as well as the crystanillity of the catalyst. Transesterification is a reaction between oil and methanol to produce FAME (Fatty Acid Metil Ester). The catalyst was tested in biodiesel synthesis with variations in reaction temperature (50, 55, 60, 65oC). As for the optimum conditions produced, the maximum yield of biodiesel is 83.03% using a catalyst K2O/CaO (3%K) with a purity of 96.95% obtained under the condition of a mole:oil ratio of 1:6, catalyst weight of 3% (w/w), reaction time of 3 hours, stirring speed of 500 rpm, and reaction temperature of 60oC. The characteristics of biodiesel produced in this study are water content of 0,05% (%v/v), specific gravity of 870,9 kg/m3, viscosity of 3,2 mm2/s, carbon residue of 0,28%, acid number of 0,49 mg KOH g-1 and lathering number of 217,398 mg KOH g-1. In general, the characteristics of biodiesel have occupy SNI 04-7182-2015 except carbon residues. Based on the results of the study, it shows that K2O/CaO is a good catalyst used in the transesterification process for biodiesel production.en_US
