Nowadays, there is growing concern in looking for a renewable source of lubricant due to increasing demand for industrial applications besides depletion of world petroleum resource with uncertainty in petroleum supply has stimulated the search for biolubricants as an environmental friendly alternative source. Therefore, the research has been done using Jatropha curcas oil for biolubricant as new source over derived calcium oxide from Papia undulata shell as a solid catalyst. In addition, the research aims to determine the kinetic reaction for transesterification of Jatropha curcas oil on biolubricant yield. The first step in the research method was esterification process of free fatty acid (FFA) in Jatropha curcas oil, for reduction of the free fatty acid value and production of Jatropha curcas oil metyl ester (JCOME).
