Research in the field of renewable energy development has become an interesting topic in recent years. The development of biodiesel can be done through the exploration of raw materials and the development of catalysts to produce biodiesel. On the one hand, efforts to explore biodiesel raw materials in Indonesia are supported by abundant of natural resources, both animal and vegetable, while on the other hand, the availability of renewable catalysts is supported, among others, by the development of heterogeneous catalysts. This research aims to synthesis renewable catalysts in the transesterification reaction by synthesize CaO/Fe3O4. The method used was impregnation which absorbs the active metal components in solution to the carrier solid.Then, characterize and evaluate its potential as a catalyst through a transesterification reaction in kapok seed oil. The results showed that CaO/Fe3O4 was successfully synthesized by impregnation method. This was evidenced by the XRD analysis which showed the correspondence between the CaO/Fe3O4 diffractogram and the Crystallography Open Database for calcium oxide (COD, 1000044) and magnetite (COD, 1010369). The biodiesel product with the support of CaO/Fe3O4 catalyst. The development of biodiesel can be done through the exploration of raw materials and the development of catalysts to produce biodiesel. On the one hand, efforts to explore biodiesel raw materials in Indonesia are supported by abundant natural resources, both animal and vegetable, while on the other hand, this research aims to synthesize renewable catalysts in the transesterification reaction by synthesize CaO/Fe3O4 with a mole ratio of 7:1 and an oil: methanol mole ratio of 1:15 produces a FAME yield of 66.79% with a quality in accordance with Indonesian biodiesel standards (SNI 7182-2015). © 2023 American Institute of Physics Inc..
