The synthesis of the KCaF 3 catalyst was conducted with several variations in the mole ratio of CaCO 3 to KF (1:1, 1:2, and 1:3). The research results showed that the addition of KF can affect the characteristics of the catalyst. The optimal catalyst is the KCaF 3 catalyst with a mole ratio variation of 1:3. X-ray diffractometer analysis revealed that the highest KCaF 3 phase composition reached 74.05%, while thermogravimetric analysis indicated a CaCO 3 concentration of 34.50%. Surface Area Analyzer analysis shows that KCaF 3 has the largest surface area, which is 187.1 m 2 /g. This catalyst efficiently facilitated the transesterification of palm oil, yielding 93.4% biodiesel.}, issn = {2597-9914}, pages = {388--394} doi = {10.14710/jksa.27.8.388-394}, url = {https://ejournal.undip.ac.id/index.php/ksa/article/view/59356} }
