The purpose of this research is to study hydrocracking process of nyamplung oil using 5% and 15% CoMo catalyst and supported on γ-Al2O3 and SiO2. Catalyst was prepared using wet impregnation method and calcined at 500oC for 5 hours without sulfidation process. The X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM) were performed to analyze the crystalinity and surface morphology. Based on the XRD that MoO2 was deposited on the surface of the catalysts. The hydrocracking of nyamplung (Calophyllum inophyllum) oil was conducted in Parr pressure reactor at 350oC and 3 MP. Hydrocracking product was analyzed by using Gas Cromotography – Mass Spectrometry (GCMS). The highest catalytic activity was obtained by 15% loading CoMo over γ-Al2O3 and the highest yields were 39.58% gasoil, 31.32% gasoline and 7.44% kerosene.
