The modification of catalyst conducted in this research were activation of bentonite using HF 1% and H2SO4 1.2 M, pillarization of bentonite by Al2O3 and impregnation of Ni metal. The catalyst were characterized with X-ray diffractometry (XRD), Atomic Absorption Spectrophotometry (AAS), X-ray Fluoresence (XRF), Gas Sorption analysis (BET), Transmission Electron Microscopy (TEM), Fourier Transform Infra Red (FTIR) and gravimetric method. The hydrocracking process was carried out in a reactor at 500 ºC for 2 hours and the product was analyzed with GC-MS (Gas Liquid Chromatography-Mass Spectrometry) method. The result showed that surface area, pore radius, total pore volume, and acidity of Ni-Al2O3/bentonite were 63.075 m2/g, 9.34 Å, 1.47 cc/g and 3.25 mmol/gram respectively. The highest conversion which was obtained was 65.46%. These result showed that impregnation of Ni metal increased the catalytic activity of the catalyst from 48.83% into 65.46%.
