Synthesis of Ni/MCM-41 based on silica of Sidoarjo mud as a catalys of palm oil hydrocracking process have been carried out. The MCM-41 was synthesized using the silica of Sidoarjo mud as source of silica and cetyl trimethyl amonioum bromide (CTAB) as a template, by hydrothermal method at temperature of 100 ºC for 24 h. CTAB was removed using ethanol/HCl solution by reflux metodh. The Nickel metal from NiCl2.6H2O salt precursor was loaded to the MCM-41 using wet impregnation method with ratio of nickel metal and MCM-41 was 1:200 and 1:50 (b/b) . The MCM-41, Ni(0.5%)/MCM-41 and Ni(2.0%)/MCM-41 sample were analyzed by XRD, FT-IR, TEM, and GSA. The Hydrocracking process of palm oil was done using Ni(0,5%)/MCM-41 catalyst. Ratio of catalyst/palm oil feed = 1:50 (wt/v) at temperature of 400 ºC was used H2 gas with flow rate 20 cc/min. The hydrocracking product was analyzed using GC-MS. The result showed that The structure of MCM-41 was well-ordered and have average pore radius of 3.67 nm and surface area of 398.886 m2 g-1. Loading of 0.5 and 2.0 %(wt/wt) of nickel metal into the MCM-41 affected the MCM-41 structure. Product of hydrocracking used Ni(0.5%)/MCM-41 catalyst showed the conversion of hydrocarbon of 40.71% (wt/v) with selectivity toward gasoline and diesel fraction of 66.33% and 19.44%
