The research is intended to synthesize zeolite from Silica sol H-ZSM-5 –( LUDOX HS-30 colloidal silica, 30% wt SiO2 ). As the silica source on synthesis by studying the effect of the various variables of H-ZSM-5 zeolite synthesis. As the silica source on synthesis by studying the effect of the various variables of H-ZSM-5 zeolite synthesis include the temperature at 60, 90, 110, 130° c , The rate used is 20:1. By studying the physical characteristics and the time spent in the process hydrothermal. From trial found that condition is appropriate synthesis zeolite H-ZSM-5 is the temperature at 90° c, the time required for 15 days. Zeolite after reactive is crystallization powder, coarse and are arranging is clearly crystal. The XRD patterns with positions that occur in the range Scale 8-10 and 20-25.Same standard of H-ZSM-5 and the proportion of Si/Al is the tendency of inserting more and constant at 19:1%
