Characterization of the ZSM-5 zeolite membrane synthesized with 304-200 gauze buffer was carried out. The purpose of this study is to first synthesize ZSM-5 membranes with 304-200 g auze buffer in various pretreatments. The second objective is to characterize the synthesized ZSM-5 membrane with X-Ray Difraction (XRD), Scanning Electron Microscope Energy dispersive X-Ray Spectroscopy (SEMEDS) and The fourier-transform infrared (FTIR). ZSM-5 membrane was synthesized through the first step, namely the pretreatment variation of 304-200 stainless steel gauze soaked in toluene 95% for 2 hours, in a 15% HCl solution for 20 minutes; immersed in 15% NaOH, 15% HCl, and electrooxidated with 20% H2SO4 for 20 minutes each; immersed in toluene 12 hours, in a solution of HCl 15% 6 hours and in TPABr solution 0.1 M 12 hours. The next step is the manufacture of ZSM-5 precursors, and the coating process on the gauze buffer at 90 ° C for 4 days. The resulting ZSM-5 membrane was characterized using XRD, SEM-EDX and FTIR. Based on XRD, SEM-EDX, and FTIR characterization of the synthesized product, it was concluded that pre-treatment of 304-200 gauze that can produce a good ZSM-5 membrane is pretreatment immersed in 15% NaOH, 15% HCl, and 20% H2SO4 electrooxidation respectively each for 20 minutes; and soaked in toluent 12 hours, HCl 15% 20 minutes, and TPABr 0.1 M 12 hours. The resulting membrane is the ZSM-5 membrane.
