Abstract: Silica gel is a glassy grain with a very porous shape. Silica is made synthetically from sodium silicate. In this study, volcanic ash can be used as silica, which is silica can be applied in the manufacture of composite membranes as fillers because it can increase the conductivity of composite membranes. The method used for making silica gel was extraction method and composite membrane made using phase inversion method with the composition of chitosan and silica used are 2 grams of chitosan and variations of fillers 0.6, 0.9 and 1.2 grams of silica, and the stirring time is 8,12 and 16 hours. The characteristics and analysis carried out in this study were FTIR and SEM. Based on the results of the study, the best membrane conditions were obtained from composite membrane analysis with a tensile strength of 34,118 Mpa. In the Scanning Electron Microscopy (SEM) analysis, the lowest composite membrane has a dense and homogeneous pore, while the highest composite membrane has a hollow pore and has been homogeneous.
