Chitosan / PVA / MMT composite membrane synthesis has been successfully carried out using the phase inversion method. In this study, chitosan/polyvinyl alcohol as a polymer matrix, K-montmorillonite (MMT) as an inorganic filler with sulfuric acid as a crosslinking agent. The purpose of this study was to study variations in the concentration of montmorillonite (1, 2, and 4%) on the properties and performance of composite membranes. The results of the composite membranes synthesis were confirmed by the presence of a unique functional group absorption in FTIR. Modifications with polyvinyl alcohol (PVA) and montmorillonite can improve the properties and performance of composite membranes. Increasing concentration of montmorillonite tends to increase water uptake and methanol uptake. The CS / PVA / MMT 4% membrane is a promising membrane with better performance than other membranes, with high water absorption and low methanol absorption, besides it has a very low methanol permeability value of 7.165 x 10-8 cm2 / s.
