Synthesis of proton conductive membranes based on acid-base complex pair: bacterial cellulose (BC) and benzotriazole (Btri) has done. Microbial cellulose is derived from bacterial cellulose market, known as nata de coco. Nata de coco was pulverized and washed with solution of NaClO 2% then heated for 30 minutes to boil. Proton conductive membranes have made by mixing the bacterial cellulose powder and distilled water, stirred for 24 hours with a magnetic stirrer, after it was added benzotriazole with the mass ratio between bacterial cellulose and benzotriazole; 1: 0.20, 1: 0.25 and 1: 0.30, and stirred for 24 hours with a magnetic stirrer continued at the casting stage, drying at a temperature of 50°C for 36 hours. Characteristics of the material obtained was studied by using FTIR analysis for functional groups, XRD analysis to study diffractogram pattern of the resulting material, and SEM analysis to show the morphology of the material, as well as proton conductivity. The results show that conductivity of membranes based on acid-base complex pair bacterial cellulose and benzotriazole in the ratio 1: 0.25 g/g has proton conductivity 1.7 x 10-5 S/cm.
