The Synthesis of cellulose acetate membrane water hyacinth to filter the motor vehicle exhaust emissions. Research methodology was conducted by making cellulose acetate from water hyacinth, then it would be processed by producing the membranes with acetone and formamide solvents, and the last, the membrane would be synchronized with the motor vehicle exhaust gases. The results of cellulose acetate were characterized using FT-IR. After that, the membrane synthesis products would be tested by emission test process to filter motor vehicle exhaust emissions. As a result, one of the exhaust gases that had been successfully filtered was CO (carbon monoxide) which still widely existed in motor vehicle exhaust gases. The results of FT-IR were proven by the formation of diacetate cellulose as a membrane material in the presence of a typical absorption band, the carbonyl group (C = O) at wave number 1749.2 cm-1. The membrane would be the best cellulose acetate ratio if its membrane had a ratio of cellulose acetate= 16%, formamids= 8%, acetone= 76%, and gas emissions for CO= 0.26%. The microstructure test also showed the comparison obtained by high pore density and thickness. Membrane that had cellulose acetat = 16%, and acetone = 76%, had the potential to filter Co in the air.
