Cassava peel is a waste product from cassava starch or modified cassava flour (mocaf) production. It is currently not utilized optimally. Cassava peel is a lignocellulosic material that can be used as a source of cellulose. Acetylation of cassava peel cellulose was successfully done using acetic anhydride with glacial acetic acid and sulfuric acid as catalysts. The content of acetyl is 49.54%, and the degree of substitution (DS) is 3.69. The percentage of acetyl of more than 43% and the DS of 3.69 show that the cellulose acetate obtained is categorized as cellulose triacetate. The CA–PEG membrane has a pore range of 1- 4 μm depending on the molecular weight of PEG. The coefficients of rejection of the CA-PEG membrane range from 95.99% to 98.88%. The CA-PEG membrane is effective as a microfiltration membrane.
