Fabrication of polymer-based membranes polyether sulfone (PES) which is hydrophobic which is easily experiences fouling and will a decrease in membrane performance with the addition of various organic additives from oil palm empty fruit bunches (OPEFB) waste and dimethyl formamide (DMF) as solvents to look at the formation of Ultrafiltration membrane pores (UF). OPEFB additive concentration variations were 0%, 0.5%, 1%, and 1.5% for each addition of 18% PES polymer. The manufacture of cellulose was alkalization, bleaching, and acid hydrolysis. The characteristics were carried out by the FTIR test to see the wavelength of OPEFB cellulose where at 1093.64 cm -1 there is a C-O functional group which proves the presence of cellulose in OPEFB, SEM, and porosity tests on the membrane. Membranes with polyether sulfone polymer are prepared by a phase inversion process. The results obtained by the flux values with variations in additive concentration and pressure variations of 0.5 %, 1%, and 1.5% obtained flux and rejection results (selectivity) using FeCl3. © Published under licence by IOP Publishing Ltd.
