ABSTRACT
The membrane is a selective and semipermeable thin layer between two phases,
namely the feed phase and permeate phase. One of the ingredients for making
membranes is cellulose acetate from pineapple leaf waste. The purpose of this
research is to make cellulose acetate membrane using cellulose from pineapple
leaf waste as the main raw material with composition variation and pressure
variations. In this research uses variations in polymer cellulose acetate are 15%
(w/w), 20% (w/w) and 25% (w/w) and pressure variations are 1 bar, 2 bar and 3
bar. The stages of making membranes are taking pineapple leaf fibers, making
cellulose acetate, making cellulose acetate membrane and testing the mechanical
properties of the membrane. At optimum condition, flux value was obtained 22.26
L/m2.h at 3 bar with cellulose acetate composition 25% w/w. While the highest
rejection value was obtained at a membrane composition of 25% w / w with COD
81.12%, BOD 76.03% and TSS 77.91% at 3 bar pressure. Based on SEM results,
the average membrane pore size obtained was 0.064 μm. The highest tensile
strength value is 7.74 mPa with 25% w/w composition of cellulose acetate. If
more cellulose acetate composition were used, the flux value will be lower and the
rejection will be higher. If pressure increase, rejection and flux value will get
higher.
Keywords : cellulose acetate, flux, membrane, rejection
