Abstract

Alpha cellulose is a pure form of cellulose. Cellulose is a natural polymer in the form of carbohydrates (polysaccharides) that has fiber which is white, insoluble in water, renewable, easily decomposes, and non-toxic. Cellulosic sources are abundant in nature even in untapped biomass wastes. In this study, cellulose was isolated from Empty Palm Oil Bunches (EPOB) of 45% and Dry Jackfruit Leaves (DJL) of 21.45%. This study aims to obtain optimum yield of cellulose at NaOH concentration and cellulose characterization with water content, FTIR, and SEM analysis. The optimum α-cellulose yield was determined by alkali process with 8, 10, 12 and 14% (w/v) NaOH variations at 90-100 °C for 3 hours to remove hemicellulose and lignin followed by bleaching process with H2O2 10% (w/v) at 80-90 °C for 1.5 h to obtain pure α-cellulose. The optimum yield of EPOB cellulose was 38,562% in 12% NaOH and DJL was 7.27% in 10% NaOH. The water content in OPB cellulose was 4.38% and DJL was 6.37%. A typical cellulose-forming functional group seen in FTIR (Fourier Transform Infra-Red) and morphological results appears in SEM (Scanning Electron Microscopy) analysis. From FTIR analysis result shows cellulose from EPOB and DJL contains O-H, C-H, and C-O. SEM analysis shows fibers from EPOB and DJL are uniform and have pores. However, DJL fibers have white patches, which suspected to be impurities.
