- The aim of this research was to determine the effect of NaOH concentration on cellulose characteristics from palm midrib and to determine the optimum condition of synthesis of CMC using cellulose source from palm midrib with the synthesis factors such as concentration of NaOH, NaMCA level, and reaction temperature with the response degree of substitution (DS). Research was carried out with the isolation of cellulose using NaOH solution with a concentration of 8, 12, 15, 18%. Cellulose powder were then analyzed for moisture content, ash content, yield, cellulose content, WHC, OHC, lightness, functional groups, and crystallinity. Cellulose powder produced with the highest cellulose content was then used as main material for synthesis of CMC. Synthesis of CMC was optimized using Response Surface Methods with the observed responses are degree of substitution (DS) and the independent variables such as the concentration of NaOH, NaMCA level, and reaction temperature. CMC synthesis. CMC that has been optimized further characterization by several parameters such as water content, pH, viscosity, purity, WHC, OHC, lightness, functional groups, and crystallinity. Cellulose powder isolated using 15% NaOH has the highest cellulose content of 89,63%, 9,3% moisture content, 2,12% ash content, 37,32% yield, 5,4 g/g WHC, 2,99 g/g WHC, 90,83 lightness, and 31,57% crystallinity. The optimum condition for the synthesis of CMC obtained with 10% NaOH concentration, NaMCA weight of 4.57 grams, and a reaction temperature of 46.59oC. CMC that has been optimized has the characteristics such as DS 0, 75, purity of 91.12%, pH 6,72
