Abstract

Water hyacinth is one of aquatic weeds because it becomes aquatic ecosystem problem. Many efforts were made to reduce the negative impact of these plants, which one of them with using as raw material for synthesis of microcrystalline cellulose (MCC). Water hyacinth has high potential to be McC because its cellulose content is quite high. The resulting microcrystalline cellulose will be compared with Avicel pH 101. The manufacturing process begins with the MCC a socletation extraction process, delignifikasi using mixed of 3.5% HNO3 and NaNO2 in temperatures of 90 ˚C for 2 hours, followed by heating of a mixture of 2% NaOH and Na2SO3 2 % at temperature 50˚C for 2 hours. Then the bleaching process with 3.5% NaOCl was carried out until it reached a temperature of 70˚C. The results are neutralized using distilled water. The isolation process of α-cellulose was carried out using 17.5% NaOH solution at a temperature of 80˚C for 30 minutes and bleaching process with 3.5% NaOCl was carried out until it reached a temperature of 70˚C. Alpha Cellulose lignification results with heating in the aqueous solution of HCl at concentrations of 1, 1.5 and 2 M for 30, 45 and 60 minutes. Data analysis using One Way ANOVA with a confidence level of 95%. The results of hydrolysis obtained the yield, stationary angle and optimum moisture absorption capacity of MCC which is equal to 91.70%, 20.695 and 3.241% using HCl 1.5 M concentration for 30 minutes using factorial design applications. The resulting MCC was then analyzed using FTIR and XRD. FTIR uptake of MCC results showed the presence of wave numbers at 3331.44 cm-1 and 2893.66 cm-1 which indicated the presence of OH and CH groups. The results of the XRD analysis showed that MCC had a crystallinity level of 78.23%. Keywords: water hyacinth, microcrystalline cellulose (MCC), avicel, hydrolysis,
