Abstract
Water hyacinth (Eichornia crassipes) is an aquatic plant that can disrupt aquatic ecosystems. This plant contains high cellulose and has the potential to be a source of microcrystalline cellulose (MCC); therefore, it has high economic value. This study aims to determine the optimal hydrolysis conditions to isolate MCC from water hyacinth. The optimum conditions were designed with a 32 factorial design with acid concentration and hydrolysis time as independent variables and MCC physical properties as dependent variables. Based on the DX®10 analysis, the optimum conditions were obtained at an acid concentration of 1.5 M HCl for 30 minutes. Under this optimum condition, the yield of MCC was 91.70% with the angle of repose of 20.695 and moisture absorption capacity of 3.24%. Furthermore, the FTIR and X-ray spectra indicated that MCC of water hyacinth had the same peaks like that of Avicel® PH101.
