Abstract
This research aims to investigate the effect of sulfuric acid concentration and hydrolysis temperature on the characteristics of microcrystalline cellulose (MCC) derived from cassava stems (Manihot esculenta). The MCC production process involved several stages, including raw material preparation, delignification, bleaching, and acid hydrolysis. The variables studied were sulfuric acid concentrations of 1.5 N, 2 N, 2.5 N, 3 N, and 3.5 N, and hydrolysis temperatures of 60°C, 70°C, 80°C, 90°C, and 100°C. The results showed that increasing the sulfuric acid concentration and hydrolysis temperature significantly affected the yield and cellulose content produced. The optimum condition was obtained at a concentration of 2.5 N and a temperature of 80°C, resulting in the highest yield and cellulose content that met the British Pharmacopeia standard for microcrystalline cellulose. Particle size analysis (PSA) indicated a uniform particle size distribution, X-ray diffraction (XRD) revealed a high degree of crystallinity, and scanning electron microscopy (SEM) showed irregularly shaped particles with smooth surfaces. These results suggest that cassava stems have strong potential as an alternative raw material for the environmentally friendly and economically valuable production of microcrystalline cellulose.
