Abstract

Water hyacinth is lignocellulosic biomass that has the potential for glucose production because it contains 64.51% cellulose. Hydrolysis of water hyacinth was done in a rotating reactor with a microwave as a heat source. This study aims to obtain glucose by determining the hydrolysis reaction rate constant of power and sulfuric acid (H₂SO₄) concentration function and to find the best conditions for this hydrolysis process. Several research variables were H₂SO₄ concentration (0.5 N; 1 N; and 1.5 N), microwave power (600 W and 800 W) and reaction time of 60 minutes. Parameters measured were hydrolyzate temperature, glucose, and cellulose content. The hydrolysis reaction rate constant obtained based on the Arrhenius equation was k =1.30 x 10^-2 e^-132.172/Tand the relationship between H₂SO₄ concentration and microwave power was C = 0.001P. The best conditions were obtained using 1 N H₂SO₄ and microwave power of 600 W with final glucose content of 486 mg/L.
