Disposing of solid waste had become the great challenges in today’s world. Thus, there is an urgency to transform the solid waste into an added value product. Sawdust is one of the solid wastes which can be hydrolyzed into glucose. This research focuses on the effect of sawdust species and particle size during glucose production. Three species of sawdust have been chosen in this research which was Meranti, Keruing and Kempas. Each species of sawdust were prepared in four different particle sizes which were 160 μm, 200 μm, 315 μm and 630 μm. After several steps of pretreatment to recovery the cellulose from the sawdust, enzymatic hydrolysis method was used to produce glucose from cellulose. The highest cellulose recovery was obtained from the Keruing species with the particle size of 630 μm. Furthermore, the highest glucose production after the enzymatic hydrolysis was Keruing species with the particle size of 200 μm. From this research, it is recommended that Nuclear Magnetic Resonance Spectroscopy (NMR) and Thermal Gravimetric Analysis (TGA) can be used to determine the detail characteristics of cellulose and glucose that has been produced from sawdust.
