Background: Meranti wood sawdust (MWS) is a liglocellulosic materials that contains of three main components of polymer which are cellulose, hemicellulose and lignin. It is consist of > 29% of xylan that made up from pentose sugar xylose. Objective: To compare the production of xylose from Meranti wood sawdust (MWS) by using chemical method and combination system method (physical and biological process). Results: Chemical process showsmuch faster reaction timein order higher xylose productionthan combination system method, but the production of byproduct (furfural) is main disadvantagesin chemical process. The maximum yield obtained were 14.13 g/l and 13.60 g/g using 40 minutes acid hydrolysis and 1455 minutes reaction period in combination system method respectively. Conclusion: The results obtained from the present study clearly indicate that the potential utilization of MWSby using both methodfor the production of xylose which can serve as functional food ingredients such as xylitol.
