Sago hampas which contain lignocellulosic compound have potential for production ofxylose which later can be fermented into xylitol. The demand for xylitol has been increasing and become vital for most of the countries. In this study, sago hampas lignocellulosic compound was used as raw material for obtaining xylose. The targeting polymer is hemicellulose component which was breakdown to xylose through dilute sulphuric acid pretreatment. This study was conducted to determine the effect of acid concentration and solid to liquid ratio concentration on sago hampas pretreatment for xylose production. The maximum xylose concentration (6.3 g/L) was obtained at 121 •c, for 60 min, at acid concentration 2.0 %. For solid to liquid ratio, the xylose produced the most (9.0 g/L) at 121 •c, for 60 min, with substrate loading 7.0 %. This results indicates that the enzymatic hydrolysis of sago hampas able to increase xylose concentration.
