after delignification process by 40-50 (%). Cellulose obtained in the process
of pretreatment and delignification can be used for raw material in the process fermentation to obtain glucose.

Biomass pretreatment process requires lignocellulosic prior to delignification process, with the aim to break
down the lignin in the bamboo become protective structures of lignocellulosic, as well as making cellulose or
hemicetlulose which is more easily in the delignification. The delignification process is used to
remove compounds of lignin and pentos in bamboo, making cellulose becomes optimum.
Variables remain in pretreatmentprocess is bamboo powder 100 mesh size, the volume sulfuric acid as
much as 200 ml, water volume 3 liters, and the stirring speed 200 rpm. The free variables consist of heavy
bamboo 50-250 grams, delignification time is 30-150 minutes, and delignification temperature is 25-125(°C).
The early bamboo composition of cellulose levels 42.4-53.6 (%), lignin levels 19.8-16.6(%), pentosan
