ABSTRACT
The purpose of this paper was to find the suitable condition between glycerol concentration and heating time
treatment in the process of delignification and bioethanol production. The
production of bioethanol consisted of 3 main stages: hydrolysis, fermentation, and distillation.
The best result was obtained by a glycerol
concentration of 90% and 15
minutes of heating time. It was used to delignify the lignocellulose biomass waste of the
sago dregs originally containing 36.56% of lignin, 37.6% of a-cellulose and 39.51% of holocellulose. Then after being delignificated by 90% of glycerol
concentration with 15 minutes heating time, the lignin content decreased to 19.3%, while a-cellulose increased to
39.64% and holocellulose also increased to 62.18%. After the delignification was successful,
it was followed by
the bioethanol production to produce 25% of bioethanol. This research is expected
to overcome the problem of the energy crisis, food crisis, and environmental pollution
by the sago dregs.
