| dc.description.abstract | The purpose of this research are to study the effect of sugarcane bagasse
powder concentration, hydrolysis temperature and time on the %yield of glucose
produced and the level of glucose by recycle vinasse process. glucose by the level of
glucose from recycling vinasse as the raw material. Raw sugarcane bagasse as
primary material was obtained from sugarcane juice shop. Observed variabels were
concentration of sugarcane bagasse in aquadest, hydrolysis time and temperature.
Sugarcane bagasse is powdered by blender and then mixed with aquadest (2,94;
3,85; 4,76%) and hydrolized in the hydrolysis tank. The hydrolysis process occurs at
time (1, 1,5 and 2 hours) and temperature 135, 150 and 165°C. And then, the
hydrolysis product is tested for its glucose, lignin and cellulose composition. After
that, the product is fermented in order to produce bioethanol. Result shows that %
yield of glucose increases as the escalation of sugarcane bagasse powder
concentration, hydrolysis time and temperature. But, % yield of glucose increases
from 1 until 1,5 hour of hydrolysis time and then decreases from 1,5 to 2 hour of
hydrolysis time. The highest %yield of glucose obtained at concentration 2,94%, 165
°C and 2 hours of hydrolysis time. Beside that, lignin and cellulose level fluctuated
as the increasing of hydrolysis temperature. This could be caused of the non-uniform
composition of the raw materials. | en_US |
