Abstract
Glucose is usually used in the manufacture of liquid sugar, syrup, and as an alternative energy source such as bioethanol. One alternative material for making glucose is to use waste residues that can still be used such as solid yeast waste (yeast mud) from PT. Energi Agro Nusantara which has a fairly high carbohydrate content of 31.55%. This research was carried out in 3 stages. The first stage is the preparation of raw materials, followed by the manufacture of liquid glucose using the acid hydrolysis method, and determination of the reaction order and reaction rate constant. Hydrolysis was carried out at a constant temperature of 900C, a stirring speed of 200 rpm, a material ratio of 1:10, HCl concentration: 2.5N; 3N; 3.5N; 4N; 4.5N, and hydrolysis time: 60 minutes; 90 minutes; 120 minutes; 150 minutes; 180 minutes. The results of the study showed that the glucose synthesis reaction from yeast mud solid waste followed a pseudo first-order reaction, and the glucose content of the hydrolysis results was influenced by the concentration of HCl catalyst and the duration of hydrolysis which had a directly proportional effect. The highest glucose content obtained was 26% and the reaction rate constant (k) value was 0.0046 at a concentration of 4.5N HCl with a hydrolysis time of 180 minutes.
