Hydrolysis of Oil Palm Empty Fruit Bunch Fibers to Produce Sugar Hydrolyzate as Raw Material for Bioethanol Production

Fitriani Kasim, Anwar Kasim


A study conducted to see the effect of the regulation and control of temperature on the length of the hydrolysis of oil palm empty fruit bunches fiber and the resulting hydrolyzate sugar levels, which will be planned to be used as raw material for bioethanol. Therefore do oil palm empty fruit bunches fiber hydrolysis with sulfuric acid (H2SO4) at low concentrations (1%) using an autoclave with a temperature of 120 ° C and 130 ° C, and the time for 30, 60, 90, 120 minutes. After that the observed reducing sugar levels by using a method Luff Schoorl. The results showed that setting temperature and time influence on sugar levels resulting hydrolyzate where the optimum temperature and time to produce the highest sugar content reducing at 130 ° C with a long 60 minutes, with the resulting reducing in sugar content was 3.51%. The results obtained are much higher than previous studies conducted by researchers who carried out the straw fibers under the same conditions by using a solution of 1% H2SO4 and hydrolysis time 1 hour, but no temperature control and heating is only done on a gas stove, which acquired sugar 0.22%. As for the gain of 0.78% sugar, hydrolysis takes 4 hours, with a concentration of 10% sulfuric acid.
