Abstract:
Cassava pulp is a solid waste from the cassava starch extraction process. This
waste needs to be treated because cassava pulp produces odor pollution. Cellulose amounts
to approximately 58 wt.% of the fiber content in the cassava pulp. Due to its high cellulose
content, one of the solutions is to convert the cassava pulp into lactic acid by alkaline
hydrothermal processes. Pretreatment is added to increase the efficiency of the alkaline
hydrothermal reaction by hydrolyzing cellulose into monosaccharides such as glucose and
fructose, which are common starting materials for lactic acid production. However, the aid
of alkaline catalysts such as Ba(OH)2 and NaOH is essential to facilitate the formation of
lactic acid. Microwave irradiation is an environmentally friendly heating, and the assistance
from microwave irradiation can produce a higher reaction rate and consumes a shorter
operating time. This study investigates the lactic acid yield under different conditions using
a microwave-assisted alkaline hydrothermal reaction using Ba(OH)2 as a catalyst. The
parameters investigated are Ba(OH)2 concentration (0.1 1 M) and microwave power to
obtain the highest yield. The highest lactic acid yield is obtained with 0.7 M of Ba(OH)2 for
25 minutes in a 1000W microwave which produces the lactic acid yield of 17.17% (g lactic
acid/g biomass).
