ABSTRACT
Used cooking oil is frying oil that contains carcinogenic compounds such as free
fatty acids, peroxides and others. To reduce the risk due to the impact of used
cooking oil, researchers are interested in recycling used cooking oil by carrying
out a purification process using cassava peel charcoal as an adsorbent. This study
aims to determine the effect of charcoal weight and length of purification with
cassava peel on the characteristics of the purified used cooking oil and to
compare the characteristics of used cooking oil before and after purification. The
operating conditions of the study were the weight of the adsorbent 2; 4 and 6
grams and a purification time of 6; 8 and 10 hours. Making cassava peel charcoal
is done through a process of dehydration, carbonization, and activation using
0.5% NaOH. Furthermore, the purification process is carried out using the
adsorption method. From the research conducted, it was found that the
characteristics of the oil before purification were used cooking oil (A0) which had
a blackish brown color, rancid smell, taste, water content 1,82%, ALB 1,08%,
and peroxide value 22,93 mEqO2//Kg. Meanwhile, the oil after purification
obtained the best results in until D3 with operating conditions of 6 grams of
activated charcoal weight and 10 hours of purification has an orange-yellow
color, no rancid smell, tasteless, 0,1% water content, 0,29% ALB and peroxide
value 9,21 mEqO2/Kg.
Keywords: Adsorbent, Activation, Cassava peel, Used cooking oil.
