Abstract

Cooking oil are the basic need in cooking, providing aroma, taste, and nutritional value to food. Repeated use reduces the quality and producing waste cooking oil that is harmful to health due to oxidation, hydrolysis, and polymerization. The use of activated carbon as an adsorbent is effective for clarifying waste cooking oil, removing impurities and chemical compounds. Waste-based activated carbon, such as rice husks offers an environmentally friendly and economical alternative. This study reports use of a combination of activated carbon from jackfruit skin and cornstarch. Jackfruit peel was chosen because of its high cellulose, while cornstarch helps bind impurities in oil. After that, several tests were carried out on the properties of waste cooking oil. Activated carbon from jackfruit peel in waste cooking oil was proven to be able to reduce the density value to 0,96 g/mL, flow rate 0,26 mL/s, acid number 6,53 mgKOH/g and saponification number 205,53 mgKOH/g.
