Repeatedly use of cooking oil can cause increasing free fatty acids and peroxide value contained. Therefore, continuous exposure to used cooking oil has known resulting hazardous impacts on the environment and also to human health. Hence, it is necessary to purify used cooking oil before it is discharged to the environment. Durian peel contains high cellulose ranging from 50% - 60%, which is eligible to be used as carbon adsorbent's raw material for used cooking oil purification. This study produced a kind of carbon adsorbent from durian peel through a carbonization process that lasted for 2 hours at 500°C combustion temperature with a chemical activation using H2SO4 1 N. This study was carried out with the adsorbent weight of 6 grams and various contact times of 30, 60, 90, 120, and 150 minutes. The most favorable results obtained after contact time was 0.0637% of free fatty acid, 0.41 meq O2/kg of peroxide value, and 0.9022 gr/ml of density, respectively, at 150 minutes contact time.
