Therefore, used cooking oil processing efforts were made to improve its quality by using activated charcoal adsorbent of Tectona Grandis L. F sawdust. This study aimed to improve the quality of used cooking oil through refinign by using charcoal adsorbent of Tectona Grandis L.f sawdust. used cooking oil samples were obtained from Ogoamas 1 Village, Sojol Utara District, Donggala Regency. Based on the results of testing the quality of the oil obtained, the water content was 0.22%, free fatty acid content was 0.25% peroxide number was 1.83 meq / Kg, the iodic number was 45, specific gravity was 0.900 g / mL and oil color clear oil with absorbance value was 0.031 A. Based on the quality of several parameters of cooking oil using activated charcoal of Tectona Grandis L.f sawdust, it has fulfilled the quality requirements of cooking oil according to SNI 3741-1995.]]>
