    Abstract

    Abstract: During the frying process, cooking oil oxidized and hydrolysed so triglycerides break down into other compounds like free fatty acid, peroxide acid and the water content is higher than the new cooking oil so it is not feasible to reuse. Hence, it is necessary to improve the quality of waste cooking oil through adsorbtion process. The present work aimed to decrease the amount of peroxide value, free fatty acid value, and acid value of waste cooking oil using integrated adsorber equipment through the medium of activated carbon made from coconut shell. The experiment were conducted at temperature 60oC, 90oC, and 120oC. And also100 rpm, 200 rpm, and 300 rpm. The result of the study showed that the minimum percent of free fatty acid is 0.768% at a temperature of 120oC and 300 rpm stirring speed, where as the percent free fatty acid before adsorption is 3.1744 %. The minimum acid value of the oil obtained at a temperature of 120oC and the stirring speed of 200 rpm is equal to 1.9074, whereas the acid value before adsorption is 3.927. While the minimum peroxide value derived from temperature and stirring speed of 300 rpm at 60oC is 5.38, whereas the peroxide value before adsorption is 20.59.
