Anti-Oxidant Tests of starfruit and pineapple pulp on the quality of Used Cooking Oils   ABSTRACTUsed Cooking Oil is oil produced from frying residue and is carcinogenic because it causes oxidation, hydrolysis, and polymerization to produce toxic peroxides and free fatty acids that are difficult for the body to digest. Measurement of oil quality can be measured through 3 parameters, namely, the peroxide number, the acid number and the oil color. Efforts to control the quality of cooking oil are the addition of natural antioxidants, starch wuluh and pineapple pulp. Starfruit contains flavonoids, terpenoids, phenols and pectins as well as Vitamins C and A which can absorb free radicals in oil. Meanwhile, pineapple pulp contains high levels of vitamin C, flavonoids and polyphenols which can eat free radicals. This Research aims to determine the differences in the antioxidant power of starfruit and pineapple pulp to maintain the quality of used cooking oil. This research is experimental, which will study the antioxidant power of starfruit and pineapple pulp at the acid number, peroxidant and color intensity of used cooking oil. 3 grams of dry starfruit and 0.4 grams of dried pineapple pulp are added to each pad 100 mL of used cooking oil. The application of starfruit and pineapple pulp in used cooking oil had a significant effect on the 3 oil quality parameters, namely the acid number, the peroxide number and the oil color intensity, with a significance value of P <0.05. This is because the antioxidant content and composition of the two ingredients are different. Wuluh starfruit in the addition of 3 grams provides a fairly large antioxidant effect, while pineapple pulp at a concentration of 0.4 grams has shown anti-oxidant power so a higher concentration is needed to produce optimal antioxidant power. Keywords: Antioxidants, Starfruit, Pineapple Dregs

The development of biodiesel which is currently increasing has helped increase glycerol as a by-product. The glycerol can be obtained from a transesterification reaction in either vegetable or animal oils or fats and even used cooking oil. Glycerol buildup without further processing can reduce the selling price of glycerol. One solution to overcome this is to convert it to surfactants such as glycerol esters which are widely used in various industries such as chemistry, food, cosmetics, medicine and textiles. This study aims to utilize used cooking oil as a source of glycerol used in the synthesis of glycerol ester surfactants, as well as to compare the quality of glycerol ester surfactants produced by the use of commercial glycerol. The process begins by isolating glycerol from used cooking oil and then purifying it to improve its quality. Then glycerol ester was synthesized by using stearic acid, palmitic acid and oleic acid at reaction times of 120, 150 and 180 minutes. The highest yield of ester glycerol produced was at the reaction time of 180 minutes for each use of fatty acids. The test results showed that the glycerol ester produced was able to reduce the surface tension of the water. The value of hydrophylic-lipophylic balance (HLB) is not much different in the range of 5, and the use of various fatty acids and different sources of glycerol results in % of the stability of different emulsions.
