Abstract

Zeolite as a catalyst can increase its activity by carrying out physical and chemical activation processes. Physical activation can be activated by reducing the size of the zeolite through grinding and sieving methods, from the physical activation process it can increase the surface area of the zeolite. In this study, zeolite was chemically activated by acid activation method by immersing natural zeolite with HCl and HF. The oxide compound in the activated zeolite was characterized using XRF. The activated zeolite was used to reduce the free fatty acid levels with variations in the addition of 7 to 10 grams of zeolite. The content of free fatty acids is then compared with the quality requirements of cooking oil according to SNI 01-3741-2013. The results of the research conducted showed that there were differences in the content of oxide compounds in zeolite before and before activation with differences in SiO2 content, namely 69.4% before activation and an increase of 82.1% after activation. The results of the state test including physical properties, odor, and taste tests of used cooking oil that have been purified indicate that used cooking oil that has been purified meets the quality requirements of cooking oil based on SNI 01-3741-2013. Used cooking oil that has been purified has a normal taste, does not smell. rancid and yellow. The content of free fatty acids meets the requirements of SNI 01-3741-2013 for all variations of the addition of zeolite with the highest decreasing value obtained at the addition of 10 g of zeolite with a free fatty acid content value of 0.22%.

Abstract

Used cooking oil is an oil that has been used repeatedly in the process of frying food. Repeated use of cooking oil will cause a decrease in the quality of used cooking oil and if consumed will be harmful to health. The decrease in the quality of used cooking oil due to the formation of more double bonds in the structure of used cooking oil causes the oil to be more easily oxidized. The oxidation experienced by used cooking oil causes the quality of used cooking oil to decrease marked by the increasing value of peroxide number, free fatty acid content, water content and acid number of used cooking oil. One of the efforts that can be done to improve the quality of used cooking oil is to add an adsorbent to the used cooking oil. The added adsorbent serves to adsorb the impurities contained in the used cooking oil. One of the adsorbents that can be used is zeolite, zeolite can be used as an adsorbent because of the wide surface area of ​​zeolite which makes it easier for zeolite to adsorb chemical compounds on its surface. To test the quality of the oil can be done by measuring the peroxide number, free fatty acid content, water content and acid number. In this community service, training activities for refining used cooking oil will be carried out to the people of the Tanjung Gedong area, Tomang, West Jakarta. The link between PkM training in refining used cooking oil using natural zeolite for residents of the Tanjung Gedong area, West Jakarta and PkM flagship usakti, namely in the areas of regional development, ecogreen, and alternative energy. Namely using natural materials such as zeolite which is environmentally friendly to improve the quality of used cooking oil.
