Abstract
This research is about activated carbon of Arabica coffee grounds activated with H3PO4 as an adsorbent for refining used cooking oil. The purpose of this study was to examine the effectiveness of the mass effect of activated carbon adsorbent activated carbon of Arabica coffee grounds (Coffea arabica) activated with H3PO4 on the purification of used cooking oil. The activated carbon of Arabica coffee grounds is sifted with an 80 mesh sieve. Tests carried out included proximate tests on activated carbon including water content, ash content, volatile matter, fixed carbon, Fourier Transform Infra Red (FTIR) and oil quality tests including free fatty acids, and peroxide value. The results of the proximate test showed that the activated carbon of Arabica coffee grounds activated with H3PO4 complied with SNI No.06-3730-1995 with a moisture content of 4.2816, ash content of 3.4251, volatile matter content of 9.6843, fixed carboncontent of 82.6089. The results of the oil quality test were obtained by varying the mass adsorption of 5 grams, 10 grams, and 15 grams of activated carbon as follows: Free fatty acids have decreased from 1.1083% to 0.3522%. and the peroxide number has decreased from 4.0962 mek O2/kg to 1.8381 mek O2/kg after being adsorbed using activated carbon for 30 minutes. The oil resulting from adsorption of free fatty acids does not meet the SNI No.7709:2019 value, but for the peroxide value the value already meets SNI No.7709:2019.
