TERHADAP BILANGAN PEROKSIDA MINYAK JELANTAH"^^ . "Used cooking oil is cooking oil that has been damaged, one of which is\r\ncaused by exposure to oxygen. Exposure to oxygen in the oil triggers oxidation so\r\nthat the oil smells rancid and decreases the quality of the oil. Furthermore, the\r\ndecrease in the quality of the oil was indicated by an increase in the peroxide\r\nvalue of the oil. One of the ways to reduce the peroxide value in the oil is by\r\nadding natural antioxidant. One of the natural ingredients tested for antioxidant\r\ncontent is bidara leaf extract. Bidara leaf extract is produced from extraction\r\nusing methanol by the maceration method. Bidara leaf extract has bioactive\r\ncompounds including flavonoids and saponins that function as antioxidants.\r\nAntioxidant activity in bidara leaf extract was tested by DPPH method (Dhiphenyl\r\npicryl hydrazil) with a comparison solution of BHT (Butylated hydroxytoluene) at\r\na wavelength of 516.5 nm. The antioxidant activity of bidara leaf extract was\r\nlower than BHT with IC50 values of 9.53 g/mL and 3.7 g/mL, respectively. The\r\nantioxidant activity of bidara leaf extract and its effect on peroxide levels were\r\ntested by mixing the extract into used cooking oil. The average peroxide value of\r\nused cooking oil after the addition of bidara leaf extract was 8.6402 O2/Kg. This\r\nvalue is lower than the average used cooking oil without the addition of bidara\r\nleaf extract of 8.9366 O2/Kg. Finally, statistical testing with the t-test revealed a\r\nsignificant effect on the administration of bidara leaf extract on the peroxide\r\nvalue of used cooking oil with a p-value <0.05."^^ .
