Abstract

Kaffir lime leaf (Citrus hystrix) is a plant that contains aromatic oil. The aroma is not liked by insects, so it can be used as a repellent. Kaffir lime leaf essential oil contains linalool, citronella, and beta-citronellol compounds which have biolarvicidal effects on mosquitoes. This study aims to formulate the essential oil of kaffir lime leaves in the form of a spray repellent against Culex Sp. In this study, the kaffir lime leaf essential oil formula was made with variations in concentration, namely formula 1 (10%), formula 2 (15%), and formula 3 (20%). The test parameters include organoleptic examination, pH test, stability test, viscosity test, skin irritation test and repellent activity test against Culex Sp. The spray formula with concentrations of 10%, 15% and 20% had protection against mosquitoes during 3 hours. Spray repellent formula with a concentration of 10% has a protection power of 50%, a concentration of 15% has a protection power of 75%, and a concentration of 20% has a protective power of 93.30%.The kaffir lime leaf essential oil (Citrus hystrix) can be formulated as an aromatherapy wax and the repellent activity of the kaffir lime leaf essential oil (Citrus hystrix) aromatherapy candle shows that the repellent activity increases along with the increase in the concentration of kaffir lime leaf essential oil.

Abstract

Research has been carried out on the determination of antioxidant activity in vitro on rambutan bark with experimental methods. The ethyl acetate fraction was obtained from the ethanol extraction of the rambutan bark from maceration. The formula was made by varying the concentration of 3 fractions, namely F0 without fraction, F1 (1%), F2 (1.5%), and F3 (2%) with organoleptic test parameters, each formula was in the form of a semi-solid, distinctive odor and different color. -different in white F0, orange F1, light brown F2 and brown F3. Homogeneity test on each homogeneous formula, viscosity test results obtained 2840cP, 2825cP, 2815cP, 2810cP for F0, F1, F2 and F3 respectively. The washing power test was found to be 32mL; 32.1mL; 30.5mL; 27.1mL for F0, F1, F2 and F3 respectively. The cream type test on each formula showed the W/A type. pH test results obtained 7,10; 7.14; 7.06; 6.97 for F0, F1, F2 and F3 respectively. Stability test on each formula showed stable results, irritation test on each formula showed that no irritation occurred. Determination of antioxidant activity using the DPPH method by looking at the IC50 value and determining the SPF value. The results of the antioxidant activity test obtained IC50 values ​​at F0 of 108.497 ppm in the medium category, F1 at 69.23 ppm in the strong category, F2 at 61.92 in the strong category, and F3 at 61.39 in the strong category. The best formula was formula 3 with antioxidant activity of 61.39 ppm in the strong category.
