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

Daun pacing merupakan tanaman yang mengandung metabolit sekunder seperti flavonoid, saponin, terpenoid dan steroid. Ekstrak etanol daun pacing dapat diformulasi menjadi sediaan gel dan diuji aktivitas antioksidannya. Ekstrak etanol daun pacing diekstrak dengan metoda maserasi menggunakan pelarut etanol 96% dan 70%. Ekstrak etanol daun pacing diformulasikan menjadi gel dengan cara memvariasikan 3 konsentrasi ekstrak yaitu F0 tanpa ekstrak, F1 (0,8%), F2 (1,0%) dan F3 (1,2 %). Dengan parameter uji yaitu organoleptis, uji homogenitas, uji daya sebar, uji viskositas, uji stabilitas dan uji antiosksidan menggunakan metode DPPH. Organoleptis didapatkan setiap formula setengah padat, bau khas dan warna yang berbeda-beda F0 putih, F1 coklat tua sedang, F2 Coklat tua dan F3 Coklat tua. Uji homogenitas pada setiap formula diperoleh homogen dan stabil. Uji viskositas menunjukkan hasil F0 = 2919 cP, F1 = 3185 cP, F2 = 3297 cP dan F3 = 3339 cP. Pengujian aktivitas antioksidan diperoleh nilai IC50 pada ekstrak sebesar 96,25 ppm dengan kategori kuat, F0 sebesar 321,11 ppm, F1 sebesar 155,77 ppm, F2 sebesar 151, 85 ppm dan F3 sebesar 139,04 ppm. Berdasarkan ini sediaan ekstrak etanol daun pacing yang terbaik pada F3 memiliki aktivitas antioksidan kategori sedang sehingga dapat diformulasikan menjadi sediaan gel yang stabil secara fisik.
