UJI EFEKTIVITAS DAYA TOLAK UAP EKSTRAK KULIT JERUK LEMON (CITRUS LIMON, SWINGLE) TERHADAP NYAMUK AEDES AEGYPTI (DIPTERA : CULICIDAE)

Abstract

Citrus reticulata is a plant that is believed to be used as a repellent against mosquito bites. The plant contains several substances that repel mosquitoes. Although quite effective, this type of mosquito repellent is risky because it is presence of active substances in the form of chemical content. Almost all anti-mosquito lotions circulating in Indonesia contain active ingredient DEET (Diethyl toluamide) which is a toxic synthetic chemical when in a concentration of 10-15%. This research is quasi-experimental which aims to find out the ability of citrus reticulata peel extract vapor to repel Aedes aegypti mosquitoes. The research was conducted in the laboratory of Integrated Poltekkes Kemenkes Medan. Starting from May 2018 to October 2018. Research material in the form of orange peel (simplisia) obtained from the market of Fruit Brastagi Karo Regency. Simplisia soaked in organic solvents (alcohol 76%) for 3-5 days to get maserate, and filtered using a fine gauze sieve to get citrus reticulata filtrate. The application process to find out its repulsion, using Aedes mosquito test material. adult aegypti, which is carried out rearing for 5 weeks. From the results 2 times 100% (55.52%) and 75% (35.83%). Using electric mosquito repellent, a combination of both comparisons 1 and 2 adult mosquito displacement by 62%. That difference between comparison and  test difference is quite small, which is 6.48% at concentration of filtrate 100%, while at a concentration of 75%  difference is 26.17%. Test results based on percentage displacement can be said that a dilution of 100%, 75%, 50%.
