ANALISIS POTENSI EKSTRAK DAUN CENGKEH (Syzygium aromaticum) SEBAGAI REPELEN NYAMUK

Abstract

Dengue hemorrhagic fever (DHF) is an infectious disease transmitted by infected Aedes aegypti and Ae. albopictus. DHF cases increased 30-fold with geographic expansion to new countries and, in this decade, from urban to rural locations. Therefore, it is necessary to make efforts to prevent transmission, one of which is by using an anti-mosquito repellent. This study aimed to determine the effectiveness of clove leaf extract (Syzygium Aromaticum) as a repellent for Aedes aegypti mosquito spray. Experiments using 100 Ae. aegypti adults (aged 2-5 days) developed at the Baturaja Lokalitbang. The test was conducted on five probands (volunteers aged 18-25 years) who were exposed to clove leaf extract at five concentrations (3%, 5%, 7%, 9%, and 12%), for six hours. Data was collected every hour, then analyzed by ANOVA test. The study found that clove leaf extract can repel mosquitoes significantly (p-value = 0.010). The lowest average of mosquitoes perched is 1.5, at a concentration of 12%. The trend (six hours) is a maximum of 2.5 birds. However, the protection power only reached 43.7%, so it has not been included in the effective category (80%). The study has proven that clove leaf extract (Syzygium aromaticum) with spray application can be an alternative to Ae. aegypti mosquito repellent. Further research is needed to get an effective concentration.

Potential of Noni Leaf Extract (Morinda citrifolia L.) As Aedes aegypti Mosquito Repellent

“…38 The higher the concentration of the extract used, the lower the average number of mosquito habitats. 13 With concentrations ranging from 12.5% to 25%, research shows that the noni leaf extract has promising potential as a natural repellent. The optimal concentration of 37.5% indicates higher efficacy, making it an attractive alternative to protect against insect bites.…”

“…11,12 Repellents are substances used to repel insects and other animals and prevent their bites and stings on humans. 13 The noni plant (Morinda citrifolia L.) can be used as a repellent. Its leaves contain alkaloids, saponins, flavonoids, tannins, polyphenols, ethanol and glycosides, which can be used as a repellent.…”
