Uji Efektivitas Ekstrak Daun Sirih Hijau (Piper Betle L), Daun Sirih Merah (Piper Crocatum) dan Daun Sirih Kuning (Piper Betle) terhadap Mortalitas Larva Nyamuk Aedes Aegypti

ABSTRACT The Aedes aegypti mosquito is the main vector of DHF (Dengue Hemorrhagic Fever). In the city of Surabaya in 2019, there were 277 cases of dengue fever. Control using chemical insecticides can create resistance for larvae so that other methods can be used, namely herbal insecticides on green betel leaves, red betel leaves and yellow betel leaves which contain compounds such as essential oils, alkaloids, flavonoids, saponins and tannins which are toxic and can affect the digestive system. and nervous system in Aedes aegypti larvae. The purpose of this study was to determine the effectiveness of green betel leaf extract (Piper betle L), red betel leaf (Piper crocatum) and yellow betel leaf (Piper betle) as natural insecticides against Aedes aegypti larvae. This research was conducted at the Entomology Laboratory of the East Java Provincial Health Office in May 2022. The data collection technique was experimental. In this study there were 5 treatment groups with concentrations of 0.1%, 0.5% and 1% and there were positive control groups (abate) and negative control groups, each treatment had 5 replications. Each test contained 20 instar III Aedes aegypti larvae. With the duration of exposure for 60, 120, 180, 240, 300, 360, 420, 480, 540, 1440. The results of this study indicate that the greater the concentration and duration of exposure, the more mortality of mosquito larvae. The results of the data analysis of this study showed that they were not normally distributed and were not homogeneous, so the Kruskal-Wallis test gave a p value (0.05) then there is no difference, if p (0,05) maka tidak ada perbedaan, apabila p < (0,05) maka adanya perbedaan pada setiap konsentrasi ekstrak terhadap mortalitas larva.
