The Effectiveness of Piper betel L. Leaf Extract as a Natural Electric Mosquito

Mosquitoes are known as insects that interfere with comfort. Mosquitoes are also known as vectors or transmitters of several types of dangerous and deadly diseases for humans, one of which is dengue fever. Therefore, an alternative is needed to reduce this species. The alternative that can be done is by providing vegetable insecticides. Betel leaf has the potential to be used as a base for making plant-based insecticides that are environmentally friendly because they contain chemical compounds in the form of phenols and derivatives such as chavikol and eugenol, alkaloids, tannins, flavonoids, saponins and essential oils. This study aims to determine the concentration of betel leaf extract (Piper betel L.) which is effective for killing mosquitoes. This study used an experimental method using a completely randomized design (CRD) with 6 treatments and 4 replications, namely KN as negative control group, KP as control positive (100% HIT brand liquid), P1 25% extract, P2 50% extract, P3 75% extract, and P4 100% extract. The number of dead mosquitoes (mortality) were observed after 1 hour of treatment. Data were analyzed using variance analysis (ANAVA). The results of this study were the administration of various concentrations of betel leaf extract (Piper betel L.) significantly (p <0.05) to kill mosquitoes. The greatest frequency of mosquito mortality was found at the P4, the highest extract concentration. The conclusion of this study is that betel leaf extract for 1 hour had a significant effect on mosquito mortality.
