Larvicidal Activity of Ethanol Extract of Bintaro Leaf (Cerberaodollam Gaertn.) against Aedesaegypti Larvae

Abstract
Bintaro leaves (CerberaodollamGaertn.) contain secondary metabolite compounds consisting of flavanoids, steroids, saponins, and tannins that have the potential as larvicides. This study aims to determine the mortality rate of Aedes aegypti larvae after administration of ethanol extracts indicated by the LC50 value. The extract was obtained using the maceration method. The yield of bintaro leaf extract was 10.12%. This study used 150 mosquito larvae (Aedes aegypti) instar III. Tests were carried out with test solutions made with 5 concentrations (100 ppm, 200 ppm, 400 ppm, 800 ppm, and 1000 ppm), positive control using abate, and negative control of aqua-dest. Observations were made every 24 hours for 4 days then the data was analyzed using Probit analysis to determine the LC50 value. The results of larvicidal testing showed that ethanol extract of Bintaro leaves had the best larvicidal activity on day 3 with an LC50 value of 354.81 µg/mL and on day 4 with an LC50 value of 316.22 µg/mL.
