Toxic test of ethanolic extract of lavender (Lavandula angustifolia) leaf on mortality of Aedes aegypti mosquito larvae as vector of dengue hemorrhagic fever has been completed. The aim of the study was to determine the effective concentration of lavender (Lavandula angustifolia) leaf ethanol extract against the mortality of Aedes aegypti and LC50 mosquitoes for 24 hours. This study used a completely randomized design with 5 extract treatments, namely: 10ppm; 50ppm; 100ppm; 500ppm and 1000ppm and 1 control group with 3 replications. The results of the study were analyzed using one-way analysis of variance. and continued with the BNT test at a significance level of 0.05. The results showed that the ethanolic extract of lavender (Lavandula angustifolia) leaves was toxic to the larvae of the Aeders aegypti mosquito, which was indicated by the increasing number of larval mortality. Based on the test results, the concentration of 500 ppm lavender leaf ethanol extract was able to kill 100% of mosquitoes, and the effective concentration to kill 50% of test mosquito larvae was 87.0285 ppm. The ethanol extract of lavender (Lavandula angustifolia) leaves has the potential to be developed as a biolarvicide for the Aedes aegypti mosquito vector of dengue hemorrhagic fever.
