Dengue Hemorrhagic Fever is an acute febrile disease caused by the dengue virus which enters the human bloodstream through mosquito bites from the genus Aedes. Aedes aegypti and Aedes albopictus are the main vectors of dengue transmission. DHF prevention is carried out by breaking the chain of transmission. Biological insecticides have the potential to control vectors. This study found out the effectiveness of young areca nut (Areca catechu L.) extract on the mortality of Aedes sp. Mosquito larvae. This research method is true experiment with Post Test Only Control Group Design. The study showed that the average percentage of larval mortality at a concentration of 2000 ppm was 39.2%, a concentration of 3000 ppm was 72%, a concentration of 4000 ppm was 84.8% and a concentration of 5000 ppm was 100%. The results P-ISSN: 2338-7033 E-ISSN: 2722-0613 37 of the One Way Anova test obtained p-value = 0.000 (p = <0.05) so that it was stated that there was a significant difference in the number of larvae that died at various concentrations and the results of the Bonferroni Test showed that the most effective concentration against the death of Aedes sp mosquito larvae was at a concentration of 5000 ppm. It is hoped that further research will find a more applicable young areca fruit formulation so that its use is easier in the community.
