Introduction: Dengue Fever Dengue fever (DHF) has developed into a major health problem for Indonesian society. Vector control to stop the chain of transmission of dengue fever is one way to prevent dengue fever. One effective way to control dengue fever is to control larvae using insecticides. Continuous use of insecticides can cause side effects that are harmful to the environment. Therefore, natural insecticides are needed by utilizing materials around us that contain substances as insecticides, one of which is jasmine flowers (Jasminum sambac). Method: This study aims to determine the effect of jasmine flower extract on Aedes aegypti larvae with concentrations of 10%, 15%, 20%, 25% with contact times of 5 minutes, 10 minutes, 15 minutes, 20 minutes, 25 minutes, 30 minutes, 35 minutes, 40 minutes,45 minutes,50 minutes,55 minutes,60 minutes. This type of research is an experiment with a completely randomized plan. How to make extraction by ceration using 96% ethanol. The samples are third instar Aedes aegypti larvae. Results: The results of this research showed that the concentration that caused a 50% knockdown effect based on estimates was at a concentration of 14,019%. The results of statistical analysis with anova p=0.05 showed a significant effect of the interaction of concentration and contact time (p=0.19) on the death of Aedes aegypti larvae. Conclusion: This research has proven that jasmine flower extract (jasminum sambac) is effective as a larvicide. From the results of the probit analysis, it was found that the concentration that caused a 50% knockdown effect based on estimates was a concentration of 14,019%.
