Introduction: Aedes aegypty is one of mosquito species, especially Aedes genus which can cause dengue fever to humans. This species acts as dengue virus vector through the bite of mosquitoes which enters the human bloodstream. Salam leaf extract is well known for its various functions, one of them is to fight against Aedes aegypti L. larvae.Purpose: This research aims to know the larvicidal activity of Syzigium polyanthum W. leaf extract against Aedes aegepty L larvae. Materials and methods: This study is an experimental research with Posttest Only Control Group Design method using ANOVA test. The samples were Aedes aegypti L. larvae instar III and Syzigium polyanthum W. extract. Maceration method was used in the extraction process. The dosages of the extract tested were 0% (control), 0.25%, 0.5%, 0.75%, and 1%.Results: The results showed there were no larval mortality in 0% concentration (control). The percentage of larval mortality was on the average of 18.68% in 0.25%, 32% in 0.5%, 54.68% in 0.75%, 78% in 1% concentration. The Analysis of Variance obtained from F count = 1414.86 which was bigger than F table = 2.75, so H0 was rejected. The analysis of Reed and Muench obtained was LC50 = 6576.68 ppm or around 0.66 %. Conclusion: Based on that result, it can be concluded that the extract of salam leaf is potential as a larvacide on Aedes aegypti L. larvae
