Household insecticides were sold freely in the market and its use in society which wasn’t observed to be more to accelerate the occurrence of resistance. This has led to the development of alternatives to use natural ingredients. Fragrant pandan (Pandanus amaryllifolius Roxb.) leaves contain saponins and polyphenols that are as larvacide. The aim of this study was to examine the effectiveness of fragrant pandan (Pandanus amaryllifolius Roxb.) leaves extract to kill mosquito larvae of Aedes aegypti. This research was an experimental research with posttest only control group design where the objects were divided into two groups: control group and treatment group. The samples were 25 larvae on each group, and it was repeated four times. So the total of samples were 700 Aedes aegypti larvae. The results of this research showed that at 0% (control) concentration of fragrant pandan leave extract could kill 0 larvae of Aedes aegypti, 0.5% concentration could kill 19,5 (20) larvae (78%), 0.6% concentration could kill 20.75 (21) larvae (83%), 0.7% concentration could kill 23 larvae (92 %), 0.8% concentration could kill 24 larvae (96%), 0.9% concentration could kill 25 larvae (100%), and 1.0% concentration could kill 25 larvae (100%). Based on anova test analysis, it could be concluded that there was an effect of fragrant pandan leave extract against Aedes aegypti larvae mortality with a significant p value of 0.000 (p <0.01). Fragrant pandan (Pandanus amaryllifolius Roxb.) leave extract at 0.9% concentration was the most effective concentration to kill mosquito larvae of Aedes aegypti.
