Star fruit extract (Averrhoa carambola L) is potential as a natural larvicides because it contains chemical compounds of flavonoids, alkaloids, saponins. This study aims to determine the larvacidal activity of star fruitextract to Aedes aegypti larvae and LC50 value after 24 hours exposure. This study used concentration with 1.5%, 2%, 2.5%, 3%, 3.5% and 1 negative control using tap water and 1 positive control using 0.01% temefos. This study was post test only with control group design, total samples is 525 larvae from third stage instar larvae of Aedes aegypti. The mortality larvae will be calculated after 24 hours. The results of the study showed the percent mortality at concentrations of 1.5%, 2%, 2.5%, 3%, 3.5% Aedes aegypti larvae were respectively 0; 10.68; 21,36,30,68; 54,68; 61,36. The result of Annova test obtained P <0,05 meaning that there is significant difference between death rate of Aedes aegypti larvae with various concentration of star fruit extract (Averrhoa carambola L ) given. The LC50 value of the probit test for Aedes aegypti larvae is 3.035%. It can be concluded that the star fruit extract (Averrhoa carambola L) can kill Aedes aegypti larvae.
