Papaya plants contain many substances called papain, papain protease effect can kill larvae of Aedes aegypti. This study aimed to determine the effect of papaya leaves extracts (Carica papaya Linn) against Aedes aegypti larvae mortality. The research method was a quasi-experimental research design with Non-Equivalent Control Group. The concentration levels were 6.25%, 12.5%, 25%, 50%, 100%, and controls (CMC-Na) with 4 times replication. The Probit Analysis test results showed Lethal concentration (LC50) of papaya leaves extract (Carica papaya Linn) against Aedes aegypti larvae mortality was to 24.46% and the effective time is 22 hours. It is concluded that any different concentrations of papaya (Carica papaya Linn) leaves extract have effect on Aedes aegypti larvae mortality (p <0.05), the time depth of papaya leaves extract have effect on Aedes aegypti larvae mortality (p <0.05), the average number of Aedes aegypti larvae mortality for 24-hours in each concentration are concentration of 6.25% as much as 4.75 larvae, 12.5% concentration as much as 8 larvae, a concentration of 25% as much as 12 larvae, 50% concentration of 14.5 larvae, concentration 100% as much as 19 larvae and control as much as 1.25 larvae. The recommended suggestion is to conduct a phytochemical test to determine the active substances contained in papaya (Carica papaya Linn) leaves extract and to know the concentration of active substances in the extract.
