Optimizing of maseration with ethanol and water solvents against the toxicity of extract of wuluh starfruit (Averrhoa bilimbi L.) in controlling larva of Aedes aegypti

Abstract:
The control of Aedes sp. mosquito need to be conducted appropriately and environmental friendly. Wuluh starfruit (Aaverrhoa bilimbi l.) contains alkaloids, saponins, and flavonoids, can be used as insecticides. In its usual use through maceration, good maceration will produce good toxicity as well as the death of Aedes aegypti larvae. In this study an optimization of the composition of ethanol and water was carried out as a dancer in the maceration process, on fruit and tested for toxicity to Aedes mosquito larvae. Aim: To determine the toxicity of carambola fruit in killing Aedes aegypti larvae using the difference maceration method on the ratio of ethanol-water dancers (100% -0%, 75% -25%, 50% -50%, 25% -75% and 0% -100%).
Materials and Methods: This was an experimental study, the object of the research was the extract of Wuluh starfruit and the difference in maceration on the spread between ethanol and water. Mortality data were analyzed by ANOVA, if there was a real effect of the treatment, it was followed by LSD test, and phytochemical analysis of Wuluh starfruit.
Results and Discussions: The results obtained by extract of carambola fruit (Averrhoa bilimbi l.) The highest number of dead mosquitoes was obtained through an extraction process with the composition of ethanol and water solvents with a ratio of 100%: 0% with an average number of deaths of 25 (100%), significant influence on the average mortality of Aedes aegypti larvae from various variations of ethanol and water solvents in the extraction of fruit and wuluh starfruit leaves (Averrhoa bilimbi l.).
