Abstract

Permot (Passiflora foetida Linn.) leaf has so many benefit as a herbal medicine. Larvaside is one of its utility. Since Permot leaf has some active component, saponin, flavanoid, alkaloid, so that Permot leaf has larvaside ability. The purpose of this experiment to know larvaside ability of Permot leaf ethanol extract which gain from the corelation between concentration and the rate of larva mortality in 24 hours. 480 samples of Cx. pipiens fatigans (Linn.) larvae instar IV are used for this experiment, divided in to six groups of experiment, which were 100 ml aquadest (control), 0.1 % PEG (control), Permot leaf ethanol extract with concentration 500 ppm, 1000 ppm, 1500 ppm, 2000 ppm. Each plastic glass was contained 20 larvas and replicated four times. During the experimentation, larvae were fed with catfish food. The result of experiment are from observation of the mortalities in 24 hours. By the One-Way ANOVA test, resulted p value = 0.000. By the Pearson Corelation test, resulted p value = 0.000 and corelation coeficient = 0.987. By Linier Regression test, resulted A Constant value = 2.5, B extract concentrate (%) value = 0.048 and regression formula is Y= 2.5+ 0.048X. From this study it can be concluded that Permot leaf ethanol extract have larvaside ability to Cx. pipiens fatigans (Linn.) larvae instar IV and resulted LC50 is 999 ppm concentrate also LC95 is 1927 ppm concentrate.
