Wibowo TN, Darukutni, Handayani SS. 2010. The mortality effect of castor bean (Ricinus communis) extract on Aedes aegypti larvae. Biofarmasi 8: 77-81. The aim of this research was to determine the mortality effect of Ricinus communis L. extract on Aedes aegypti L. larvae. This research was an laboratory experimental, with a post-test only controlled group design, and used 750 larvae Instar III of A. aegypti L. that divided into 6 groups (control group, and five treatment groups consisted of 0.10% extract, 0.25% extract, 0.50% extract, 0.75% extract and 1% extract). The sampling technical was a purposive sampling method. The larvae were put into 25 ml experimental liquid for 24 hours. The observation was counting a number of dead larvae in 24 hours. Data were analyzed with one-way ANOVA test continued with Least Significant Difference (LSD) using SPSS for Windows Release statistically with a significance level p<0.05 then continued with a probit analysis. There were 0 larva death at negative control, 23.8 (95%) larvae death at 0.10% extract concentration, 24.6 (98%) larvae death at 0.25% extract concentration, 25.0 (100%) larvae death at 0.50%, 0.75% and 1.00% extract concentration. There was a significant difference in larvae death of A. aegypti in all groups. The LC50 of R. communis extract was 0.01036% (103.6 ppm), therefore it could be concluded that R. communis extract had a mortality effect to A. aegypti larvae.
