Abstract :
This study aimed to determine the larvicidal power of sambiloto leaf (Adrographis paniculata) against Culex quinquefasciatus mosquitoes and as an alternative to abate chemicals (temephos). Culex quinquefasciatus larvae were used as many as 240 instar III tails. The design carried out was a completely randomized design with 6 treatments and 4 replications. The study were treated P0 (mineral water as a negative control), P1 (0.1gr / 1ltr abate), P2 ( 15% sambiloto leaf infusion), P3 (20% sambiloto leaf infusion), P4 (25% sambiloto leaf infusion), P5 (30% sambiloto leaf infusion). The Culex quinquefasciatus mosquito larvae were observed every hour for 24 hours. The data obtained were analyzed using the One way ANOVA Test and continued with the LSD (Least Significant Differences) test using the SPSS application with accuracy (P <0.01) and Probit test with LC50 and LC90 values. The results showed that the concentration of the sambiloto leaf (Adrographis paniculata) had a strong effect on larval mortality. From the One Way ANOVA test results were known that the Sig. 0.001 (p <0.01) which means that there were significant differences between treatments. Probit test results with LC50 and LC90 values in the 50% Sambiloto leaf infusion treatment have high larvicidal power. Based on the results of the study concluded that the sambiloto leaf infusion (Adrographis paniculata) has larvicidal power against Culex quinquefasciatus mosquitoes.
