TEST OF THE EXTRACT EFFECTIVENESS OF RED BETEL LEAF (PIPER CROCATUM RUIZ AND PAV) AS ELECTRICMATE METHOD (PLATE) TO AEDES AEGYPTI MOSQUITOAlkausyari Aziz, Betty Nia Rulen and Eliza Fitria
Red betel leaves (Piper crocatum Ruiz and Pav) which contain chemical compounds such as flavonoids, polyphenolic compound alkaloids, tannins, and essential oils, can be used as vegetable insecticides extracted by the electric mat (plate) method as an innovation of burning mosquito repellent. This study aimed to determine the effectiveness of red betel leaf extract (Piper crocatum Ruiz and Pav) as a botanical insecticide. Red betel leaf extract (Piper crocatum Ruiz & Pav) has a concentration of 1.25%, 2.5%, 5%, and 10%. It uses univariate and bivariate tests such as the probit test to determine LC50 and LC90, the One Way Anova test to know the concentration that has the potential for bioinsecticide. The results showed that from the univariate test, the average number of mosquitoes that died in the treatment group was 1.25% (26 heads), 2.5% (24 animals), 5% (15 animals), and 10% (20 animals). The data normality test results showed that the data were normally distributed (> 0.05) from 4 concentrations. The One Way ANOVA test results showed no difference (sig 0.541) in the increase in mortality in Aedes aegypti mosquitoes in each concentration. Based on this study, the red betel leaf extract proved to be effective at a concentration of 1.25% with a value of 43.3% against Aedes aegypti mosquitoes and 24 hours of contact time with LC50 at a concentration of 9.901 ppm and LC90 19.524 ppm. In conclusion, red betel leaf as an environmentally friendly bioinsecticide can be used as an alternative to chemical insecticides.
