Abstract
One of the plants considered to have insecticidal potential is kecombrang (Etlingera elatior). The chemical content contained in kecombrang is alkaloids, flavonoids, saponins, and tannis. The purpose of this study was to determine the differences in activity of the fruit extracts of Etlingera elatior and Etlingera hemisphaerica as larvacides of Aedes aegypti. The method used is a comparative experimental method. The sample population in this study were third instar larvae of Aedes aegypi using two groups, namely Etlingera elatior fruit extract and Etlingera hemisphaerica fruit extract (concentration 0.25%, 0.50%, 0.75% respectively), 1%, 1,25%). Data analysis in this study was carried out by calculating larval mortality and calculating the LC50 value, from each group with 24 hours of observation. The data is presented in the form of numbers, tables, and diagrams which are analyzed statistically. The results of this study two groups of fruit extracts Etlingera elatior and Etlingera hemisphaerica had larvicidal activity against Aedes aegypti. The results of the average larval mortality showed that concentrations of 0.5%, 0.75%, 1%, and 1.25% had activity that could kill 100% of the test larvae for 24 hours. has an LC50 value of 0.238% and the fruit extract of Etlingera elatior has an LC50 value of 0.216%. Etlingera hemisphaerica fruit extract is better because it has a higher mortality percentage than Etlingera elatior fruit extract. Keywords :Etlingera elatior, Etlingera hemisphaerica, Larvicide
