Abstract

LIA ANDRIANI TARIGAN:The Effect of GivingVariation ofConcentrationKecombrangFlowers Extract(Etlingera elatiorJackR. M.Sm) asNatural Insectiside AgainstAedessppSupervised by RIDWANDTY BATUBARA and SUMARDI. Aedes spphave been public health problems, such as dengue, yellow fever, chikungunya and others. One way to eradicate mosquitoes that most commonly used is to use insecticides. The use of chemical insecticides aimed at killing the adult mosquitous also poses its own problems is the emergence of resistance of mosquitoes and toxic effects in humans. Therefore, the necessary existence of alternative insecticides that are safer for the environment. One of that is considered as natural insecticide is kecombrang (Etlingera elatiorJackR. M. Sm) flowers. The purpose of this research is to prove that kecombrang flowers extract has potential as an insecticide againstA. spp. This research is a laboratorial experimental research with true experimental post test only control group design.The repetitions were done three times with four types of solutions which are, control (aquades), and kecombrang extracts 3%, 4.5%, 6%. Every repetitions were perceived at 3 intervals 10 minutes, 20 minutes , 30 minutes. Mortality of A. spp seen after 24th hours. From the One Way ANOVA test found significant differences in each flower extract concentration effect kecombrang Based on the result of this research, it is conclude that extract of kecombrang flowers have a potential as an insecticide againstA. spp.and effective in 4.5 % concentrate.
