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. | en_US |
