Perbandingan Ekstrak Batang Sereh (Cymbopogon Citratus) dan Citronella Oil Sebagai Repelen terhadap Nyamuk Culex Sp Dewasa Betina
Abstract: Culex is known as
the vector transmitter of filariasis and encephalitis, and to control its
spread, repellent is commonly used. DEET has been widely used and proven as an
effective repellent; however, it also has many side effects that may be harmful
tothe human health. Accordingly, people tend to prefer using repellents made of
natural herbs, such as lemon grass or citronella oil,which have been proven effective.
This research was aimed to compare the effectiveness of lemon grass stem
extract, at various concentrations, against citronella oil. This was a real
comparative, prospective experimental study using complete randomized design.
Seven hundred and fifty Culex sp. mosquitoes were divided into 5 treatment groups;
3 groups were treated with lemon grass stem extract at 50% (EBS50), 75% (EBS75),
and 100% (EBS100) concentration; the negative control group was treated with
aquadest and the positive control group was treated with citronella oil. An
observation was conducted to find out the number of mosquitoes that moved to
the opposite side of the glass box. The data were analyzed using one-way ANOVA,
followed by Tukey HSD test with α= 0.01. The result showed that citronella oil
had the highest effectivity, followed by EBS100, EBS75 and EBS50(p =
0.000-0.005). The conclusion is that lemon grass stem extract is a Culex
mosquito repellent which is less effective than citronella oil.
