Abstract

There are some plants that have a distinctive odor and which smell is not liked by mosquitoes.
one of the plants that is easily obtained and doubly beneficial for humans is pandan wangi
leaves (pandanus amaryllifolius oxb) and tamarind leaves. The purpose of this study was to
determine the effect of acidic extract of tamarind leaves on Aedes aegypti mosquitoes at
various concentrations and the effect of persistence (length of time) of tamarind leaf extract
applied on the test of Aedes aegypti mosquito, the method used is the experimental method,
which is testing pandan wangi leaf extract and tamarind leaves with various concentrations on
mosquito control. So the design used is a Completely Randomized Design (CRD). The results
showed that essential oils of pandan wangi leaves and tamarind leaves had an effect on the
repellent power of Aedes aegypti mosquitoes at 07.00-10.00 WIB and at 15.00-17.00 WIB. At
the observations at 07.00-10.00 WIB, giving the most fragrant pandan leaves oil at
concentrations of 50% and 90% with expulsion power of 89.7% and 91.3%. Whereas in the
observation at 15.00-17.00 WIB the use of essential oils of pandan wangi leaves expelled the
mosquitoes at a concentration of 70% with an expulsion of 89.3%, and the mosquito acid of
the mosquitoes which was displaced by 89%. The next suggestion is to use other plants
besides pandan wangi and tamarind leaves which are not widely used to control mosquitoes,
especially mosquitoes that can cause diseases such as Aedes aegypti.
