Abstract

Abstract: White Turmeric Larvicides (Curcuma zedoaria) Against Death of Aedes sp. Larvae. Dengue Hemorrhagic Fever is a disease transmitted through mosquito bites from the genus Aedes sp. Chemical control is carried out by killing larvae using abate but can cause resistance from the target organism, to solve this problem by using natural insecticides, namely white turmeric. This study aims to determine the effectiveness of white turmeric larvae (Curcuma zedoaria) on the death of Aedes sp. Larvae. The type of research used is pure experiment. In this study researchers can control the course of the experiment. The sample used was 25 larvae which were put into container boxes with various concentrations and length of contact time. The results of the analysis of concentration variations showed sig <α (0.247> 0.05). The duration of contact showed sig <α (0.004 <0.05). The concentration variation has no effect while the contact time has an influence on the mortality of Aedes sp. Larvae. The LC50 value at 72 hours contact time is 0.25% and TU 400 value. The effectiveness of white turmeric larvacide is at a concentration of 0.6% which can kill 88% of target insects / animals. Suggestion, to reduce the aroma of white turmeric as larvacide. Need to test other mosquito larvae. At the contact time of 48 hours with a concentration of 0.6% ± 1 teaspoon the juice of white turmeric rhizome in 1 liter of water was said to be effective.
