MEMPELAJARI BAGIAN TANAMAN DAN KONSENTRASI EKSTRAK KUNCI PEPET (Kaempferia rotunda L) YANG MEMPUNYAI SIFAT REPELAN NYAMUK Aedes aegypti

Abstract

The research purpose were to find out the part of plantextract and an extract concentration of Narrow-leaf peacockginger as repellant agent to Aedes aegypti mosquito.The research method used the completed randomizeddesign with two factors in factorial experimental. The bothfactors were 1) the plant part to enclose a stalk-root andtuber; 2) an extract concentration with 5 levels to enclose 0,5, 10, 15, 20% so that there were 10 combination treatmentsthat to be replicated 5 times.The results of the research showed that the tuber andstalk-root extracts of Narrow-leaf peacock ginger had anatural repellant constituent. Narrow-leaf peacock gingertuber extract in 15 and 20% concentration had the highest ofrepellant capacity or to kill mosquito. The longer applicationof the extract decreased the repellant capacity, especially thatto be extracted of the stalk-root and tuber in consentrationapplication of 5 and 10%.
