UJI AKTIVITAS LARVASIDA EKSTRAK TERPURIFIKASI DAGING BUAH MIMBA (Azadirachta indica A. Juss.) ASAL PULAU LOMBOK TERHADAP Aedes aegypti
Abstrak: Neem (Azadirachta
indica A.Juss.) Is a plant that has medicinal benefits as malaria, antitukak
stomach and is also can used as natural insecticides, fungicides, larvicides
and antifertility. This Research aims to know the mortality rate of larvae of
Aedes aegypti with LC50 values indicated. Neem fruit plucked from a tree lombok
island.neem. Extracts obtained by maceration solvent with the masceration
methanol. Retrieved rendamen extract as much as 25,17%, then purified with
n-hexane solvent. Larvasida test used 180 larvae of Aedes aegypti first instar
III. Test solutions were made in 4 concentration, positive control using powder
Abate® (Themephos), and a negative control. Observations were made after 24
hours of treatment . Aedes aegypti larval mortality analyzed with probid
analysis to know LC50 and obtained phytochemical components contained in the
methanol extracts were saponins and tannins. LC50 obtained from the methanol
extract of neem fruit flesh is 1817,18 ± 1,075 µg/ml. This shows the methanol
extract of neem fruit flesh (Azadirachta indica A.Juss.) Does not have the
effect toxicity against larvae of Aedes aegypti indicated by LC50 > 1000
ppm.
