UJI LARVASIDA NYAMUK (AEDES AEGYPTI) DARI ASCIDIAN (DIDEMNUM MOLLE)
ABSTRACT: Dengue haemorrhagie
fever is one of the disease which caused by dengue virus. It spreads out by
mosquito Aedes aegypti as the vector. To date, people use abate as the
larvacidal. Yet it causes the negative
effects, such as bad odor, rustiness of the water container and resistency
either to the larvae or to the living environment if continue using it. The
objective of the research was to examine the larvacidal activity of Didemnum
molle extract against A. aegypti larvae. The sample was extracted with methanol
to give methanolic extract which was further partitioned with ethyl acetate,
hexane, and chloroform to yield three fractions of ethyl acetate, hexane, and
chloroform. Methanolic extract and the three fractions were tested against the
A. aegypti larvae instar III for several concentrations. Abate and tap water
were used as controls. The result exhibited that Didemnum molle extracts
contain or produce larvacidae substances against A. aegypti larvae. They are
approved by the data of methanolic extract and the 3 fractions which are more
powerful than abate, particularly hexane. However it still needs to be purified
to obtain single active compound.
