PENGARUH VARIASI KONSENTRASI EKSTRAK SERAI (ANDROPOGON NARDUS) TERHADAP MORTALITAS HAMA KEONG MAS (POMACEACANICULATA L.)
ABSTRACT: Snails (Pomaceae
canaliculata L) or often referred to as snail mulberry is one type of
freshwater snail that comes from the Americas. The spread of snails (Pomaceae
canaliculata L.) in Indonesia the spread widening due to breeding very fast.
Besides, many snails are farmed in ponds so many move to the rice fields.
Potential snails can cause crop damage ranges from 10-40%. The aim of this
study was to determine the concentration of extract of lemon grass (Andropogon
nardus) most appropriate for mortalty pest snails (Pomacea caniculata L.). This
study was conducted in July to September 2014 in Biology Laboratorium State
Islamic Institute (IAIN) Raden Intan Lampung. This type of research is
experimental. The method used in the study is the method of full randomized
design (CRD) with three repetitions each cup contains 12 heads snails. The
concentration of treatment were 0% (as a control), 2%, 3%, 4%, 5%. Based on the
results of the study showed that:The concentration of the most effective in
killing pests snails Pomacea caniculata L is 5%, which is able to kill 100% of
pest snails Pomacea caniculata L for 24 hours. Sitronela compounds have the
nature of a contact poison that can cause death due to loss of fluid
continuously.
