Uji Beberapa Konsentrasi Ekstrak Umbi Gadung (Dioscorea Hispida Dennst) Terhadap Hama Keong Mas (Pomacea Canaliculata L.) Pada Padi Sawah (Oryza Sativa L.)

ABSTRACT
Riau is a lowland rice producing province. One of the pests that can reduce
the productivity of lowland rice is the golden snail (Pomacea canaliculata L.). The
solution for controlling pests of golden snail (P.canaliculata L.).Uses
environmentally friendly control techniques, namely botanical pesticides of
gadung tubers. This study aims to obtain a concentration of the extract of gadung
tuber flour (Dioscorea hispida Dennst) which is effevtive in controlled the attack
of golden snails (P. canaliculata L.) in lowland rice plants. This research was
conducted experimentally using completely randomized design (CRD) consisting
of five treatments and four replications, in order to obtain 20 experimental units.
The treatments consisted of concentrations of gadung tubers extract, namely 0 g.l-
1,25 g.l-1,50 g.l-1, 75 g.l-1, and 100 g.l-1. Observations included the initialdst time
to snail death, lethal time 50 (LT50), daily,total mortality and changes in behavior
changes. The results showed that the application of 100 g.l-1 concentration of
gadung tuber Extract treatment caused the highest total mortality of golden snails
(P. canaliculata L.) of 74.99 %, but it was not yet effective in controlling the
golden snail pest because it was not able to kill the golden snail above 80 %.
