dc.description.abstract | Armyworm (Spodoptera litura F.) is a leaf-eating pest causes the loss of crops from 85% until causing
crop failure. Alternative pest control and to reduce the negative impact of synthetic pesticides include
using botanical pesticide. Getih-getihan plant (Rivina humilis L.) is one of the plants having potency as
a botanical pesticide. Based on the description, this study was conducted to determine LC50 value by
using probit analysis and analysis of an extract of Rivina humilis L. leaves on the mortality of Spodoptera
litura
F.
using
ANOVA
test.
