PENGARUH PENAMBAHAN SURFAKTAN DALAM EKSTRAK DAUN SIRIH HUTAN (Piper aduncum L.) UNTUK MENGENDALIKAN ULAT GRAYAK (Spodoptera litura F.) PADA TANAMAN KEDELAI (Glycine max (L.) Merril)
ABSTRACT: Spodoptera litura is
main pest destroyer leaves of soybean leaves. As an alternative replacement of
synthetic insecticides is bioinsecticides by utility basicingredients from
plant that are easy find such as Piper aduncum L.. The purpose of the research
is to find out of a better surfactants concentration which can enhance the
effectiveness of Piper aduncum L. extract below 10% which is the concentration
75 g/l of water to control S. litura of soybean. The research was conducted at
the Laboratory of Plant Pests, Faculty of Agriculture, University ofRiau from
March to May 2016. The Research was conducted experimentally by using
completely randomized design (CRD), which consists of 4 treatments, whereeach
treatments was replicated 4 times to obtain 16 experimental units. The treatments
used in the research were 0 %, 0.025%, 0.037% and 0.050% concentration of
surfactants given as the extract of Piper aduncum L. concentration of 75 g/l
water. The result showed the addition of several concentrations of surfactants
hasn’t been able to increase the effectiveness of the concentration of ekstract
Piper aduncum L. under 10% that is concentration of 75 g/l water as
bioinsecticides in controlling the S. litura. But the addition of surfactants
on the concentration of 0.05% (recommended dose) can increase the death of S.
litura as big as to 7.5%.
