Uji Beberapa Konsentrasi Ekstrak Tepung Akar Tuba (Derris Elliptica (Roxb.) Benth) Mengendalikan Hama Penghisap Polong (Riptortus Linearis F.) Pada Tanaman Kedelai (Glycine Max (L.) Meriill)

ABSTRACT
Pod-sucking pest (Riptortus linearis) is the main pests of soybean plant.
Safe and environmentally friendly control is the use of botanical insecticides from
tuba plant (Derris elliptica). This study aims to obtain the effective concentration
of tuba root extract powder (Derris elliptica) to control pod-sucking pests
(Riptortus linearis) in soybean plant. This research was conducted at the Plant
Pest Laboratory, Faculty of Agriculture, Riau University and Jalan Rajawali Sakti,
Panam, Pekanbaru. The research was conducted with an experimental method
using a complete randomized design (CRD) consisting of 6 treatments and 4
replications. Concentration treatment of tuba root extract powder given was the
concentration of tuba root extract powder of 0 g.l-1 water, 20 g.l-1 water, 40 g.l-1
water, 60 g.l-1 water, 80 g.l-1 water, and 100 g.l-1 water. The parameters observed
were the initial time of death, lethal time 50, daily mortality, total mortality, and
changes in behavior and morphology. The results present that the concentration of
100 gl-1 water was the most effective concentration with the fastest initial death at
3,75 hours, the fastest LT50 at 47,25 hours, the percentage of daily mortality was
32,5% on the first day after application, and a total mortality of 92,50 % during 90
hours of observation.
Key words: Derris elliptica, Riptortus linearis, botanical insecticide,
concentration.
