UJI BEBERAPA KONSENTRASI EKSTRAK DAUN BINTARO (Cerbera manghas L.) SEBAGAI PESTISIDA NABATI UNTUK MENGENDALIKAN HAMA ULAT JENGKAL (Plusia sp.) PADA TREMBESI (Samanea saman (Jacq.)Merr.)
Abstract: Samanea saman tree
species that have great ability to absorb carbon dioxide from the air. Samanea
samangrowthnot be separated from the problem of pests and diseases. Pests that
attack Samanea samanand often result in losses that Plusia sp. Indonesia has a very
diverse flora, contains quite a lot of kinds of plants which are sources of
pesticides that can be used for pest control. The use ofCerbera manghasleaf
extractas a botanical pesticide for controlling Plusia sp. of the Samanea saman
is an alternative that can be used as an environmentally friendly
pesticide.This research aimed to know the effect ofCerbera manghas leaf extract
in controlling Plusia sp. and determine the exact concentration of the level of
Plusia sp. mortality of the Samanea saman.This research uses a Completely
Randomized Design Method, which consists of 5 treatments and 4 replicates with
concentration levels of botanical pesticide. B0 = concentration Cerbera manghas
leaf extract 0 g/l of water; B1 = 5 g/l of water; B2 = 10 g/l of water; B3 = 15
g/l of wate;B4 = 20 g/l of water. The results showed that the application of
Cerbera manghas leaf extract at the concentration of 20 g/l of water is the
best concentration in controlling Plusia sp. with results initial time of death
fastest is 3.00 hours, the fastest time of turning off 50% (LT50) is 11.25
hours (11 hours 15 minutes) and total mortality amounted to 92.50%.
