POTENSI EKSTRAK GULMA DAUN SEMBUNG RAMBAT (MIKANIA MICRANTHA H.B.K) SEBAGAI BIOHERBISIDA PENGENDALI GULMA PUTRI MALU (MIMOSA PUDICA L.)
ABSTRACT: Sensitive plant
(Mimosa pudica) is one of weeds that may cause harm to cultivated plants, both
in terms of quantity and quality of production. Climbing hempweed (Mikania
micrantha) has alelokimia compounds in form of phenol, terpenoids and
flavonoids that can be used as bioherbisida. This study was aimed to determine
the concentration of Climbing hempweed leaf (M. micrantha) extract to inhibit
the germination and growth of Sensitive Plant (M. pudica). This research was
conducted in February to April 2016 in Biology Department Screenhouse, Faculty
of Science and Mathematics and Wood Technology Laboratory, Faculty of Forestry,
Tanjungpura University, Pontianak. The study used completely randomized design
which was consisted of 5 treatments and 5 replicates, the total were 25 units
of trial. The climbing weed extract used as control were 0.1; 0.3; 0.5 and 0.7
g/ ml. The results showed that the extract with
a concentration of 0.5 g / ml could inhibit the germination percentage
and length of sensitive plant (M. pudica). M. micrantha leaf extract at a
concentration of 0.3 g / ml could inhibit the growth such as the height, root
length, wet weight, and dry weight of sensitive plant.
