KEMAMPUAN EKSTRAK DAUN SEMBUNG RAMBAT (MIKANIA MICRANTHA H.B.K) SEBAGAI BIOHERBISIDA GULMA MELASTOMA AFFINE D.DON
ABSTRACT: Bittervine (Mikania
micrantha) is a kind of weed containing allelochemical compounds which can suppress
growth of plants nearby, so that Bittervine can potentially be used as
bioherbicide. This research aims to test the potentiality and effective
concentration of M. micrantha leaves extract in inhibiting seeds germination
and supressing growth of Blue tongue (Melastoma affine) weeds. This research
was conducted at Biology Laboratory, Chemistry Laboratory and Green house
facility of Math and Science Faculty of Tanjungpura University from May to
September 2014. Completely Randomized Design was used in this research with
extract concentration at 0 (g/ml), 0,17 (g/ml), 0,43 (g/ml), 0,82 (g/ml) and
1,5 (g/ml), each with three duplications. The result shows that the leaves
extract of M. micrantha can inhibit seeds germination and supress the growth of
M. affine weeds. The extract effective concentration that can lower the
germination percentage and sprout length of M. affine was at 0,43 (g/ml). The
extract effective concentration that can supress the growth of M.affine
encompassing plant height, wet weight and dry weight was at 0,17 (g/ml).
