POTENSI ALELOPATI ELSTRAK METANOL DAUN KETAPANG (TERMINALIA CATAPPA L.) TERHADAP PERKECAMBAHAN BIJI GULMA PUTRI MALU (MIMOSA PUDICA L.)
ABSTRACT: The Ketapang leaf
(Terminalia catappa) has allelochemical compounds which can inhibit the growth
of other plants, so it has the potential to serve as a bioherbicide. This
research aims to find out the concentration of the leaf extract of Ketapang
(Terminalia catappa) that is capable of inhibiting the germination of Mimosa
pudica seed. This research was carried out in the screen house of the
Department of Biology, and the Chemistry Laboratory of the Faculty of
Mathematics and Natural Sciences, Tanjungpura University Pontianak from May to
June 2015. The research used a completely randomized design with five
replications. The treatments consisted of control (K0), concentration of the
extract of T.catappa at 10% (K1), 25% (K2), 50% (K3), and 75% (K4)
respectively. The results showed that the extract of T.catappa at concentration
of 50% (0.50 g/ml) was capable of inhibiting the germination of M.pudica weed
seed up to 100%.
