Uji Potensi Tumbuhan Akumulator Merkuri untuk Fitoremediasi Lingkungan Tercemar Akibat Kegiatan Penambangan Emas Tanpa Izin (PETI) di Kampung Leuwi Bolang, Desa Bantar Karet, Kecamatan Nanggung, Bogor

ABSTRACT The research were carried out in Hg contaminated paddy field in Kampung Leuwibolang, Desa Bantar Karet, Kecamatan Nanggung, Kabupaten Bogor. The aim of this research is to study the potency of Salvinia molesta, Oryza sativa, Monocharia vaginalis, Limnoharis flava, Paspalum conjugatum, Cyperus monocephala, Centrosema pubescens, Mikania cordata and Commelina nudiflora to accumulate Hg from contaminated soil. The treatments were fertilizer: no fertilizer (as a control), NPK, manure and compost. The result showed that the growth of each plant was significantly different. The fertilizer treatments were significantly affected plant growth. The S. molesta showed the highest biomass followed by M. vaginalis, O. sativa and C. nudiflora. Meanwhile S. molesta also showed the highest capasity to accumulate Hg/year followed by C. nudiflora, P. conjugatum dan M. vaginalis. Production of biomass and accumulation capasity of contaminant were the characteristic of accumulator plant. Based on characteristic of hyperaccumulator plant, this research suggested that S. molesta, M. vaginalis, P. conjugatum, O. sativa dan C. nudiflora were selected for fitoremediation of Hg contaminated soil.
