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

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.
