Abstract

Tailings, waste processing from gold ore separation (amalgamation), is generally disposed of on agricultural land, so the land became polluted and unproductive. Remediation of contaminated land can use wild plants as a potential agent of phytoremediation. Surrounding the mine area are found various kinds of wild plants that grow well and potentially as remediator plants. This study aimed to obtain the kinds of plants that grow around the gold mining activities of the people and has the potential as a crop Remediator. The study was conducted in the areas surrounding the gold mine of the people in Pesanggaran, Banyuwangi District East Java Province. Exploration carried out using wild plants transect method. Plants that had the highest IIV value has the life skills and high adaptability. Soil analysis results in tailings disposal site showed a low content of soil fertility, such as pH 7.7 to 7.9 (alkaline), C-organic (0.14%), N (0.13%), P (5.7 mg kg-1), K (0.11 me/100g), and CEC (13 me/100g). The content of heavy metals Hg and Pb were detected has exceeded the threshold value (NAV) is required, which is 251.2 mg kg-1 and 135.2 mg kg-1. The results showed that the people around the gold mine site, there are about 31 species of wild plants that have adapted, 6 species of plants which have potential as Remediator. ie Eleusine inica, Chromolaena odorata, Ageratum conyzoides, Amaranthus, spp., Sesbania grandiflora and Momordica charantia, with IIV 22.27%, respectively 22.02%, 15.20%, 14.57%, 13, 97%, and 12.49%.
