PENGARUH FITOREMEDIASI TANAMAN LOKAL TERHADAP KADAR TIMBAL (Pb) TANAH DI LAHAN PENIMBUNAN LIMBAH PERTAMBANGAN EMAS PT. ANTAM

Gold mining is closely related to land degradation caused by heavy metals such as lead (Pb), which are non-degradable, non-essential, and immobile. This study aims compare soil levels before after phytoremediation using local plants. Plant species consist of white teak (Gmelina arborea Roxb.) Pulai (Alstonia scholaris L.R.Br.), ganitri (Elaeocarpus ganitrus Roxb.), pine (Pinus merkusii Jungh), rasamala (Altingia excelsa N.) puspa (Schima wallichii K.) with the planting position on upper terrace, middle terrace lower terrace. Soil characteristics observed were texture, spH, content. The two-sample pair test (paired t-test) had a significant effect content (Sig. 1- tailed).
