Biokonsentrasi Faktor (BCF) dan Faktor Translokasi (TF) Purun tikus (Eleocharis dulcis) dalam Fitoremediasi Air Asam Tambang


 Acid mine drainage is mining waste that contains a lot of sulfate and heavy metals such as Fe Mn which can cause environmental damage pollute the ecosystem, therefore it needs to be managed. One way manage acid with phytoremediation techniques using Purun tikus (Eleocharis dulcis). The ability accumulate known by calculating bio-concentration factor (BCF) tranclocation (TF). This study aims determine value bio concentration (TF) in rat purun absorbing so used for coal water management. Sampling was conducted Convenience sampling method. Analysis Fe, Mn, BCF TF levels carried out an atomic absorption spectrophotometer. In study, 7.53, 30.09. While 0.77 or less than 1, this indicates accumulating metal uses phytostabilization mechanism. Then 1.44 more indicating metal, rats use phytoextraction mechanism.
