One approach to minimize risks from some toxic pollutants is phytoextraction using hyperaccumulator plants. These remarkable plant species accumulate appreciable high concentration of pollutants, including cyanide than normal plants. Although cyanide is not categorized as heavy metal, its presence is considered as one of important toxic pollutants in the environment. Detoxification of cyanide contaminated soils and waters with plants seems to be a feasible option. Since plants vary in their ability to accumulate specific contaminants, it is necessary to select plant species that can both accumulate and tolerate the contaminants. This study aims to characterized plants that grow under extreme contaminated media of gold mined tailing belongs to PT ANTAM Cikotok and to analyse their potencies as hyperaccumulators. Saccharum spontaneum which was proven tolerant and dominant in the contaminated site as well as potential in producing high biomass was used in this research. The plants were grown in tailing waste media added by 0, 5 and 10 mg kg-1 CN. Organic fertilizers i.e. manure and compost were applied to increase CN uptake. The results showed that the plants were capable of growing under the highest level of CN. Application of organic fertilizer increased plant uptake. The results indicated that Saccharum spontaneum can be considered as high tolerance and potentially effective in accumulating CN in their roots and above ground portions.

Contamination of mined soil and water affects not only to agriculture system but alsofood chains and epidemiological problems. As soil metal can not be biodegraded,remediation of soil heavy metal risks has been a difficult and expensive goal. Presentlythere are several different strategies available for the clean up and restoration ofcontaminated soils. One approach to minimize risks from some toxic pollutants isphytoextraction using hyperaccumulator plants, known as phytoremediation. In thisresearch Centrosema pubescens was studied to examine its potency ashyperaccumulator against cyanide. Although cyanide is not categorized as heavymetal, its presence is considered as one of important toxic pollutants in theenvironments. Detoxification of cyanide (CN) contaminated soils and waters withplants seems to be a feasible option. Centrosema pubescens which proven tolerant anddominant in the CN contaminated environment was used in this research. The plantswere grown in tailing waste media added by 0, 10, 20 and 30 ppm CN. Different pHlevels were applied, i.e.+ 6 and +5. The results showed that the plants were capable ofgrowing under high level of CN. The results indicated that Centrosema pubescens canbe considered as high tolerance and potentially effective in accumulating CN, i.e up to3.564 ppm in roots and up to 3.564 ppm in shoot with concentration ratio (shoot/root)up to 1.13. The plants also indicated high tolerance by producing high biomass underhigh level of CN, i.e up to 36.517 g (under 20 ppm CN).
