Abstract:
The waters in Cempaka Sub-district have been contaminated by heavy metals that exceed the quality of waste water standard. The process that can be used to reduce waste pollution is by phytoremediation method. Phytoremediation is a method of waste degradation using plant capability. One of the plants is the parupuk plant (phragmites karka). Parupuk plant (Phragmites karka) has a big ability to degradation the waste. Parupuk plant was included in poaceae family. The purpose of this study is to analyze the influence of mass variations and the duration of immersion of parupuk plants in absorbing heavy metals mercury. In this study begins with static phytoremediation was performed by plant mass variation of 0.5 kg, 1 kg and 1.5 kg. The Soaking period of 8 hours, 80 hours, 152 hours and 224 hours. From the result of research known, the effective condition for the parapuk plant to absorbs the heavy metals mercury is at the 8th hour of phytoremediation and 1.5 kg parupuk plant can absorb the heavy metals mercury by 90,74%.
