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%.
