| dc.description.abstract | Phytoremidiation is a simple technique in waste water treatment processing, by utilizing the plant activity to
remove, replace and stabilize or destroy the pollutant for both organic and inorganic component.
Pytoremidiation technique had been used in USA and Europe however this technique is considered new in
Indonesia. This research studied influence of tofu waste concentration and the type of water plant for
changing of mass, the length of root, and the length of rod in accordance with time and to discover the
efficiency of decreasing of Chemical Oxygen Demand (COD), Total Suspended Solid (TSS), and pH in
accordance with the variation of tofu waste concentration and the type kind of water plant.The materials
used in the research are Equisetum hyemale, Ipomoea aquatica Forsk, and Eichornia crassipes (Mart.) Solm
while the tool used is bottle of mineral water. The research is divided into two steps namely acclimation and
phytoremidiation. In the acclimation step, 75 gram of water hyacinth is poured into 500 mL of water. The
plant was soaked in the water for 5 days. In phytoremidiation process, 250 mL of tofu waste with different
concentration, i.e. 12.5, 25, 37.5, 50, 75, 87.5, and 100 per cent of volume. The length of root, the length of
leaf and change of mass to time are measured every 12, 24, 36, 48, 60, 72, 84, 96, 108 and 120 hours. The
process was repeated for every water plant. The experiment result shows that the concentration of tofu waste
and the type of water plant influences the change of mass, the length of root, and the length of rod. In the
variation of concentration, 25-62.5 per cent of volume, 75 per cent of volume and 100 per cent of volume the
plant was die after 108 hours, 96 hours, and 84 hours are respectively. For the variation of type of water
plant, the percentage tofu waste can be absorbed by Ipomoea aquatica is 83.02 % better than Equisetum
hyemale and Eichornia crassipes (Mart.) Solm) are 74.54 % and 64.08% respectively. | en_US |
