Heavy metal content in final disposal garbage site at Banda Aceh City

Abstract

The process of continuous landfill in the area of the final disposal (landfill) of waste produces pollutants such as leachate (leachate) is a liquid containing dissolved substances and suspended very fine as a result of waste decomposition by microbes. Leachate water contains decomposing organic materials and heavy metal materials. Heavy metals (Cr, Hg, Pb, Cu, Fe, Mn, Zl, Cl) present in leachate water are from waste that has been disposed to TPA Keudah Kota Banda Aceh. The author would like to do research on the adsorption of heavy metals by using Atomic Absorption Spectrophotometer in landfill leachate Banda Aceh. The purpose of this research is to get the absorption of some heavy metals in the landfill leachate by using AAS analysis method. The results of the analysis in landfill leachate solution Banda Aceh by using Atomic Adsorption Spectrohotometer its highest uptake in heavy metal parameters Iron (Fe) amounted to 10.9191 ppm, and is followed by the parameters of heavy metals (Ni) 0.9820 ppm, ( Zn) 0.4188 ppm, (Co) 0.1698, (Cu) 0.1198 ppm, (Pb) 0.0602 ppm, (Cr) 0.0502 ppm, (Hg), and (Cu) Cd) the results are not detected (ND). Considering that Indonesia in the future is still faced with environmental pollution problem as a result of the development, the restoration and rehabilitation of contaminated land needs to get mutual attention, such as by using dilution method, stabilization, and phytoremdiation technique.
