Abstract

Leachate concentration for Pb and Mn parameters from TPA Ngronggo, Salatiga  are exceed equal to Perda Jateng No. 5/ 2012, consentration of this parameters are  0,75 mg/l and 14,1 mg/l. Contamination of heavy metals are spreads from water soil current to landfill region. This landfill used controlled landfill method. Formation of lining system are gravel, geotextile, geomembrane, compacted clay, and soil. The result from monitoring well are suspicion because of transport contaminant from landfill are attain to 7,1m of depth. Simulation of this phenomena can use Pollutev.7 software, we can see 1,5 dimensional of the result. Prediction consentration for 15 years are Pb 0,6728 and Mn 12,5 mg/l.

Abstract

Sanggrahan Landfill (Temanggung), completed with  gravel, geotextile, geomembrane, and compacted clay. It’s still has  potential of contaminant mobilization through those liners that comes from solid waste in landfill. The purposes of this research  for knowing the movement cadmium (Cd) and nickel(Ni) in leachate vertically in every depth.  The contaminant movement  from active zone head  for control 1-well and  from active zone head for control 2-well could be predicted by using model pollute v7 software. Pollute v7 is one dimension model, where needed the characteristic of the liners (depth, permeability, porosity, dry density, coef dispersion of hydrodinamics). This model describe the contaminant mobilization affected by dispersion, advection, diffusion, and retardation phenomenon. Based on 12 years forward model simulation in this study, the concentration of Cd and Ni will get increase. The results showed, value of cadmium concentration in control 1-well is 0,496 mg/l and in control 2-well  is 0,4064 mg/l. Whereas, the value of nickel concentration in control 1-well is 0,382 mg/l and in control 2-well is 0,3665 mg/l. This prediction showed that  Sanggrahan Landfill has potential in leachate mobilization. The study suggests that the application of geomembrane should has lower permeability than 0,5x10-12m/s for retarding contaminant transport.
