Population growth resulted in an increase to the amount of waste entering the landfill Jatibarang. The existence of the current landfill impact on the surrounding communities. The government made plans to redesign the landfill Jatibarang optimize the function of the landfill so that the impact of losses can also be reduced. Therefore, this study aims to determine the public perception of the impact of the benefits and disadvantages, knowing the economic valuation of the impact of economic and engineering analyzes of landfill Jatibarang redesign. The method used in this research is descriptive analysis to determine public perception, methods of productivity and enjoyment value method (Hedonic Pricing) for the analysis of economic valuation and economic analysis techniques for using the Net Present Value (NPV), Benefit Cost Ratio (BCR), Profitability Index (PI), Internal Rate of Return (IRR), Payack Period (PP) and sensitivity Analysis.
