ABSTRACT
14 hectare landfill expansion in productive palm plantations pose a threat to the environment, with the first construction area of 4 hectares entirely environmental problems have not been optimal. The research objective to analyze the characteristics, the concentration of leachate in the landfill, as well as forecast the distribution of impacts based on the ebb and flow velocity Results of research on the quality of leachate is more than the limit specified under Regulation 82 of 2013. Biota water and pressure changes caused leachate concentrations relatively poor. Acus Synedra plankton distribution groups and Nitzchia palaea commonly found when tides dry,While Nitzchia palaea and Nitzchia curvula in pairs rainy. The discovery of organisms oligosaprobic and α -mesosaprobic shows the leachate polluted condition of mild to severe. Distribution deployment with the material impact of sediment and plankton drifting tide reaches 103.680 meters dry, wet tide 136.020 meters, 35.640 meters dry ebb, ebb rainy 74.520 meters at point 2 pairs of dry 1.Titik 64800 meter, plug the rainy 132.840 meters, 32.400 meters drought recede , receding rainy 38.880 meters.Need manufacture WWTP, and continuous monitoring of the quality of leachate.
Keywords: leachate, saprobic, distribution, ups and downs.
