Abstract

This study is conduct to evaluate the changes of biogeophysical aspects of Leuwigajah Dumping Area (TPA) after the slidding event of municipal solid wastes in 2005. It is necessary to reuse the TPA in the future through rehabilitation and revitalitation.The study is important due to the detail engineering design (DED) of new TPA which is still in an on going process, whereas need some consideration from technical and non-technical aspects. The result of geological survey showed that there is no signifi cant changes in geological condition, whether the changes were found in groundwater and surface water quality, before and after the slidding event. At the other side, the result of existing solid waste material showed that a high heavy metals content was found in the bulk material. It isalso found that the quality of degraded material yet is closed to compost, with a C/N ratio between 12,04 to 15,74. This compost-soil is recommended for daily cover soil at the TPA. So, before operating a new TPA, landfi ll mining must be done as initial activity.To reduce or minimize environmental impact the new TPA has to apply sanitary landfi ll method.Key words : biogeophysical, post slidding , Leuwigajah dumping area

Abstract

One method to reduce emissions of CH4 from municipal solid waste landfill is to modify the final cover layer. Methane (CH4) oxidation by methanotrophs bacteria in the soil cover layer can reduce the concentration of the CH4 emission to the atmosphere. Through field experiments, tested the effect of media bed thickness, moisture and nutrient content in the form of a media bed type that is compost and paddy soil. In general, the efficiency of oxidation by using compost media is higher than the use of paddy soil cover. For both media bed, moisture content 30% more efficient in the oxidation of CH4 compared to 20%. Moisture content determines the rate of gas diffusion between media bed with its gas phase (CH4 and O2). While for a thickness of 25 cm also produced a higher oxidation rate than the 15 cm because of the methanotrophs population.keywords: landfill gas; biofiltration; methane oxydation
