Abstract

Sanitary Landfill is a landfill with trash landfill in layers on land that has been prepared, leveled and compacted, then covered with soil cover each end of the operation. When rainwater infiltrating the landfill surface and water flows out of the landfill will bring a variety of mineral and organic matter in the form of suspension cannot be separated. Final cover on the land application heap plays an important role; the infiltration rate of the cover can be minimized in various ways such as by modifying the composition of the cover layer material (Clay Cover) on Sanitary Landfill. This study examined the performance of the sanitary landfill cover. Varying the amount of soil cement mixed PCC as overburden is o%, 5%, 10%, 15%, and 20%. The parameter used is the value of the water content in each variation of the cover layer.Keywords: sanitary landfill, stabilization, clay, final cover

Abstract

ABSTRACT The aim of the study is to analyze the physical characteristic of PCC cement variation used as final clay cover at sanitary landfill through column model testing of final clay cover infiltration. The result showed clay plasticity (CL) stabilization is low with cement variation of 0%, 5%, 10%, 15%, and 20% at column infiltration model. The highest infiltration (460 cm³/minute) is detected at clay without any cement stabilization while the lowest is for the 10% concentration with result of 23 cm³/minute. Its permeability decreases with the increase of cement concentration to as high as 10%. Permeability coefficient value (k) for 0% cement is 7,71 x 10-5 cm/second and 7,46 x 10-6 cm/second and 1,51 x 10-7 cm/second for cement concentration of 5% and 10%, respectively. However for concentration above 10%, the permeability coefficient value increases as high as 1,67 x 10-6 cm/second and 2,04 x 10-5 cm/second for cement concentration of 15% and 20%, respectively. Thus, from this study it can be concluded final clay cover for sanitary landfill can be used with various cement concentration up to 10%. Keywords: bleeding, density factor and slump value
