STUDI PENGEMBANGAN TEKNIS TPA GUNUNG TUGEL KOTA PURWOKERTO KAB.BANYUMAS, JAWA TENGAH DENGAN SISTEM SANITARY LANDFILL

Abstract

Landfill is a major issue in most of Indonesian cities. Without a proper treatment landfill can be hazardous to the environment. Leachate water can be adverse if polluted the under ground and surface water. Methane gas which is a natural by product of anaerobic microbial activity in landfill , will burnt of refuse if trapped in the landfill and also will explode the refuse stack. Sanitary landfill system is the most effective method to minimize the bad effect of landfill to the environment. Gunung Tugel final disposal is an open dumping final disposal. Open dumping system is prohibited by the international law. The increasing population, and Gross Regional Domestik Product of Purwokerto city will generally increased the amount of refuse and also will actually shortened the operational time of the Gunung Tugel final disposal. To increase the amount capacity of the Gunung Tugel final disposal, it is necessary to expand the existing area and redesign it with sanitary landfill method to reduce environmental risk. The purpose of this study is to design technical development of sanitary landfill final disposal in Gunung Tugel final disposal which can accommodate all kinds of proper refuse treatment activities. The results of this study is a new sanitary landfill final disposal design with leachate collection system, gas venting device, other supporting facilities, including truck scales, and also additional heavy equipment requirements. The expense budget to built this Gunung Tugel sanitary landfill design is approximately Rp. 7.708.865.262,00.
