Abstract: “The application of compost as biocover is not only mitigate the greenhouse gasses generated from inside of the landfill itself, but also to reduce the operational cost to supply cover soil and utilize compost that does not have a market. This research investigated the characteristics of compost produced by waste treatment unit (WTU) in City of Depok and its potential as biocover material to reduce methane emission. In this batch experiment, four columns used and utilized two variations of height, which are 40 cm and 80 cm and two sources of compost. Based on the assessment, the quality of compost mostly meets the requirements. Therefore, all compost can be utilized as biocover material as well as daily biocover or final cap for Cipayung landfill since they could show good performance in removing methane. Pre-treatment or curing phase is necessary to improve its quality before using it as biocover material.”
