Abstract
The amount of waste continues to increase from year to year, one of which is due to the population increase. With the target of 100% service level by 2020, Indonesia must prepare the land that will be used as a landfill location in order to accommodate the waste that continues to be produced. Apparently, the problem is not only limited to the provision of land, but operational challenges become more severe. One of its is experienced by Piyungan Landfill, Bantul, Yogyakarta which has been designed to expire by 2015. The government of Yogyakarta is optimizing for landfill can still operate until 2018. One solution that can be given in operation for the loop cycle or closed cycle concepts is landfill mining method, which is utilizing degraded waste into other designations so that the land can still be used to accommodate other waste. Sampling and analysis results show that the waste contained in 1st zone Piyungan landfill aged 15-20 years, with the highest composition is soil (59%) dominate other types of waste. The soil obtained has the potential to be utilized as cover soil and compost, but for compost is necessary to further study the modification of the design of the zoning zone, so that the waste not too long is in the soil so that the nutrient content is still high.
