The waste generation increases along with the increase of population and then the percentage of waste services is increasing every year so the capacity of Sukoharjo landfill becomes decreasing. While to find a suitable location for new landfill sites that are completed requirements of regulation is difficult. It is needed some actions to extend the lifetime of Sukoharjo landfill, one of them is application 3R (Reduce, Reuse, Recycle) mechanism in waste management. This study aims to analyze the lifetime of Sukoharjo landfills with the mechanism of Reuse, Reduce and Recycle (3R). The method used in this research is quantitative and qualitative methods. Based on the calculation, the landfill only available until 2022. The existence of composting and recycling of anorganic waste, landfill lifetime will extend until 2025. Our results show that there is a significant comparison of the volume waste in landfills between untreated incoming trash with treated by Reduce, Reuse, Recycle (3R) mechanism. By 2028, the waste generation in a landfill will be 24,821,724 kg. During composting (30%) and recycling of anorganic waste (15%), the volume of waste in landfill is reduced to 14,401,796 kg.
