Gases that pollute atmospheres such as CH4, H2S, NH3, and Nox gas can be produced from decomposition processes of TKKS and leachate production resulting in contamination of groundwater and surface water. Globally these gases cause greenhouse effect, whereas locally can cause odor and impact of health. Seeing the potential of the amount that every hour of production as solid waste and the impact of environmental pollution then waste TKKS must be managed wisely. In this study, the evaluation of C/N and lignin values as an indicator of degradation of TKKS waste by white fungus mushroom is mushroom (Volvariella volvacea). This study it can be concluded that there is a linear relationship in the degradation process by the fungus (Volvariella volvacea) in the empty fruit bunches between the percentage value of lignin degradation and the C / N ratio for 25 days of fungal growth. Mushroom (Volvariella volvacea) as a white root fungi mushroom can be used to speed up the process of degradation of empty fruit bunchesenwhite root fungiempty fruit bunchligninC/NdegradationArticle
