Abstract:
Uncontrolled disposal of empty fruit bunches (TKKS) on the land surrounding the palm oil
mill leads to anaerobic decomposition or large-scale decomposition processes. 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 bunches
