The results of trimming the grass are routinely disposed of in a temporary waste dump (TPS) which is actually one of the potentials as raw material for the practice of waste management course which is always available for implementation and developing studies in the field of sanitation for all civitas academics. This research was a quantitative descriptive study. The stages in this research: preparation stage, observation stage, and implementation stage. The results of the physical measurement study obtained pH = 7.00-7.50, temperature = 30- 48 oC, and moisture = 44-78% (met the requirements for the decomposition process to occur in the waste to get a fast and good fertilizer). For macronutrient yields N + P2O5 + K2O = 5.34%, C-Organic = 1.61 dan C/N = 17.78% (met the requirements). For micronutrients, Fe = 5762 ppm and Zn = 17.78 (met the requirements).
