ABSTRACT
The increasing production of oyster mushrooms (Pleurotus ostreatus) has led to a significant rise in baglog waste. This waste has the potential to pollute the environment if not properly utilized. One way to manage this waste is by processing it into compost. However, the low nitrogen content in baglog waste necessitates the addition of other materials, such as cow manure and bioactivators like EM4, to improve compost quality. This study aims to determine the effect of the composition ratio of baglog and cow manure on compost quality, as well as the optimal concentration of EM4 bacteria to enhance compost quality. The research method involved crushing the baglog waste, sieving it using a 20-mesh sieve, and mixing it with cow manure in ratios of 2:0, 2:1, 2:2, 2:3, and 2:4. EM4 was added at concentrations of 0%, 0.1%, 0.2%, 0.3%, and 0.4%, along with water. The mixture was then heaped, covered with a tarpaulin, and fermented for 28 days with weekly turning. The analyzed parameters included organic carbon (C), nitrogen (N), phosphorus (P₂O₅), potassium (K₂O), pH, moisture content, and the C/N ratio. The best treatment was found at an EM4 concentration of 0.4% and a baglog-to-cow manure ratio of 2:4, which resulted in compost containing 33.83% C, 1.94% N, 1.67% P₂O₅, 1.87% K₂O, a pH of 8.53, 8.41% moisture content, and a C/N ratio of 17.44. All these parameters have met the quality standards of the composition based on SNI 7763:2024. This study concludes that baglog waste has strong potential as a base material for compost, particularly when combined with cow manure and supplemented with EM4 as a bioactivator.
