Oyster mushroom agribusiness is a sector that contributes to the agricultural sector, both products and labor. Oyster mushrooms are agricultural commodities that have an important role as a source of quality nutrition. Increasing understanding of the benefits of oyster mushrooms as a source of healthy high protein nutrition causes market demand to continue to increase. The Rancage Business Group is a community business group domiciled in Cipari Hamlet in Sarimekar Village, Jatinunggal District, Sumedang Regency, has been running a cultivation and marketing business of oyster mushrooms since 2018. The level of fresh mushroom production has reached 10 kg per day (0.3 tons per month) which has been marketed in fresh and processed forms. The problem encountered is the abundance of waste from the cultivation process in the form of harvesting baglogs. Baglog waste remaining harvest is a mushroom planting medium that has been overgrown with fungal mycelium that is not productive in growing the body of the mushroom fruit. Mushroom baglog waste will cause various problems including becoming a medium for the development of termites and hosts for pathogenic fungi. Handling of oyster mushroom baglog waste can be done through its utilization in agriculture, including: 1. Through fermentation technology, mushroom baglog waste is processed into bochation solid organic fertilizer, as well as for the nursery of microgreen vegetables and planting media in the hydroponic system, 2. Through a sticky-press technique Processed into a Grow Block for alternative fuels, 3. Through fermentation technology, waste from white oyster mushrooms is processed into liquid organic fertilizer.
