Waste Mixture Utilization as Oyster Mushroom (Pleurotus ostreatus) Growing Media

Growth media composition needs to be considered because it can affect the growth and development of white oyster mushroom (Pleurotus ostreatus). Wood factory waste in form sawdust is commonly used as mushroom’s media. However, problem arises when source growing difficult access from cultivation location. There’s a need for an alternative that cheap accessible. Some them are rice bran, soybean husk, bagasse which agricultural wastes. Therefore, this study aimed obtain best production. This was compiled using one factor completely randomized design (CRD) namely, (M1) 1 kg sengon ounce bran; (M2) husk; (M3) bagasse; (M4) sawdust, bran (M5) (M6) husk bagasse. Result showed M2 M4 with constituents able increase stem diameter, number caps, fresh weight mushroom. More than ounces more optimal supporting < dosage.
