White oyster mushroom is mushroom which is known to have a delicious taste and complete nutrition. White oyster mushroom media is usually added additional nutrients as stimulants for mushroom growth like bran, but bran is cattle feed so its availability is limited. Sludge biogas of dairy cattle and expired milk powder waste is the result of livestock waste which is still rich in carbon, nitrogen, carbohydrates, crude fiber, phosphorus, and protein which are important substances for mushroom growth. This study aims to determine the effect of differences in the composition of the biogas sludge growing media and expired milk powder waste on mushroom productivity. This study was designed with four treatments and three repetitions, the treatment is the difference in the ratio of the concentration of dairy cow biogas sludge and expired milk powder with a ratio of 0%: 0% (P0), 50%: 50% (P1), 25%: 75% (P2), 75%: 25% (P3). Data taken include fresh weight, a diameter of caps, stem length, number of caps, pinhead growth time, and harvest time, The data was processed using analysis of Variance-Completely Randomized Design Unidirectional and the average difference was tested using Duncan’s Multiple Range Test (DMRT). The best result is P2 treatment, fresh weight, a diameter of caps, stem length, and harvest time obtained the results are 124.15 gram, 10.57 cm, 5.98 cm, and 46.00 days. In this study, it was concluded that the greater the proportion of expired milk powder waste that was given increasingly increased the growth of white oyster mushrooms.
