<![CDATA[An increase in waste in the agricultural sector, such as tofu dregs waste, and in the industrial sector, such as sawmill waste, can cause environmental pollution problems. So an effort is needed to utilize this waste by making it a growing medium for white oyster mushrooms enriched with rice bran as additional nutrition. This research aimed to determine the production of white oyster mushrooms on teak wood powder media enriched with tofu dregs waste & rice bran. This research was carried out in Hadipolo Village, Jekulo District, Kudus Regency. This research used a factorial Complete Randomized Group Design (RAKL) with 2 factors. The first factor: the effect of rice bran (B) consists of 4 levels, namely 0% rice bran from sawdust (B1), 10% rice bran (B2), 20% rice bran (B3), 30% rice bran (B4). Second factor: the effect of tofu dregs (A) consists of 4, namely 0% tofu dregs waste from sawdust (A1), 5% tofu dregs (A2), 10% tofu dregs (A3), and 15% tofu dregs (A4). The observation data is processed using analysis of variance (Analysis of Variance) if there is a significant difference followed by Duncan's Multiple Distance Test (UJBD) at the 5% level. The research results showed that various doses of rice bran significantly affected the speed of mycelium growth, the first appearance of fruit bodies, the number of fruit bodies, the fresh weight of mushrooms during three harvest periods, and the total fresh weight of mushrooms. Meanwhile, various doses of tofu dregs waste significantly affected the speed of mycelium growth, fresh weight of second-harvest mushrooms, and total fresh weight of mushrooms. The best growth and results were obtained from the treatment of giving 20% rice bran from sawdust and giving 15% tofu dregs waste from sawdust (B3A4).]]>
