Abstract

The high consumption of oyster mushroom (Pleurotus ostreatus) is constrained by the production capacity and the provision of mushroom seed with low quality. Also, the price of starter pure brood stock is expensive, a calculated Rp400.000-Rp1.000.000 per-bottle. This research aims to determine the effect of rice wastewater with coconut water on the growth of the mycelium pure brood oyster mushroom. The research was conducted in February 2020-March 2020 in the integrated laboratory of the Faculty of Science and Technology UIN Sunan Gunung Djati Bandung. The method used is experimental with 9 treatment of combination of rice water with coconut water concentration i.e. 100%:0%, 80%:50%, 80%:20%, 50%:80%, 50%:50%, 50%:20%, 20%:80%, 20%;50%, 0%:100%, and repeated three times. The concentration of 100% rice wastewater produced the best growth of mycelium compared to other treatments. Therefore, the rice wastewater can be used as an medium to multiply pure broodstocks of oyster mushrooms.
