Fran Winarto. 13,821,0004. Effect of Addition of Corn Cob Powder Media and Wood Powder to the Growth and Production of White Oyster Mushrooms (Pleurotus ostreotus). Essay. under the guidance of Prof. Dr. Ir. Ahmad Rafiqi Tantawi, MS., As Advisor I and Dr. Ir. Sumihar Hutapea, MS., As Advisor II. This study aims to determine the best growing media formulation for white oyster mushroom (Pleurotus ostreatus), which was carried out in Sumatra Mushroom Garden, Jalan Benteng Hilir No.19 Bandar Khalifah, Percut Sei Tuan District with a height of 12 m above sea level, flat topography and soil type alluvial.This study aims to determine the best growing media formulations for white oyster mushrooms (Pleurotus ostreatus). Data collection technique in this study is using Non-Factorial Completely Randomized Design (CRD) with growing media formulation treatment factor consisting of 5 treatment levels, namely: J0 = wood powder formulation (control); J1 = corn cobs powder 25% + 75% wood powder formulations; J2 = corncob powder 50% + 50% wood powder formulation; J3 = 75% corn cobs powder + 25% wood powder formulations; and J4 = 100% corn cobs powder. This research was carried out with 4 replications. The parameters observed in this study were the percentage of mycelium life, mycelium growth covering the substrate (cm), the age of appearance of the fruit body (days), the diameter of the fruit hood (cm), and the wet weight of the harvest (gr). The results obtained from this study are growth media formulation which consists of a comparison between corncob powders and wood powder has a very significant effect on the growth of mycelium covering the substrate, the age of appearance of the fruit body, the diameter of the fruit hood and the wet weight of harvest, but not significantly affected percentage of mycelium life.. In relation to the production of white oyster mushrooms, it turns out that media obtained from 100% wood powder (J0) is still the best medium. However, these results are not much different from the production produced from J1 media, so that the media consisting of a mixture of 25% corn cobs powder and 75% wood powder can be applied as an alternative medium.
