Formulasi Media Blotong Tebu, Serbuk Gergaji dan Kapur Sebagai Media Pertumbuhan dan Produksi Jamur Tiram Putih (Pleurotus ostreatus)

Abstract

Plant and oyster mushroom production, among others, is done by raw materials media, nutrition, type of isolates and environmental factors such as temperature, humidity rays and pH media. Blotong sugar cane can be used as an ingredient to plant oyster mushrooms in addition to substitute the sawdust that has been used, as well as nutrients media. The composition of these two very different materials, which causes different media decomposition, needs to add lime to fit the growing media needs of oyster mushrooms. The purpose of this research is to get the formulation of sawdust media, blotong sugarcane and lime with the right composition as a medium of growing white oyster mushroom (Pleurotus ostreatus). The experimental design used in this study was a complete randomized (RAL) factorial consisting of 2 treatment levels, Treatment A ie A0 = 100% sawdust, A1 = 100% blubber powder, A2 = 70% blub powder + 30% sawdust , A3 = 50% blotong powder + 50% sawdust, A4 = 30% blub powder + 70% sawdust, Treatment K is: K1 = 2% lime, K2 = 3% lime, K3 = 4% lime and K4 = 5 % lime The results showed the growth rate of mycelium and the working age of the fruit body at A0, while the number of fruit body and wet weight of the harvested on A4 treatment. The application of lime in the medium of sawn and sawdust was not significantly different in all treatments. Results related to treatment of 30 HSI of highest mycelium growth in A0K2 treatment. The best result of growth and production of white oyster mushroom on the A4 treatment is 30% blotong powder + 70% powder sawdust.
