Pengaruh Penempatan Baglog dan Pemberian Komposisi Media Pada Produksi Jamur Tiram Putih (Pleurotus ostreatus)

Abstract

White-Oyster mushroom (Pleurotus ostreatus) is one type of fungus that grows on wood. This mushroom full of many nutrients and can be used to substitute other nutritional sources that are relatively more expensive. One of important factor in the cultivation of white-Oyster mushroom, is the availability of the substrate as a growing medium. The medium of White-Oyster mushroom must contain with the nutrients needed for growth and production. The potential utilization of agricultural waste can be used as an alternative growing medium. One of them is peanut stover. The purpose of this study was to determine the best composition in the substitution medium of peanut stover and the efficiency room with a rack placement. This study is a factorial randomized block design (RAK) with 2 treatment factors. First is rack placement namely conventional racks (R1) and hanging shelves (R2) and composition of the media consisting of 100% sawdust (K1), 25% peanut stover + sawdust 75% (K2), peanuts stover 50% + sawdust 50% (K3), peanuts stover 75% +sawdust 25% (K4) with four replicates. The result of the study showed that the best media composition was in the treatment of (K2) 75% sawdust + 25% peanut stover.  In addition, for space efficiency on the number of baglogs, the results are significantly different with the value of R1 (conventional shelf alignment) greater than R2, which is 10525 grams.
