Komposisi media berbasis limbah serbuk kayu aren untuk budidaya jamur tiram putih (Pleurotus ostreatus)

Oyster mushroom cultivation usually uses basic media of wood sawdust and additives such as ricebran, dolomite, gypsum, sugar, vitamin B complex. Generally the basic media used is sengon wood sawdust because it contains cellulose, hemicellulose, and lignin which is a requirement for oyster mushrooms. The sengon wood sawdust is limited so it is necessary to examine the potential of other basic media. One of the materials that have the potential of arenga sawdust waste because in addition to containing cellulose, hemicellulose, and lignin, arenga sawdust waste also still contain starch. This study aims to study the growth of white oyster mushroom on arenga sawdust waste based media and obtain the composition of arenga sawdust waste based media that can increase the productivity of white oyster mushroom. The results showed that the composition of 22% sengon wood sawdust, 66% arenga sawdust waste, 8% ricebran, 2% dolomite, 1% gypsum, 1% sugar + vitamin B gave good result oyster mushroom growth based on: the fresh weight of second harvest, time of mycelium spreading, the second pinhead sprout out, and second harvest age
