Abstract


Indonesia produces a large amount of oil palm empty fruit bunch (EFB). EFB has potency as media for oyster mushroom cultivation. The aim of this research was to study the growth of oyster mushroom (Pleurotus ostreatus) at various EFB compositions as the growth media. The media consisted of mixture of EFB and sawdust at various compositions, rice bran, CaCO3, and TSP fertilizer. The composition of EFB to sawdust were 0%, 25%, 50%, 75%, and 100%. The data were collected on mycelium growth and weight of the mushroom. During cultivation in baglog, there were no different in mycelium growth rate. After 30 days cultivation, all baglog were occupied with the mycelium at all media compositions. The EFB composition of 25% showed faster growth among the other compostions followed by the EFB composition of 50%, 75%, and 0%. The highest biological efficiency ratio (BER) of 56,25% was obtained at media composition 50%. The EFB contained in baglog also showed biodelignification process. Biodelignification has benefit which can reduce the use of chemicals in the delignification process to convert EFB into cellulose. The highest lignin reduction, 40.12%, occured in 75% of EFB media composition while for hemicellulose, 49.56%, occured in 100% EFB media composition.
