Growth and production of white oyster mushroom (Pleurotus ostreatus) by adding coconut water to agricultural waste as a carbon source media

Abstract

White oyster mushroom is a mushroom consumption that is popular with people and has a high nutritional value. The growth medium for this fungus is a carbon-based agricultural waste that has a high lignocellulose content. The research objective is to discover the best growing media for the growth and production of oyster mushrooms. Three carbon source growing media used are oil palm empty fruit bunches, corncobs, and sawdust. Media mixed with bran and lime then soaked up to 30% water, mixed with coconut water, and carried out sterilization for 8 hours. The study was arranged using a factorial design based on a randomized block design. Data collection is done by observing the time of the pinhead’s emergence and the time taken by the fungus mycelium to fill the baglog. The results showed that the oil palm empty fruit bunches media gave the fastest growth of oyster mushrooms, which was 35 days with 14.5 fruiting fruit bodies. This shows another potential of oil palm empty fruit bunches as a cultivation medium, which so far has only been used for the polymer fiber and fertilizer industry.
