Utilization of Tofu Industry Waste and Banana Plant Waste for Growing Medium of Brown Oyster Mushrooms (Pleurotus cystidiosus [Jacq. Fr.] P.Kumm.)

Brown oyster mushroom is one of the consumption mushrooms
with high economic value, so it is important to be cultivated commercially.
Several types of plant and industrial wastes, such as dried banana leaves
and tofu dregs, are available abundantly in the field. The waste has the
potential to be used as medium for growing consumption mushrooms. This
is because dried banana leaves and tofu dregs contain enough nutrients
needed for the growth and development of oyster mushrooms. The study
aimed to determine the growth response and yield of brown oyster
mushrooms by giving various doses of dried banana leaves and tofu dregs
flour. The research was carried out using factorial completely randomized
design. First factor: dosage of tofu flour: 50 g per baglog, 150 g per
baglog, and 250 g per baglog. Second factor: dosage of dried banana
leaves, without dried banana leaves, 100 g dried banana leaves per baglog,
and 250 g dried banana leaves per baglog. The results showed that the
treatment of addition of tofu dregs flour with dried banana leaves
interacted very significantly in the number of mushroom caps, diameter
and thickness of the caps, the length of the mycelium, the fresh weight of
the fungus, and biological efficiency.
