THE EFFECT OF PROVIDING BAGLOG WASTE FEED OF WHITE OYSTER-MUSHROOMS (Pleurotus ostreatus) AND CHICKEN’S FECES UPON THE COCOON’S GROWTH AND PRODUCTION OF THE EARTHWORMS (Lumbricus rubellus) AS THE RESOURCE OF BIOLOGY INSTRUCTION

Earthworms (Lumbricus rubellus) are commonly utilized as a feed that contains lot of proteins needed by poultry, such as aves, fish, and shrimps. The effort of improving earthworms' (Lumbricus rubellus) harvesting, in fact, is affected by the soar of the feed’s price as well. Earthworm (Lumbricus rubellus) breeders must be more innovative in finding the alternative food for the earthworms.This research employed Completely Randomized Design design through four treatments and two repetitions. In addition, the sample constituted the 640 ciliated earthworms (Lumbricus rubellus) by using randomized sampling technique. This research revealed that providing baglog waste feed of white oyster-mushrooms, the chickens’ feces, and the combination of the two gave a significantly highest effect (based on sig.
