Abstract
One of the best feed choices for aquaculture is sludge worms (Tubifex sp.). Sludge worms need enough protein for worm growth. Corncob is a waste that is not utilized in the environment. Corncob has protein content that can be used for sludge worm growth. Complex carbohydrates are broken down through fermentation. The purpose of this study was to optimize the development of sludge worm cultivation media based on corncobs. Sludge worms are cultured in a series of culture containers by recirculating watering. There are 3 variations of treatment, namely, treatment-I (10 %), treatment-II (20 %) and treatment-III (30 %). The parameters measured are water quality, dissolve oxygen, water flow rate, mass, number of individuals in the population, total organic matter. The results prove using corncob as a medium enrichment material prov idegood environmental results and is suitable for sludge worm. The range of temperature, pH and DO values are at the optimal conditions needed for the best fermentation process.
