INNOVATION OF PRODUCING THE NATURAL FEED OF TUBIFEX  IN ORGANIC WASTE MEDIA  

Tubifex worms are one of the natural food alternatives, especially in the larval stages of fish and fish seed. Tubifex have good nutrient content and tend to be well-balanced and very good for the growth of fish. In the body of Tubifex worms contained approximately 57% protein and 13% fat (S. Alex, 2011). Tubifex worms worm also called sludge worms, sewage worms, and lime snake, because it can live well on a lot containing waste waters and sludge / sediment organic sludge can even live in heavily polluted waters organic matter that almost no other species can survive. Protective cyst formation and decreased activity of metabolism is a strategy to tubifex worms live that can survive in drought conditions and lack of food. Tubifex worms are widely used as food for fish larvae and seeds, either in the form of live, freeze dried, or in the form of pellets. But most of the source is not cultivated but derived from the nature of the arrest. Care should be taken when it is used as a feed tubifex worms in the aquarium fish. Studies of cultivation techniques to approach the production scale of enterprises is still limited. From the results of this engineering in the amount of data tubifex get as much as 257 kg of months of May to November 2014, which is derived from a pool of three blocks of size 2x2 m² using media materials of pulp, molasses, bran fine with the initial stocking density of 30 kg seed.
