Abstrak: This research aims to analyze the effect of circulation system and recirculation system on population growth and biomass of worms, media maintenance quality, and business prospects. The treatment in this study consisted of the circulation and recirculation system. the experiment was conducted from September to December 2013 held at Miranti Fish Farm.The media used is a micture of sludge dan chicken manure 1 : 1 with the cultivation of container in the form of a wooden box with size (200x100x20) cm3 covered with blue tarp for 6 units. The fertilizer that been used is fermented chicken manure mix with tapioca flour. Manure and mud inundation conducted over 10 days and then spread the worms into the media and fertilized once every 5 days. The worms maintained for 60 days and performed sampling every 10 days. The results showed that the recirculation system treatment reached highest population and higher biomass. The highest population is at (3,4 x 106 ind./m2) in the 40 days culture periode and the highest biomass (9.27 kg/m2) reached in 60 days. In the Circulation system the highest population is 2,07 x 106 ind./m2 and the highest biomass is 9,09 kg/m2 which achieved in 60 days. Recirculation system is more viable than the circulation system, with benefits of save more water and generate higher profits.

Judul: Produktivitas Budidaya Cacing Sutra (Oligochaeta) dalam Sistem Resirkulasi Menggunakan Jenis Substrat dan Sumber Air yang Berbeda
Abstrak: Tubificid worm have been used as live food which is important for ornamental fish production as well as other fish hatchery. This is because it has high protein content up to 52,49%. Many research have been done regarding tubificid culture, the result however still lower than that of natural production. The aim of this research was to increase productivity of tubificid worm in a recirculation system by using different types of substrate and source of water. This researching consisted of 4 treatments, i.e. ground water with sand substrate (SP), ground water with mud substrate (SL), catfish culture effluent with sand (LP), and catfish culture effluent with mud (LL). The research was done from May to August 2011 at Cibanteng, Laboratory of Fish Environment, and Laboratory of Fish Nutrition. Cultivation media was made by mixing the substrate and fermented chicken manure at ratio 1:1 , which drown in 2 cm height of water level. After 10 days drown the worm was stocked at 69 gram/m2. Culture period occurred was 60 days with addition of manure every 15 days. Biomass sampling was done every 15 days. The result of this research showed that biomass of worm cultured in LP medium is higher than in SP, SL, and LL, whereas in LL is the lowest biomass. Biomass growth of the worm in all treatment was significant at day 45th and 60th , where as the highest biomass (89,56 gram/m2) reached at day 45th on LP treatment.
