Abstract

The cultivation of Daphnia magna usually uses fertilization method, both organic and inorganic fertilization. The cultivation of Daphnia magna. Usually done by using chicken manure as a culture medium to grow microorganisms as feed Daphnia magna. In addition to efforts to grow microorganisms as a source of nutrients for Daphnia magna, it is necessary additional protein intake is useful for the population of microorganisms. Protein sources obtained from Tofu dregs. Objectives to be achieved from the implementation of this research are: 1). Know the effect of dosage of manure (chicken manure) with tofu tofu as feed for population growth of Daphnia magna. 2). Knowing the population growth rate of Daphnia magna. 3). Knowing the quality of Daphnia magna as a natural food of fish seed. The research method was chicken dung manure combined with dregs of tofu (22.5 g / l tofu, 7.5 gr / l of chicken manure), (15 g / l tofu, 15 g / l of manure Chickens), 7.5 gr / l tofu, 22.5 g / l of chicken manure), (30 g / l of chicken manure), 30 gr / l tofu ) and without chicken manure and tofu dregs. The results showed that population growth, growth rate and peak population were significantly different between the treatment of chicken manure and tofu dregs. While long growth there is no significant difference between the treatment of chicken manure and tofu dregs.
