Efek Pemberian Kotoran Ayam Dikombinasikan Dengan Ampas Tahu Terhadap Peningkatan Kualitas Pertumbuhan Daphnia. sp

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.

The Effect of Difference Dose Quail Manure Fertilizer on The Population Growth of Daphnia sp. that Cultured in Soy Stew Water

“…is obtained from suspended organic matter and bacteria from fertilizers that are put into the culture medium. The organic fertilizer that is widely used is chicken manure [6,15,16], but the results of research by Herman [17] show that quail manure produces a high growth rate. Daphnia sp.…”

Providing feed from a mixed of chicken broth and chicken manure with different dosages on nutritional content Daphnia magna

“…In general, Daphnia magna culture only uses chicken manure as feed for Daphnia magna. Cultivating Daphnia magna with chicken manure will result in a high content of ammonia in the rearing media because chicken manure contains high enough ammonia so that it can interfere with Daphnia magna in the metabolic process and absorption of nutrients [8].…”
