<![CDATA[The aim of research is to determine the optimal dose of fertilizer so that it can produce the maximum population growth. This research using Complete Random Design (RAL) method with 4 treatments and 3 repetitions. As the treatment is a dose of chicken manure (25%) and quail (75%), the dose oftreatment A 0 gr/L, treatment B 2 gr/L, treatment C 4 gr/L and D treatment 6 gr/L. Based on the results of the experiment, treatment D showed the highest results (1188,33 Ind/L), then followed by treatment C (10440,00 Ind/L), treatment B (9216,67 Ind/L) and treatment A (5440,00 Ind/L), while the responseof the population growth of Daphnia sp. to doses of chicken and quail manure in a culture media showedpolinier with the equation Y = 5939.33 + 1055.5 X (R2 = 0.96). TheCondition of water qualityduring a research is still apropiate for supporting life and population growth of Daphnia sp.The temperature during the research was 26-28,5C, DO was 2,4-3,8 mg / l, and pH was 6, 5-8, 9.Keywords: Daphnia Sp, Culture, Chicken manure, quail manure, water quality.]]>
