Abstract

The waste resulted by fish farming in form of feed waste and feces will accumulate and increase the phosphorus content in a pond. Excessive amount of phosphorus content will cause nutrient enrichment and decrease oxygen. As the result, it may impact the farmed fish. Aquaponic system can be a solution to the problem, because the plants in the aquaponic system can absorb and utilize the phosphate for the plant growth. This study aims to determine the rate of phosphate absorption through aquaponic system and determine the maximum number of kale plants that works best in absorbing phosphate. This study was conducted from July to September, 2013. It was held at the laboratory in Aquaculture Department of Agriculture Faculty, University of Lampung. This study used Complete Randomized Design with four treatments (control, 10 stems/clump, 20 stems/clump, and 30 stems/clump) and three repetitions. The result showed significant effect on the level of α = 0.05. This means that the treatment has an effect on the absorption of orthophosphate. Rate of highest phospate absorption is 0,000387 mg/L on in 24 hour. The treatment that shows the most significant influence in decreasing the concentration of orthophosphate is the one with 30 stems/clump. Key words : Aquaponic, phosphate, fish, kale
