Mineral Nutrient Content from Gracilaria sp. Waste as Biofertilizer on Intensive Aquaculture with Aquaponic System

Moch. Amin Alamsjah, Prayogo .


The aim of the research is to know the component macro and micro minerals solution fermentation, aquatic plants and fish through the analysis of chemical components, microbiology and physics for engineering technology of Gracilaria sp. waste as a biofertilizer on intensive fish farming with aquaponic system. Macro mineral concentrations (N, P, K, Ca, Na) and micro minerals (Fe and I) fermented solution increase based on long incubation, while the concentration of Cl tend to be difficult due to the low concentration of Cl was measured during fermentation is done. On aquatic plants and fish tests also found elevated concentrations of macro and micro minerals during the process of cultivating the aquaponic conducted, unless the concentration of Cl and I are relatively low because of the concentration of the measured is not generated (< 0.001 ppm). Media water in the aquaponic system still show a response good for aquatic plants and fish cultivated in the aquaponic system, although during treatment discoloration, smell or cloudiness media water, but for treatment in plastic packaging invisible teratology products biofertilizer on condition storage good in the indoor and outdoor, and refrigerator.
