Abstract

The objectives of this research were to observe the production of Daitokyo Bekana (Brassica rapa L. Chinensis), Water Convolvulus (Ipomoea aquatica), and Tilapia (Oreochromis niloticus) in a small-scale aquaponic system, as well as the dynamics of nutrient in the system. Only initial organic micronutrients were added to the system. The production of Daitokyo Bekana and Water Convolvulus decreased until the end of experiment. Some nutritional disorders were found during second and third harvesting including chlorosis, interveinal chlorosis, stunted growth, wilting, and curly leaves. Electrical conductivity increased even very low (535 μS/cm at final measurement). Water sample was taken every week. Nine elements analyzed were ammonium (NH4 +), nitrate (NO3-), potassium (K+), phosphorus (H2PO4-), calcium (Ca2+), magnesium (Mg2+), sulfur (SO42-), sodium (Na+), and chloride (Cl-). Sea coral was good source for calcium. pH was unstable but tended to increase, followed by water temperature and other elements composition. Nitrogen and potassium were found as limiting factor in the systems.
