Abstract:

Indonesia is currently faced with a variety of problems, including relating to increasing food demand and prices, increasingly scarce clean water, and poverty. Therefore, the development of aquaponics technology has been carried out, which integrates aquaculture and hydroponics. This study was conducted to compare water quality (pH, temperature, ammonia, nitrite, and nitrate) produced from 2 different systems, namely aquaponic with modified conventional aquaculture systems. In an aquaponic system, water recirculation follows the steps: Water from a fish pond tank (FPT), flows to mechanical tanks-1(MT-1), biofilter tanks (BT), mechanical tanks-2 (MT-2), to hydroponic plants (HP), and finally back to FPT, and so on. While conventional aquaculture systems, water recirculation is only through FPT, MT, and BT. The results were obtained for aquaponic (ammonia 0.350-5.946 mg/L, nitrite 0.193-0.880 mg/L and nitrate 1.031-5.542 mg/L), and for modified conventional aquaculture systems (ammonia 0.350-9.353 mg/L, nitrite 0.114-0.880 mg/L and nitrate 0.949-1.031 mg/L). While the pH and temperature values for the two systems are the same, pH 7.18-8.9, and water temperature 26.7- 30.0°C. After the ttest, both showed a significant difference where the aquaponics system was better than the modified conventional aquaculture system because the aquaponic system was supported by the presence of MT-1, BT, MT-2, HP, and FPT, while the modified conventional aquaculture systems were only supported by MT, BT, and FPT.

Indonesia is one of the developing countries, some of the problems encountered are increasing food demand, rising food prices, scarcity of clean water, and poverty. Another obstacle is the reduction in agricultural land, along with the increase in the number of population increases, so that the increasing number of people such as the measuring series is not comparable to food needs. One of the technologies that are feasible to develop is aquaponics technology supported by biofilter so that optimal water quality is obtained.1-2 Based on the results of the research that has been done, show that the application of biofiltration ponds can increase production, land use and can save water usage during fish maintenance, while aquaponics systems are an integration between hydroponic plants and aquatic aquaculture, and become one of the effective solutions for food supply during the land crisis began to occur.3 In aquaponic systems, waste products from a biofilter system will be used as a nutrient. Waste from aquaculture animals will be used as a nutrient for hydroponic plants. The use of wastewater from aquaponic animals will be filtered, so as to produce water that can be a nutrient for hydroponic plants. The process is carried out repeatedly which is known as the recirculation system. The aquaponics system has many advantages, namely saving land
