Abstract

The problems of fish and plant cultivation are limited land, decreasing quality and quantity of water for human needs, food sources, and increasing population on earth. Optimization of fish farming with high stocking densities accompanied by high feeding will cause accumulation of organic matter in the culture containers which will worsen the quality of the rearing water which will ultimately have an impact on the physiological conditions, survival and growth of fish. One of the technologies for growing vegetables, fruit and fish farming that has been developed to overcome these obstacles is the Budikdamber system with red tilapia organisms and water spinach plants. The purpose of this study was to determine the quality of water with different stocking densities in the Budikdamber system with water spinach and without water spinach. The experimental design used a factorial complete randomized design with density treatment (A (2 fish/10L), B (4 fish/10L), C (6 fish/10L), D(8 fish/10L) and system (budikdamber with water spinach) (a) and without water spinach (b)). The results showed that temperature parameters ranged from 22.4 - 30.6°C, pH ranged from 6.4 - 8.9, and DO ranged from 1.07 - 16.4 mg/l. Parameters of temperature, pH, and DO are in a range that is not in accordance with optimum conditions (temperature = 25-32°C, pH = 6.5 – 8, and DO ≥3 ), but can still be tolerated by tilapia so that fish tilapia still survive. Water spinach plants can reduce ammonia so that the ammonia value in the treatment using kale decreased from week 1 to 4 and conversely, for budikdamber without water spinach, it increased from week 1 to week 4. The highest SR value was found in the Ba treatment (4 fish/10 liters) with water spinach is 91.67%.

Abstract

The high feeding and the metabolic output of the fish in intensive aquaculture can cause various problem, such as poor water quality and slowing down the fish growth performance. Recirculating Aquaculture System (RAS) is a solution to maintain water quality. Unfortunately, the conventional mechanical filter in RAS such as japmat is inefficient. One strategy that can be applied is to use a hydrocyclone. This research aims to observe the fish growth performance in RAS pond using hydrocyclone mechanical filter and its comparison with the use of japmat. Research method was performed by comparing hydrocyclone and japmat in the pond with the RAS system. The research design is completely randomized design (CRD), with three replications in each treatment. The research was carried out through five stages, namely hydrocyclone set-up, RAS ponds set-up, water quality analysis, fish growth measurement, and statistical analysis. Based on the Independent Samples Test, the use of hydrocyclone mechanical filters has a significant effect (P<0.05) on the measured water quality parameters (DO, Temperature, pH, TDS, NH3) except for NO2. Hydrocyclone significantly affect Average Daily Growth and Specific Daily Growth parameters. Whilst, the Survival Rate and Feed Conversion Ratio parameters, it did not give significant effect
