Catfish (Clarias sp.) is a freshwater fish that is widely cultivated because it is a leading commodity. Increased production of catfish resulted in extra area of cultivated land and water use. The technology suitable to be applied is aquaponic system. In addition to saving land and water use, Aquaponic is also improving business efficiency through the utilization of nutrients from food remains and fish metabolism. Water quality is an important factor for the success of cultivation. Maintenance catfish with the addition of probiotics in aquaponic system can be a solution for maintaining water quality, because it contains bacteria that can increase nitrite to nitrate changes that can be utilized for growth of plants and do not poison the fish. The purpose of this study was to determine the effect of different probiotics in the aquaponic system towards growth rate and survival rate of catfish. The method that used in this research is experimental with completely randomized design (four  treat and five repeated) are P0 (control), P1 (probiotic A), P2 (probiotic B) and P3 (probiotic C). Analysis of data processed using Analysis of Variance. If there are significant differences then continued Duncan's Multiple Range Test. The results showed that the giving of probiotics in the aquaponic system is significantly different (p <0.05). The final conclusion is that the addition of probiotics in  aquaponic system affect the growth rate and survival rate of catfish. The highest specific growth rate (0.025%/ day) and the highest survival rate (77.8%) contained in the P2 treatment. The lowest specific growth rate (0.019% /day) and the lowest survival rate (64.4%) contained in P0 treatment (control). Keywords : Aquaponic, Catfish, Probiotic, Growth Rate, Survival Rate, Clarias sp.

The surrounding community activities in the area of milkfish ponds include residential and household waste so that it will affect the water source used for milkfish farms (Chanos chanos Forskal). Due to changes in water quality, it will be known how the condition of pond water quality will affect the abundance of phytoplankton and the growth of milkfish (Chanos chanos Forskal). This study aims to determine the relationship of plankton abundance with the growth of milkfish (Chanos chanos Forskal) in traditional ponds. The method used is the descriptive method. The study was conducted in March - May. The results of the regression analysis for plankton abundance found a relationship that affects a specific growth rate of 83% and 17% influenced by other factors. The correlation coefficient (r) obtained is 0.91 so that it can be said that the abundance of plankton influences the specific growth rate classified as strong. Based on the value of b = 0.0156x (positive relationship) means that if plankton abundance rises the rate of growth also increases by 0.015. If the plankton does not exist or 0 then the rate will decrease by 94.

Measurement Results

In intensive aquaculture farming activities will generate solid waste and liquid waste that comes from feces and leftover fish feed. The waste accumulation can lead to deterioration of water quality that affects the physiological processes, behavior, growth, and mortality of fish. Technological innovation is needed for the management of water quality and increase productivity as a result of shrinkage of cultivated land. One of the technological innovations that can be applied, namely the incorporation of fish farming with crops through Aquaponics system. This study aims to determine the effects of water spinach optimum density to absorb waste ammonia (NH3), nitrate (NO3) and nitrite (NO2) optimally to increase the survival rate and growth rate of african catfish (Clarias sp.) intensive As well as to see its effect on conversion rates and feed efficiency with aquaponics system. The method used is the experimental method. The experimental research is used to determine the effect of certain variable towards a group under controlled conditions. The results of measurements of ammonia levels during P0 showed that the treatment significantly different (p <0.05) with treatment P1; P2; and P3. P3 treatment with water spinach number 40 stems provide maximum results in lowering the concentration of ammonia compared with treatment P0 (without spinach), P1 (20 water spinach), and P2 (30 water spinach). The measurement results nitrite levels during the observation showed that all treatments there were no significant differences (p> 0.05). The measurement results also showed that the nitrate content whole of observation results showed that all treatments there were no significant differences (p> 0.05). The best feed conversion ratio was found in P3 treatment of 1.08. The best feed efficiency was found in P3 treatment 92,25%. The highest survival rate was found in P3 treatment (88.69%) in maintenance medium and lowest survival rate was in P0 treatment (26,71%) without water spinach  (control). The highest specific growth rate was found in P3 treatment (1.15%), while the lowest specific growth rate was in treatment P0 (0.79%).Results of water quality measurement supporting all treatments decreased and increased. The supporting water quality are temperature, pH, and dissolved oxygen. The decrease and increase in support water quality is caused by environmental factors such as weather. Other parameters were observed in addition to supporting the water quality is water spinach plant growth. Value growth water spinach is best found in treatment P3. In the treatment P3 water spinach growth rose 5.14 cm with an initial size of 10.92 into 16.06.

Beberapa tahun terakhir pembudidaya udang Vaname sudah meninggalkan penggunaan antibiotik untuk membantu mengatasi penyakit dalam upaya meningkatkan hasil panen, karena terbukti penggunaan bakteri menjadi semakin meningkatkan resistensi bakteri patogen terhadap antibiotik. Probiotik menjadi solusi terbaik saat ini untuk mendapatkan keberhasilan optimal pada hasil produksi budidaya udang Vaname. Tujuan dari penelitian ini supaya memperoleh pengetahuan konsentrasi terbaik penggunaan probiotik yang diberikan dengan pencampuran pakan dengan berbeda konsentrasi untuk pertumbuhan, sintasan dan FCR udang vaname (Litopenaeus vannamei). Metode yang digunakan pada penelitian ini eksperimental yang terdiri atas 4 perlakuan yaitu A (tanpa penambahan probiotik fermentasi pada pakan), B (penambahan probiotik fermentasi 0,5 liter), C (pakan dengan Probiotik fermentasi 1 liter), dan P3 (pakan dengan Probiotik fermentasi 1,5 liter) pada wadah dengan kepadatan 100 ekor/L. Hasil penelitian menunjukkan rata-rata laju pertumbuhan spesifik udang Vaname berkisar antara 0.16-0,26 %, tingkat kelangsungan hidup berkisar antara 49 – 93 %. In the last few years, vaname shrimp farmers have abandoned the use of antibiotics to help overcoming the disease as an effort to increase crop yields, because it is proven that the use of bacteria has increased the resistance of pathogenic bacteria to antibiotics. Probiotics are the best solution at this time to obtain optimal success in the production of vaname shrimp. The purpose of this study is to obtain the best concentration of probiotic use given by mixing feed with different concentrations for growth, survival and FCR of vaname shrimp (Litopenaeus vannamei). The method used in this experimental study consisted of 4 treatments namely A (without addition of fermented probiotics in feed), B (addition of 0.5-liter fermented probiotics), C (feed with 1-liter fermented probiotics), and P3 (feed with 1.5-liter fermented probiotics) in containers with a density of 100 ind./L. The results showed that the average specific growth rate of vaname shrimp ranged from 0.16 to 0.26% and the survival rate ranged from 49 to 93%.
