Tanaman wori merupakan salah satu tanaman kelompok fabaceace yang tumbuh melimpah di Sangihe dan sangat potensial digunakan sebagai salah satu sumber pakan ikan. Kadar protein daun wori adalah 25,53% sehingga berpotensi menjadi protein nabati bagi ikan. Kendala utama yang ditemui ketika memanfaatkan daun tanaman wori adalah kandungan karbohidrat yang tinggi yaitu 48,51% sehingga dapat mempengaruhi proses pencernaan ikan, penyerapan nutrisi yang berujung pada rendahnya pertumbuhan ikan. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh tepung daun wori femerntasi terhadap laju pertumbuhan spesifik dan sintasan hidup ikan nila. Rancangan percobaan yang digunakan adalah Rancangan Acak Lengkap (RAL). Perlakuan yang dilakukan terdiri dari tiga perlakuan dan tiga kali ulangan yaitu kadar tepung daun wori tanpa fermentasi A (kontrol) 10%, kemudian B tepung daun wori fermentasi (10%), dan C tepung daun wori fermentasi (20%). Laju pertumbuhan spesifik dan efisiensi pakan diuji menggunakan ANOVA sedangkan sintasan hidup akan dianalisis secara deskriptif. Hasil penelitian ini menunjukan bahwa penambahan tepung wori fermenasi dalam pakan dapat meningkatkan nilai laju pertumbuhan spesfik ikan nila dan efisiensi pemanfaatan pakan dengan nilai tertinggi pada perlakuan C yaitu SGR 1,94%/hari. Sementara itu, untuk semua perlakuan nilai sintasan hidup sebesar 100%.   The wori plant is one of the plants of the fabaceace group that grows abundantly in Sangihe and has potential to be used as a source of fish feed. The protein content of wori leaves is 25.53%, so it has the potential to become vegetable protein for fish. The main obstacle encountered when utilizing wori plant leaves is the high carbohydrate content of 48.51% so that it can affect the digestion process of fish, nutrient absorption which lead to low fish growth. The purpose of this study was to determine the effect of wori femerntation leaf meal on the specific growth rate and survival of tilapia. The experimental design used was a completely randomized design (CRD). The treatments consisted of three treatments and three replications, namely the content of fermented wori leaf powder, A (control) 10%, then B fermented wori leaf powder (10%), and C fermented wori leaf powder (20%). Specific growth rate and feed efficiency were tested using ANOVA, while survival rate was analyzed descriptively. The results of this study indicate that the addition of fermented wori powder in the feed can increase the value of the specific growth rate of tilapia and feed utilization efficiency with the highest value in treatment C, namely SGR 1.94% / day. Meanwhile, for all treatments the survival rate was 100%.

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.
