Penggunaan Bakteri Konsorsium Bacillus Cereus Sebagai Protein Pengganti Tepung Ikan Pada Pakan Ikan Nila Salin (Oreochromis Niloticus)

---

Bacillus cereus consortium bacteria is a microorganism as a source of protein that can be utilized as a feed ingredient for saline tilapia fish with relatively high protein content (50% - 65%) and easily digested by fish. This study aims to determine the effect of utilization of Bacillus cereus bacterial consortium in feed on feed efficiency, growth of saline tilapia (Oreochromis niloticus). The research method was a completely randomized design (CRD) with 5 treatments and 3 replicates. The test feed used were P0 (feed without BKBC), P1 ( feed with 5% BKBC), P2 (feed with 10% BKBC), P3 (feed with 15% BKBC), P4 (feed with 20% BKBC). The size of saline tilapia was 4-6 cm and the average weight was 2.00 ± 0.30g. Fish were kept in a bucket with a capacity of 80L and a stocking density of 10 fish/m3. Feeding test 10% of the weight of the fish, the frequency of feeding 3 times a day, namely 08.00, 12.00 and 17.00 WIB. The best result was the use of 15% B. cereus bacterial consortium which resulted in feed digestibility of 77.27%, protein digestibility of 84.69%, feed efficiency of 31.77±1.51, protein retention of 20.39±0.69, specific growth rate of 2.69±0.02, and fish survival of 96.67±5.77. The water quality of the rearing medium was 27.9-28.9℃, pH 6-7.5, DO 4-5 mg/l, and salinity 17 ppt.
