| Abstrak (Bhs. Indonesia) | Tujuan penelitian untuk mengetahui pertumbuhan, efisiensi pakan, FCR (Feed Conversion Ratio) dan kelangsungan hidup benih ikan lele diberi pakan komersial dengan kandungan protein rendah dan penambahan silase ikan rucah. Metode penelitian adalah eksperimental berdasarkan rancangan acak lengkap (RAL) dengan 4 perlakuan dan 4 kali ulangan. P1: 100% pakan komersial dan tanpa silase ikan rucah; P2: 80% pakan komersial dan 20% silase ikan rucah; P3: 60% pakan komersial dan 40% silase ikan rucah; P4: 40% pakan komersial dan 60% silase ikan rucah. Pemeliharaan benih ikan lele dilakukan selama 42 hari. Variabel penelitian meliputi pertumbuhan, efisiensi pakan, FCR dan kelangsungan hidup. Hasil menunjukan bahwa penambahan silase ikan rucah pada pakan komersial berprotein rendah mempengaruhi pertumbuhan (SGR dan LPH), efisiensi pakan, FCR dan kelangsungan hidup. Nilai SGR berkisar 1,582 ± 0,143 - 2,445 ± 0,221 %/hari. Nilai LPH berkisar 0,092 ± 0,017 - 0,177 ± 0,018 g/hari. Nilai efisiensi pakan berkisar 26,22 ± 2,622 - 41,14 ± 1,719 %. Nilai FCR berkisar 2,42 ± 0,963 - 3,83 ± 0,386. Nilai kelangsungan hidup berkisar 63,75 ± 12,50 - 95,00 ± 4,08 %. Variabel pendukung adalah kualitas air (suhu, pH, dan oksigen terlarut). Hasil menunjukan bahwa kualitas air selama penelitian yaitu suhu 23 - 280C, pH yaitu 7, dan oksigen terlarut 3,5 - 4,6 ppm. |

| Abtrak (Bhs. Inggris) | The research to determine the growth, feed efficiency, FCR (Feed Conversion Ratio) and seed viability of commercial catfish fed with a low protein content and the addition of trash fish silage. Experimental research method is based on a completely randomized design (CRD) with 4 treatments and 4 replications. P1: 100% commercial feed and no trash fish silage; P2: 80% and 20% of commercial feed silage trash fish; P3: 60% and 40% of commercial feed silage trash fish; P4: 40% and 60% of commercial feed silage trash fish. Maintenance of seed catfish conducted for 42 days. The research variables include growth, feed efficiency, FCR and survival. Results showed that the addition of trash fish silage on commercial feed low protein affect growth (SGR and LPH), feed efficiency, FCR and survival. SGR value ranges from 1.582 ± 0.143 to 2.445 ± 0.221% / day. LPH Value range 0.092 ± 0.017 to 0.177 ± 0.018 g / day. Feed efficiency value ranges from 26.22 ± 2.622 to 41.14 ± 1.719%. FCR value ranges from 2.42 ± 0.963 to 3.83 ± 0.386. Value survival ranges from 63.75 ± 12.50 to 95.00 ± 4.08%. Advocates variable is the quality of the water (temperature, pH, and dissolved oxygen). The results showed that the water quality during the study ie a temperature of 23 - 280C, pH is 7, and the dissolved oxygen from 3.5 to 4.6 ppm. |
