PENGARUH PENAMBAHAN DAUN KELOR SEGAR (Moringa oleifera Lamk.) DALAM PAKAN TERHADAP PERTUBUHAN DAN KELANGSUNGAN HIDUP BENIH IKAN LELE (Clarias gariepinus) STRAIN SANGKURIANG

Abstract

Ikan lele merupakan salah satu jenis ikan air tawar yang memiliki tingkat adaptasi cukup tinggi. Penelitian ini dilakukan selama 35 hari pemeliharaan dengan tujuan mengetahui pengaruh pemberian daun kelor segar pada pertumbuhan dan kelangsungan hidup ikan lele strain sangkuriang. Pemberian daun kelor segar sebagai tambahan pakan ditujukan sebagai bahan baku alternatif dikarenakan memiliki kandungan protein yang cukup tinggi sehingga mampu memenuhi pertumbuhan dan kelangsungan hidup ikan. Perlakuan yang digunakan dalam penelitian ini ada 4 perlakuan dengan 3 ulangan yaitu 100% pelet, 90% pelet+10% daun kelor segar, 85% pelet+15% daun kelor segar, dan perlakuan 80% pelet+20% daun kelor segar. Pemberian daun kelor segar memberikan pengaruh nyata terhadap bobot ikan lele sangkuriang dimana nilai tertinggi yaitu pada pemberian 80% pelet+20% daun kelor segar sebesar 6,65±2,42 gram. Pemberian daun kelor segar tidak memberikan pengaruh nyata terhadap pertambahan panjang ikan lele sangkuriang. Penambahan panjang paling tinggi yaitu pada perlakuan 85% pelet+15% daun kelor segar yaitu 2,79±0,99 cm. Pemberian daun kelor segar memberikan pengaruh nyata terhadap kelangsungan hidup ikan lele sangkuriang. Nilai SR paling tinggi yaitu pada perlakuan 80% pelet+20% daun kelor segar yaitu sebesar 91,36%. Penambahan daun kelor segar memberikan pengaruh nyata terhadap nilai FCR ikan lele sangkuriang. Nilai FCR paling rendah yaitu pada perlakuan 100% pelet yaitu 0,61%. Kadar amonia yang dihasilkan selama penelitian berkisar antara 0,17-0,19 mg/L. Kadar terendah pada perlakuan 80% pelet+20% daun kelor segar sedangkan tertinggi pada perlakuan 100% pelet.

Catfish is freshwater fish species that has a fairly high level of adaptation. This research was conducted for 35 days of maintenance with the aim of knowing the effect of fresh moringa leaves on the growth and survival of sangkuriang catfish. Giving fresh moringa leaves as a feed additive is intended as an alternative raw material because it has a high enough protein content so that it can meet the growth and survival rate. The treatment used in this study was 4 treatments and 3 repetitions namely 100% pellets, 90% pellets+10% fresh moringa leaves, 85% pellets+15% fresh moringa leaves, and 80% pellets+20% fresh moringa leaves. Giving fresh moringa leaves had a significant effect on the weight of sangkuriang catfish where the hightest value was the administration of 80% pellets+20% fresh moringa leaves of 6.65±2.42 grams. Giving fresh moringa leaves did not have a significant effect on the increase in length of the sangkuriang catfish. The highest increase in 85% pellets+15% fresh moringa leaves of 2.79±0.99 cm. Giving fresh moringa leaves had a significant effect on survival of sangkuriang catfish. The highest SR value was in treatment 80% pellets+20% fresh moringa leaves, which was 91.36%. The addition of fresh moringa leaves had a significant effect on the FCR value of sangkuriang catfish. The lowest FCR value in treatment 100% pellets which was 0.61%. The ammonia levels produced during the study ranged from 0.17-0.19 mg/L. The lowest level was in treatment with 80% pellets+20% fresh moringa leaves while the highest was in the control treatment.
