Kajian Tingkat Kecernaan Pakan Buatan Yang Berbasis Tepung Ikan Rucah Pada Ikan Nila Merah (Oreochromis niloticus)
Abstract
Penelitian dilakukan untuk mengetahui tingkat kecernaan pakan ikan nila merah (Oreochromis niloticus) yang berbasis tepung ikan rucah . Penelitian ini menggunakan Rancangan Acak Lengkap dengan 4 perlakuan dan 3 ulangan. Perlakuan yang digunakan adalah proporsi tepung ikan rucah 405 gram, 450 gram, 495 gram dan 540 gram. Ikan nila merah sebanyak 12 ekor dengan berat 8 gram dimasukkan ke dalam 12 akuarium berukuran 60x40x40 cm. Pakan uji diberikan selama 60 hari dengan feeding rate 5% dan frekuensi dua kali sehari. Hasil penelitian menunjukkan bahwa penambahan tepung ikan rucah mampu meningkatkan kecernaan pakan ikan nila merah. Kecernaan adalah bagian pakan yang dikonsumsi dan tidak dikeluarkan menjadi feses. Tingkat kecernaan pakan terdiri dari kecernaan total dan protein. Kecernaan total pakan tertinggi terletak pada perlakuan D (70,51%±0,32). Kecernaan protein juga meningkat seiring dengan penambahan tepung ikan rucah. Kecernaan protein tertinggi terletak pada perlakuan D (80,64%±0,17) dengan proporsi tepung ikan rucah 540 gram.
