Abstract

Penelitian ini bertujuan untuk menganalisis pengurangan kadar protein pakan pada teknologi bioflok terhadap performa produksi. Penelitian dilaksanakan pada bulan Februari–April 2024 di hatchery Instalasi Praktek Lapang Komunikasi dan Penyuluhan Politeknik Ahli Usaha Perikanan. Penelitian ini menggunakan metode eksperimental, dengan Rancangan Acak Lengkap (RAL) 4 perlakuan dan 3 kali ulangan, X0(NB) protein 32% kontrol, X1(B) protein 32%, X2(B) protein 28% dan X3(B) protein 25%. Variabel yang diamati yaitu performa produksi lele dumbo serta pengaruh penurunan kandungan kadar protein pakan dalam teknologi bioflok. Hasil penelitian menunjukkan bahwa kualitas air oksigen terlarut, pH, suhu, nitirt, dan TSS tidak berbeda nyata antar perlakuan (P<0,05), sedangkan TAN berbeda nyata antar perlakuan (P<0,05), tetapi masih dalam rentan yang layak. Performa produksi pertumbuhan spesifik, pertumbuhan mutlak, berat akhir, biomas berbeda nyata antara X3(B) dengan X0(NB), X1(B) dan X2(B), dengan nilai terendah pada kolam X3(B) protein 25% dan nilai tertinggi pada kolam X1(B) protein 32%. Kelulushidupan X3(B) protein 25% berbeda nyata dengan X1(B) protein 32% dan rasio konversi pakan X3(B) protein 25% berbeda nyata dengan X1(B) protein 32% dan X2(B) protein 28%. Performa produksi kolam X2(B) protein 28 % dalam teknologi bioflok dapat diaplikasikan dalam budidaya lele dengan efesiensi biaya produksi 18,03 % dari kolam XO(NB) protein 32 % kontrol.
