Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh penambahan probiotik terhadap konversi pakan, laju pertumbuhan, kelangsungan hidup benih ikan gabus dan populasi bakteri pada benih ikan gabus. Penelitian ini menggunakan Rancangan Acak Lengkap dengan perbedaan taraf perlakuan probiotik terdiri atas enam perlakuan dan tiga ulangan. Perlakuan yang diberikan adalah PO (tanpa probiotik), P1 (2,5 ml. Kg-1 pakan), P2 (5 ml. Kg'1 pakan), P3 (7,5 ml. Kg'1 pakan), P4 (10 ml. Kg'1 pakan) dan P5 (12,5 ml. Kg'1 pakan). Berdasarkan hasil penelitian probiotik EM-4 pada pakan benih ikan gabus tidak berpengaruh nyata terhadap nilai konversi pakan, nilai konversi pakan terendah yaitu 1,11 pada perlakuan P4 (10 ml. Kg'1) dan nilai konversi pakan tertinggi 1,55 pada perlakuan PO (tanpa probiotik) . Pada laju pertumbuhan, laju pertumbuhan bobot tertinggi sebesar 3,71 % per hari dan terendah 2,14 % per hari. Sedangkan, laju pertumbuhan panjang tertinggi 1,93 % per hari dan terendah 1,74 % per hari. Nilai kelangsungan hidup tertinggi sebesar 40 % (10 ml. Kg'1) dan terendah 13,3 % (tanpa probiotik). Pada populasi bakteri adanya penambahan populasi bakteri Lactobacillus sp. dan menekan populasi bakteri Aeromonas sp. dan Pseudomonas sp.
