Probiotik didefinisikan sebagai mikroorganisme yang menguntungkan. Tujuan dari penelitian ini adalah mengetahui pengaruh penambahan probiotik Bacillus spp; Lactococcus raffinolactis dan Saccharomyces cerevisiae terhadap kualitas air budidaya lele (Clarias sp.). Penelitian dilaksanakan menggunakan metode eksperimental dengan Rancangan Acak Lengkap (RAL) terdiri dari 2 perlakuan dan 4 ulangan. Perlakuan yang diberikan yaitu tanpa pemberian probiotik/kontrol (P1) dan pemberian probiotik Bacillus spp; Lactococcus raffinolactis dan Saccharomyces cerevisiae (P2). Pemeliharaan lele dilakukan selama 60 hari dengan frekuensi pemberian pakan 2 kali sehari dengan dosis 2-5% bobot biomassa. Probiotik yang digunakan adalah 100 mL/kg pakan, sedangkan S. cerevisiae dengan takaran 1 g/kg pakan. Parameter kualitas air terdiri dari suhu, pH, kadar oksigen terlarut/DO, kadar ammonia, kadar nitrit, kadar nitrat, densitas bakteri, densitas Aeromonas dan densitas Pseudomonas. Pengamatan parameter dilakukan setiap 2 minggu sekali. Hasil penelitian menunjukkan bahwa probiotik Bacillus spp; Lactococccus raffinolactis dan Saccharomyces cerevisiae tidak mempengaruhi parameter kualitas air (suhu, pH, oksigen terlarut, ammonia, nitrit, nitrat dan bakteri)

Probiotics are defined as beneficial microorganisms. The purpose of this study was to determine the effect of adding probiotics Bacillus spp; Lactococcus raffinolactis and Saccharomyces cerevisiae on the quality of catfish (Clarias sp) culture water. The study was carried out using an experimental method with a completely randomized design (CRD) consisting of 2 treatments and 4 replications. The treatment given was without giving probiotics control (P1) and giving probiotics Bacillus spp, Lactococcus raffinolactis and Saccharomyces cerevisiae (P2). Maintenance of catfish is carried out for 60 days with a frequency of feeding 2 times a day with a dose of 2-5% of biomass weight. The probiotic used was 100 mL/kg of feed while S. cerevisiae was at a rate of 1 g/kg of feed. Water quality parameters consisted of temperature, pH, dissolved oxygen, ammonia levels, nitrate levels, nitrite levels, bacterial density, Aeromonas density and Pseudomonas density. Parameter observations are carried out every 2 weeks. The results showed that the administration of probiotics Bacillus spp, Lactococcus raffinolactis and Saccharomyces cerevisie did not affect water quality parameters (temperature, pH, dissolved oxygen, ammonia, nitrite, nitrate and bacteria.
