KINERJA PRODUKSI DAN KINERJA USAHA PENDEDERAN I IKAN PATIN (Pangasius hyphopthalmus) DENGAN APLIKASI PROBIOTIK PAKAN PADA SISTEM GANTI AIR DAN RESIRKULASI

Abstract

Kinerja produksi pendederan ikan patin belum optimal akibat akumulasi amonia dan efisiensi pakan rendah. RAS menyaring limbah, probiotik meningkatkan daya cerna dan kesehatan ikan. Penelitian bertujuan untuk menganalisis kinerja produksi dan kinerja usaha pada pendederan I ikan patin dengan aplikasi probiotik pakan. Penelitian selama 30 hari menggunakan rancangan acak lengkap dengan 3 perlakuan dan 7 ulangan, yaitu ganti air dengan probiotik pakan (KTR), ganti air dengan probiotik pakan (PPG), dan resirkulasi dengan probiotik pakan (PPR). Akuarium berukuran 95×40×45 cm³, padat tebar 15 ekor/L, pakan bertahap dari artemia, cacing sutra, lalu pelet. Probiotik dicampur sesuai perlakuan. Air diganti tiap 2 hari, filter RAS dibersihkan tiap minggu, dan sampling 15 hari sekali. Hasil penelitian menunjukkan bahwa aplikasi probiotik pakan pada sistem resirkulasi dapat meningkatkan kinerja produksi dan kinerja usaha pendederan ikan patin. Perlakuan PPR menghasilkan kinerja produksi dan kinerja usaha terbaik.

The production performance of striped catfish (Pangasius hypophthalmus) nursery remains suboptimal due to ammonia accumulation and low feed efficiency. RAS filter metabolic waste, while probiotics enhance digestibility and fish health. This study aimed to analyze the production performance and economic efficiency of catfish nursery phase I using probiotic-enriched feed. The 30-day experiment used a completely randomized design with 3 treatments and 7 replications: water exchange with probiotic feed (KTR), water exchange with probiotic feed (PPG), and recirculation system with probiotic feed (PPR). The aquaria measured 95×40×45 cm³, stocking density of 15 fish/L. Feed was given in stages: artemia, tubifex worms, then pellets. Probiotics were mixed into the feed according to each treatment. Water was changed every 2 days, RAS filters were cleaned weekly, and sampling was conducted every 15 days. The results showed that applying probiotic enriched feed in a recirculation system improved both production performance and economic efficiency. The PPR treatment yielded the best results in both aspects.
