Abstract

Penggunaan probiotik dalam budidaya ikan nila merah merupakan strategi yang efektif  karena  dapat  meningkatkan  kualitas  air,  memperbaiki  keseimbangan mikrobiota usus, serta mengurangi patogen di lingkungan, sehingga mendukung pertumbuhan dan kelangsungan hidup ikan nila. Adapun tujuan penelitian ini yaitu untuk menganalisis pengaruh pemberian probiotik buatan dengan dosis yang berbeda terhadap pertumbuhan dan kelangsungan hidup benih ikan nila merah (Oreochromis niloticus). Rancangan percobaan yang di gunakan yaitu metode rancangan acak lengkap (RAL) dengan 4 perlakuan 3 kali ulangan. Hasil penelitian menunjukan pemberian probiotik tersebut dengan berbagai dosis memberikan pengaruh nyata terhadap pertumbuhan benih ikan nila baik pertumbuhan berat mutlak maupun pertambahan panjang mutlak. Pertumbuhan berat mutlak tertinggi pada pemberian probiotik dengan dosis 100 mL (C) 1,65 g, disusul probiotik D (150 mL) 1,56 g, probotik B (50 mL) 1,33 g dan A tanpa probiotik (0 mL) 1,27 g. Sedangkan pertambahan panjang mutlak tertinggi pada probiotik C (100 mL) 2,10 cm,  probiotik B (50 mL) 1,61 cm, probiotik D (150 mL) 2,09 cm dan probiotik A (0 mL) 1,36 cm. Tingkat kelangsungan hidup berpengaruh nyata tiap probiotik dengan Tingkat kelangsungan hidup. probiotik A (0 mL) tingkat kelangsungan hidup 100%, Probiotik B (50 mL) 100% dan probiotik C (100 mL) dan D (150 mL) memperoleh hasil sebesar 100%.Kata Kunci: Kelangsungan hidup , nila merah , pertumbuhan, probiotik.

Abstract

Papain is a proteolytic enzyme extracted from unripe papaya (Carica papaya) fruit and functions as a catalyst in the hydrolysis of proteins into simpler compounds. In aquaculture production, feed costs account for approximately 60–70% of total production expenses, highlighting the need for high-quality feed with enhanced utilization efficiency. This study aimed to analyze the proximate composition of feed supplemented with papain enzyme and to evaluate its effects on feed utilization efficiency (FUE) and protein efficiency ratio (PER) in freshwater crayfish (Cherax quadricarinatus). The feeding trial was conducted at UKM Kasih Karunia, Bube Village, Suwawa District, Bone Bolango Regency, Gorontalo, Indonesia. The study employed an experimental research design consisting of two treatments and three replications. The results showed that feed supplemented with 3.5% papain enzyme contained 41.10% crude protein, 20.35% moisture content, 2.71% crude fat, 6.35% crude fiber, 36.00% nitrogen-free extract (NFE), and 13.84% ash content. Furthermore, the feed utilization efficiency of the papain-supplemented diet reached 49.47%, which was considerably higher than that of the control diet without papain supplementation, which recorded an FUE value of 16.32%. These findings suggest that the inclusion of 3.5% papain enzyme in feed improves its nutritional quality and significantly enhances feed utilization efficiency in freshwater crayfish (C. quadricarinatus), thereby demonstrating its potential as a feed additive for aquaculture applications.
