Abstract

This study aims to examine the effect of probiotic (Probio-7) supplementation on the Specific Growth Rate (SGR), Feed Conversion Ratio (FCR), and Survival Rate (SR) of Nile tilapia (Oreochromis niloticus). The research was conducted from January to March 2025 at the UNU Purwokerto Laboratory. An experimental method was used with a completely randomized design (CRD), consisting of 4 treatments and 3 replications. The treatments were: P1 (feed without probiotics), P2 (feed with 8 ml/kg probiotic), P3 (feed with 10 ml/kg probiotic), and P4 (feed with 12 ml/kg probiotic). The fish used were Nile tilapia (Oreochromis niloticus) with an average length of 6.53±0.35 cm and an average weight of 2.28±0.02 g. Feed was given at 08:00 and 16:00 until satiation. Stocking density was 15 fish per container filled with 15 liters of water, and the maintenance lasted for 30 days. The feed used was commercial pellet feed supplemented with probiotics according to the treatment, containing 32% protein. The results showed that the addition of probiotics (Probio-7) had a significant effect (P<0.05) on Specific Growth Rate (SGR), Feed Conversion Ratio (FCR), and Survival Rate (SR). Treatment P4 had the highest SGR value of 2.08±0.03 g, the lowest FCR of 0.33±0.02, and the highest Survival Rate (SR) of 84±7%. Keywords: Feed Conversion Ratio; Tilapia; Probiotics; Survival Rate

Abstract

Pokdakan Sumber Mina Mandiri merupakan kelompok budidaya pembenihan ikan lele yang berlokasi di Desa Babakan, Kecamatan Karanglewas, Kabupaten Banyumas. Sistem budidaya pembenihan di Pokdakan Sumber Mina Mandiri masih bersifat tradisional sehingga mempengaruhi produktivitas benih ikan lele yang dihasilkan. Fluktuasi suhu, kualitas air dan faktor eksternal lainnya seperti hama penyakit dan predator pada budidaya benih ikan lele dapat menurunkan produktivitas budidaya tersebut. Sistem budidaya tertutup atau closed hatchery merupakan alternatif budidaya ikan yang dapat meminimalisir faktor-faktor eksternal penyebab kematian benih ikan. Sistem budidaya closed hatchery dapat didukung dengan penerapan teknologi Internet of Things untuk mengukur kualitas air yang dapat tersistem dan terdokumentasi secara realtime. Metode dalam pelaksanaan program tersebut menggunakan Participatory Rural Apprasial (PRA) dengan tahapan persiapan, pelaksanaan kegiatan, dan evaluasi. Kegiatan yang telah dilakukan oleh tim Pemberdayaan Kemitraan Masyarakat adalah pembuatan closed hatchery, pemijahan dan pendederan ikan lele, pengaplikasian IoT sebagai monitoring kualitas air (suhu, pH, dan TDS). Hasil evaluasi dari program ini adalah terjadi penurunan angka kematian benih ikan lele karena sistem closed hatchery yang terintegrasi dengan IoT mampu mengurangi pengaruh fluktuasi suhu yang dapat mempengaruhi kualitas air.
