Abstract

Pemeliharaan ikan lele yang dilakukan pembudidaya ikan sebagian besar tidak melakukan upaya pengelolaan kualitas air seperti sirkulasi maupun penggantian air (water exchange). Salah satu teknologi untuk menjaga kualitas air media budidaya adalah menggunakan sistem resirkulasi. Tujuan dari kegiatan ini untuk mengaplikasikan sistem resirkulasi dengan mengunakan filter dalam pengelolaan kualitas air sehingga diperoleh kualitas air yang mendukung bagi budidaya ikan lele. Metode penelitian terdiri dari dua perlakuan yaitu P0: perlakuan non filter dan P1: perlakuan sistem resirkulasi dengan filter. Hasil yang diperoleh menunjukkan bahwa pengunaan sistem resirkulasi menggunakan filter dapat memperbaiki kualitas air yaitu penurunan kandungan amonia  yaitu dari 2,6 menjadi 0,1 mg/l, pertumbuhan panjang ikan lele sebesar 9,48 cm, pertumbuhan bobot ikan lele sebesar 37,15 g dan kelangsungan hidup sebesar 94%.

Abstract

The Mahseer (Tor soro), an omnivore with herbivorous tendencies, requires a balanced combination of plant and animal-based nutrients. Lemna perpusilla shows high potential as a cost-effective, plant-based feed ingredient. This study aimed to determine the optimum combination of L. perpusilla meal and commercial feed to maximize the growth performance of T. soro. A completely randomized design (CRD) was employed with five treatments and three replications: P0 (100% L. perpusilla), P1 (75% L. perpusilla + 25% commercial feed), P2 (50% L. perpusilla + 50% commercial feed), P3 (25% L. perpusilla + 75% commercial feed), and P4 (100% commercial feed). The results revealed that P3 was the optimal formulation, showing the highest growth rates, protein efficiency ratio, and feed conversion ratio as follows: absolute weight growth of 0.66 ± 0.14 g, absolute length growth of 0.73 ± 0.06 cm, a protein efficiency ratio (PER) of 2.71 ± 0.65, a feed conversion ratio (FCR) of 1.24 ± 0.28, and a 100% survival rate. Water quality parameters remained within the tolerable range for T. soro culture. In conclusion, incorporating 25% L. perpusilla meal into commercial feed significantly supports growth performance, providing a clear and effective strategy for sustainable T. soro culture.
