Kinerja Pertumbuhan Ikan Gurame Osphronemus goramy yang Diberi Suplementasi Tepung Daun Insulin Smallanthus sonchifolius pada Pakan

Abstract

Pertumbuhan ikan gurame (Osphronemus goramy) yang lambat merupakan masalah bagi pembudidaya. Suplementasi tepung daun insulin (Smallanthus sonchifolius) berpotensi digunakan untuk meningkatkan kinerja pertumbuhan melalui peningkatan pemanfaatan karbohidrat pakan pada ikan gurame. Penelitian bertujuan memperoleh dosis terbaik penambahan daun insulin terhadap kinerja pertumbuhan ikan gurame. Penelitian menggunakan lima perlakuan yaitu penambahan daun insulin 0,0%, 0,5%, 1,0%, 1,5%, dan 2,0% dengan empat kali ulangan. Ikan dengan bobot 0,97±0,001 g dipelihara di akuarium ukuran 80x40x35 cm3 sebanyak 15 unit dengan padat tebar 15 ekor per akuarium. Pemeliharaan dilakukan selama 60 hari dengan metode pemberian pakan at-satiation. Hasil penelitian menunjukkan pemberian daun insulin 1,5% dapat meningkatkan bobot akhir, laju pertumbuhan spesifik, rasio konversi pakan dan rasio efisiensi protein. Kesimpulan penelitian ini yaitu suplementasi tepung daun insulin 1,5% pada pakan dapat meningkatkan kinerja pertumbuhan ikan gurame.

Slow growth of gourami (Osphronemus goramy) is a problem for cultivators. Supplementation of insulin leaf flour (Smallanthus sonchifolius) has the potential to be used to improve growth performance through increased utilization of feed carbohydrates in gourami. The study aimed to obtain the best dose of insulin leaf flour on the growth performance of gourami. The study used five treatments, namely the addition of insulin leaves 0.0%, 0.5%, 1.0%, 1.5%, and 2.0% with four replications. Fish weighing 0.97 ± 0.001 g were reared in aquariums measuring 80x40x35 cm3 as many as 15 units with a stocking density of 15 fish per aquarium. Maintenance was carried out for 60 days with the at- satiation feeding method. The results showed that 1.5% insulin leaf flour supplementation could increase final weight, specific growth rate, feed conversion ratio and protein efficiency ratio. The conclusion of this study is that supplementation of 1.5% insulin leaves in feed can improve the growth performance of gourami.
