Penelitian ini bertujuan untuk mengetahui pengaruh kadar protein pada pakan terhadap pertumbuhan gurami (Osphronemus goramy). Penelitian dilakukan pada bulan Mei-Agustus 2020 bertempat di Kolam Percobaan Departemen Perikanan, Fakultas Pertanian Universitas Gadjah Mada. Perlakuan menggunakan pakan dengan kadar protein berbeda yaitu 26%, 27% dan 28%, dengan tiga kali ulangan. Frekuensi pemberian pakan dilakukan sebanyak satu kali sehari pada jam 13.00 dengan ad satiation. Pengaruh kadar protein diamati dari pertumbuhan dan konversi rasio pakan selama 10 minggu pemeliharaan. Gurami dengan ukuran 250-350 g dipelihara dalam bak beton yang berukuran 1x0,75x1 m3 dengan volume air 0,6 m3 dan padat tebar 5 kg/m3 atau 10-12 ekor/kolam. Parameter yang diamati meliputi pertumbuhan mutlak, laju pertumbuhan relatif, rasio konversi pakan (FCR) dan kualitas air. Perlakuan kadar protein 26%, 27% dan 28% menghasilkan pertumbuhan mutlak yaitu 73,59±9,65 g, 70,53±14,29 g, dan 90,08±12,42 g, laju pertumbuhan relatif yaitu 2,04±0,28 %/hari, 1,63±0,21 %/hari, dan 2,21±0,01 %/hari, dan rasio konversi pakan yaitu 2,16±0,09, 2,08±0,9, dan 1,95±0,14. Hasil penelitian menunjukkan bahwa kadar protein 26%, 27% dan 28% dalam pakan tidak memberikan pengaruh yang nyata antar perlakuan terhadap pertumbuhan mutlak, laju pertumbuhan relatif dan rasio konversi pakan gurami.

The aims of this study were to determine the effects of protein content in feed on growth of giant gouramy (Osphronemus goramy). This study was conducted during May-August 2020 at the Experimental Pond of the Department of Fisheries, Faculty of Agriculture, Universitas Gadjah Mada. The treatment wear feeding with different protein levels of 26%, 27% and 28% by using with three replications. The frequency of feeding was once a day at 13.00, ad satiation. The effect of protein levels were observed from the growth and feed conversion ratio for 10 weeks of observation. 250-350 g gouramy were maintained in concrete pond sized 1x0.75x1 m3 with 0.6 m3 water volume and 5 kg/m3 stocking density or 10-12 individuals/pond. Observed parameters included absolute growth, relative growth rate, feed conversion ratio (FCR) and water quality. Absolute growth resulted in the treatment of protein content of 26%, 27% and 28%, namely 73.59±9.65 g, 70.53±14.29 g, and 90.08±12.42 g, the relative growth rates produced were 2.04±0.28 %/day, 1.63±0.21 %/day, and 2.21±0.01 %/day, and feed conversion repressively were 2.16±0.09, 2.08±0.9, and 1.95±0.14. The results showed that protein content of 26%, 27% and 28% in feed did not have a significant effect between treatments on absolute growth, relative growth rate and feed conversion ratio of gouramy.
