Abstract

Ikan badut Premnas biaculeatus hasil biakan atau budidaya cenderung mengalami degeneratif warna atau memiliki warna tubuh yang pudar tidak seperti habitat alami. Penelitian ini bertujuan untuk meningkatkan kecerahan warna ikan badut melalui penambahan tepung buah yang mengandung ?-karoten pada pakan. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) 4  perlakuan 5 ulangan. Pemberian pakan ikan badut dengan Kontrol (tanpa penambahan tepung), perlakuan A (tepung labu kuning) B (tepung wortel) dan C (tepung ubi jalar ungu) dengan dosis masing-masing 15% (15g/100g pakan). Ikan yang digunakan berukuran panjang dan berat masing-masing  ± 3 cm dan ± 0,5 g. Padat tebar 1 ekor/soliter dan jumlah ikan 20 ekor. Parameter perubahan warna badan merah menunjukkan hasil yang terbaik pada perlakuan B (tepung wortel 15%) dengan nilai R (-14,1± 4,1), G (-16,1±3,8) dan B (-9,3± 5,8). Parameter perubahan warna badan putih diperoleh perlakuan terbaik pada kontrol (tanpa penambahan tepung) dengan nilai R (28,3±0,8), G (34,5±3,1) dan B (28,5±1,0). Parameter laju pertumbuhan bobot mutlak dan panjang mutlak terbaik terdapat pada perlakuan B (tepung wortel 15%) dengan nilai berturut-turut adalah (0,324±0,01) dan (0,64±0,05). Parameter tingkat kelangsungan hidup mendapatkan nilai (100±0,00).

Abstract

An important aspect in tilapia cultivation is observing the relationship between the length and weight of the fish, which is an indicator of the fish's growth. One of the areas in West Nusa Tenggara that has great potential in tilapia cultivation is Gerung which is located in West Lombok Regency. The purpose of this study is to determine the growth pattern of tilapia in the region to help farmers adjust feed management, stocking density and maintenance systems to increase production. The method used is the survey method and regression analysis. The number of samples used in this study were 16 tilapia (Oreochromis niloticus) taken randomly from tilapia rearing ponds in Gerung District, West Lombok Regency. The average weight obtained in this study ranged from 169-400 grams with an average of 285 grams and a length of 25-39 cm, while the results of statistical regression of the relationship between the length and weight of tilapia, the regression equation obtained a value of Log Y = 25.419X 0.7394 with a correlation value (R2) of 43% and a value of b = 0.73, so that b <3 which means negative allometric where the condition of the fish experiences faster growth in length than weight gain
