      Abstract
      Ikan cupang giant merupakan jenis ikan cupang yang banyak diminati dan dapat diperoleh melalui perkawinan silang, namun keturunannya memiliki laju pertumbuhan yang lebih rendah dibandingkan dengan induknya. Hal tersebut dapat diatasi dengan pemberian hormon untuk meningkatkan laju pertumbuhan. Penelitian ini bertujuan mengidentifikasi efektivitas perendaman hormon tiroksin dan hormon pertumbuhan rekombinan terhadap pertumbuhan larva ikan cupang. Penelitian ini dilakukan dengan metode eksperimental menggunakan Rancangan Acak Lengkap (RAL) dengan 5 perlakuan: A, kontrol; B, 10 mg/L rGH; C, 0,05 mg/L T4 + 10 mg/L rGH; D, 0,1 mg/L T4 + 10 mg/L rGH; dan E, 0,15 mg/L T4 + 10 mg/L rGH dan 5 ulangan. Larva yang berumur 7 hari berukuran bobot rata-rata sebesar 0,043±0,001 g dan panjang rata-rata 5,721±0,001 mm dilakukan perendaman selama 24 jam dengan kepadatan 50 ekor/akuarium. Hasil terbaik terdapat pada perlakuan D yang dilihat dari parameter pertumbuhan berat mutlak (2,153 g), pertumbuhan panjang mutlak (35,388 mm), pertumbuhan panjang relative (6,297%) dan laju pertumbuhan harian (13,67%).
       
      Giant betta fish is a type of betta fish that is in great demand and can be obtained through cross-breeding, but the offspring have a lower growth rate than the parent. This can be supported by giving hormones to increase the growth rate. This study aims to identify the effectiveness of soaking the thyroxine hormone and recombinant growth hormone on the growth of Betta fish larvae. This research was conducted with an experimental method using a completely randomized design (RAL) with 5 treatments: A, control; B, 10 mg/L rGH; C, 0.05 mg/L T4 + 10 mg/L rGH; D, 0.1 mg/L T4 + 10 mg/L rGH; and E, 0.15 mg/L T4 + 10 mg/L rGH and 5 replications. 7 days old larvae with average 0,043±0,001 g of weight and 5,721±0,001 mm of length were soaked for 24 hours. The best results were found in treatment D as seen from the parameters of absolute weight growth (2.153 g), absolute length growth (35.388 mm), relative length growth (6.297%) and daily growth rate (13.67%).
