      Abstract
      Ikan sapu-sapu helikopter masih sedikit yang membudidayakan sehingga membuat ikan ini terus dicari oleh penyuplai ikan hias. Proyek akhir ini bertujuan untuk menentukan kepadatan tebar optimal ikan hias sapu-sapu helikopter (Sturisoma panamense) yang dipelihara dalam sistem resirkulasi. Perlakuan yang diuji adalah K (25) (tanpa resirkulasi dengan kepadatan 96 ekor/m²) sebagai kontrol, RAS (50) (resirkulasi dengan kepadatan 192 ekor/m²), dan RAS (75) (resirkulasi dengan kepadatan 288 ekor/m²). Hasil perlakuan menunjukkan bahwa perlakuan K (25) menghasilkan tingkat kelangsungan hidup (88,25%), pertumbuhan mutlak (PM) (2,37), dan laju pertumbuhan harian (0,11cm-1 ) tertinggi. RAS (50) mendapatkan nilai analisi usaha terbaik dibandingkan dengan perlakua K (25) dan RAS (75). Perlakuan RAS (50) terbukti efektif meningkatkan kepadatan tebar dengan sistem resirkulasi. Perlakuan RAS (50) memberikan hasil paling menguntungkan, dengan benih yang 72% (160 ekor) lebih banyak dibandingkan perlakuan K (25) dan 11% (28 ekor) lebih banyak dibandingkan perlakuan RAS (75). Perlakuan RAS (50) efektif dalam menaikkan padat tebar sebesar 50%. RAS (50) dapat menaikkan keuntungan berdasarkan hasil analisis usaha yang didapat.
       
      There are still a few helicopter fish that are cultivated so this fish continues to be sought after by ornamental fish suppliers. This study aims to determine the optimal stocking density of helicopter fish (Sturisoma panamense) reared in a recirculation system. The treatments tested were K (25) (no recirculation with a density of 96 fish/m²) as control, RAS (50) (recirculation with a density of 192 fish/m²), and RAS (75) (recirculation with a density of 288 fish/m²). The results showed that treatment K (25) produced the highest survival rate (88.25%), absolute growth (PM) (2.37), and daily growth rate (0.11cm-1). RAS (50) obtained the best effort analysis value compared to the K (25) and RAS (75) treatments. The RAS (50) treatment effectively increased stocking density with a recirculation system. The RAS (50) treatment gave the most profitable results, with 72% (160 fish) more seeds than the K (25) treatment and 11% (28 fish) more than the RAS (75) treatment. The RAS (50) treatment effectively increased stocking density by 50%. RAS (50) can increase profits based on the results of the business analysis obtained.
