      Abstract
      Ikan koi merupakan salah satu ikan hias yang cukup digemari oleh masyarakat di Indonesia. Penurunan kualitas warna menjadi kendala dalam budidaya ikan koi kohaku Cyprinus rubrofuscus. Salah satu upaya peningkatan warna adalah melalui pemberian pakan tambahan mengandung karotenoid dari bahan alami seperti spirulina dan wortel. Penelitian ini bertujuan untuk menentukan bahan terbaik dalam meningkatkan kecerahan warna koi. Metode yang digunakan adalah Rancangan Acak Lengkap dengan empat perlakuan: pakan kontrol, spirulina 3%, wortel 3%, dan kombinasi spirulina-wortel 3%. Ikan koi kohaku dengan ukuran 5–6 cm dipelihara selama 40 hari dan parameter yang diamati meliputi kecerahan warna menggunakan Toca Color Finder (TCF), pertumbuhan, kelangsungan hidup, grading, dan analisis ekonomi. Hasil menunjukkan bahwa perlakuan spirulina 3% memberikan skor kecerahan warna tertinggi (22,37) dengan hasil grade A sebanyak 14,3%, serta keuntungan ekonomi terbesar dengan payback period tercepat (0,26 tahun). Penambahan spirulina terbukti efektif dalam meningkatkan nilai estetika dan ekonomi ikan koi kohaku
       
      Koi fish are among the most popular ornamental fish in Indonesia. However, color degradation poses a challenge in the cultivation of Kohaku koi Cyprinus rubrofuscus. One approach to enhance coloration is through dietary supplementation with natural carotenoid sources such as spirulina and carrot. This study aimed to determine the most effective natural ingredient in improving color brightness in koi. A Completely Randomized Design (CRD) was employed with four treatments: control feed, 3% spirulina, 3% carrot, and a 3% spirulina-carrot combination. Kohaku koi measuring 5–6 cm were cultured for 40 days. Observed parameters included color brightness using the Toca Color Finder (TCF), growth, survival rate, grading, and economic analysis. The results indicated that the 3% spirulina treatment produced the highest color brightness score (22.37), with 14.3% of fish reaching grade A. It also yielded the highest economic return with the fastest payback period (0.26 years). Spirulina supplementation proved effective in enhancing both the aesthetic and economic value of kohaku koi
