Ikan mas koki (carassius auratus) tergolong ke dalam ikan hias air tawar. ikan ini memiliki warna tubuh yang bervariasi sehingga banyak diminati oleh masyarakat. peningkatan kecerahan warna ikan hias dapat dilakukan dengan menambahkan sumber β-karoten pada pakan. tujuan penelitian untuk mengkaji pengaruh penambahan ekstrak buah pepaya dalam pakan untuk meningkatkan kecerahan warna pada ikan mas koki serta menentukan dosis terbaik. metode yang digunakan pada penelitian adalah rancangan acak lengkap (ral) dengan 5 perlakuan dan 3 ulangan yaitu p0 (tanpa penambahan ekstrak buah pepaya), p1 (penambahan ekstrak buah pepaya 10 ml/kg), p2 (penambahan ekstrak buah pepaya 20 ml/kg), p3 (penambahan ekstrak buah pepaya 30 ml/kg) dan p4 (penambahan ekstrak buah pepaya 40 ml/kg). hasil uji anova (analysis of variance) menunjukkan penambahan ekstrak buah pepaya pada pakan benih ikan mas koki berbeda nyata (p0,05) terhadap parameter pertumbuhan ikan mas koki. peningkatan warna tertinggi pada ikan mas koki (2,83%) diperoleh pada penambahan 30 ml/kg ekstrak buah pepaya pada pakan p3. hasil penelitian nilai pertumbuhan panjang mutlak sebesar 0,97-1,09 cm, pertumbuhan berat mutlak sebesar 0,23-0,34 gr, dan kelangsungan hidup sebesar 77,7-88,8%. penambahan ekstrak buah pepaya efektif untuk meningkatkan kecerahan warna tapi tidak berpengaruh terhadap pertumbuhan ikan mas koki. kata kunci: ikan mas koki, ekstrak buah pepaya, kecerahan, warna

Goldfish (Carassius auratus) belongs to the freshwater ornamental fish. The fish has a body color that varies so much in demand by the public. Increasing the color brightness of ornamental fish can be done by adding a source of β-carotene to the feed. The aim of the study was to examine the effect of adding papaya fruit extract to the feed to increase the brightness of the color of goldfish and to determine the best dose. The method used in this study was a completely randomized design (RAL) with 5 treatments and 3 replications, namely P0 (without adding papaya fruit extract), P1 (adding 10 ml/kg papaya fruit extract), P2 (20 ml/kg papaya fruit extract adding). ), P3 (addition of papaya fruit extract 30 ml/kg) and P4 (addition of papaya fruit extract 40 ml/kg). The results of the ANOVA (Analysis Of Variance) test showed that the addition of papaya fruit extract to the goldfish seed feed was significantly different (P0.05) in the growth parameters of the goldfish . The highest color increase in goldfish (2.83%) was obtained by adding 30 ml/kg of papaya fruit extract to P3 feed. The results of the research showed that the absolute length growth was 0.97-1.09 cm, the absolute weight growth was 0.23-0.34 g, and the survival rate was 77.7-88.8%. The addition of papaya fruit extract is effective in increasing the brightness of the color but has no effect on the growth of goldfish. Keywords: Goldfish, Papaya Fruit Extract, Brightness, Color
