Abstract
Goldfish is one of the most famous ornamental fish because of body shape and the color which is interesting to culture. The purpose of this experiment is to find the effect of Spirulina platensis and carrot meal was added into feed to increase the red color of koki goldfish. The experiment used Completely Randomized Design with six treatments and three replication. The treatments is 8% Spirulina meal, 8% carrot meal, 0% spirulina meal + carrot meal, 2%+6%, 4%+4%, and 6%+2%. The parameters that observed is color intensity, absolute weight growth, and water quality. The results showed that supplementation of combination 4% spirulina meal and 4% carrot meal gave the best increase in red color on body of koki goldfish with average score 5.93, but no significant effect on growth of goldfish with average growth is 3.55 ± 0.06 gram. Water quality during the research is still in optimal condition and did not affect the enhancement color in goldfish.

Summary
Penelitian ini menggunakan beberapa alat seperti 16 akuarium (30x20x20 cm3), selang, blower, DO meter Lutron + Termometer, pH meter Digital Instrumen, Timbangan Scout Pro, dan Toca Colour Finder. Bahan yang digunakan pada penelitian ini adalah Ikan koki jenis oranda berumur 3 bulan dengan rata-rata panjang 5±0.02 cm, pakan komersil (protein 39%, lemak 5% dan serat 4%), tepung spirulina, dan tepung wortel. Selama penelitian frekuensi pemberian pakan 2 kali sehari pada jam 08.00 WIB dan jam 16.00 WIB. Jumlah pakan akan disesuaikan setiap 10 hari berdasarkan pertambahan bobot ikan setelah dilakukan sampling. Pengamatan kecerahan warna dilakukan secara visual dengan menggunakan standar nilai dari Toca Colour Finder. Pengamatan warna, bobot ikan, dan kualitas air dilakukan setiap 10 hari sekali selama penelitian
