چکیده

ABSTRAK Ikan guppy (P. reticulata) merupakan salah satu ikan hias air tawar yang banyak diminati karena variasi warna dan corak siripnya beragam. Warna dipengaruhi oleh sel pigmen pada tubuh. Pigmen tersebut dihasilkan dari penambahan karotenoid pakan. Salah bahan penghasil adalah tepung bunga marigold. Penelitian ini bertujuan untuk mengkaji pengaruh mengetahui dosis terbaik marigold dalam pakan buatan terhadap peningkatan kecerahan guppy. Variabel diamati antara lain bobot mutlak, rasio konversi pakan, laju pertumbuhan spesifik kelulushidupan. dengan 0,19 ± 0,03 g diperoleh pembudidaya Sleman, Yogyakarta. dilaksanakan di Galaksi Akuatik Indonesia, Semarang bulan Desember 2018-Januari 2019. menggunakan metode eksperimen rancangan acak lengkap (RAL) terdiri 4 perlakuan 3 kali ulangan. Perlakuan diterapkan A (0 mg/kg), B (25 C (50 mg/kg) D (75 mg/kg). Hasil penelitian menunjukkan bahwa berpengaruh nyata (P<0,05) tingkat guppy, namun tidak (P>0,05) (FCR), (SGR) kelulushidupan (SR). memberikan nilai tertinggi yaitu 4,05. Kesimpulan 50 mg/kg hasil reticulata). Kata Kunci : Guppy; Marigold; Pakan; Kecerahan Warna. ABSTRACT Guppy is one of the freshwater fish that has various colour with many type fin pattern.
