Penggunaan Tepung Bunga Marigold (Tagetes erecta L.) dalam Pakan terhadap Kualitas Warna dan Pertumbuhan Ikan Sumatra (Puntigrus tetrazona)
Abstract
Ikan sumatra (Puntigrus tetrazona) adalah ikan hias endemik yang berhasil dibudidayakan dan memiliki pola warna khas, namun seringkali kualitas warnanya rendah. Upaya peningkatan warna ikan hias dilakukan melalui pakan buatan dengan menambahkan tepung bunga marigold/TMG (Tagetes erecta L) sebagai sumber karotenoid sebanyak 0%, 2%, 4%, dan 6% pada pakan. Pemberian pakan dilakukan at satiation, 2 kali sehari. Parameter yang diukur pada penelitian ini yaitu kualitas warna dan kinerja pertumbuhan ikan. Hasil uji anova menunjukkan jumlah konsumsi pakan berbeda nyata (p<0,05). Kualitas warna berdasarkan nilai lightness dan hue berbeda nyata antar perlakuan (p<0,05), ter namun nilai chroma tidak berbeda nyata (p>0,05). Kelangsungan hidup dan pertumbuhan ikan menunjukkan tidak ada perbedaan antar perlakuan (p>0,05). Perubahan kualitas warna yang kontras ditunjukkan oleh ikan sumatra yang diberi pakan dengan TMG sebanyak 2%. Tiger barb (Puntigrus tetrazona) is an endemic ornamental fish that has been successfully cultivated and has a distinctive color pattern, but often the color quality is low. Efforts to increase the color of ornamental fish are carried out through artificial feed by adding marigold flower flour/TMG (Tagetes erecta L) as a source of carotenoids as much as 0%, 2%, 4%, and 6% to the feed. Feeding was done at satiation, 2 times a day. The parameters measured in this study were color quality and fish growth performance. The results of the ANOVA test showed that the amount of feed consumption was significantly different (p<0.05). Color quality based on lightness and hue values was significantly different between treatments (p<0.05), tar but chroma value was not significantly different (p>0.05). The survival and growth of fish showed no difference between treatments (p>0.05). Changes in contrasting color quality were shown by tiger barb fed with TMG as much as 2%.
