Abstract

The study was conducted to investigate the effect of shrimp head meal and carrot meal in the diet on the skin coloration of maanvis (Pterophyllum scalare). Measurement of skin coloration was performed after the fish fed four kinds of diet treatment supplied with: 40 g shrimp head meal/100 g diet (Diet A); 40 g carrot meal/100 g diet (Diet B); 20 g shrimp head meal + 20 g carrot meal / 100 g diet (Diet C) and one diet without add pigment source as a control diet. The fish fed three times a day for 40 days rearing. Measurement of skin coloration of fish was done in two times (seventh day and thirty fifth day of rearing) by using score sheet. In the seventh day of experiment, the skin color of maanvis in all of groups showed dominantly of silver color (45-92%) followed by yellow color (3-9%). Black color of the fish in A and D groups were 5% and 8%, while the fish in B and C group were 48% and 37%. In the end of experiment, the skin color of fish fed diet contained pigment (diet A, diet B, and diet C) showed increasingly in black color (39-61%) and yellow color (12-19%), while silver color of the fish fed diet contained pigment were decreasing between 20-45%. In con-clusion, the shrimp head meal and carrot meal supplemented in the diet could improve the skin color of maanvis.


Abstrak


Penelitian ini dilakukan untuk mengkaji pengaruh tepung kepala udang dan tepung wortel sebagai sumber pewarna alami dalam pakan buatan terhadap warna ikan maanvis (Pterophyllum scalare). Penilaian persentase setiap jenis warna dan tingkat kecerahan warna ikan maanvis dilakukan setelah ikan uji diberi pakan yang mengandung tepung kepala udang dan tepung wortel dengan komposisi masing-masing perlakuan A (40 g tepung kepala udang per 100 g pakan), perlakuan B (40 g tepung wortel per 100 g pakan), perlakuan C (campuran 20 g tepung kepala udang dan 20 g tepung wortel per 100 g pakan), perlakuan D(kontrol) diberi pakan komersial dengan merek Takari selama 35 hari. Penilaian warna ikan maanvis dilakukan sebanyak dua kali yaitu penilaian awal (setelah 7 hari masa adaptasi pakan) dan penilaian akhir setelah 35 hari masa pemeliharaan. Penilaian warna ikan maanvis dilakukan dengan menggunakan Score Sheet yaitu suatu metode pengujian organoleptik berdasarkan warna dengan melibatkan panelis. Hasil penilaian menunjukkan bahwa persentase warna ikan maanvis pada awal penelitian pada semua perlakuan relatif didominasi oleh warna silver (berkisar 45-92%), warna kuning berkisar 3-9%, warna hitam pada perlakuan A dan D masing-masing 8% dan 5%, se-mentara warna hitam pada perlakuan B dan C masing-masing 48% dan 37%. Pada akhir penelitian, warna hitam dan kuning pada ikan maanvis yang diberi pakan perlakuan persentasenya meningkat masing-masing berkisar 39-61% dan 12-19% sedangkan warna silver persentasenya turun menjadi 20-45%. Hasil ini menyimpulkan bahwa pemberian kom-binasi tepung kepala udang dan tepung wortel dapat meningkatkan performa warna kulit ikan maanvis.
