ABSTRACT
Color is a primary factor that makes fish highly desirable. The appearance of color is due to the presence of pigment cells or chromatophores within the fish’s body. Feed significantly influences the enhancement of color brightness in fish. One essential component is the red dragon fruit skin flour, which serves as a natural source of carotenoids. This research aims to determine the impact of adding the optimum concentration of red dragon fruit skin flour in artificial feed to enhance the color brightness of Sumatra fish (Puntigrus tetrazona). The materials used during the study include Sumatra fish measuring 2-3 cm, red dragon fruit skin flour, CMC (Carboxymethylcellulose), specialized ornamental fish feed, and commercial feed. The experimental method employed a Completely Randomized Design with five treatments and three replications consisting of Treatment (A) Commercial feed without red dragon fruit skin flour (negative control), (B) Commercial feed with the addition of 12.5% red dragon fruit skin flour, (C) Commercial feed with the addition of 15% red dragon fruit skin flour, (D) Commercial feed with the addition of 17.5% red dragon fruit skin flour, (E) Commercial feed with improved color formula without using red dragon fruit skin flour (positive control). Color brightness observations were analyzed using the Kruskal-Wallis test, and if there was a significant difference, a post hoc test (Z-test) was performed. The research results showed that the enhancement of color in the head, dorsal fin, and tail fin of Sumatra fish on day 30 exhibited the highest values in the treatment with the addition of 15% red dragon fruit skin flour, with an average score of 0.31 for the head, 2.60 for the dorsal fin, and 1.31 for the tail fin. The optimum concentration for the addition of red dragon fruit skin flour for the best enhancement of color brightness was found to be 15%.
