Color is one of the indicators of quality in ornamental fish. This study aims to test the carotenoid content in butterfly pea leaves as a source of natural pigment and its effect on the tail color quality of green swordfish. Research was carried out using a Completely Randomized Design (CRD) consisting of 4 treatments and 3 replications. The four treatments were carried out by adding 0, 1, 6 and 12% of butterfly pea leaf flour in the feed. The parameters observed in this study were including carotenoid content of dried butterfly pea leaves, changes in color quality of the green swordfish tail, survival, and water quality. The color observations data were analyzed using the Kruskal-Wallis analysis, if there were differences between treatments, a multiple comparison was performed using the Z test with a 95% confidence level. Survival data were analyzed using analysis of variance using the F test with a 95% confidence level, if there were differences between treatments, the test then followed by the Duncan test with a 95% confidence level. The results showed that there were 9067 mg / kg of carotenoid contained in dried butterfly pea leaves. The addition of 12% butterfly pea leaf flour to commercial feed was able to improve the color quality on the tail of the green swordfish with an average color score of 5 and a color value of 87.3. Addition of carotenoids in feed does not significantly affect survival, and water quality. These results indicated that the use of butterfly pea leaves is safe to use as a source of natural pigment for ornamental fishes, such as swordfish.
