Koi fish (Cyprinus carpio haematopterus) is one type of ornamental fish. Koi fish that have beautiful colors and shapes and bright can be high selling value. Color is one of the reasons for ornamental fish demand by the community. Koi fish can not produce their own color pigments to enhance the beauty of their skin. The effort made to obtain color enhancement is to add a pigment source to the feed, for example, Carrot Flour and Pumpkin. The purpose of this research is to know the effect of carrot flour mixture (Daucus carota D) and pumpkin flour (Cucurbita moshata L) to Koi fish color. The study used Completely Randomized Design (RAL) with four treatments and three replications. Treatment 1 (P0) with pelleting, Treatment 2 (P1), combination between the pellet and 30% Carrot flour. P2 is a combination of pellet and 30% pumpkin flour. P3 is a combination of 30% pellets and 70% yellow pumpkin flour and Carrots with a ratio of 1: 1. Parameters in this study include color change, fish growth, and water quality. The research was conducted for 30 days with 2 observations, namely the 15th and 30th days. The results of the research were tested using the Analysis of Variety Sidik (ANSIRA). If there is a difference between median treatment values, then proceed with DMRT test to know the best treatment. The result of ANSIRA test showed that there was a significant effect on the addition of carrot and pumpkin flour to the increase of Koi fish color. DMRT test results showed that at day 15 there was no difference in treatment effect between P1, P2, and P3. On the 30th day, P3 showed the best effect.
