Purple sweet potato has the potential as a feed mixture ingredient to improve the color of ornamental fish, but it is not known how much the dose of purple sweet potato test extract in feed can increase the color of koi fish. Therefore, a study was carried out with the aim of knowing the effect of giving purple sweet potato extract in feed on color quality, total carotenoids, growth and survival of koi fish. This study used a completely randomized design consisting of five treatments and three replications, with the treatment of purple sweet potato extract in the feed. Giving purple sweet potato extract in commercial feed consisting of P0 (control) = without giving purple sweet potato extract, P1 = purple sweet potato extract 100 ml kg-1, P2 = purple sweet potato extract 150 ml kg-1, P3 = sweet potato extract purple 200 ml kg-1, and P4 = purple sweet potato extract 250 ml kg-1. The parameters measured in this study were color quality, growth and survival. The results showed that the feeding of purple sweet potato extract had a significant (p<.05) effect on the parameters of color quality, growth and survival, and not significant (p>.05) on the total carotenoids of koi fish. Thus, to improve the quality of color, growth and survival of koi fish, it is better to use feed with purple sweet potato extract of 250 mg kg-1 of feed.
