Abstract
The purpose of this research is to determine the optimal dose of the addition of red spinach powder to artificial feed on the brightness of clown loach. This research was conducted at Aquaculture Laboratory Building 4 Faculty of Fisheries and Marine Sciences of Universitas Padjadjaran from April to May 2020. This research method is experimental with a Completely Randomized Design consisting of four treatments and three replications. The red spinach powder addition treatment used 0%, 2%, 4%, and 6% of the feed amount. The parameters observed are color value as primary data by using Toca Color Finder, while the growth, survival rate, and water quality as support data. Color assessment results were analyzed using the Kruskal-Wallis test, if there were significant differences, Z test would be performed. Growth data and survival rates were analyzed using Analysis of Variance (ANOVA). Because the F test results were not significantly different, the Duncan test was not carried out. The results showed that the addition of 6% red spinach powder is the best treatment with an increased color brightness value of 5,63.
