Abstract

Firman Syarif Ibrohim, NPM 3220600013. The Influence of Tomato Flour (Solanum lycopersicum) and Pumpkin Flour (Cucurbita moschata D.) Addition in Feed on the Growth and Color Brightness of Koi Fish (Cyprinus carpio) (Advisor by Dr.Ir Suyono, M.Pi and Dra.Hj.Sri Mulatsih, M.Si) The aesthetic appeal of the coloration in Koi fish is a primary attraction for Koi enthusiasts. The selling price of Koi fish tends to be high due to the inherent beauty of their colors. Efforts to enhance the color clarity in these fish can be achieved through the supplementation of carotenoids in their diet. One of the carotenoids considered most effective for this purpose is Tomato Powder and Pumpkin Powder, owing to its ß-carotene content, which stimulates growth and enhances the color clarity of Koi fish. This research aims to assess the impact of Tomato Powder and Pumpkin Powder on the growth and color clarity of Koi fish (Cyprinus carpio). The research design utilizes a Completely Randomized Design (CRD) with three treatment groups (Tomato Powder 20%, Pumpkin Powder 20%, Tomato and Pumpkin Powder 40%), repeated three times. The Koi fish used have an initial size of 8 cm and a weight of 11 grams, placed in aquariums sized 50 x 25 x 25 cm with a density of 10 fish per aquarium. Observed parameters include the color score of Koi fish using the Toca Colour Finder (TCF), daily growth rate, absolute growth rate, survival rate, feed conversion ratio, feed efficiency, and water quality. The research results indicate a positive influence from the administration of Tomato Powder and Pumpkin Powder on the color clarity of Koi fish. The best treatment is achieved through the application of Tomato Powder and Pumpkin Powder at a dosage of 40%, resulting in an earlier one-score increase in color clarity by the third week of the study. However, the application of Tomato Powder and Pumpkin Powder at dosages of 20%, 20%, and 40% does not significantly affect the weight and length growth of Koi fish (Cyprinus carpio). Additionally, water quality parameters during the study remain within acceptable tolerance ranges. Keywords: Tomato, pumpkin, koi fish, fish color brightness.
