Abstract

Color is one of the reasons ornamental fish are in demand by the community, so farmers need to maintain the color of ornamental fish. This study aims to determine the effect of carrot juice on the color of goldfish. This research was conducted from December to January 2023. The method used was an experimental method with Complete Randomized Design (RAL) with four treatments and three repeats in each test group. Testing is carried out by giving feed with a mixture of carrot juice with different doses. The results showed that the color values in goldfish were different, namely, P0 treatment without giving carrot juice with a color value of 18.54, P1 treatment (10 g/100 ml aquades) with a color value of 18.4, P2 treatment (20 g/100 ml) with a color value of 19.35, P3 treatment (30 g/100 ml) with a color value of 17.67. Analysis of Variance (ANOVA) showed that the effect of carrot juice on the color of goldfish had no significant effect on each treatment with FHitung (0.11) > FTabel (4.07). Water quality parameters during the study were still in normal conditions for the growth of goldfish.

Abstract

Tilapia is a fish species in Indonesia with significant economic value. Tilapia cultivation has excellent prospects, both domestically and internationally, requiring effective measures to ensure production meets community standards. The prospects for developing tilapia cultivation are quite promising, as the low production costs of tilapia farming allow for higher profits. Biofloc technology is an alternative solution to the waste problem of intensive farming. This technology is highly advantageous because it not only reduces inorganic nitrogen waste from leftover feed and feces, but also provides supplemental protein feed for farmed animals, thereby increasing growth and feed efficiency.This study aims to analyze the benefits and factors that influence the success of tilapia biofloc cultivation in SikoFish Gorontalo. This study uses a quantitative method with data collection techniques through surveys and observations. The results of the study indicate that tilapia biofloc cultivation can generate profits of Rp. 180,585,000 / harvest with a return on investment of 1.14 years. Factors that influence the success of tilapia biofloc cultivation are location selection, container preparation, media preparation, seed preparation, seed distribution, feed management, water quality management, and floc density. Therefore, it is necessary to develop business and production cost efficiency to increase income and make tilapia biofloc cultivation viable.
