The cultivation of tubifex worms (Tubifex sp) traditionally utilizes nearly 100% organic materials as the growing medium; however, this approach has not yielded optimal biomass compared to the use of fermented organic materials. This study aims to evaluate the effectiveness of fermented media in enhancing the population density and biomass of tubifex worms. The study employed a Completely Randomized Design (CRD) with three treatments and four replications. The treatments consisted of different combinations of fermented organic materials, specifically cow manure and tofu waste, with varying proportions in each treatment. Measurements of population density and biomass were conducted after a specified rearing period. The cultivation was carried out in locations proximate to water sources to ensure optimal environmental conditions. The findings indicated that the use of combined fermented organic materials significantly affected the population density and biomass of tubifex worms (Tubifex sp). Treatment A demonstrated the highest population density and biomass, reaching 44.675 grams. These results suggest that fermented media provide a more conducive environment for the growth and reproduction of tubifex worms compared to non-fermented media. The application of fermented media composed of cow manure and tofu waste effectively enhances the population density and biomass of tubifex worms (Tubifex sp). Additionally, conducting cultivation near reliable water sources is crucial for supporting optimal worm growth. Future cultivation practices are recommended to incorporate fermented media and ensure adequate water availability to achieve maximum yield.

The demand for ornamental fish is increasing every year, one of the most popular ornamental fish is comet fish. Feed is a very important factor in supporting the quality of comet fish produced. In terms of improving the color quality of comet fish, the feed given must contain karatonoid as a color-forming content of comet fish. Moringa leaves are one of the ingredients that contain karatoneids and are an alternative pigmentation factor for ornamental fish. Feeding dosage is also a factor that needs to be considered in the maintenance of comet fish. Feed raw materials that have been formulated are first weighed one by one to match the feed formulation that has been determined. This study was conducted for 42 days by measuring the growth and brightness of fish color once a week. Feeding was carried out 3 times a day, namely in the morning, afternoon, and evening with a dose of feeding in each treatment of 10%, 15%, 20%, and 25%. This study used a complete randomized design. The results showed that the average change in fish body length during the observation of each treatment experienced an increase during maintenance, where the highest treatment was in treatment D by 1.69 cm. Observation of absolute weight is a parameter observed to determine the effect of feed containing moringa flour on comet fish. The highest average absolute weight growth rate at the end of the study was in treatment D amounting to 2.63 gr.
