Abstract

Catfish (Clarias gariepinus) has main benefit of its rapid growth. To optimize the growth of catfish, the feed must be considered. The use of commercial feeding for catfish has already been a common practice. Therefore, using existing feed raw materials or homemade food for the catfish is necessary. Vegetable waste such as cabbage and tofu dregs can be used as such food, which is processed into pellets. This is because cabbage waste, tofu dregs, rebon and mixed bran contain protein and carbohydrates that can be used for the fish growth. This study consisted of two steps: step1, analyzing the comparison between commercial feeding and the homemade feeding, and step 2, analyzing dosage difference of homemade catfish food and its effect on the growth of the catfish, and also its usage efficiency. Data were analyzed using unpaired t-test ANOVA test for two sample groups. The results showed that commercial feed and homemade feed had no significant effect on the length, weight and feed efficiency of catfish seeds. Catfish can be given homemade feed with ingredients from fermented cabbage waste, tofu dregs flour, rebon flour, bran flour, plus vitamins and minerals. The results of the analysis of various treatments for different feed dosages (4%, 5%, 6%, 7%, and 10% per body weight of fish, respectively) had a significant effect on length and weight growth of catfish, and no significant effect on feed efficiency. The study also found that the higher the dose is given for the maintenance of 30 days of catfish, the better effect is obtained, with the best dose of 10% per fish body weight
