Abstract
Artificial feeding feeding is given asadditional feed to accelerate the process of fishenlargement. Self-processing of feed can beconducted by utilizing cow manure through thefermentation process and the addition of aneffective microorganism (EM4) solution. Thisresearch used 3 treatments which arefermentation for 5, 9, 11 days with each drycow manure of 2 kg with water content of 19%.The resulting feed was then tested for qualityto determine protein and fat content. The 3treatments produced levels of nutrient proteinand fat as follows: protein levels in treatment I(6.16%), II (7.57%), III (7.68%) while the fatcontent in treatment I (0.15 %), II (0.50%), III(0.60%). The results of feed from alltreatments were given to catfish. Catfishgrowth was observed for 10 days. Weight gainfrom the initial weight of 400 gr, on treatment1 to the 10th day: 500 grams, the secondtreatment to the 10th day weighing 600 grams,treatment 3 to the 10th day: 1000 grams.Resulted feed haven’t met Quality Standardsfor SNI Feed No SNI: 01-4087-2006.
Highlights
Feeding is an important component as fish energy in doing activities and grow
After the fermentation process of organic catfish feed, it was tested for fat and protein content at the Baristand Laboratory in Surabaya
The addition of EM4 cow manure to produce organic catfish feed highly affects the process of breaking down nutrient components in cow manure into protein and fat
Summary
Feeding is an important component as fish energy in doing activities and grow. In nature, fish can meet their food needs with feed available in nature. Cow manure can be used as artificial feed for catfish by processing a kind of organic fertilizer that will stimulate the growth of natural feed as well as the media for the development of complex microorganisms in catfish ponds (Anonymous, 2013). In the previous research conducted by Agus Priyanto (2011), he utilized the use of biogas waste (sludge) as a substitute for pellet feed, from the results of research at the Quality Hall of Fish Feed Testing (BPMT) producing Protein (Rough 7.83%), Fat (crude 3.28%). After the fermentation process of organic catfish feed, it was tested for fat and protein content at the Baristand Laboratory in Surabaya. 3. Result and Discussion The use of raw material for dumbo catfish feed from expired processed human food ingredients caused debate for consumers of farmer-made feed products. Based on the quality requirements of artificial fish feed, the resulting feed does not meet the quality standards of artificial feed
