PENENTUAN KOMBINASI TERBAIK PAKAN BUATAN DARI LIMBAH LELE TERHADAP PERTAMBAHAN BERAT IKAN LELE DUMBO (CLARIAS GARIEPINUS) DENGAN EKSPERIMEN RANCANGAN ACAK LENGKAP

Abstract

In catfish farming biggest obstacle is the high cost of feed that is 70% of the total cost of production. Under these conditions, it is necessary the development of feed protein source local raw materials are easily available and have the appropriate nutrients in lieu of mill feed. One of the raw materials that can be used as an alternative is a waste of catfish. The rest of the processing waste is produced catfish processing industry. This study aims to find the best combination of artificial feed to gain catfish through a completely randomized design experiments and economic analysis of selected artificial feed. Treatment in the form of a concentration difference waste of catfish plus bran. Treatment I(90% waste +10%bran), treatment II(85% waste +15%bran), treatment III(80% waste +20% bran), treatment IV(75% waste +25% bran). Given feed 2 times a day as much as 5% of total body weight. Tests conducted on catfish 2 month old in a tub at a density of 5 trials tail / tub and 6 replicates for 1.5 months. The results obtained by the combination treatment was chosen III(80%waste +20%bran), with the highest average growth of 39.57 g/fish. Economic analysis of selected artificial feed production capacity of 100 kg/month obtained artificial feed production cost is Rp 2838.33/kg. Feed prices have made the difference between Rp 5,161 to the mill feed is sold at Rp 8,000.00/per kg. Key words: artificial feeding, Clarias gariepinus, completely randomized design experiment, waste of catfish
