Abstract


Dedak padi dan ampas kelapa dicampur dengan perbandingan tertentu dan kemudian difermentasi menggunakan Rhizopus oryzae untuk pakan ikan. Uji pemberian pakan lalu dilakukan untuk mengetahui pengaruh pakan terhadap pertumbuhan ikan mas (Cyprinus carpio L.). Dalam penelitian ini digunakan 5 perlakuan: satu perlakuan pakan tanpa fermentasi (pakan komersial 100%), dan empat perlakuan pakan fermentasi substrat campuran bekatul dan ampas kelapa dengan empat perbandingan yang berbeda, yakni 75%:25%, 50%:50%, 25%:75%, dan 0%:100%. Hasil penelitian menunjukkan bahwa pemberian pakan komersial 100% (protein sejati 15,25% dan serat kasar 6,27%) memperlihatkan hasil terbaik terhadap pertumbuhan ikan mas dengan pertambahan bobot badan 2,56 g dan rasio konversi pakan 1,95. Sementara itu pemberian pakan fermentasi (protein sejati berkisar 4,89-9,97% dan serat kasar 22,87-25,70%) hanya menghasilkan pertambahan bobot badan ikan pada kisaran 0,47-0,64 g dengan rasio konversi pakan 2,50-2,64. Dengan demikian pakan fermentasi tersebut mampu mendorong pertumbuhan ikan mas meskipun masih kurang optimal dibandingkan dengan pakan komersial.

ABSTRACT

Rice bran and coconut bagasse were mixed and then fermented using Rhizopus oryzae for preparing aquafeed. Subsequent feeding test was carried out to determine the effect on the growth of carps (Cyprinus carpio L). Five feeding treatments were employed, one unfermented feed (commercial feed 100%), and the other four feeds produced by fermentation using substrate mixture of rice bran and coconut pulp in four different ratios, namely 75%:25%, 50%:50%, 25%:75%, and 0%:100%. The results showed that feeding 100% commercial feed (true protein 15.25% and crude fibre 6.27%) showed the best results on the fish growth with body weight gain of 2.56 g and feed conversion ratio of 1.95. Meanwhile, feeding fermented feeds (true protein 4.89-9.97% and crude fiber 22.87-25.70%) only resulted in body weight gain in the range of 0.47 to 0.64 g with feed conversion ratio of 2.50 to 2.64. Thus, the fermented feeds promoted growth in tested carps albeit less optimally than commercial feed.
