Abstract

Impact of Slicing and Moulding Techniques on the Floatability of the Fish Feed Fermented by Rhizopus sp.ABSTRACTThe use of Rhizopus sp. mycelium as biocoating, biostabilizing, and biofloating agent in the production of floating fish feed through solid fermentation had already been studied as a much simpler alternative to mechanical extrusion. The fermented fish feed, however, had poor floatability in aerated water, probably due to structural damage during the size reduction process of the feed. Thus, this study used alternative size-reducing methods, namely slicing and moulding, to improve the floatability of the fermented feed. Other physical characteristics were also measured and compared to those of commercial sinking and floating fish feeds. Results showed that both the moulded and the sliced fermented-feeds had lower density as well as higher water stability, absorption capacity, floatability, and durability compared to those of the commercial sinking feed used as the fermentation substrate. The hydrophobicity of all the feeds tested were similar, however. The floatability of the fermented feeds obtained in this study was much higher than those of the previous studies. Keywords: floatability, floating feed, sinking feed, water absorption, water stabilityABSTRAKPenggunaan miselium Rhizopus sp. sebagai pelapis permukaan, penstabil, dan pengapung hayati dalam pembuatan pakan ikan apung melalui fermentasi padat telah diteliti sebagai alternatif yang jauh lebih sederhana dibandingkan dengan metode ekstrusi mesin. Namun, pakan ikan fermentasi ini memiliki daya apung yang buruk dalam air bergelembung udara, yang mungkin disebabkan kerusakan struktural selama proses pengecilan ukuran pakan. Karenanya, penelitian ini menggunakan metode lain untuk mengecilkan ukuran, yakni pencetakan dan pengirisan, dalam rangka meningkatkan daya apung pakan yang difermentasi. Karakteristik fisik lainnya juga diukur dan dibandingkan dengan pakan ikan tenggelam dan terapung komersial. Hasil menunjukkan bahwa proses fermentasi serta metode pengecilan dimensi yang digunakan menghasilkan pakan yang memiliki massa jenis lebih rendah, serta stabilitas air, daya serap air, daya apung, serta ketahanan benturan lebih tinggi dibandingkan dengan pakan tenggelam komersial yang digunakan sebagai substrat fermentasi. Namun, nilai hidrofobisitas semua pakan yang diuji adalah sama. Daya apung pakan fermentasi dalam penelitian ini jauh lebih tinggi daripada penelitian sebelumnya.Kata Kunci: daya apung, daya serap air, stabilitas dalam air, pakan apung, pakan tenggelam

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.Kata Kunci: Rhizopus oryzae, Cyprinus carpio, rice bran, coconut bagasse, fermentation  ABSTRACTRice 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.Keywords: Rhizopus oryzae, Cyprinus carpio, dedak, ampas kelapa, fermentasi
