Abstract

Utilization of agroindustrial byproduct as cheap raw materials for aquafeed was hampered by its poor nutritional value as well as high antinutrition content which could be overcome through fermentation. Coconut testa (CT) and cassava bagasse (CB) were mixed, and fermented using Rhizopus oryzae for preparing aquafeed. Subsequent feeding test was carried out on tilapias (Oreochormis niloticus L.) using 5 feeding treatments: one unfermented feed (commercial feed 100%), and the other four feeds produced by fermentation using substrate mixture of CT and CB in 4 different ratios, namely 100%:0%, 75%:25%, 50%:50%, and 25%:75%. Feeding 100% commercial feed (true protein 22.64% and crude fibre 14.67%) showed the best results on the fish growth with body weight gain of 3.96 g and feed conversion ratio of 8.63. Meanwhile, feeding fermented feeds (true protein 7.96-20.27% and crude fiber 14.14-18.47%) resulted in body weight gain in the range of 2.22 to 2.75 g with feed conversion ratio of 10.89 to 13.62. Thus, the fermented feeds promoted growth in tested tilapias albeit less optimally than commercial feed did.Keywords: Rhizopus oryzae, Oreochromis niloticus, coconut testa, cassava bagasse, fermentation ABSTRAKPenggunaan hasil samping agroindustri sebagai bahan pakan murah ikan terkendala rendahnya nutrisi dan tingginya antinutrisi yang dapat diatasi melalui fermentasi. Dalam penelitian ini, kulit daging buah kelapa (KK) dan onggok singkong (OS) dicampur dengan perbandingan tertentu, lalu difermentasi menggunakan Rhizopus oryzae untuk pakan ikan. Uji pemberian pakan dilakukan terhadap ikan nila (Oreochormis niloticus L.) dengan 5 perlakuan: satu perlakuan pakan tanpa fermentasi (pakan komersial 100%), dan empat perlakuan pakan fermentasi substrat campuran KK dan OS dengan 4 perbandingan yang berbeda, yakni 100%:0%, 75%:25%, 50%:50%, dan 25%:75%. Pemberian pakan komersial 100% (protein sejati 22,64% dan serat kasar 14,67%) memperlihatkan hasil terbaik pada pertumbuhan ikan nila dengan pertambahan bobot badan 3,96 g dan rasio konversi pakan 8,63. Sebaliknya, pemberian pakan fermentasi (protein sejati berkisar 7,96-20,27% dan serat kasar 14,14-18,47%) menghasilkan pertambahan bobot badan ikan pada kisaran 2,22-2,75 g dengan rasio konversi pakan 10,89-13,62. Dengan demikian pakan fermentasi tersebut mendorong pertumbuhan ikan nila namun kurang optimal dibandingkan pakan komersial.Kata Kunci: Rhizopus oryzae, Oreochromis niloticus, kulit daging buah kelapa, onggok, fermentasi

Abstract

Being the world’s third largest producer of cocoa (Theobroma cacao), Indonesia provides abundant cocoa pod husk byproduct. Despite its high content of biological materials, its use as animal feed, however, has been limited due to its low nutritive values and significant content of antinutritive substances. Thus, this study was aimed to investigate the changes of selected amino acids glutamate, aspartate, valine, alanine, and proline, as well as the antinutritional compound theobromine in cocoa byproduct-rice bran mixed substrate following fermentation using Rhizopus oryzae. The fermented substrate obtained had its true protein content increased from 1.95% to 23.16%. After analyses using ultra-performance liquid chromatography quadrupole time of flight mass spectrometry, the following amino acids, namely: total and free glutamates, total and free valine, total proline, as well as free alanine underwent increase, while the others decreased. The concentration of the antinutritional factor theobromine was below the limit detectable by HPLC.Keywords: Rhizopus oryzae, Theobroma cacao, theobromine, fermentation, amino acidsABSTRAKSebagai penghasil kakao (Theobroma cacao) terbesar ketiga di dunia, Indonesia mempunyai hasil samping melimpah berupa kulit cangkang kakao. Meskipun kandungan bahan biologisnya tinggi, penggunaan produk samping ini sebagai pakan ternak masih terbatas karena nilai gizi yang rendah serta kandungan zat antinutrisi yang tinggi. Oleh karenanya, penelitian ini bertujuan mengetahui perubahan kandungan asam amino glutamat, aspartat, valin, alanin, dan prolin, serta senyawa antinutrisi teobromin dalam campuran hasil samping coklat-dedak padi pasca fermentasi menggunakan Rhizopus oryzae. Substrat hasil fermentasi mengalami peningkatan kandungan protein sejati dari 1,95% menjadi 23,16%. Hasil analisis menggunakan ultra-performance liquid chromatography quadrupole time of flight mass spectrometry, menunjukkan bahwa kandungan asam amino: glutamat total dan glutamat bebas, valin total dan valin bebas, prolin total, serta alanin bebas mengalami peningkatan, sementara asam amino selainnya mengalami penurunan. Kandungan antinutrisi teobromin berada di bawah ambang batas deteksi oleh HPLC.Kata kunci: Rhizopus oryzae, Theobroma cacao, teobromin, fermentasi, asam amino

Abstract

Physical Characteristics of Non-Extruded Floating Fish Feed Produced through Rhizopus oryzae Fermentation ABSTRACTTo reduce the feed production cost of floating fish feed, an innovative method which is cheaper, easier, and simpler compared to the use of extruder machine is needed to provide buoyancy to fish feed. This research was conducted to determine the physical characteristics of floating fish feed prepared through fermention using Rhizopus oryzae on the mixed substrate consisting of commercial sinking fish feed, cassava bagasse, and Lemna minor. The resulting fermented feed was subsequently compared with commercial sinking fish feed in terms of its water stability, absorption, and floatability. The water stability curves of both feed types showed a similar pattern for 20 hours. Both decreased dramatically in the first 0.5 hours, from 100% to 81% for the fermented feed, and to 83% for the commercial feed. The shape of a 40-minute water absorption curve for both feed types was very similar. The fermented feed absorbed water nearly 4 times its initial dry weight, while commercial feed up to about twice as much as its initial dry weight. For three hours, both fermented and commercial floating pellets stayed afloat 100% without sinking. Thus, fermentation using R. oryzae deserves further development as an alternative way to provide buoyancy to fish feed.Keywords: floatability, floating feed, sinking feed, water absorption, water stability ABSTRAKUntuk menekan biaya produksi pakan ikan apung, diperlukan inovasi pengapungan pakan ikan yang lebih murah, mudah, dan sederhana dibandingkan dengan penggunaan mesin ekstruder. Penelitian ini dilakukan untuk mengetahui karakteristik fisik pakan apung hasil fermentasi menggunakan kapang Rhizopus oryzae pada substrat campuran pakan tenggelam komersial, onggok, dan Lemna minor. Pakan fermentasi ini lalu dibandingkan dengan pakan apung komersial dalam hal stabilitas dalam air, absorbsi air, dan daya apung. Stabilitas dalam air kedua jenis pakan memiliki pola yang mirip selama 20 jam. Stabilitas keduanya menurun drastis pada 0,5 jam pertama, dari 100% ke 81% untuk pakan apung fermentasi, dan ke 83% untuk pakan apung komersial. Bentuk kurva absorpsi air selama 40 menit untuk kedua jenis pakan sangatlah mirip. Pakan apung fermentasi menyerap air hampir 4 kali bobot kering awalnya, sedangkan pakan apung komersial hingga sekitar 2 kali bobot kering awalnya. Selama tiga jam, baik pakan apung fermentasi maupun komersial mengapung 100% tanpa tenggelam. Jadi, fermentasi menggunakan R. oryzae layak dikembangkan lebih lanjut sebagai cara pengapungan alternatif pakan ikan.Kata Kunci: daya apung, daya serap air, stabilitas dalam air, pakan apung, pakan tenggelam
