The study was conducted in the Ciparanje Green House, Faculty of Fisheries and Marine Sciences, Universitas Padjadjaran, Jatinangor. A completely randomized design with four treatments and three replications was applied, namely treatment A: Water circulation using bioball filter medium, B: Water circulation using water spinach filter medium, C: Water circulation using bioball and water spinach filter media, and D: Water circulation using sponge filter medium (control). The container used for the maintenance was a fiber tank at 70 cm × 70 cm × 70 cm size filled with 257 L water and a stocking density of 15 fish/fiber. The parameters observed were survival rate, growth, feed conversion, and water quality. The results showed that the use of biological filter using water spinach produced the best growth performance of catfish. The best survival rate was also obtained by using water spinach filter (100%) with the absolute growth of 98.32 ± 15.6 g. The water quality an aquaponic system with water spinach filter supported the growth performance of catfish fry.</p> <p>&nbsp;</p> <p>Keywords: absolute growth, aquaponic, <em>Clarias gariepinus</em>, filters.</p> <p>&nbsp;</p> <p><strong>ABSTRAK</strong></p> <p>&nbsp;</p> <p>Penelitian ini bertujuan untuk menguji efektivitas filter terhadap performa pertumbuhan benih ikan lele <em>Clarias gariepinus</em> dalam sistem akuaponik. Penelitian dilakukan di Laboratorium Rumah Kaca Ciparanje, Fakultas Perikanan dan Ilmu Kelautan, Universitas Padjadjaran, Jatinangor. Metode penelitian adalah rancangan acak lengkap dengan empat perlakuan dan tiga ulangan, yaitu perlakuan A: sirkulasi menggunakan media filter bioball, B: Sirkulasi menggunakan media filter bayam air, C: Sirkulasi menggunakan media filter bioball dan tanaman kangkung, dan &nbsp;&nbsp;&nbsp;D : Sirkulasi menggunakan media spons (kontrol). Wadah yang digunakan untuk pemeliharaan bak fiber dengan ukuran 70 cm × 70 cm × 70 cm diisi dengan air sebanyak 257 L dengan padat tebar 15 ekor / bak. Parameter yang diamati adalah kelangsungan hidup, pertumbuhan ikan, konversi pakan dan kualitas air. Hasil penelitian menunjukkan bahwa penggunaan filter biologis menggunakan tanaman kangkung menghasilkan &nbsp;performa pertumbuhan ikan lele yang terbaik. Tingkat kelangsungan hidup terbaik juga ditunjukkan oleh pelakuran dengan filter berupa tanaman kankung (100%) dan pertumbuhan mutlak 98,32 ± 15,6 g. Kualitas air sistem akuaponik dengan filter tanaman kangkung mendukung performa pertumbuhan benih ikan lele.&nbsp;</p> Yuli Andriani, Zahidah Hasan, Irfan Zidni, Isni Nurruhwati, Iskandar Iskandar, Rahmadi Kusumoputra Copyright (c) 2021 Jurnal Akuakultur Indonesia https://jma.journal.ipb.ac.id/index.php/jai/article/view/36598 Wed, 21 Jul 2021 10:09:55 +0700 Evaluation of corn steep powder as a protein source for feed of Nile tilapia Oreochromis niloticus https://jma.journal.ipb.ac.id/index.php/jai/article/view/34581 <p>This study was aimed to evaluate the use of corn steep powder (CSP) as a plant protein source in <em>Oreochromis niloticus </em>diet. A commercial feed with 28% protein content and 368 kcal/g energy was used as reference diet, while the test feed consisting of various CSP content, namely 0%, 10%, 20%, and 30% and feed containing soybean meal (SBM) at the level of 20% and 30%. Tilapia were used in the trial with the initial body weight of 6.44 ± 0.29 g, and reared for thirty days in the aquarium at the density of fifteen and fed 3 times daily at a satiation level. All diets were supplied by 0.5% of Cr<sub>2</sub>O<sub>3</sub> as an indicator for digestibility measurement. This study applied the completely randomized design experimental method containing six diet treatments and four replications. The result showed that CSP contains 40.27% protein, 26.10% lactic acid, and minerals. CSP is low in crude fiber and anti-nutritional factors. This study results that increasing the level of CSP significantly decreased feed acidity (P &lt;0.05) compared to the control. The addition of CSP 20% increased feed digestibility including protein, lipid, energy, and dry matter digestibility. CSP 20% treatment increased final body weight, specific growth rate and reduced feed conversion ratio significantly (P&lt;0.05) compare to other treatments. In conclusion, CSP can be used up to 20% to improve the growth performance of tilapia.</p> <p>&nbsp;</p> <p>Keyword: corn steep powder, feed digestibility, growth performance, tilapia</p> <p><strong>&nbsp;</strong></p> <p><strong>ABSTRAK</strong></p> <p>&nbsp;</p> <p>Penelitian ini bertujuan mengevaluasi penggunaan <em>corn steep powder</em> (CSP) sebagai sumber protein nabati pada pakan ikan nila <em>Oreochromis niloticus</em>. Pakan komersial dengan kadar protein 28% dan energi 368 kkal/g digunakan sebagai pakan acuan, sementara pakan uji terdiri atas pakan dengan kandungan CSP sebanyak 0% (CSP0), 10% (CSP10), 20% (CSP20) dan 30% (CSP30) serta pakan dengan kandungan tepung bungkil kedelai (SBM) pada level 20% (SBM20) dan 30% (SBM30) sebagai pembanding. Penambahan Cr<sub>2</sub>O<sub>3</sub> 0,5 % diberikan sebagai indikator untuk mengukur kecernaan. Ikan nila dengan bobot tubuh rata-rata 6.44 ± 0.29 dipelihara dalam akuarium (95×45×45 cm<sup>3</sup>) yang diisi air 100 L dengan kepadatan 15 ekor per akuarium dan diberi pakan tiga kali sehari secara <em>at satiation</em> selama 30 hari masa pemeliharaan. Penelitian ini menggunakan desain rancangan acak lengkap dengan enam perlakuan dan empat ulangan. Hasil penelitian menunjukkan bahwa CSP mengandung protein sebesar 40,27%, asam laktat 26,10%, beberapa mineral dan indeks asam amino esensial 0,90. CSP juga rendah serat kasar dan zat antinutrisi. Peningkatan dosis CSP menurunkan pH pakan secara signifikan (P&lt;0.05) dibandingkan dengan kontrol. Penambahan CSP sampai level 20% meningkatkan nilai kecernaan total, kecernaan bahan, kecernaan protein, kecernaan lemak dan kecernaan energi. Di samping itu, perlakuan CSP 20% meningkatkan bobot akhir, laju pertumbuhan harian dan rasio konversi pakan yang signifikan (P&lt;0,05) dibandingkan perlakuan lainnya. Hasil penelitian ini menunjukkan bahwa pemberian CSP 20% dapat meningkatkan kinerja pertumbuhan ikan nila.</p> <p>&nbsp;</p> <p>Kata kunci: <em>corn steep powder</em>, kecernaan pakan, pertumbuhan, ikan nila</p> Dodi Hermawan, Muhammad Agus Suprayudi, Dedi Jusadi, Alimuddin Alimuddin, Julie Ekasari Copyright (c) 2021 Jurnal Akuakultur Indonesia https://jma.journal.ipb.ac.id/index.php/jai/article/view/34581 Wed, 21 Jul 2021 10:13:04 +0700
