Abstract

Keseimbangan energy-protein memeiliki peran penting dalam memenuhi kebutuhan nutrisi ikan dan meningkatkan performa pertumbuhan ikan. Limbah kulit ari kelapa memiliki potensi sebagai sumber lemak yang dapat digunakan sebagai suplemen pakan ikan. Penelitian ini mengevaluasi pengaruh minyak kulit ari kelapa terhadap laju pertumbuhan spesifik (SGR) dan tingkat kelangsungan hidup (SR) ikan nila (Oreochromis niloticus). Empat pakan dengan tingkat sumber lemak yang berbeda yang diformulasikan dengan menambahkan minyak kulit ari kelapa pada pakan ikan komersial pada level 0%, 2%, 4%, dan 6% selama 35 hari. Laju pertumbuhan spesifik (SGR) tertinggi yang diamati pada ikan didapatkan pada ikan yang diberi minyak kelapa pada tingkat 2% dan 4% dibandingkan perlakuan yang lainnya (P 0,05). Hasil penelitian menunjukkan bahwa minyak kelapa sebanyak 2% merupakan level yang direkomendasikan sebagai suplemen pada pakan ikan nila yang ditunjukan dengan laju pertumbuhan spesifik yang baik.

Abstract

Tujuan penelitian ini adalah untuk mengetahui proses budidaya sistem bioflok melalui penghitungan FCR dan parameter pertumbuhan ikan lele di perairan pH rendah. Sistem budidaya ikan di bioflok telah dikenal bermanfaat bagi budidaya ikan. Apabila dalam sistem budidaya padat tebar terlalu tinggi maka dapat dihasilkan limbah (ammonia) yang tinggi pula. Selain itu, padat tebar yang tinggi juga dapat menghabiskan pakan sekitar 70% dari biaya operasional dan mempengaruhi nilai FCR (Feed Convertion Ratio). Untuk meminimalisasi kondisi tersebut dilakukan salah satu inovasi yaitu budidaya sistem bioflok. Sistem ini mampu untuk memperbaiki kualitas air dan mengurangi biaya pengeluaran pemberian pakan serta menurunkan nilai FCR (Feed Convertion Ratio). Kondisi balita stunting di Indonesia masih tinggi yaitu mencapai 30,8% yang disebabkan kekurangan protein dan kalsium. Daging ikan lele dipercaya mampu mengatasi permasalahan tersebut. Agar balita di Indonesia mendapat pemenuhan gizi untuk mengurangi stunting maka pembudidaya harus mampu memproduksi ikan lele yang tinggi. Telah dilakukan pengamatan terhadap perkembangan bobot ikan selama bulan Oktober 2023 – Desember 2023 pada kolam pH rendah berbasis bioflok di Desa Apung, Kabupaten Bulungan. Parameter yang diamati pada penelitian ini meliputi, pertumbuhan bobot mutlak, rasio konversi pakan, dan kelulushidupan, pada kondisi pH rendah (4 – 6) menggunakan budidaya sistem bioflok. Hasil pengamatan menunjukkan nilai pertumbuhan bobot mutlak tertinggi 32 gram dan terendah 3 gram, nilai Feed Convertion Ratio (FCR) atau rasio konversi pakan sebesar 0,8 Survival Rate (SR) atau kelulushidupan sebesar 96,2%.

Abstract

Carrageenan is a polysaccharide extracted from the seaweed, Kappaphycus alvarezii. Carrageenan serves as a food additive, functioning as both a stabilizer and a gelling agent in vanamei shrimp otak-otak (a type of Indonesian fish cake). This study aimed to determine the effect of different carrageenan concentrations on the sensory acceptance and chemical characteristics of the vannamei shrimp otak-otak. The study was conducted using an experimental method with five treatments: carrageenan addition of 0% (A), 0,5% (B), 1% (C), 1,5% (D), and 2% (E). Preference was assessed using a hedonic test covering appearance, aroma, texture, and taste, as well as a chemical test measuring moisture, ash, fat, protein, carbohydrate, and crude fiber content. Based on the analysis of 20 semi-trained panelists, the most preferred treatment was the addition of 1% carrageenan, with average scores of 7.4 (liked) for appearance, 7.1 (liked) for aroma, 7.5 (liked) for texture, and 7.3 (liked) for taste. Chemical analysis showed 54.66% moisture, 2.34% ash, 8.08% protein, 0.01% fat, 34.91% carbohydrate, and 2.72% crude fiber. The addition of 1% carrageenan was identified as the most favorable concentration compared with the other treatments.
