 ABSTRAK Manajemen pemberian pakan merupakan faktor utama yang paling penting untuk menciptakan keberhasilan dalam suatu budidaya perikanan. Tujuan penelian ini adalah; (1) mengetahui tentang manajemen pemberian pakan pada pembesaran ikan lele mutiara di karamba tancap (FR, FCR, dan SR). (2) Mengetahui tentang kualitas air (suhu, DO, pH, dan kecerahan). Metode penelitian yaitu melakukan pemberian pakan, penimbangan sampel dan pengecekan kualitas air (pH, suhu, DO, dan kecerahan). Perlakuan pemberian pakan, dan pengecekan kualitas air dilakukan selama 22 hari, dan penimbangan sampel dilakukan selama 2 minggu sekali untuk menentukan FR. Hasil FR pada minggu pertama 960 g, dan minggu kedua 1.432 g. Nilai FCR selama kurang lebih 22 hari dengan FR 3% mencapai sebesar 1,05 dengan jumlah pakan yang dihabiskan mencapai 33 kg, nilai SR 99%. Hasil analisa kualitas air yaitu nilai rata-rata suhu pada pagi hari 29,3oC dan pada sore hari 29,4oC, nilai rata-rata DO pada pagi hari 8 ppm dan pada sore hari 8,2 ppm, nilai rata-rata pH pada pagi dan sore hari 8,1, kecerahan mendapatkan hasil 39 cm. Hasil analisa kualitas air pada karamba tancap pembesaran ikan lele mutiara memenuhi persyaratan SNI 7550 : 2009.Kata kunci: Manajemen pakan (FR, FCR, SR) dan kualitas air (DO, pH, suhu, kecerahan)ABSTRACTFeeding management is the most important main factor to create success in a aquaculture.

Abstract

ABSTRAKIkan Cupang (Betta splendens) merupakan salah satu jenis ikan hias yang digemari di Indonesia. Peminat ikan ini bertambah seiring perkembangan teknologi dan pemasaran, baik secara online maupun offline. Pemilihan pakan yang kurang tepat menyebabkan pertumbuhan ikan yang tidak sesuai dengan usia ikan. Salah satu alternatif makanan yang biasa dipakai adalah pakan alami berupa jentik nyamuk dan cacing sutra. Penelitian ini mengkaji efektifitas pakan alami tersebut terhadap pertumbuhan ikan Cupang. Penelitian menggunakan Rancangan Acak Lengkap, dengan 4 perlakuan, dan setiap perlakuan memiliki 6 ulangan. Sampel tiap perlakuan adalah 1 ekor ikan Cupang betina usia 2 bulan. Pemeliharaan selama 4 minggu, dengan pengukuran biomassa ikan setiap minggu. Parameter Kualitas air meliputi pH, suhu dan oksigen terlarut (DO). Perbedaan jenis pakan alami tidak memberikan pengaruh yang berbeda pada pertumbuhan ikan Cupang Pertumbuhan biomassa ikan Cupang dengan pakan A (100% cacing sutra) 10,2 gr, B (100%  dan D (25% cacing sutra dan 75 jentik nyamuk) sebesar 2,8 gr.  Pengukuran kualitas air selama penelitian di dapatkan pH air pada kisaran 7,2 – 7,6, sementara suhu pada 26,5 - 27,0 oC dan DO 4,2-4,8 ppm.Kata kunci: pakan alami, ikan cupang, pertumbuhan biomassa, kualitas air, perbedaan dosis ABSTRACTBetta fish (Betta splendens) is one of ornamental fishes, which are popular in Indonesia. Its enthusiasts increase because of the development of technology and marketing, both online and offline. Selections of improper food cause the fish to grow slower than its size according to the age. One commonly used alternative food is natural food such as mosquito larvae and silk worms. This study examines the effectiveness of the natural food on the growth of Betta fish. This research used a completely randomized design, with four treatments, and each treatment had six replications. Samples of each treatment were two month-old female Betta fish. The fish were treated for 4 weeks, with fish biomass measured each week. Additional parameters were pH, temperature and dissolved oxygen (DO). The different types of natural food had no different effect on the growth of Betta fish. Biomass growth of Betta fish fed with A (100% silk worms) 10.2 g, B (100% mosquito larvae) 7.8 g, C (50% silk worms and 50 % mosquito larvae) 5.8 g, and D (25% silk worms and 75 %larvae mosquitoes) of 2.8 g. pH water was in range of 7,2 – 7,6, while the temperature was at 26,5 - 27,0 oC and DO 4,2-4,8  ppm.Keywords:  natural feeds, betta fish, absolute weight growth, quality water,

Abstract

ABSTRAKBulu babi adalah kelompok hewan tidak bertulang belakang Avertebrata yang termasuk dalam filum Echinodermata.  Hewan ini banyak ditemukan  pada perairan  dangkal dan biasanya terdapat  pada padang lamun dan daerah  terumbu karang.  Di seluruh dunia, terdapat kurang lebih 800 jenis bulu babi dari kelas Echinodea   yang   terbagi dalam dua subkelas yaitu Perischoechinoidea dan Echinoidea. Oi Indonesia sendiri, terdapat  kurang  lebih  84 jenis  bulu babi  yang berasal  dari  31 suku dan 48  marga. Perairan pulau  Gill  Raja  Panjang memiliki beberapa  biota echinodermata salah satunya bulu babi. Bulu babi tersebar di ekosistem padang lamun dan terumbu karang. Keberadaan bulu babi berpengaruh pada  terumbu  karang,  karena dapat  mejadi  kontrol  bagi perkembangan mikroalga  dan  meningkatnya bulu babi akan  berdampak   negatif bagi ekosistem lamun. Bulu babi yang di dapatkan yaitu Diedema setosum, Sa/macis belli, Mespi/ia g/obu/us, Echinometra mathaei. Kelimpahan bulu babi di Pulau Gill Raja berkisar antara 3-4.33 ind/m2,  dengan kelimpahan tertinggi terdapat di Stasiun II 4.33 ind/m2 dan terendah di stasiun I yaitu sebesar 3 ind/m2. Keanekaragaman bulu babi di Pulau Gili Raja tergolong dalam keanekaragaman rendah  dengan nilai sebesar 0,415, keseragaman tergolong keseragaman rendah sampai tinggi mempunyai nilai sebesar 0,743 sempai 0,498, dan dominansi tergolong  dalam dominansi sedang dengan  nitai sebesar 0,712.Kata Kunci  : Bulu Babi,  line transect,  dan Statified random  sampling.ABSTRACTSea urchins are a group of invertebrate animals belonging to the phylum Echinoderms. These animals are mostly found in shallow waters and are usually found in seagrass beds and coral reef areas. Worldwide, there are approximately 800 species of sea urchins from the Echinodea class which is divided into two subclasses, Perischoechinoidea and Echinoidea. Oi Indonesia itself, there are approximately 84 types of sea urchins originating from 31 tribes and 48 genera. The waters of the Gill Raja Panjang island have several echinoderms, one of which is sea urchins. Sea urchins are scattered in seagrass and coral reef ecosystems. The presence of sea urchins has an effect on coral reefs, because it can be a control for microalgae development and the increase in sea urchins will have a negative impact on seagrass ecosystems. The sea urchins that were obtained were Diedema setosum, Sa/macis belli, Mespi/ia g/obu/us, Echinometra mathaei. The abundance of sea urchins on Gill Raja Island ranged from 3-4.33 ind/m2, with the highest abundance at Station II 4.33 ind/m2 and the lowest at station I at 3 ind/m2. The diversity of sea urchins on Gili Raja Island is classified as low diversity with a value of 0.415, uniformity belonging to low to high uniformity has a value of 0.743 to 0.498, and dominance is classified as moderate dominance with a value of 0.712.Keywords : Sea urchins, line transect,  dan Statified random  sampling

ABSTRAKPenelitian ini bertujuan untuk mengetahui karakteristik mutu burger ikan nila (Oreochromis niloticus) dengan  formulasi terbaik selama masa simpan suhu dingin (50C). Penelitian ini diawali dengan penelitian pendahuluan untuk mengetahui formulasi terbaik dari burger ikan nila dan dilanjutkan dengan penelitian utama yaitu untuk mengetahui karakteristik mutu burger ikan nila dengan formulasi terbaik selama masa simpan suhu dingin (50C). Parameter analisis yang diamati pada penelitian pendahuluan adalah analisis proksimat (kadar air, kadar protein, kadar kadar lemak, kadar abu), sedangkan pada penelitian utama adalah organoleptik (kenampakan, aroma, rasa dan tekstur), uji mikrobiologi (Angka Lempeng Total), uji aw. Hasil penilaian komposisi proksimat menunjukkan bahwa formulasi terbaik burger ikan nila  (Oreochromis niloticus) adalah formulasi F2. Selama penyimpanan pada suhu dingin (50C) burger ikan nila (Oreochromis niloticus) dengan formulasi terbaik (F2) memiliki daya tahan selama 7 hari dengan nilai alt 2,4x104koloni/gram dan aw 0,60.Kata Kunci: burger ikan nila, uji organoleptik, uji ALT, uji aW, masa simpanABSTRACTThis research aims to determine the characteristics of tilapia burger (Oreochromis niloticus) with the best formulation during cold storage (50C).
