Pembenihan ikan kerapu dihadapkan pada rendahnya sintasan, terutama fase awal hidupnya. Rendahnya sintasan diduga berhubungan dengan belum berkembangnya organ pencernaan larva dan tidak tersedianya pakan yang siap diserap tubuh. Pemberian asam amino bebas seperti taurin dan glutamin melalui rotifer diharapkan dapat meningkatan ketersediaan nutrien yang dapat diserap dengan cepat oleh larva, sehingga sintasan larva tinggi dan dapat tumbuh lebih cepat. Penelitian bertujuan mengukur pengaruh glutamin atau taurin terhadap sintasan dan pertumbuhan larva kerapu bebek Cromileptes altivelis. Larva umur 1 hari (10 ekor.L-1) dipelihara dalam bak fiberglass volume 500 L yang diisi air laut sampai 330 L. Larva diberi pakan rotifer diperkaya 0,5 g glutamin, 0,5 g taurin, atau tanpa glutamin dan taurin. Larva dipelihara selama 16 hari dengan pemberian pakan 2 kali per hari. Satu jam setelah pemberian pakan dilakukan pengamatan terhadap jumlah rotifer dalam saluran pencernaan larva ikan. Hasil penelitian menunjukkan jumlah rotifer dalam saluran pencernaan larva meningkat seiring dengan bertambahnya umur. Namun, jumlah rata-rata rotifer yang dikonsumsi larva pada perlakuan 0,5 g glutamin atau 0,5 g taurin lebih banyak dibanding perlakuan tanpa taurin dan glutamin. Larva yang diberi rotifer hasil pengkayaan dengan 0,5 g glutamin atau 0,5 g taurin memiliki sintasan yang tidak berbeda (P>0,05), masing-masing 19,2±2,25%, dan 24,5±1,20%, dan secara signifikan lebih banyak dibanding larva di perlakuan tanpa glutamin dan taurin yang nilainya 13,0±1,70%. Larva yang diberi rotifer hasil pengkayaan dengan 0,5 g taurin secara signifikan lebih panjang (5,5±0,18 mm) dari ikan di perlakuan 0,5 g glutamin (5,3±0,12 mm). Demikian juga, larva di perlakuan glutamin lebih panjang dari pelakuan tanpa glutamin dan taurin (5,0±0,16 mm). Pengkayaan rotifer menggunakan asam amino bebas taurin atau glutamin dapat meningkatkan sintasan dan pertumbuhan larva kerapu bebek. Namun, taurin lebih baik dibanding glutamin karena memberi efek ke pertumbuhan ikan yang lebih cepat. Kata kunci: taurin, glutamin, kerapu bebek, Cromileptes altivelis. The hatchery production of grouper faced to the problem of low surival rate, especially during the first feeding period. During this period, the digestive organ of larvae was underdeveloped, and the nutrient in live food was not readily absorbed by larvae. Feeding on free amino acids, such as taurine or glutamine, enriched rotifer would be enhanced the nutrient readily absorbed thereby resulting to the improvement of growth and survival rate of larvae. A duplicate experiment was conducted to evaluate the effect of rotifer enriched with free amino acid of glutamine or taurine, on the growth and survival rate of larval grouper Cromileptes altivelis. One day old larvae were cultured in 500 l fiberglass containing 330 l of sea water with a density of 10 ind.L-1. Larvae were fed on rotifer enriched with either 0.5 g glutamine, 0.5 g taurine, or without glutamine nor taurine. Larvae were fed on rotifer twice a day at 08.00 and 14.00, and cultured for 16 days. One h after feeding, rotifer content in the gut of larvae were observed. Results showed that larvae fed on rotifer enriched with 0.5 g taurine or 0.5 g glutamie had higher rotifer content in the gut than that in the other group. Larvae fed on rotifer enriched with 0.5 g glutamine or 0.5 g taurine had the same survival rate (P>0.05), 19.2±2.25% and 24.5±1.20%, respectively; these values were significantly higher than that in the other group which was 13.0±1.70%. The total length of larvae fed on rotifer enriched with 0.5 g taurine (5.5±0.18 mm) significantly was the biggest compared than others; while those fed on rotifer enriched with 0.5 g glutamine (5.3±0.12 mm) was bigger than fish fed on rotifer without glutamine nor taurine (5.0±0.16 mm). Thus, it can be concluded that survival rate and growth of larvae were improved when feeding on rotifer enriched with taurine or glutamine. Nevertheless, taurine was more efective than glutamine due to its effect resulted the highest growth performance of larval grouper. Keywords: taurine, glutamine, grouper, Cromileptes altivelis

Providing high-quality feed is one of the efforts to increase fish productivity and growth and reduce fish mortality. One of the additional alternative feed ingredients as a source of vegetable protein is dragon fruit peel which can be used as an additional ingredient in fish feed. The study of the chemical composition of feed with the addition of dragon fruit peel flour is essential information to determine the effect of addition and the benefits of by-products (waste) from food processing in aquaculture development. This study aims to evaluate the quality of the chemical composition of feed after being treated with the addition of dragon peel flour through proximate analysis. The test was carried out at the Agricultural Product Technology Laboratory of Lampung State Polytechnic, from June to August 2020. The test results showed that dragon fruit peel flour had a carbohydrate content of 50.74%, crude fiber 26.22%, ash 21.35%, protein 5.08%, and fat 4.80% (dry weight). The test results showed that the addition of dragon fruit peel flour increased the protein content in the feed, which increased with the increase in the added dragon fruit flour. The highest protein content in treatment was 1.5%, namely 37.79% (dry weight), and decreased in the addition of dragon fruit flour by 2.0%. The highest ash content in the addition of 2.0% was 11.32% (dry weight). The content of crude fiber, carbohydrates and fat has decreased with the increasing dose of dragon fruit flour. The addition of dragon fruit peel flour can increase the protein content in the feed to substitute in the manufacture of fish feed. This also increases the utilization of dragon fruit peel waste, especially in aquaculture, to reduce waste disposal into the environment.

Permasalahan yang dihadapi oleh mitra Ulam Gading Mas adalah harga pakan yang dari tahun ke tahun meningkat, sehingga meningkatkan biaya produksi. Sementara daya beli masyarakan akan menurun jika harga jual ikan gurame dinaikkan, mengingat kondisi pandemi yang berdampak pada ekonomi. Di sisi lain, pemerintah telah menggalakkan penanaman indigofera di Pringsewu sebagai pakan ternak. Saat ini masyarakat belum mengerti pemanfaatan tanaman tersebut untuk pakan ikan. Diseminasi dan bimbingan teknis aplikasi teknologi hidrolisis tepung daun indigofera sebagai bahan baku pakan perlu dilakukan. Bahan yang mudah didapatkan dan murah, namun dapat meningkatkan pertumbuhan ikan ketika disuplementasikan ke pakan. Pemanfaatan daun indigofera dengan aplikasi teknologi ini berpeluang besar untuk meningkatkan produktivitas budidaya karena dapat meningkatkan pertumbuhan ikan dan harga pakan yang dihasilkan lebih ekonomis. Program pengabdian masyarakat ini meningkatkan pemahaman dan keterampilan pembuatan pakan serta mampu mengapikasikan teknologi hidrolisis enzim selulose pada tepung daun indigofera yang akan disuplementasikan pada pakan ikan gurame. Kata kunci: hidrolisat, tepung daun indigofera, pakan Ikan gurame

Vannamei shrimp (Litopenaeus vannamei) holds significant economic importance in Shrimponesia as a prominent shrimp commodity. The post-larval stage often encounters challenges, primarily due to the shrimp's limited ability to adapt and survive in a new environment. Stocking density is a crucial factor influencing the growth and production performance of vannamei shrimp culture. This study aims to assess the optimal stocking density for achieving optimal growth and survival in L. vannamei. A 40-day maintenance trial was conducted at UD Mina Rahayu Kalianda to investigate the impact of different stocking densities on water quality in the maintenance media. The study utilized containers with varying stocking densities: treatment A (1 shrimp/L), treatment B (1.5 shrimp/L), and treatment C (2 shrimp/L), each with three replications. The findings revealed survival rates (SR) of 83.33% for treatment A, 62.78% for treatment B, and 58.33% for treatment C. Mean Body Weight (MBW) values were recorded as 1.2592 g/shrimp for treatment A, 1.1216 g/shrimp for treatment B, and 0.7728 g/shrimp for treatment C. Average Daily Growth (ADG) results showed 0.0313 g/shrimp for treatment A, 0.0279 g/shrimp for treatment B, and 0.0192 g/shrimp for treatment C. Based on the study, the recommended stocking density for white vannamei shrimp is 40 shrimp/L, demonstrating improved growth and survival rates for this species.
