The research method used was an experimental method, with a non-factorial completely randomized design (CRD). Each treatment (5000, 7500, and 10000 shrimp/pond) was repeated 3 (three) times. The observations showed that the growth of absolute weight and length of the 5000 shrimp/pondtreatment gave the best results, 8.82 g (0.13 g / day) and 8.81 cm (0.126 cm / day). However, the analysis of variance indicate that the stocking density of L.vannamei in the range of 5,000 to 10,000 has no significant effect on differences in growth, both weight or length. Stocking density of L.vannamei was detected to give a significant on survival rate. One-way analysis of variance and the Least Significant Difference (LSD) test showed that the stocking density of 5,000 was significantly in their survival on the 7,500 and 10,...

Sektor perikanan memiliki potensi untuk terus dikembangkan dalam rangka mewujudkan ketahanan pangan dan sebagai sumber protein yang sangat dibutuhkan oleh manusia. Kelompok Budidaya Ikan Susukan Lestari di bawah binaan Desa Tambong, telah berhasil melahirkan suatu terobosan untuk memberikan nilai tambah bagi desa dengan menghadirkan lokasi wisata edukasi yang bergerak dibidang perikanan dan pertanian. Namun, kualitas air yang digunakan masih sangat rendah, khususnya tingkat kekeruhan yang menjadi permasalahan dalam perkembangan usaha ini. Pada kegiatan ini dilakukan pendampingan untuk penerapan water treatment atau pengolahan air sebelum dialirkan ke kolam budidaya. Kegiatan ini dilaksanakan di Lokasi Wisata Edukasi Perikanan dan Pertanian Desa Tambong, Kecamatan Kabat, Kabupaten Banyuwangi.

Dusun Telong-elong adalah salah satu situs lokasi pengembangan kegiatan budidaya lobster. Pakan yang digunakan pembudidaya beragam dan diperoleh dengan mudah karena pasokannya melimpah dengan harga terjangkau jika dibanding pakan pellet komersil. Hal tersebut berdampak terhadap kualitas lobster yang dihsailkan. Kegiatan pengabdian masyarakat dan penelitian ini bertujuan untuk mengetahui kandungan protein pada lobster pasir (P. homarus) yang dibudidayakan serta pengaruh pemberian jenis pakan terhadap pertumbuhan. Metode pendekatan yang dilakukan adalah deskriptif dengan metode pengumpulan data wawancara, observasi dan pengujian. Lobster pasir diberi pakan berbeda yaitu rucah segar, rucah asin dan bekicot, pengumpulan data dilakukan 3 kali setiap rentang waktu 2 minggu. Hasil penelitian menunjukkan lobster pasir yang diberi pakan rucah segar memiliki kandungan protein tertinggi (27,10 %), ...

Penelitian ini bertujuan untuk mengetahui evektivitas ekstrak meniran serta dosis terbaik sebagai penghambat serangan jamur Saprolegnia sp. pada telur ikan lele Mandalika. Metode penelitian yang digunakan yaitu metode eksperimental dengan Rancangan Acak Lengkap (RAL) yang terdiri dari 5 perlakuan dan 3 kali ulangan. Perlakuan konsentrasi ekstrak meniran yang diberikan meliputi 0 ppm, 1000 ppm, 2000 ppm, 3000 ppm, dan 4000 ppm. Parameter uji yang diamati adalah daya tetas telur (HR), sintasan (SR), dan kualitas air. Hasil penelitian menunjukkan perendaman telur dalam ekstrak meniran memberikan pengaruh yang sangat nyata terhadap daya tetas dan sintasan ikan lele mandalika, dimana pada konsentrasi 3000 ppm memiliki potensi yang sangat baik untuk memproteksi t...

The attractiveness of koi fish can be measured by its brilliant color and health or stamina. The brightness of color in ornamental fish can be improved by providing feed containing carotenoids. Carrots (Daucus carrota), pumpkin (Cucurbita moschata), sweet potatoes (Ipomoea batatas) and gumitir flowers (Tagetes spp.) Are some natural carotenoid sources that are thought to increase the brightness of ornamental fish. The purpose of this study was to determine the effect of the addition of natural pigments in feed on the brightness and growth of koi (C. carpio) seeds. This study used a Completely Randomized Design (CRD) with an experimental method of 5 treatments (P1, P2, P3, P4, P5) and 3 replications. P1 = ordinary pellet feed, P2 = addition of carrot flour, P3 = addition of pumpkin flour, P4 = addition of sweet potato flour, P5 = addition of gumitir flour. The results showed that pumpkin flo...

Penelitian ini dilakukan untuk mengetahui dan mendeskripsikan jenis - jenis patogen penyebab penyakit ikan mas di Kabupaten Lombok Timur. Proses identifikasi dimulai dengan mengkultur bakteri dari organ ikan mas yang terinfeksi yaituginjal dan cairan abdomen. Bakteri yang didapat diidentifikasi secara morfologi dan biokimia kemudian di cocokkan dengan buku panduan Bergey's Manual of Determinative Bacteriology. Hasil pencocokan tersebut menujukkan bahwa jenis bakteri yang terdapat pada organ ginjal dan cairan abdomen ikan mas yang terserang penyakit di BBI Aikmel adalah Edwarsiella tarda dan yersinia sp.

The etiological agent of this disease was a virulent strain of Vibrio parahaemolyticus. However, a technology to treat or to prevent the disease infection has not been established yet, and probiont could be a potential approach for this disease. Thus, this study aimed at screening 35 lactic acid bacteria (LAB) that originated from the gastrointestinal tract of wild white shrimp for the production of antivibrio compounds using an agar well diffusion. The result showed that three LAB strains (LAB-1, LAB-2, and LAB-3) showed antivibrio activity indicated by the formation of clearance zone (diameter of >10mm) on the diffusion agar plate. When the extracellular products (ECP) were incubated with proteinase K, the antivibrio activity was disappeared which indicated that the antimicrobial compounds were bacteriocin-like inhibitory substa...

Politeknik Negeri Banyuwangi is participating through empowerment in a small livestock production business. Jaya Sentosa Farm was chosen as a partner, which focuses on fattening sheep. The problem faced by a partner is the lack of knowledge related to feeding management. The program is carried out by intensively assisting them in feeding management so that in the future they can independently develop the skills they have acquired. The feed ingredients used come from Banyuwangi's local resources. The feed ingredients are corn husk, coffee husk, rice bran, and molasses. Based on the results of the program, an optimal and economical feed formula was obtained at a price of IDR 2,334/kg. Feed mixing uses a double ribbon mixer so that an even mixture is obtained in a short time (decreased by 50%) ==== Guna turut menyukseskan program pemerintah Republik ...
