Abstract

Kebutuhan benih ikan bandeng berkualitas meningkat pesat di Indoensia, namun ketersediaannya terbatas dan tidak mencukupi kebutuhan. Untuk mengatasi permasalahan tersebut, maka perlu dilakukan perbaikan melalui teknologi budidaya dalam usaha pembenihan untuk menjamin kesinambungan dan kualitas nener bandeng. Pengamatan ini dilaksanakan di PT Esaputlii Prakarsa Utama (PT EPU) pada tanggal 4 Maret sampai dengan 31 Mei 2019. Tujuan pengamatan adalah mengevaluasi aspek teknis dan performansi kinerja produksi nener bandeng. Metode observasi dan wawancara digunakan untuk mengumpulkan data primer maupun sekunder. Aspek teknis dan performansi kinerja produksi nener bandeng di PT EPU sudah baik dan sesuai standar yang berlaku yaitu rata-rata produktivitas 16.410.357 ekor/bulan, FR 93,26%, HR 89,25%, dan SR 56,97%.

Abstract

Kappapicus alvarezii is an important economic commodity of seaweed to be developed in Indonesia. In the context of its development, seeds from tissue culture are needed.The aim of this research is to examine the growth of seaweed by immersing NPK, TSP and combination fertilizers between NPK + TSP on absolute weight, Specific Growth Rate (SGR) and morphological growth including talus length and seaweed talus diameter. This research was conducted from March 2 to May 15, 2020 in the waters of Sumberkencono Village, Wongsorejo Sub-District, Banyuwangi District, East Java. This study uses Kappaphycus alvarezii seaweed seedlings from tissue culture results from the Situbondo Brackish Aquaculture Fisheries Center, and uses treatment fertilizers, namely NPK fertilizer with 15% Nitrogen (N) composition, Phosphate (P2O5) 15%, and Potassium (K) 15% at a dose of 2 g / l and TSP fertilizer with an element composition of Phosphate (P2O5) 18% at a dose of 2 g / l, as well as a combination of NPK fertilizer 1 g / l and TSP 1g / l soaked for 15 minutes and control or without soaking. From the results of the research, obtained weight growth of seaweed by immersing NPK + TSP obtained good growth (Absolute Weight 57.48 grams, SGR 7.21%, talus length 8.5 cm, diameter 6.52 mm), then NPK treatment (Weight Absolute 37.80 grams, SGR 6.13%, Talus length 8.1 cm, diameter 6.43 mm), TSP treatment (Absolute Weight 31.6 grams, SGR 5.69%, Talus length 7.9 cm, diameter 6.36 mm) followed by control (Absolute Weight 24.8 grams, SGR 5.10%, Talus length 7.6 cm, diameter 6.32 mm).

Abstract

Lele sangkuriang (Clarias gariepinus) merupakan varietas ikan lele unggul dan bernilai ekonomi tinggi. Pakan awal yang baik bagi larva ikan lele sangkuriang adalah pakan alami, seperti cacing sutra. Saat ini penyediaan cacing sutra masih banyak mengandalkan dari alam. Penelitian ini bertujuan menganalisis kandungan nutrisi, kandungan bakteri dan kinerja pakan alami cacing sutra dari tiga sumber berbeda merujuk pada pertumbuhan dan kelangsungan hidup larva ikan lele sangkuriang (Clarias gariepinus). Metode yang digunakan adalah eksperimen dengan Rancangan Acak Lengkap (RAL) dengan variabel uji berupa sumber pakan yang berbeda, di antaranya perlakuan A (cacing sutra hasil pemeliharaan pada media campuran ampas tahu 80%, dedak padi 10%, dan tepung ikan 10%), perlakuan B (cacing sutra hasil budidaya petani) dan perlakuan C (cacing sutra hasil tangkapan dari alam). Hasil penelitian kandungan nutrisi masing-masing perlakuan kandungan protein tertinggi terdapat pada perlakuan C sebesar 11,10%, kemudian perlakuan A sebesar 10,98%, dan terkecil pada perlakuan B yaitu sebesar10,23%. Hasil uji kandungan bakteri cacing sutra pada perlakuan A tidak mengandung bakteri Salmonella sp. maupun bakteri Escherichia coli, pada perlakuan B dan perlakuan C positif mengandung bakteri Escherichia coli. Perlakuan A memberikan tingkat efektivitas terbaik terhadap SR yaitu sebesar 87±0,007c %, pertumbuhan panjang mutlak sebesar 40,07±1,87c mm, berat mutlak sebesar 0,4701±0,0836 g dan rasio konversi pakan sebesar 3,740±0,6189 g. Hasil uji ANOVA menunjukkan perlakuan yang diberikan berpengaruh signifikan (P0,05) terhadap pertumbuhan berat mutlak, SGR, dan rasio konversi pakan.

Abstract

Introduction To meet the natural food for fish cultivators, community assistance was held in the village of Way Gelang, Tanggamus, Lampung. about hygienic and sustainable cultivation of silk worms. Increasing income to become a fisherman whose income is uncertain. This village has formed a business group for growing tilapia and catfish cultivation under the auspices of SUPM Kotaagung, to meet the needs for catfish and tilapia seeds they still buy from outside at quite high prices. As well as the high price, with training to the community about hygienic and sustainable silk worm cultivation, it is hoped that the community can cultivate silk worms for fish hatchery for their own consumption and can be sold to hatchery farmers so they can reduce operational costs and get additional income from the sale of silk worms. Objective of the activity: to assist fish farmers in cultivating silkworms hygienically and sustainably. Methods of activities for establishing cultivation groups, outreach, training, mentoring from pre-production to production. The results of community activities are able to cultivate silkworms well. The conclusion of the mentoring activities was very well received by the hatchery farming community in Way Gelang Lampung Village by providing direct techniques on silkworm cultivation.

Abstract

Vibrio parahaemolyticus is a gram-negative halophilic bacterium that lives in estuaries and beaches. These bacteria are agents that cause septicemia in shrimp during the larval and post larvae period. This study aims of this experiment is to determine the effect of mangrove leaf, root, stem and fruit extracts of Rhizophora stylosa growth of the V. parahaemolyticus bacteria. The experimental design used a completely randomized design (CRD) with positive control treatment (Papper disk containing chloramphenicol); Negative control (Papper disk containing methanol) P1 = mangrove extract 100 mg/L; P2 = 200 mg/L mangrove extract; P3 = 400 mg/L mangrove extract and in doing it on 3 times. The research parameter was measuring the bacterial inhibition zone. The results showed that the mangrove leaf, root, stem and fruit extracts of R. stylosa significantly affected on the inhibition zone and of high concentrations of the leaf, root, stem extract concentrations of R. stylosa mangrove fruit, the wider the bacterial inhibition zone. The concentration of 400 mg/L extracts of leaves, roots, stems and fruit heads of R. stylosa mangroves was the most effective concentration to inhibit the growth of V. parahaemolyticus bacteria, which showed an average root inhibition zone of 9.5 mm, leaves 7.7 mm, stems 6.5 mm, and fruit heads 4.8 mm.
