Abstract

Bullet tuna (Auxis rochei Risso 1810) as an export commodity, have a positive impact on Indonesia's foreign exchange. Utilization status is fully exploited, and captured gonad immature. The aim of this study is to estimate the utilization, growth, and population of bullet tuna. Conducted in Labangka (Sumbawa Regency) during May-August 2019. The compilation of the fork length frequency data (FL) of bullet tuna uses sampling, observation, dialogue and documentation techniques. Alleged utilization level of bullet tuna resources is calculated using a surplus production model. Growth parameters (K and L?) were estimated by the Electronic Length Frequency Analysis (ELEFAN I) method on the Scanning of K-values FAO-ICLARM Stock Assessment Tools II (FiSAT II). FiSAT II software is also used for population estimation based on FL frequency data. Tuna fishing in Labangka uses surface longlines and outboard motorboats. The status of the utilization of bullet tuna in the waters of southern Sumbawa reaches fully exploited and low growth rates. Bullet tuna fisheries activities in Labangka are small scale fisheries that apply the rules of responsible fisheries. So that management is sustainable, it can be done by increasing the size of the fishing line, beginning with the socialization to fishermen.

Abstract

Penggunaan teknologi dalam proses pembangunan pertanian (termasuk perikanan), merupakan salah satu syarat mutlak dalam pembangunan dalam  bidang tersebut. Penelitian ini bertujuan untuk mengetahui, mendskripsikan, dan mengkaji variabel-variabel yang mempengaruhi produksi budidaya udang vaname di Desa Kidang, dan menganalisis kelayakan usaha (keuntungan dan kerugian) kegiatan budidaya udang vaname di Desa Kidang. Penelitian ini dilakukan di Desa Kidang Lombok Tengah pada bulan Juli hingga Agustus 2018. Metode yang digunakan dalam penelitian ini adalah metode survey deskriptif, dan pengumpulan data menggunakan metode sensus yang meliputi kegiatan inventarisasi dan identifikasi potensi dan permasalahan di lokasi penelitian. Analisis data menggunakan Regresi- Korelasi yang bertujuan untuk memperediksi determinasi/pengaruh variabel bebas (X) tehadap variabel terkait (Y).  Hasil evaluasi  teknis budidaya udang di desa kidang sebesar 4.380 kg/Ha/MT dan ukuran/size udang panen 79 individu/kg dan rerata berat tubuh (averange body weight/ABW) 12,7 gram/individu,serta sintasan mencapai 98%, dan  FCR 1,43. Hasil analisis kelayakan usaha menunjukkan nilai Benefit-Cost Ratio (B/C Ratio) = 2,13. Dapat disimpulkan bahwa teknologi budidaya udang vaname yang diterapkan oleh pembudidaya udang vaname di desa kidang lombok tengah memiliki efektifitas yang sangat tinggi (SR, Zize), dan evesiensi yang sangat baik (B/C Ratio), dan produktivitas tambak yang sangat tinggi.

Abstract

Selama lebih dari tiga dekade, masyarakat pesisir telah mengelola dan memanfaatkan lahan pesisir Pulau Sumbawa untuk budidaya bandeng (Chanos chanos). Mereka memanfaatkan pasang surut dan topografi daratan pesisir untuk melakukan kegiatan di tambak. Bandeng dipilih karena: kegemaran masyarakat, organisme euryhaline, teknologi budidaya bandeng tergolong sederhana, biaya produksi rendah, dan sintasan tinggi. Tujuan penelitian untuk mengetahui status keberlanjutan pengelolaan dimensi bioekologi, teknologi, dan ekonomi serta mengetahui atribut-atribut sensitif dari masing-masing dimensi. Keberlanjutan merupakan amanat dalam pengelolaan perikanan dunia dan Indonesia. Penelitian ini dilakukan di tiga kabupaten (Sumbawa, Dompu, Bima) selama Juni - Oktober 2018. Penghimpunan data menerapkan metode survey dependen dengan teknik sampling, dialog, observasi, dan dokumentasi. Pengolahan data menerapkan berbagai persamaan statistik dan non statistik. Analisis keberlanjutan menggunakan teknik penilaian untuk akuabisnis bandeng (Rapmilkfish). Hasil Analisis Rapmilkfish menunjukkan status keberlanjutan dimensi bioekologi 'Berkelanjutan', dimensi teknologi 'Cukup Berkelanjutan', dimensi ekonomi 'Kurang Berkelanjutan', dan atribut sensitif sebanyak 12 atribut. Dapat disimpulkan bahwa tingkat penerapan teknologi budidaya bandeng tergolong ramah lingkungan dan berkorelasi positif dengan kelestarian sumber daya alam. Sehingga, kegiatan budidaya bandeng dapat dilanjutkan tanpa harus menaikkan taraf teknologi budidaya bandeng dalam upaya meningkatkan produktivitas tambak.

Abstract

The potential of fisheries resources in the Indonesian sea consists of four fishery resources, namely: large pelagic (451,830 tons per year) and small pelagic (2,423,000 tons per year), demersal fisheries resources (3,163,630 tons per year), shrimp (100,720 tons per year) per tofu) and reef fish (80,082 tons per year). This study aims to determine the catch using demersal trolling in the Sape Strait and to determine the biological status of fish caught by using a troll demersa fishing rod To determine the biological status of fish caught using demersal trolling rods. This research will be carried out in the waters of the Sape Strait of West Nusa Tenggara. Data collection methods used in this study are descriptive, quantitative and qualitative methods. These methods describe in detail all the activities carried out during the research activities, so that they are able to answer the problems or goals that have been set. The results of this study were processed using Fisheries Biology Analysis such as length and weight relationship pattern analysis, growth pattern analysis of the condition of the feasibility of the fishing gear analysis of fishing gear productivity effectiveness of fishing gear environmental friendliness analysis of the gear sensitivity of the fishing gear business feasibility analysis

Abstract

Milkfish cultivation with traditional technology in Mertak Village only lasts one cycle per year. The limited cycle of milkfish cultivation causes it to be less desirable, even though the profit level is quite high. For this reason, this study aims to study the key variables of cultivation and estimate the feasibility of the milkfish cultivation business. This research was conducted in Mertak Village, Central Lombok. used in this research is descriptive survey, and data collection using census method. Data analysis uses Regression-Correlation which aims to predict the determination / influence of the independent variable (X) on the dependent variable (Y). The results of the technical evaluation of milkfish cultivation in the village of Mertak amounted to 563 kg/ha/cycle with the size of the milkfish harvesting 8 individuals/kg. In addition, averange body weight (ABW) of 125 grams/individual was obtained, survival rate (SR) reached 53.68%, and FCR 0.23. The results of the business feasibility analysis show the value of the Benefit-Cost Ratio (B/C Ratio) = 2.218, which means that the milkfish cultivation business is feasible to continue because the B/C ratio is >1.0. The milkfish cultivation activities in Mertak Village, Pujut Subdistrict, Central Lombok Regency have followed the rules of good aquaculture practice (GAP). The milkfish farmers consistently run their business to increase pond productivity.
