Abstract

Rajungan merupakan komoditi perikanan dengan nilai jual cukup tinggi, namun nelayan di Teluk Santong sampai saat ini masih kesulitan dalam menentukan daerah penangkapan rajungan. Oleh karena itu diperlukan informasi mengenai daerah penangkapan rajungan yang potensial. Tujuan penelitian ini adalah untuk memetakan zona potensi penangkapan rajungan berbasis satelit Aqua Modis dan menganalisa keterkaitan SPL dan klorofil-a terhadap sebaran zona potensi penangkapan rajungan. Metode yang digunakan adalah metode pengindraan jauh dengan interpretasi digital untuk memperoleh data sebaran zona potensi penangkapan rajungan. Survei lapangan dilakukan dengan cara pengambilan titik sampel untuk uji akurasi hasil interpretasi. Suhu permukaan laut dan klorofil-a diperoleh dengan mengunduh citra satelit Aqua Modis. Analisis yang digunakan dalam penelitian ini adalah analisis regresi linear yang berfungsi untuk melihat pengaruh suhu permukaan laut dan klorofil-a terhadap hasil tangkapan rajungan. Hasil yang diperoleh adalah sebaran SPL berkisar antara 28,9⁰C sampai 31,6⁰C dengan nilai rata-rata 30,22⁰C, Sedangkan klorofil-a berkisar antara 0,27mg/m3 sampai 2,34mg/m3dengan nilai rata-rata 0,83mg/m3. Hasil tangkapan rajungan selama enam bulan yaitu sebanyak 454,8 kg, hasil tangkapan tertinggi di temukan pada bulan Desember dan hasil tangkapan paling rendah di bulan Februari. Nilai akurasi yang diperoleh mencapai 82% sehingga hasil interpretasi citra satelit layak diterima.

Abstract

Bali Sardinella (Sardinella lemuru) is one of the small pelagic fish widely utilized by people in Lombok island. It serves not only to meet food needs on a household scale but also as a raw material on an industrial scale. This causes a high level of utilization of the Bali Sardinella in West Nusa Tenggara (WNT) Province. Awang Bay is one of the fishing ground centers in the province. This study aimed to determine and describe the population condition and sustainability status of the Bali Sardinella fishery in the Awang Bay based on the biological fisheries condition. The sampling was carried out in Awang Bay from July to August 2022. A total of 306 individuals of fish were sampled and measured for length and weight. This study found that the fish population had a negative allometric growth pattern, indicating a thin body shape. The population was dominated by young fish with 6,40-16,20 cm fork length and 3,0-39,0 g weight. The proportion of fish population that are suitable for maturation, catching, and consumption was 30%, 30%, and 37%, respectively. Feasibility parameter values ranging below 50% indicated that Bali Sardinella fishery activities from July until August were less sustainable. The results of this study can be used as one of the basic information for the local government in developing fisheries management policies in the WNT Province.

Abstract

Tujuan kegiatan pendampingan ini untuk melatih siswa agar mampu menyelesaikan soal dengan cepat dan tepat serta menemukan trik cara mudah menyelesaikan soal untuk menghadapi olimpiade sains cabang geografi tingkat Kabupaten/ Kota. Tahap awal pelaksanaan pendampingan kompetisi sains nasional dilakukan seleksi siswa yang mempunyai kemampuan dan kemauan mengikuti olimpiade sains nasional cabang geografi tingkat sekolah. Hasil seleksi diperoleh 5 siswa potensial yang mewakili sekolah. Metode yang digunakan dalam kegiatan pendampingan meliputi pemberian informasi, tanya jawab, diskusi dan praktik. Pelaksanaan pendampingan selama 8 kali pertemuan, proses pendampingan berjalan dengan baik dan lancar, setiap pertemuan dihadiri oleh kelima siswa yang dipersiapkan. Semua siswa sangat antusias mengikuti kegiatan, terlihat dengan adanya tren respon positif pada diskusi pemecahan soal, siswa dapat beradaptasi dengan cepat terhadap berbagai soal yang berbeda. Kesimpulannya, siswa sudah terbiasa dan terlatih menyelesaikan soal dengan cepat dan tepat serta menemukan trik cara mudah menyelesaikan soal, walaupun masih harus terus berlatih sendiri untuk menghadapi olimpiade sains cabang geografi tingkat kabupaten/kota.

Abstract

Oceanographic parameters are related to the distribution of fish in the waters. The purpose of this study was to analyze the distribution trends of sea surface temperature (SST) and chlorophyll-a (CHL) and to determine the spatial-temporal correlation with the catch of yellowfin tuna. This research took place in WPP 573 and 713 between the north and south of the Alas Strait. Remote sensing methods and statistical regression analysis for SST and CHL in 2023 over 12 months. The penetration results of Aqua MODIS in 2023 show the highest fluctuation SST trend in December (30.71°C), the lowest in August (27.3°C). The highest CHL distribution occurred in December (37.81 mg/m3), and the lowest in February (0.66 mg/m3). The results of linear regression analysis between SSTs; CHL; SST and CHL, for yellowfin tuna fishing, obtained a correlation coefficient (r) of 0.421 each; 0,476; 0.623. Conclusions: 1). The relationship between SST and CHL with yellowfin tuna is in the strong category; 2). The fluctuating catch of yellowfin tuna causes the CHL and SST trends to change every month. CHL and SST values were highest in December, but they did not have a major effect on catches.

Abstract

The counseling conducted in Mambalan Village located at SD No. 1 Mambalan aims to reduce stunting rates through: educating elementary school students about the benefits of fish for health, fostering children's interest in consuming fish regularly, encouraging healthy living behavior from an early age through nutritious diets. The implementation method is carried out by means of Interactive Counseling, Educational Media, Educational Games and Quizzes and Practice (demonstration). This counseling succeeded in increasing the awareness of students of SD Negeri 1 Mambalan about the importance of fish consumption. It is hoped that activities like this can be carried out periodically and involve the role of parents and the school community so that nutritional messages can be applied in everyday life.
