Kegiatan penangkapan ikan oleh nelayan harus memahami mengenai ukuran dan spesies ikan yang layak tangkap. Oleh karena itu nelayan perlu mengetahui mengenai selektivitas suatu alat tangkap yang akan dioperasikan. Hal ini dapat menyebabkan kerusakan lingkungan dan dapat menyebabkan kepunahan terhadap suatu spesies ikan. Penelitian ini dilakukan dengan tujuan untuk mengetahui selektivitas alat tangkap rawai dasar di Deah Raya. Penelitian ini dilakukan pada bulan Mei-Juni 2024. Lokasi penelitian di Deah Raya, Kecamatan Syiah Kuala, Kota Banda Aceh. Metode yang digunakan pada penelitian ini adalah metode wawancara dengan data sheet. Data yang dikumpulkan adalah data primer dan data sekunder dengan jumlah data sebanyak 86. Data primer diperoleh dari hasil wawancara nelayan dan pengukuran hasil tangkapan. Data sekunder terdiri dari jumlah kapal yang beropersi dan jumlah nelayan. Analisis data pada selektivitas alat tangkap rawai dasar dianalisis dengan menggunakan formula selektivitas alat tangkap ikan Spare dan Venema 1999. Berdasarkan penelitian yang telah dilakukan terhadap selektivitas rawai dasar yang dioperasikan nelayan di Deah Raya dengan ukuran mata pancing no.7 dan no. 9, dapat disimpulkan bahwa: ada 12 spesies hasil tangkapan alat tangkap rawai dasar yang dioperasikan nelayan Deah Raya yaitu kuwe, barakuda, asuan, kakap, kerapu, gabus laut, bandeng laut kurisi, kerisi basi, todak, ayam ayam dan pandan. Rawai dasar memiliki selektivitas tinggi, hal ini didasari pada nilai selektivitas di setiap mata pancing yaitu mata pancing no.7 dengan nilai 1 dan mata pancing no.9 adalah 0,9 menunjukkan selektivitas optimal.

Brine shrimp (Artemia salina) cytotoxicity assays (BSLT) are one of the commonly used cytotoxic test methods to assess a plant extract's pharmacological activity and toxicity. Thus, this study aimed to examine the toxic levels of Kecubung (Datura metel) leaves extracted using different solvents, namely ethanol and ethyl acetate. The results showed that the LC50value of flower ethanol, flower ethyl acetate, leaf ethanol, and stem ethyl acetate extracts had an LC50value 1000, which was included in the toxic category. The LC50value of flower ethanol is 121.044 ppm, flower ethyl acetate 105.89 ppm, leaf ethanol 639.589 ppm, and stem ethyl acetate 635.276 ppm. Ethanol leaf extract at a concentration of 1000 ppm showed the highest mortality with a percentage of 60% of the total number ofA. salina. The flower ethanol extract showed the highest mortality at a concentration of 250 ppm with a percentage of 67% and at a concentration of 1000 ppm with a percentage of 70% of the total number ofA. salina. Meanwhile, flower ethyl acetate and stem ethyl acetate extract at a concentration of 1000 ppm obtained 100% mortality ofA. salinain the first 6 hours. The result shows that the flower ethyl acetate and stem ethyl acetate extract at a concentration of 1000 ppm is very toxic compared to other concentrations.Keywords:ToxicityArtemia salinaLC50Ethyl acetateEthanol

Standar Laik Operasi Kapal Perikanan yang selanjutnya disebut SLO adalah surat keterangan yang menyatakan bahwa kapal perikanan telah memenuhi persyaratan administrasi dan kelayakan teknis untuk melakukan kegiatan perikanan. Penerbitan SLO merupakan salah satu bentuk tindakan pengawasan secara preventif. Tindakan pengawasan secara preventif dilakukan dengan cara memeriksa kelengkapan dokumen dan kelayakan teknis sebelum kapal berangkat. Pengawasan ini bertujuan untuk pengecekan kelengkapan dokumen kapal dan mencegah tindakan pelanggaran dalam penangkapan seperti penggunaan alat tangkap terlarang. Tujuan dari pelaksanaan Praktek Kerja Lapangan (PKL) di Pangkalan Pengawasan Sumber Daya Kelautan dan Perikanan (PSDKP) Lampulo ialah untuk mengetahui alur pengawasan terhadap administrasi BA-HPK keberangkatan kapal perikanan dan penerbitan Standar Laik Operasi (SLO). Metode yang digunakan adalah observasi, wawancara, dilakukan dengan cara melakukan pengamatan secara langsung mengenai pemeriksaan kesesuaian fisik kapal dengan dokumen kapal perikanan. Hasil penelitian menunjukkan bahwa proses penerbitan Standar Laik Operasi yang dilaksanakan di Pangkalan Pengawasan Sumberdaya Kelautan dan Perikanan terdiri dari beberapa tahapan yaitu Standar Operasi Prosedur (SOP) Standar Laik Operasi (SLO), Mekanisme Permohonan Standar Laik Operasi (SLO), Prosedur Penerbitan Standar Laik Operasi (SLO).

This study aims to examine the social and economic conditions of purse seine fishermen at the Fish Landing Base Peudada, Bireuen Regency. The data collection methods used include observation and interviews, employing the Accidental Sampling technique with 40 active fishermen. The data gathered consists of primary data obtained through direct interviews and secondary data from relevant literature. The results of the study show that the purse seine fishermen at Fish Landing Base Peudada have an annual net income of approximately IDR 759,762,000, with a monthly income of around IDR 63,313,500. However, their income per fishing trip is only about IDR 6,331,350, and when divided equally, each fisherman receives approximately IDR 316,568 per trip. Although the monthly income is close to the provincial minimum wage, the average household expenses of the fishermen amount to IDR 3,685,000, indicating that they are still economically insecure. From a social perspective, the study reveals that the majority of the fishermen are aged between 36-45 years, with 53% of them having completed only junior high school. Additionally, 75% of the fishermen live in permanent houses. The longest fishing experience is more than 20 years for 30% of the fishermen. The study finds that the economic conditions of the fishermen are far from prosperous, influenced by high household expenses and the instability of their participation in every fishing trip.
