Abstract

One of the problems faced in the development of the marine and fisheries sector nationally is the low quality of the fish capture due to the limited capacity and quantity of available port infrastructure resulting in the decrease in competitiveness. The data in this study were related to fish capture from fishing boats to wholesalers. The data obtained was observation of the location of the vessel, the fish auction place, and the marketer. The types of fish taken were Kurisi (Nemipterus pneumatophores), Biji Nangka (Upeneus mullocensin), Kapas-Kapas (Gerres erythronium), Bawal Putih (Pampus argenteus), Kembung (Rastrelliger spp). Fish examining was done by looking at the organoleptic and pH values. The pH value was obtained by testing the pH meter, while the organoleptic value was obtained by observing the physical condition using a score sheet. To determine the magnitude of the influence of facilities on fish quality, and the correlation between organoleptic values and pH, an analysis using simple linear regression was conducted. The average organoleptic value of fish while on the boat, when distributed, and when in the marketplace were 8,248; 7,024; and 6.6 respectively. Meanwhile, the average pH value was 7.05; 5.51; and 5.15. The quality of fish caught at Class A Fishing Port of Belawan is still of good quality. The pH test showed decline in pH value ever since the fish was brought to the port until they were marketed. The influence of facilities on the fish organoleptic and pH value are 98.3% and 96%. Thus, facilities significantly affect fish quality at Belawan Fishing Port. Between pH and organoleptic values showed a positive correlation, hence when the pH value decreased, the organoleptic value also dropped.Keywords:Belawan Fishing PortEast WatersFacilities InfluenceFish Quality

Abstract

Indonesia Fisheries Management Area 718 (IFMA-718), located in the Arafura Sea, is known for its high marine biodiversity and serves as a strategic fishing ground. However, the lack of fishing gear selectivity in this area poses a significant threat to the sustainability of marine resources. This study aims to evaluate the selectivity of purse seine fishing gear through biodiversity analysis using the Shannon-Wiener diversity index (H’), evenness index (E), and dominance index (C). Data collection was conducted from September 2023 to March 2024 in the Arafura Sea using a 149 GT purse seiner. Catch data were categorized into target species, bycatch, and discards. The results showed that the values of H’ ranged from 0.77 to 1.40, E values were mostly greater than 1, and C values were below 0.5. These findings indicate a high species diversity and evenness, alongside low dominance, suggesting a relatively balanced community structure. However, such diversity also reflects the low selectivity of the fishing gear, which captures both target and non-target species, including demersal and benthic organisms. In conclusion, the purse seine gear used in IFMA-718 is considered to have low selectivity and is potentially harmful to non-target marine ecosystems. This study provides essential insights for improving selective fishing practices and implementing sustainable fisheries management in the region.

Abstract

The escalating need for animal protein has stimulated the growth of the capture fisheries industry. However, undue carelessness concerning the maintenance and operation of fishing vessels often results in scenarios that pose serious risks, even leading to fatal accidents. In Karawang District, the high spirit of fishermen in setting sail plays a major role in boosting the productivity in the capture fisheries sector. Yet, the awareness of the importance of using personal safety equipment while at sea remains disappointingly low. The Fish Capture Study Program of the Politeknik Kelautan dan Perikanan Karawang set out to organize a training sessions aimed for enhancing the fishermen’s awareness of safety during their voyages. These sessions are a manifestation of the social responsibility in empowering the community and promoting sustainable development. Through presentations, and direct demonstrations, fishermen are instructed on various aspects of safety during their voyage. The training includes techniques for self-preservation at sea, use of the red hand flare, activation of parachute signals, and smoke signals during emergencies, as well as the use of life buoys and life jackets to enhance safety at sea. This community service activity was attended by 20 fishermen residing on the coast of Karawang District. The initiative attempts to strike a balance between the urgency to meet the growing demands for animal protein, and the obligation to promote safe and sustainable practices in the capture fisheries sector.

Abstract

Penelitian ini bertujuan meningkatkan pemahaman dan keterampilan numerasi siswa melalui penerapan model pembelajaran berbasis masalah dengan bantuan media ICT. Metode yang digunakan dalam penelitian ini adalah Penelitian Tindakan Kelas (PTK), yang akan dilaksanakan dalam dua siklus. Setiap siklus terdiri dari empat tahap, yaitu perencanaan, tindakan, observasi, dan refleksi. Materi yang diajarkan meliputi sistem persamaan linier, dengan fokus pada pengembangan kemampuan siswa dalam memodelkan masalah nyata ke dalam persamaan matematis dan menyelesaikan sistem persamaan tersebut. Penelitian ini melibatkan 36 siswa kelas X dari SMA Negeri Srijaya Negara Palembang. Pengumpulan data dilakukan melalui observasi, tes, wawancara, dan dokumentasi, yang kemudian dianalisis secara kuantitatif dan kualitatif. Hasil siklus I menunjukkan bahwa metode Problem-Based Learning (PBL) meningkatkan keterlibatan sebagian siswa dalam pembelajaran dengan metode grafik meskipun terdapat kendala pada pengelolaan waktu. Hasil dari siklus II menunjukkan peningkatan pemahaman siswa terhadap materi SPLDV dan sistem pertidaksamaan linier dua variabel berdasarkan kenaikan skor rata-rata tes dibandingkan dengan siklus I. Kesimpulan dari penelitian ini adalah metode Problem-Based Learning (PBL) secara efektif meningkatkan keterlibatan siswa, pemahaman konsep, dan kemampuan pemecahan masalah pada materi Sistem Persamaan Linier Dua Variabel (SPLDV) dan sistem pertidaksamaan linier dua variabel dengan pengintegrasian GeoGebra dalam memperkuat kemampuan numerasi siswa.
