      Abstract
      Ghost fishing merupakan peristiwa hilangnya alat tangkap berbahan sintetis di perairan, menjadi ancaman serius terhadap lingkungan laut karena alat tersebut sulit terurai dan terus menangkap ikan tanpa kendali. Alat tangkap berbahan sintetis memiliki kekuatan tinggi tetapi berdampak negatif terhadap ekosistem jika hilang. Salah satu alternatif untuk mengurangi masalah ini adalah menggunakan material biodegradable seperti serat rami. Namun, tali rami memiliki kelemahan berupa kekuatan putus yang lebih rendah dan ketahanan yang terbatas. Penelitian ini bertujuan untuk meningkatkan kinerja mekanik tali rami dengan melapisinya menggunakan polyvinyl alcohol (PVA), yang bersifat hidrofilik, biodegradable, dan ramah lingkungan. Hasil penelitian menunjukkan bahwa pelapisan PVA meningkatkan kekuatan putus tali hingga 38,99% dan kemuluran sebesar 32,59%. Umur teknis tali rami berlapis PVA juga lebih panjang (7 bulan 1 minggu) dibandingkan tali rami tanpa pelapisan PVA (5 Bulan 1 Minggu). Penelitian ini menunjukkan bahwa tali rami berlapis PVA dapat menjadi alternatif material biodegradable pada alat tangkap seperti bubu.
       
      Ghost fishing, caused by the loss of synthetic fishing gear in aquatic environments, poses a significant threat to marine ecosystems due to the long degradation time of synthetic materials. While synthetic fishing gear offers high durability, it negatively impacts the environment when lost. A potential solution to this issue is the use of biodegradable materials, such as ramie fiber. However, ramie fiber has limitations, including lower breaking strength and reduced durability. This study aims to enhance the performance of ramie fiber by coating it with polyvinyl alcohol, a hydrophilic, biodegradable, and environmentally friendly polymer. The results showed that PVA coating increased the breaking strength of ramie fiber by 38.99% and its elongation by 32.59%. Additionally, the technical lifespan of PVA-coated ramie fiber was extended to 7 months and 1 week, compared to 5 months and 1 weeks for uncoated fiber. These findings demonstrate that PVA-coated ramie fiber is a viable alternative for biodegradable fishing gear materials, such as bubu traps, supporting sustainable fisheries and mitigating ghost fishing impacts.
