Abstract

One of the fishing gear widely used by fisherman in Banten Bay is bottom mini trawl which called jaring arad. The main problem in “jaring arad” fisheries is high bycatch and low selectivity of fishing gear. One effort to reduce high bycatch at jaring arad is the implementation of Turtle Excluder Device (TED. Accordingly, this study aimed to examine community perceptions of the Turtle Excluder Device (TED). Data were collected through interviews with 25 respondents, and the findings were subsequently analyzed using descriptive statistical methods. Research results indicate that 67% of fishermen disagree with the prohibition of jaring arad. However, one of the obstacles to use Turtle Excluder Device (TED) is the limited knowledge and understanding fishers have of the technology. Based on the interview results using the questionnaire, it was found that 61% of the fisherman who participated in the outreach activity had never heard of the TED device, while only 39% had heard of it.  After receiving an explanation during the outreach activity about the use of TED, the majority of participating fishers were willing to try it. Based on the survey, 82% of the fishermen were willing to try the Turtle Excluder Device (TED). Key words: bycatch, jaring arad, selectivity, Turtle Excluder Device

Abstract

Folding crab traps are widely used by Indonesian fishermen because they are easy to construct and operate. Observations suggest that crabs frequently struggle to pass through the entrance channel, as their legs become entangled in the mesh. The spines on the sides of their bodies usually become entangled in the net threads because the entrance is too narrow. Consequently, the chance of crabs being trapped is very low. The objective of the study is first to determine the combination of slope angle and mesh size for the channel that allows for crabs to pass through easily. The study attempted to combine the traverse angles of 20°, 30°, and 40° with mesh sizes of 0.125", 0.35", and 1.25". The second objective is to determine the elliptical or rectangular entry gap that is easy for crabs to pass through. Laboratory-scale research and the research data were analysed parametrically using two-way ANOVA and Tukey's post hoc test. The results indicated the combination of an angle of 20° and a mesh size of 0.125" was the best configuration, because 26 individual of crabs could pass through the entry gap. The following combination, 20° (0.35") and 30° (0.125"), each passed through 25 crabs. A total of 369 individual of crabs (63.6%) could pass through the rectangular gap, while 211 individuals (36.4%) passed through the elliptical gap. The combination of a 20° angle and a mesh size of 0.125" with a rectangular entry gap is easier for crabs to pass through compared to other combinations.

Abstract

Widespread use of synthetic materials in fishing gear has raised serious environmental concerns due to their non-biodegradable nature. Pineapple leaf fiber is a promising biodegradable material that can be used as a base for ropes in environmentally friendly fishing gear. This study aimed to analyze the physical and mechanical properties of PALF rope, particularly breaking strength and elongation, with surface treatments using tar and chitosan. The methods included specimen preparation, coating, freshwater immersion, and mechanical testing following SNI ISO 1805:2010. The results showed that chitosan coating improved breaking strength by 18.78% and elongation by 25.56% compared to the control. Coating treatments also affected the stress values, with the most significant reduction observed in tar-coated samples (57.89%). Immersion tests over five weeks indicated a decline in tensile strength and elasticity, with the control group showing the highest coefficient of determination (R² = 0.9145). Although chitosan-coated ropes degraded more quickly in terms of tensile strength, they maintained elongation capacity up to week 12. These findings suggest that chitosan-coated PALF ropes have strong potential as a biodegradable material for sustainable fishing gear. Key words: breaking strength, elongation, environmentally friendly fishing gear, pineapple leaf fiber

Abstract

Ghost fishing occurs because most fishing gear made from synthetic materials is difficult to degrade in the ocean, threatening the sustainability of marine ecosystems. This study aims to determine the physical and mechanical properties of polyvinyl alcohol (PVA)-coated cotton ropes. The PVA coating process aims to enhance the breaking strength, elongation, and degradation resistance of cotton ropes. PVA-coated ropes exhibited an average breaking strength of 42,68 kgf, a 94,26% increase compared to uncoated ropes. The elongation of PVA-coated ropes reached 20,11%, higher than the control ropes, which had an elongation of only 13%. Immersion tests in seawater demonstrated that the technical lifespan of PVA-coated ropes extended to 54 weeks after immersion, whereas uncoated cotton ropes lasted only 17 weeks.

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
