Coating of coconut coir rope as a material for fishing gear is carried out to inhibit the decomposition process and increase the breaking strength and elongation of the rope. In this study,the coating of coconut coir rope using chitosan as an antimicrobial is expected to inhibit the growth of micro-organisms. This study aims to determine the elongation and breaking strength of chitosancoated coconut coir ropes. The research method used is experimental. Data analysis used the Kolmogorov–Smirnov normality test and RAL (Completely Randomized Design)- to determine the effect of chitosan coating on the elongation and breaking strength of coconut fiber ropes. The results showed that the chitosan coir rope had a dark brown color, while the control coir rope had a light brown color. The direction of the twist is "S", with a "hard" type of twist so that the rope tends to be stiff. The fiber type is staple fiber (short fiber). The elongation of the chitosan coir rope was 10.21 cm, 17.55% higher than the untreated coconut coir rope, which was 8.68 cm. The average breaking strength of chitosan coir rope was 37.41 kgf or 11.87% higher than untreated coconut coir rope, which was 33.44 kgf. Keywords: elongation, breaking strength, chitosan, chitosan coconut fiber rope.

The purpose of this study determined the swimming layer and distribution of pelagic fish in the waters west of the Flores Sea through acoustic detection. Experimental fishing is a method used with two data analyses: 1) analysis of acoustic data at sampling stations with stationery techniques; and 2) analysis of acoustic data along transects between stations. The detection results at stationery 1 showed a very low abundance of pelagic fish, distributed at layer 4 (150-200 m) at night and suspected to be a large pelagic type of tuna with a small amount. The detection results on stationery 2 and stationery 3 are relatively the same, showing a relatively higher abundance compared to stationery 1. Detection results for transects between stations 1-2, 2-3, 3-4, and 4-5 starting from Dewakang waters to east of Takarawataya waters did not detect schooling fish but only single fish. On transects between stations 5-6 very low abundance, the highest mean abundance of 0.5 fish/1000 m3 was detected at layer 4 (150-200 m). On transects between stations 6-7 the abundance was not too high, the highest mean abundance was detected at layer 3 of 10.8 fish/1000 m3. The transect between stations 7-8 is the highest abundance of all transects, the highest abundance average value detected at layer 3 is 20.3 fish/1000 m3. On transects between stations 8-9 the abundance was not too high, schooling tended to be present in all layers, and the highest mean abundance was detected at layer 4 of 1.3 fish/1000 m3. The results of the study concluded that the abundance of pelagic fish in the western Flores Sea is distributed in layers 3 and 4 (100-200 m).

Blue swimming crab is one of the capture fisheries sector leading commodities in Banten Bay which is caught using gill nets and collapsible traps. The risk of lost fishing gears during operation is very high, both due to the bad weather and interactions with other fishing gear. The Abandoned, Lost or Discarded Fishing Gear (ALDFG) contributes significantly to the abundance of marine plactics in the world which has a negative impact on the sustainability of fish resources, water quality and endangers the safety of navigation. Nevertheless, there have been no mitigation activities and efforts to reduce ALDFG in the Banten Bay. This study aims to identify the global causes of lost fishing gear derived from blue swimming crab fisheries in Banten Bay. Data were collected around the Archipelagic Fishing Port (PPN) of Karangantu in May-June 2022. In-depth interviews were conducted with 28 respondents who were selected purposively and the results were analyzed descriptively. The results showed that generally, the causes of lost gear were conflicts with other fishing gear which constitute 64%, whilst human errors during fishing operations and bad weather contributed 19% and 17%, respectively. Keywords: ALDFG, conflict, blue swimming crab, lost gear.

A shipyard is where ship construction, repair, and maintenance are carried out. Job incidents commonly happen because of human error and lack of security. A company should create a safe environment by reassuring their employees’ health and safety environment, the docking area of PT Perikanan Indonesia included. The purposes of this study are to identify the high-risk situation that can occur to the employers at the docking area. The analysis methods used are descriptive analysis and Job Safety Analysis (JSA). The results showed that many employees of the docking area lack awareness of job safety procedures. Fatal failure could occur during docking operations, and it is caused by the dock staff not being familiar with the safety equipment used on heights. It recommends wearing personal protective equipment and conducting technical and administering inspections to prevent many accidents during docking.

Rabbitfishes (Siganids) fishing activities tend to increase and potentially impact fish target and ecosystem, which is indicated by changes in population size and structure and the trophic level of the catches. Scientific information on Siganids fishing techniques and its ecological impact are limited. The aims of the study are: (1) to describe technical fishing aspects of Siganids fishery; (2) to estimate parameters of length at first maturity (Lm) as catch size limit indicators for this fish target; (3) to evaluate the impact of fishing on food chain balances (trophic level) the fish resources in this study area. The Siganids fishing techniques were observed during the field study. The catch of Siganids species and other fishes from various fishing gears were sampled, then identified and calculated individually. The samples of Siganids fish were also measured for its length and weight. This study showed that the fishers were used three kinds of fishing gears to target the Siganids fish, i.e., rope traps, bamboo traps, and spear gun. There were five species of Siganids caught during the research, they are: Barhead spinefoot (Siganus virgatus), Goldspotted spinefoot (S. punctatus), Streaked spinefoot (S. javus), Orange-spotted spinefoot (S. guttatus), and White-spotted spinefoot (S. canaliculatus), with the Lm value of 3.5, 22.8, 30.6, 21.2, and 20.8 cm, respectively. All catches of the Siganids exceeded the catch size limit (Lm), except for S. punctatus and S. Javus which was only 65.51% and 4.00% of the respective catches were acceptable in size. Finally, the Siganids fishing activities in the study area potentially impacted the ecological function of natural food chain balance (trophic level). It was indicated by the dominance (48%) of the catches on trophic level 3. Keywords: fishing impact, rabbitfish, Siganidae, size limit, trophic level

Oyster culture is an aquaculture activity that is mostly carried out in Japanese waters. While in Indonesia, oyster shells are widely consumed, but they have not been produced through the culture process but are caught on the high seas. This study aims to determine how the application of technology and transportation in the culture and sale of oyster in Japan. Based on literature studies and activities at the Kamashima-Japan company, transportation is an important part of oyster farming activities. Oyster transportation technology is currently carried out in two areas, namely sea and land, using open and closed dry transportation methods. Sea transportation uses Hydraulic Cranes for Shipboard Use (Marine Cranes) technology which is applied to special vessels measuring 6-7 GT with the classification of Truck-mounted cranes, while land transportation uses Styrofoam boxes equipped with ice blocks to immobilize the temperature. The size of the wind that blows in the sea, the time of pick-up and delivery, and the number of oyster shells required are important factors in these transportation activities.

The fisheries management based on the Ecosystem Approach to Fisheries Management (EAFM) can be implemented to optimize the potential of fisheries resources. The purpose of this research is to apply EAFM indicators for analyzing surface gillnet fishing gear in Bagan Siapi-api waters, especially fish resources, fishing methods, habitats, and ecosystems. The evaluation of fishery management status was carried out using multi-criteria analysis (MCA) through the development of the composite index of each EAFM indicator. The results showed that the surface gillnet fishing gear was dominant with 1,645 tons of fish caught in 2019 by fishermen in Bagan Siapi-Api Waters. The composition of the catches was sukain fish (Eleutheronema tetradactylum), flounder fish (Pleuronectiformes), and tornfish (Bovichthyidae). Based on the analysis of the EAFM indicators, the value of the domain of fish resources, habitats, and ecosystems, as well as fishing methods has a value between 2 and 2.5. This indicated that the status of ecosystem-based area management in the waters of Bagan Siapi-api is in the medium-good category. Keywords: Bagan Siapi-api, EAFM, Fisheries Sustainability, Gill Net

The Saleh Bay is one of the bays in West Nusa Tenggara utilized as the grouper fishing ground. However, in the previous spawning potential ratio study, some grouper species have been overexploited in Saleh Bay. This study aimed to estimate the status of grouper utilization with a catch per unit effort (CPUE) approach and the spatio-temporal fishing intensity of grouper in fishing grounds in Saleh Bay. Data were gathered using the fish landing data and geo-reference of fishing ground grouper in Saleh Bay. This study used several methods: descriptive analysis, catch per unit effort, and spatial-temporal analysis. The result showed that the catch unit effort positively impacts production, with the increasing trend of grouper fishing in Saleh Bay waters. The CPUE value in 2016 was 2.82 kg/trip, while in 2020, it increased to 3.99 kg/trip. Spatially and temporally, fishers caught grouper around small islands such as Liang Island, Dempu Island, Lipan Island, Takat Nusa Pudu, and Rakit Island. The highest intensity of grouper fishing around the marine protected area, namely Rakit Island, Liang Island, and Ngali Island. Keywords: catch per unit effort, fishing ground, grouper, Saleh Bay

The increase in fishing activities of fishers in the Lebak Regency is facilitated by the Binuangeun Fish Landing Base (PPI). Every year, there is a growth in fish production at PPI Binuangeun. Production from 2015 to 2019 increased by 671 tons (13.55%). This study aims at formulating and determining strategies for improving the PPI Binuangeun class category. A survey approach was used in this study. Samples were taken by purposive sampling. The improvement in PPI class were categorized using the Analytical Hierarchy Process (AHP) scoring method. Results showed that the score was 254 with a success value of 251-300, indicating high potential and standards fulfillment. Thus, PPI Binuangeun can be transferred and upgraded to PPP (Coastal Fishery Port). The results of the AHP suggested that the central priority values for the development of PPI Binuangeun include: supply, auction, landing and marketing activities with the priority value of 0.585. Subsequently, another strategy is expanding the port area with score of 0.409. The support of relevant stakeholders for the development of the fishing port is needed to realize the aspirations of the central and local governments.

Every year, there is a growth in fish production at PPI Binuangeun. Production from 2015 to 2019 increased by 671 tons (13.55%). This study aims at formulating and determining strategies for improving the PPI Binuangeun class category. A survey approach was used in this study. Samples were taken by purposive sampling. The improvement in PPI class were categorized using the Analytical Hierarchy Process (AHP) scoring method. Results showed that the score was 254 with a success value of 251-300, indicating high potential and standards fulfillment. Thus, PPI Binuangeun can be transferred and upgraded to PPP (Coastal Fishery Port).

The potential condition of fishery sector is indeed quite large in Central Bangka Regency. The majority of fishermen in Central Bangka Regency still use traditional fishing gear and simple fishing technology. The number of fishing units used in Central Bangka Regency consists of 370 units of lift net, 1,085 units of gillnets, 129 units of bubu, 60 units of sero, 125 units of fishing rods and 4 beach seines with a fleet of 1,767 (DKP Central Bangka Regency 2019). These types of fishing gear need to be assessed for performance and selected for superior fishing units as a form of optimizing to find out the strategy for developing appropriate and superior fishing units for the fisheries sector in the mining sector in Central Bangka Regency. The method of collecting data on fishing units was carried out by accidental sampling. The number of samples taken according to the category of fishing units were 20 units of lift net, 58 units of gill nets, 8 units of bubu, 3 units of sero, 10 units of fishing rods and 1 beach seines. Based on the results of standardization of technical aspects, environmental aspects, social aspects and economic aspects, the analysis of fishing gear gillnets is the most appropriate fishing gear to be developed in Central Bangka Regency with VA = 13.26 which makes gillnets gear priority I. Priority fishing gear II is a fishing rod with VA = 12.87 and priority III is a lift net with VA = 11.56. Keywords: superior fishing gear, sustainable fishing, Central Bangka Regency
