Abstract

Potential crustacean resources in Palabuhanratu Bay are quite abundant, but traditional krendet traps are less effective because they lack protection and space dimensions. This study aims to compare the effectiveness of 1-door and 2-door of 2-deck hoopnet trap on crustacean catches. The experimental fishing method was conducted using 3 units of 1-door and 3 units of 2-door of 2-deck hoopnet traps for 20 trips in the waters of Palabuhanratu Bay. Data collected included the number, weight, and type of crustaceans caught. Data analysis used the Mann-Whitney non-parametric test to compare catches between the two trap types. The results showed that the 2-door had a higher number and weight of catches than the 1-door, with a production margin of 43.48% for number of fish and 69.49% for weight (kg). The dominant species was star crab (Portunus sanguinolentus), with more fingerlings caught in the 2-door of 2-deck hoopnet trap. Although statistical tests showed insignificant differences, the productivity of 2-door of 2-deck hoopnet traps tended to be better. In conclusion, the use of 2-door of 2-deck hoopnet traps is more effective in increasing crustacean catches and is recommended for use by fishers in the study area. Key words: 2-deck hoopnet, crustaceans, experimental fishing, traps

Abstract

Previous research on comparing 2-decks hoopnet traps compared to traditional hoopnet traps with frozen bait boosters demonstrated an increase in crustacean catch yields. The present study represents a further development of that earlier work. This research was conducted to determine differences in catch composition and to assess the catch productivity and fishing effectiveness of 2-decks hoopnet traps with frozen bait boosters (treatment) compared to 2-decks hoopnet traps without frozen bait boosters (control). Data analysis methods employed included descriptive analysis, normality testing, and productivity assessment. Catch composition for the treatment and control 2-decks hoopnet traps, respectively, was as follows: 61.1% and 38.9% for blue swimmer crab (Portunus pelagicus), 55.7% and 44.3% for batik crab, and 60% and 40% for ornate rock lobster. Operation of the treatment 2-decks hoopnet traps under a colony system yielded a greater influence on and a higher number of crustacean catches compared to the control across all trips throughout the study period. Overall catch from the treatment 2-decks hoopnet traps was higher than that of the control. The fishing effectiveness of the treatment 2-decks hoopnet traps relative to the control exceeded 40% in both weight (kg) and number (individuals). Key words: colony system operation, crustaceans, 2-decks hoopnet trap, frozen bait booster

Abstract

Hairtail fish longline fishers in Palabuhanratu make fishing their primary occupation and source of income for their families. However, fishers face various challenges by unstable incomes due to seasonal fluctuations in catchs, low levels of education, and lack of alternative livelihoods. Therefore, this study aims to describe layur longline fisheries activities to classify and analyze the welfare levels of layur longline fishers using parameters from the National Population and Family Planning Board (BKKBN). The research methods included observation and structured interviews, as well as snowball sampling. Data were analyzed using descriptive analysis, welfare analysis according to BKKBN parameters, and Spearman rank correlation analysis to identify indicators that most influence welfare. The results show that layur longline fisheries in Palabuhanratu utilize 3 GT vessels with the main catch being hairtail fish (Trichirus sp.). Hairtail fish longline fishers in Palabuhanratu are categorized as Pre-Prosperous Families 6%, Prosperous Families I 53%, Prosperous Families II 38%, and Prosperous Families III 3%. There are three indicators that most influence the level of welfare with a moderate to very strong relationship, namely indicators 10, 11, and 9, the very strong relationship is in indicator 10 with a correlation coefficient of 0.804. Key words: BKKBN, Palabuhanratu fishers, layur longline, level of fisher's welfare

Abstract

Banda Sea is one of most important fishing grounds for Euthynnus affinis in Indonesia; however, information on its potential habitat distribution and response to climate change remains limited. This study aimed to analyze current potential habitat distribution of E. affinis based on oceanographic conditions and to project future habitat suitability under climate change scenarios for the 2030–2040 period. Habitat suitability was modeled using ‘Maximum Entropy’ (MaxEnt) approach with fish occurrence data collected from 2017 to 2022 and environmental variables including sea surface temperature, chlorophyll-a, sea surface salinity, current velocity, and bathymetry. The model demonstrated good predictive performance, with an Area Under the Curve (AUC) value of 0.794. Sea surface salinity and sea surface temperature were identified as the primary environmental factors influencing the distribution of E. affinis. Optimal habitat conditions were associated with salinity of 33–34 PSU, sea surface temperatures of 30–31 °C, and current velocities of 0.05–0.20 m s⁻¹. Under present environmental conditions, suitable habitats were primarily concentrated in the western, northwestern, and southwestern parts of the Banda Sea. Future projections indicated that the Banda Sea is likely to remain a suitable habitat for E. affinis under all climate change scenarios, although shifts in habitat quality and spatial distribution are expected. Among the projected scenarios, SSP2-4.5 maintained relatively favorable habitat conditions, whereas SSP4-6.0 showed the greatest decline in habitat suitability. These findings provide valuable scientific information to support climate-adaptive fisheries management through the identification of potential future habitats for E. affinis.

Abstract

Amagarapati Fish Landing Base is the only official fishing port in East Flores Regency and has a high intensity of operational activities, which potentially generate various occupational hazards and safety risks. This study aimed to identify potential hazards and risks in each working area of the Amagarapati Fish Landing Base. The study was conducted from November to December 2025 using field observations, interviews, and risk assessment through the Hazard Identification and Risk Assessment (HIRA) approach involving 42 fishers, 4 technical staff, and 1 port manager. The results showed that all working areas were exposed to hazards originating from physical, chemical, biological, ergonomic, and psycho-social factors. Most of the identified risks were categorized as low, however, several moderate risks were identified, including lower back pain and postural disorders in the fish unloading area (33.74%), dehydration and heat stress in the parking area (36.88%), occupational accidents during nighttime activities at the wharf (43.54%), and back injuries caused by manual material handling at the wharf (34.69%). The wharf, fish unloading area, and parking area were identified as priority areas for occupational safety risk control within the port.

Abstract

Fish transportation requires adequate transportation modes to ensure that fish transport activities run smoothly, yet every mode carries inherent risk. This study aimed to determine the risk level of fish transportation modes during the transport of fish from Panggang Island to Muara Angke Market. The research was conducted in March-April 2023 using a case-study method with a purposive sampling approach involving 15 respondents: fishermen, middlemen, porters, a crew member, a driver, and traders. Data were collected through direct observation and structured interviews. Risk assessment applied a semi-quantitative analysis based on the Fine (1971) method, calculating probability, exposure, and consequences. Seven fish transport modes were identified: baskets, cool boxes, wooden carts, passenger boats, pick-up trucks, cart wheel, and fibre tubs. Of 40 activity steps assessed across seven stages, 32 had an identified hazard and 8 had none; overall, 39 steps (97.5%) were acceptable and 1 (2.5%) substantial. The substantial risk was the boat sinking, colliding, or catching fire while sailing to Kali Adem Port (risk value 150), as the boat is a shared passenger-and-cargo vessel with no dedicated fish-carrying compartment. Among the identified hazards, human error was the dominant factor (51.4%), followed by technology (45.9%) and natural factors (2.7%). Key words: fish transportation, Panggang Island, risk level, semi-quantitative analysis

Abstract

Entrance orientation, hydrodynamic loading, and bottom sliding are critical constraints in trap development. This study developed a three-entrance hexagonal trap, audited its component-level hydrodynamic resistance, evaluated sliding sensitivity under alternative bottom-contact assumptions, and conducted preliminary field trials. Prototype development was undertaken from December 2024 to February 2025 at “Balai Besar Penangkapan Ikan’s” workshop and at north of Semarang waters. The rigid hexagonal prism had 0.75 m sides and height, a maximum span of 1.50 m, an 8 mm steel frame, 2 inch polyethylene netting, a mass of 6 kg, and material costs of IDR 680,000. At a design current of 1.5 m s⁻¹, consistently recalculated drag was 26.73 N for the netting and 12.87 N for the frame, giving 39.60 N total drag; the netting contributed 67.5%. Depending on the assumed bottom coefficient (0.61-0.75), the sliding safety factor was 0.78-0.96 for the original mass and 0.97-1.20 after adding 1.5 kg of ballast. Catch was recorded in three of eight settings and comprised 31 unidentified individuals consisting of crabs and fish. The prototype was constructible and deployable, but the absence of a control trap, standardized soak time and bait, species and size identification, and near-bottom current measurements prevents conclusions about comparative catch efficiency, selectivity, and field stability. The design should therefore be regarded as a proof of concept requiring controlled experimental validation. Key words: bottom stability, drag force, hexagonal trap, prototype design, three entrances

Abstract

This study aims to analyze the production factors influencing the catch of skipjack tuna (Katsuwonus pelamis) and to determine the optimal level of fishing effort at the Cilacap Oceanic Fishing Port (PPS Cilacap). The research employs a survey approach utilizing a quantitative descriptive method for data analysis. Primary data were obtained directly through interviews with 65 purse seine fishermen, complemented by secondary data on production volume for the 2020–2024 period. To analyze the data, the analytical instruments used include the Catch Per Unit Effort (CPUE) calculation and the Cobb-Douglas production function model. The results indicate that the CPUE value increased over the study period, averaging 6,771.24 tons/trip, which reflects an increase in fishing efficiency. Simultaneously, production factors significantly affect the catch, with dominant variables including the number of trips, vessel size, and engine power. Improving efficiency in the capture fisheries business and protecting the sustainability of skipjack tuna stocks heavily depend on the extent to which the optimization of production factors and minimization of waste are executed. Key words: CPUE, efficiency, fishing port, production factors, skipjack tuna

Abstract

Conflagrations caused by workshop-related activities represent one of the workplace accidents with high potential occurrence at the Nizam Zachman Jakarta Oceanic Fishing Port. Data indicate that two of the six recorded fire incidents during the 2022–2024 period originated from workshop activities. Based on this condition, this study aims to identify potential hazards in operational activities, assess the associated risk levels, and formulate control recommendations for workshop activities at the dock. Data were collected through field observation, interviews, and literature review, and subsequently analyzed using the Hazard Identification, Risk Assessment, and Determining Control (HIRADC) approach. The analysis identified 3 main activities and 15 sub-activities involving varying levels of occupational risk, consisting of 13 low-risk, 1 medium-risk, and 7 high-risk categories. The implementation of the hierarchy of control is projected to measurably reduce the risk levels of those occupational hazards. The findings of this study are expected to serve as a basis for port management in strengthening a more integrated and sustainable occupational health and safety management system. Key words: HIRADC, occupational health and safety, pier, workplace accidents
