GAPS IN SHARK LANDING RECORDS AND TRADE STATISTICS: EVIDENCE FROM OCEAN FISHING PORT NIZAM ZACHMAN
type: item
description: Shark product traceability is a critical component in supporting sustainable shark fisheries management, particularly to prevent unreported, underreported, or misreported fishing practices. This study analyzes shark landing recording practices at the Nizam Zachman Ocean Fishing Port (PPS Nizam Zachman), Jakarta, one of Indonesia’s main fisheries landing ports. The research was conducted through two weeks of field observations and in-depth interviews with data enumerators, port officers, and fisheries stakeholders. The results indicate that shark landing records still rely on general fish landing standard operating procedures and lack specific guidelines for sharks, particularly for species-level identification and recording of physical condition. Sharks were frequently landed as juveniles, in non-intact conditions, and mixed with other fish species, complicating identification and increasing the risk of data inaccuracy. These conditions may undermine shark product traceability systems and sustainable shark resource management. This study recommends the development of shark-specific landing recording SOPs, capacity building for enumerators through species identification training, and the provision of visual documentation tools to improve data accuracy at landing sites. Key words: shark landing records; shark traceability; unreported fishing

TECHNICAL ANALYSIS OF SEA CUCUMBER CATCH AND PROCESSING ONBOARD FISHING VESSELS AT WEST COAST WATERS OF SUMATERA
type: item
description: Sea cucumbers are high value fishery commodities that play an important role in international trade. Despite their significant economic contribution, scientific information regarding the technical aspects of sea cucumber harvesting and onboard processing remains limited. This study aims to examine the technical practices of sea cucumber harvesting and onboard processing through a case study in the West Coast waters of Sumatra. The research was conducted in October 2025 in the waters of Tello Island, South Nias, using direct observation methods by participating in the entire operational sequence of sea cucumber harvesting and processing onboard fishing vessels. Primary data were collected through field observations and interviews with the vessel captain and crew members, while secondary data were obtained from fishing operation documents. The results indicate that the operational workflow of sea cucumber harvesting is systematically organized, encompassing preparation stages, compressor-assisted diving operations, and the regulation of divers’ working and resting periods. Onboard sea cucumber processing involves sequential stages of cleaning, boiling, soaking in saline solution, smoking, and drying, utilizing simple facilities and traditional methods. The technical workflows of harvesting and processing, as presented in tabular form, represent actual operational conditions in the field and provide an essential basis for understanding operational effectiveness, existing limitations, and the potential for sustainable development of sea cucumber fisheries.

FISHERMEN COMMUNITY PERCEPTION ON TURTLE EXCLUDER DEVICE (TED) IMPLEMENTATION AT CITUIS FISHING PORT, TANGERANG
type: item
description: 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

type: item
description: Sungai Gayung Kiri Village in Rangsang Subdistrict, Meranti Islands Regency, has great fisheries potential, with most of the community relying on capture fisheries using traditional fishing gear such as belat (set nets). This area has experienced severe coastal abrasion, which has led to mangrove degradation, shifts in fishing grounds, and a decline in catch production. This research was conducted in 2025 in the coastal waters of Sungai Gayung Kiri. The purpose of this study was to determine the sustainability status of belat fishing gear based on ecological, economic, and technological dimensions. The method used in this study was a survey method through direct field observation and interviews with fishermen. The data collected included the number of fishing units, production trends, environmental parameters, and sustainability attributes. The data were analyzed using Multidimensional Scaling (MDS) with the RAPFISH approach. The results showed that the ecological dimension had a value of 20.02%, categorized as unsustainable. The economic and technological dimensions obtained values of 58.34% and 57.99%, respectively, and were categorized as moderately sustainable. This study concludes that although belat remains an important traditional fishing gear, its sustainability is still low, particularly in the ecological aspect. The findings indicate the need for sustainable fisheries management, including mangrove conservation, regulated resource utilization, and improved fishing gear technology.

type: item
description: Light fishing are an essential piece of equipment for purse seine operations because they increase catch efficiency by drawing schooling fish with their phototaxis response. Nonetheless, variations in light design and operation significantly affect fishing productivity. The purpose of this study was to examine the fishing lights' operational efficiency and construction features on the KM. Mutiara Sejati purse seine vessel that operates at the Bajomulyo Fishing Port in Central Java. Data was collected through organized interviews with the captain and crew, technical measurements of the lighting system, and direct field observations during ten fishing expeditions. According to the findings, the ship used a multi-light system with 40 units: 16 funnel lamps (corong), 16 galaxy lamps, 8 LED lamps, and 1 raft light. Before the net was deployed, illumination was progressively reduced using galaxy lamps, LED lamps, and finally funnel lamps to optimize fish aggregation. Fish were located using fish finders, and they were concentrated using raft light. According to the study, by keeping fish concentration close to the vessel, this sequential light operating strategy increased catch efficiency. These results offer purse seine fishermen useful advice on how to maximize fishing light operations and increase catch productivity.

MORPHOLOGICAL ANALYSIS OF Bruguiera gymnorrhiza AT TUNDA ISLAND, BANTEN, IMPLICATIONS FOR MANGROVE ECOSYSTEM CONSERVATION
type: item
description: Mangrove ecosystems play an important role as habitats for biota, natural coastal buffers, and carbon sinks. This study examines the morphological and morphometric characteristics of Bruguiera gymnorrhiza at Tunda Island, Serang, Banten, to understand species adaptation to dynamic tidal conditions and the effects of plastic waste accumulation on vegetation growth. Field observations were conducted at six sampling sites using a line transect–quadrat method. Data included measurements of stems, leaves, flowers, and fruits, as well as observations of stomata and cambium. The results showed tree heights of 7–15 m, diameters of 15–123 cm, leaf lengths of 5–21.5 cm, flower lengths of 2.8–5 cm, and fruit lengths of 6–16.3 cm. Anomocytic stomata and active cambium indicate adaptation to high salinity and muddy environments. Differences between the eastern and southern parts of the island, related to hydrodynamics, substrate, and plastic pollution, resulted in higher Bruguiera gymnorrhiza density in the east. The Shannon–Wiener diversity index was low (H’ east = 0.795; south = 0.3466), indicating species dominance. These findings support mangrove management and conservation efforts, particularly through plastic waste reduction and salinity monitoring.

CHARACTERISTIC DESIGN OF SQUID LAMP AS ATTRACTOR USING LIGHT EMITTING DIODE (LED)
type: item
description: Squid jigging fisheries in Indonesia have developed rapidly, leading to a substantial increase in energy consumption due to the growing number of squid jigging units. Traditionally, metal halide (MH) lamps with electrical power ranging from 24 to 30 kW are used as light attractors. This study aimed to design a LED (light-emitting diode) lamp for squid fishing with a light distribution pattern comparable to that of MH lamps and to evaluate its fuel consumption. The research involved the design and construction of an LED-based squid lamp, measurement of light intensity in air, and comparison of fuel consumption between LED and MH lamps under laboratory conditions. Underwater light intensity was measured in the waters of Banten Bay. The electronic system employed components with total LED power of 450 watts. Results showed that the average light intensity of the LED lamp decreased by only 10.57% compared to the MH lamp. The Specific Fuel Consumption (SFC) of MH lamps ranged from 0.00162–0.00176 kg/hp·h, while that of LED lamps ranged from 0.00109–0.00119 kg/hp·h. The LED system achieved a fuel efficiency of 40.54%, indicating a 19.03% improvement compared MH lamps. Further field-scale experiments are required to validate effectiveness in actual squid fishing operations. Key words: intensity, light, measurement, squid

MODIFIED COLLABSIBLE TRAP EFFECTIVENESS FOR BLUE SWIMMING CRAB (PORTUNUS PELAGICUS) FISHING AT BANTEN BAY
type: item
description: The collapsible crab trap commonly used to harvest blue swimming crab (Portunus pelagicus) in Banten Bay employs a 1.0-inch mesh wall, which restricts the escape of undersized crabs. To enhance size selectivity without compromising capture efficiency, a modified trap was developed featuring a 2.5-inch wall mesh and a yellow-colored entrance. Fishing trials were conducted in September 2024 and October 2025 in Banten Bay using trash fish as bait. Data collected included the carapace width and weight of the crabs, as well as the total weight of bycatch. A descriptive analysis and scoring method were applied to evaluate trap effectiveness. The design parameters used in the scoring analysis are the percentage of crab weight, the percentage of bycatch weight, the percentage of crabs legal crab, the percentage of undersize crabs, and the average carapace width of the crab. The t-test equal variance was conducted to compare whether there was an effect of differences in trap designs on the weight of the crab obtained. Results indicated that the modified trap achieved a high effectiveness score (total = 18). The modified trap produced 82% of the total catch weight from target crabs and only 18% from bycatch. The use of a yellow entrance combined with a 2.5-inch wall mesh significantly improved the catch proportion of marketable-sized crabs while reducing bycatch biomass.

type: item
description: Distribution of skipjack tuna (Katsuwonus pelamis) stock, an economically important commodity, has led to a decline in fish size status. Exploitation in the southern waters of Latuhalat village is carried out by various fishing gear, affecting trip and catch production. The study aimed to analyze size distribution, growth pattern, mortality, and sex ratio using Microsoft Excel and FiSAT II software. The results showed a growth coefficient (K) of 0.61 per year and asymptotic length (L∞) of 62.50 cmFL, with a maximum age (t) of 8 years and age at zero length (t0) of -0.23 years. The von Bertalanffy growth equation was Lt = 62.50(1-e^(-0.61(t+0.23))). The cohort pattern consisted of 4 cohorts, with juvenile fish at 23.3 cm and adult fish at 55.5 cm. The fishing mortality rate (F) was 0.03 per year, calculated by subtracting natural mortality rate (M) of 1.07 per year from total mortality rate (Z) of 1.10 per year. The exploitation rate (E) was calculated as E=F/Z, which was 0.03. The sex ratio was 1:1, indicating a balanced population. Recommendation: reduce the catch of adult fish during the third gonad stage to maintain population balance. Key words: Katsuwonus pelamis, Latuhalat waters, population parameters

To meet export standards, this species must fulfill specific quality criteria to be considered suitable for export. This study aims to analyze the fishing season pattern and size structure of catchable Spanish mackerel (Scomberomorus commerson) in the waters of the Riau Archipelago. Data were collected through field surveys, direct observation of catches, and analysis of gillnet vessel logbook records from 2018 to 2022. Fishing productivity was calculated using catch per unit effort (CPUE), and the seasonal pattern was identified using the Simple Moving Average (SMA) method and monthly fishing season index (Mt,b). The results showed that the fishing season for Spanish mackerel occurs from January to May, with the peak season in February. The size structure analysis revealed that 87.6% of the sampled fish were larger than 61 cm, indicating that they had reached first maturity (catchable size). Nevertheless, a portion of smaller fish was still caught, highlighting the need for improved management of fishing gear and fishing grounds to support resource sustainability. These findings, once implemented, are expected to significantly improve the sustainability of Spanish mackerel populations, offering hope for the future of this species. These findings are expected to contribute to the implementation of precision fisheries management in Fisheries Management Area (FMA) 711. Key words: catchable size, catch per uni effort, fishing season pattern, precision fisheries, Spanish mackerel

FISHERMEN’S PERCEPTION ON PORTABLE COOLING MACHINES WITH SOLAR PANELS AT BATU BERIGA, CENTRAL BANGKA REGENCY
type: item
description: This study aims to analyze the perceptions of Batu Beriga fishermen regarding the use of portable cooling machines powered by solar panels as an alternative to ice in handling fish catches. The technology is considered promising as it reduces dependence on ice blocks, lowers operational costs, and helps maintain fish freshness for longer periods. A descriptive quantitative approach was employed, using a structured questionnaire administered to 40 active fishermen with at least five years of fishing experience. Perceptions were assessed through 10 indicators covering functionality, economic benefits, ease of use, compatibility, technical complexity, and impact on catch quality. The results reveal that most fishermen expressed positive perceptions, with the highest agreement on the machine’s function as an ice substitute (95%) and its adaptability to vessel conditions (90%). However, concerns remain regarding the initial investment cost and fabrication complexity, as only 50% of respondents agreed with this aspect. Overall, the findings highlight a strong relative advantage and compatibility, while technical complexity persists as a major challenge. The study underscores the need for policy support in the form of technology subsidies, soft loans, and technical training programs to facilitate wider adoption. Such interventions are expected to accelerate the integration of renewable energy technologies into small-scale fisheries, reduce fishermen’s operational costs, and strengthen post-harvest handling systems. Furthermore, the adoption of solar-powered cooling technology aligns with the Sustainable Development Goals (SDGs), particularly Goal 7 (Affordable and Clean Energy) and Goal 14 (marine ecosystem).

RISK ANALISYS OF DEMERSAL FISHING USING FISH TRAP IN SERIBU ISLAND, JAKARTA
type: item
description: Demersal fish capture activities using fish traps in the Seribu Islands have relatively high risks as they involve divers, the operation of simple compressors, and dynamic marine environmental conditions. This study aims to analyze the level of risk at each stage of trap fishing, including preparation, fishing operations, and post-fishing activities, as well as to formulate appropriate control measures. The methods applied was Formal Safety Assessment (FSA) to evaluate risks based on frequency and severity. The results showed that most activities were classified as high risk, with 16,7% in the preparation stage, 65,2% in the fishing operation stage, and 61,5% in the post-fishing operation stage, while the remaining activities were categorized as medium risk, and no activities were identified as low risk. Internal factors such as physical fatigue, lack of knowledge, and non-compliance with safety procedures, and external factors such as unfavorable weather and strong underwater currents, were identified as the dominant causes of high risk. Comprehensive risk control is therefore required through regular equipment maintenance, the implementation of safe work procedures, and the consistent use of personal protective equipment to enhance the safety of trap fishers in the Seribu Islands.

UTILIZATION OF BAITED DRIFT FADS ON HANDLINE IN PALABUHANRATU BAY WATERS
type: item
description: Handline fishermen in Palabuhanratu are small-scale fishermen who have limited access to science and technology. This condition has an impact on low catch productivity. Therefore, to overcome this problem, an effective fish collection technology is needed, namely the baited drift fish aggregating device (FAD). This study aims to construct a baited drift fish aggregating device operated by a handline fishing boat as a treatment handline, compare the composition of the catch, determine the effect of using baited drift fish aggregating devices, determine productivity and determine the production margin of the treatment handline catch compared to the control. The experimental fishing method was carried out with 16 trips as replications provided a higher catch result for the treatment handline compared to the control with a total catch of 98.67 kg and 62.34 kg, respectively. Based on the results of the Mann-Whitney analysis, the treatment handline had a significant effect on the number of fish and the weight of the catch. The productivity of the treatment handline had a greater value than the control handline, namely 6.17 kg/trip and 3.90 kg/trip respectively with the production margin of the treatment handline catch compared to the control for weight units and individual increasing by 58.28% and 76.2% respectively.

BAIT BOOSTER UTILIZATION ON BOTTOM GILLNET IN PALABUHANRATU BAY WATERS
type: item
description: The technological status of bottom gillnet fishing gear (rampus net) and its fishing operation methods have not changed much in its development and tend to be static. This problem also occurs among rampus net fishermen in Palabuhanratu Bay, where there is a decrease in catch productivity. The technological innovation needed for rampus net fishing gear is the use of bait boosters to attract and gather fish so that they are easy to catch. The research activities were carried out using an experimental fishing method with 20 trips as replications by comparing between treatment of rampus net with the control. The results showed that there was an increase in catches in treatment of rampus net compared to the control. The catch consisted of 61.2% demersal fish and 38.8% pelagic fish, dominated by largehead hairtail fish. The productivity of the treatment of rampus net had a value greater than the control, namely 0.85 kg/net-piece and 0.50 kg/net-piece, respectively. The production margin of the catch of the rampus net treatment compared to the control was 70.5%. Key words: bait booster, bottom gillnet, Palabuhanratu Bay

EFFECTIVENESS OF RENEWABLE ENERGY LAMPS ON GATHERING FISH IN BAGAN FISHERIES AT BANTEN BAY
type: item
description: The increase in solar fuel (diesel) prices poses major challenge for lift net (bagan) fishermen who rely on generators for their fish-attracting lights. This research investigates the effectiveness of the innovative EBT Lamp (Lacuba) powered by a Seawater Battery as an alternative to solar-fueled generators. The primary objective is to evaluate the performance of Lacuba, focusing on the speed of fish attraction and aggregation, as well as the analysis of community indices (diversity, evenness, and dominance) of the catches. Field trial results indicate that Lacuba is significantly more time-efficient. The average time for fish to be attracted was 6.5 minutes (vs. 12.25 minutes with conventional lamps), and the aggregation time was 60 minutes (vs. 77 minutes). Although both systems showed low community index categories, Lacuba registered lower values for diversity (0.2965), evenness (0.1842), and dominance (0.0392) compared to the conventional fishing lamp.

IDENTIFICATION OF VESSEL ARRIVAL NUMBER AND FISH CATCH AT NUSANTARA FISHING PORT (PPN) IN MERAUKE
type: item
description: One of the efforts in sustainable fisheries management is to measure fishing capacity. Fishing capacity is the maximum number of fish caught by a fishing fleet in a certain period. Currently, Merauke Nusantara Fisheries Port (PPN) is a type B fishing port that functions as a center for fisheries activities, including recording the number of ship arrivals and fish catches. Republic of Indonesia Fisheries Management Area (WPP-RI) 718, which includes the waters of the Arafura Sea, has abundant fish resource potential. However, using these resources must be carried out sustainably to avoid over-exploitation which can harm the fisheries ecosystem and the fishermen's economy. One of the efforts in sustainable fisheries management is to measure fishing capacity. Catching capacity is the maximum number of fish caught by a fishing fleet in a certain period. Currently, there is no comprehensive estimate of fishing capacity in WPP-RI 718, especially in PPN Merauke, which is at risk of not being in line with the Code of Conduct for Responsible Fisheries guidelines. The process of determining fishing capacity begins with identifying fishing activities. This study analyzes the number of vessels, gross tonnage (GT), and the volume of catches landed at the Nusantara Fisheries Port of Merauke Regency. Data was collected through direct observation at the Nusantara Fisheries Port (PPN) and supported by observation, interview, and literature study methods. The respondents targeted in this study were captains or owners of fishing units. The results of the study showed that the number of fishing vessels landing their catches at the Merauke Nusantara Fisheries Port (PPN) in the period from March to May reached 348 units. The vessels consisted of 320 units measuring less than 30 GT and 28 units measuring more than 30 GT. In addition, 22 types of fish were identified with a total catch landed reaching 682.5 tons.

This study aims to design and develop an optimal sailing track for KM Uma 002, a fishing vessel owned by PT Uma Nian Nepa operating in the waters of the Flores Sea. The track design considers environmental factors such as currents, weather, sea depth, and vessel characteristics to enhance travel time efficiency and operational safety. The research methodology used is an applied approach with primary data collection through direct observations of the ship’s sailing route using nautical chart No. 116, interviews with crew members, and navigation analysis. Secondary data were obtained from literature on voyage route planning and the latest navigation technology. The track design includes determining waypoint coordinates, plotting the True Course (HS), calculating the total distance to travel (Distance to Go/DTG), and estimating the time of arrival (ETA). The results indicate that the outer route is safer and more efficient than the inner route, which poses navigation challenges due to narrow waters and numerous coral reefs. Based on the analysis, the journey from the fishing base to the fishing ground at a speed of 6 knots has an estimated travel time of approximately 12.25 hours. With an optimized navigation design, the vessel's operational efficiency is expected to improve while minimizing the risk of maritime accidents. Key words: fishing vessels, KM. Uma 002, navigation, sailing tracks
