Abstract

Pekalongan National Fishing Port (PPN Pekalongan), a type B fishing port, is recognized for its well-managed facilities and serves as an operational base for purse seine vessels. Purse seines are widely employed to harvest schooling pelagic fish, most of which are species of high economic value, thus requiring appropriate handling to maintain quality. This study aims to examine the handling practices of purse seine catches on board KM. Bintang Mas Maritim, focusing on storage temperature, handling equipment, and storage duration under freezer-based systems. Data collected included fish temperature at hauling, during freezing, and after storage, as well as the handling methods and equipment used by fishermen. The initial body temperature of the fish was 29.3°C at hauling. Fish were sorted by species, size, and quality, then washed and frozen at -18°C for 24 hours. Once frozen, they were packaged and transferred to the fish hold at -13.7°C for storage. The findings highlight the importance of systematic handling, washing, rapid freezing, and controlled storage—to maintain fish quality and extend shelf life.

Abstract

The Togean Islands, located in Tomini Bay, Central Sulawesi, Indonesia, are part of the coral triangle that encompasses the waters of Indonesia, the Philippines, Malaysia, Papua New Guinea, Japan, and Australia. This region hosts a coral reef ecosystem that relies on ocean currents for nutrient distribution and coral larval dispersal. Maintaining the balance and health of ocean currents is crucial for the sustainability of this ecosystem. This study aims to map ocean current patterns in the waters of the Togean Islands during the 2021–2022 period using data from Copernicus Marine. A secondary data analysis with a descriptive approach was employed. Data were obtained from the Copernicus Marine platform and processed using SeaDAS and ArcGIS software. In 2021, the recorded current speed was relatively lower, ranging from 0.04 m/s to 0.16 m/s, whereas in 2022, the current movement was stronger, with an average speed ranging from 0.06 m/s to 0.21 m/s. The comparison of ocean currents in the Togean Islands showed peak values in December for both years, while the lowest average speeds were recorded in March 2021 and October 2022. These current patterns are influenced by seasonal factors and play a significant role in marine ecosystem dynamics. This mapping is expected to serve as a reference for the management and conservation of coral reefs in the Togean Islands.

Abstract

Marine spatial management in coastal areas faces increasing challenges related to conflicts over space utilization and zoning violations that are often not detected at an early stage. This study aims to analyze the effectiveness of participatory marine spatial audits as an instrument for the early detection of conflicts and zoning violations, as well as to derive policy lessons from their implementation in Bekasi Regency. The study employs a participatory qualitative approach involving pentahelix stakeholders, including academia, government, the private sector, media, and coastal communities. The audit process was conducted through a collective assessment based on three main criteria: (i) conflict and risk, (ii) legality and compliance, and (iii) the suitability of the social-ecological system.  The audit results show an aggregate score of 3.08, categorized as “moderately compliant/requiring capacity building,” indicating that marine space utilization is relatively controlled but still requires strengthened governance. The participatory marine spatial audit proved effective in revealing latent conflicts, gaps between regulations and actual practices, and the influence of socio-economic factors on zoning compliance. Respondent characteristics, such as institutional background, age, education level, household size, and income level, were found to influence perceptions and audit assessment outcomes.  This study concludes that participatory marine spatial audits function not only as a technical evaluation tool but also as a mechanism for social learning and policy capacity building. Integrating marine spatial audits into local policy cycles has the potential to enhance early conflict detection, improve zoning compliance, and support sustainable and equitable marine spatial management.

Abstract

Coastal areas play a crucial role in supporting tourism, local economies, and the conservation of natural resources; therefore, sustainable management based on suitability and environmental carrying capacity data is essential. This study aims to analyze the level of suitability and carrying capacity of the coastal tourism area at Allang Asaude Beach, Huamual Belakang District, West Seram Regency, Maluku Province. Data was collected through direct observation and open-ended interviews. The assessment of coastal tourism suitability employed ten parameters, including beach type, beach width, substrate material, water depth, clarity, current velocity, beach slope, land cover, presence of hazardous biota, and availability of freshwater. The results showed that the coastal tourism suitability index at three observation stations fell into the highly suitable category, with an Index of Tourism Suitability (ITS) value of 2.99. The supporting biophysical conditions such as clear waters, calm currents, and white sandy beaches were the main determinants of this classification. Meanwhile, the Carrying Capacity (CC) calculation indicated that the Allang Asaude coastal tourism area could accommodate up to 1,363 visitors per day, remaining within the safe ecological threshold. These findings suggest that Allang Asaude Beach has excellent potential to be developed as a sustainable marine tourism destination, provided that environmental management, conservation principles, and local community participation are effectively implemented.

Abstract

Lulur berbahan dasar buah Xylocarpus granatum berpotensi dikembangkan sebagai produk kosmetik alami karena mengandung senyawa bioaktif yang bermanfaat bagi kulit. Namun, mutu fisikokimia lulur sangat dipengaruhi oleh metode pengeringan yang digunakan. Penelitian ini bertujuan untuk membandingkan karakteristik fisikokimia lulur buah X. granatum yang dikeringkan dengan metode sinar matahari dan oven. Penelitian dilakukan melalui tahapan pembuatan simplisia, pengolahan menjadi serbuk, serta formulasi lulur. Parameter uji meliputi rendemen, pH, kadar air, dan viskositas. Rendemen dihitung dengan perbandingan bobot serbuk terhadap bahan segar, pH diukur menggunakan pH meter, kadar air ditentukan dengan metode oven, sedangkan viskositas diuji menggunakan Brookfield Viscometer sesuai SNI 06-6989.23-2005 dan ASTM D2196-20. Hasil penelitian menunjukkan bahwa pengeringan oven menghasilkan rendemen lebih tinggi (28,4 ± 0,05%) dibandingkan pengeringan sinar matahari (6,13 ± 0,28%). Nilai pH keduanya masih sesuai dengan kisaran pH kulit, yaitu 6,53 ± 0,05 (oven) dan 6,13 ± 0,28 (sinar matahari). Kadar air lulur sinar matahari lebih rendah (9,34 ± 0,43%) dibanding oven (11,66 ± 0,38%), sedangkan viskositas lulur sinar matahari lebih tinggi (11.833,33 ± 763,76 cP) daripada oven (9.833,33 ± 152,75 cP). Dapat disimpulkan bahwa metode pengeringan memengaruhi mutu fisik lulur mangrove. Pengeringan oven lebih efisien dalam meningkatkan rendemen dan kestabilan pH, sedangkan pengeringan sinar matahari menghasilkan kadar air lebih rendah dan viskositas lebih tinggi sehingga memberikan tekstur lebih kental. Hasil ini menunjukkan bahwa pemilihan metode pengeringan perlu disesuaikan dengan tujuan formulasi produk lulur.

Abstract

This study aims to determine the type and composition of the catch, as well as describe the operation of the sondong fishing gear (push net) in the waters of the Rupat Strait, Dumai City, Riau Province. The method used is a descriptive method with quantitative and qualitative approaches. Data collection was carried out through direct observation, interviews with fishermen from KM Camar Laut, and documentation of catches from January to June 2025. The results of the study indicate that the sondong fishing gear has a simple construction with high effectiveness in catching white shrimp (Penaeus sp) as the main catch. In addition, there are bycatch in the form of senangin fish, gulama fish, sole fish, flatfish, black pomfret, swimming crab, sea eel, and tiger shrimp. The discarded catch that has no economic value is dominated by puffer fish (Tetraodon sp). Of the total catch of ±2,437 kg, approximately 43.4% is the main catch, 25.2% is bycatch, and 31.4% is discarded. Although effective, this tool is considered less selective and has the potential to damage the waters bottom. Therefore, sustainable management and monitoring of the use of sondong fishing gear is needed so as not to threaten the sustainability of the marine ecosystem in the area.

Abstract

Fisheries activities at the Bitung Ocean Fishing Port (PPS) have the potential to cause pollution, particularly due to waste generated by fishing vessels. Waste generated on board is categorized into two types: organic and inorganic waste. Information on waste management aboard fishing vessels based at PPS Bitung is minimal and very limited. The aims is to study waste management aboard these vessels and analyze waste management strategies. The research was conducted from August to November 2024 at PPS Bitung. Data were collected using survey methods and interviews with respondents selected through purposive sampling. Data were collected using survey methods and interviews with respondents selected by purposive sampling. Data analysis used descriptive methods with a qualitative approach, and waste management strategies were analysed using SWOT analysis. The results showed that the categories of waste generated by fishing vessels include wet waste (food), which is directly dumped into the sea, and dry waste such as plastic, bottles, cloth, glass, and metal, which are collected first. Dry waste management is carried out in two ways, namely without sorting and with sorting. The waste management strategy on board fishing vessels in PPS Bitung is designed to increase environmental awareness and waste management efficiency through an integrated approach. The combination of education, regulation and partnership provides a comprehensive solution to minimize the environmental impact of waste and increase the active participation of crew members in waste management. Consistent implementation of this strategy can serve as a model for sustainable waste management in the fisheries sector.

Abstract

The waters of Dumai City, located in Riau Province and directly connected to the Malacca Strait, are highly accessible both locally and internationally. The coastal area is characterized by intensive human settlements and diverse industrial activities, including oil and gas, crude palm oil (CPO), and cement industries, which discharge wastes that may affect marine biota. Most of these wastes are transported to the sea through river flows, posing a serious threat to the ecological balance and aquatic organisms, particularly fish, with potential risks to human consumers. This study aimed to examine the physicochemical parameters of the waters and to determine the concentration and status of cadmium (Cd) and lead (Pb) in water, sediment, and fish. The research was conducted from April to June 2025 using survey, observation, and experimental methods in both field and laboratory settings. Data were analyzed using Atomic Absorption Spectrophotometry (AAS) to measure the actual concentrations of heavy metals. The results were compared with the threshold values established by the Indonesian Ministry of Environment Decree No. 51/2004 concerning marine water quality standards for aquatic biota. The findings revealed that the physicochemical parameters, including water temperature, salinity, and dissolved oxygen (DO), remain supportive of aquatic life according to the standards. However, the concentrations of Pb and Cd in water, sediment, and fish samples exceeded the permissible limits, indicating pollution in Dumai waters.

Abstract

Bigeye tuna is one of Indonesia's leading fishery commodities. One of the main locations for the routine landing and handling of this species is the Cilacap Fishing Port. The selling price of bigeye tuna plays a crucial role in the sustainability of fisheries businesses. However, unstable and unpredictable tuna prices make it difficult for some businesses to assess their long-term sustainability. Various factors influence tuna prices, both internal to fishing operations and external economic conditions. This study aims to identify factors that influence the selling price of bigeye tuna at the Cilacap Fishing Port. This study used direct observation, interviews, and a literature review, with data ranging from 2022 to 2024. The analytical approach used was multiple linear regression analysis. The research findings indicate that the selling price of frozen bigeye tuna is influenced by production volume, production value, fishing month, and operational costs. The F-test results indicate that the dollar exchange rate, export volume and value, production volume, production value, fishing month, and operational costs simultaneously influence the selling price of bigeye tuna. These variables influence 80.6% of the selling price of bigeye tuna, while 19.4% is influenced by other factors outside the research.
