Abstract

Fish is a food source rich in nutritional value, yet highly perishable and susceptible to rapid quality deterioration. The aim of this research was to evaluate the implementation of GMP and SSOP in the processing of sandwich yellowfin sole products, and the basic feasibility of the fish processing unit at PT Bumi Menara Internusa Surabaya. This study used qualitative descriptive method through a gap analysis of the application of GMP, SSOP, and basic feasibility. The results showed that, according to the Ministry of Maritime Affairs and Fisheries Regulation Number 17 of 2019, the implementation of GMP and SSOP has been carried out effectively and met the required standards for basic feasibility, with no critical, serious, minor, or major findings, earning the Excellent (A) rating. The production process of frozen sandwich yellowfin sole at PT Bumi Menara Internusa Surabaya includes raw material receiving, thawing, weighing 1, washing 1, skinning, filleting, V cutting, trimming, bone and parasite control, washing 2, joining married portion, layering, IQF freezing, sorting and sizing, weighing 2, glazing, metal detecting, polybag packaging, MC packaging, weighing 3, frozen storage, and stuffing, all of which have effectively implemented the cold chain system, as demonstrated by the temperature observation table for the products, room, and water (good cold chain). The yield obtained after the skinning process of yellowfin sole was 90%.

Abstract

This study aims to analyze the cost and revenue structure and evaluate the financial feasibility of the tilapia (Oreochromis niloticus) seed production (hatchery) business. The breeding stage is a crucial early phase in the aquaculture production cycle. The feasibility evaluation encompassed calculations of the Revenue to Cost Ratio (R/C), Break-Even Point (BEP), and Return on Investment (ROI). The method employed was a profitability analysis using revenue theory, applying the R/C, BEP, and ROI formulas to the business's cost and revenue data. The results indicate that from a technical and technological perspective, all operational requirements for the hatchery were met, including location suitability, operational scale, pond management, and resource utilization, supported by a single-level distribution system. Economically, the business showed profitability and business viability. The total revenue reached IDR 79,552,083. The financial analysis yielded an R/C ratio of 1.5, signifying that every Rp1 spent generated IDR 1.5 in revenue. The production break-even point (BEP) was achieved at 12,635,416 fish seeds. It is concluded that the tilapia seed production business is comprehensively feasible and profitable for further development.

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

Mangrove forests are types of vegetation that grow under the influence of the rising and falling sea water. They play a crucial role ecologically, physically, and economically. However, without proper management, this ecosystem is at risk of harm. In Segarajaya Village, Tarumajaya District, Bekasi Regency, West Java, mangrove forests are threatened by human activities, such as clearing land for fish farming without preserving mangrove vegetation, along with pollution from plastic and household waste. This study aimed to assess the health of mangroves based on two aspects: (1) MHI parameters, which include canopy cover, individual density, and stem diameter; and (2) environmental parameters, which consist of salinity, water and air temperature, soil pH, and substrate type. The method employed is the Mangrove Health Index (MHI), which involves calculating the parameters of canopy cover, stake density, and average stem diameter at breast height, along with environmental parameters (salinity, water and air temperature, soil pH, and substrate) conducted from February 25 to April 20, 2025. The observation site was divided into three stations. Station 1 had the species Rhizophora apiculata, Avicennia marina, and Sonneratia caseolaris. Station 2 was populated with Bruguiera gymnorhiza and Sonneratia caseolaris, while Station 3 only contained Avicennia marina. The MHI value calculations indicated that the mangrove forest's condition falls into the moderate category, with an average MHI value of 61.78%. Station 1 recorded 62.69%, Station 2 61.63%, and Station 3 61.02%. The average values of environmental parameters were a salinity of 30.44‰, water temperature of 27.94°C, air temperature of 30.89°C, soil pH of 7.33, and substrates consisting of sandy clay and mud. This study aims to inform readers about the health conditions of mangroves and serve as a foundation for managing and protecting mangrove forests.
