Abstract

Coral fish are organisms with the largest amount of biomass and are also large organisms that can be found in coral reef ecosystems. The tendency of coral fish is that they do not move around and are always in a certain area and are very relocated although still many (Nybakken, 1988). The coral fish that are often found on the island of Lancang is the Tiger Grouper fish (Epinepheus fuscoguttatus). Grouper fish have a high economic value if fishermen do good cultivation on this Lancang island. The method used was mobile and controlled hydroacoustics, located in Pulu Lancang Thousand Islands. The instruments used are SIMRAD EK 15. The number of samples measured as many as 3 heads with a total length ranging from 21,70 cm to 42,50 cm and has the total weight of the three fish of 186,9 gr to 640 gr with a recording time of 5 minutes was done at the Dock and Floating Net Cage. The sounding results of tiger grouper were then analyzed using Echoview 4.0 and microsoft excel. The results of the analysis showed the average TS value in 3 tiger groupers whose total length ranged from -34,77 dB to -32,37 dB and the longer the total length of the fish, the greater the TS value.

Abstract

Purse seine fishing gear has advantages in the efficiency of catching large quantities of pelagic fish and is considered environmentally friendly because it does not damage the seabed. Handling fish catches from purse seine fishing gear at the Sadeng Coastal Fisheries Port (PPP), there are two types, namely by using salt and ice which can maintain freshness and increase the selling price. This shows that the feasibility of purse seine using ice and salt can improve community welfare and is feasible to be developed. The purpose of this study is to analyze operational activities (construction, fishing gear operating techniques, area and season of operation, size of vessels and engines) and the feasibility of purse seine fishing gear at the Sadeng Beach Fishing Port. The research was carried out by descriptive method, sampling by purposive sampling. The analysis was carried out by explaining the operation activities of the purse seine ship from preparation, determination of fishing areas, travel, the process of capture, transportation and management of catches on board, and landing. The 35 GT purse seine catching unit has a lower fixed cost because the depreciation costs and licensing fees that must be incurred are lower than the 45 GT purse seine fishing unit. Based on calculations, an average R/C value of 1.3121 was obtained. This indicates that the R/C value > 1, which means that the venture is profitable and worth developing.Keywords: Feasibility, Fishing Gear, Purse Seine,  Sadeng Beach Fishing Port

Abstract

Sound speed in the ocean is a key parameter for underwater acoustic applications, such as communication, navigation, and sonar systems. Sound speed is influenced by temperature, salinity, and pressure, making it highly sensitive to seasonal oceanographic dynamics. Although the Banda Sea is recognized as one of the strongest upwelling centers in Indonesia, studies specifically addressing the seasonal variability of sound speed profiles in this region remain limited. This study aims to analyze the differences in temperature, salinity, and sound speed characteristics between the west and east monsoon periods in the Banda Sea. Monthly temperature and salinity data for 2023 from the Copernicus Marine Environment Monitoring Service (CMEMS) with a spatial resolution of 0.083° × 0.083° were processed using Ocean Data View (ODV). Sound speed was analyzed in terms of its horizontal and vertical distributions at depths of 0, 150, and 300 m, as well as vertical profiles down to 500 m. During the west monsoon (January), surface temperature was higher (29.5–31 °C) and sound speed reached maximum values (1543–1546 m/s), with a deeper thermocline due to downwelling. In contrast, during the east monsoon (July), surface temperature was lower (26.5–28.5 °C), the halocline was shallower (34.7–35.2 PSU at 50–150 m), and surface sound speed decreased (1538–1541 m/s), reflecting seasonal upwelling. Minimum sound speed was consistently observed at 300–500 m (1496–1505 m/s). These findings highlight temperature as the dominant factor controlling sound speed, with important implications for the planning of underwater acoustic operations in eastern Indonesian waters.

Abstract

The increasing demand for natural and environmentally sustainable cosmetic products has stimulated interest in utilizing mangrove-derived bioactive compounds as alternative ingredients in lip balm formulations. Mangrove species are recognized as rich sources of secondary metabolites, including flavonoids, polyphenols, tannins, terpenoids, and natural lipids, which exhibit antioxidant and protective properties beneficial for lip care applications. This study aimed to systematically evaluate the potential of mangrove species as active ingredients in lip balm formulations by examining their phytochemical characteristics, antioxidant activities, and formulation performance. A Systematic Literature Review approach was employed following the PRISMA framework, involving the collection, screening, and synthesis of relevant studies published between 2020 and 2025. Eighteen eligible primary research articles were included in the final analysis. The results demonstrated that Sonneratia alba, Bruguiera gymnorrhiza, Ceriops tagal, Rhizophora mucronata, and Avicennia marina possess diverse bioactive compounds and promising antioxidant activities, with several species exhibiting very strong antioxidant capacity based on IC₅₀ values. Furthermore, lip balm formulations containing mangrove extracts generally fulfilled cosmetic quality requirements, including appropriate pH, good homogeneity, acceptable melting points, physical stability, and non-irritating properties. These findings highlight the potential of mangrove extracts as multifunctional natural ingredients for developing safe, effective, and sustainable lip balm products, while supporting the value-added utilization of coastal biological resources and promoting future innovation in natural cosmetic formulations.

Abstract

The development of an automatic hydroponic system in the Senggarang area, Tanjungpinang began with regional observation and interviews at the Senggarang Village Office to identify existing problems and potentials. The purpose of developing hydroponic plants with automatic water fillers is to reduce public expenditure on buying food, especially vegetable ingredients, and minimize places to grow crops. The method used in the development of hydroponic plants with automatic water filling uses a descriptive method. The implementation of an automatic water filling system using Arduino Uno, relays, water pumps, and ultrasonic sensors has shown satisfactory results. The system works consistently by turning off the pump when the water level reaches 2-3 cm and turning it back on when the water level drops to 11 cm. The test results showed a stable reading with the pump off at a distance of 2.07 cm and on at a range of 11.17-11.63 cm prove that the system can work effectively without manual supervision.

Abstract

Marine fishery resources contribute to food needs, especially for local communities. The Riau Islands is one of the provinces with abundant marine products but only has 1 fishing port, which can trigger an increase in fish prices in the market and for consumers because the costs incurred by ship owners are getting higher. In addition, it will also cause a decrease in the quality of fish or fish that are not fresh because of the long production chain, which takes a lot of time. Currently, identification of fish freshness is still done manually by fishermen, traders, and consumers. This will certainly make it a little difficult to distinguish between fresh fish and fish that are no longer fresh. One way to recognize and identify fish freshness in the field of informatics is to use image processing. This study will create an image processing system to identify fish freshness using the hue saturation value (HSV) and k-nearest neighbor (K-NN) methods. Based on the results of testing marine fish images, namely mackerel and tuna, which were carried out using the HSV and K-NN methods, it was found that the identification of the quality of freshness of marine fish using the Hue, Saturation, and Value (HSV) color feature extraction was successfully applied with an accuracy value of 100% for the test image of mackerel and 95% for the test image of tuna.
