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.

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

The rapid advancement of Information and Communication Technology (ICT) has significantly transformed educational practices by introducing innovative and interactive learning tools. One such technology is Augmented Reality (AR), which merges real-world environments with virtual elements in real-time, providing immersive and engaging educational experiences. This community service activity aimed to enhance digital literacy among teachers and students at SMKN 5 Tanjungpinang through the introduction and practical demonstration of AR as an interactive learning medium. The implementation involved presenting the basic concepts of AR, hands-on demonstrations using mobile-based AR applications featuring realistic 3D models of ships, and simulations of maritime conditions using AR models. These simulations allowed participants to explore vessel scenarios and behaviors in various sea conditions, thus bridging theoretical concepts with practical visualization. Evaluative feedback, gathered through interviews and direct observations, indicated that the AR sessions significantly improved participants' understanding of complex visual-spatial concepts inherent in maritime education. Participants also expressed high enthusiasm, suggesting strong acceptance and potential for broader integration of AR technologies in vocational education. This initiative underscores the importance of interactive and simulation-based technologies in education, particularly in technical fields requiring detailed visualization and practical comprehension.

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.
