Abstract

Floating Solar Photovoltaics (FPV) is the latest innovation in renewable energy that offers great potential to meet global energy needs while reducing environmental impact. In the search for more sustainable and environmentally friendly alternatives to generate electricity, FPV has emerged as an attractive solution. This technology combines two key elements of solar photovoltaic panels and water, by installing solar panels on the surface of water, such as lakes, reservoirs, or even the sea. Floating Solar Photovoltaics not only represents an advancement in photovoltaic technology, but also creates new opportunities to address energy and environmental challenges. In this way, this technology represents an important meeting point between renewable energy and wise management of water resources. In this guide, we will explore the basic principles, benefits, challenges, and potential applications of FPV in the context of an increasingly sustainable global energy economy. Through Floating Solar Photovoltaics, we can maximize the use of abundant sunlight to generate electricity, while preserving water quality and the precious aquatic environment. This approach has the potential to transform the global energy landscape in a sustainable way and reduce our carbon footprint. Let us delve deeper into the concept of FPV and explore how this technology can help us achieve our renewable energy and environmental goals.

Abstract

Sediment movement continuously at the mouth of the river causing erosion and sedimentation and shoreline changes in thearea around the estuary. Introduction behavior sedimentation in the estuary is an important initial step in determining stepefforts to address the problem of sediment deposition and movement. This study aimed to determine the pattern of propagation of waves and currents and their effects on sediment and Tombolo active or cuspate appearance. The methodology used in data collection is to perform direct measurements and the data obtained is processed by software based on finite difference especially for the analysis of wave propagation patterns and sediment movements. The results of the study conducted in the southern estuaries Jeneberang shows that the propagation pattern of waves and currents affect the movement of sediment and the intersection between the two causes that trigger the appearance of sediment deposition on Tombolo active or cuspate.

Abstract

Human life cannot be separated from the use of energy. Energy is needed for many things like cooking, traveling, and working. Currently, electrical energy is the main need. To produce electrical energy, power plants that utilize renewable and non-renewable energy sources are needed. Technology in the field of renewable energy continues to experience rapid development. The use of renewable energy aims to reduce the impact of global climate change and reduce dependence on fossil fuels. A variety of natural resources are available as renewable energy alternatives, one of which is marine power technology. Marine energy technology is a technology that utilizes various properties and movements of the ocean to generate electrical energy. Energy sources from the sea can be utilized by using marine technology such as ocean current technology, ocean wave technology, and ocean thermal energy conversion. This technology makes it easy to adapt to the characteristics of the exploited sea.

Abstract

Ship engines are machines that play an important role in the dynamics of the fishing business. Unfortunately, traditional fishing boat engines in Indonesia are neglected in maintenance and repair, so that apart from affordable areas, efforts in unreached areas are very important. In this research, damaged machines are maintained and repaired, working hours are monitored, with the main aim of evaluating continued seaworthiness compared to machines that work continuously. Machine operation, machine working hours, assessed for one year in Tablolong village, East Nusa Tenggara, Indonesia. The effective day rate of operation ranges from 268±97 to 275±90 idle time in machine operation and from 190±175 to 200±165 idle time in continuous machine operation. Machines that are maintained every month have higher levels of operation and movement compared to machines that are maintained for three and five months. However, the seaworthiness of the engines is very low, mostly due to lack of understanding, unavailability of engine maintenance facilities. Effective days in machine operation were observed, during the period (January-November). Machine maintenance is very useful for traditional fishermen who lack skills. Nevertheless, ongoing long-term and systematic monitoring is necessary to have a greater understanding of maintenance and repair.

Abstract

Cold storage is an important facility in the fishing industry to extend the shelf life of products, especially frozen fish, while maintaining their quality. This research analyzes the performance of the Elitech RC4 HC Data Logger in monitoring temperature and humidity in a 400-ton capacity cold storage at PT Delta Mina Perkasa, Sidoarjo, East Java. Research methods include surveys, direct observation, interviews, and internships, with descriptive and quantitative data analysis approaches. Data loggers were placed at three points: near the door, the middle section with load, and the back section without load, to record temperature and humidity conditions for 78 days. The results showed that the best temperature and humidity stability was recorded in the center of the cold storage, while the largest temperature fluctuations occurred near the door, caused by door opening and closing activities. In June, the cold storage conditions were considered good, but the quality of frozen fish decreased during July to September due to machine repairs. Overall, the Elitech RC4 HC Data Logger proved effective in monitoring real-time temperature and humidity conditions. However, to maintain the quality of frozen fish consistently, it is recommended that the company adds specialized humidity monitors, improves cold storage management, and conducts regular monitoring.

Abstract

This study aims to analyze the relationship between stress coping and cadets’ learning motivation in Vocational Maritime Education and to formulate relevant policies. The study population consisted of 95 first-year cadets’ at the Vocational Faculty of Maritime. The sampling technique used was saturated sampling, where all 95 cadets’ became research participants. Data collection methods included questionnaires, observations, and interviews. Data analysis was conducted using multiple regression analysis, with hypothesis testing performed using t-tests and F-tests. The results showed that Emotion-Focused Coping did not significantly affect learning motivation when analyzed separately. However, Problem-Focused Coping had a significant impact on learning motivation. When considered simultaneously, both coping strategies significantly influenced cadets’' learning motivation. Based on these findings, this study suggests the necessity of a comprehensive policy to help cadets’ manage stress. This includes providing guidance and counseling services and developing effective stress management training programs to enhance cadets’ well-being, reduce dropout rates, and increase learning motivation. Implementing these policies is expected to support cadets’ in achieving optimal academic performance and completing their education on time.
