Abstract

This study investigates the application of renewable energy—specifically solar panels and wind turbines—in the electrical systems of fishing vessels. The research methodology includes literature review, power demand analysis, simulations, and experimental trials on a prototype fishing vessel. The findings demonstrate that integrating renewable energy systems can reduce fuel consumption by up to 30% and significantly improve operational efficiency. The adoption of a hybrid solar and wind energy system enables fishing vessels to remain at sea longer without complete reliance on fossil fuels. This study makes a notable contribution to the field of marine electrical systems and renewable energy by developing and validating a sustainable, energy-efficient onboard power system through a comprehensive empirical approach—ranging from technical design and simulation to field implementation. Key outcomes include a 30% reduction in fuel use and an increase in system efficiency to 85%, offering a practical solution for lowering operational costs among small-scale fishermen. The research also advances theoretical understanding of renewable energy integration in the maritime sector, which has predominantly focused on large commercial vessels. The incorporation of lithium-ion–based energy storage systems in small Indonesian fishing vessels presents a novel approach with significant development potential, particularly in addressing geographic and energy access challenges in remote coastal communities. These results provide a foundation for formulating government policies on subsidies and incentives to support the transition to green energy in the national fisheries sector.

Abstract

Internet of Things (IoT)-based monitoring systems are increasingly being adopted across various sectors, including aquaculture. Shrimp farming, in particular, relies on a stable energy supply to operate aeration and water circulation systems. Solar panels offer an efficient renewable energy solution; however, their optimal performance requires continuous and reliable monitoring. This study aims to design and implement an IoT-based monitoring system to track solar panel performance in shrimp farms, thereby enhancing energy utilization efficiency. The system integrates sensors for current, voltage, temperature, and light intensity with a microcontroller and an IoT platform for real-time data acquisition and analysis. The test results demonstrate that the system effectively provides accurate and timely information on solar panel performance, enabling early detection of efficiency losses and prompt maintenance actions. The implementation of this system is expected to increase energy resilience and operational efficiency in shrimp farming operations. By combining IoT technology with renewable energy monitoring, this research offers a practical and scalable solution tailored for remote aquaculture environments. Additionally, the study highlights the feasibility of using low-cost hardware and open-source platforms, making the system accessible for broader application, particularly in developing regions. This contribution supports the advancement of sustainable and energy-efficient aquaculture practices through innovative, technology-driven approaches.

Abstract

AutoCAD is a vital computer-aided design (CAD) tool widely used in civil engineering, architecture, and manufacturing. Mastery of AutoCAD programming significantly enhances the industrial competitiveness of vocational high school (SMK) graduates. This study aims to implement AutoCAD programming training for students at SMK PGRI 4 Surabaya to improve their technical competence and efficiency in using AutoCAD. Employing a project-based learning model, the research evaluated student outcomes through pre- and post-tests. The results indicate a 45% improvement in students’ technical proficiency, particularly in automating repetitive tasks and developing structured design templates using AutoLISP and VBA. The training also enhanced students' ability to create complex technical models and improved their overall design efficiency and problem-solving skills. In addition to technical gains, the training fostered the development of essential soft skills, including teamwork, communication, and creativity, through collaborative, real-world design projects. These findings highlight the effectiveness of integrating AutoCAD programming into vocational curricula to better align with industry needs. Key contributions of this study include: the application of a structured, project-based training model combining CAD and automation programming; empirical evidence of AutoCAD programming’s impact on student readiness for engineering and manufacturing careers; and the dual emphasis on technical and soft skill development, an area often underrepresented in prior research. The study offers practical recommendations for vocational schools to embed programming into CAD instruction, ensuring graduates possess industry-relevant competencies aligned with Industry 4.0 demands
