Abstract

This study aims to obtain an effective solar panel tracking mechanism using energy-efficient electric actuators. Furthermore, we designed and implemented a semi-active solar tracking system. A tracking system is proposed to control solar panel orientation using a moving mass, a spring system, and an actuator. The weight of the moving mass and the spring constant are optimized to reduce actuator size. A stepper motor was used for this case. This electric drive is not the primary mover of the solar tracker; hence, it works against mass elements lighter than solar panel weight as used in the active solar tracker. Experimental results suggest that the average power required by the stepper motor is 0.21% of the energy generated by the solar tracking system.

Abstract

Mini hydro power plants (PLTM) are capable of producing electricity continuously for 24 hours. The amount of energy distributed by the Mini Hydro Power Plant (PLTM) is greatly influenced by the strong flow of water coming from upstream, so the effect of rainfall is relatively direct on the electricity produced by the Karo Bumi Energi Mini Hydro Power Plant (PLTM) with a capacity of 2 x 4, 85 MW. From the observations, rainfall is a dry month, it can also be seen that rainfall, water discharge and production are directly proportional. In May, June and July there is a very significant difference between production and water discharge. According to observations, these months are wet months with very high rainfall. The resulting productivity of hydropower plants is influenced by the creation and release of stable water without aggravation. The higher the creation and release of water, the higher the efficiency of the power supplied. The impact of high rainfall will cause the water release to reach 11,653m3 / hour

Abstract

The Salvonius wind turbine is one of the Vertical Axis Wind Turbines (VALWT) commonly used in wind farms. This type of turbine is usually used for medium and low wind speeds. It has a simple design, consisting of a single main rotor that rotates vertically. The advantage is that it can use wind from all directions, can work at low speeds and does not require a tower that is too high. The aim of this study was to analyse the performance of the turbine in relation to the rotation and power of the land generator. The method used was to directly measure the rotation of the turbine and the generator in no-load and load conditions. The results of the study showed that the average wind speed in Oenalli village was 4.66 m/s, and this turbine was able to rotate the Salvonius turbine with an average rotation of 631 rpm. It was then able to produce an output of 7.20 MW at a general turbine speed of 1,243 rpm. In addition, the average generator efficiency was 35%, the highest daily efficiency was 39% and the lowest daily efficiency was 37%.

Abstract

The integration of computer-based simulations in electrical engineering education enhances students' understanding of complex concepts such as Geometric Mean Radius (GMR) and Geometric Mean Distance (GMD) in transmission line systems. This study aimed to develop and evaluate a MATLAB-based simulation tool to support learning in voltage regulation and efficiency analysis. Adopting a Research and Development (RD) methodology guided by the ADDIE model, the simulation was tested with 32 electrical engineering students. Expert validation, conducted by three power systems professors and two instructional technology specialists, confirmed high content validity (average score 85%). Data analysis using SmartPLS revealed that simulation quality significantly influenced both conceptual understanding (β = 0.903) and learning effectiveness (β = 0.977), with strong model fit (R² = 0.846). Students’ comprehension of voltage regulation and efficiency improved significantly, as indicated by N-gain scores of 0.75 and 0.72, respectively, while parameter analysis proficiency rose from 42.8% to 80.7%. These findings suggest that the simulation tool not only enhances academic learning but also offers industrial benefits. Specifically, it provides power utilities with a cost-effective means to optimize transmission line designs, reducing iteration costs by up to 60%. It also enables rapid prototyping of conductor configurations and serves as a standardized platform for professional training. Furthermore, the tool supports sustainable energy efforts by improving the integration of renewable energy sources through optimized line parameter analysis.

Abstract

This research examines the integration of the concept of electrical conductivity in the Measurement and Instrumentation course through a soil fertility monitoring tool. Using a mixed methods approach, the study involved 30 third-year Electrical Engineering students who engaged with a specially designed soil monitoring system as a learning medium and practicum tool. Quantitative analysis showed a significant increase in student understanding, with the mean test score increasing from 42.3 (SD = 8.7) in the pre-test to 78.5 (SD = 9.5) in the post-test (p 0.001, η² = 0.61). Practical skills assessment showed that 83% of students achieved proficiency in tool calibration, while 90% successfully integrated electrical conductivity data with other parameters. Qualitative findings showed an increase in student engagement, with 92% reporting an increase in learning motivation. This implementation resulted in three main outcomes: improved theoretical understanding through hands-on experience, improved technical measurement skills, and the development of an interdisciplinary perspective linking engineering to agricultural applications. The findings suggest that integrating real-world applications into engineering education can significantly improve technical competence and practical skills, providing a model for curriculum development in other engineering disciplines. This study offers valuable insights for engineering educators who want to bridge the gap between theoretical knowledge and practical applications in measurement and instrumentation courses.
