Abstract

This research aims to explore the advantages and challenges of the Project Based Learning (PJBL) learning model in developing higher-order thinking skills among students. This research uses the Systematic Literature Review (SLR) method. This research analyzes search results originating from the Scopus, Erics, and Google Scholar databases, spanning the last 10 years. The limitation of this research is that the articles used consist of a period of 10 years. It is hoped that in future research the data can be further improved. Based on the article data that was searched, 10 articles were taken which were used as study material. The results of the analysis of the review of this article can draw conclusions and findings that the learning model (PjBL) has the following advantages: 1) can increase student motivation and involvement in the learning process, 2) develop real skills, 3) increase learning outcomes and collaboration and communication skills, critical thinking, and creative thinking; 4) active and student-centered learning. Meanwhile, the weaknesses of the Project Learning Model (PJBL) are: 1) implementing PjBL the teacher must prepare a project that will be used in learning so it requires a lot of time; 2) This PjBL requires complete facilities to be implemented well so several schools have limited resources; 3) in implementing PjBL, it is difficult to involve all students in group work because not all students are active; 4) the costs of implementing PjBL require a lot of money so the use of this PjBL learning model needs to be considered.

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.

Abstract

The research examines the design of a simulation program for short circuit calculations. A short circuit is an abnormal event called a disturbance in the electric power system. The classification of short circuit consists of three-phase fault, single-phase fault to ground, two-phase fault and two-phase fault to ground. Calculation of short circuit faults in electric power systems is very important for the study of reliability and safety of power systems. The method used in the design of the Graphical User Interface (GUI) based simulation program is the experimental method, which is to identify the magnitude of the short circuit current value based on the theorem of Fortescue's theorem related to symmetrical components. Furthermore, a GUI program script is built for short circuit calculations. The GUI success test was carried out by comparing the results of the short circuit analysis with the short circuit calculation program using Matlab and validation by experts. From the results of testing and validation by experts, it can be seen that the program built can complete the calculation of short circuit faults validly. The GUI SCC program can be applied to electric power system analysis learning, with a media validity level of 0.85, which is good for use in learning. In addition, this study also built a simulation for the calculation of class intervals and the practicality of the media using the Simulink Matlab media, the results of the program design were declared by experts to be valid with an average score of 0.8625

Abstract

Fossil fuel power plants are still used as a source of energy around the world and have a significant impact on emissions and environmental pollution. To reduce these emissions, renewable energy offers a solution that can be applied in future housing. This study proposes a simulation using HOMER to determine the most cost-effective composition of hybrid renewable energy systems in housing. This simulation can combine photovoltaic (PV) systems, wind power (WP), and a converter that functions to change DC to AC from PV to obtain an alternating current (AC) system. The hybrid combination of PV and WP proves to be the most appropriate and economical choice at the research location. The results of the study showed that the installation of a hybrid system in housing, with an initial investment cost of IDR 107,474.43 million and an annual operating cost of IDR 22,540.23 million, is 41% lower than conventional fossil fuel-based systems. Research data shows that the project's payback period is estimated to be around 11 years. These findings can be recommendations for similar systems in regions with similar contours and geography. Apart from that, positive monetary impacts can provide incentives for policymakers to implement similar hybrid systems, thereby contributing to the goal of global emissions neutralization.
