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

Potensi limbah pertanian dan perkebunan dilingkungan sekitar desa sangat melimpah dan berpotensi dimanfaatkan sebagai sumber pakan ternak alternatif. Potensi ini belum dimanfaatkan secara optimal oleh peternak dikarenakan keterbatasan teknologi dan pengetahuan. Program Kemitraan Masyarakat (PKM) bertujuan meningkatkan kemandirian  Peternak Plamboyan di Desa Huta 1 Nagori Partimbalan, Kecamatan Bandar Masilam, Simalungun dalam pengolahan pakan bersumber dari limbah pertanian yang dapat diolah dalam bentuk pakan hijau dan fermentasi. Metode PKM menggunakan pendekatan partisipatif yang meliputi observasi lapangan, focus group discussion (FGD), persiapan teknologi, pelatihan teknis, demonstrasi, pendampingan implementasi, penguatan manajemen usaha sederhana, serta monitoring dan evaluasi. TTG Mesin Chopper digunakan untuk mencacah dan menghaluskan hijauan untuk mendapatkan ukuran lebih seragam dan mudah difermentasi, serta effisiensi waktu dan biaya. Hasil kegiatan menunjukkan peningkatan pengetahuan dan pemahaman mitra dalam pengoperasian dan perawatan mesin, prosedur fermentasi, serta pencatatan biaya produksi sederhana. Program ini memperlihatkan bahwa transfer teknologi tepat guna dari perguruan tinggi dapat menjadi solusi praktis dalam mengubah limbah pertanian menjadi pakan bernilai, sekaligus mendukung ekonomi sirkular, pemberdayaan desa, dan keberlanjutan usaha peternakan rakyat

Abstract

This comprehensive study examines the potential and suitability of implementing Solar Power Plant (PLTS) as a renewable energy solution in Pelawi Utara Village. The study used a quantitative approach through primary data collection in the form of community energy demand surveys and solar energy potential measurements, as well as secondary data from relevant agencies. Potential analysis showed that the research location has an average solar radiation of 4.8 kWh/m²/day with an effective irradiation duration of 5 hours per day, while the community's electrical energy needs reach an average of 900 kWh per month with a peak load of 35,094 kW. The technical feasibility study indicated that the implementation of a 45,000 kW solar power plant could meet 30% of the community's total energy demand. The economic analysis showed investment feasibility with a payback period of 8 years, Net Present Value (NPV) of IDR 165,000,000,000, and Internal Rate of Return (IRR) of 15%. The results of this comprehensive study conclude that PLTS is an appropriate renewable energy solution for Pelawi Utara Village based on resource potential, technical aspects, and economic feasibility.
