Abstract

Low power factor (cos φ) remains a prevalent issue in residential electrical installations, primarily due to inductive appliances such as air conditioners, refrigerators, and water pumps, which increase reactive power and reduce overall system efficiency. This condition leads to voltage drops, increased current flow, and higher I²R losses, affecting electricity expenditure and long-term equipment reliability. To address this problem, this study proposes an automatic power factor correction system based on reactive power compensation, where capacitors function as local suppliers of reactive power to stabilize voltage and reduce grid loading. The system utilizes an Arduino Nano microcontroller integrated with a PZEM-004T sensor for real-time monitoring of voltage, current, and power factor. Based on the measured parameters, capacitor switching is performed using relay-based control to enable adaptive compensation according to load variations. Experimental testing was conducted under real household operating conditions for a total duration of four months, including pre- and post-intervention measurements. The results showed a substantial improvement in power factor, increasing from 0.79–0.82 to 0.91–0.99 after capacitor bank installation. Current consumption also decreased—for example, from 4.23 A to 3.50 A in Week 1 and from 9.61 A to 8.10 A in Week 5, indicating reduced power losses and improved voltage stability. Furthermore, energy usage declined from 737 kWh to 605 kWh over two months, resulting in an energy saving of 17.9%. In conclusion, the proposed system demonstrates that low-cost automated power factor correction can effectively enhance residential energy efficiency and offer measurable economic benefits for household consumers.

Abstract

Purpose – This study aimed to develop and evaluate CircuitPintar, a website-based learning medium designed to improve the competencies of vocational high school students in the Basic Electrical Theory element of the Electrical Installation Engineering program.Methodology – The research employed a Research and Development approach using the ADDIE model: analysis, design, development, implementation, and evaluation. The implementation trial involved 35 Grade X TITL students at SMKN 3 Surabaya. Data were collected through media and material validation sheets, teacher and student response questionnaires, a 25-item cognitive test, and psychomotor and affective observation rubrics. Data were analyzed using percentage-based validity and practicality criteria, Shapiro-Wilk normality tests, paired-sample t-tests, and normalized gain (N-gain).Findings – CircuitPintar was categorized as highly valid in media validation (91%) and material validation (94%). Practicality was also high, with teacher responses of 91% and student responses of 86%. Students’ mean scores increased from 72.74 to 88.17 in the cognitive domain, from 71.77 to 88.74 in the psychomotor domain, and from 73.40 to 88.00 in the affective domain. All improvements were statistically significant (p < 0.001), and N-gain values for all domains were in the moderate category.Contribution – This study presents an empirically tested model of website-based vocational learning media that combines concept mastery and virtual practice on a single platform, offering a practical reference for developing similar digital media for other technical and vocational subjects.

Abstract

Guru Sekolah Menengah Kejuruan (SMK) memiliki peran strategis tidak hanya sebagai pengajar, tetapi juga sebagai agen pengembangan inovasi pendidikan berbasis praktik dan penelitian. Namun demikian, banyak guru masih menghadapi kendala dalam menyajikan hasil penelitian dan inovasi pendidikan ke dalam bentuk artikel ilmiah yang memenuhi standar publikasi. Kegiatan Pengabdian kepada Masyarakat (PKM) ini bertujuan untuk meningkatkan kompetensi guru SMKN 1 Bojonegoro dalam menyusun dan menyajikan hasil penelitian serta inovasi pendidikan melalui pendampingan penulisan artikel ilmiah. Metode pelaksanaan meliputi ceramah, diskusi, latihan terbimbing, dan project-based learning yang dilaksanakan secara luring. Peserta kegiatan berjumlah 30 guru dari berbagai bidang keahlian. Hasil kegiatan menunjukkan peningkatan signifikan pada pemahaman struktur artikel ilmiah (dari 20% menjadi 85%), kemampuan mengakses dan menggunakan sumber referensi ilmiah (dari 30% menjadi 90%), serta kesiapan menyusun draft artikel ilmiah (dari 10% menjadi 80%). Temuan ini menunjukkan bahwa pendampingan yang terstruktur dan kontekstual efektif dalam meningkatkan kompetensi profesional guru, khususnya dalam publikasi ilmiah. Kegiatan ini berkontribusi pada penguatan budaya akademik dan peningkatan kualitas inovasi pendidikan di tingkat sekolah.

Abstract

Single-phase induction motors are widely used in domestic and industrial applications, but they have the main disadvantage of significant initial current surges, which have the potential to damage components and degrade power quality. This research proposes a solution through the design and implementation of an Arduino Nano-based soft start automation system to overcome these surges. The developed system uses Arduino Nano as the main microcontroller integrated with the PZEM-004T sensor for real-time monitoring of electrical parameters, as well as relays as an efficient switching mechanism. The method applied is the manipulation of the value of the resistor to limit the initial current, with the aim of measuring the effectiveness of the system in reducing the current surge. Focusing on testing a fully functioning system, the study is expected to prove a drastic decrease in initial current spikes. The results of this study can show that the Arduino Nano-based soft start automation system is effective in improving the performance and efficiency of induction motors, as well as being a practical guide for similar applications in the industry.
