Abstract

Abstrak: Mitra Katering Indah Akbar Hafis mengalami kendala produksi dan manajemen energi akibat tingginya ketergantungan pada listrik PLN untuk mengoperasikan peralatan dapur seperti oven, lemari pendingin, dan pemanas. Pemadaman listrik yang sering terjadi menghambat proses produksi, menurunkan mutu layanan, serta berpotensi menimbulkan kerugian. Selain itu, ketiadaan sistem manajemen energi menyebabkan pemborosan daya dan biaya operasional tinggi. Program pengabdian ini bertujuan menerapkan Solar Home System (SHS) Off-Grid sebagai solusi efisiensi energi sekaligus upaya mendorong pemanfaatan energi terbarukan yang ramah lingkungan. Metode pelaksanaan meliputi persiapan, sosialisasi, pelatihan, instalasi SHS, serta pendampingan dan evaluasi. Kegiatan melibatkan 30 peserta dari mitra dengan evaluasi berupa angket post-test yang terdiri dari 10 pertanyaan. Hasil menunjukkan keberhasilan program, ditandai dengan 85% peserta menyatakan setuju dan 15% cukup setuju terhadap manfaat kegiatan. Hal ini membuktikan peningkatan pemahaman peserta mengenai renewable energy sekaligus menunjukkan potensi penghematan energi melalui penerapan SHS Off-Grid untuk mendukung efisiensi dan pemberdayaan industri rumahan.Abstract: The partner, Katering Indah Akbar Hafis, faces production and energy management challenges due to its high dependence on PLN electricity to operate kitchen equipment such as ovens, refrigerators, and heaters. Frequent power outages disrupt the production process, reduce service quality, and potentially cause financial losses. In addition, the absence of an effective energy management system leads to power waste and high operational costs. This community service program aims to implement an Off-Grid Solar Home System (SHS) as an energy efficiency solution while promoting the use of environmentally friendly renewable energy. The implementation stages include preparation, socialization, training, SHS installation, as well as mentoring and evaluation. The activity involved 30 participants from the partner, with evaluation conducted using a post-test questionnaire consisting of 10 questions. The results indicate the program’s success, with 85% of participants strongly agreeing and 15% agreeing with its benefits. This demonstrates an improvement in participants’ understanding of renewable energy and highlights the potential for energy savings through SHS Off-Grid implementation to support efficiency and empower home-based industries.

Abstract

Harmonics are produced by non-linear loads such as televisions, computers, microwaves, fluorescent lamps that use electronic ballasts and others. The harmonic content contained in non-linear loads causes the quality of electrical power to become poor and the quality of electrical power to decrease, the greater the use of non-linear loads, it is estimated that the harmonics generated will be greater and can disrupt the system performance of other electronic equipment and can also cause overheating of electrical power sources, plastic manufacturing company measurements, Source Voltage Balanced (V peak) Unbalanced (V peak) 312∠ 00, 311∠ -1200, 312∠ 1200, Phase R 3.23 Ampere, Phase S 3.24 Ampere Phase T 3, 24 Amperes as in figure 2a, and THD Current in Phase R 25%, Phase S 23% Ampere Phase T 24%, the total harmonic distortion was above 5% and the analysis for the single tuned filter was C value > 50.64 μF, L value > 10.093 H, and R value > 50.98 Ω. then after, harmonic values, a filter was installed to reduce the THD value to 1.4% and the overall THD value was below 5% in accordance with IEEE standards.

Abstract

Three-phase load imbalance in power transformers is one of the main problems that can reduce efficiency, increase power losses, accelerate the increase in winding temperature, and reduce the life of transformer insulation. This condition often occurs in distribution systems due to uneven load growth between phases. This study aims to optimize three-phase load balancing to improve the efficiency and reliability of power transformers at the Tanjung Morawa Substation. The research method uses a quantitative approach based on transformer operational data, including measuring the current of each phase, calculating the percentage of load imbalance, analyzing copper losses, and evaluating efficiency and reliability indices. The optimization model is carried out by simulating load redistribution between phases using a mathematical approach to minimize current deviations from the average current. Evaluation parameters include reducing power losses, increasing transformer efficiency, and improving the value of the imbalance factor according to IEC and IEEE standards. The results show that before optimization, the level of load imbalance was in the moderate to high category, which resulted in increased power losses and increased operating temperatures. After the load balancing optimization process, there was a significant decrease in the percentage of imbalance, a decrease in power losses, and an increase in transformer efficiency. Furthermore, the estimated insulation life shows an improvement due to reduced thermal stress. This study demonstrates that a systematic, data-driven three-phase load balancing optimization strategy can sustainably improve the performance, efficiency, and reliability of power transformers. The proposed model can be implemented as part of an asset management and preventive maintenance strategy in electric power systems.
