Abstract

Application of Multi-Layer Perceptron neural network to fault classification in high-voltage transmission lines is demonstrated in this paper. Different fault types on protected transmission line should be detected and classified rapidly and correctly. This paper presents the use of Discrete Wavelet Transform energy features combined with zero sequence current magnitude as input features for neural network classifier. The proposed method uses eight extracted features to learn hidden relationship in fault signal patterns. Using proposed approach, fault detection and classification of all 11 fault types could be achieved with high accuracy. Improved performance is experienced once the neural network is trained sufficiently with 1188 fault samples, thus performing correctly when faced with different system conditions. Results of performance studies show that proposed neural network-based classifier achieves 96.18% average accuracy, which demonstrates that it can improve the performance of conventional fault classification algorithms, which in turn can provide more efficient solutions in the management and protection of high voltage electrical systems.

Abstract

Abstract Electrocardiogram is a medium-tech diagnostic electromedical device that is widely available in healthcare facilities. Electrocardiogram maintenance is very important to maintain the performance and accuracy of reliable results for medical diagnosis. Suboptimal Electrocardiogram maintenance can be caused by various factors, including user negligence, improper use, component damage, and lack of preventive maintenance. Therefore, this study aims to determine the selection of preventive maintenance strategies on electrocardiograms that are right on target in order to minimize damage, maintain the reliability of the electrocardiogram, and provide optimal maintenance. The research method used is the Analytical Hierarchy Process (AHP). The results obtained from the AHP method are the Warehouse Backup criteria have the highest priority weight of 0.184 and the alternative with the highest priority weight is Periodic Maintenance of 0.3744, then followed by Repair Maintenance (Schedule Overhaul) of 0.3184 and the last is Condition Based Maintenance of 0.3072. The periodic maintenance strategy has the greatest weight, so it is chosen as the most appropriate strategy to be used as optimal maintenance and is expected to be an effective solution so that it can successfully reduce damage and maintain the reliability of the Electrocardiogram. Keywords: analytical hierarchy process (AHP), maintenance, maintenance strategy

Abstract

Program pengabdian kepada masyarakat yang dilaksanakan oleh Universitas Islam Sultan Agung Semarang di SD Negeri Bajo Lohoa, Desa Tanomeha, Kecamatan Kaledupa Selatan, Kabupaten Wakatobi, bertujuan mendukung revitalisasi dan digitalisasi sekolah di wilayah 3T (Tertinggal, Terdepan, Terluar) yang masih menghadapi keterbatasan pasokan listrik sebagai kendala utama dalam pembelajaran berbasis teknologi. Kondisi keterbatasan energi listrik tersebut menyebabkan proses digitalisasi pembelajaran belum berjalan optimal dan membatasi pemanfaatan perangkat elektronik pendukung kegiatan belajar mengajar. Untuk menjawab permasalahan tersebut, tim pengabdian bekerja sama dengan PT PLN (Persero) ULP Wangi-Wangi melaksanakan serangkaian tahapan kegiatan yang sistematis, meliputi survei lapangan guna mengidentifikasi kebutuhan teknis sekolah, koordinasi dengan pihak sekolah dan PLN, pemasangan perangkat SuperSun berbasis tenaga surya berupa panel surya dan instalasi sistem kelistrikan pendukung, uji coba operasional peralatan, serta sosialisasi penggunaan dan perawatan sistem kepada guru dan pengurus sekolah agar mampu mengelola perangkat secara mandiri dan berkelanjutan. Hasil kegiatan menunjukkan bahwa sekolah kini memiliki sumber listrik alternatif yang lebih stabil dan andal, sehingga memungkinkan penggunaan perangkat pembelajaran digital secara optimal, meningkatkan efektivitas proses belajar mengajar, serta memperkuat pemahaman warga sekolah terhadap konsep energi terbarukan dan pentingnya transisi menuju energi bersih. Dengan demikian, program ini tidak hanya mendukung peningkatan kualitas pendidikan melalui digitalisasi, tetapi juga berkontribusi nyata terhadap pemerataan akses energi dan pendidikan serta peningkatan literasi energi bersih di wilayah kepulauan seperti Kabupaten Wakatobi.

Abstract

This study aims to evaluate the accuracy and effectiveness of several domestic pulse oximeter brands (Elitech, Kaltech, and Endo) and a foreign brand (GE), calibrated using the Prosim SPOT Light SpO₂ Pulse Oximeter Tester. This quantitative study involved three domestically produced oximeters and one imported unit. The oxygen saturation setpoints were varied at 80%, 85%, 90%, 95%, 97%, 98%, 99%, and 100%, with three repetitions for each. Data analysis was conducted using the GUM Uncertainty Method and ANOVA statistical testing. The results show that all oximeters have combined uncertainty (expanded uncertainty, U₉₅) values between 0.58–3.23%, with reading deviations from reference values below ±2%, within acceptable tolerance limits. Kaltech and Endo oximeters demonstrated stable performance with no significant differences across saturation setpoints after calibration. Elitech and GE exhibited higher sensitivity to oxygen saturation variations, particularly at lower ranges. The One-Way ANOVA results indicated that Kaltech and Endo had p-values > 0.05, signifying no significant differences, while Elitech and GE showed p < 0.05, indicating differences between setpoints. Overall, domestically produced oximeters showed equivalent performance to imported devices after standard calibration, supporting the enhancement of Domestic Component Level (TKDN) and strengthening the independence of the national medical device industry.

Abstract

This study examines the application of the Lagrange method and Particle Swarm Optimization (PSO) in solving the Economic Dispatch problem at the Tanjung Jati B Steam Power Plant (PLTU). The main objective is to compare the effectiveness of both methods in optimizing load distribution among generation units and to evaluate potential operational cost savings compared to actual operating conditions. The optimization model minimizes a quadratic generation cost function, subject to system load demand and the power output limits of each unit. Simulation data includes daily load distribution and fuel-related parameters such as calorific value and fuel price. The results show that the Lagrange method yields an average power output of 2,367 MW, equal to the real condition, while PSO produces 1,966 MW, which is 16.94% lower. In terms of cost savings, PSO achieves an average saving of IDR 938,501, while the Lagrange method and real operation yield average savings of IDR 1,078,064 and IDR 1,073,076 respectively. In percentage terms, Lagrange shows 12.95% higher savings than PSO and 0.46% higher than the actual condition. This study highlights the importance of integrating optimization methods in power plant operations to improve efficiency and reliability of electricity supply.
