Abstract

The existence of substation operators is essential for monitoring substation equipment and operating control rooms. In addition, substation operators also have other tasks, such as inspecting substation equipment in the switchyard or in-service inspection (Level 1 inspection). This condition is less than ideal because the operator cannot monitor the control room continuously while in the switchyard. The control panel at the substation is equipped with an alarm annunciator, which is auxiliary equipment that serves to provide warning signs to the operator regarding which protection functions are working. Therefore, it is necessary to have a monitoring system that can provide real-time information about the condition of the control panel alarm annunciator. This research models a fault alarm monitoring system that can provide notification messages according to the type of fault automatically through the Telegram application. The system test results show the average value of 100 test data on the five types of fault, resulting in an accuracy rate of 100%, a precision rate of 100%, a recall rate of 100%, an error rate of 0%, and an F1-score rate of 100%. This is because all test data on the five types of fault were detected correctly, and no test data from other types of fault was detected as the five types of fault. Based on these averages, it can be concluded that using a confusion matrix to measure the performance of the fault alarm monitoring system on the IoT-based control panel annunciator alarm shows excellent system performance results.

Abstract

Hybrid power generation, a power plant that combines two or more plants, continues to grow along with technological advances. The performance of these power plants relies heavily on effective switching and monitoring systems. Monitoring data is critical in maintenance scheduling, preventive intervention, and the timely identification and assessment of environmental changes. One of the switching and monitoring technologies integrated with the Internet is the Internet of Things (IoT) technology. This study introduces a system design capable of wirelessly performing switching operations and transmitting real-time data to a hybrid power plant monitoring system through an application. Test results demonstrate that the system successfully executes automatic switching between the hybrid power plant and the PLN electricity grid based on accumulator voltage thresholds. The monitoring data analysis reveals MAPE values of 2.959% and 3.577% for the voltage and current of the hybrid power plant, and a MAPE of 1% for the accumulator voltage. The voltage and load current readings also exhibit MAPEs of 0.604% and 8.625%. Based on the test results, it can be concluded that this device shows the ability of the system to automate the switching of resources to the load and monitor the hybrid power plant very well, with the smallest MAPE value achieved of 0.604%.

Abstract

Pembangkit Listrik Tenaga Surya (PLTS) merupakan energi terbarukan yang ramah lingkungan dengan memanfaatkan energi alam yaitu sinar matahari sebagai sumber utama, sumber energi matahari juga dapat digunakan untuk mengatasi krisis energi yang ramah lingkungan, mengurangi pemanasan global (global warming) dan pencemaran udara. PLTS bekerja berdasarkan energi matahari akan diubah menjadi energi listrik dengan memanfaat panel surya atau solar cell. Tujuan dari kegiatan PKM ini dengan melakukan perancangan dan membuat suatu perangkat portable PLTS untuk masyarakat (dalam lingkup umum) yang berkativitas dan bekerja diluar rumah yang tidak terjangkau energi listrik. Solar cell yang digunakan berjenis polycristaline, dilengkapi SCC, baterai, satu unit box panel. Perlu juga adanya pemantauan tegangan dan arus guna memudahkan pada saat proses perawatan, perancangan alat monitoring arus dan tegangan menggunakan microcontroller arduino uno dengan pembacaan sensor. Hasil penelitian ini diharapkan dapat meningkatkan produktivitas pertanian melalui pembuatan portable solar cell yang dapat digunakan untuk sumber energi pompa untuk mengairi sawah, penerangan maupun penggerak peralatan elektrik lainnya. Dengan demikian, teknologi yang dikembangkan dapat berkontribusi dalam menciptakan sistem yang lebih ramah lingkungan, berkelanjutan, dan efisien yang dapat membantu masyarakat Kokop.

Abstract

The research discusses the evaluation of electrical systems in multi-storey buildings, including analysis of compliance with PUIL 2011 standards and integration of Faraday Cage-based lightning protection systems. This study focuses on the Pasar Baru Bandung Building, with the aim of assessing the efficiency and safety of the electrical system used. The research method is carried out through the stages of field observation, data collection, and data processing. Observations were made to identify electrical equipment and assess the feasibility of its use. Data collection includes load capacity and single line diagrams, which are then processed to determine the value of Strong Current Conductivity (KHA) and Drop Voltage. The results of data processing were compared with existing data and analysed based on applicable standards. The results show that the power distribution system in Pasar Baru Bandung Building has been designed with high efficiency, with organised power distribution through main panels and sub-panels. The electrical protection evaluation shows that the grounding and earthing system has met the safety standards to prevent electrical faults. In addition, lightning protection analysis with the Rolling Sphere method ensures that the building's protection against lightning strikes is at an optimal level. The benefit of this study is the comprehensive examination of the electrical system, considering power distribution, protection, and energy efficiency. Despite challenges like inaccuracies in voltage drop measurement due to factors like environmental conditions and equipment age, the research still has a significant impact on improving the safety and efficiency of electrical systems in tall buildings.

Abstract

Pembangkit Listrik Tenaga Surya (PLTS) merupakan salah satu sumber energi terbarukan yang potensial di Indonesia, namun daya keluarannya sangat dipengaruhi oleh kondisi atmosfer yang bersifat fluktuatif. Penelitian ini bertujuan mengembangkan model prediksi jangka sangat pendek daya keluaran PLTS menggunakan metode Long Short-Term Memory (LSTM) berbasis Sky Clearness Index (SCI). Data penelitian berupa tegangan, arus, dan SCI dikumpulkan dari sistem PLTS Universitas Negeri Surabaya dengan interval 5 menit selama periode Mei–Juni 2025. Model LSTM dirancang dengan dua lapisan tersembunyi, Adam Optimizer, dan fungsi loss Mean Squared Error (MSE). Dataset dibagi menjadi 80% data latih dan 20% data uji. Evaluasi kinerja model dilakukan menggunakan Root Mean Square Error (RMSE), Mean Absolute Error (MAE), dan Mean Absolute Percentage Error (MAPE). Hasil penelitian menunjukkan bahwa model LSTM berbasis SCI mampu memprediksi daya keluaran PLTS dengan akurasi tinggi, dengan nilai RMSE sebesar 0,644, MAE sebesar 0,536, dan MAPE sebesar 3,66%. Nilai MAPE di bawah 10% menunjukkan performa prediksi yang sangat baik untuk peramalan jangka sangat pendek. Dengan demikian, integrasi SCI sebagai variabel input terbukti efektif dalam meningkatkan keandalan prediksi daya keluaran PLTS secara real-time.

Abstract

The dingo optimization algorithm (DOA) adopts the social life of dingo dogs. The dingo is a breed of ancient dog originating from Australia. Dingo hunting strategies such as assault with persecution, flocking, and scavenging behavior became the inspiration for DOA. In this paper, DOA is applied to a power system stabilizer (PSS) to dampen low-frequency oscillations (LFO) in a single-machine infinite bus (SMIB). DOA is used to obtain optimal parameters for PSS. The damping controller is designed for optimal lead-lag control. To obtain the performance of the DOA method, the results were compared with the uncontrolled method, conventional PSS, Whale optimization algorithm (WOA), and grasshopper optimization algorithm (GOA). Simulation using MATLAB with three different operating conditions, namely light load (20%), medium load (50%) and high load (100%). From the simulation using MATLAB with SMIB modeling, it was found that the application of the DOA method on PSS has the ability to reduce the average undershoot value by 28.16% and reduce the average undershoot value to 65.57% compared to the conventional PSS method.
