This research aims to analyze the disturbances that occur at the Sultan Syarif Kasim II Meteorological Station Weather Radar and provide appropriate treatment to stop the source of the disturbance. For this reason, the following steps are arranged: Literature studies, preparation for mitigating interference, measurement, interference analysis, and interference resolution. After applying measurements, the following results were obtained: The interference location point is on the azimuth line (8.07° and 37.84°), Noise floor level -107.3 dBm at a frequency of 6500 MHz when SSID PermanaNET#02 5825 MHz is on, noise floor level -111.1 dBm at a frequency of 6500 MHz when SSID PermanaNET#02 5825 MHz is off, distance between BMKG Radar station to Point of Presence (PoP) ISP PT. Medianusa Permana is very close ±200 meters, antenna SSID PermanaNET#02 5825 MHz pointing to the BMKG Radar Station, and sensitivity of the EEC DWSR–2500C Radar Device is -113 dBm. Interference at the 6500 MHz radar frequency comes from the Out Of Band Emission frequency 5825 MHz (SSID PermanaNET#02). Following this, the interference is mitigated by the off-air method, which is deactivation of the PermanaNET SSID#02 device.

The importance of solar photovoltaic (PV) systems has increased over the past ten years due to the solar PV industry's explosive growth. To ensure the reliable, safe, and efficient operation of residential PV systems, fault detection is crucial. Early classification of faults can improve PV system performance and reduce damage and energy loss. Many recent studies have focused on classifying and detecting PV faults but most of them are limited to specific reasons like Real-world data can be restricted, unbalanced, or include noise, all of which may decrease the effectiveness of ML models. This paper proposes a method for identifying and classifying both physical and electrical faults in the PV array system applying a machine learning (Random Forest) model to that is trained using a synthetic photovoltaic training database. Make use of a synthetic PV database opens the door to a more precise, effective, and scalable PV system by addressing the limitations of real-world data. MATLAB is used to create a synthetic database while scikit-learn tool in Jupyter Notebook is used to train an ML model are the two main steps in this paper. The performance of the proposed model is compared with the existing ML model and achieves the most effective algorithm offering higher accuracy in detection of 98.6% and classification accuracy is 94.2% for both physical and electrical faults after being successfully tested on real-world datasets and trained on historical data from the PV array system (PV Database).

The study investigates the dynamic performance and energy harvesting efficiency of different cantilever configurations using numerical simulations. It examines factors such as material properties, geometrical parameters, and excitation conditions to optimize the design for enhanced energy harvesting capabilities. The research contributes to understanding how different cantilever designs affect the overall performance and efficiency of piezoelectric energy harvesters. Vibrational energy harvesters, also known as MEMS, have become popular due to their efficiency and ease of inclusion in microsystems. COMSOL Multiphysics was used to simulate six different forms of piezoelectric bimorph cantilevers for energy harvesting. Designs were analyzed, with each design having a distinct arrangement of proof masses. Design 01 had a rectangular cantilever with a proof mass connected to its top surface, Design 02 used a rectangular cantilever, Design 03 used a novel approach, Design 04 used a trapezoidal cantilever, and Design 05 preserved the trapezoidal form but moved the proof mass to the structure's base. Design 06 successfully completed the trapezoidal cantilever. The study found that design 04 had a significant advantage in power production efficiency at higher resistor values, surpassing design 01 in power output. The use of these varied designs allows for an exhaustive examination of piezoelectric bimorph cantilever configurations, potentially leading to insights that may enhance energy harvesting effectiveness in various applications.

A stable Internet connection is needed to make it easier to manage school data. However, the more teachers or students who use the Internet simultaneously without any bandwidth management, the more it will affect the speed of the Internet connection and decrease its performance. Based on these problems, bandwidth limitation is needed to limit speed and maintain bandwidth quality so that the Internet remains optimal even though it is being used simultaneously. Several bandwidth limitation methods can be applied, including the Hierarchical Token Bucket (HTB) and Peer Connection Queue (PCQ) methods. Tests are needed to determine which method is more suitable to implement. In this study, the two methods will be applied to SDS IT Sahabat Muslim to analyze these two methods. Each bandwidth management method was applied, and several tests were carried out, such as internet speed testing, watching online videos via YouTube, testing virtual meetings using Zoom, and testing downloading files. Then, a comparison was made from the results of the trials of each method, and the results showed that the PCQ method was more suitable to be applied at SDS IT Sahabat Muslim than the HTB with average throughput for speed test, YouTube, zoom, download, and upload respectively 1107 kbps, 1154 kbps, 1226 kbps, 1452 kbps, and 1441 kbps and delay of around 6.74 ms.

The transmission system distributes electricity from power plants to substations before reaching consumers. During this process, obstacles such as power loss and voltage regulation occur, which must meet specific standards to prevent equipment damage. Power loss can result from factors like corona effects and insulator leakage. This study aims to analyze power loss and voltage regulation based on daily peak load data at 14:00 over 15 days, recording current and voltage values on the extra-high voltage Krian-Grati transmission network. This system uses ACSR Gannet conductors with a cross-sectional area of 392.84 mm² and a length of 79.41 km, having a resistance of 0.00086 Ω/km. Manual calculations for short transmission lines show a voltage difference between sending and receiving ends, with the sending voltage being slightly higher due to reactance, preventing a drastic voltage drop. Over 15 days in December 2024, voltage regulation did not exceed the standard maximum of <10%, with the highest recorded value at 4.7%. The highest power loss occurred on day 7 at 0.089 MW, while the lowest was on day 9 at 0.023 MW. The total power loss over 15 days reached 1.024 MW, with a daily average of 0.068 MW.

Samsung's energy storage systems for data centres are pioneering, being the first lithium-ion battery cabinets to meet stringent UL rack-level safety standards. Integrating an Uninterruptible Power Supply (UPS) with an energy storage system is essential for ensuring reliable power to critical loads. Samsung lithium-ion battery systems are engineered to exceed the demands of large-scale UPS applications. This paper reviews, implements, and analyses Samsung lithium-ion batteries compared to lead-acid batteries, particularly with the Vertiv UPS system. A 400 kVA Vertiv UPS was connected to 17 Samsung SDI lithium-ion batteries in a robust rack configuration, each rated at 30.4 Vdc and 67 Ah. Simultaneously, a lead-acid battery setup consisting of forty 12V 67Ah batteries housed in a specialized cabinet was evaluated. A 360 kW resistive load was applied to the UPS output, and an external mains failure was simulated while measuring end-of-discharge time. Results showed that the Samsung SDI lithium-ion battery system reached a cut-off voltage of 393.5 VDC at 954.0 A, achieving 58 minutes of runtime, while the lead-acid system recorded 395.2 VDC at 962.0 A, lasting 49 minutes. These findings confirm the superior performance of lithium-ion batteries in UPS applications, reinforcing their role in data centre energy storage.

This paper presents a comprehensive review of static transfer switch (STS) applications in AC power systems, with a focus on enhancing reliability and fault tolerance. The review outlines the fundamental requirements for effective STS deployment, including the necessity of two truly independent and nominally synchronized AC power sources, optimal placement of the STS near protected loads, and proper grounding practices to minimize single points of failure. The analysis synthesizes recent literature on STS topologies, control mechanisms, and integration with uninterruptible power supplies (UPS), highlighting the importance of redundancy and the persistent challenges of achieving source independence and synchronization. Empirical studies and case analyses are discussed to demonstrate the impact of STS design and deployment on minimizing risks to sensitive loads. The paper concludes by providing practical recommendations and identifying future research directions for further improving STS solutions in resilient AC power systems.
