Abstract

This study addresses the growing need for reliable and uninterrupted electrical power systems in educational automation laboratories, where power disturbances can disrupt experiments, damage sensitive equipment, and reduce operational efficiency. The research aims to design, implement, and evaluate a Supervisory Control and Data Acquisition (SCADA) system for monitoring power source transfer status in an Automatic Transfer Switch (ATS) at the Automation Laboratory of the Electrical Engineering Department, Politeknik Negeri Manado. The study employed an experimental and engineering-based research method involving system design, hardware integration, software programming, and performance testing. The system utilized a Siemens S7-1200 Programmable Logic Controller (PLC), Modbus TCP/IP communication, and WinCC Flexible SCADA software for real-time monitoring and control. Data were collected through functional testing, communication latency measurements, and reliability evaluations over 50 transfer cycles using a 3 kW load simulation. The results showed that the SCADA-ATS system successfully monitored transfer operations with a data update latency below 200 ms and an average transfer switching time of 2.31 seconds, fully complying with IEC 60947-6-1 standards. Furthermore, the system achieved a 100% transfer success rate and accurate voltage and frequency monitoring. In conclusion, the implemented SCADA system effectively improves operational reliability, monitoring transparency, and educational learning quality in laboratory power management systems.

Abstract

This study addresses the growing need for reliable thermal monitoring systems in industrial milling machines, particularly for spindle motors and bearings that are highly vulnerable to overheating during continuous machining operations. Excessive temperature can reduce component lifespan, increase maintenance costs, and cause unexpected production downtime. Therefore, this research aims to design and evaluate a PLC-SCADA-based temperature monitoring system capable of providing real-time monitoring, automatic alarm response, and historical data logging for milling machine operation. The research employed an experimental engineering approach using a Siemens S7-1200 PLC integrated with PT100 RTD temperature sensors, Modbus TCP/IP communication, and SIMATIC WinCC Flexible SCADA software. Four PT100 sensors were installed on the spindle motor and bearing housings to acquire thermal data continuously during idle, medium-load, and full-load machining conditions. The results demonstrated that the system successfully monitored temperature in real time with a SCADA update latency below 200 ms and communication latency averaging 3.6 ms. The maximum spindle motor temperature reached 98.4°C during full-load operation, while the implemented warning and automatic cooling system successfully prevented critical overheating conditions. Temperature measurement accuracy achieved a mean absolute error of 0.41°C compared with the reference instrument. In conclusion, the proposed PLC-SCADA monitoring system effectively improves machine reliability, operational safety, and predictive maintenance capability in industrial milling machine applications.

Abstract

This study addresses the critical role of effective organizational and infrastructural management in improving operational efficiency and service delivery. Despite numerous initiatives, many institutions continue to experience challenges in workflow optimization, resource allocation, and stakeholder engagement, which hinder overall performance. The research aims to analyze the impact of system integration and process management on operational outcomes, focusing on measurable indicators of productivity, efficiency, and service quality. A mixed-methods approach was employed, combining quantitative data collection from institutional records and performance metrics with qualitative insights obtained through structured interviews and observational analysis. Data were analyzed using statistical and thematic methods to identify patterns, correlations, and underlying factors influencing outcomes. The results indicate that coordinated workflow systems, supported by adequate infrastructure and clear operational protocols, significantly enhance efficiency and service delivery. Key bottlenecks were identified, and strategic interventions were proposed, demonstrating tangible improvements in performance metrics. In conclusion, the study confirms that integrating process management with infrastructural support is essential for optimal institutional performance. Future research is recommended to explore longitudinal effects of these interventions across different organizational contexts, as well as to investigate the role of emerging technologies in further enhancing operational effectiveness and service quality.

Abstract

The increasing deployment of low-voltage distribution panels in coastal and industrial environments has created significant challenges due to corrosion, material degradation, and maintenance requirements of conventional metallic enclosures. Corrosion exposure can reduce equipment reliability, increase operational costs, and compromise electrical safety. This study aimed to design and evaluate a low-voltage distribution panel using recycled high-density polyethylene (rHDPE) as an alternative enclosure material for corrosive environments. The research employed an experimental approach involving material preparation, panel design, mechanical and electrical characterization, corrosion resistance testing, and verification based on IEC 61439-1 standards. The rHDPE compound was developed from post-consumer HDPE with magnesium hydroxide reinforcement and evaluated through tensile strength, impact resistance, dielectric strength, volume resistivity, salt spray exposure, and panel-level electrical performance tests. The results showed that the rHDPE panel achieved adequate mechanical properties with 93% retention of tensile strength and impact resistance compared with virgin HDPE, while providing superior electrical insulation performance with a dielectric strength of 18 kV/mm. The corrosion test demonstrated complete resistance after 500 hours of salt spray exposure, with no mass loss, surface degradation, or electrical resistance changes, whereas the mild steel reference panel experienced significant corrosion deterioration. IEC 61439-1 verification confirmed that the proposed panel met safety and performance requirements. The study concludes that recycled HDPE is a feasible, sustainable, and cost-effective material for low-voltage distribution panels, offering corrosion immunity, reduced maintenance, and environmental benefits.
