<![CDATA[The reliability of data center infrastructure inherently depends on the stability of its electrical power supply. The primary issue faced by the partner, a tech and internet company in Mataram City, was the reliance on manual electrical monitoring methods that lacked responsiveness to power anomalies outside operational hours, posing a severe risk of enterprise hardware damage and costly downtime. This community service activity aimed to implement an Internet of Things (IoT)-based AC power stability monitoring system while concurrently enhancing the technical capacity of the partner's IT staff. The execution methods comprised field observation, technology diffusion integrating Thera TEM-25 industrial sensors with a USR-DR302 Modbus Gateway into a PRTG Network Monitor dashboard hands-on technical training, and collaborative Standard Operating Procedure (SOP) development. The results demonstrated an exceptionally high operational reliability, with a system uptime of 99.8268% and 100% data coverage at 60-second sampling intervals. The system successfully and precisely documented short-term voltage sag anomalies as low as an extreme 195.1 V AC. Beyond technical deployment, a tangible transfer of technology was achieved, empowering the partner's IT staff to independently interpret anomaly graphs and execute preventive measures. Furthermore, isolating the system architecture within a local intranet ensured optimal cyber security since critical data remains unexposed to the public internet. This digital transformation has successfully shifted the partner's maintenance paradigm from a conventional-reactive approach to a proactive, Condition-Based Maintenance strategy.]]>
