Optimizing Energy Efficiency and Power Quality Through A Web-Based Audit Platform
Downloads
Energy efficiency and power quality are crucial for sustainable campus operations, particularly in higher education institutions seeking to minimize energy waste and ensure compliance with national electrical and safety standards. This study aimed to develop and evaluate a web-based audit platform for optimizing energy efficiency and power quality. Grounded in the Technology Acceptance Model (TAM) and ISO/IEC 25010 software-quality standards, the research employed a survey design complemented by semi-structured interviews to assess platform acceptability among a purposive sample of 35 faculty, staff, and experts. Results indicate robust acceptability, with overall mean ratings exceeding 4.4 on a 5‑point Likert scale across all constructs, and Cronbach’s alpha values ranging from 0.710 to 0.865, confirming instrument reliability. One‑sample t‑tests (p < 0.001) demonstrated significantly positive perceptions. A multiple regression model accounted for 78.2% of the variance in behavioral intention (R² = 0.782), with work compatibility (r = 0.838) and perceived usefulness (r = 0.795) as the strongest predictors. Compliance features effectively embedded PEC and OSHS standards, and platform reliability and maintainability were highly rated (M > 4.5). The findings support the platform’s feasibility as a sustainable infrastructure and environmental performance tracking tool, recommending institutional adoption to enhance campus energy management, system safety, and operational efficiency at the university.
