Pengaruh Sarana Prasarana Dan Lingkungan Kerja Terhadap Kinerja Guru Sma Negeri 1 Batukliang Utara Di Kabupaten Lombok Tengah

Teacher performance is a key determinant of educational quality and the successful implementation of learning processes. Among the factors that may influence teacher performance are the adequacy of educational facilities and infrastructure, as well as the quality of the working environment. This study aims to examine the influence of facilities and infrastructure, together with the work environment, on teacher performance at SMA Negeri 1 Batukliang Utara, Central Lombok Regency. A quantitative approach with a descriptive research design was employed. The study involved all 33 active teachers using a total sampling technique. Data were collected through a structured questionnaire based on a five-point Likert scale and analyzed using multiple linear regression with IBM SPSS Statistics version 26. The findings reveal that facilities and infrastructure do not have a significant partial effect on teacher performance (β = 0.017; p = 0.933), whereas the work environment has a positive and statistically significant effect (β = 0.770; p = 0.003). Simultaneously, both independent variables significantly influence teacher performance (F = 10.840; p < 0.001), explaining 41.9% of the variance in teacher performance, while the remaining 58.1% is attributable to other factors not included in the research model. These findings indicate that a supportive and conducive work environment plays a more substantial role than educational facilities in improving teacher performance. Therefore, school management should prioritize the creation of a positive work environment while continuing to improve educational facilities to support teachers' professional responsibilities.
