Abstract
This study examines the effect of changes in organizational structure and work mechanisms on the performance of sub-district (kelurahan) employees in South Nunukan Subdistrict, Nunukan Regency. The research employs a quantitative approach with an explanatory research design. A census method was used for sampling, involving all 64 civil servant (ASN) employees across four kelurahan in South Nunukan Subdistrict as respondents (total sampling). Data were collected through digital questionnaires (Google Forms) using a Likert scale (1–5) and analyzed using SPSS version 31, including validity tests, reliability tests, classical assumption tests, and multiple linear regression analysis. The results indicate that: (1) changes in organizational structure do not have a significant effect on employee performance (t-value = 0.644, Sig. = 0.522 > 0.05); (2) changes in work mechanisms have a positive and significant effect on employee performance (t-value = 2.141, Sig. = 0.036 < 0.05); and (3) simultaneously, changes in organizational structure and work mechanisms have a significant effect on employee performance (F-value = 7.207, Sig. = 0.002 < 0.05), with a coefficient of determination (R²) of 0.191, meaning that 19.1% of the variation in employee performance is explained by the two independent variables, while the remaining 80.9% is influenced by other factors not examined in this study. The findings suggest that bureaucratic streamlining through structural changes alone is insufficient to improve performance; rather, adjustments in work mechanisms—including assignment systems, task execution, accountability, performance management, and ICT utilization play a more decisive role.
