Abstract

BPR or business process reengineering is a process to achieve radical improvements in terms of time, quality, rewards, and of course costs by simultaneously redesigning processes, organizations, and information systems. In this study, IT/technology and HR factors (human resources) are used in re-engineering public facilities assisted by expert systems to create efficiency and effectiveness and increase value. The main factor used in this study is the management system, especially for making changes to the organizational structure, improving the administration system, and Relationship Management. The model suitability test in this report uses several criteria, including Chi-Square, GFI, AGFI, and RMSEA. Although the final model obtained a high Chi-square value (13.157) with a probability of zero, because several other criteria were met with an AGFI value above 0.9 and an RMSEA value below 0.08, the model is considered suitable. Based on the model output, it is known that not all antecedent variables have a significant influence on the consequent variables. Likewise, not all hypotheses are accepted. All antecedent variables cannot explain the consequent variables because the R2 value is less than 0.5.

Abstract

CCTV monitoring activities are static tasks that require continuous visual focus and prolonged sitting, making operators prone to physical fatigue, visual impairment, and decreased performance. Common problems include non-ergonomic work postures, thermal discomfort, and lighting glare on monitors. This study aims to evaluate CCTV operator performance through a comprehensive ergonomic approach that includes posture analysis, work activity patterns, and environmental conditions. The methods used include work sampling to measure the proportion of productive and idle time, posture analysis using REBA to determine musculoskeletal risk, and measurement of environmental parameters such as temperature, air velocity, viewing distance, and lighting quality. The results showed a REBA score of 3 (low risk but improvement needed), operator focus time of only 8–10 minutes, normal idle time of 15 minutes, and an allowance of 17 minutes. Nighttime thermal conditions were below comfort standards, and glare was found to interfere with visibility. These findings confirm the need to redesign workstations and improve working conditions to improve CCTV operator performance.
