Penilaian Risiko Ergonomi Sektor Perkantoran Menggunakan Metode Rapid Office Strain Assessment (ROSA) di Perusahaan Jasa Pertambangan

Abstract

In the mining services company’s Human Capital (HC) & Legal Division, all work is administrative and
office-based. Employees in this division spend an average of eight hours per day seated at computers to complete
their tasks. Initial observations, based on a survey using SNI 9011:2021 Annex F completed by 51 respondents,
revealed widespread postural errors at work. These errors are a primary risk factor for musculoskeletal disorders
(MSDs) and can significantly reduce productivity. To address this, a workstation risk assessment was conducted
using the Rapid Office Strain Assessment (ROSA) method. Data were collected through direct observation and
measurement of body angles with the Angulus application, followed by posture evaluation using the ROSA
worksheet to determine final ROSA scores. Scores ??5 are classified as “at risk,” while scores <?5 are considered
“acceptable.” Four employees representing different job levels—department head, division head, administrative
staff, and Corporate Social Responsibility (CSR)—were selected to ensure the results reflect ergonomic conditions
across the entire HC & Legal Division. The assessment showed that all four respondents scored ??5, indicating an
ergonomic risk, with the highest score of 8 for the administrative staff and the lowest score of 5 for the department
head. These elevated scores were attributed to inadequate workstation facilities, limited employee awareness of
proper equipment use, and prolonged working durations.
