Due to the high level of risk, every organization is required to implement the Occupational Health, Safety, and Environmental Management System, or OHSEMS, during the construction process. Academic activities, laboratory research, and building work all require HSE management at XYZ University. The university's implementation of the OHSEMS in the construction process is done to predict work accidents that can impair the organization's performance. This study examines the involvement of OHSMS stakeholders in construction activities. The study then organizes strategies for stakeholders to improve the organization's performance. The case study technique was employed in this study, with questionnaires distributed to 18 respondents and five experts. The results of the questionnaires will be analyzed by statistical and stakeholder analysis. According to the study's conclusions from stakeholder analysis, there are 36 HSE stakeholders, including 30 primary and six subsidiary stakeholders. The Head of the HSE Organization, the Facility Operation and Maintenance Directorate, and contractors are examples of stakeholders who have a positive impact on the organization's performance. However, according to linear regression result, one of the consultant's strategies had no effect on the organization's performance. Workers can use the stakeholder engagement strategy to improve organizational performance by hosting a construction work evaluation meeting.
