The condition of construction implementation in Indonesia, which had been disrupted due to the number of construction accidents in the span of 2017 – 2019, began to bounce back in mid 2019. The Indonesian government has also issued various regulations, standards, systems and protocols to improve construction safety performance in Indonesia. Some of these safety assurance management standards and systems are mandatory in construction work environments. Some of these mandatory standards and systems are the Occupational Safety and Health Management System (SSHMS), as well as the Construction Security, Safety, Health, and Sustainability Standards (SSHS) which in their implementation have the potential to cause various obstacles and challenges in achieving optimal, efficient, effective and integrated.. The research was conducted on twenty-two road infrastructure projects from state-owned enterprise Istaka Karya Inc. Data was collected based on interviews, questionnaires, and supporting documents. Used five independent variables X (SSHMS and SSHS), one dependent variable Y (infrastructure project performance on environmental issues), and one intervening variable Z (employee and workers understanding). Statistical analysis uses Structural Equation Modeling (SEM) - Analysis of the Moment of Structural (AMOS). The result shows a significant relationship between several variables X to Z and Y especially variables Z to Y.
