<![CDATA[The Highway Laboratory carries significant occupational safety risks and environmental impacts; however, the implementation of standard operating procedures (SOPs) that integrate occupational safety and environmental management aspects remains suboptimal. This study aims to analyze student satisfaction levels toward integrated SOPs based on ISO 45001 and ISO 14001 as an effort to harmonize toward a green laboratory in the Highway Laboratory. This study employed a descriptive quantitative approach using a survey method involving 150 Civil Engineering students from the 2023 cohort who had completed the full series of laboratory practicum sessions. Data were collected using a structured questionnaire consisting of 30 statement items across six measurement dimensions and analyzed using descriptive statistics. The results revealed that the overall student satisfaction level fell into the "Moderately Satisfied" category, with three dimensions obtaining the lowest scores, namely the implementation of occupational health and safety based on ISO 45001, environmental management based on ISO 14001, and the application of the green laboratory concept. These findings indicate that the existing SOPs have not adequately accommodated occupational safety, health, and environmental sustainability aspects. This study affirms the urgency of developing integrated SOPs that harmonize ISO 45001 and ISO 14001 as the foundation for realizing a safe, healthy, and sustainable green laboratory.]]>
