Benzene is a hazardous chemical found in workshop environments that can enter the body through inhalation, skin absorption, or ingestion. Once inside the body, benzene is metabolized into several metabolites—including phenol—which are subsequently excreted in urine. Urinary phenol levels can serve as a biomarker for benzene exposure. This study aimed to identify factors associated with urinary phenol levels among workshop workers at PT Bosowa Berlian Motor in 2023. A quantitative cross-sectional design was employed, and the study sample was selected through purposive sampling. Data were collected via questionnaires, observations, and laboratory analysis of urinary phenol levels. Data analysis was performed using the chi-square test at a significance level of α = 0.05. The results showed no significant association between the workers' length of employment and urinary phenol levels (p=0.282), nor between the duration of exposure and urinary phenol levels (p=0.305). Workers are advised to consistently use full personal protective equipment and practice good personal hygiene to minimize benzene exposure in the workplace.
