Objective: Traffic police officers are group of workers prone to develop Acute Respiratory Tract Infection (ARTI) due to their risky working environment and non-compliance personal protective equipment application. Method: Cross-sectional research method using Chi-squared test is used to identify the relationship between work environment and self-protection application to the occurrence of ARTI. This study used a simple random sampling method involving 71 participants. The instruments used in this research are work environment questionnaire, self-protection application compliance, and the occurrence of Acute Respiratory Tract Infection questionnaire. Results: The result showed that 52.1% of the police officers have a risky working environment, 53.5% of them didn't have a compliance behavior on using personal protective equipment, and 50.7% of them reported the ARTI occurrence. The analysis result using chi-squared showed that there was a significant relationship between working environment and the occurrence of ARTI (p=0,024), as well as there was a significant relationship between the application of self-protection equipment (P=0,001). Traffic police officers working on a risky working environment have 3.385 times bigger chance to develop ARTI and the police officers who are obedient on using the personal protection equipment have 6.545 times bigger chance not to develop ARTI. Conclusion: The implication of this research is that nursing service institutions are able to coordinate with related institution having health education program related to their health problem that may occur due to their working environment and worker’s self-protection application.
