THE EFFECT OF NOISE ON WORKER CONCENTRATION AT SULTAN ISKANDAR MUDA INTERNATIONAL AIRPORT, ACEH BESAR REGENCY

Noise is a common physical hazard in the workplace. Exposure to high-intensity noise, exceeding the threshold limit value, can lead to various health problems such as hearing impairment and a decline in concentration. Sultan Iskandar Muda International Airport experiences significant noise levels, primarily from aircraft movements on the runway, with engine noise during landing and takeoff reaching 110–120 dBA. This study aims to determine the effect of noise on worker concentration at Sultan Iskandar Muda International Airport. This was an analytical survey with a cross-sectional study design, conducted on February 20, 2024. The sample consisted of 30 workers from four external locations within the airport: Aviation Security, Apron Movement Control, Aviobridge Operator, and Ground Handling. Data analysis was performed using the Chi-Square statistical test. The study found that the noise levels at the four measurement points were within the permissible limits, with an average noise level of 85.9 dBA. Furthermore, the workers' concentration was also categorized as good, with a score of 80%. The Chi-Square statistical test revealed no significant effect of noise on worker concentration. It can be concluded that noise is not a significant variable affecting worker concentration at Sultan Iskandar Muda International Airport in Aceh Besar Regency in 2024. Worker concentration may be influenced by other variables, such as external factors, age, and years of service. It is recommended that workers are educated on methods to maintain concentration in noisy environments.
