LAJU TRANSPOR MUKOSILIAR MUKOSA NASAL PADA PETUGAS SPBU

Abstract

Background : Fuel vapor contains benzene, toluene, ethylbenzene, xylene (BTEX) which are irritant substances. Exposure to irritants in the nasal mucosa will cause damage to the nasal mucociliary transport system. Gas station officers in Indonesia are exposed to the irritant substances during their employment. The effect of working as a gas station operator and the duration of work on the nasal mucociliary transport system is not yet known. Aim : Knowing the difference between nasal mucociliary transport time with a job as a gas station operator and duration of work. Methods : This study was an observational study with age matched case control design. Samples were 18 gas station officers around Tembalang Semarang and 18 students and officials at FK Undip Tembalang Semarang as the control group. Nasal mucociliary transport times were measured using saccharin test. Normality of the data was tested by the Shapiro-Wilk. Data were analyzed with the Mann-Whitney test. Results : The mean nasal mucociliary transport time on gas station officers was 1222.56 seconds while on non gas station officers was 892.33 seconds. The Mann-Whitney test nasal mucociliary transport time on officers and non officers showed a significant difference (p = 0.001), whereas there was no significant difference (p = 0.075) when compared to the duration of work. Conclusion : There is a time difference of nasal mucociliary transport on gas station officers and there is no difference compared to the duration of work. Key Words : Fuel vapor, nasal mucociliary transport time, job, duration of work
