ABSTRAKScope and Research method : In order to find out the prevalence rate of respiratory obstruction due to exposure to jute's dust and other risk factors, such as work place, age group, length of work, smoking habit, usage of personal protection device, clinical symptom and allergy history, a cross sectional study regarding the influence of jute's dust on lung function among jute factory worker has been done in Tangerang. Total sample of respondent for this study is 135 workers, who are working in 4 working unit in the factory. There are 4 methods of data collection used in this study. First, interview by using Pneumomobile Project Indonesia questioner. Second, physical examination to all employees especially related to respiratory disorder. Third, measurement of lung function using spirometer. Fourth, examination of jute's dust at work place used low volume dust sampler.
Result and Conclusion: This study find out the concentration of total jute's dust in high exposure working place is 13,3mg/m3, while in low exposure working place is 1,5 mg/m3. Result of statistic soon significant different (p<0,05). The study also finds out that the prevalence rate of chronic respiratory obstruction among the workers who work in high concentration dust environment is 25,9% and with low exposure is 2,8%. Statistically it is significantly different (p<0,05). There are a significant relationship between occurrence of chronic respiratory obstruction disease and dust concentration, while there are no relationship with age group, length of work, education level, height of body, smoking habit, use of personal protection device, previous clinical symptom and allergy history. The prevalence rate of acute respiratory obstruction among the workers who work in high concentration dust environment is 11,1%, while in low concentration dust environment is 3,7%. Statistically has not significantly different (p0,05). There are no relationship between acute respiratory obstruction disease and work place, age group, length of work, educational level, height of body, smoking habit, use of personal protection device, previous clinical symptom and allergic history. Analysis of smoking habit as risk factor and its relationship with obstruction can't be done since the prevalence rate of smoking habit among the workers is low (1,5%).
