Abstract
Background: Batik is a high artistic craft and a part of Indonesian culture especially in Java that using heating wax as the main component of production process. This study aimed to determine the exposure effects of smoke wax (malam) batik for lung function and occupational asthma in traditional batik industry workers. Methods: An observational analytical study with cross-sectional design is perfomed in traditional batik industry, Kampung Batik Surakarta Laweyan February to April 2008. Totally 44 subjects consisted of 22 people exposed group and 22 people unexposed group to batik wax vapour. Results: No significant relationship was found between exposure of batik smoke wax in decreasing lung function (X2=2.03, p=0.154). Exposed group had a risk 4.67 times of lung dysfunction than the unexposed group (OR=4.67; 95% CI 0.48 to 45.62). Significant differences in average FVC (t=2.49, p=0.017) and FEV1 (t=2.42, p=0.020). Impaired lung function workers have a longer duration of action statistically significant (t=2.75, p=0.009). There was a significant association between exposure of batik smoke wax with clinical symptoms (OR=12; 95% CI 1.35 to 106.80), (χ²=6.84, p=0.009). Batik wax smoke exposure didn’t pose a significant impact on the incidence of occupational asthma and the effect is weak (OR=1.03; IK95% 0.87 to 1.05), (χ²=1.02, p=0.312 ). Conclusion: There is a relationship between exposure to batik wax smoke and lung function impairment and clinical symptoms, but no correlation with the occupational asthma.
