ilica dust exposure has long been known as risk factor for tuberculosis. Therefore, the risk of silica dust exposure can be an asset for health promotion to eradicate tuberculosis at workplace. The study design as case-control study with cases (129 persons) and control (129 persons) matched by age with 5-year interval, and gender. History of occupation with silica dust exposure was taken by interview using questionnaire. Secondary data on diagnosis of tuberculosis which are acid-fast bacilli sputum smear and thorax photo interpretation were taken from the register of TB-03 at each health centre. Bivariate analysis shows that moderate to high silica dust exposure has crude OR=11.05 (95% CI = 1.39-87.69, p=0.023). Meanwhile, multivariate analysis does not show its effect towards pulmonary TB. Factors that increases risk are education, low income, low body mass index (BMI), and moderate-heavy drinking. Effect of occupation with silica dust exposure on pulmonary TB was not shown in this study. Limitation of the study population was assumed as one of the cause. Further research is needed to be done in more specific population such as community of worker in industry with silica dust.
