Workers of NPK production section in PT. Petrokimia Gresik have high risk from dust deposition on their respiratory tract. This research purpose to analize the exposure of dust and lung function disorder on workers of NPK production section PT. Petrokimia Gresik, in Gresik Regency. This research was an observational research with a cross cectional design and 30 samples were taken. Sampling was carried out by using a purposive sampling technique. Data of respirable dust concentration measured by personal dust sampler, whereas data of lung function was taken by Spirometer. Data were analyzed by chi-square technique. Result of the research showed that dust grade of concentration collected by device High Volume Sampler (HVS) devices at PT. Petrokimia Gresik NPK production section of two site in crusher section was measured 2,0597 mg/m3 and in packaging section was measured 1,4562 mg/m3. Result of dust concentration showed that dust on this location was still under the National Threshold Value, although it right give an edverse effect for workers. Result of respirable dust grade showes National Threshold Value of above and average value 1,136 mg/m3. Average value %FEV1/%FVC to workers 86,15%. The result of the research showed that factors which were related to the lung function disorder were exposure to respirable dust (p=0,020). It can be concluded that there were relationship between exposure respirable dust and lung function disorder.
