The analytical design was used in the study with cross sectional approach. The subjects of the research were the active students and the employees of the Medicine Faculty, Muhammadiyah University of Surakarta. The sampling method was the purposive random sampling.

The number of FVC samples is 42 people, consists of 50% of smokers and 50% non smokers. There was different of FVC between smokers and nonsmokers, with p= 0.000. The FVC of smokers is 2,722.86 ml and 3,528.57 for nonsmokers.
