Background The prevalence of smokers in Indonesia is increasing. With the majority of smokers admitting that they smoke inside buildings, Smoke-free Areas should be enforced in order to protect non-smokers from becoming passive smokers. Aim To what extend do SFA is trully a smoke-free and to what extend do local/mayor regulation have an impact on reducing the violation of SFA. Method This is a survey of eight categorized areas in the Daerah Istimewa Yogyakarta (DIY) province that are considered as SFA according to SHealth Law Number 36 / 2009. The survey, which covered all five regions (kabupaten/kota), was conducted in April 2016. This study uses two stages of sampling method. The first stage of the survey was randomly choosing the kecamatan (district) and the second stage was randomly choosing the areas within district. There were 547 areas in total. Result The findings of this study show that there is a high percentage of smokers or trace of smoker found in office areas (67%), play parks (69%), and public places (80%). This violation of SFA in Kota Yogyakarta, Kulon Progo, or Gunung Kidul were found in 74%, 64%, and 37% of locations respectively. These three regions have regional SFA law . Whilst in Bantul and Sleman, the survey found violations in 52% and 51% of locations respectively. Another violation type according to the law are the selling points of tobacco products and tobacco advertisement mostly found in public areas. The highest percentage of this violation was found in Kota Yogyakarta and the second highest was in Gunung Kidul. Conclusion These findings suggest that in general, the SFA violation is high and found in all areas, even those with established local law. An implication of this study shows that a non-smoker most likely becomes a passive smoker, either when they are inside an office or in public spaces. The worst part is, it has become dangerous for children playing in play ground since they will be exposed to the smokers' smoke.
