Land and forest fires is a familiar phenomenon in some parts of Indonesia, particularly Sumatera and Kalimantan Island. This phenomenon developes into a form of disasters that has an impact on people's life. Catastrophic events smoke caused by forest fires happened several times in Indonesia. Smoke could influence very negative impact on public health such as Acute Respiratory Infection (ARI) and pneumonia. The purpose of research conducted in 2011 was to analyse the impact of forest fires on the incidence of ARI and pneumonia in Pulang Pisau, Central Kalimantan. Using a cross-sectional study design, data analysis was done descriptively, to describe the trend of ARI and pneumonia during 2004-2011 in the district. The results showed that in Pulang Pisau District for seven years (2004-2011), the incidence of ARI was fluctuated in each year, but the highest in December, such as in 2005 and 2008 the incidence of ARI reached 21,65 per 1000 population and 35,58 per 1000 population respectively. The incidence of pneumonia among ≤ 5 years old varied, the highest incidence in 2004 occurred in March (0,35), 2006 in July (0,51), 2007 in March (0,55) and 2008 in January (0,42) respectively. The highest hotspot in 2004 occurred in October (962), 2005 in September (270) and 2011 in August (316) respectively. As a conclusion, the impact of smoke from forest fires on health could be respiratory infection especially for high risk groups. Probably, there was a relationship of ARI and pneumonia with quality of the air in the study area.
