Air quality in Palangka Raya, the capital of Central Kalimantan province in Indonesia, has deteriorated to hazardous levels due to widespread forest and land fires, according to local authorities. The situation was confirmed on Friday after measurements taken by the Meteorology, Climatology, and Geophysics Agency (BMKG) indicated that particulate matter concentrations had exceeded safe thresholds. At 5 a.m. local time, the PM2.5 reading stood at 258.9 micrograms per cubic meter, climbing further to 290.2 at 6 a.m. These figures place the air quality firmly within the hazardous category, posing serious risks to human health. City official Samsul Rizal cited data from the Palangka Raya Disaster Agency, which noted that air quality varied throughout the day, fluctuating between moderate and hazardous levels. From 7 a.m. to 2 p.m., the PM2.5 levels dropped significantly, ranging from 236.3 at 7 a.m. to 68.7 at 11 a.m. However, this improvement did not eliminate the overall threat posed by the ongoing fires. Rizal emphasized that the impact of these fires extends beyond environmental concerns, affecting public health, visibility, and daily operations such as transportation. The vulnerability of Palangka Raya to severe fire-related pollution stems largely from its geographical composition. Much of the region is covered by peatlands, which burn more intensely and produce denser smoke compared to regular forest fires. This makes controlling the spread of fires extremely challenging and increases the risk of prolonged exposure to harmful pollutants. According to the Palangka Raya Disaster Agency, there were 298 recorded instances of forest and land fires between June 1 and August 19, 2026. These fires consumed approximately 261.41 hectares of land across multiple subdistricts. The majority of these incidents occurred in Jekan Raya, which accounted for 188 fires, followed by Sabangau with 68, Pahandut with 25, and Bukit Batu with eight. Rakumpit subdistrict reported no fires during this period. Muhammad Heri Pauzi, head of prevention and preparedness at the disaster agency, highlighted the geographic distribution of the fires, noting that Jekan Raya bore the brunt of the activity. He reiterated the importance of community involvement in monitoring and reporting potential fire hazards, stressing that collective efforts are essential in mitigating the effects of such disasters. Authorities have called upon residents, businesses, customary leaders, and community officials to remain vigilant and promptly report any signs of uncontrolled burning. Samsul Rizal warned that negligence or intentional acts of arson could lead to far-reaching consequences, emphasizing the need for public cooperation in preventing future occurrences. The current crisis follows similar episodes earlier in the year, including a period in early August when thick haze already pushed air quality into the hazardous category. This recurring pattern underscores the persistent challenge faced by local authorities in managing fire outbreaks, especially given the region's susceptibility to peatland combustion. As the situation continues to unfold, local officials are likely to intensify their efforts in both firefighting and public awareness campaigns. With the recent data indicating a high frequency of fires over the past few months, the focus will remain on preventing further escalation and ensuring the safety of the population exposed to hazardous air conditions.
