Jakarta – Several cities in Central and West Java have been struggling to put out fires engulfing their landfills, with fires triggered by the hot temperature of this year's prolonged, El Nino-induced dry season.
The Putri Cempo landfill in Surakarta, Central Java was the latest, with the fire first breaking out on Saturday. It has so far burned 2 ha of the mountains of trash.
Authorities suspect that the fire was triggered by the high temperatures experienced during the prolonged dry weather.
The Central Java weather station previously issued a drought warning for several cities and regencies in the province, including Surakarta.
"Our analysis for now shows that the high temperature sparked the methane gas formed by the mountain of trash," said Surakarta Environment Agency head Kristiana Hariyanti, as quoted by kompas.com.
Methane, a flammable gas, is often found in landfill sites as the natural by-product of the decomposition of organic waste, according to the United States Environmental Protection Agency (EPA).
Firefighters are still struggling to put out the fire in the 17 ha landfill.
Changing wind directions and the vast pile of flammable waste have caused the fire to spread quickly, hindering the extinguishing efforts, according to the National Disaster Mitigation Agency (BNPB).
A total of 45 firefighter units from various local disaster mitigation and fire agencies around Surakarta had been deployed as of Monday to Putri Cempo.
"We also have received a request from the Surakarta municipality administration for a waterbombing operation to put out the fire in the landfill," BNPB emergency management deputy Fajar Setyawan said on Monday in a statement.
The fire in Putri Cempo has caused a haze over several residential areas around the landfill.
Around 200 residents in Mojosongo subdistrict have complained about health issues felt by vulnerable groups, including respiratory problems affecting children and elderly people, according to the Surakarta Disaster Mitigation Agency.
Health workers from Mojosongo administration have provided treatment for the affected residents.
Local authorities have also distributed face masks and advised residents living around 50m from the landfill to evacuate, although most decided to stay home.
Reduced waste capacity
The Putri Cempo fire is among the latest incidents hitting landfills across Java. A fire also broke out at the Jatibarang landfill in Semarang, Central Java on Monday.
Authorities are still investigating what caused the fire, but strong winds caused it to spread to another area of the landfill, the Antara news agency reported. Firefighters had put out the fire as of Tuesday.
However, they were still spraying water on sections of the landfill to prevent the waste from being reignited due to the high concentration of methane in the trash.
Acting Central Java Governor Nana Sudjana had requested BNPB's help to deploy a waterbombing helicopter in Jatibarang to prevent further fires from breaking out.
"The helicopter will waterbomb Jatibarang after it's done its job in Surakarta," Semarang Mayor Hevearita Gunaryanti Rahayu said on Tuesday, as quoted by Antara.
Two landfill sites in neighbouring West Java had also caught fire. A fire burned around 3 ha of Kopi Luhur landfill in Cirebon on Sept 9.
While firefighters quickly put out the fire, the haze created by the smoke forced 1,500 households residing around the landfill to evacuate for several days.
Authorities previously also struggled to put out a fire engulfing Sarimukti landfill in West Bandung regency, which has burned at least 20 ha of the landfill since Aug 19.
Acting West Java Governor Bey Machmudin said on Tuesday that firefighters were still struggling to put out the "20 per cent of fire left" in the landfill.
The acting governor also said the landfill would only be able to store 50 per cent of its original waste capacity once all the fire was extinguished to prevent a similar incident from occurring, as reported by tribunnews.com.
The 25 ha landfill used to be a waste hub for Bandung and its surrounding cities, storing about 80 per cent of the 1,500 tonnes of waste generated daily by the city.
Blaming El Nino
Indonesia is expecting to see more fires during 2023's dry season, which is expected to be longer and drier due to the El Nino weather system, where the Pacific Ocean is warm for an extended period that tends to bring hotter air over the Indonesian archipelago.
The El Nino system is expected to peak this month, according to the Meteorology, Climatology and Geophysics Agency (BMKG).
Some regions are struggling with the rise of forest and land fires that are causing a haze to blanket large parts of the province, such as Palembang in South Sumatra.
The country has seen more than 90,000 ha of land burned between January and July, according to data from the Environment and Forestry Ministry.
