JAKARTA: A fire at Pertamina's refinery complex in Cilacap, central Java, was under control and being gradually extinguished, the Indonesian energy company said early on Sunday.
The fire started around 1920 (1220 GMT) on Saturday at a fuel storage unit, and amateur videos broadcast by local media showed a large blaze colouring the sky orange.
The fire affected one of 228 storage tanks in the Cilacap refinery complex, and Pertamina said it was still working to completely put out the fire.
"Even though it has been successfully controlled, we are still carrying out insulation around the tank as well as cooling it with fire trucks and hydrants so that the fire is completely extinguished," Ifki Sukarya, a Pertamina spokesperson, said.
Around 80 people living nearby who were evacuated overnight have returned home, Ifki said.
Cilacap is one of Pertamina's biggest refining facilities and supplies around 34% of national fuel demand, the Pertamina website said.
Pertamina ensured that fuel supply and distribution processes were not disrupted, it added in the statement.
