REPUBLIKA.CO.ID, JAKARTA -- The Center of Economic and Law Studies (Celios) conducted a study analyzing the economic impact of the recent floods that struck various regions across Sumatra. The study found that the disasters caused economic losses exceeding Rp 68 trillion.

“The ecological disaster in Sumatra during November 2025 is projected to have resulted in economic losses amounting to Rp 68.67 trillion. This figure includes damage to homes, loss of household income, destruction of road and bridge infrastructure, and reduced agricultural output due to inundated farmland and landslides,” Celios Executive Director Bhima Yudhistira said in the study titled “Economic Loss Impact of Sumatra Floods”, quoted Tuesday (2/12/2025).

Specifically, the projected losses are Rp 2.04 trillion in Aceh Province, Rp 2.07 trillion in North Sumatra, and Rp 2.01 trillion in West Sumatra.

Bhima explained that the economic loss estimate is based on five categories of damage: residential losses, calculated at Rp 30 million per house; bridge losses, with reconstruction costs estimated at Rp 1 billion per bridge; loss of family income, calculated using each province’s average daily income multiplied by 20 working days; losses in rice fields at Rp 6,500 per kilogram, assuming a yield of seven tons per hectare; and road repairs, estimated at Rp 100 million per 1,000 meters.

Celios stated that the disaster in Sumatra was an ecological disaster driven by land degradation caused by palm oil deforestation and mining activities. According to the survey, regions with a strong mining sector show a higher risk of ecological disasters compared to areas without mining operations.
