Apa Penyebab Banjir Besar yang Bikin Bekasi Lumpuh? | Narasi Explains

Summary

The flooding in Bekasi on March 4, 2025, is one of the worst in recent years, with water levels reaching up to 2.5 meters. This flooding, affecting 20 locations across seven sub-districts, was caused by heavy rainfall on March 3. Beyond natural factors, urbanization and the destruction of green spaces, as shown by a 2013 study, have contributed to the worsening floods. The conversion of land for housing and industry along the Bekasi river has led to increased runoff, overwhelming the rivers. In addition, improper waste disposal into the river adds to the flooding risks, with Bekasi generating 775 tons of waste daily.

Takeaways

• 😀 The flood in Bekasi on March 4, 2025, is one of the worst in recent years, with water levels reaching 2.5 meters.
• 😀 The flood affected 20 locations across 7 subdistricts, caused by heavy rainfall on March 3, 2025.
• 😀 The flood was influenced by the Alang phenomenon, but other factors may also have contributed to the disaster.
• 😀 A major flood also occurred in Bekasi in January 2020, with water levels reaching 6 meters, resulting in 9 casualties and over 366,000 displaced people.
• 😀 Research from the Geospatial Information Agency in 2013 highlights land-use changes in the Bekasi watershed, particularly in the downstream and middle sections, as a cause of increased flood risk.
• 😀 The conversion of forests and green areas into housing, industrial zones, and golf courses has significantly worsened flood conditions by increasing surface runoff.
• 😀 Satellite imagery shows that the Bekasi riverbanks in the downstream area are winding, making them prone to flooding and erosion.
• 😀 Urbanization and the rising demand for housing have led developers to target cheap land near riverbanks, which should not be used for settlement purposes.
• 😀 The upper and middle reaches of the Bekasi river, particularly the Cikeas river, were once filled with natural vegetation like forests and grasslands that helped absorb rainfall, but they are now developed areas.
• 😀 The increased urbanization results in more water flowing directly into rivers, raising water volumes drastically and exacerbating downstream flooding.
• 😀 The research also identifies the problem of waste disposal along riverbanks, with significant amounts of garbage flowing into the river, further contributing to flooding. In 2019, a non-profit environmental organization reported that Bekasi could leak up to 775 tons of waste into rivers daily.

What is the primary cause of frequent flooding in Bekasi according to the 2013 study?

According to the 2013 study, the primary cause of frequent flooding in Bekasi is the widespread land-use changes in the Bekasi river basin, especially in the lower and middle sections.

How have land-use changes in Bekasi contributed to flooding?

Land-use changes, such as the conversion of forests and green spaces into residential and industrial areas, have increased surface runoff and reduced the land’s ability to absorb rainwater, leading to higher flood risks.

What role has urbanization played in the flooding of Bekasi?

Urbanization has driven developers to build in flood-prone areas near the riverbanks, which should not be used for settlement. This has worsened the flooding problem in Bekasi.

How has the disappearance of natural vegetation along the Bekasi river affected flooding?

The disappearance of natural vegetation, such as forests and grasslands, along the Bekasi river has led to reduced water absorption, causing rainwater to flow directly into the rivers and increasing the risk of flooding.

What impact has waste disposal into the Bekasi river had on flooding?

Waste disposal into the Bekasi river has exacerbated flooding by clogging the river system. In 2019, it was reported that 775 tons of waste were entering the rivers daily, contributing to blockages and increasing the severity of floods.
