Kajian Faktor Penyebab Terjadinya Banjir di Kelurahan Aur Kecamatan Medan Maimun

The recurring phenomenon of flooding in various parts of Indonesia, including Kelurahan Aur in Medan Maimun Sub-district, reflects the weak implementation of environmental policies despite being regulated in Law No. 32/2009 on Environmental Protection and Management. This research aims to comprehensively identify and analyse the factors that cause flooding in Kelurahan Aur through a qualitative approach based on field data. Data was collected through in-depth interviews and direct observation of the community and the surrounding environment, with the support of secondary data from relevant literature. The results show that flooding in Kelurahan Aur is caused by the interaction between internal and external factors, such as environmentally unfriendly community behaviour, population density without good spatial management, and inadequate drainage infrastructure. On the other hand, environmental degradation in upstream areas, uncontrolled urbanisation, and global climate change also exacerbate the intensity and frequency of flooding. In addition to the physical aspects, low public awareness and participation in environmental management are the main obstacles to flood mitigation efforts.
