Massive floods in Southeast Asia are one of the natural disasters that have shaken the lives of people in this region. Every year, continuous heavy rains during the rainy season cause rivers to overflow, inundating residential areas and agricultural land. Countries such as Indonesia, Malaysia, Thailand and the Philippines often become emergency zones due to prolonged flooding. The impact of major floods is extensive and destructive. Infrastructure such as roads, bridges and public buildings is often destroyed, making access to aid and community mobility difficult. In Indonesia, for example, floods that hit Jakarta in early 2023 killed dozens of people and forced thousands of residents to flee. In addition, the resulting economic losses could reach billions of dollars, disrupting local and national economies. Floods not only destroy physical infrastructure but also impact public health. Polluted cloudy water can spread diseases, such as diarrhea and leptospirosis. Health centers are overwhelmed with the surge in patients exposed to water-related illnesses. Empowering communities to maintain cleanliness and health after a disaster is very important to prevent epidemics. Climate change also plays a major role in the intensity and frequency of floods in Southeast Asia. Global warming causes an increase in extreme rainfall, resulting in more frequent disasters. Communities must adapt to these conditions, through education about risk mitigation and emergency management. Efforts to plant trees to increase water absorption also need to be increased to minimize the impact of flooding. In addition, an effective early warning system is crucial in preventing further losses due to flooding. Research shows that people who have access to accurate information about weather and potential flooding can act more quickly to protect themselves and their property. Therefore, investment in information and communication technology is very important in dealing with flood risks. Drainage infrastructure also needs to be repaired and expanded to accommodate overflow water during the rainy season. In several large cities, infrastructure projects to address flooding have been launched, but many of them are hampered by budget problems and corruption. With transparent planning and implementation, it is hoped that flooding problems can be minimized. Community participation in disaster risk management also shows positive results. In a number of areas, local communities have taken the initiative to build retention ponds and clean water channels to reduce overflow. This kind of initiative is very effective and can be an example for other areas affected by flooding. The government and non-government organizations need to work together to strengthen the post-flood emergency response and rehabilitation system. Using ecosystem-based approaches, such as wetland restoration and reforestation, can help reduce the risk of future disasters. This approach can also increase food security, considering that many areas affected by flooding are agricultural centers. In closing, major floods in Southeast Asia are a complex challenge that requires cooperation from all sectors. Society, government and the private sector must come together to create sustainable solutions. Education, innovation and public awareness will be the key to overcoming the impact of recurring floods.
