Peran Infrastruktur Biru Low Impact Development dalam Meningkatkan Ketangguhan Wilayah Perdesaan terhadap Genangan Banjir

Abstrak

Recurring flooding in rural areas, particularly in Lakawoghe Village, West Muna Regency, is often exacerbated by conventional rainwater management systems that focus on accelerating runoff and ignore local hydrological processes. Over the past seven years, this village has experienced consistent flooding, highlighting the need for more adaptive and sustainable runoff management strategies. This study analyses the role of Low Impact Development (LID)-based Blue Infrastructure in improving the resilience of rural areas to flooding. A quantitative approach combined with spatial analysis was used to compare existing conditions and simulate the application of LID in priority flooding areas. The results show that the integration of bioretention units and infiltration wells can reduce runoff volume from 581,825.02 m³ to 581,734.42 m³ during a five-minute rainfall event, with a reduction rate of 1,939.11 m³ per second. Although the reduction in runoff is relatively small on a watershed scale, LID interventions significantly reduce local hydrological pressure and flooding intensity and serve as a strategy to increase the adaptive capacity of rural areas to recurrent flooding.
