Studi Karakteristik dan Wilayah Terdampak Banjir di Kecamatan Mandonga, Kota Kendari

Abstract

Karakteristik, Luas Genangan ABSTRACT The study aims to analyze the characteristics of floods that occurred in Mandong District, Kendari City, Southeast Sulawesi Province. The study used a qualitative descriptive design and survey. The object of analysis is flood classification (flash floods, inundation, and tidal flooding), inundation conditions (inundation height), and causes of flooding. Primary data was obtained in the field, while secondary data was obtained from various sources related to flood events in 2013-2018. This study involved 31 informants. Data were analyzed by quantitative descriptive and spatial analysis (GIS, namely ArcView 3.2). The results of the study showed that the floods that occurred in Mandonga District were classified as inundation floods. The height of the puddle is between 1-2 m, and the average inundation time is 1 day (during it rains). The cause is the accumulation of high rainfall, river, and poor drainage resulting in the generation of waste along the stream, as well as loss of water absorption due to construction activities (buildings). The area affected by flooding in Mandonga District is around 37.45% of the total area. It is spread across all sub-districts, with the largest area in Labibia Village around 29.10% of the total affected area (416.23 ha), followed by Wawombalata Village at around 23.01%, while the smallest is in Anggilowu Village
