Abstract

Kabupaten Bondowoso merupakan daerah yang rawan terhadap bencana banjir. Banjir dapat terjadi akibat adanya genangan air pada suatu daerah dalam kurun waktu tertentu. Penggundulan hutan oleh masyarakat sekitar menjadi salah satu faktor pendukung yang dapat menyebabkan bencana banjir. Melihat hal tersebut maka salah satu upaya untuk dapat mengelola resiko terjadinya bencana banjir adalah dengan menentukan daerah-daerah yang rawan terhadap banjir yang terjadi di Kabupaten Bondowoso terutama di Sub DAS Wonosari. Beberapa parameter yang mempengaruhi tingkat kerawanan banjir disuatu daerah, diantaranya parameter curah hujan, jenis tanah, penggunaan lahan, kemiringan lahan, limpasan permukaan, ketinggian lahan dan kerapatan sungai. Parameter-parameter tersebut diolah dengan pembobotan dan skoring yang kemudian di overlay untuk mendapatkan peta rawan banjir. Terdapat 5 kelas kerawanan banjir yaitu sangat rendah, rendah, sedang, tinggi dan sangat tinggi. Hasil penelitian menunjukkan bahwa daerah rawan banjir pada lokasi penelitian paling signifikan berada ditingkat tinggi dengan luas sebesar 281 km² atau 44% dari total luas Sub DAS.

Abstract

Bondowoso Regency is known as a region highly susceptible to flood disasters. Factors contributing to the increased flood risk include the hydrological and topographical conditions present in the study area. Therefore, it is essential to identify and map areas that are vulnerable to flooding. Flood vulnerability is influenced by several parameters, including rainfall, soil type, land use, slope gradient, surface runoff, and elevation. The data used in this study were obtained from UPT PSDA WS Sampean, covering the period from 2013 to 2023. These parameters were processed using a weighting and scoring method. The assignment of scores and weights was based on the influence of each parameter on flood vulnerability, with each parameter assigned an equal value ranging from 1 to 5. An overlay analysis was then performed to generate a flood vulnerability map. The resulting vulnerability levels were classified into five categories: very low, low, moderate, high, and very high. The results show that the majority of flood-prone areas fall within the "high" vulnerability category, covering approximately 250.18 km² or about 41% of the total area of the Wonosari Sub-watershed. This finding can be validated by historical events in 2023, during which several flash floods were recorded.
