Pemetaan Tingkat Rawan Bencana Banjir di Daerah Aliran Sungai Maros Provinsi Sulawesi Selatan

Abstract

Indonesia is an archipelago with a tropical climate with very high rainfall. In the rainy season floods occur which cause losses, namely loss of life and property. This condition is a routine disaster that always threatens people's lives. Therefore, research needs to be done to identify flood-prone areas and flood-causing factors in the Maros River Basin. The method used to determine flood-prone areas is used by a combination of remote sensing, terrestrial, secondary data and interviews using the criteria of Sutikno et al (1995) with development. The variables used topography (flat and sloping), soil texture, drainage, inundation time and flood return period. The analysis shows that in the Maros watershed there are 3 classes that are prone to flooding namely not prone, prone and very prone. Most are vulnerable because more than 50 percent of the area is at a vulnerable and very vulnerable level. The class is very prone to spread from downstream to the middle of the watershed, covering the southern sub-districts of Maros Baru, Marusu, Turikale, southern Bantimurung, western Simbang, northern Mandai and northern Tanralili. The contributing factors are high rainfall, flat and sloping topography, fine soil texture in the downstream river, poor drainage due to poor waste management, land use dominated by ponds and paddy fields and high flood return periods.

Ketahanan Masyarakat Dalam Menghadapi Bencana Banjir Di Kecamatan Maros Baru Kabupaten Maros

“…Di wilayah Kabupaten Maros terdapat DAS besar yaitu Daerah Aliran Sungai Maros yang melewati ibu kota Kabupaten Maros dan sekaligus jalur lintas provinsi Sulawesi Selatan. Wilayah DAS Maros sebagai besar kelas kemiringa lerengnya seluas 23.932,76 Ha atau 36,26 persen, yang landai 18.442, 60% (Badwi, Invanni, & Abbas, 2020). Jadi 50% dengan kemiringan datar dan landai, sehingga peluang banjirnya tinggi, Daerah yang datar tersebar dibagian Hilir DAS hingga tengah, dan yang landai dari tengah hulu tersebar tidak merata.…”

Disaster education as an effort to improve students' flood mitigation preparedness

“…One of the reasons is that schools hold outreach and introduce online-based applications as a reminder when a disaster occurs. However, the study of community disaster preparedness in anticipating disasters by mobilizing student resources is still low, which can be seen from the small proportion of students who have participated in various disaster preparedness activities (Badwi, Invanni, & Abbas, 2020).…”

Proyeksi Daerah Potensi Banjir Tahun 2031-2040 Berdasarkan Skenario Iklim Representative Concentration Pathways 4.5

“…Upaya mengatasi masalah banjir di Indonesia telah dilakukan sejak tahun 1920-an baik oleh masyarakat yang terkena bencana maupun pemerintah. Banjir sendiri tidak menjadi masalah selama tidak mempengaruhi aktivitas atau keuntungan manusia, terjadi setelah manusia melakukan aktivitas di dataran banjir (Arfan et al, 2020;Badwi et al, 2020). Pengelolaan bencana banjir yang efektif dan efisien memerlukan pengetahuan tentang bahaya dan risiko yang ada di daerah aliran sungai seperti Sungai Begawan Solo.…”
