In flood-prone areas, coordination between parties in disaster risk reduction activities is very important. This is because disasters will directly impact the disruption of people’s lives and livelihoods, as well as hinder the process of sustainable development. This study aims to develop a public coordination scheme for flood risk reduction activities based on public resources available in North Luwu Regency. Public resources come from government agencies and the potential of the community available in North Luwu Regency with their respective tasks at the stage before, during, and after the disaster. Public coordination is expected to support the implementation of sustainable development based on disaster risk reduction in North Luwu Regency. The preparation of the public coordination scheme was preceded by a geospatial flood hazard assessment based on the characteristics of the Rongkong Downstream Watershed using a Geographic Information System (GIS). The results of the assessment form the basis for the implementation of the preparation of public coordination for DRR. North Luwu Regency is dominated by coastal land units bordering Bone Bay, plains to mountains. High rainfall, critical land use, and low-lying settlements cause the research area to be in a high to very high risk zone experiencing flooding. Sustainable development can run effectively if its implementation is based on disaster risk reduction policies with public coordination. Public coordination is carried out between government agencies and the community, who work together according to their respective roles and tasks at the pre-, during, and post-disaster stages. The results of the study indicate that more sector involvement is needed in the pre-and post-disaster stages. This indicates that public coordination before a disaster is risk prevention and reduction activity that should be prioritized in the implementation of development before hampering the sustainability of development.

This research is important to do to improve flood disaster management in the Walanae Watershed, with the aim of researching and analyzing the most effective appropriate land use to reduce the risk of flooding and damage. This research was carried out in the Walanae Watershed, Dua Boccoe District, Bone Regency, South Sulawesi Province. Appropriate land use that is most effective in reducing the risk of flooding and damage is analyzed descriptively qualitatively with the Overlay approach. Assuming that the process produces data from the findings in the form of field observations. The impact of appropriate land use that is most effective in reducing the risk of flooding and damage is measured using the basic physical condition analysis method, this superimpose analysis is used to determine flood-prone areas based on several aspects and a qualitative descriptive analysis will clearly describe the impacts that have been caused by floods. The results showed that there are 8 sub-districts/villages that have the potential for flooding, including Unyi Village, Uloe Village, Pekkasalo Village, Kampoti Village, Tocina Village, Tawaroe Village, Solo Village, and Matajang Village. With an area of 131 km2, and an existing inundation height of ±100–200 cm and an inundation period of 10 hours, Dua Boccoe Subdistrict has the potential to be affected by flooding. Floods in Dua Boccoe Subdistrict are caused by internal factors: Topography, Drainage Infrastructure, Building Density, and Land Use and others as well as external factors: Topography, and Shipment Floods.
