Abstract

Adaptation of the community to flood natural disasters is part of the flood mitigation natural disaster that often occurs in the rainy season. The aims of this research is to analyze landform units and land characteristics that have flood hazards and community adaptation strategies in dealing with flood natural disasters. The method used in this research is the survey method, which is to collect data on land characteristics as characteristics or characteristics of flooded areas and interviews with local communities about adaptation strategies undertaken to deal with flood natural disasters. The results showed that the landform units formed due to the flood process in the study area were in the form of floodplains, back swamps, alluvial terraces, depression inter beach ridge, and alluvial plain complexes. The unit characteristics of landforms generally have flat morphometry with slopes ranging from 0 - 2%, the genesis of these landform units due to fluvial and marin processes. The constituent material in this area is mud to coarse sand. The rock conditions in this area are rocks originating from volcanoes and undergoing a process of destruction due to processes from the river so that the rocks in this area are gravel, rough sand, fine sand. Soil conditions in each unit of landform also vary from the formation of soil to on newly developed land. Vegetation that grows in each unit landform of this is in the form of natural vegetation and lovely water vegetation or vegetation which requires a lot of water for its growth and development. The community strategy in dealing with flood natural disasters is in the form of staging houses, knowing the time of occurrence of tides, and opening the river estuary if the river estuary is covered by sediment.

Abstract

The article on models of land use change and land cover in Koto XI Tarusan District, Pesisir Selatan Regency, West Sumatra aims to model changes in land use and land cover in Koto XI Tarusan District, Pesisr Selatan Regency, and to find out the accuracy of the results of modeling changes in land use and land cover 2025 and 2030.The method used in this research is quantitative method using remote sensing data in the form of 2000 Landsat 5 images, 2009 Landsat 7 images, and 2019 Landsat 8 OLI images. The driving force used in this study is the distance from the road, the government center, health facilities, educational facilities, slopes, and elevations.The results showed that the results of modeling changes in land use and land cover in 2025 and 2030 indicated that there were changes in land cover of primary forest, secondary forest and mixed orchard. Land uses that have increased aruilt up area, and oil palm. The results of modeling accuracy test using the overall accuracy obtained in 2025 accuracy is 92.50 % and in 2030 is 89.75%. The accuracy results show that the modeling results have been very good.
