Abstract

Flood is an annual disaster that hits all over Indonesia, and Magetan Regency is one of the affected area . The high regional topography in the western part and the relatively flat topography in the eastern part making it potential for flood to be higher in the eastern part. The DEM (Digital Elevation Model) topography, Landsat maps, and hazard index maps can be identified by remote sensing using regional administration map data, the level of slope slope and vegetation density can be mapped using NDVI method, and the classification of the flood risk level of an area can be done using ArcGIS software. The slope of the slope and the density of vegetation will affect the level of potential flood hazard. There is a low level of potential for flooding on steep slopes because the air will flow and accumulate on the lower plains. Higher vegetation density will provide a good air catchment area. The level of vegetation density is also higher in the western part. Based on the percentage of the affected area, the low flood hazard level reaches 73.3%, so it can be concluded that the flood hazard level in Magetan Regency is low. It is necessary to provide adequate land and channels capable of providing air flow.

Abstract

Pacitan Regency is one of the tourist destinations in East Java due to the beauty of tourism from the caves to the beaches that stretch along the southern part of Pacitan. Apart from tourism potential, Pacitan Regency, which borders the Indian Ocean in the south, has the potential to be hit by a tsunami wave that occurs due to the collision of the Eurasian and Indo-Australian plates. By using a remote sensing method, it can be seen how the tsunami hazard level of an area is based on the parameters of the slope, the height of the area, and the distance from the coastline. In addition, the level of exposure of the population is also a factor in determining the level of tsunami hazard. In Pacitan Regency, the area affected by the low level tsunami reached 33753 Hectare, the medium level was 13498 Hectare, and the high level was 3828 Hectare. Areas with a high level of danger are located along the coast which extends in the southern part of Pacitan Regency. The area with the highest level of danger with a wider coverage is around Pacitan Bay. Therefore, it is necessary to have an appropriate mitigation system in reducing the risk of tsunamis, especially around the coast which is used as a tourist destination.
