Abstract

The geographical condition of Ambon City, which is 75% a hilly area resulted in most communities building in marbled areas with slopes above 20%, which has the potential to threaten life and landslide disasters. This study simply looked at the influence of slopes and slope shapes in Ambon City that can be analyzed using geographic information systems (GIS) to map areas that have the potential for landslides. Identification and mapping of potential landslide areas have an important role as an effort in overcoming and anticipating the occurrence of landslide disasters. This study aimed to analyze the spread of potential landslide areas in Ambon City based on the results of SMORPH modeling. The study used the slope morphology or SMORPH method, which has a better degree of accuracy than the Storie Index and SINMAP methods to identify and classify potential landslide areas based on the matrix between slope shape and slope angle. This study resulted in 4 levels of landslide potential areas, namely very low, low, medium and high potential. Areas with high landslide potential dominate the northern and southern parts of Ambon City. In the region, most landslides occur in the form of sunken and convex slopes. The region has a hilly and mountainous topography with a steep slope. The results of this research using the SMORPH method can illustrate that the slope of the increasingly higher slope accompanied by the shape of a convex or concave slope will cause the potential for landslides that are higher in the region.

Abstract

This study aimed to assess the erosion hazard level in the Wairutung Watershed. The land unit in this study was generated from the overlaying land use maps, slope maps, and soil types maps.  The class of vulnerability was determined based on the sum of the parameters' rating results using a computer-based Geographic Information System (GIS) with the ArcGIS program, which was integrated with the Universal Soil Loss Equation (USLE) model. The results indicated the division of 4 classes of landslide hazards consisting of a very light class with an area of ​​2,900.865 ha spread over land units with alluvial soil types. The medium type, with a total area of ​​3,683.285 ha, is spread over land units with podzolic soil types. Heavy type with a total area of ​​1,458.367 ha and the whole area is spread over land units with podzolic and Litosol soil types. The erosion hazard level is very heavy, with a total area of ​​421.97 ha and is spread over land units with Podzolic and Litosol soil types.
