Abstract
National Agency for Disaster Management (BNPB) noted since early 2017 to December 4th, 2017 recorded as many as 577 incidents of landslides throughout Indonesia. Based on Indonesia Disaster Information Data (DIBI) within 2017 until now in Wonosobo District there are 9 landslide events and one of them is in Wadaslintang Sub-District where causing fatalities and material loss. Many factors can cause landslides such as rainfall, slope, geological soil type and vegetation density, which is slopes are a major factor in some landslide disaster cases. Therefore, to anticipate the loss of both casualties and material losses more in Wonosobo Regency, it is necessary to conduct a study in order to obtain landslide potential areas. The model applied to determine landslide potential areas is the SMORPH model approach by implementing slope morphology and angle/gradient of the slopes using Geographic Information System (GIS). From the results of data processing found that the area of landslide potential with the highest grade in Wonosobo district of 17% area, and for sub-district and the sub-district with the highest potential landslide is Wadaslintang with the percentage of 13.85% area. Landslides can affect a variety of land uses, and the most widely affected is a plantation with 87,07 Km2
Highlights
Definition of disaster based on Law Number 24 of 2007 is an event or series of events that threaten and disrupt the life and livelihood of the community caused by both natural and/or non-natural factors and human factors resulting in the occurrence of human lives, damage environment, property loss, and psychological impact
Major factors that caused a landslide are nature condition and human activity. Nature condition such as Geology refers to material characteristics itself. morphology refers to the landscape structure of the earth
In this research to know the landslide potential area and what kind of land use got the impact from the landslide, used materials like Slope from Digital Elevation Model (DEM), and land use
Summary
Definition of disaster based on Law Number 24 of 2007 is an event or series of events that threaten and disrupt the life and livelihood of the community caused by both natural and/or non-natural factors and human factors resulting in the occurrence of human lives, damage environment, property loss, and psychological impact. One of disaster with the most frequent occurrence is a landslide. National Agency for Disaster Management (BNPB) noted since the beginning of 2017 to December 4th, 2017 recorded 577 incidents of landslides throughout Indonesia. A landslide is the movement of rock, earth, or debris down a sloped section of land (National Geographic, 2014). Major factors that caused a landslide are nature condition and human activity. Nature condition such as Geology refers to material characteristics itself. The trigger factors that make landslide happen are rain, land cover, slope, etc. Indonesia is starting the rain season, which means the risk of the landslide is increasing. Landslides have negative effects, damage to infrastructures such as road, buildings, communication system, and the deaths of people
