ABSTRACT

This study aims to determine the causes of landslide disaster and to find out how to cope with triggered landslide around along the axis of Balikpapan Samarinda road in SoehartoHill Forest Park. Based on the analysis at the location of the research of land texture in Soeharto Hill Forest Park area is yellow Podzolic soil type, Latosol and Litosol (15%) and Alluvial soil (10%) with parent material in the form of folds of hill and. The structure of the soil is clumped and its consistency is flat.The topographic state of the field is bottom to bumpy to the slope of 10-45%.Referring to the general nature of soil chemical physics, most soil types in the Bukit Soeharto Forest Park area have a high degree of erosion sensitivity with very low land productivity, so it is appropriate to be designated as a conservation area. One of the geological processes that become the main cause of soil movement is rock weathering, rock characteristics in the research location of weathering occurs because of the weather is in tropical climate with high intensity.The location of the study is a hilly area that forms a slope of land with an average slope of 25 to 75 degrees and is composed by a pile of soil formed by physical and chemical weathering on rocks or more compact soil has the potential to move or landslides. The cause of a landslide disaster along the Balikpapan-Samarinda axle road in Soeharto Hill Forest Park is due to high rainfall and deforested land cover deforestation.
