Abstract

This is the result of applied remote sensing  for geological study the mass wasting in Karangkobar, the district of Banjarnegara, Central Java. The study on the mass wasting use the remote sensing method, by interpreting the blackwhite panhromatic aerial photographs, on the scale 1 : 50,000. The study is aimed at 1) revealing the capacity of the aerial photograph in supporting the study the mass wasting that an be identified by the aerial photographs; 2) to find out the influence of the physical environment and land-use on the mass wasting processes. The study in performed by using the visual interpretation method of the scale 1 : 50,000 black-white panchromati aerial photograph taken in 1994, using mirror stereoscope. The outcome of the aerial photograph interpretation is varis the quality of data and information. The data of interpretation of aerial photograph and the varis outcome in the spot are further tested in terms of its accuracy, particularly in its reltion with the aerial photograph interpretation. The technique of data analysis of the physical environment and the mass wasting is descriptive – comparative. The result of the study shows that the 1 : 50,000 black-white panchromatic aerial photograph can be used to identify and study both the mass wasting and influence of the physical environment on the mass wasting processes. The degree of identifying the mass wasting based on the aerial photograph interpretation is 75%. Compared to the previous studies, the present study hows that the mass wasting can be identified more easily by means of the 1 : 50,000 black – white panchromatic aerial photograph. Identifying the distribution of mass wasting are: a) the geological element (rock, geological structure, and stratigraphy); b) geomorphological elements (landform and the forming processes); the water condition (surface water and groundwater); and landuse (type and distribution). White marl – claystone type is the physical environmentsal element that has the most type is the physical environmentsal element that has the most dominant influence on the occuring of mass wasting in Karangkobar area.

Abstract

The purposes of the study are (1) studying the characteristics of the landslide hazard level, vulnerability, and capacity dealing with the seasonal plant farmland, and (2) developing the conceptual model disaster risk of landslide for the seasonal plant farmland at the stato volcano area. Sampling of the land factor was carried out in a purposive way and the sampling of the people was carried out accidentally. The analysis was conducted descriptively, parametric and non-parametric statistics, and spatial analysis of ecological map, land shape, slope, soil and land use. The findings showed that the extremely high landslide risk occurred at the cone shape of the incised volcano and the slope of the incised volcano. The economic vulnerability of one-seasonal crop farmland was about Rp. 8,879,310 ha/year-Rp. 44,036,061 ha/year. While, the socio-economic factor of the farmers was generally characterized by a transition into a periurban area. The conceptual model tated that the resources of seasonal plant farmland with the high risk of landslide can be cultivated with the acceptable risk if the vulnerability of agricultural commodity is low in economic value and the capacity of farmers cultivating it is high.
