Abstract
Landslide disaster is one of the most occur disasters in Suwidak, Banjarnegara.
Landslide is a recurring event and until now there is no suitable method to respond to the
t, so the preventive stage have not been maximized. According to the rese
vement of land in the area is very active but can not be known qua
quantitatively the level of activity that can cause landslides. The long-term goal of this
research is to make the landslide prone areas map.
There are two methods that used to achieve these purposes. The method that used to
identificate landslide zoning in research area is geology and landscape morphology mapping.
Meanwhile the second method to calculate the movement of the land using ground
positioning observed over a period of time, analyzing the movement using parameter
significance difference test, congruency test and point movement test.
Based on the geology and landscape morphology mapping, the slope in Suwidak are
30 - 70%, while the rock type are interbedded shale and calcareous sandstones from
Rambatan Formation. Geological structure that found is right slip fault (Rickard, 1972), with
strike and dip of fault is N 3100E/780, Angle of direct shear is 10o with safety factor value is
0.868 included into the unstable class. Those factors related with the result of movement that
measured with GPS geodetic. Based on the result indicate that the measurement point was
move from first periode to third periode measurement.
