| Summary: | Movement soil and rocks including natural disasters that are often in parts of
Indonesia. Research on the vulnerability of soil and rock movement is needed in the
area of Hargorejo village, Kokap district, regency of Kulon Progo considering that
area is an area that is vulnerable to movement of soil and rock. The purpose of this
study was to: 1) Know the types of soil and rock movement of the study area, 2)
Knowing the dominant controlling factor which can cause soil and rock movements
occur in the study area, 3) Create a map of vulnerability movement of soil and rocks
in the study area. The method use in this study includes geological mapping, then the
specified parameters that are controlling for vulnerability of movement soil and rocks
are: slope, lithology, geological structure, surface soil types, and land use. From
parameters, made maps based on these parameters for later in the overlay using
Geographic Information Systems (GIS) produces map of vulnerability soil and rocks
movement . The conclusion of this study find that: 1) The movement of soil and rocks
are dominant in the study area in the form of creep and slide, 2) The most influential
parameter until not too powerful are lithology, geological structure, slope, surface
soil types, and land use, 3) There are 3 zones vulnerable of movement soil and rocks.
Vulnerability of high level zones are Hargorejo village, Tangkisan Dua, and
Ngaseman. Vulnerability of medium level zones are Kulur village and Tangkisan Satu.
Vulnerability of low-level zones is Temon Kulon village. |
