Abstract

Title : Study of Mass Movement And Critical Landslide On Purworejo District. The objective of the research is to study of mass movement and critical landslide area and also agricultural area degradation in Purworejo. Research method use in the cheking the real condition and also deviation occuring in the field. The research result was the critical area of mass movement and landslide concentrated hilly and mountainous area spreading the nortern and eastern area at 9 Sub District Bruno, Kaligesing, Bagelen and some part of Bener, loano, Pituruh, kemiri and somepart of Purworejo City Sub District. The cause of the mass movement and critical landslide area is the very steep topography used for mixed agriculture area and high intensity rain.

Abstract

Tittle : Study of Hidrology on Landuse Units Topography Karst Karangbolong. The objective of the research is to study of hidrology on landuse units topography karst Karangbolong. The methods of the research was descriptive analysis and  field survey on land units from maps overlays i.e geohidrology map, soilmap, geology map and landuse of Karangbolong map. The result of the research is that Karangbolong western hilly area and its surrounding  which an area 234 km2.  The  research area  has a high potential of water resources, due to several reason  the water cannot be used by people for agriculture purposes. The landuse forest is mainly belonging to Perhutani. On the stony area Tmk and Tmph or on U1,U2,U3 landuse units area or P1,P2,P3,  landuse located on the middle and northern does not change  too much and hydrological function is relative unchanged, but the southern area the landuse change too much. Therefore several activities experiences disturbance such as drying water resources and the formation of stalactite and stalagmite, and also several change of landuse such as paddy field becoming arid land, forest becoming settlement area and arid land.
