| Abstrak/Abstract |
Blukar, Bodri and Blorong watershed is located in a part of Kendal, Semarang,
Temanggung, and Wonosobo Regency. The study area has some problems of
landslides and misuse of land. The research was proposed to determine the regions
having priority of landuse assessment based on the land capability, landslide hazard
and population pressure analysis. The aim of this research was to find better criteria
for land capability based landslide hazard for land use priority in Blukar, Bodri, and
Blorong watersheds. This research was carried out using field survey. The field
survey was based on stratified random sampling of landform unit as area sampling
unit. The LCLP software was applied for land capability classification. The
Soemarwoto’s method was applied for the evaluation of population pressure on the
agriculture land. Landslides classification is to determine landslides hazard by
classification and rating on each factor that influences to landslide and multiplied by
weight on that each factor. The results shows: (1) land capability in the study area
was varies from class II – class VII with limitation factors of slope, soil erodibility, soil
texture, soil permeability, drainage and soil efectif depth, (2) the most of the study
area (64.68%) has TP<1, it means in arable land does not have population pressure of
agriculture land, (3) The result of landslide hazard showed that Class I and V is low
and Low, Class III and IV is medium and high, and Class VI and VII is high, (4) Land use
priority of class I is for very intensive agriculture, class II is for intensive agriculture,
class III is for extensive agriculture, class IV is for marginal agriculture, class V is for
grassing and aqua-agriculture, class VI is for limited grazing/plantation, and class VII
is for production forest, (5) From this research, it can be known that high landslide
hazard happened in class VI until class VII. Actually in the field, it indicates that land
use in class VI until class VII is unsuitable with their land capability |
