Abstract

Malang Regency is one of the regency administration areas in East Java Province. The complex
physical condition of Malang Regency, especially its land reliefs accompanied by high rainfall, causes Malang
Regency obtain floods and landslides frequently. Based on the BPBD data in 2017, it is stated that around 80%
of Malang Regency is disaster-prone area of floods and landslides, especially in the southern part of Malang
Regency. This is caused by several natural factors, one of which is slope, and human factors called changes in
land cover. This study aims to examine the land cover factors that influence the extent of landslides that occur
in the Southern Malang Regency. The independent variable used is builtup area, dense tree vegetation,
vegetation of rare trees, shrubs, grass, open space, slope, and distance. Based on the results of multiple linear
regression analysis, it can be concluded that the builtup area cover with coefficient value 0.062 and open space
with coefficient value 0.020 are variables that are directly proportional to the area of the landslide that has a
higher percentage of the area of land cover being built and open, the area of landslides will increase, while the
variable cover of vegetated land has properties inversely proportional to the extent of landslides which means
that it can reduce the extent of landslides if the percentage of vegetated land cover increases.
