Abstract

A slope assessment to predict the probability of landslide occurrence and the safety factor of landslide at E9 building, Home Economics Department, Universitas Negeri Semarang was conducted to obtain a safety factor index of slope and structures in study area. A rupture of soil surface appeared in some parts of the study area. It indicated an initial destruction of structure and infrastructure. Differential settlements occurred in north side of building. Therefore, a downward movement of soil, rock mass and debris to the slope direction was identified as an initial hypotheses. The influence of season was analyzed in this paper. A combination of LHZ method and numerical analysis by Plaxis version 9.2 was utilized for the predicted behavior of soil movement and the safety factor. The results of analysis revealed that the safety factor in the wet season reached 1.0635 and in the dry season reached 1.075. From this results, it can be concluded that the influence of season parameter of the season did not affect for the possibility of landslide in this area.
