The Analysis of Slope Safety Factors at Post Mining Areas in Semaya Village, Randudongkal Sub-district, Pemalang

Abstract

Mining activities has become increasingly widespread in recent years, especially people’s mining, that
just concerned about the result and not paying attention to the environmental factors.This is caused
the post mining area’s destruction and environmental degradation potential. For this reason, the slope
safety factor enhancement analysis on the post mining area in Semaya Village, Randudongkal Sub-
District, Pemalang Regency is needed. Slope stability analysis using Slide 6.0 software to identify the
condition of post mining area from the results of undisturbed sample (UDS) laboratory data.
Laboratory testing includes several aspects including water content, weight, specific gravity, grain size,
atteberg limit test, and direct shear test. The value of the safety factor is 1,441, the value is in the safe
category because it passes the minimum value limit of the safety factor which is 1.25, this result is
obtained from the terracing modeling.
