Abstract

The collapse of the banks of the Dondang river at the BLC2 project site of PT. Kutai
Energi caused the barge to not dock and the conveyor to be unusable. One of the
causes of landslides is changes in river water levels which cause the soil around the
river banks to become saturated and unstable. The research begins with a survey
and data collection related to the research location. Analysis using GeoStudio
(Slope/W) 2012 software was carried out with two models, namely when the river
water level is normal and when the river water level is in a flooded condition. The
results of the analysis show that the critical condition occurs in the second condition
where the river water level is in a flood condition. In these conditions, it is known
that in the existing condition of the slope without reinforcement, the value of safety
number (SF) = 1.125 is obtained. On the other hand, when the pile reinforcement is
given, the slope safety score increases to 1.741 which indicates that the plaster can
overcome the sliding on the cliff due to the influence of the river water level
