Mine slope displacement at PT. Adaro Indonesia needs to be monitored continuously. The mine slope monitoring can be performed with various methods. One of the method is calculation with GeoMos software. However, due to the limited using of GeoMoS license in PT. Adaro Indonesia, they need to apply an alternatif method. In the research, the least square method is investigated to determine the slope displacement. This research used thirteen measurement data of monitoring points on five epoch observations. Computation was performed using parameter method of least squares adjusment. Global test was carried out to evaluate any gross error in the measurement. Analysis was done by comparing the computed value of displacement using least square adjusment and GeoMoS software. The value of the different displacement between the two computation statistically is not significantly different. The result can be used as consideration for PT. Adaro Indonesia to analyse the slope displacement. In addition, this study also generate dashboard visualization to display the monitoring data in Excel format that can be used in real-time to complement the software GeoMoS menu.
