<p align="justify">The XYZ tunnel is a civil tunnel dedicated to civilian tunnels, especially Railways. The XYZ tunnel is done using the NATM method (New Austrian Tunneling Method) where this method is a fairly effective method used in civil tunnels that penetrate the rock is quite weak. The NATM method consists of excavation of the tunnel itself, tunnel support to monitoring of the deformation itself. <br /> <br /> <br /> In this final project, NATM buffer analysis will be carried out using finite element method with Phase2 perangkat lunak, which in modeling with Phase2 will combine the secondary data obtained from the company in the form of intact rock characteristics of the tunnel itself, with actual data in the field in the form of data facemapping and tunnel monitoring data. From the results of this analysis, based on the strength factor, the deformation and yield element values around the tunnel, it is found that the tunnel is in stable condition at strength factor of 1.81. <p align="justify">
