Abstract

The bearing capacity of soil provides the most important output for soil investigation. Bearing capacity becomes a reference in designing the substructure of the structure. Therefore, it is necessary to have a capable bearing capacity analyzed by varying the shape of the foundation to provide a clear description of the highest bearing capacity of all the variations presented. In this study, a soil investigation was carried out by using the Cone Penetration Test from several distribution locations in Gunung Anyar District Area, where it is well known as cohesive soil which has a lower bearing capacity compared to non-cohesive soil. Based on this analysis, it shows that the pile foundation using a square cross-section will provide a greater value for the pile bearing capacity. Increasing the dimensions of the cross-sectional shape, it will provide a greater value for the carrying capacity of the pile as well. This is evidenced at a depth of 16.4 m, for a square cross-sectional dimension of 0.4 m it gives a value of 80.49 tons, while for a cross-sectional dimension of 0.6 m it gives a value of 164.736 tons.

Abstract

Railways in Indonesia still show problems, such as time delays. To make train services in Indonesia better, government efforts are needed, one of which is the development of new infrastructure, such as the construction of a double-track train such as Sepanjang to Mojokerto segment. So it is necessary to analyze the level of service both in existing conditions and after construction. The analysis was carried out in two conditions, namely, full single track and full double track. For full double-track reference, a simulation is carried out with an auxiliary program, namely the Railway Operation Simulator (ROS). By entering data in the form of station layouts, train facilities, and signaling systems and blocks. Based on the analysis results, it shows that the double track in the Sepanjang-Mojokerto segment affects the level of service. The prediction of service levels for the Sepanjang-Mojokerto segment shows that three road plots have LoS A. So, overall, with the construction of the double track, this segment is operating below capacity and has low traffic.
