Abstract

This paper contains an analysis of the loading and the position of rock in the bridge foundation based on the rock's response to the force that will be tested with "Graphic User Interface (GUI)" program using MATLAB. This paper also explains the preparation of bridge foundation modeling based on the forces tested on the rock named ‘x’. The response forces discussed in this paper are normal force, latitude force and moment force.                 The data is processed using MATLAB software and then presented in the form of tables, graphs and 2D modeling that shows the loading and the position of rocks correspondence to the bridge foundation. After obtaining the rock’s ‘x’ data, the data is then processed using Graphic User Interface program, through the program moment force graphs, normal force graphs, latitude graphs can be obtained which later these results can be considered for modeling the loading and the position of the rock’s ‘x’.                 Through the data processing that has been done, zero normal force is obtained, and the latitude has a value of about (0 to 8) N and the moment force of about (-60 to 0) N. Based on these calculations it was found that the rock’s 'x' can be modeled by arranging it rectangle with center of gravity evenly distributed at the center. And the model that are used is the placement pinch model because it does not have translational and rotational values so that the rock ‘x’ is suitable to be the bridge's foundation.Keywords: Shear forces, Bending Moment, Normal Forces, GUI, Modelling

Abstract

Geographically, although Indonesia has the potential for tremendous natural resources, it is also prone to natural disasters, particularly landslides. It is due to the large number of highlands and mountains, including Madiun Regency which has Mount Wilis. Madiun Regency is an area affected by landslides. Therefore, this paper aimed to investigate landslide hazard areas (KRB) in Madiun Regency using a Geographic Information System (GIS) with secondary data sourced from SRTM USGS, BMKG data, Google Earth, and BPS data for Madiun Regency which was processed using ArcGis 10.7 software with the Union Overlay Analysis method based on weighting on the landslide disaster parameter map. The processed data produced a map of population density, geology, rainfall, slope, and a map of the Landslide KRB in Madiun Regency. The Landslide KRB Map shows that Madiun Regency has a relatively low (safe) hazard to landslides. The areas with the potential to experience landslides are in the west, including Pilangkenceng, Balerejo, Jiwan Districts, and parts of Kebonsari and Dolopo Districts with an area of 192.07 km2 for high hazard and 1.39 km2 for very high hazard. It is because these districts have extreme rainfall with an intensity of above 150 mm and a relatively dense to very dense population density. The Landslide KRB Map of Madiun Regency can be a reference source for residents and the public to determine the hazard points of landslides in Madiun Regency so that they can prepare for landslide disaster mitigation to minimize the impacts and losses that occur
