Abstract

The addition of the existing heap on the ground interface will affect the ability of subgrade to accept the burden of the embankment and other charges on it. The inability of subgrade in accepting the load will result in a decrease in the vertical deformation and collapse. The analysis was conducted on the National Roads Banda Aceh-Medan KM. 83 + 135 of the Seulawah. The purpose of this study is to analyze whether the brunt of the height of the pile (H Critical) have exceeded the carrying capacity of the subgrade. The analysis was performed by using Plaxis software. The implementation method used in the analysis based on the modeling of the pile height variations by reducing the height of the pile with a certain interval gradually until a critical height (H Critical) heap that causes the achievement of maximum decrease of 2.5 cm. The modeling result demonstrates that when the consolidation of the soil embankment on condition of Hheap soil = 6 m, Hheap soil= 5.4 m, Hheap soil = 4.8 m could able to reduce the height of the soil embankment by 10%, 20%, and 30%, and considered in an unsafe condition. While when the soil embankment consolidation reduce by 40% (H heap soil = 3.6 m) showing in a safe condition. This result shows that the forces acting on the pile-soil could not hold the load so that the interface is about to collapse.

Abstract

Road infrastructure is very important and is a key enabler for the economy. If the road infrastructure was damaged or had various problems such as sliding, the movement of goods and passengers will be hampered and delayed to the acceleration of development in the local area. The landslide and movement of groundwater is a problem that often occurs repeatedly on some streets. Therefore, it is necessary to study the strengthening of the slopes at the bottom of the road construction with retaining wall. This study aims to analyze slope stability by getting numbers Safety Factor (FK). The analysis is used to analyze the stability of slopesusing the finite element method with the help of software Plaids, The scope of this review includes the calculation of slope stability at the national road from Banda Aceh - Medan Sta. 83 + 185 Mount Selawah. The results of slope stability analysis on the existing condition by using Plaxis software at the point of a review is not safe (FK lower than 1.25). Thus, it is done handling the retaining wall, installation of anchors. Based on the analysis of slope stability after being given the strengthening of the slopes with a retaining wall and the installation of anchors using Plaxis software under the influence of traffic load in an unsafe condition (FK lower than 1.25). Then additional handling is done by changing the angle of the slope so that the value of the safety factor (FK) greater than 1.25.

Abstract

Clay soil from Desa Meunasah Rayeuk quarry in Kaway XVI,  West Aceh Regency is a land material frequently used for construction of road infrastructure. In this quarry, there are three types of soil based on the color, yellow, red, and gray. The three types of soil have expansive characteristics, so they are not suitable for subgrade.  This unoptimal characteristic can be improved through soil stabilization. One of them by utilizing the reaction of catinonization between lime Ca(OH)2 with the clay soil. Therefore, a research needs to be conducted to find out the characteristics of physical and mechanical properties of the original soil and the effect of cationization of the soil and lime mixture on the soil plasticity index and soil shear strength parameters. Testing is done through mineralogical test and ASTM standard tests that include physical properties, standard compaction, and direct shear strength test. Variations of lime addition are 0%, 3%, 6%, 9%, and 12% of the soil dry weight. The test results show that the addition of lime can reduce the soil plasticity index and increase the shear strength of the soil on some level. At mixing up to 12% lime, the soil plasticity index dropped to 12.93% in yellow clay, 11.12% in red clay, and 16,76% in gray clay. The plasticity index after the addition of 12% lime has not met the minimum plasticity index requirement, ie 11%. The maximum shear strength for yellow clay is obtained at 3% lime, and 6% lime for red and gray clays.

Abstract

The province of Aceh was struck by a massive earthquake and tsunami on Sunday, December 26, 2004. The earthquake and tsunami disaster killed 173,741 people and 116,368 people were missing. The earthquake and tsunami in Aceh Province resulted in thousands of houses and public buildings being damaged and caused almost half a million people to be refugees. This study aims to determine the level of preparedness for earthquake disasters on users of public buildings Office of the Governor of Aceh Government. This research uses survey method by distributing questionnaires to users of public buildings and observing the building of the Governor’s office of Aceh Government. The selection of samples in the field is using probability sampling method with purposive sampling technique which is the technique in determining the sample with certain considerations. Secondary data was obtained from literature review and previous research. Data processing uses analysis of validity and reliability and descriptive analysis with index frequency analysis. This study begins with the pre-survey process, where testing is conducted on the questionnaire to determine the level of validity and reliability in each item of statement tested so that the validity value is 0.312 greater than 0.3 and the reliability value is 0.613 greater than 0.6. The results of field observations have not yet fully indicated the components of public buildings that are ready to deal with earthquake. From the results of the frequency analysis the index obtained is as follows; aspect of knowledge and attitude has a score of 62% (good), aspect of policy and guidelines has a score of 66% (good), aspect of emergency response plans has a score of 65% (good), aspect of disaster warning systems has a score of 65% (good) and aspect of mobilization of resources has a score of 62% (good)

Abstract

As we know, there is still a lack of the optimal effort for temporary evacuation sites to face the various threats of the earthquake which may caused the tsunami in the city of Banda Aceh. To deal with this serious threat, it is necessary to prepare a place of salvation to face the tsunami. In this case, it is an escape hill. The objective of this research is to determine the bearing capacity of the subgrade to the escape hill planning and the amount of the settlement, due to the load of the embankment height (Hcrit) and the value of the slope safety factor (FK). This research is conducted in Desa Deah Baro with the GCS coordinates (Geographic Coordinate System) 5º33'45.72"N 95º17'51.34"E which was calculated by using the Plaxis 8.2 computing system on the variations of the embankment height which started from the existing which is 2,0 m height, 4,0 m, 6,0 m, 8,0 m, 10 m and 12 m (run-up performance). As the results of analysis, the researcher found that the addition of the load due to the increase in soil embankment height has resulted in an increase in the value of settlement to the soil stability with an average percentage of 2,86% and the safety factor decreasing value (FK) numbers on slopes with an average percentage of 0,10%. At 2,0 m embankment heights, the researcher obtained a settlement value of 0,271 cm with the safety factor value (FK) is 1,684 greater than 1. Furthermore, with the embankment height of 4,0 m, there is a settlement of 1,139 cm dan safety factor (FK) 1,365 greater than 1. At a embankment height of 6.0 m there is a settlement of 3,035 cm and a safety factor (FK) 1,214 greater than 1. At embankment heights of 8,0 m, the settlement is 6,244 cm with a safety factor (FK) 1,135 greater than 1. For embankment heights of 10 m and 12 m, the decrease occurred was 10,991 cm and 17,446 cm with safety factor (FK) = 1,095 and 1,044~1. The occured decline was still within the tolerance limits, so that the subgrade was still able to withstand the embankment. The results of the value of the safety factor (FK) showed that the slope was safe and did not indicate the slope slides.
