Abstract

In civil engineering, soil plays a crucial role as it supports the strength of the construction above it.. Thus, research was conducted on native soil in the Tais-Maras region of South Bengkulu Regency. Testing was carried out to determine the properties of the native soil intended for construction activities, including water content according to SNI 03-1965:2008, specific gravity according to SNI 03-1964:2008, plastic limit according to SNI 03-1966:2008, liquid limit according to SNI 03-1967:2008, hydrometer analysis according                                     to SNI 03-3423:2008, activity value, CBR according to SNI 03-1744-1989, and shrinkage limit research according to SNI 03-1996-1990. Based on research and data calculation from disturbed soil samples in the Tais-Maras region of South Bengkulu Regency, the soil properties were determined as follows: water content (W) 98.52%, specific gravity (Gs) 2.415, liquid limit (LL) 45%, plastic limit (PL) 33.85%, Plasticity Index (PI) 11.2%, Optimum Moisture Content (OMC) 34.9%, dry density 1.120 Kg/Cm3, and a CBR design value of 3.9%. The calculated shrinkage limit value was 38%, and the soil activity value was 2.6. It can be concluded that this soil belongs to the OL category, with 'O' representing organic silt due to the hydrometer analysis showing particle sizes ranging from 0.002 mm to 0.0074 mm with high plasticity and moisture content, thus indicating that it is unsuitable for bearing construction loads.

Abstract

Foundation is a structural element that functions as a support for the construction loads above it. These loads are transmitted to the soil, so the depth of the foundation must reach the depth of hard soil; therefore, the determination of the depth and type of foundation used must be based on soil investigation conducted during the bridge construction planning phase. The Kikuba bridge project is planned to use pile foundations with a depth of 5 meters. After conducting soil investigation using drilling equipment, the N-SPT 60 results for Abutment-1 were obtained at an average depth of 19 meters, rendering pile foundations unsuitable. The accuracy of selecting the type of foundation used depends greatly on the depth of hard soil. The Kikuba bridge construction project encountered an average depth of hard soil at 19 meters, thus necessitating an analysis to change the design from pile foundations to bore pile foundations, while meeting the technical requirements of the foundation and analyzing using the Meyerhoof method.

Abstract

Road surface smoothness measurements are not widely conducted in Indonesia due to limited equipment, resulting in inadequate monitoring and evaluation of existing road constructions according to national road sector standards. Road surface smoothness levels can be determined by measurements using various methods recommended by Bina Marga and AASHTO. One method recommended by Bina Marga for measuring road smoothness levels is through road damage survey forms according to the 2015 road condition reporting guidelines. The average road damage level for the Sp.Kerkap–Batas Sumber Road Section is 5.130%. The location Km.Bdg. 63+000-64+000 has the highest IRI value of 12, dominated by damage such as shallow potholes covering an area of ​​8,916.56m², which is planned to be repaired using hotmix patching. Therefore, road observers must be vigilant and regularly report road damages every month to ensure the stability and condition of the road are well maintained, in order to facilitate and support economic flow/velocity. Proper and appropriate handling will keep the road in good condition based on the planned road stability.

Abstract

Composite column structures can provide high strength from the combination of two or more materials with different material properties which then provide better combined properties. This research was conducted by analysing the composite column structure with finite difference method and comparing the results with CSiCol application. The results of the analysis of   the Pn and Mn interaction diagram of the finite difference method composite column when compared to the CSiCol application composite column have a maximum percentage difference for the maximum Pn value of 19.17%, the maximum Mn value of 2.90%. The difference in the Pn and Mn values of  the composite column can be corrected with a regression equation using a linear correction factor and a Polinomial correction factor, with a maximum Pn percentage difference value of 8.93% for the linear correction factor and 6.84% for the Polinomial correction factor value. Therefore, the finite difference method can be used to analyse composite columns with relatively good accuracy provided that correction factors are used.
