Abstract

In the construction process, a building requires good planning, because structural elements must be able to receive loads in the form of axial directional loads such as gravitational loads as well as lateral directional loads such as wind loads and earthquake loads, all of which will later be passed on to the lower structure, namely the foundation. One of the things that is reviewed from the foundation is the value of the carrying capacity, to find out the value of the carrying capacity of a foundation can be calculated theoretically based on data from soil investigations in the field. Meanwhile, the Pile Driving Analyzer (PDA) is used to verify the results of the calculation. This study aims to calculate and analyze the bearing capacity of the foundation compared to the results of PDA. The method used is the Schmertmann & Nottingham method as well as the Mayerhoff method. The results of this study are carrying capacity using the Schmertmann & Nottingham method based on the results of the sondir test at the S1 point obtained a result of 804.15 tons, at the S2 sondir point the result was 761.99 tons, the S3 sondir point was 823.45 tons and at the S4 sondir point of 841.68 tons. The carrying capacity using the Meyerhoff method based on the results of the sondir test at the S1 point obtained a result of 572.39 tons, the S2 sondir point was 568.93 tons, the S3 sondir point was 568.84, and the S4 sondir point was 562.4 tons. The largest ultimate bearing capacity (Qu) value is obtained from the Schmertmann & Nottingham method at the sondir point S4, The smallest ultimate bearing capacity (Qu) value is obtained from the Meyerhoff method at the sondir point S4. The calculation results that show the least difference and are closest to the PDA are using the Meyerhoff method at the S4 sondir point and the BP-109 PDA with a difference of 115.5 tons. The Schmertmann & Nottingham method shows much greater results than PDA calculations

Abstract

Quality control in the Package 6 Patimban Port reclamation project greatly determines the stability of port operations. This study aims to analyze the correlation between the average soil density (Sand Cone) of layers 1–7 to the surface bearing capacity (Field CBR) of the subgrade and formulate a prediction model. Using a quantitative approach, this study analyzed 26 samples using simple linear regression without a constant (regression through the origin). The results of the analysis showed a very strong and positive correlation relationship with the value of R = 0.976. The resulting prediction model is Y = 0.141X with a coefficient of determination (R2) of 0.953. This proves that 95.3% of the variation in Field CBR values is significantly influenced by the average density of all layers of the landfill. These findings confirm that every 1% increase in average density increases the Field CBR by 0.141%.

Abstract

Mini Hydro Power Plants (MHPs) utilize the potential of water to generate electrical energy. However, construction on clay soils that have the potential to expand and contract can affect the stability of the structure. This study aims to evaluate the potential for soil development in the Cileunca MHP. The methods used to determine soil development potential include Chen (1988), Skempton (1953), and Seeds (1962) methods. Mineral identification was conducted through X-Ray Diffraction (XRD) testing of soil samples taken by the handboring method. The results of the analysis showed that the Skempton method showed 67% of the samples had activity values > 0.75 (“high” category). The Chen method indicated 60% of the samples had a plasticity index (PI) > 35% (“very high” category). The Seeds method indicated 73% of the samples had a development potential > 25% (very high category). XRD testing indicated the dominant mineral was dehydrated Halloysite (Al2Si5(OH)4). The soil at the Cileunca MHP site has a high development potential that can damage building foundations. Foundation stability is strongly influenced by expansive soil properties, so soil stabilization treatment is needed to prevent structural damage. This study concludes that the soil at the Cileunca MHP site has a high development potential, which can cause structural problems. Therefore, soil stabilization treatment is highly recommended to ensure the stability of the building foundation
