In the Kediri Regency area, it is planned to build a 3-story shophouse as one of the supporting facilities and the community’s economic needs. This area has sandy soil conditions and a high-water table. The purpose of this study was to calculate the carrying capacity of the soil in constructing a 3-story shophouse using the Terzaghi, Mayerhof, and Hansen methods. The condition of the soil with a relatively high groundwater table made the implementation of the footplate foundation less effective, so a modification of the foundation was made, which added three mini-piles measuring 0.4x0.4x1.5m, with a design load supported by the foundation of 100 t/m². Calculations with the Mayerhof and Hansen methods have nearly identical results but have not fulfilled the planned load. At a foundation depth of up to 3 m with an SF value of 3, for the Terzaghi method: 107.75 t/m2, the Mayerhof method: 92.51 t/m2, and the Hansen method: 94.68 t/m2. The results can be used as an alternative in constructing a 3-story shophouse with sandy soil conditions and high groundwater levels. This research can also be a reference for other regions facing similar problems.

This study aims to enhance the bearing capacity of pile foundations in sandy soils through a bio-inspired approach by modifying Meyerhof’s empirical equation using a cranial correction factor. The adjustment considers the geometric influence of the asperity length–height ratio (L/H 20, 26.67, and 33.33) applied to different pile diameters. The analysis was carried out theoretically by calculating point resistance (Qp) using the modified equation, followed by validation through ANOVA and the nonparametric Mann–Whitney test. The results indicate that an L/H ratio of 20 provides the most significant improvement in Qp, ranging from 11.7% to 465.8% compared to the conventional Meyerhof model, particularly at lower D/B ratios where stress concentration can be optimally mobilized. Larger ratios such as 26.67 and 33.33 also improve capacity, though less effectively than L/H 20, yet still outperform unmodified foundations. The correction factors obtained, ranging from Cᵣ 1.07 to 5.66, demonstrate the substantial contribution of geometric modification to load transfer efficiency. The novelty of this research lies in integrating anisotropic interface properties into the classical Meyerhof model, thereby bridging the gap between isotropic predictions and anisotropic experimental evidence. Accordingly, the developed theoretical framework not only strengthens the basis for calculating pile bearing capacity but also opens new avenues for bio-inspired foundation design that is more efficient and sustainable.

Sandy soils are commonly employed as the foundation for shallow footings. However, their relatively low bearing capacity often leads to excessive settlement and deformation. This study examines the potential application of the Enzyme-Induced Carbonate Precipitation (EICP) technique based on soybeans. Utilizing urease derived from soybeans to catalyze the crystallization of calcium carbonate (CaCO₃). This research investigates the impact of EICP-induced carbonate precipitation on the bearing capacity of sandy soil in square footings. 4 x 4 cm footing model was tested using the AIC-Innovation Loading Test apparatus. Direct shear additional tests were performed to assess differences in increase cohesion and shear angle. The results show 174.90% increase in bearing capacity, 73.47% reduction in settlement, 300.64% increase in cohesion from the shear test, and 202.46% increase from the loading test. The shear angle increased by 56.34%, and the dry unit weight increased by 36.5%. ANOVA analysis with a p-value of 2.03 × 10⁻¹⁵ < 0.05 confirmed that the increase in bearing capacity was not due to random variation but to the EICP treatment. These findings demonstrate that EICP proves to be a viable technique to enhance sandy soil and contributes to advancing of bio-cementation based on organic materials as a sustainable solution.

Low-plasticity clay (CL) soils are commonly found in tropical regions and generally have high water content, which reduces shear strength and lowers the slope safety factor (Fs). Conventional stabilization methods such as cement and fly ash are considered environmentally unfriendly because they produce high carbon emissions. Microbially Induced Calcite Precipitation (MICP) has emerged as a sustainable alternative for enhancing soil strength through the formation of biologically induced calcite. However, most previous MICP studies on slopes have focused on sandy soils, erosion control, and bioaugmentation. Therefore, it is necessary to investigate the application of Biostimulated MICP on high-moisture CL soils that represent tropical conditions and their relationship with slope Fs. This study aims to evaluate the effectiveness of biostimulated MICP on the stability of high-moisture CL soil slopes. Small-scale slopes were created in boxes with a 60° angle using the air pluviation method. The biostimulation solution used included urea, CaCl?, CH?COONa, NaOH, and sugarcane molasses to activate indigenous urease-producing bacteria. Testing included direct shear tests and slope-model loading tests with incubation times of 0 and 7 days. Fs analysis used an infinite-slope approach under steady-state seepage conditions. The results showed a 90.15% increase in cohesion and a 37.05% increase in internal friction angle, thereby increasing Fs to 88.72% after 7 days of MICP treatment. The results of the slope loading test showed a 105.41% increase in slope bearing capacity. These results indicate that the increase in cohesion and friction angle due to MICP is reflected in the slope's load-carrying capacity and in an increase in the Fs value. The findings indicate that biostimulated MICP has the potential as a sustainable slope stabilization technique and is suitable for tropical soil conditions.

Differences in pile dimensions and layered soil geotechnical characteristics have the potential to reduce the accuracy of foundation bearing capacity estimation; therefore, a more accurate and verified calculation approach is required. This study evaluates the ultimate bearing capacity (Qu) based on Cone Penetration Test (CPT) data by comparing the Meyerhof method and the Schmertmann–Nottingham method for piles with diameters of 20 cm, 40 cm, and 60 cm at two test locations (S1 and S2). The evaluation results indicate that the Schmertmann–Nottingham method produces higher Qu values than the Meyerhof method for all pile diameter variations, with a very strong linear relationship between pile diameter and Qu, as indicated by the coefficient of determination (R2 >= 0.97). Statistical validation using ANOVA proves that both the calculation method and pile diameter have a significant effect on Qu, with pile diameter being the dominant factor in increasing the sensitivity and reliability of ultimate bearing capacity estimation based on CPT data.

Abstract Due the construction phase in project of the Dhoho Kediri International Airport Toll Road at STA 7+000 â€“ STA 7+100 mentioned soft soil, leading to significant and time-consuming consolidation. In an effort to expedite the consolidation process, the preloading method with Prefabricated Vertical Drain (PVD) is applied. This method includes backfilling plan and PVD installation to reduce the flow of pore water in the soil, allowing for faster consolidation. This research aims to enhance the effectiveness of soil improvement by evaluating the influence of PVD installation distances in a square pattern. The research focuses on the analysis of soil parameters and PVD installation at distances ranging from 1.1m to 1.7m. The results indicate that the installation of square-patterned PVD is effective in accelerating consolidation. The final settlement prediction using the Terzaghi One-Dimensional approach provides practical references. Simulation results for distances between 1.1m and 1.7m show that 1.1m is the most effective distance because closer PVD installations result in faster consolidation times. This is evidenced by the consolidation time comparison, where without PVD, it takes 51,92 years to achieve 90% consolidation, while with PVD, it only requires 144 days. These findings are expected to provide practical guidance and significant contributions to the design of soil improvement in similar toll road construction projects.

Tanah lempung adalah salah satu jenis tanah lunak berbutir halus dan memiliki luas permukaan yang lebih besar dibanding diameter partikelnya. Tanah lempung memiliki kompresibilitas dan pemampatan yang tinggi, serta memiliki sifat kembang susut akibat interaksi dengan air. Faktor tersebut mengakibatkan daya dukung tanah menjadi rendah sehingga rawan terjadi kelongsoran apabila tanah tersebut dijadikan sebagai dasar perletakan konstruksi. Oleh karena itu perlu dilakukan stabilisasi tanah. Tujuan stabilisasi tanah adalah untuk meningkatkan kemampuan tanah dalam menahan beban dan daya dukung dengan peningkatan parameter kuat geser tanah. Berdasarkan hasil penelitian uji kuat geser langsung yang dilaksanakan di Laboratorium Teknik Sipil Universitas Kadiri menggunakan mesin Direct Shear Test diperoleh nilai kohesi sebesar 0,224 kPa dan nilai sudut geser dalam sebesar 3,783°, sehingga dapat disimpulkan bahwa tanah di wilayah Universitas Kadiri ini rawan terjadi kelongsoran dan perlu dilakukan upaya stabilisasi tanah apabila difungsikan sebagai dasar perletakan suatu konstruksi.

Tanah pasir lepas memiliki daya dukung rendah akibat porositas tinggi dan ikatan antarbutir yang lemah. Kondisi ini menjadi tantangan signifikan dalam perencanaan konstruksi fondasi dangkal, karena berisiko menyebabkan penurunan berlebih dan ketidakstabilan struktur. Penelitian ini bertujuan mengevaluasi efektivitas metode Enzyme-Induced Carbonate Precipitation (EICP) berbasis ekstrak kedelai dalam meningkatkan kapasitas daya dukung tanah tersebut. Perlakuan dilakukan satu kali dengan menyuntikkan 9 liter larutan EICP ke dalam media pasir menggunakan metode two-phase. Rasio larutan urease (dari ekstraksi bubuk kedelai) dan sementasi (1 mol/L urea dan 1 mol/L CaCl₂) adalah 1:1, dengan konsentrasi total 22,24% terhadap berat kering pasir. Pengujian meliputi uji beban statik aksial (ASTM D1194) dan uji geser langsung (ASTM D3080). Hasil menunjukkan bahwa kapasitas daya dukung ultimit meningkat sebesar 272,7% (uji aksial) dan 368,2% (perhitungan). Peningkatan sifat tanah juga terlihat dari nilai kohesi hingga 13,78 kPa, sudut geser dalam mencapai 57,16°, dan berat volume tanah naik dari 13,48 menjadi 18,00 kN/m³. Uji ANOVA (F(1,114) = 239,97; p < 0,001) mengonfirmasi pengaruh perlakuan yang signifikan secara statistik. Disimpulkan bahwa metode EICP berbasis kedelai efektif dalam memperbaiki sifat fisik dan mekanik tanah pasir lepas, serta meningkatkan daya dukung fondasi telapak lingkaran secara signifikan.
