Abstract

Seepage is an inevitable occurrence in embankment dams, but under certain conditions, it can lead to piping. Piping is the formation of cavities in the soil due to the transport of fine soil particles by seepage forces. This phenomenon is one of the serious issues that can affect the stability of the dam. This study aims to analyze the potential for piping in one of the dams located in West Java using finite element and empirical equation methods. The finite element method analysis was conducted to obtain the exit hydraulic gradient values in the dam to calculate the safety factor against piping hazards. Meanwhile, the empirical equation used the weight creep ratio (WCR) to assess the potential for piping. The potential for piping analysis was conducted under minimum, normal, and flood water level conditions. The results of the finite element analysis showed that the hydraulic gradient exit values ranged from 0.20 to 0.33, resulting in safety factors ranging from 4.58 to 8.25. The obtained safety factors still meet the minimum safety factor criteria required by SNI 8065:2016, which is 4. The potential for piping analysis using the empirical approach yielded WCR values under the minimum, normal, and flood water level conditions, which were 4.71, 3.36, and 3.30, respectively. The calculated WCR values are higher than the typical value for WCR in hard rock, which is 1.6. Based on these two analyses, it can be concluded that the dam is safe against piping hazards.

Abstract

The characteristics of soil, which are homogeneous or even very different even at short distances, are one of the reasons why it is important to carry out geotechnical investigations for building foundation design to prevent failure or excessive settlement. This research aims to determine the geotechnical characteristics of the container port location plan in Raha City. Deep boring and SPT tests were carried out at 2 points: BH-01 in the wharf area and BH-02 at the access road area to the dock (trestle and causeway). Apart from that, samples were taken from two drilling holes to be tested in the laboratory. Laboratory test results obtained based on the USC classification of all samples were classified as silty sand soil (SM) with low plasticity. The boring results show that the hard soil layers in BH-01 and BH-02 are, respectively, at a depth of 12.5 m and 16.5 m. The allowable bearing capacity (Qa) of round piles with a diameter of 45 cm at a depth of 9 m, 10 m, and 11 m with a safety factor of 4 is respectively 892 kN, 919 kN, and 946 kN for BH-01 and 913 kN, 940 kN, and 968 kN for BH-02. The allowable bearing capacity (Qa) of round piles with a diameter of 50 cm at a depth of 9 m, 10 m, and 11 m with a safety factor of 4 is respectively 1057 kN, 1084 kN, and 1112 kN for BH-01 and 1079 kN, 1106 kN, and 1133 kN for BH-02.

Abstract

Slope stability represents a major challenge in infrastructure development, particularly in regions with complex geotechnical conditions. This study aims to evaluate the effectiveness of slope stabilization methods using a numerical simulation approach based on the Finite Element Method. The study was conducted on a road section in Southeast Sulawesi, characterized by silty sand soils prone to erosion. Soil investigation data were obtained through cone penetration tests (CPT) to determine soil parameters for the analysis. The slope reinforcement alternatives involve a combination of gravity-type retaining walls (DPT) with mini bore piles and the installation of gabions on riverbanks. The gabions are intended as a long-term mitigation measure to reduce erosion risks on the riverbanks. Simulation results indicate that integrating DPT with mini bore piles enhances slope stability, achieving a safety factor of 1.58 during flood conditions, meeting the minimum criterion of 1.5 according to SNI 8460:2017. Although scouring effects reduce the safety factor to 1.53, this value remains within acceptable limits. The greatest displacement occurs at the toe of the slope but is effectively minimized with the designed reinforcement. This study highlights the importance of the finite element approach in understanding soil-structure interactions. The findings provide practical recommendations for slope reinforcement, especially in areas with high geotechnical risks. Regular monitoring of riverbank erosion is advised to maintain slope stability sustainably.

Abstract

Soil conditions are a critical factor influencing the feasibility and success of construction projects, especially for infrastructure that interacts directly with the ground, such as foundations and slopes. Geotechnical issues like excessive settlement and shallow translational landslides often occur due to insufficient understanding of soil characteristics. Soils with high clay content or low density are prone to volume changes and water saturation, which can threaten structural stability. This study aims to examine soil characteristics at the research site by integrating field tests (Cone Penetration Test/CPT) and laboratory tests to evaluate soil bearing capacity and slope instability potential. The methods included CPT at seven points and laboratory tests on seven soil samples to analyze physical and mechanical properties, such as grain distribution, Atterberg limits, and shear strength parameters. CPT results showed a dominance of silty sand with very loose to loose density in the upper layer (0–2 meters) and medium to dense density in deeper layers (>6 meters). Laboratory tests identified variations in soil classification, including silty sand (SM), silt (ML), and high-plasticity clay (CH), with low cohesion (6–10 kPa) and internal friction angle (4.85°–8.38°). Data integration revealed a high landslide risk in the upper layer due to water saturation, necessitating mitigation strategies such as deep foundations and effective drainage systems. This research provides significant contributions to safe and sustainable construction planning in areas with similar soil conditions.

Abstract

Soil compaction is a critical phase in construction projects, particularly those requiring long-term structural stability. The compaction process aims to increase soil density, enabling the soil to support structural loads without excessive settlement. This study was conducted to evaluate the effectiveness of soil compaction used as fill material in an industrial development project in Southeast Sulawesi. A quantitative approach was employed by combining laboratory testing using the standard Proctor method and field evaluation using the sand cone method. Soil samples were directly taken from the project site and tested in the laboratory to determine the maximum dry density (γdmax) and the optimum moisture content (wopt). Laboratory results indicated a γdmax of 1.69 gr/cm³ and a wopt of 28.80%. Subsequently, sand cone tests were performed at eight field locations after the compaction process was completed. The results showed that the field degree of compaction ranged from 77.8% to 90.4%, which is below the minimum technical standard of 95%. This discrepancy is attributed to excessive moisture content and a lack of control in field execution. The study highlights the importance of synchronizing laboratory data with field implementation. The findings provide valuable recommendations on moisture control, appropriate equipment selection, and operator training to improve soil compaction quality in future construction projects.

Abstract

Bendungan urugan batu sangat dipengaruhi oleh fluktuasi muka air waduk, yang berdampak pada tekanan air pori, tegangan efektif, dan stabilitas lereng. Studi ini mengevaluasi stabilitas lereng pada tiga kondisi operasi utama: Muka Air Minimum (MAM), Muka Air Normal (MAN), dan Muka Air Banjir (MAB), serta kondisi transien berupa kenaikan muka air cepat (rapid rising) dan penurunan muka air cepat (rapid drawdown). Analisis rembesan dilakukan dengan pendekatan steady-state untuk kondisi MWL, NWL, dan FWL, serta pendekatan transien untuk rapid rising dan rapid drawdown menggunakan metode elemen hingga. Faktor keamanan dihitung menggunakan metode Morgenstern–Price. Hasil analisis menunjukkan bahwa pada kondisi steady-state, faktor keamanan lereng hulu masing-masing adalah 1,95 (MWL), 2,35 (NWL), dan 2,39 (FWL), sedangkan lereng hilir tetap stabil dalam kisaran 1,99–2,00 karena aliran rembesan tidak menembus inti kedap air. Pada kondisi rapid drawdown, faktor keamanan menurun akibat ketidakseimbangan antara tekanan hidrostatik dan tekanan air pori internal, sedangkan selama rapid rising faktor keamanan meningkat karena adanya tambahan tahanan dari tekanan hidrostatik. Seluruh nilai faktor keamanan memenuhi standar minimum yang dipersyaratkan, sehingga struktur dinyatakan stabil pada semua skenario operasi.

Abstract

The development of irrigation networks is a strategic effort to enhance food security by increasing land productivity and farmers’ income. However, investment decisions for irrigation infrastructure require comprehensive economic feasibility evaluations to ensure that the resulting benefits outweigh the associated costs. This study aims to assess the economic feasibility of an irrigation network development project in Southeast Sulawesi by considering key investment indicators and future economic uncertainties. The analytical methods employed include the calculation of Net Present Value (NPV), Internal Rate of Return (IRR), Benefit Cost Ratio (BCR), and Payback Period over a 25-year project life cycle, as well as a sensitivity analysis by considering potential changes in investment cost and interest rate by ±25%. The results indicate that the irrigation development project is financially feasible, with an NPV of IDR 5,302.06 million, an IRR of 9% which exceeds the 6% discount rate, a BCR of 1.30, and a Payback Period achieved in the 15th year of operation. Sensitivity analysis confirms that the project remains feasible even under increased cost or interest rate scenarios; however, it is more sensitive to changes in construction cost. Therefore, the irrigation network project is not only economically viable under baseline conditions but also demonstrates strong resilience against economic uncertainties, making it a suitable priority for agricultural infrastructure development in the region.
