Abstract

In Civil Engineering work, precisely determining the volume of excavation and embankment is critical to ensuring accurate work planning, efficient pricing, and seamless project execution. The estimated cost of the project budget is determined through volume calculations. This investigation aims to determine the volume of excavation and embankment by employing both Total Station and Waterpass, as well as AutoCAD Civil 3D software. The Citra City Sentul Housing Road was the subject of the study. The Average Cross-section is employed to determine the volume of excavation and embankment, and the results are analyzed using the standard deviation value. The volume of excavation and embankment is greater when calculated using Total Station than when calculated using Waterpass. There is a slight discrepancy in the standard deviation of the two instruments, specifically in the volume of excavation with Total Station (0.03%) and Waterpass (0.02%), as well as in the volume of embankment (0.02%) and 0.01%, respectively. Consequently, Waterpass has been demonstrated to be more precise than Total Station, despite Total Station being more expeditious in the measurement process.

Abstract

This study investigates the enhancement of clay soil properties by adding calcite and silica fume to address challenges such as low bearing capacity and high compressibility. A total of 51 soil samples were prepared, with 3 samples for each variant, treated with 5% calcite and varying silica fume concentrations (6%, 8%, 10%, 12%). The samples were cured for 0, 3, 7, and 14 days. Unconfined compressive strength (UCS) tests were conducted to evaluate the mechanical properties. Results revealed significant improvements, with UCS increasing from 0.412 kg/cm² in untreated soil to 1.724 kg/cm² in samples treated with 5% calcite and 12% silica fume after 14 days of curing. These values meet or exceed typical strength requirements for construction purposes, reinforcing the effectiveness of calcite and silica fume as stabilizing agents. The enhancement is attributed to the pozzolanic reaction between the additives and the soil, forming calcium silicate hydrate (CSH) and strengthening the soil's microstructure. The findings indicate that calcite and silica fume effectively improve soil stability, offering a promising solution for geotechnical applications. Future research should focus on evaluating the long-term stability of treated soils under various environmental conditions and exploring additional curing methods to optimize the chemical reactions further.

Abstract

Labor productivity is the main parameter in the success of a construction job. This study aims to analyze the level of productivity and the level of Labor Utilization Rate (LUR) in plastering work using the work sampling method, and the most effective time correlation between morning and afternoon. This research was conducted by direct observation for 3 days. The results showed that the highest productivity value was 14.30 m²/hour in the afternoon, and the lowest productivity value was 6.86 m²/hour in the morning. The Labor Utilization Rate (LUR) values in the morning and afternoon were 57.9% and 65.9%, indicating that the afternoon time was more effective than the morning time. However, there was a significant difference in productivity between morning and afternoon time overall, and it can still be categorized as effective with a Labor Utilization Rate (LUR) value of 61.9%, which exceeds 50%.

Abstract

This aim of this study is to evaluate the impact of climate change on the hydrological, hydraulic, and slope stability conditions of the Tukul Dam in the Kali Telu watershed, Pacitan. The methodology includes hydrological analysis using the Log Pearson Type III distribution, flood discharge estimation with the HSS Nakayasu method, and hydraulic simulation using HEC-RAS to determine maximum floodwater elevation. Slope stability was analyzed with Geostudio using the Bishop method to determine the factor of safety (FS). The results indicate that the maximum 1,000-year rainfall reaches 550.82 mm, generating a peak discharge of 1,152.26 m³/s, exceeding the design discharge of 380.73 m³/s. Hydraulic simulation showed a floodwater elevation of +183.59 meters, while slope stability analysis confirmed that all FS values remained above the safe limit of 1.30, ensuring dam stability. This study integrates updated hydrological data with geotechnical modeling to enhance understanding of dam resilience under extreme conditions. Recommendations include spillway capacity improvements, early warning systems, and continuous monitoring to mitigate future flood risks.

Abstract

Utilization coral limestone aggregate as a sustainable alternative in the construction industry has become critical in order to reduce reliance on traditional aggregates. Previous research Lukas A. Y, et al. revealed that concrete with fine aggregate of zone IV gradation and coarse aggregate coralline limestone replacing 25% coarse aggregate gravel can raise compressive strength concrete to 33.37 MPa. It is predicted that fine aggregate with a zone IV gradation, which has small particle sizes, will fill voids in concrete, enhancing its strength. However, increasing coralline limestone component to 50% reduces concrete compressive strength. This suggests that macroscopically, fine particles of zone IV grading have yet to make a significant contribution to increase in concrete compressive strength. Therefore, the current study attempts to optimize concrete mix employing fine aggregate with zone II gradation and its impact on concrete compressive strength. Meanwhile, study employs a laboratory experimental test for compressive strength and ultrasonic pulse velocity, with a target concrete compressive strength of 30 MPa. Study found concrete with coralline limestone content of 0%, 5%, 25%, 50%, and 75%, as well as fine aggregate from zone II grading, had 28-days compressive strengths of 20.27 MPa, 22.10 MPa, 23.80 MPa, 24.42 MPa, and 18.19 MPa. Fine aggregate in Grading Zone II reduces concrete strength.

Abstract

Enhancing efficiency, minimizing waste, and improving project productivity are key objectives in Lean Construction. This study explores the impact of Lean Construction implementation at PT PP by examining the correlation between Planned Percentage Complete (PPC) in the Last Planner System (LPS) and project performance, including productivity and cost efficiency. The research employs a descriptive statistical analysis method, with data collected through a self-assessment survey and an evaluation of the correlation between PPC and key project management factors. The results indicate that LPS implementation significantly enhances productivity, with a positive correlation between PPC values and project efficiency. Furthermore, waste analysis reveals that Waiting, Defect, and Overproduction are construction projects' most dominant waste categories. This study also identifies that Lookahead Planning within LPS is crucial in reducing constraints, positively impacting project timeliness and cost control. Consequently, the findings provide deeper insights into Lean Construction  implementation and offer strategic recommendations for companies to sustainably enhance efficiency and project performance.

Abstract

This research aims to analyze the comparative value of analytical rational methods in calculating the bearing capacity of pile foundations based on N-SPT data. The results of calculating the bearing capacity of pile foundations by analytical methods (Luciano Decourt & Quaresma, Meyerhof, Nakazawa, Terzaghi & Peck, Reese O'Neil, and Vesic & Tomlinson) will be compared to the results of CAPWAP analysis of PDA (Pile Driving Analyzer) tests. The results of this study show that the Meyerhoff (1956) method provides the highest tip bearing capacity values, while the Nakazawa (2000) method produces the highest blanket bearing capacity and total bearing capacity values compared to other methods. Comparison of the ratio of total bearing capacity to CAPWAP showed a range of values from 0,82 to 1,64 with the Terzaghi & Peak (1948) methods providing the highest ratio. The methods with the smallest to largest average comparison values are Nakazawa (2000), Meyerhoff (1956); Luciano Decourt (1982) & Quaresma (1978); Vesic (1977) and Tomlinson (1977); Reese O'neil (1999); Terzaghi & Peak (1948) with average comparison values against CAPWAP of 0.81; 0.88; 1.14; 1.56; 1.57; 1.64 respectively. The comparison of the total bearing capacity of the analytical method to the CAPWAP analysis that is closest to 1 is the Meyerhoff (1956) and Luciano Decourt (1982) & Quaresma (1978) method. Therefore, the most effective analytical methods in calculating the total bearing capacity of piles are Meyerhoff (1956) and Luciano Decourt (1982) & Quaresma (1978) methods.

Abstract

Expansive soils are highly susceptible to volumetric changes due to moisture fluctuations, which can significantly affect the stability and durability of structures. Therefore, their presence must be carefully considered during the planning and foundation design stages. Survey, field investigations, and lab tests show that soil up to 8 m deep has a plasticity index of 30%–65%. Swelling tests on samples from 1 m–3.5 m depths revealed swelling percentages of 0.545%–0.715% and pressures of 11.7 kPa–12.5 kPa, which are high for near-surface soil. XRD tests identified montmorillonite minerals, known for high activity and shrinkage, contributing to slope cracks and movement. Geotechnical analysis using finite element method shows that slope stability safety factors of 0.84 (static) and 0.62 (earthquake), below required thresholds of 1.5 and 1.1, respectively. The proposed reinforcement includes double-row soldier piles, connected by a capping beam. The slope surface will be graded downstream and reinforced with 1 m thick stone masonry. These measures are expected to increase safety factors to 1.72 (static) and 1.1 (earthquake), meeting safety standards.
