Abstract

Indonesia is a high seismic-risk region due to tectonic plate interactions, particularly along the subduction zone south of Java. The Cirebon area is also influenced by megathrust sources and local faults such as the Baribis Fault, posing significant seismic hazard. This condition requires building structures that are not only strong but also capable of maintaining adequate performance during earthquake loading. This study aims to assess the structural performance of a three-story office building through nonlinear static (pushover) analysis. Modeling was conducted in ETABS, referring to SNI 1726:2019, SNI 1727:2020, and SNI 2847:2019, with dead, live, and lateral loads applied incrementally until the structure reached an inelastic condition. The results show that the structure has adequate lateral capacity, with plastic hinge distribution dominated by the Immediate Occupancy (IO) level. Capacity spectrum transformation using FEMA 440 in the X direction produced stable results, while the Y direction yielded anomalous values requiring further validation. Overall, the structure tends to exhibit Immediate Occupancy performance, although the final global performance level cannot yet be conclusively determined. It is recommended that future analysis revalidate the Y-direction performance point and consider refining the plastic hinge modeling parameters to ensure more reliable performance evaluation results.

Abstract

Concrete is one of the most widely used construction materials due to its high compressive strength, good durability, and the availability of its constituent materials. However, the increasing demand for natural fine aggregate has led to excessive exploitation of natural resources, creating environmental concerns. Therefore, alternative materials are needed to partially replace fine aggregate. This study aimed to analyze the effect of partially substituting fine aggregate with Malang Sand and Stone Dust on the compressive strength of concrete with a design strength of 20 MPa and to determine the optimum mixture proportion. The research employed an experimental method conducted at the Civil Engineering Laboratory of Universitas Islam Lamongan UNISLA. Cylindrical concrete specimens measuring 15 cm × 30 cm were prepared using the mix design method based on SNI 03-2834-2000. The substitution levels of fine aggregate were 5% (2.5% Malang Sand + 2.5% Stone Dust), 10% (5% Malang Sand + 5% Stone Dust), and 15% (7.5% Malang Sand + 7.5% Stone Dust), with normal concrete used as the control mixture. The results showed that the average compressive strength of normal concrete was 20.52 MPa, while the 5%, 10%, and 15% substitution mixtures achieved compressive strengths of 19.85 MPa, 18.47 MPa, and 17.50 MPa, respectively. Increasing the substitution percentage of Malang Sand and Stone Dust tended to reduce the compressive strength of concrete. The 5% substitution mixture produced the best performance because its compressive strength was the closest to both the normal concrete and the target design strength of 20 MPa.

Abstract

One of the main challenges in construction project management is balancing implementation duration and total project cost. Time-Cost Trade-Off (TCTO) is a method used to analyze the relationship between time and cost in an effort to find the most efficient combination. This study aims to present the application of the TCTO method with a genetic algorithm (GA) approach as an optimization technique. The analysis results indicate that accelerating work duration can affect project costs. Analysis of direct and indirect cost graphs using the Time-Cost Trade-Off method demonstrates that accelerating time causes an increase in direct costs and a decrease in indirect costs, thus requiring a balance between the two to achieve project efficiency. These results demonstrate that this approach is capable of simultaneously presenting efficient alternative solutions and can be used as a reference for decision-making in the project planning stage. Consequently, the Genetic Algorithm (GA) has proven to be a practical and applicable method for solving Time-Cost Trade-Off problems in construction projects.

Abstract

Groundwater is used for various purposes, including in the agricultural sector. In this sector, groundwater plays an important role as a source of irrigation for agricultural land, especially during the dry season, when the water supply from the surface is insufficient for irrigation needs. The groundwater irrigation network is a channel system that flows groundwater from the pump building to the rice fields to be irrigated. This study aims to determine the irrigation water and piping needs in SDBW 198 Sumberanyar. The research method used is quantitative. The results of the calculation of the irrigation water needs of SDBW 198 per plot of land showed that the total irrigation water requirement was 39.49 liters/second. The discharge requirement of 39.49 liters/second is the sum of the needs of all plots if they are irrigated simultaneously. Meanwhile, the available pump discharge is 33.84 liters/second. Therefore, irrigation services are not planned simultaneously, but are carried out in turns based on plot groups so that the discharge requirements in each service period do not exceed the pump capacity. The design of the piped irrigation network can irrigate 23.03 hectares of rice fields using 6-inch PVC pipes for pipes P2, P6, P4, P5, P6, P7, P9, P12, 4-inch pipes for pipes P3, P5, P13, P14, P19, and 2-inch pipes for pipes P8, P10, P11, P15, P16, P17, and P18. The highest headloss simulation results were 6.05 m/km for pipe P2 and 8.13 m/km for pipe P6. Because the headloss in pipes P2 and P6 did not meet standards, two air valves had to be installed. The highest pressure simulation results occurred at J-TO1 with a value of 60.93 meters of water, while the lowest pressure was at J-17 with a value of 20.07. Therefore, the pressure simulation results using EPANET 2.2 software met all required criteria.

Abstract

The increase in traffic volume, particularly overloaded heavy vehicles, accelerates pavement deterioration before reaching its design life. This makes urban local roads vulnerable to premature damage due to axle loads exceeding design capacity. This study aims to analyze the effect of traffic loads on the remaining pavement service life on Jalan Swadaya, Mataram City, using the Bina Marga 2024 method. A quantitative approach was employed through analysis of Average Daily Traffic (ADT), Vehicle Damage Factor (VDF), and Cumulative Equivalent Single Axle Load (CESAL) under normal and actual conditions. Results showed cumulative CESAL under normal conditions was 94828 ESA, while under actual conditions it increased to 156175 ESA due to high traffic loads. This caused a significant decrease in Remaining Life (RL), where under normal conditions the pavement could achieve its 10-year design life, while under actual conditions service life was estimated at only 7.33 years, an accelerated reduction of 2.67 years compared to the design life. Under actual conditions, RL decreased to 7% in 2033 and -65% at the end of the analysis period, indicating the pavement had exceeded its design capacity and was no longer structurally feasible. Therefore, controlling overloaded vehicles and implementing heavy rehabilitation or reconstruction are necessary to maintain pavement performance.

Abstract

Uncertainty in project duration caused by weather conditions, resource availability, and labor productivity remains a common challenge in the construction industry, requiring a scheduling method capable of minimizing the risk of delays. This study aims to analyze the critical path and the probability of project completion in the construction project of the Environmental Agency (DLH) Office Building of Samarinda City using the Precedence Diagram Method (PDM) and the Program Evaluation and Review Technique (PERT). The project under study has a building area of 450 m² with a planned implementation duration of 180 calendar days. The research data were obtained from project documents and questionnaires distributed to 30 respondents with experience in the construction sector. The analysis was conducted using Microsoft Project 2019 to develop the project network and identify activities on the critical path. The results of the PDM analysis indicated that 53 out of 205 total work items were critical activities, with an estimated minimum project completion duration of 158 days; these activities directly affect the overall project completion time. Subsequently, the PERT method was employed to estimate the optimistic, most likely, and pessimistic durations of each critical activity and to determine the probability of completing the project within the planned schedule. The results showed that the probability of completing the project within 180 calendar days was 81%, indicating a high level of confidence consistent with the project's actual on-time completion in the field. The PDM method provides information on activities within the project's critical path, while the PERT method provides information on the probability of project completion according to the planned schedule, so the results of this analysis can serve as a reference for evaluating and controlling construction project schedules. Future research is recommended to consider a time-cost trade-off analysis on critical activities to evaluate the potential efficiency gains if the project is completed ahead of the planned schedule.

Abstract

Field supervisors play a crucial role in ensuring the successful implementation of construction projects, particularly in controlling the quality, time, and cost of work. The competence of field supervisors is a key factor in ensuring that the construction process runs in accordance with technical specifications, occupational safety standards, and applicable contract provisions. Therefore, competency standards referring to the Indonesian National Work Competency Standards (SKKNI) are needed as a reference in improving the quality of human resources in the construction sector. This study aims to identify competency factors that field supervisors must possess, measure the level of conformity of these competencies to the SKKNI, and analyze the relationship between competencies in the Indonesian National Qualification Framework (KKNI) levels 4–6 and 7–9 in construction projects at the Public Works and Spatial Planning Agency of Sijunjung Regency. This study uses a quantitative approach with a survey method by distributing questionnaires to 100 respondents consisting of contractors, supervisory consultants, and technical officials involved in the implementation of construction projects. Data analysis was carried out through validity and reliability tests, factor analysis, and Structural Equation Modeling (SEM). The results of the study indicate that field supervisor competency is formed from three main dimensions, namely technical and managerial competency, social and operational field competency, and professional work attitude. Of the 36 competency indicators analyzed, 72.22% are in the appropriate category and 27.78% are in the very appropriate category according to the SKKNI standards. In addition, the results of the structural analysis show that competency at KKNI levels 4–6 has a significant effect on competency at KKNI levels 7–9 with a coefficient of determination (R²) of 0.658. These findings indicate that the competency system is hierarchical and progressive and plays an important role in improving the quality of supervision and professionalism of workers in the construction sector.

Abstract

Significant and highly complex issues in the construction sector are currently a special and very important concern in reviewing the resolution of ongoing construction conflicts. Poor planning, unclear objectives, ineffective communication, and management and resource issues are the main causes of failure in construction projects. The most common problems are a) unclear inventory, b) irregular workflows, c) lack of employee training and competency development, d) lack of analytical data integration for communication, e) immature planning, unclear environment, poor budgeting, and inadequate risk management, f) unmeasurable targets, and g) a large number of human resources who are not yet competent in their respective fields. This inefficiency will certainly affect construction performance productivity, both from internal and external factors, thereby affecting project implementation, which requires us to provide quality management for the construction project itself and the community. The results showed that inventory management, information technology, training and development, data integration, and competent human resources had positive and significant effects on construction productivity. The proposed SEM model demonstrated an acceptable overall fit.

Abstract

Traffic congestion in Balikpapan City continues to increase due to rapid growth of private vehicle ownership, which is not proportional to available road capacity. To address this issue, the Balikpapan City Government has introduced the Balikpapan City Trans (BCT) Corridor B as a mass public transportation service expected to encourage people to shift from private vehicles to public transport. This study aims to analyze the effectiveness of Balikpapan City Trans Corridor B in reducing traffic congestion in Balikpapan City and to evaluate the relationship between BCT operational performance and traffic conditions. This research employed a quantitative descriptive approach through traffic surveys, field observations, public transport operational performance measurements (headway and load factor), and questionnaire distribution to 100 respondents selected using the simple random sampling technique. Data were analyzed based on the Indonesian Road Capacity Guidelines (PKJI) 2023 using traffic volume, road capacity, degree of saturation, level of service, headway, and load factor as the main indicators. The results indicate that the effectiveness of BCT Corridor B remains relatively low. Most road segments recorded degree of saturation values ranging from 0.72 to 0.87 with Level of Service (LOS) D–E, the average headway exceeded 21 minutes, private vehicles remained the dominant mode of transportation, and bus occupancy levels were not yet optimal. Consequently, the contribution of BCT in reducing traffic congestion has not been significant. Therefore, improving service quality through additional buses, shorter headway, optimized operational schedules, and stronger policies encouraging a shift from private vehicles to public transportation is recommended.

Abstract

Vacuum Consolidation is one of the effective soft soil improvement techniques; however, its implementation involves the use of heavy equipment, high-pressure instruments, and complex geotechnical working environments, which may generate various Occupational Health and Safety (OHS) hazards. This study aims to identify potential hazards, assess risk levels, and formulate control measures for soil improvement works using the Vacuum Consolidation method. The analysis was conducted using the Hazard Identification and Risk Assessment (HIRA) approach based on a standard risk assessment matrix. Data were collected through field observations and literature reviews. The hazard identification results revealed several critical potential incidents, including unstable Prefabricated Vertical Drain (PVD) hydraulic rigs that may overturn on soft ground, workers coming into contact with uninsulated live electrical cables, and unauthorized contact with pumps or electrical control panels that may result in fatal electric shock. The initial risk assessment classified the identified hazards into low, medium, high, and extreme risk categories. Through the implementation of mitigation measures encompassing engineering controls, administrative controls, and strict compliance with Personal Protective Equipment (PPE) requirements, the residual risk level is projected to be reduced to an acceptable level. This study is expected to serve as a guideline for the implementation of Occupational Health and Safety Management Systems in similar geotechnical projects to minimize workplace accidents and optimize project productivity.
