Abstract

Occupational Health and Safety (OHS) is a crucial aspect of construction project management to minimize the risk of work-related accidents that may hinder project completion. This study aims to analyze, evaluate, and design a risk management model using the Hazard Analysis Method. The research was conducted through literature studies and direct observations to identify existing risk variables. Data testing employed validity and reliability tests to ensure response consistency, where an R calculated value of ≥ 0.6 indicated high reliability. Once valid and consistent data were obtained, the analysis was carried out using a risk matrix to determine the probability and impact levels of risks. The findings indicate that workplace accidents in construction projects can be classified based on resource categories with varying risk levels. The implementation of OHS policies, regular training, and scheduled supervision has proven effective in reducing the risk of work-related accidents. Therefore, proper OHS risk management can enhance workplace safety and improve the efficiency of construction projects.

Abstract

Many problems may arise during the execution of construction projects as a consequence of risks, and these problems may lead to substandard performance, substandard quality, and substandard work results. Knowing how risk management is applied to construction projects and what technical risk factors occur most frequently during the execution of work in the field are the main objectives of this study. The spillway construction of the Bulango Ulu dam project is the subject of this research, which aims to identify, analyze, and respond to potential risks. Consultants, supervision contractors, and construction management are the research subjects who measure risk variables and take preventive measures. Assessing risk variables through surveys and weighing the relative importance of various activities according to the Index of Relative Importance (IKR). After reviewing the data, we have identified five risk factor variables that significantly impact the Bulango Ulu dam spillway project. These factors include incorrect dimensioning (length, width, and height), incorrect time estimation, out-of-specification concrete quality, use of incorrect execution methods, and errors in reinforcement (iron dimensions, iron spacing, and iron quality).

Abstract

The implementation of infrastructure development in Indonesia has grown rapidly in recent years, particularly in the context of its status as a developing country. One major project receiving attention in Gorontalo Province is the construction of the Bulango Ulu Dam. However, this project has faced delays in completion, which necessitates an in-depth analysis to optimize both time and cost. This study aims to analyze the project’s work network to identify the critical path and evaluate time and cost efficiency through the application of a crash program using additional overtime hours. The research was conducted at several project locations: Tulova Village, Owata Village, and Mongiilo Village in Bone Bolango Regency, Gorontalo Province. The study employed the crash program method and utilized Microsoft Project and Microsoft Excel for data processing. These tools supported the identification of critical tasks and the analysis of overtime productivity, crash duration, cost slope, and post-crash program time and cost efficiency. The analysis revealed that critical tasks in the Bulango Ulu Dam construction include drilling and grouting, stockpile work, dam top miscellaneous work, cleaning, and jetty trash boom installation. Time efficiency resulting from overtime additions was found to be: 10% (1 hour), 16.90% (2 hours), 22.62% (3 hours), 26.67% (4 hours), and 30% (5 hours). Meanwhile, cost efficiency peaked at 2.58% with 4 hours of overtime. These findings suggest that the optimal scenario for time and cost efficiency in hoarding work is achieved by adding 4 hours of overtime.

Abstract

Heavy equipment plays a crucial role in ensuring the smooth and timely execution of construction projects. Inaccurate analysis of heavy equipment productivity and poor selection of equipment can lead to project delays and cost inefficiencies. This study aims to analyze the productivity of heavy equipment used in the main embankment work of the Bulango Ulu Dam, determine the estimated duration of work completion, and evaluate alternative efficiency strategies. A descriptive qualitative approach was employed, with a focus on excavators and dump trucks used in four categories of embankment excavation work: core, fine filter, coarse filter, and rock. The results show that the productivity of excavators in core embankment excavation reached 790.65 m³/hour, with a work duration of 69 days, while dump trucks recorded 820.50 m³/hour with 66 days of work. For fine filter embankment excavation, excavators achieved 779.24 m³/hour (32 days), and dump trucks 530.40 m³/hour (48 days). In the coarse filter embankment excavation, excavator productivity remained at 779.24 m³/hour (34 days), while dump trucks reached 511.20 m³/hour (52 days). In rock embankment excavation, excavator productivity was 898.00 m³/hour (394 days), and dump trucks 561.20 m³/hour (631 days). Based on the efficiency comparison, Alternative 2 is recommended as it provides a significant reduction in project duration with a relatively minimal cost increase compared to Alternative 1. These findings highlight the importance of accurate equipment planning to optimize project performance in terms of time and cost.

Abstract

The rapid growth of population has significantly increased the demand for housing, leading to the acceleration of residential construction projects. In this context, the efficiency of project scheduling methods plays a critical role in ensuring timely delivery and optimal resource utilization. This study aims to compare the effectiveness of the Line of Balance (LoB) and the Precedence Diagram Method (PDM) in the construction of the Citra Agrindo III Housing project. Employing a descriptive approach and utilizing secondary data such as S-curves and project time schedules, the research provides a detailed analysis of each method’s strengths and limitations. The findings reveal that the PDM method results in a shorter project duration, completing construction in 119 days, which is 4 days faster than the LoB method, requiring 123 days. This indicates that PDM is more effective in projects where task dependencies and sequencing play a significant role, as it clearly maps the relationships between activities. On the other hand, LoB demonstrates its superiority in managing repetitive tasks, ensuring smoother resource allocation and workflow consistency across housing units. The results highlight that both methods possess distinct advantages depending on project characteristics. Thus, project managers are encouraged to select scheduling methods that align with the nature of the project to achieve greater efficiency in both time and cost management. This comparison contributes to the broader understanding of construction project management and provides practical insights for improving scheduling strategies in the residential sector.
