Abstract

In construction project management, achieving three main goals, namely cost, quality, and time, becomes the primary focus. This study aims to evaluate a road widening project in Mojokerto Regency with a target completion time of 150 days. To prevent delays and cost overruns, researchers adopted the Earned Value method as a tool to identify early warnings regarding project performance. This method integrates cost and time measurements through indicators such as Cost Variance (CV), Schedule Variance (SV), Cost Performance Index (CPI), Schedule Performance Index (SPI), Estimated at Completion (EAC), and Estimated Schedule at Completion (EAC). The analysis results show that the additional costs required (ETC) amounted to Rp 3,276,704,110.14, with an estimated additional time (ETS) up to the 12th week being 87 days. The project's cost change (EAC) reached Rp 3,961,767,811.01 from the contract cost, while the estimated project completion time (EAS) was 171 days. These findings indicate that the construction service provider has implemented an efficient execution method with consistent monitoring, ensuring the smooth progress of the project.

Abstract

The reconstruction of the Surabaya-Gempol Toll Road underscores the critical role of effective project management in large-scale infrastructure projects, particularly in ensuring time and cost efficiency. This study employs the Earned Value Method (EVM) to evaluate project performance through the analysis of Schedule Variance (SV) and Cost Variance (CV). These indicators provide a comprehensive assessment of the project's adherence to its planned schedule and budget. The findings reveal that the project faced initial schedule delays due to logistical and technical challenges, resulting in negative SV values during the early weeks. These delays were primarily caused by weather conditions, late material deliveries, and coordination issues among project stakeholders. However, corrective measures, including extended working hours, additional labor deployment, and optimized scheduling, successfully addressed these issues, leading to positive SV values towards the end of the project. The CV analysis highlighted consistent cost efficiency throughout the project. Positive CV values dominated the majority of the timeline, reflecting effective cost control and resource management. Despite minor cost deviations due to unanticipated repairs and equipment maintenance, the project demonstrated an ability to maintain overall financial performance within the budget framework. This study emphasizes the significance of data-driven decision-making and proactive variance management in achieving project goals. By leveraging SV and CV analyses, infrastructure projects can better anticipate potential issues, implement timely corrective actions, and improve overall performance. The results of this research offer valuable insights for managing similar large-scale projects, contributing to enhanced efficiency and sustainable development in Indonesia's infrastructure sector.

Abstract

This study investigates the effectiveness of Social Media Marketing Activities (SMMA) on purchase intention, using Fitfuel as a case study. The research examines the impact of SMMA on brand awareness and customer trust, and how these two variables influence purchase intention. A quantitative approach was employed, using online questionnaires distributed to 200 respondents, supported by interviews with Fitfuel's management. The external and internal environment were analyzed through PESTEL, Porter’s Five Forces, competitor analysis, STP, Marketing Mix, VRIO, and SWOT. Results show that SMMA has a significant positive effect on both brand awareness and customer trust. In turn, both brand awareness and customer trust positively influence purchase intention. However, communication between consumers and the brand (as part of SMMA) was found to have a less significant effect compared to other indicators. The study presents a TOWS matrix and implementation plan to offer strategic actions for Fitfuel to optimize its digital marketing, strengthen brand perception, and increase conversion. This research contributes to understanding how digital marketing components affect customer behavior in the health food sector.

Abstract

In the Kandya House Villa Construction project in Ubud, Bali, there was a delay with a time deviation of -11.97%. This delay has the potential to cause the completion time of the work, which according to the contract is scheduled for 53 weeks, to be exceeded. To evaluate the time and cost performance in this project, the Earned Value method was used. This method utilizes three main indicators, namely Actual Cost of Work Performed (ACWP), Budgeted Cost of Work Performed (BCWP), and Budgeted Cost of Work Scheduled (BCWS). The results of the analysis show that the project time performance has decreased, characterized by a Schedule Variance (SV) value of -Rp 375,265,411.62. This value reflects a significant difference between planned and completed work. In addition, the Schedule Performance Index (SPI) was recorded at 0.772, which means that time efficiency only reached 77.2% of the planned schedule. As a result, the projected completion of work using the Estimate to Schedule (ETS) and Estimate at Schedule (EAS) indicators increased to 421 days or equivalent to 60.090 weeks, far exceeding the contract duration. In terms of cost, the analysis shows suboptimal performance, with a Cost Variance (CV) value of -Rp 48,700,590.06. This indicates that the actual costs incurred were higher than the planned budget for the completed work. In addition, the Cost Performance Index (CPI) value was recorded at 0.963, which means that the efficiency of budget utilization only reached 96.3%.
