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 aims to analyze the influence of building construction project financing, which includes contract value, project duration, and number of floors, on human resource costs (Expert Costs, Skilled Labor Costs, and Worker/Mandor Costs) in building construction projects within the Dili City Government Office. The research focuses on 20 building projects in the Dili City Government Office environment. Using project report documents as data, the independent variables in this study are contract value, project duration, and the number of floors, while the dependent variables are the costs associated with experts, skilled labor, and workers/mandors/laden. The study employs multiple linear regression analysis to assess the relationship between these variables. The results show that the contract value has a significant partial effect on human resource costs, including expert costs, skilled labor costs, and worker/mandor costs. This indicates that a higher contract value influences the allocation of human resource costs in building construction projects. In conclusion, the study highlights the importance of managing contract value, project duration, and the number of floors to optimize human resource costs and ensure efficient project completion.

Abstract

Kampung Kasai merupakan kampung nelayan yang terus berkembang dari kampung tertinggal menuju kampung berkembang. Seiring dengan pertumbuhan itu tuntutan kebutuhan prasarana dan sarana air bersih terus meningkat. Kebutuhan air bersih mencapai puncaknya pada saat musim kemarau tiba yang menyebabkan tekanan besar pada pasokan air bersih yang berakibat ketidakcukupan untuk kebutuhan sehari-hari masyarakat. Perlu dilakukan analisis mendalam mengenai strategi pengelolaan sumber air bersih yang efektif untuk mengatasi kekurangan pasokan pada musim kemara. Metode penelitian menggunakan Analisis proyeksi jumlah penduduk dan Pengukuran Debit pada Sumur Pengambilan. Dilakukan uji pumping test di lokasi sumur setelah sebelumnya dilakukan pengistirahatan selama ±24 jam kepada sumur bor yang akan di uji pemompaan. Dari uji pumping test selama 24 jam nonstop didapatkan debit konstan sebesar 2 liter/dt. Uji Pemompaan dilaksanakan pada tanggal 5 Maret 2024 sampai 11 Maret 2024 dengan metode constant rate test menggunakan pompa yang tersedia di lokasi pengujian. Uji pemompaan dilakukan secara terus menerus selama waktu tertentu dan kedudukan muka air tanah mengalami kondisi relatif stabil pada kedalaman tertentu, kemudian pompa dimatikan. Adapun dari uji pumping test selama 24 jam nonstop didapatkan debit konstan sebesar 2,32 Lt/detik. Sehingga disimpulkan bahwa uji pemompaan lebih besar dari perhitungan potensi air tanah.

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.
