Abstract

Effective project management is crucial for the successful completion of construction projects, including the construction of a dormitory at SMA Muhammadiyah 3 Tulangan. Challenges such as design changes, adverse weather conditions, and limited labor resources impact the project's progress. The Earned Value Method is used to monitor project performance by analyzing indicators like BCWS, BCWP, ACWP, SV, CV, SPI, and CPI. This analysis shows that the project initially experienced delays and exceeded budget costs, but the situation improved significantly over time. Despite weekly variations in costs, the project remained on a financially manageable track. The conclusion from this analysis is that while the project faced time delays, cost performance remained under control. Recommendations for improvement include more thorough planning, better resource management, and quicker responses to changes.

Abstract

The implementation of the Situbondo – Ketapang – Banyuwangi Road and Bridge Preservation Project experienced changes in the area being worked on, requiring additional design. Issues arose when the overlay asphalt mix work was halted to await test results for Aspal Modiv PG – 70 from the Pusjatan Bandung Road Materials Laboratory, causing a delay in the 40th week by -0.813%. Delays primarily occurred in the AC - WC and AC - BC asphalt work, affecting project performance. A cost and time analysis was necessary to address this issue. The Earned Value Method (EVM) was used to determine the project's duration and cost until initial handover. The study results indicated that the project cost performance with a CPI > 1 was good, but an SPI of 0.983 < 1 indicated delays. The estimated final project cost is Rp 112,439,121,070.91, with an estimated completion time of 453 days, 3 days longer than the planned schedule.

Abstract

Construction project management prioritizes the achievement of three main objectives: cost, quality, and time. This study evaluates a road widening project in Mojokerto Regency with a target completion time of 150 days. To prevent delays and cost overruns, researchers used the Earned Value method to identify early warnings regarding project performance. This method integrates time and cost values through measurements of 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 research findings show that additional costs required (ETC) reached Rp 3,276,704,110.14, with additional time (ETS) up to week 12 being 87 days. The change in project costs (EAC) reached Rp 3,961,767,811.01 from the contract cost, while the project completion time (EAS) was 171 days. The analysis indicates that the construction service provider has implemented an efficient implementation method with consistent supervision, ensuring the smooth progress of the project.

Abstract

This research investigates cost waste in detailed engineering design for the Syifaul Qulub Surabaya Islamic Boarding School construction project, aiming for on-time, on-budget completion. Utilizing a Lean Construction approach, the study analyzes waste reduction in this densely populated, limited-access urban environment. Primary data from questionnaires were processed to weigh waste in each activity, followed by value stream analysis tools, including Process Activity Mapping, to identify Value-Added (VA) and Non-Value-Added (NVA) activities. The findings revealed that waiting was the primary cause of waste, contributing to 41.8% of critical waste and a 33-day project delay. Root causes included material procurement issues, transportation challenges, and equipment problems. Waste accounted for 21% of all project jobs, categorized as Unnecessary Movement (13.7%), Transportation (12.2%), Material Defects (11%), Storage (10.9%), and Overproduction (6.8%). By addressing these wastes through targeted Lean interventions, the research suggests a potential project acceleration of approximately 16.5% (33 days) and a cost reduction of 5-10% by optimizing resource use and minimizing material waste. These results demonstrate the practical benefits of Lean Construction in mitigating inefficiencies and delays in challenging urban builds.

Abstract

The development of transportation infrastructure plays a pivotal role in supporting regional economic growth, particularly in areas undergoing rapid industrial and residential expansion. This study aims to conduct a comparative analysis between rigid pavement (concrete) and flexible pavement (asphalt) in terms of cost efficiency and implementation time on the Kedamean Sidoraharjo Randegan road section in Gresik Regency, East Java. The region’s strategic position, reinforced by the operation of the Krian Legundi Bunder Manyar (KLBM) toll road, has significantly increased traffic flow, thereby creating an urgent need for durable and sustainable road infrastructure. This research employs a quantitative descriptive approach by integrating traffic projections (Average Daily Traffic or LHR) for the 20th and 40th year horizons, CESAL calculations (Cumulative Equivalent Standard Axle Load), and pavement structure design using the MDPJ 2017 method for flexible pavement and Pd T-14-2003 for rigid pavement. Additionally, cost estimations are based on regional unit prices issued by the Gresik Regency Public Works Department. Findings indicate that although flexible pavement offers shorter construction time and lower initial costs, rigid pavement proves more cost-effective in the long run due to its durability and lower maintenance needs. The study also highlights that utilizing existing pavement layers can reduce construction costs by up to 10%, aligning with sustainable infrastructure practices. The results are expected to serve as a practical guideline for civil engineering practitioners and local governments in making strategic decisions regarding pavement type selection based on traffic intensity, budget availability, and long-term development goals.

Abstract

Margomulyo Street is in Asemrowo District, which is an area in West Surabaya that is famous for its industrial and warehouse complexes. The dense traffic of heavy vehicles such as trailers and other logistics trucks around industrial areas is the main cause of road pavement structures becoming susceptible to damage, including cracks, holes, and deformation. To maintain the pavement structure at the planned service level, a series of actions are called maintenance and repair. Therefore, to evaluate more deeply the condition of the road pavement, the Pavement Condition Index (PCI) method is used. Based on the results of the visual survey, there are several damages and percentage values, namely Weathering and Raveling (46,94%), Rutting (26,35%), Alligator Cracking (11,68%), Corrugation (5,17%), Longitudinal & Transverse Cracking (3,36%), Block Cracking (3,20%), Depression (1,30%), Potholes (1,07%), Patching & Utility Cut Patching (0,66%), Bleeding (0,24%), dan Edge Cracking (0,04%). And based on the results of data analysis, the PCI value on Margomulyo Road is 56.21% (Good).

Abstract

Evaluasi terhadap perkiraan biaya dan waktu akhir proyek sangat diperlukan untuk mengukur apakah proyek tersebut dapat diselesaikan sesuai dengan anggaran dan jadwal yang telah ditetapkan sebelumnya. Perhitungan Perkiraan biaya dan waktu akhir pada proyek rehabilitasi Gedung Gelanggang Olahraga Segiri di Kota Samarinda menggunakan metode Earned Value Method (EVM). Evaluasi dilakukan dengan menghitung Estimate At Complete (EAC) untuk proyeksi biaya dan Estimate At Schedule (EAS) untuk perkiraan waktu penyelesaian proyek. Hasil analisis menunjukkan bahwa EAC mengalami fluktuasi, dimulai dari Rp 44.648.760.330,58 pada minggu pertama Juli dan meningkat hingga Rp 52.630.845.855,14 pada minggu ke-15 November. Perubahan ini dipengaruhi oleh peningkatan Actual Cost of Work Performed (ACWP) yang mencapai Rp 31.173.250.000,00 pada minggu ke-15, serta penurunan Estimate To Complete (ETC) yang mencerminkan penyesuaian biaya. Meskipun EAC menunjukkan tren kenaikan dari Juli hingga Oktober, terdapat penurunan pada bulan November yang menandakan adanya perbaikan dalam pengelolaan biaya proyek. Di sisi waktu, EAS menunjukkan bahwa proyek sempat berjalan lebih cepat dari jadwal pada minggu pertama hingga ketiga, dengan nilai EAS berkisar antara 16,57 dan 16,41. Namun, mulai minggu ke-4 hingga ke-6, EAS meningkat signifikan, mencapai 28,80 pada minggu ke-6, mencerminkan adanya keterlambatan. Meskipun ada penurunan EAS pada minggu ke-14 dan ke-15, proyek masih menunjukkan keterlambatan signifikan dibandingkan dengan jadwal yang direncanakan. Temuan ini menekankan pentingnya evaluasi lebih lanjut dalam manajemen waktu dan alokasi sumber daya untuk meminimalisir keterlambatan dan memastikan proyek selesai sesuai target.
