Abstract

Road infrastructure is essential for supporting transportation, fostering economic growth, and enhancing community mobility. However, the Bungur-Kedoyo road construction project in Tulungagung has faced challenges in time and cost management, impacting overall project performance. This study aims to evaluate the project's time and cost performance using the Earned Value Method (EVM), a robust tool that compares planned work, completed work, and actual costs to provide a comprehensive performance analysis. Data from the 25th-week project report revealed delays, with a Schedule Variance (SV) of -Rp. 315,481,514.90 and a Schedule Performance Index (SPI) of 0.970, indicating slower progress than initially planned (SPI < 1). These results highlight the need for improved project scheduling and enhanced control mechanisms to mitigate delays and manage costs effectively. By identifying inefficiencies and areas requiring intervention, the study provides actionable recommendations for improving project management practices. It concludes that integrating EVM into time and cost control processes can significantly enhance project efficiency and reliability. This research contributes to advancing infrastructure development by offering insights that can be applied to similar projects, ensuring timely and cost-effective delivery while promoting sustainable growth in the road construction sector.

Abstract

The construction of the Probolinggo-Banyuwangi Toll Road Package 2 is a strategic project that plays a critical role in enhancing infrastructure connectivity in East Java. However, it faces significant risks arising from both internal and external factors. Internal challenges include limited availability of skilled manpower, inadequate heavy equipment, and poor project coordination, which hinder project efficiency. External challenges, such as fluctuating raw material prices, regulatory changes, and adverse weather conditions, further complicate the implementation of the project. These risks, if unmanaged, could result in delays, cost overruns, and compromised project quality. This study focuses on identifying key risk factors and developing effective mitigation strategies through qualitative and quantitative risk analysis. Priority risks, including material delivery delays, frequent design changes, and financial instability, were identified as critical to the project’s success. The findings underline the importance of proactive and structured risk management approaches, as guided by frameworks like ISO 31000 and AS/NZS 4360, which emphasize early risk identification, assessment, and mitigation during the planning phase. Furthermore, the research highlights the necessity of strong coordination among stakeholders, from government agencies to contractors and subcontractors, to mitigate risks collaboratively. Developing a risk-conscious organizational culture is crucial to ensuring project efficiency, not only in terms of cost but also in time and quality management. By implementing a systematic and integrated risk management framework, the Probolinggo-Banyuwangi Toll Road Package 2 project can serve as a model for managing risks effectively in large-scale construction projects. This study provides valuable insights for future infrastructure developments in Indonesia, emphasizing the importance of robust risk management practices for achieving project sustainability and success

Abstract

Delays in construction projects often result in resource waste and conflicts among stakeholders. This study focuses on the application of Lean Construction within the "Improve" phase of the Lean Six Sigma framework as a solution to minimize project delays. Lean Construction techniques, particularly Value Stream Mapping (VSM), are utilized to identify and eliminate inefficiencies in the construction process. The implementation of these methods in a case study of PT Golden Union Oil's refinery project in Sidoarjo demonstrated a significant reduction in waste by 57.49%. This achievement underscores the effectiveness of Lean Construction in streamlining project activities and enhancing overall efficiency. By integrating Lean Construction principles into the DMAIC framework, this approach offers systematic and practical strategies for addressing delays in construction projects. The findings contribute to the broader understanding of how innovative management techniques can optimize project delivery timelines and resource utilization in the construction industry.

Abstract

This study aims to analyze the mitigation of factors that cause delays in the Probolinggo City Square construction project, a project that faces challenges in implementation and completion. Delays in construction projects can have various negative impacts, including increased costs, time losses, and reduced quality of project outcomes. Thus, project mitigation becomes the main core in this research. Through this research, it is shown that there are several mitigation measures, such as digitization of administrative processes to speed up approval of materials, improved coordination between parties to reduce conflicts and uncertainties, and more careful planning for additional work and identification of work. In addition, workforce training and the use of more advanced project management technology can improve the efficiency of project implementation. The results of this study are expected to be a reference for parties involved in construction projects, especially in managing the risk of delay. With the implementation of appropriate mitigation measures, construction projects can be more efficient in terms of time, cost, and quality, thus providing maximum benefits for all parties involved.

Abstract

This study aims to analyze the impact of elevator installation delays on the schedule and budget of a 10-story office building construction project in Gresik. By comparing two scenarios—on-time elevator work versus delayed elevator work—this research uses a comparative analysis approach based on project documentation, interviews with stakeholders, and cost and time data. The findings reveal that delays in elevator work significantly affected the overall project timeline, causing a shift in the schedule and necessitating changes in structural methods, particularly the use of steel instead of concrete for the separator beams. This change expedited construction but increased costs substantially. The study also highlights the cascading effects of these delays, which led to further adjustments in the building's structure and increased labor and material costs. The research emphasizes the importance of early-stage planning, coordination, and the adoption of advanced project management techniques, such as Building Information Modeling (BIM), to minimize risks and ensure timely project completion. In conclusion, the study provides valuable insights into how elevator delays can disrupt construction projects and recommends strategies to mitigate such risks in future developments.

Abstract

PT. Candi Loka Jamus switched to using micro hydro power plants to meet its electrical energy needs because of the high operational costs and environmental impact of fuel oil power plants. However, during the dry season, the micro hydro power plant is unable to produce enough energy to meet the needs, which could lead to damage of its components and decreased performance. To address this issue, the energy potential of the micro hydro power plant was calculated using operational time simulation and season time simulation. The rain data was analysed using the double mass curve analysis method and arithmetic mean method to calculate the discharge throughout the year. The dependable discharge was calculated using the F.J. Mock method and the basic year method, and the physical potential formula was used to calculate the energy potential. Based on the calculations, the dependable discharge energy potentials of Q80, Q70, Q50, and Q30 were found to be 569,173.91 KWh, 614,737.01 KWh, 589,640.81 KWh, and 619,855.44 KWh, respectively. The efficient operating time of the micro hydro power plant was determined based on the Q80 dependable discharge energy potential with a simulation of operational time. The plant should be active from January 1 to August 15, deactivated for maintenance purposes from August 16 to October 31, and reactivated from November 1 to December 31. With an active period of 287 days, the Jamus micro hydro power plant has an energy potential of 488,732.17 KWh in one year.

Abstract

Penelitian ini bertujuan untuk menghasilkan model elevasi yang akurat pada segmen belokan Sungai Wonokromo melalui integrasi fotogrametri udara berbasis Unmanned Aerial Vehicle (UAV) dan pengukuran batimetri. Banjir di wilayah Surabaya Selatan dipengaruhi oleh kombinasi pasang surut, penyempitan geometri sungai, serta sedimentasi pada tikungan yang menurunkan kapasitas aliran, sehingga diperlukan informasi topografi dan batimetri yang lebih detail. Akuisisi data dilakukan menggunakan Unmanned Aerial Vehicle (UAV) yang menghasilkan 653 citra dengan 20 GCP dan 8 ICP, serta survei kedalaman sungai menggunakan echosounder frekuensi 200 kHz. Alur pemrosesan meliputi penyelarasan citra, pembuatan dense cloud, konstruksi DSM/DTM, pembuatan ortofoto, dan integrasi data batimetri yang telah dikoreksi ke tinggi ortometrik menggunakan model geoid SRGI. Evaluasi ketelitian menunjukkan nilai CE90 sebesar 0,064 m dan LE90 sebesar 0,073 m, memenuhi standar ketelitian Kelas 1 untuk pemetaan skala 1:1.000. Ortofoto yang dihasilkan memiliki GSD 2 cm dan mampu merepresentasikan detail morfologi tikungan sungai dengan sangat baik. DEM topobatimetri yang terintegrasi menghasilkan model elevasi menyeluruh dari darat hingga dasar sungai, yang dapat dimanfaatkan untuk analisis pola aliran, identifikasi area erosi–deposisi, serta evaluasi perubahan bentuk meander Sungai Wonokromo. Hasil ini menunjukkan bahwa dataset yang dihasilkan sangat layak digunakan untuk analisis hidromorfologi dan perencanaan mitigasi banjir di kawasan tersebut.
