Abstract

This research presents a comparative analysis of the cost and construction time between flexible and rigid pavement structures on the Siwalanpanji-Kemiri road section in Sidoarjo Regency, East Java, Indonesia. The area is undergoing a functional shift from rural to industrial, necessitating durable infrastructure to accommodate increasing heavy vehicle traffic. Using the 2024 Indonesian Pavement Design Manual (MDPJ), the research evaluates the technical and economic viability of both pavement types over 20-year and 40-year service lives. Key parameters include Average Daily Traffic (ADT) projections, Cumulative Equivalent Single Axle Load (CESAL), and subgrade strength derived from Dynamic Cone Penetrometer (DCP) tests. These inputs inform pavement thickness designs and cost estimates based on local unit prices (HSPK). Findings reveal that flexible pavement offers faster construction (9 days vs. 39–49 days for rigid) but incurs 38% higher long-term costs due to frequent maintenance. Rigid pavement, despite longer initial construction time, proves more economical over 40 years, with lower maintenance needs and superior durability under heavy loads. Cost analysis shows rigid pavement saves up to IDR 3.5 billion compared to flexible alternatives over four decades. The study also highlights the sustainability benefits of reusing existing materials, aligning with environmental goals. These results provide actionable insights for the Sidoarjo Public Works Agency, emphasizing rigid pavement as the optimal choice for industrializing corridors. The research underscores the importance of life-cycle cost analysis and context-specific design in infrastructure planning, offering a model for similar regions facing rapid urbanization and traffic growth.

Abstract

Mojokerto is a region in East Java with strategic geographical and economic significance, serving as a key area for regional connectivity and growth. However, the Bendung-Bantengan road section has experienced considerable damage due to inadequate retaining walls, leading to road subsidence, cracks, and increased maintenance costs. These challenges necessitate effective soil stabilization measures to ensure the safety and functionality of the infrastructure. This study explores the application of Value Engineering (VE) to optimize the planning and construction of retaining walls in the region. Utilizing secondary data from topographic surveys and triaxial soil tests, this research evaluates three design alternatives to identify the most efficient solution. The analysis revealed that Alternative 1 demonstrated the highest cost efficiency, achieving a reduction in construction expenses by IDR 284,244,698.00 through the optimization of structural dimensions and material usage. In addition to cost savings, the implementation of VE also contributed to a shortened project timeline, reducing the completion period to 121 days from the originally planned 180 days. The design maintained its quality and structural stability, effectively resisting lateral soil pressure while mitigating erosion risks. This study underscores the significance of incorporating VE during the planning stages of infrastructure projects. By balancing cost efficiency, quality, and sustainability, VE enhances project value and ensures long-term resilience. The findings provide a strategic framework for future infrastructure projects, promoting sustainable and economically viable solutions for regions with challenging geotechnical conditions. VE’s integration into construction practices highlights its transformative potential in achieving efficient and durable infrastructure development.

Abstract

Evaluation of the final project cost and time estimates is essential to measure whether the project can be completed in accordance with the previously established budget and schedule. The calculation of the final cost and time estimates for the rehabilitation project of the Segiri Sports Hall Building in Samarinda City uses the Earned Value Method (EVM). The evaluation is performed by calculating the Estimate At Complete (EAC) for cost projection and the Estimate At Schedule (EAS) for the project completion time estimate. The analysis results show that the EAC experienced fluctuations, starting from Rp 44,648,760,330.58 in the first week of July and increasing to Rp 52,630,845,855.14 in the 15th week of November. This change was influenced by the increase in the Actual Cost of Work Performed (ACWP), which reached Rp 31,173,250,000.00 in the 15th week, as well as a decrease in the Estimate To Complete (ETC), reflecting cost adjustments. Although the EAC showed an upward trend from July to October, there was a decrease in November, indicating an improvement in project cost management. In terms of time, the EAS shows that the project was running ahead of schedule from the first to the third week, with EAS values ranging between 16.57 and 16.41. However, starting from the 4th to the 6th week, the EAS increased significantly, reaching 28.80 in the 6th week, reflecting a delay. Although there was a decrease in the EAS in the 14th and 15th weeks, the project still showed a significant delay compared to the planned schedule. These findings emphasize the importance of further evaluation in time management and resource allocation to minimize delays and ensure the project is completed on target.

Abstract

The procurement of goods and services was previously conducted manually or conventionally. Presidential Regulation No. 54 of 2010, which replaced Presidential Decree No. 80 of 2003, formally contained the objective of e-procurement in the procurement of government goods/services for the first time. Neither the committee nor the providers of goods/services readily accepted the newly implemented system. The success of the e-procurement program is highly determined by the human factor. User readiness to accept the technology is the key to successful implementation, because their response will determine whether this technology succeeds or fails. This study uses mixed methods and aims to obtain empirical evidence about the influence of human resource competence, infrastructure, and supervision factors in the implementation of the e-Procurement system, as well as to provide strategic recommendations for improving the implementation of the e-Procurement system in Ngada Regency. The research sample consisted of 39 employees of the Goods and Services Procurement Section of Ngada Regency, selected using the saturated sampling technique within the nonprobability sampling method. Data was collected through questionnaire surveys and interviews, then analyzed using Smart Partial Least Square 3.2. The results of this study revealed that human resource competence, infrastructure, and supervision have a significant influence on the implementation of the e-Procurement system in Ngada Regency. Improvement in these three factors can enhance the success of the e-Procurement system implementation. Some recommended strategies to improve the implementation of the e-Procurement system are to conduct education and training, provide internet networks and backup servers through the Department of Information and Communication, carry out socialization to involve the public in monitoring, increase evaluation transparency by adding an evaluation column on the Electronic Procurement Institution (LPSE) website, conduct routine audits, and issue regulations regarding the implementation of e-audit in the process of procuring goods/services.

Abstract

As one of the largest cities in Indonesia, the City of Surabaya has an obligation to provide excellent health services for its residents. It goes without saying that Surabaya City Government is required to provide a General Hospital that can receive referrals from the government-owned Community Health Centers. For this reason, the Surabaya City Government built the East Surabaya Hospital which is located in Rungkut Sub-District. East Surabaya Hospital is a strategic project that requires investment feasibility analysis. The East Surabaya Hospital investment feasibility analysis was done by applying the Net Present Value (NPV), Internal Rate of Return (IRR), Payback Period (PP) and Benefit Cost Ratio (BCR) parameters. After the feasibility analysis results were obtained, a sensitivity analysis was done on changes in management costs and the amount of health service levy rates for each Fees alternative. Based on the results of the investment feasibility analysis of 4 (four) Fees alternatives, there are 2 alternatives that can be concluded as worthy investments, which are alternative 1 and alternative 3. Meanwhile, alternative 2 and alternative 4 are not feasible since the NPV parameter shows negative values and the IRR value is lower than the MARR value. However, based on sensitivity analysis, alternatives 2 and 4 can be feasible if alternative 2’s service rate is increased by 13.2%, and alternative 4’s service rate is increased by 2.3%. The opposite applies in alternative 1 where the investment might become unfeasible if the service rate is reduced by more than 5.4% and alternative 3 might become unfeasible if the service rate is reduced by more than 2.5%.
