Abstract

Batam City with existing drainage issues is a major hindrance to its performance. Road construction is always related to drainage funcitionality. The existing condition, with heavily piled-up sediments, causes a significant issue for Batam, Nagoya, and Batam Kota sub–district. Sediment accumulation in the drainage base depth causes a reduction in drainage volume, resulting in backflow and disturbance of water flow dynamics. This slowly erupts to the surface and cause flooding in roadways. Flooding roadways cause traffic congestion, erosion of the road structure, and accumulation of sediments due to the intensity of rainfall. Which resulting damages to drainage system. By installing sediment traps on manholes and lower base drainage, it can help reduce the buildup of sediments on the drainage base. Which will reduce flood risk and allow water to flow smoothly without resulting in backflow.

Abstract

This study evaluates the drainage capacity of Ocarina Road, Batam City. Hydrological analysis using three probability distributions shows that the Generalized Extreme Value (GEV) distribution is the most appropriate based on the Kolmogorov–Smirnov test. The 25-year return period design flow calculated using the Rational Method is 1.546 m³/s, while the capacity of the existing U-ditch channel is only 1.17 m³/s. Validation using HEC-RAS shows water levels approaching the channel edges, confirming that the hydraulic capacity is inadequate. The channel also does not meet the 0.25 m safety height standard for discharge of 1.5–5.0 m³/sec according to KP-04 of the Directorate General of Water Resources. These results indicate that the channel capacity is inadequate, requiring an increase in channel dimensions or the addition of supporting infrastructure to reduce the risk of flooding.

Abstract

This study utilizes FAARFIELD software to calculate the necessary overlay thickness for the runway pavement at Hang Nadim International Airport. The evaluation relies on primary data, including field assessments such as Pavement Condition Index (PCI) analysis and Dynamic Cone Penetration (DCP) testing, to estimate subgrade bearing capacity. Secondary data is sourced from the Airport Pavement Management System (APMS), which provides historical pavement conditions, maintenance records, and aircraft traffic statistics. The results show that for the runway section from STA 0+000 to 4+025, with a subgrade CBR of 8%, the required overlay thickness is 55 mm (5.5 cm) of Hot Mix Asphalt (HMA). These findings incorporate projections of aircraft traffic growth over 20 years, ensuring the pavement's structural integrity despite increasing loads. The study also emphasizes the need for future research to refine methodologies for determining subgrade bearing capacity. While historical CBR data is available, updating field data will offer a more accurate reflection of current subgrade conditions. Moreover, DCP testing on the runway side may not accurately reflect conditions at the runway center, suggesting the use of core drilling to verify subgrade conditions at critical points. Core drilling can provide more precise depth measurements for reconstruction based on observed damage.

Abstract

Infrastructure projects frequently face challenges such as cost overruns and schedule delays, which are generally caused by suboptimal risk management practices. This condition highlights the importance of early and integrated planning, sustainable stakeholder collaboration, and evidence-based decision-making. Accordingly, this study aims to identify and analyze the key risk factors that influence the optimization of risk management strategies in infrastructure projects. This study employs a quantitative approach, with data collected through an online questionnaire distributed to 31 infrastructure professionals in Batam City, Indonesia. The respondents consist of project managers, engineers, consultants, and contractors selected using purposive sampling to ensure the relevance of practical experience. Although the sample size is limited, it is considered adequate for an exploratory study focused on the local context. The results indicate that internal risks, particularly inadequate planning and ineffective work management, have a more dominant impact than external risks such as climatic conditions. Other significant factors include financial instability, design changes, and client-driven variations. Statistical analysis using SPSS reveals a significant positive correlation between proactive stakeholder involvement and the effectiveness of risk response strategies. Furthermore, the use of historical data and formal risk documentation contributes to improved mitigation effectiveness. This study concludes that optimizing risk management in infrastructure projects requires an adaptive and evidence-based approach to enhance project resilience and minimize delays and cost overruns.

Abstract

The planned villa development in the hilly area of Cisarua, Bogor, requires a comprehensive geotechnical study to ensure the safety and reliability of the building foundations. This study aims to identify soil layer characteristics, determine soil consistency, and evaluate the allowable bearing capacity of shallow and deep foundations based on Cone Penetration Test (CPT) results at three investigation points. Primary data consist of cone resistance (qc) and total sleeve friction (Tf) measured at 20 cm depth intervals, which are then interpreted to obtain the stratigraphic soil profile, in-situ soil classification using qc and friction ratio (fr), as well as the calculation of allowable bearing capacity using the L. Herminier approach for shallow foundations and the Meyerhof method for deep foundations. The results indicate that soft to firm soil layers are found at shallow depths, while hard soil layers with qc values of about 250 kg/cm² occur at depths of 24–25 m, which are suitable as the main bearing layer for deep foundations. The allowable bearing capacity of shallow foundations at depths of 1.0–2.0 m ranges from approximately 1.9 to 12.0 ton/m², making them suitable only for light structures with careful settlement control, whereas for heavier structures, pile foundations extending to the hard layer are recommended, supported by static load tests and, if necessary, additional deep boring and SPT investigations.​

Abstract

Concrete compressive strength is a fundamental parameter for evaluating the performance of concrete structures. Although destructive testing using a Compression Testing Machine (CTM) is considered the most accurate method, its limited applicability to existing structures has led to the use of non-destructive methods, such as the rebound hammer test. However, rebound hammer results often deviate from CTM measurements, raising concerns regarding their reliability. This study examines the impact of rebound hammer test point location on the variability and accuracy of estimated concrete compressive strength, and assesses its agreement with destructive test results. A quantitative laboratory experimental program was conducted using concrete with a target strength of 15 MPa. Five cylindrical and five cubic specimens were tested at 28 days. Rebound hammer tests were performed on top, bottom, and side surfaces in accordance with ASTM C805, followed by destructive compressive strength testing using CTM based on ASTM C39. The results show that test point location systematically influences rebound hammer outcomes. Bottom test points produce the highest estimated strengths and the largest deviations from CTM results, whereas top test points yield the closest agreement with actual compressive strength. The findings confirm that rebound hammer accuracy is position-dependent and should be explicitly considered in concrete strength evaluation.
