Abstract

Toll roads play a crucial role in supporting national economic mobility and growth. Quality risks such as grain leakage, crocodile skin cracks, curls, grooves, removal of asphalt layers, and collapses frequently occur on the Tangerang-Merak Toll Road, specifically in the Balaraja-Cikupa section. This study aims to integrate the Failure Mode and Effect Analysis (FMEA) method with the ISO 9001:2015 standard to enhance risk management within the quality management system of toll road projects. It also evaluates the model’s effectiveness in reducing potential failures, improving quality, and aiding decision-making. The study focuses on selected clauses from the ISO 9001:2015 quality management system, including planning and controlling operations, product and service requirements, control of externally provisioned processes, and involvement of production and service providers. The Risk Priority Number (RPN) is used to analyze potential failure modes, measured by severity, occurrence, and detection. At the study site, the highest RPN value was 294, linked to an asphalt mixture that was insufficiently liquid. The failure modes most strongly related to quality degradation were cracks and deformations undetected during initial inspections (X2-9), with a correlation of 0.922 and a significance value of 0.000. The combined effect of all free variables (X1, X2, X3, X4) on the decrease in work quality at the site (Y) accounted for 70.7%. This integration of FMEA and ISO 9001:2015 provides a valuable framework for improving risk management and quality assurance in toll road projects.

Abstract

The Serayu Watershed is one of the critical watersheds in Central Java, particularly in the upstream. Aim: This study aims to assess the suitability of nature-based solutions (NBS) in flood risk reduction in the Serayu Watershed. Methodology and results: The collected data included the Serayu Watershed boundary and spatial datasets, consisting of a Digital Elevation Model (DEM), infiltration area map, soil erosion map, land use map, and slope map. The authors applied a spatial analysis method using the Geographic Information System (GIS) to integrate historical flood data, population density, topography, slope, geology, soil type, land use, water catchment area, water absorption area, groundwater basin, and erosion rate. The study found that within 10 years (2014-2023), 54 villages were exposed to flooding with a total area of ​​6,453.3043 ha or 8.010% of the area of ​​Purbalingga Regency. The analysis of land use changes from 2017 to 2022 shows a significant decrease in the area of ​​plantation forests-by 225,477.67 ha, from 323,979.26 ha to 98,501.58 ha. Conclusion, significance, and impact study: This study examines the regional characteristics and flood patterns of the Upper Serayu River in Central Java, Indonesia. Drawing on spatial analysis and hydrological data, the findings identified five NBS recommended for implementation: river floodplain restoration river and stream renaturation, building-related interventions, bioretention areas, and urban farming. These strategies align with local geormorphological conditions and offer sustainable approaches to flood mitigation. This study contributes to regional policy-making and supports the development of flood risk management in the Upper Serayu Watershed.

Abstract

The Moayat River in Kotamobagu, North Sulawesi, plays an important roleas a water source to meet the needs of the local community. However, water management in this area faces significant challenges due to seasonal discharge fluctuations, changes in land cover, and increasing water demand. This study aims to analyze the water availability of the Moayat River based on surface water conditions and current water demand assessments, future water demand projections, and water balance evaluations. The results show that current water availability is sufficient to meet domestic water needs. However, surface water conditions are influenced by climate change indicators, so that river discharge approaches the water demand threshold, thus creating a risk of water shortages,especially for irrigation. Over the past decade, forest cover in the catchment area has decreased, which has led to increased surface runoff and reduced water infiltration. Based on these findings, climate change in land cover greatly affects surface flow conditions so that an integrated management strategy is needed, including watershed rehabilitation, development of water storage infrastructure, and increasing water use efficiency, is essential to ensure the long-term sustainability of water supply from the Moayat River.

Abstract

Delays in project completion can lead to significant financial losses, reduced contractor performance, and decreased operational efficiency. This study analyzes the delay factors in the Proton Beam Building construction project at RSPAD Gatot Soebroto, identifying the primary causes and proposing targeted mitigation strategies. A mixed-method approach, combining qualitative interviews and quantitative surveys with key project stakeholders including planning consultants, construction management teams, contractors, and other involved parties is employed. The analysis utilizes the House of Risk (HOR) method to identify and prioritize delay agents and the House of Delay (HOD) method, supplemented by Forum Group Discussions for comprehensive insights. Keyresearch variables encompass human resources, materials, equipment, contract administration, project planning, field conditions, and stakeholder involvement. The study reveals that the primary causes of delays are inadequate planning, design changes, and a shortage of qualified human resources in construction management and planning consulting. The HOR methodology identifies the top three delay agents: Planning not in accordance with regulations (A8), Design changes (A6), and Lack of human resources (A4). To address these issues, the study proposes mitigation strategies, including the creation of a comprehensive checklist for regulatory compliance during planning, ensuring design alignment with applicable regulations, and developing contingency plans to addresspotential human resource shortages. These strategies aim to reduce the most significant delay risks, improve project efficiency, and enhance overall project compliance.

Abstract

Rainfall forecasting plays a crucial role in disaster risk management and water resources management in urban areas such as Asahan, North Sumatera. This research explores the application of ARIMA (AutoRegressive Integrated Moving Average) model as a forecasting method to predict rainfall in Asahan, North Sumatera. Historical rainfall data from relevant meteorological stations were collected and used as the basis for developing the forecasting model. The ARIMA method involves identification, estimation, and diagnostic steps. A series of statistical analyses were conducted to determine the degree of autoregression (p), the time series that need to be integrated (d), and the degree of moving average displacement (q). The resulting ARIMA model was then tested on test data to evaluate forecasting accuracy. At this station, the accuracy is 50%, which means that rainfall forecasting at this station when using ARIMA(1,1,1) is quite accurate.

Abstract

The increasing need for basic urban facilities and infrastructure, such as housing, can result in a reduction in green open land which can reduce the ability of water to infiltrate into the ground and increase surface runoff. Aria Rempoa Townhouse, a housing complex that is still in the development process, may have problems like these. Therefore, it is necessary to implement the zero delta runoff concept with ecodrainage technology such as retention pond and infiltration well. Research was carried out on the design flood at the outlet before the townhouse is built and after the townhouse is built if the zero delta runoff concept is applied with retention pond and infiltration wells. There are 3 scenarios, scenario 0 before the townhouse is built, scenario 1 after it is built without ecodrainage technology, scenario 2 after it is built with a retention pond, and scenario 3 after it is built with infiltration wells. The research results show that scenario 2 fulfills the concept of zero delta runoff with a pool area of 42 m2 with a depth 3.5 m and 2 outlet pipes with diameter 10 inches without doors discharge the design flood at the outlet of 0,281 m3/sec which is smaller than design flood at the outlet before the townhouse is built of 0.288 m3/second.

Abstract

This research aims to develop an optimal delivery model for precast elements in the Board Mill construction project in Pelalawan Regency, Riau, which includes 7,412 precast elements. Using an engineer-to-order manufacturing system and flowshop production, simulations were conducted to evaluate delivery variables and their impact on duration and cost. Data from the simulations were analyzed using linear regression to determine the most optimal delivery model, with the significance of independent variables tested using a P-value threshold of ≤ 0.15. The simulation and calculation results show that the most optimal delivery model for delivering precast column, beam, slab, and crane beam elements is a delivery model with a 12-hour work period or with overtime. The optimal delivery condition for column elements uses 3 cranes and 9 trailers; for beam and slab elements, it uses 3 cranes and 8 trailers; and for crane beam elements, it uses 3 cranes and 7 trailers.

Abstract

Building Information Modeling (BIM) is one of the technologies in the field of AEC (Architecture, Engineering and Construction) that is able to simulate all information in a development project into a 3D model. Research in this thesis was carried out to analyze the results of the implementation of Building Information Modelling (BIM) 5D in dock work (Quay Wall Structure) by paying attention  to clash detection at the pre-construction stage, with a case study of the Patimban Port Project Package 6. The focus of the research is the application of BIM 5D in identifying and resolving design clashes that can have an impact on the estimation of work volume and cost. The method used is qualitative and inductive analysis using Tekla Structure 2021 BIM software for 3D modeling and clash detection identification. The results of clash detection identification are grouped into three categories, namely large, medium, and small. The implementation of BIM 5D shows significant volume changes in some work items. The volume of the Deck Slab (Pier Head) and Front Wall decreased compared to the initial RAB, while the volume of the Deck Slab (In-Situ Concrete) increased. The cost comparison shows a savings of 7.06% of the total initial cost of RAB Quay Wall Structure, which is equivalent to IDR 10,502,919,303.55. The implementation of BIM 5D by conducting clash detection is quite effective in identifying and resolving design clashes, mitigating errors and revisions when entering the construction stage, and can increase project efficiency in better communication and coordination.

Abstract

Construction projects often face challenges in maintaining a balance between execution and planning, especially in terms of time and cost. Delays and cost overruns often hinder project efficiency, which has an impact on the satisfaction of the project owner. This study aims to evaluate the cost and time performance of the Purwodadi Market development project in North Bengkulu Regency using the Earned Value Management (EVM) approach. The EVM method was chosen because of its ability to provide a comprehensive picture of the achievement of project performance in terms of time and cost. Data is obtained from the project's weekly report and analyzed using indicators such as Actual Cost of Work Performed (ACWP), Budgeted Cost of Work Scheduled (BCWS), and Budgeted Cost of Work Performed (BCWP). The results show that in the 9th month, the project achieved faster progress than scheduled with a Schedule Performance Index (SPI) of 1.068 and a Cost Performance Index (CPI) of 1.012. This shows that the project is running more efficiently in terms of time and more cost-effective compared to the planned budget. However, there are several months before (the 5th to 8th month) that show delays and wasted costs. The conclusion of this study is that the EVM method is effective in evaluating project performance and allows for the identification of areas that need improvement. Thus, the application of EVM is recommended to improve the management efficiency of similar construction projects.

Abstract

The construction industry currently contributes 13% to the world's Gross Domestic Product (GDP), uses 36% of global energy and produces 39% of energy-related CO2 emissions. The application of Environment, Social, and Governance (ESG) principles is increasing in construction management to achieve sustainability. The construction sector brings diverse impacts on the environment, especially through significant construction waste. The relocation of the National Capital City (IKN) to East Kalimantan has the principles of smart city, forest city, and sponge city which carry the concept of sustainable construction. So this study will analyze the factors that influence the implementation of sustainable construction management on project waste management in IKN. The method used is a survey method with a quantitative method approach and the research variables used are based on the results of a literature review. So that from the results of the analysis it is concluded that the factors that influence sustainable construction management on waste management are Energy Efficiency, where the indicator that has the highest value is the use of energy-efficient plants, machinery and equipment. This is because the implementation of work at IKN cannot be separated from a development approach that prioritizes the use of wise, efficient resources and minimal environmental impact.
