Abstract

Project delays in construction development have a major impact, especially on costs. Projects that experience delays in implementation will require large costs. One of the delay factors is caused by material selection, especially for wall materials. Precast AAC Panel wall and sandwich panel walls are current wall material innovations, but both differ in material composition, implementation method, and price. This research aims to analyze the effectiveness of the two types of walls in terms of cost and time. The research will use objects from the 24-story Sudimaran Forestwalk apartment development in South Tangerang. The research method uses quantitative methods by making a cost budget plan obtained from data on work volume, productivity, and unit price of work. Next, analyze the duration of work from productivity data and work volume. The analysis results for the budget for work costs using precast AAC panel materials cost IDR 11,640,163,103, while sandwich panel walls are IDR 16,223,117,608. For comparison of implementation time, precast AAC panel walls are faster, with a work duration of 623 days, and sandwich panel walls 784 days. From these price results, AAC panel walls are 23% cheaper than sandwich panel walls. Due to the low strength, the sandwich panel walls are sometimes damaged during construction, resulting in longer construction times. The analysis results show that precast AAC panel walls are more recommended as the choice of wall type in terms of cost and implementation time.

Abstract

Oil tank buildings are designed to be earthquake-resistant throughout their lifetime. The foundation of the 3000 bbl petroleum storage tank in Penukal Abab Lematang Ilir (PALI) Regency has been designed using previous seismic standards. This encourages the importance of evaluating foundation resilience against the latest standards because the latest standards show an increase in the Peak Ground Acceleration value. This research aims to determine the Safety Factor (FK) and settlement of the existing foundation of a 3000 bbl petroleum storage tank at the Collecting Station in PALI Regency using earthquake parameters in 2022. A quantitative approach was carried out using finite element and analytical analysis. Steel tank structure design, soil investigation, loads, earthquake parameters, and existing foundation design are used. FK and settlement results will be evaluated based on API 650 and SNI 8604:2017 requirements. The analytical and finite element research results show that the FK value meets the requirements. However, the FK value obtained tends to be too large compared to the requirements. Therefore, it is recommended to design a foundation size smaller than the existing foundation as an efficiency measure. Apart from that, the settlement results at the end of the service life (50th year) show that it is still within the settlement limit permitted by API 650. The research results have confirmed that the existing foundation can withstand earthquakes based on earthquake parameters in 2022. So, these results can be used to develop tank foundation designs for earthquake-safe oil storage in similar locations.

Abstract

In the implementation of housing development, the problem of late payment delays is a common issue encountered in commercial and subsidized housing projects during construction. These delays impact the timely completion and lead to disputes among the involved parties, which include owners, contractors, and subcontractors. This study aims to analyze the primary factors contributing to late payment in construction projects, specifically in commercial and subsidized housing. The analysis is conducted from the perspective of the owner, contractors, and subcontractors. The study involves six owner respondents, six contractor respondents, and four subcontractor respondents. The survey results were analyzed using the Analytical Hierarchy Process (AHP) to assess the significance of various factors influencing payment delays in both housing schemes. The analysis results indicate that financial issues with the owner's company are crucial factors from the owner's perspective in causing payment delays in both commercial and subsidized housing projects. A major challenge faced by contractors is the lack of capital availability, which can lead to delays that affect all involved parties. Meanwhile, discrepancies between job specifications not following the contract from the subcontractor's viewpoint highlight the importance of clear communication and rigorousness. All parties involved in housing projects need to improve financial management, enhance capital procurement, and tighten the supervision of contract implementation. By identifying key factors, adopting best practices can help mitigate the risk of payment delays and improve efficiency in future housing project implementations, whether commercial or subsidized.

Abstract

Construction design changes are a challenge that requires quick adjustments in project documents, especially in the Bill of Quantity (BoQ). These adjustments reflect major changes in costs and material requirements. The use of digital technology is key to facilitating this process, enabling faster and more accurate revisions. This research aims to compare volume calculations using Revit and manual volume calculations resulting from design changes in the YOGYA Kota Baru Parahyangan Development Project. In the process, the volume of material required for various construction elements is calculated manually and with the help of digital technology. The results of these two methods were then compared to determine significant differences and evaluate each method's efficiency and accuracy. This results show that the volume difference in profile steel profiles is +47.78%; concrete +21.83%; piles +12.06%; and reinforcement +2.00%. These findings show that Revit provides more accurate and detailed results than manual calculations, which are often prone to human error. Using Revit can speed up the design adjustment process, reduce costs and project completion time. This research contributes by providing empirical evidence of the benefits of digital technology in construction and practical guidance for professionals in choosing the right calculation method.

Abstract

The Ciceri intersection is in a densely populated urban area characterized by heavy traffic, particularly motorbikes. This is due to the nearby educational institutions, shops, offices, and a shopping center. The intersection faces numerous traffic conflicts, including crowded vehicle queues, irregular queuing by motorbikes, and improper lane usage by two- and four-wheeled vehicles. The phase setting of traffic signaling devices (APILL) at the Ciceri intersection has been implemented but has not solved the problem. This research aims to analyze the use of RHK to improve the performance of the Ciceri intersection using the Vissim model. The method is to test or simulate various RHK models at the research location. The results obtained can be applied to the RHK at two intersection legs, namely east and west, with a box-type RHK measuring 8m long and 2 x 3.5m wide, increasing the level of Service (LOS) from E to F. The results show a reduction in queues of 5.64 m and delays of 1.52 seconds on the north leg, as well as a reduction in queues of 7.85 m and a delay of 13.48 seconds on the south leg. These results show that RHK can effectively improve the performance of intersections with high traffic volumes without the need to increase physical road capacity.

Abstract

Economic development in Bojonegoro is growing rapidly due to massive building construction. However, delays in building construction projects in Bojonegoro are a significant issue because they have a negative impact on costs, efficiency, and local economic stability. Identifying building project delay factors, especially in Bojonegoro, is important because project delay factors may differ from other areas. This research aims to identify and analyze factors influencing building project delays in Bojonegoro. The factors observed include materials, labor, equipment, finance, environment, and design changes. The research uses a quantitative approach and a questionnaire survey method, which has undergone instrument testing on 35 respondents involved in building construction projects in Bojonegoro. The data was tested on classical assumptions and analyzed using hypothesis testing (F and T tests) to determine the effect of each variable on project delays and ranking based on the coefficient values. The research results show that all variables studied significantly influence project delays, with labor as the most dominant factor, followed by environment and finance. Changes in design, equipment, and materials also contribute, although with a smaller impact. This research provides a strong empirical basis for project managers and related parties to develop more effective strategies for managing construction projects, reducing delays, and increasing project efficiency in Bojonegoro.

Abstract

Waste is a problem that cannot be ignored because it is always generated in all aspects of life. The Climate Resilient and Inclusive Cities CRIC Waste Assessment Tool helps in analyzing the current situation in the city and provides important and practical recommendations from both technical aspects, governance, and social issues. The research aims to evaluate urban waste management using the Climate Resilient and Inclusive Cities (CRIC) Waste Assessment Tool based on management technology in Palembang City. A quantitative strategy was used in this research, along with a descriptive and verification research method. Secondary data is taken from the national waste management information system and other literature to fill in the CRIC Waste Assessment Tool application. Data analysis using CRIC Tool covers waste management, governance, economy and knowledge of citizens, GHG emissions. The results of measuring waste management performance with CRIC show that waste management in the city is still low, most of the waste is disposed of uncontrollably, resulting in SLCPs. Waste banks and TPS3R are still lacking. Achievement of waste management to reduce greenhouse gas emissions has only reached 50% of the recommended target. Proper waste handling is still lacking, such as reduced dumping, open burning, and better composting practices. This will support modifications in waste handling from the community, which can support waste management technology development.

Abstract

Road pavement quality is a critical factor in supporting a country's mobility and economy. Around 40% of the road length in Indonesia suffers damage, including permanent deformation and early cracking. To overcome road damage, it is important to know the pavement quality parameters such as Voids in Mineral Aggregate (VMA), Voids in Mix (VIM), and Voids Filled with Bitumen (VFB), along with the factors that influence them, such as material characteristics. This study aims to determine the effect of the fine and coarse aggregate ratio on volumetric parameters in asphalt mixtures, including VIM, VMA, and VFB. The experimental method was carried out on four samples. Aggregate characteristic tests were carried out, including gradation tests. Volumetric tests were carried out on each sample with asphalt content of 4%, 4.5%, and 5%. The research results show that the smaller fine-to-coarse aggregate ratio would increase the VMA and VIM values and decrease the VFB value. Aggregate ratio significantly affects volumetric parameters, which shows the importance of selecting aggregate with the right size distribution and determining the right ratio to achieve optimal pavement performance. The results of this study can be used as a practical guide for optimizing asphalt mix design with better quality and durability.

Abstract

Building A at the Surabaya UPT Vertical Hospital is an example of using limited land to meet space needs. However, the oval shaped geometry of the building causes the frame structure to be different from usual. This changes in geometry has an impact on the occurences lateral and mass irregularities in the building structure. This study aims to analyze the stability and performance of oval structures by considering the influence of earthquake loads. The capacity level of structure is evaluated using the Performance Based Design method. This method involves conducting a Pushover Analysis by applying a predefined lateral dynamic load to the structure and gradually  increasing it until the structure reaches its maximum capacity, ultimately leading to the structural failure. The results of this research obtained a ductility value of 1.21 for the X axis and 1.46 for the Y axis, this value makes the structure classified as partially ductile and not fully ductile. The performance level of the structure on the longitudinal axis (X) is 0.002 and on the transverse axis (Y) is 0.0019, so the structure is classified as SP-1 Immediate Occupancy, which means that the damage caused is not dangerous even if an earthquake occurs. The results of this research can be used as a guide in planning and evaluating oval or other irregular building structures, especially for vital buildings in areas with high earthquake risk.

Abstract

The coal mining activities conducted by PT Pamapersada Nusantara in the Pit Tutupan, South Kalimantan, employ an open pit mining system. This method creates exposed working surfaces that can accumulate rainwater runoff. This study aims to design a drainage system to manage water control in the western high wall area of RL 16, considering the impact of mining progression. The planning involves calculations for scheduled rainfall, rainfall intensity, estimated water discharge, open channel dimensions, culvert, and the number of pumps required to manage water in the pit sump. Using the Log Pearson III distribution, planned rainfall is determined at 101.499 mm for a 2-year return period and 134.782 mm for a 5-year return period. The rain catchment area at the research site in Sump RL 16 HW Barat is 84.83 hectares. The proposed trapezoidal channel design accommodates varying water discharges: 4.47 m³/s, 5.04 m³/s, 8.75 m³/s, 7.87 m³/s, 7.20 m³/s, and 3.77 m³/s for tertiary, secondary, and primary channels. The sump is designed to store two days’ worth of rainfall, with a capacity of 186,516 m³. Excess water is pumped to an external drainage system and settling pond using a Direct Multistage Pump system. The primary pump planned is the Multiflo 420 EX, complemented by a Warman 8/6 AH booster pump. Both pumps utilize TYCO PE100 HDPE pipes, ensuring efficient water transfer to the drainage system and settling pond, optimizing mine water management. The research results can be a reference for planning mine drainage systems with similar characteristics.
