Abstract

Housing construction is a recurring and sustainable job. So if the scheduling does not take into account the character of this work then the repetitive work unit will experience a delay (lag). So that it will result in the duration of the project. To overcome this, an uninterrupted scheduling method is needed from one unit to the next. The scheduling method that matches this type of repetitive work is the Line of Balance (LoB) because each activity / activity is described in a straight line and the speed of work can be changed according to needs. This is to avoid the occurrence of crashes / conflicts between activities. This method can also minimize the delay time as mentioned above. But this method cannot show dependency between critical activities and the other activities. For this reason, another method is needed in order to fill this gap. The suitable method is CPM through Microsoft Project. This combination of methods besides managing the time of project implementation also regulates human resources, namely by maximizing the allocation of human resources. Because in this multi-unit project the quantity of work is the main thing. From some analysis calculations, the results obtained that the addition of buffers with productivity speed smoothing, and the acceleration of the duration of the activity more effective to accelerate the implementation time of the project with a duration of 154 days.

Abstract

Architectural work in a construction project, generally is a non-structural work. However, the implementation can require a long time and a large cost weight. The implementation of finishing work in multi-purpose building construction project of Gresik Regency that was already running and had problems, that is a lot of workers but lack of work progress, so an increase of the cost from budget planned. Therefore it needs to doing research that for get the actual time of project implementation and get Estimate at Completion (EAC). The results is that the actual time of project implementation is not suitable with time of project planning. The project has been to late so there is a decrease in project performance. In the 1st week of project implementation on time, in the 2nd week until the 15th week the project has been to late (schedule overrun). So based on the time of implementation, the project has decreased performance. The total estimated cost can be seen from the Estimate at Completion (EAC) calculation, which is Rp.274,424,152.89.

Abstract

Road infrastructure plays a crucial role in supporting economic growth, particularly in agrarian and resource-rich regions. This research aims to conduct a comparative analysis of rigid and flexible pavement types in terms of cost efficiency and construction duration on the Sambeng–Kedewan road segment in Bojonegoro Regency. Utilizing the MDPJ 2017 method for flexible pavement design and Pd T-14-2003 for rigid pavement, this research employs a quantitative descriptive-comparative approach to analyze structural thickness, estimated construction costs, and implementation timelines for both 20- and 40-year design life spans. Primary data were collected through field surveys, including Dynamic Cone Penetrometer (DCP) tests for subgrade CBR values, while secondary data were sourced from government agencies and technical literature. Traffic load analysis was performed using ESA5 (Equivalent Standard Axle 5-ton) and JSKN (Number of Commercial Vehicle Axles) parameters, and cost efficiency was evaluated through RAB (Cost Budget Plan) and life cycle cost analysis (LCCA). Findings from various case studies and technical assessments indicate that although rigid pavement involves higher initial investment, it offers greater longevity and lower maintenance expenses in the long term. This research provides crucial insights for local governments in determining the most efficient pavement type under limited budgets and strict construction timeframes. The results are expected to serve as a reference for future infrastructure planning in similar rural and agricultural regions.

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

An alternative solution to the availability of inadequate rain data as hydrological data input is with the help of Global Precipitation Measurement (GPM) satellite rainfall data using remote sensing technology (satellite). The purpose of this study was to find correlations and corrections of data and validate GPM satellite data with rainfall data at rain stations and observation data in the Jelai watershed. The corrected GP M rain data validation results in Nash-Sutcliffe Efficiency (NSE), Root Mean Squared Error (RMSE), Correlation Coefficient (R), and Relative Error (KR). The validation results resulted in NSE values of 0.33, RMSE 48.54, Correlation Coefficient (R) of 0.75, and Relative Error of 0.19 for 2019 and yielded NSE values of -0.14, RMSE 100.24, Correlation Coefficient (R) of -0.36, and Relative Error of 0.23 for 2020. The overall analysis shows that GPM data can be used as an alternative to rain data if in a watershed there is a small number of rain posts that do not meet the WMO criteria. As a suggestion for further research, it is necessary to calibrate and validate by distinguishing between rain data in wet years and dry years

Abstract

The development of physical facilities in Indonesia is increasing rapidly along with the promotion of modernization. In the implementation of a project it is very rare to find a project that goes exactly as planned. Generally, they experience delays from what was planned, both in terms of time and progress of work, but there are also projects that experience acceleration from the initial schedule planned. The research objectives were to determine time and cost performance, and to determine cost estimates and final project completion time for the Well Pad stockpiling and compaction project in the Rokan Riau Oil and Gas Block environment. The method used in this study is the Earned Value method which combines the elements of cost and time as well as the physical performance of the work. The data obtained from the project includes the project time schedule, budget plan (RAB), project weekly reports and actual costs, then an analysis of costs, schedules, variances and performance indexes is carried out by explaining the problems that arise during the research. Based on the results of the analysis and discussion, the calculation of the CPI value is> 1 from the 1st week to the 16th week. This means that from the 1st week to the 16th week, the project cost is more economical. The EAS calculation for the 16th week estimates the project completion time is 116 days or 16 weeks. This means that the project is experiencing a delay from the planned schedule. At the end of the review period, an estimated final project cost of Rp. 4,022,024,000.00. And the estimated time for project completion is 116 days, which means the project will be completed in a longer time than planned, which is 211 days.
