In order to support Laga-Bauguia trade activities, the Ministry of Public Works (PU) is building a road network to the southern region. In its development, there is the development of the Laga-Bauguia Access Road which will be implemented from February 2023 to February 2025. This highway is one of the most important highways because it will connect the north coast area and cross the hills to the Matabian Mountains area which is visited by many tourists. local and foreign. This research aims to analyze the performance of the Laga - Bauguia Highway improvement project in terms of costs and analyze the estimated costs for the remaining work, as well as the cost of completing the Laga - Bauguia Highway improvement project. Every construction project requires control measures in terms of costs, where in carrying out control it is necessary to know in advance the ongoing project performance. One way to determine the cost performance of the project is the Earned Value method. This method can reveal whether the progress in implementing project work is commensurate with the use of part of the budget. By analyzing the concept of Earned Value, the relationship between what has actually been achieved physically and the amount of budget that has been spent can be seen. During the review period in the 8th month, a CPI value of 5.50 was obtained, which means that the actual costs incurred were less than the budget costs. In the 13th month, the CPI value was obtained at 5.50, which means the actual costs incurred were smaller than the budgeted costs.

Resources in the project were definitely limited so planning must be thorough and perfect. To achieve this goal, developers, contractors, and project owners create a project implementation schedule as well as control the implementation of the project itself. Scheduling determines when activities will be started, postponed and completed, so that resource control will be adjusted to the needed that had been determined. In project planning, scheduling was very important in projecting the needed of manpower, materials, and equipment. This study aims to assess project scheduling in general based on literature sources in the form of previous research (journals). The method used in this study was a literature study related to scheduling studies based on construction projects. Data were obtained from several library sources in the form of research journals for the last 5 years related to the research topic. The results showed that each method was complementary, such as LoB combined with CPM or PDM. In scheduling a construction project, a combination of methods needed to be applied to suit the desired construction project.

This study aims to identify critical tasks in the construction of a 4-floor building at Kadiri University using the Critical Path Method (CPM). The project is planned to be completed within 43 weeks, from October 2023 to August 2024, with a budget of IDR 20,551,534,000. Data collection involved direct site visits for primary data and secondary data from project documentation, including the Cost Budget Plan (RAB) and project schedule. Using Microsoft Project software, a project network was mapped, and CPM analysis was performed to identify the critical path. The analysis revealed that several tasks, such as site cleaning, demolition, temporary project fencing, heavy equipment work, geotechnical work, and various structural works from the 1st to the 5th floors, are on the critical path. These tasks have zero slack time, indicating that any delays will directly impact the overall project timeline. Identifying the critical path is crucial for project managers to prioritize resources and efforts on these tasks to ensure the project stays on schedule. This study underscores the significance of CPM in project management for timely completion and effective resource allocation, providing valuable insights for managing similar construction projects.

The lecture building is an important building which is the center of academic activities where educational activities are carried out. Currently, the construction of a four-story lecture building at Kadiri University is experiencing significant project delays with a deviation of 5.64% from the plan. Crash analysis can be carried out to speed up the duration of the project so that it can be completed on time with additional working hours. This research aims to determine crash time, crash costs, and cost slope for the application of overtime on the 4-story building construction project at Kadiri University. A quantitative and case study approach was used with data collected through observation, interviews, and analysis of project documents. Critical Path Method (CPM) analysis is carried out using Microsoft Project software to identify work that is on the critical path. Crashing is done by calculating crash time, crash cost, and cost slope. The research results show that applying 1 hour of overtime can speed up the project by 12 working days, with an additional cost of IDR 24,488,758. Cost slope analysis shows additional overtime costs of IDR 12,244,379. This research shows that the application of measurable overtime and crashing analysis can effectively overcome project delays in the context of building educational facilities.

In rapid construction developments, delays still occur frequently and have not been resolved, as experienced by the GX Office & Co Working Bali project. The project will be completed in 42 weeks, but in the 27th week, there is an indication of a delay of -4.31% from the initial plan. Earned Value Method (EVM) is a time and cost performance assessment method that can be used to develop strategies to minimize delays. This research aims to evaluate the time and cost performance of the GX Office & Co Working Bali project using the EVM method. A quantitative approach is used to collect and analyze project schedules, actual costs, and progress reports. EVM key indicators such as Planned Value (PV), Earned Value (EV), and Actual Cost (AC) are analyzed to determine Schedule Variance (SV), Cost Variance (CV), Schedule Performance Index (SPI), and Cost Performance Index (CPI). The results showed that the project experienced delays, especially from week 1 to week 14 and week 19 to week 27, with SPI values mostly below 1. However, the project showed increased efficiency in cost management with values CPI above one after week 14 to week 27, indicating that the actual costs incurred are lower than the value of the work completed. These findings highlight the need for corrective actions and more effective management strategies to address delays efficiently in terms of costs.

Infrastructure development plays a very important role as capital in efforts to stimulate increased economic productivity, both at the national and regional levels, as well as reducing unemployment, alleviating people from poverty and of course improving the standard of living of the community at large. Delays in completing a project are a problem that often arises and can have an impact on the entire work, especially with time delays resulting in increased costs which can be detrimental to many parties. This delay also occurred in the Kapas-Glendeng 8 bridge construction project, Bojonegoro Regency. In anticipation of these delays, it is necessary to accelerate time and costs. In this research the author uses the crashing method with the alternative of increasing working hours. The crashing method is a way of estimating cost variables to determine the maximum and most economical reduction in the duration of an activity that is still possible to reduce. The research results showed that the total time and cost of the project required after crashing was 174 calendar days with a cost under accelerated conditions of Rp. 2,555,189,555.98 with a difference of 6 calendar days from the normal duration of 180 calendar days and a fee under normal conditions of Rp. 2,548,581,990.63.
