Abstract

The GX Office & Co Working Bali construction project faced significant delays in the 27th week with a deviation of -4.31%, which could result in increased costs and delays in completion. So, an effective solution is needed to overcome project delays and ensure that the project is completed on time and within budget. This research aims to examine the application of the Earned Value Method (EVM) in evaluating the performance of the GX Office & Co Working Bali project by calculating the Estimated Temporary Schedule (ETS), Estimated All Schedule (EAS), Estimate Temporary Cost (ETC) and Estimate All Completion (EAC). The research uses descriptive quantitative methods by collecting data from weekly project progress reports, actual costs, and planned values. Data analysis was carried out by calculating Planned Value (PV), Earned Value (EV), Actual Cost (AC), Cost Performance Index (CPI), Schedule Performance Index (SPI), ETS, EAS, ETC, and EAC. The research results show an ETS value of 114 days with an EAS of 303 days. So, there is an additional time of 9 days from the planned schedule. ETC results amounted to IDR 3,723,631,710.12, with EAC amounting to IDR 7,699,818,710.12. So, the cost of completing the project is lower than planned, with a difference of IDR 2,545,727,760.88. The results of this research contribute to the project management literature by showing the effectiveness of EVM in identifying deviations and the basis for making strategic policies needed so that projects can be completed on time according to plan.

Abstract

The growth of commercial areas in urban areas, especially shopping centers, has contributed significantly to the increase in traffic volume. This study aims to analyze the influence of Royal Plaza visitor activities on traffic volume and degree of saturation on the Jalan Ahmad Yani network, Jalan Ketintang, and the Ahmad Yani-Ketintang intersection in Surabaya City. The method used refers to the Indonesian Road Capacity Guidelines (PKJI) 2023, with primary data collection through a traffic volume survey for four days in three time periods (day, evening, night), then analyzed to obtain capacity values, actual volume, and degree of saturation (DS) on each road segment. The results of the analysis show that the highest traffic volume was recorded at 5444.70 SMP/hour on Jalan Ahmad Yani, with a road capacity of 5115.64 SMP/hour, resulting in a degree of saturation (DS) value of 1.06. This value indicates that the level of road service is in category F, which reflects very saturated traffic conditions and congestion. Meanwhile, the Ahmad Yani–Ketintang intersection shows DS ranging from 0.85 to 1.19, depending on peak times. This finding confirms that the presence of Royal Plaza places a significant traffic burden on the surrounding road network, and a traffic management strategy is needed to mitigate the impact and improve road service performance.

Abstract

This study aims to obtain the form of project work network in the Probolinggo City Hospital Development Project, to determine the effect of accelerating the duration of Probolinggo City Hospital Development work on network planning and to find out the amount of costs incurred before and after the acceleration of the duration of project work. The method used is the acceleration method with modification of the scheduling of the CPM model. CPM method planning is a recommendation in choosing from many existing methods, because there is a calculation of the earliest time the project starts, the last time the project starts as well as the earliest time to finish and the last time to finish so that it can be known the time lag of all activities. Data Used are primary and secondary data related to the sequence and relationship of activities, implementation time and cost budget plan (RAB). In this thesis, the author takes scheduling data from the Probolinggo City Hospital Development Project which will be used as the basis for writing this thesis in conducting CPM analysis and accelerating the duration of work with additional overtime working hours and calculating the total cost of the acceleration to be used as comparison material in the writing results. Based on the analysis that has been carried out using the Microsoft Project 2016 application, the normal duration of structural work is 81 working days and has 18 critical units of 31 work items. After the acceleration was carried out, there was a decrease in the duration of the work of the structure to 74 working days. The difference in duration decrease was 7 days or 9.45%. The total initial cost with the normal duration for structural work is IDR 28,563,131,560, while after acceleration, the project cost for structural work becomes IDR 28,635,083,793

Abstract

The need for housing continues to increase as the number of inhabitants increases. Housing development as one of the efforts to meet the needs of the community for residential houses. The Andalusian Griya Giri housing estate in Gresik Regency was built with a type. However, with the vast area in Gresik Regency and the fierce competition of housing developers who offer housing in a higher segment and at prices that do not differ much, it can be concluded that this housing is a waste of costs in development. Therefore, a way is needed to overcome this problem, namely by applying Value Engineering. This study aims to analyze the optimization of the calculation of the cost budget plan without reducing the quality and function of the building with the Value Engineering method. The analysis technique in Value Engineering of this study uses a comparative method with cost analysis. This method compares the profit price of the landcape design before it is redesigned with the design that has been redesigned, namely changing the house plan, appearance and number of house compositions / site plans so that maximum profit is obtained. This analysis uses the stages of the Value Engineering plan, namely the information stage, stage, creative, analysis stage, recommendation stage and presentation stage. Based on the results of the Value Engineering analysis at the Griya Giri Andalusian Housing Project in Gresik district, the most profitable design alternative was to use Design C with the change of type 38/72 housing units to 36 units. The profit price after redesigning from the original design, the production price of the type 38 house is Rp. 122.2 40. 00,000 becomes Rp. 9 0.728.514. The amount of profit increased generated after the redesign of the original design and the change in the number of house compositions / site plans was carried out amounting to Rp 7,864.960. 000 becomes Rp. 9,981,773,496.

Abstract

The Situbondo – Ketapang – Banyuwangi Road and Bridge Preservation Project experienced changes in the work area, requiring additional design. Asphalt overlay work was halted awaiting the test results of Asphalt Modiv PG – 70 from the Pusjatan Road Material Laboratory in Bandung, resulting in a delay in week 40 by -0.813%. Specifically, AC - WC and AC - BC asphalt work was delayed, significantly impacting the overall project performance. Cost and time analysis are crucial to address this issue. The Earned Value Management (EVM) method is used to evaluate project duration and costs. The Cost Performance Index (CPI) indicates good cost performance (>1), but the Schedule Performance Index (SPI) indicates schedule delays (0.983 < 1). The final project cost is estimated at Rp 112,439,121,070.91, with a completion time of 453 days, three days longer than planned. Effective strategies are needed in time control and design adjustments to complete the project according to expected standards.

Abstract

Effective project management is the key to success in constructing the boarding school of SMA Muhammadiyah 3 Tulangan. Despite facing various challenges such as design changes, inclement weather, and limited workforce resources, the project is monitored using the Earned Value Method. Analysis of BCWS, BCWP, ACWP, SV, CV, SPI, and CPI indicates initial delays and budget overruns, but significant improvement later on. Despite weekly cost variations, the project remains financially manageable. The conclusion shows time delays but cost performance is under control. This underscores the importance of project performance evaluation and the use of the Earned Value Method in construction projects.
