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

To provide adequate and quality air transportation facilities and infrastructure by developing and maintaining a sustainable air transport infrastructure, it is ?required attention to occupational safety and health risk factors. These factors need to be analyzed in order to achieve zero accidents in the implementation process. This study aims to identify OHS risk factors, determine the highest OHS risk factors and then prepare a Construction Safety Plan (RKK) based on the highest OHS risk factors in The Terminal Building Construction Of The New Mentawai Airport Development Project, to determine the control of these risks. Interviews, and questionnaires as well as the results of previous studies, were collected to determine the risk factors for OSH. The Analytical Hierarchy Process method was applied to determine the highest risk factor which was carried out by compiling the AHP questionnaire and inputting it in the Expert Choice application. The Construction Safety Plan is prepared after the AHP analysis, in which the required OHS costs are also known. There are 4 aspects of risk factors: Workers Aspect, Management Aspect, Equipment Aspect, and the Environment Aspect with 24 risk factors. The risk factor for worker burnout, which is part of the worker aspect and is carried out in structural work, is the highest. Furthermore, the Construction Safety Plan (RKK) is prepared based on the Regulation of the Minister of Public Works of the Republic of Indonesia Number 10 of 2021 concerning Guidelines for Construction Safety Management Systems with an OHS cost of this construction IDR 698,250,000.00. This study emphasizes the importance of paying attention to risk factors, namely the burnout condition of workers, which is rarely considered in the implementation of construction work.

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

In construction project management, achieving three main goals, namely cost, quality, and time, becomes the primary focus. This study aims to evaluate a road widening project in Mojokerto Regency with a target completion time of 150 days. To prevent delays and cost overruns, researchers adopted the Earned Value method as a tool to identify early warnings regarding project performance. This method integrates cost and time measurements through indicators such as Cost Variance (CV), Schedule Variance (SV), Cost Performance Index (CPI), Schedule Performance Index (SPI), Estimated at Completion (EAC), and Estimated Schedule at Completion (EAC). The analysis results show that the additional costs required (ETC) amounted to Rp 3,276,704,110.14, with an estimated additional time (ETS) up to the 12th week being 87 days. The project's cost change (EAC) reached Rp 3,961,767,811.01 from the contract cost, while the estimated project completion time (EAS) was 171 days. These findings indicate that the construction service provider has implemented an efficient execution method with consistent monitoring, ensuring the smooth progress of the project.

Abstract

The reconstruction of the Surabaya-Gempol Toll Road underscores the critical role of effective project management in large-scale infrastructure projects, particularly in ensuring time and cost efficiency. This study employs the Earned Value Method (EVM) to evaluate project performance through the analysis of Schedule Variance (SV) and Cost Variance (CV). These indicators provide a comprehensive assessment of the project's adherence to its planned schedule and budget. The findings reveal that the project faced initial schedule delays due to logistical and technical challenges, resulting in negative SV values during the early weeks. These delays were primarily caused by weather conditions, late material deliveries, and coordination issues among project stakeholders. However, corrective measures, including extended working hours, additional labor deployment, and optimized scheduling, successfully addressed these issues, leading to positive SV values towards the end of the project. The CV analysis highlighted consistent cost efficiency throughout the project. Positive CV values dominated the majority of the timeline, reflecting effective cost control and resource management. Despite minor cost deviations due to unanticipated repairs and equipment maintenance, the project demonstrated an ability to maintain overall financial performance within the budget framework. This study emphasizes the significance of data-driven decision-making and proactive variance management in achieving project goals. By leveraging SV and CV analyses, infrastructure projects can better anticipate potential issues, implement timely corrective actions, and improve overall performance. The results of this research offer valuable insights for managing similar large-scale projects, contributing to enhanced efficiency and sustainable development in Indonesia's infrastructure sector.
