Abstract

In a construction project, preparation work typically includes tasks related to setting up work facilities, conducting field investigations, obtaining permits, and non-structural activities. The Jakarta Sewerage Development Project Zone 1, Package 2, which involves the construction of sewers in Area 1-1, is currently in the preparation phase and is experiencing challenges due to a complex permit process. This has led to minimal progress as the initial project planning did not consider the time needed to secure the necessary permits for implementation. The author is therefore evaluating the project timeline to gauge performance during the preparation phase before actual construction begins. This study utilizes the Critical Path Method (CPM) scheduling technique in Microsoft Project to pinpoint critical activities. Upon analysis, it was found that the budget plan for Package 2 of the Jakarta Sewerage Development Project (Zone 1) was detailed and included various work descriptions, with a total budget of IDR 862,292,086,196. However, delays have occurred, resulting in a 17-day setback in the project schedule, necessitating work acceleration. To bring the project duration back in line with the original schedule as per the contract, acceleration was required. This was carried out on the Shaft Construction C-8.1, which was initially set to take 80 days but was shortened to 63 days through time acceleration, incurring a cost of IDR 23,279,288.

Abstract

Provision of Sports Prasarana is an attempt to fulfill the basic rights of the public to obtain services in sports activities, as listed in Law of the Republic of Indonesia Number 11 of 2022 concerning Sports 2022. The growing automotive industry is one important sector that significantly contributes to Indonesian economic growth. Based on the Surabaya City for 2021-2026 calls for the creation of an integrated area, with the Gelora Bung Tomo area serving as an international sports center and integrating with the growth of trade and service functions in Surabaya's surrounding areas. The aim of this study is to measure the amount of investment income and revenue limits in an effort to reduce the risks associated with the investment in the circuit. We carry out flow calculations using the Net Present Value (NPV), Internal Rate of Return (IRR), Benefit Cost Ratio (BCR), and Payback Period (PP) methods, and then analyze the sensitivity. We reviewed the sensitivity analysis based on several parameters, including commercial rent income and circuit management costs. The development of Tomo's Gelora Circuit is sensitive to a loss of income from the rental of business or commercial premises of 8%, which will affect a decline in profit, resulting in a negative net present value (NPV) and prolonging the rate of return. Additionally, it is sensitive to an increase in management costs by 12%.

Abstract

The rescheduling of the initial schedule carried out on the Bahtera Elang Perak Indonesia Office Construction project has an impact on increasing the duration of work causing the project completion target to be delayed from the time it should be. Increasing the project completion target can affect the amount of costs incurred. The contract value for this office construction project is Rp. 13,908,226,157 with a work duration of 43 weeks to 54 weeks.  The current condition of work progress at week 31 is -0.225% while the total actual cost or that has been incurred during the work is Rp. 3,191,740,254. To overcome this, an analysis is carried out on the value of the estimate at complete (EAC) and time estimate (TE) of the Surabaya BEPI Office Construction Project using the earned value method. This method combines the elements of cost, schedule, and work performance.  The earned value method aims to determine the estimated cost and time of project completion. From the results of the analysis conducted in the 41st week, it was obtained that the estimated cost and time to complete the project implementation (EAC) was 14,289,833,105, - and the estimated time (TE) was 499 days, which was 121 days later than the original schedule.

Abstract

Effective time management is essential for ensuring project implementation aligns with the planned schedule, and one way to achieve this is through the use of Earned Value Analysis (EVA). EVA is employed to estimate the extent to which a project is progressing according to its work plan. This research aims to analyze the timeline of a road construction project using the Earned Value Analysis Method to estimate the final project completion time on a monthly basis. The methodology employed in this study involves the application of the Earned Value Method over a project duration of 18 months. The importance of the Earned Value Analysis Method lies in its ability to assist both the project owner and implementer in more easily analyzing the project's performance, thereby providing significant benefits for both parties. The study found that the project completion time did not align with the initial project schedule. Specifically, the calculation of the cumulative project completion time was 9 months, whereas the planned duration was 18 months. This indicates a delay of 7 months beyond the planned schedule.

Abstract

This research aims to determine community empowerment-based self-management construction projects and contractual-based construction projects in Sumenep District, using the AHP (Analytical Hierachy Process) method. The AHP method is used to analyze the results of the questionnaire so that the weight value of the criteria and sub criteria can be known as the basis for selecting the implementation of construction activities. Based on the results of the analysis of alternative construction implementation contractual weight is 0.501 and community empowerment is 0.499. The implementation of contractual-based construction projects is preferred with consideration of a more organized implementation, both in time (time schedule) and regulations governing it such as sanctions and fines when there are obstacles in the field being part of the responsibility for the implementation of contractual-based construction. Contractual-based construction implementation tends to be more organized and in accordance with strict schedules and regulations, including sanctions and fines if there are obstacles in the field. In contrast, self-managed construction based on community empowerment, such as in the village fund program, often has leeway in terms of a longer implementation period and supervision carried out by the community itself, not by experts. Thus, stakeholders are expected to clarify the regulations governing which works are carried out in a self-managed manner and which works are carried out contractually in government programs.
