The project is an activity carried out to products or services that have specific scheduling. Scheduling is determined by the relationship between activities made very detailed and accurate. Therefore, the purpose of the final task is to know how to implement the Critical Path Method (CPM) and Program Evaluation and Review Technique (PERT) in scheduling the project, which originally used the Bar Chart method with a duration of 140 days and resulted in a cost of Rp. 5.500.000.000. From the calculation result of this final task in using the CPM, the method generates a period of 105 days and provides cost after crashing in the labor increase of Rp. 5.568.464.052 and the increase in working hours (overtime) Rp. 5.603.725.490. While using the PERT method generates a period of 109 days and generates the cost after being crashing in the labor increase of Rp. 5.574.721.755 and the increase of working hours (overtime) of Rp.5.612.082.633 with a projected probability of reaching the target of 84 %. Has a comparison with the difference in cost of Rp. 6,257,703 in increased workforce and Rp. 8,357,143 other than working hours.Proyek merupakan suatu kegiatan yang dilakukan untuk menghasilkan produk / jasa yang mempunyai penjadwalan tertentu. Penjadwalan ditentukan oleh hubungan antar kegiatan yang dibuat sangat rinci dan akurat. Oleh karna itu tujuan dari artikel ilmiah ini adalah untuk mengetahui bagaimanakah penerapan metode Critical Path Method (CPM) dan Program Evaluation and Review Technique (PERT) pada penjadwalan proyek tersebut yang awalnya  menggunakan metode Bar Chart dengan durasi waktu 140 hari dan menghasilkan biaya sebesar Rp.5.500.000.000. Dari hasil perhitungan artikel ilmiah ini dalam menggunakan metode CPM menghasilkan jangka waktu 105 hari dan mengasilkan biaya setelah di crashing dalam penambahan tenaga kerja sebesar Rp. 5.568.464.052 dan penambahan jam kerja (lembur) Rp.5.603.725.490 Sedangkan menggunakan metode PERT menghasilkan jangka waktu 109 hari dan menghasilkan biaya setelah dicrashing  dalam penambahan tenaga  kerja  sebesar  Rp. 5.574.721.755  dan penambahan   jam kerja (lembur) Rp. 5.612.082.633. dengan probabilitas proyek  mencapai target 84%. Mempunyai perbandingan selisih biaya sebesar Rp. 6.257.703 dalam penambahan tenaga kerja dan Rp. 8.357.143 dalam penambahan jam kerja.

CV. ABP a construction company worked in infrastructure building development for private and goverment. Now CV. ABP is handling infrastructure development project of the acropolitan area (Right Payment) Sukaci - Baros Village. This project has been late for 19 days from the dead line 126 days. Therefore the cost is getting higher. It’s happened because bad management is the problem source. Restoring the project time need to be focused on the cost and the due date based on the schedule. Scheduling evaluation using Critical Path Method (CPM) and Crashing to find optimal results using Critical Path Method (CPM) can be found the critical paths activity, there are ground digging , bopflang installation, stone installation, agregrate B agrgregation , aggregate A flatting, rigit bavement work, and refining, when the time suppression obtained optimal time results from 126 days to 92 days. It taken an alternative to the addition of working hours with duration 92 day after the crashing. Using two alternatives, additional working hours and the addition of workforce, obtaining the difference of extra hours of work cost Rp 80.128.125 and labourcost increase Rp 55.260 from the regular cost.

The project acceleration by the Crash Program is one of the ways that is often used to make time and cost efficiency on an ongoing project. Acceleration of project completion time will affect the efficiency of equipment and labor productivity. In the case study of the Surabaya Outer East Ring Road Project Construction Segment 1, a project that has the potential to be accelerated is discussed in order to obtain efficiency values in terms of time and cost, Project acceleration by means of the Crash Program using the Precedence Diagram Method (PDM) method to determine the value of efficiency. This project uses resources, in this research the software used is Microsoft Project 2016. The research method used is to design network planning, find the critical path for each job, determine the work that has the potential to be accelerated, calculate the crash cost in additional working hours. and work shifts, calculating direct costs and indirect costs for each activity that changes due to changes in the duration of implementation, calculating the cost slope. Application of the Crash Program in the work of Asphalt Concrete Surface Layers (AC) thick 5 cm in the project will have an impact on increasing the time efficiency previously planned from 180 working days to 175 working days and efficiency with the difference in project costs of Rp. 18.313.935,8 with a ratio of 0,997 between the PDM method compared to the cost of the contract value calculated using the crashing project method.

“Spark spread” refers to the difference between the cost of electricity and the cost of fuel on a per-MMBTU basis. This metric is often considered when recommending equipment retrofits that require fuel switching. A spark spread of at least $12 per MMBTU is considered the threshold for economic viability of Combined Heat and Power (CHP) systems. However, this study shows that an increase in the electric utility rate has an impact on the spark spread required to maintain the economic viability of a CHP project. This challenges the paradigm that a single value for spark spread can be used as a “rule of thumb” for determining the economic viability of CHP projects. As utility rates increase, so does the importance of understanding the relationship between spark spread and the economic viability of projects.

At the end of a conceptual design phase, engineers choose a single (or a small set of) system concept from a large number of concept variants. In most cases, there is not enough design information to quantitatively evaluate how a final system developed from each concept would perform and cost. Thus engineers need to first perceptually evaluate and select a concept, and then design a system. On the other hand, if engineers know analytical relationships between system and part requirements, they can specify target values of part requirements such that a system achieves its target requirements. Furthermore, if engineers know how much it will cost to control part requirements within tolerances, they can minimize the cost of a system by optimizing tolerances of part requirements. This paper proposes and illustrates an approach to select a system concept when engineers know the relationship between system and part requirements, and how much it will cost to control part requirements within tolerances. Engineers choose a concept that minimizes cost.

The study aimed to identify the relationship between talent management and enhancing the competitive advantage of some sports federations in the Egyptian and Bahraini societies, in addition to the difference in this according to the variables of both experience and level of employment. To achieve this, the researchers used both Talent Management and Competitive Advantage quetionair as a tool to collect data and information from a sampling sample of (50) and a core sample of (247) board members and employees of Egyptian and Bahraini sports federations. The results of the study showed that there is no relationship between the methods of managing human talent between the Egyptian and Bahrain sports federations. There is a positive relationship in the quality of talent in the Bahraini unions and creativity in the Egyptian and Bahraini federations. The results also indicate that there is no difference between the Bahraini and Egyptian federations in the management of sports talents and the promotion of competitive advantage due to the variables of experience and level of employment. Researchers have recommended that specific criteria be used to attract sports talent and retain competencies to reduce the cost of spending on sports talent.
