In order to succeed Indonesia’s mission to provide 23.000 MegaWatt, the gas pipeline transmission has been built. The Project consists of many activities that related to each other, If one of the activities are having a problem that caused a delay, then the succeeding activities will get affected and could cause a project’s delay. To anticipate, it needs the acceleration of the project’s activity. In this case, the pipe transmission project would cause a 7 day delay. To accelerate it, this study gives the calculation, using “What If Analysis Method” on “Critical Path Method”. The acceleration actions are treated in accordance with providing extra working hours and the certain amount of manpower in the succeeding activities.

Project Data

Project planning has several stages or project activity plans that can result in the running of a project more optimally to the project estimation that can help the planning manager or project manager work together in preparing project implementation at PT. Pakarti Tirtoagung. PT. Pakarti Tirtoagung is a business that will produce an intangible product (service) / service activity for construction and oil services that will be used for the needs of other companies. Problems at PT. Pakarti Tirtoagung in processing project data using the MS system. Excel which results in data redundancy so it must check data -  data and must be input again. This results in data redundancy and lack of data consistency so the presentation of project manager information is less accurate. Then this research uses CPM (Critical Path Method) method to determine the level of project progress in order to optimize project duration, possibility of accelerating time of project implementation and make it easier as admin by supporting project estimation activities, making it easier to manage planning of project activities and preparing a project scheduling. The design is implemented using PHP and MySQL database servers.

The Relationship

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.

Abstract This study aims is to find the critical path which caused delay on the projects. Several factors which may affect to the delay are the weather, the lack of manpower, supply chain, equipment and so on. The research methodology was conducted to elaborate the causes are by using qualitative and quantitative researches. Over 35 respondents and 10 expert’s interviewee fill the questioner and were collected within two months. The result obtained is accelerated 3 paths from critical path method (CPM) then calculated the crashing program for each alternative. The alternative of acceleration applied are add the working hours in 4 (four) hours and 7 (seven) hours. In the end, the addition of 4 (four) hours could increase the workforce up to 25% of the total number of workers to get the value of accelerated finishing projects without ignoring the quality and quantity of them. Also, the additional labour is more beneficial in terms of costs they have relativity small number of working hours and would be more efficient.

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.

Construction Organization

The construction organization usually takes the Critical Path Method (CPM ) used in the mathematics graph theory, which is a kind of classic system engineering analysis method, was introduced to China by Hua Luogeng – a mathematician, and originally called the Overall Planning Method. This method has been widely applied in various fields of the national economy, especially in the construction field; of course the Overall Planning Method itself has also been greatly developed. Though the Overall Planning Method is relatively mature, there are still a number of uncertainties (random factors) in the construction organization, and it is not easy to make a mathematical description for the Critical Path Method. This paper tries to use random linear programming in the construction organization.
