Pembangunan LPG Refrigerated yang terletak di tuban, Jawa Timur saat ini sedang dalam proses pembangunan. Pengerjaan proyek direncanakan dalam waktu 399 hari dengan nilai total proyek sebesar Rp. 14.584.800.000. Selama pelaksanaan proyek sering mengalami keterlambatan aktivitas pekerjaan yang menyebabkan durasi waktu penyelesaiannya mengalami kemunduran dari jadwal yang telah ditentukan. Akibatnya terjadi penundaan waktu untuk memulai aktivitas pekerjaan berikutnya. Hal tersebut tidak hanya menambah durasi umur proyek, akan tetapi juga mengakibatkan pembengkakan anggaran biaya. Banyak faktor yang menyebabkan keterlambatan penyelesaian terhadap suatu pekerjaan meliputi penyediaan bahan baku, keadaan alam, letak geografis dan berbagai unsur lainnya. Dengan demikian perlu diadakan analisa untuk mempercepat durasi proyek, dimana pada penelitian ini akan menggunakan metode Critical Path Method (CPM) dan Time Cost Trade Off (TCTO) untuk melakukan percepatan durasi waktu pada aktivitas yang berada dijalur kritis. Hasil Perhitungan dengan metode Time Cost Trade Off didapatkan durasi dan biaya optimal proyek pembangunan LPG Refrigerated yaitu selama 364 hari dengan penambahan 1 jam lembur yang dapat mempercepat proyek hingga 35 hari dari durasi normal yaitu selama 399 hari dengan total tambahan biaya sebesar Rp. 235.580.228.
ABSTRACT
The development of a Refrigerated LPG located in Tuban, East Java is currently under construction. Project work is planned within 399 days with a total project value of Rp. 14,584,800,000. During project implementation, work activities often experience delays which cause the duration of the completion time to experience a setback from the predetermined schedule. As a result, there is a time delay to start the next work activity. This not only increases the duration of the life of the project, but also results in an increase in the budget. Many factors cause delays in the completion of a work including the supply of raw materials, natural conditions, geographical location and various other elements. Thus it is necessary to carry out an analysis to accelerate the duration of the project, which in this study will use the Critical Path Method (CPM) and Time Cost Trade Off (TCTO) methods to accelerate the duration of time for activities that are on a critical path. Calculation results using the Time Cost Trade Off method obtained the optimal duration and cost of the Refrigerated LPG development project, namely for 364 days with the addition of 1 hour of overtime which can accelerate the project by up to 35 days from the normal duration, which is 399 days with a total additional cost of Rp. 235,580,228.
