Pengendalian Durasi Optimal pada Pembangunan Myze Hotel Sumenep Menggunakan CPM dan Metode PERT

Abstract

The project owner expressed a desire to accelerate the project to avoid delays. According to observations and progress reports, the week 45 progress was 76.071% with a deviation of -7.894%. The delay was caused by the contractor's poor time and cost management which affected the project implementation. Warning letter 1 is given by the owner so that the contractor evaluates and accelerates implementation. Time control is required, as well as time optimization analysis using the PERT method for a more efficient and faster duration. PERT focuses on scheduling with synchronization of project elements, taking into account the uncertainty of the duration of tasks and the overall project. This research aims to identify project duration control by applying PERT and CPM methods, as well as exploring the cost of potential project acceleration through subcontractor integration. Data collection techniques are through project observation and documents such as cost budget plans, S-curves, progress reports, and reference drawings. This data is used to analyze the optimal time through identifying critical activities with CPM and determining the optimal duration using PERT. Alternative project acceleration with the addition of subcontractors. In the research results, the CPM method identifies critical activities such as procurement, piling, connection, and cutting pile heads, from the PERT method the optimal duration is 45 days, with a probability of 59.18%. Alternative acceleration by applying subcontractors occurred cost savings of Rp. 84,855,111.02 or 1.11% of the total normal cost so that the cost of acceleration with subcontractors amounted to Rp. 7,547,781,459.38.
