ANALISIS PENYEBAB DAN DAMPAK KETERLAMBATAN PROYEK MENGGUNAKAN METODE FAULT TREE ANALYSIS DAN EVENT TREE ANALYSIS PADA PEKERJAAN PINTU JENDELA ALUMINIUM (STUDI KASUS PROYEK ITB INNOVATION PARK BANDUNG)

Abstract

Project delays are often difficult problem to avoid. Aluminum door and window installation plays a crucial role in building. These components are often the final elements in the finishing process, so these delays can impact the project schedule. The ITB Innovation Park Bandung project used approximately 650 aluminum frames. The work was scheduled for completion in June 2024, but was only completed at the end of October 2024. The purpose of this study was to determine the main risk factors causing delays and to determine the impact of delays in aluminum door and window work on the ITB Innovation Park Bandung Project.

This study uses the Fault Tree Analysis (FTA) method, explaining various interactions that cause delays. Furthermore, the Event Tree Analysis (ETA) method is used to assess the consequences of an event by mapping a series of possible outcomes. FTA and ETA play an important role as a basis for assessing the risk level of project delays in the installation of aluminum doors and windows for the ITB Innovation Park project. The method used is the distribution of questionnaires to respondents. The questionnaire results contain primary data used for analysis in the study.

Identification of factors causing project delays through FTA with two dominant aspects, the production process does not run according to plan with a probability of 0.970 and a suboptimal project management system with 0.861. The probability of project delay is calculated by combining the minimum cut set of factors in FTA, showing a high probability of 0.958, reflecting systemic delays and involving many project elements simultaneously. The impact of delays based on ETA, the more failed pivotal events, the project risk increases significantly. ETA shows the highest risk of suboptimal preventive controls with the "high" category according to the risk matrix.
