Risk Analysis of Work Accidents in The Building Revitalization Project “Y” City Semarang by PT. X with Fault Tree Analysis (FTA) Method

The construction industry is hazardous due to its tendency to cause accidents. In constructing a multi-storey building, one of the risks that has the potential for work accidents is the risk of falling from a height. This research was conducted on the “Y” building revitalization project in Semarang city. This study aims to analyze the factors that are the basic causes of unwanted events in the project's revitalization using the Fault Tree Analysis (FTA) method. This research is descriptive observational research with analysis based on field observations and supported by literature studies from previous research. The results showed two of the most dangerous risks, namely "workers being hit by falling materials from a height" during advanced structural work, and the risk of “falling from a height” during advanced structural work and installation work. When applying the FTA model, 16 root causes were found for both risks. To minimize these risks, it is necessary to take mitigation measures such as paying attention to one's physical and mental condition before working, always complying with applicable SOPs, and wearing complete PPE.
