In every good working environment should prioritize the safety and health of its workers properly and reasonably. In the world of construction, especially high rise building is needed the safety program. Occupational Safety and Health nowadays is not only implemented in the course but starting from the preparation, implementation until the end of work. However, in its implementation, there are few obstacles because there are still many human resources, especially in the limited project area, in understanding the implementation so that the work safety program is not yet a top priority. If these conditions are allowed to continue, the risk of work injury will certainly continue to grow. So to find out what factors make the construction project area is still not optimal to implement the safety program, the researcher highlighted the case on mixed use development project as high as 37 floors and with the development time targeted quickly and on time. So what is the most appropriate factor to improve the implementation of safety on the performance so that the work can be completed according to planned and timely results. The data collected in this research is quantitative using survey for workers in construction area of X Surabaya Project who are in the field everyday. The number of samples is 85 respondents from 243 people, then only a part of the population. The independent variables consist of Top Management Commitment (X1), Personal Protective Equipment (X2), Supervision (X3), and Awareness (X4) while the dependent variable is Performance (Y). Data is processed using validity test and reliability test, while the method of data analysis using multiple linear regression and FGD method, firstly the validity and reliability using SPSS statistical program. The results of this research indicate what safety measures are most influential and should be considered in the implementation of Occupational Safety in the area X Surabaya Project. Occupational safety factors that significantly affect the worker’s performance are Personal Protective Equipment (PPE). Then reanalyzed with Focus Group Discussion (FGD) in order to find a best solution in the implementation of Occupational Safety so that it can be a revamping in the company’s performance in the future.
