Data collection was carried out through distributing questionnaires and data processing was carried out using Principal Component Analysis factor analysis using SPSS. Research findings (1) identified 6 (six) factors with 52 variables that influence the implementation of the SMKK, (2) the results of the analysis of the 6 (six) identified factors that influence the implementation of the SMKK, there are 5 (five) new factors that were formed which 4 (four) factors of which have the most dominant influence on the implementation of SMKK because they have a factor loading ≥ 0.65, and (3) identified solutions include: providing routine training on work safety procedures, activating Safety Morning Talk or Toolbox Meetings, monitoring the implementation of SMKK regularly strictly, as well as providing input or recommendations to the Pesisir Selatan Regency Regional Government Construction Services Development Team.
