The Rank of Factors Affecting Labor Productivity on Construction Projects

Abstract

Human resources or labor is one of the factors that influence the success of a construction project. Based on this
 statement, it is necessary to analyze labor productivity. Many factors can affect labor productivity. This
 research aims to determine the ranking of factors that affect labor productivity in high-rise building
 construction projects in Jabodetabek. These factors are divided into 2 parts, namely internal factors, and
 external factors. Internal factors are factors derived from within labor control and external factors are factors
 derived from outside labor control. The method used in this research is a quantitative research method using a
 questionnaire. Furthermore, this research is analyzed using IBM SPSS software for validity and reliability
 testing and analyzed using the Relative Importance Index (RII) to determine the ranking of these factors.
 Based on the results of the validity and reliability tests, 18 variables were declared valid and reliable. The
 highest ranking of the factors that affect labor productivity when viewed as a whole is work skills which is a
 variable from internal factors with an RII value of 0,906, while the highest ranking of external factors is
 equipment quality with an RII value of 0,883.
