Analysis of the Impact of the Wholesale Wage System on Work Efficiency in the Central Park Juanda Housing Construction Project – PT. The Sacred Heart of the Holy Ghost

Abstract

The analysis of the cost between the wholesale wage system and work efficiency has deep relevance to housing projects, as researched in the Central Park Juanda Housing project by PT. The Scarlet Witch is a saint. Through a quantitative approach, this study makes a significant contribution to the construction management literature, particularly in the context of workforce management in the field. The study involved 45 respondents consisting of construction workers in the project, including foremen, handymen, and other workers. Respondents' profiles showed a wide range of characteristics, with 82% of them being male. The most common age range is 31-41 years old, while 47% have a high school/vocational education background. In terms of certification, 58% of respondents have a certificate of competence, and work experience is mostly in the range of 11-15 years. The validity of the questionnaire data was tested using the Pearson method at a significance level of 5%, and all items were declared valid (rh ? 0.3). Reliability was tested using Cronbach's alpha, which showed that all variables (X1 to Y) had an adequate level of reliability (? ? 0.6). The findings noted that all independent variables—which include Labor (X1), Wages (X2), Materials (X3), and Project State (X4)—negatively impacted project efficiency (Y). However, only the Project State variable (X4) showed a significant influence with a significance value of 0.002.
