Productivity is one of the fundamental factors affecting competitiveness in the construction industry. Construction and productivity are two things that are interrelated. This study aims to identify the factors and model relationship these factors that affect labor productivity using the Structural Equation Modelling (SEM) in road construction projects in Indonesia as seen from each side area I, II, and III, respectively. The results obtained the factors that influence labor productivity in road construction projects in Indonesia, namely field conditions, time, financial factors, and internal labor. The study's findings indicate that internal labor is one of the elements influencing labor productivity in Indonesian construction projects, particularly road maintenance work. Labor productivity research in Indonesia is conducted by comparing planned and realized labor productivity calculations, which are conducted by collecting project data and making firsthand observations of work in the field. Labor productivity is measured using characteristics other than the variables used in the research, as well as a larger population and sample coverage. The findings of this study can be utilized as input for government agencies in determining the ability of specialists to carry out work in the field connected to the preservation of non-structural flood handling roads on Indonesian territory. Doi: 10.28991/CEJ-2023-09-03-07 Full Text: PDF

Many challenges are faced in implementing sustainable construction in Indonesia. This research aims to find an effective method for adopting sustainable construction. The method used combines qualitative and quantitative methods by incorporating the identification of significant factors affecting the adoption of sustainable construction. In data collection with the SWOT system, FGDs and interviews provided accurate information regarding factors and strategies to promote sustainable construction, particularly in the Likupang SEZ Project. From the results of the study, the IFSC value for the promotion strategy of sustainable construction in the Likupang SEZ project is the social factor of 0.2, followed by the economic factor of 0.3, the environmental factor of 1.2, and the government support factor, business investment, and cultural factors of 1.4, respectively. The highest IFSC value was obtained for the human resource factor of 1.6. Thus, it can be concluded that human resources must be accompanied by government support along with business investment and cultural influences in order to realize adequate sustainable development projections for the Likupang SEZ project in the future. Doi: 10.28991/CEJ-SP2023-09-07 Full Text: PDF
