The problem faced by Indonesia at this time is the lack of information related to supply and demand related to the productivity component, so it needs a study to formulate an index of construction productivity in Indonesia. The analysis of the determination of the productivity component is carried out by the desk study approach with the standard of construction productivity calculation, the standard for construction work financing, and mapping analysis approach based on project technical document data from 3 Unor, namely Water Resources, Highways, and Cipta Karya. The mapping analysis results obtained that the Workforce Component consists of Experts, Skilled Workers, and Non-Skilled Workers, Work Equipment Components include heavy equipment and light equipment and Construction Material Components. Experts for Unor Water Resources consist of Water Resources Experts, Quality Management System, and K3 Construction, Unor Bina Marga, namely Road Engineering, Bridge Engineering, Quality Management System and OHS Construction. Unor Cipta Karya’s experts consist of Environmental and Sanitation Engineering, Environmental Sanitation, Project Management, and Construction Management Experts. Skilled Workers from 3 Unor, namely Supervisors, Measurers, Land Mapping, Road Implementers/Irrigation, and K3 Officers. Non-skilled personnel consist of administrative and financial staff.
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.

This study aims to obtain a process flow model of an organizational function that functions effectively in increasing the accuracy of project cost estimates at the auction stage by including implementation elements from a combination of 2 BIM and ERP systems in it. The location of the research was carried out in a state-owned contractor company, namely PT. Nindya Karya (Persero). This state-owned company has used ERP and BIM in its business processes. The methodology used in this study is a questionnaire-based primary data research where data relating to the development of process flow involving BIM and ERP elements in it have been collected from the Estimating department unit in the company PT. Nindya Karya. The questionnaire was developed to evaluate the importance of implementing BIM and ERP in improving the accuracy of cost estimation identified through responses obtained from the respondents to the questionnaire survey. The research data are then processed using Flow chart analysis techniques. The results of the study obtained that the process flow model of the estimating department of PT. Nindya Karya has currently implemented BIM in the tender calculation process, but has not involved ERP elements. The final result of drawing conclusions in this study is in the form of a workflow flowchart or process flow from the estimating department which in the process involves 2 BIM and ERP systems.
Infrastructure development must pay attention to basic aspects such as technical and social infrastructure. A special approach is needed to achieve sustainable development that adopts three main pillars in infrastructure development such as economic, environmental and social disparities. The absence of a holistic sustainable construction model requires a comprehensive solution by conducting an in-depth study to formulate the right model in implementing sustainable construction. The aim of this study is to build a holistic sustainable construction proposal model, which is expected to be a standard model so that it can be a guidance for stakeholders in implementing Sustainable Construction in the Likupang special economic zone (SEZ). This study used a quantitative method by structural equation modeling (SEM), as a multivariate analysis technique to examine the relation between complex variables and to obtain a comprehensive picture of the entire model. The sample used was 80 respondents. The results of this study indicate that the model built 56.8% has been fit and ready to be implemented. The results also show that economic and government factors have a positive and significant impact on sustainable construction. This study concludes that the model built is good and can be implemented in the Likupang SEZ.
The progress of multi-story building construction in Indonesia especially in developing regions such as Makassar City during the last ten years has experienced significant development. Where the proportion of overcast contributions due to the emergence of remaining material during building construction ranges (3-13.5)% which of course directly impacts the overall construction costs. The purpose of this study is to identify the remaining management factors of construction materials that are ideal for implementation by construction operators, conduct control assessments on the relationship of the effect of the application and potential management of the remaining construction materials to the impact of construction cost performance. The method used in this study was carried out by determining the population and sample number of building construction projects currently underway and a survey of the number of contractor representatives in Indonesia then collecting primary data in the form of distributing questionnaires to construction organizers, especially to experienced contractors, then subsequently. The expected results of this study are to obtain a management model concept for the remaining cost of building construction materials in the ideal construction stage that can be applied by the construction operators in this case to the implementing parties/contractors.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
