Development of business processes on sustainable procurement based on identification of policy and institutional factors in the LRT TOD apartment project

Sustainable procurement through construction procurement has considerable potential to advance a project's sustainability strategy in which the procurement of products, equipment, machinery, and services is an important aspect, especially in high-rise buildings. One of the main factors is the lack of policies and support from organizations for the proper and precise implementation of sustainable procurement. Currently, there are no structured guidelines for compiling business processes that are in accordance with project conditions in LRT TOD Apartments. The purpose of this research is the development of business processes for sustainable procurement based on identifying policy and institutional factors in the LRT TOD Apartment Project. The method in this study used three procurement experts to validate policy and institutional factors. With the expert's assessment, various factors were obtained on sustainable procurement policies and institutions, which could become the basis for business process development. The results of this study show that the existing procurement business process is improved based on integrating policy and institutional that correlate with each other to develop a sustainable procurement business process model for the LRT TOD apartment project.
