The value of construction projects in Indonesia is significantly enhanced by partnering, leading to the adoption of the model by the government. The Indonesian government, through the Ministry of Finance, is developing the partnering model based on Public–Private Partnerships (PPPs) projects to further accelerate extensive infrastructure development. By leveraging PPPs, these projects intend to bridge the funding gap experienced by the government to facilitate swift infrastructure development and enhance the value of construction projects even further. Therefore, this study aimed to examine PPPs, such as the solicited projects occurring in Indonesia. Solicited projects were government-initiated PPPs based on long-term development plans. A qualitative method was adopted, conducting in-depth analyses at three locations with solicited PPP projects. Using Soft System Methodology (SSM) and expert Focus Group Discussion (FGD) through the Delphi method, this study investigated the interactions and depth of partnering in PPP projects. The obtained results emphasized the positive impact of solicited projects on Indonesian infrastructure development, addressing the funding gap experienced by the government. This study further contributed new insights for stakeholders and academics in the development of the projects in Indonesia, emphasizing the necessity of extensive development to support the implementation.

The construction industry is naturally complex and constantly changing, with various factors impacting project results. Among the different methods developed to navigate this complexity, partnering is believed to increase project value and performance. Therefore, this research aimed at analyzing and formulating elements as well as indicators at each phase of a partnership-based project life cycle, serving as tools and techniques for measuring the depth of partnering in construction projects. The methodology used included both qualitative and quantitative methods (mixed method). In the qualitative method, the literature from relevant journals, books, and previous research was reviewed. This process was followed by an expert assessment through a Focus Group Discussion (FGD) to define elements and indicators for measuring the depth of partnering in construction projects. Meanwhile, the quantitative method comprised analyzing secondary project data to compare projects with in-depth partnering in order to deliver better value. The result of this research was the development of Key Performance Indicators (KPIs) to measure maturity partnering in partnership-based projects. Typically, the tools were adjusted to different phases of the project life cycle, starting from project initiation, comprising all stakeholders. Consequently, the outcome of this research could be used by organizations in the construction industry to develop partnering in partnership projects in Indonesia. [ABSTRACT FROM AUTHOR]

Many projects in Indonesia have implemented new strategies in response to the COVID-19 outbreak. Many projects suffered unexpected losses during the COVID-19 pandemic, and conditions were unpredictable. This situation must be considered by all stakeholders participating in a project. Another problem in the implementation of construction is the fragmentation between project participants. Therefore, a strategy is needed in each phase of the project life cycle. In the absence of proper planning, the contractor is the party responsible for bearing the risk associated with this occurrence. Improved project performance is a shared responsibility among owners, contractors, designers, and subcontractors, all of whom need to tap into their own sources of creativity and innovation. The potential of partnering as a tool for achieving lean construction performance, it is still in its infancy as a means of enhancing project outcomes. In this study, we used qualitative methods and in-depth interviews enhanced by focus group discussions of 14 experts (owners, designers, contractors, and academics) using the Delphi method. The results illustrate the maturity of partnering in integrated project delivery (IPD); therefore, its guiding philosophy can be developed and implemented to improve the outcomes of construction projects in terms of cost, quality, schedule, health and safety, and environmental performance. The most important part of this research is related to the implementation of the 17th goal of the Sustainable Development Goals (SDGs), i.e., partnerships to achieve the goals. This research contributes to a deepening of partnering practices that can drive performance in project implementation. [ABSTRACT FROM AUTHOR]

Purpose: This paper aims to identify the barriers for implementing Reverse Logistics in the construction sector and to rank the barriers between the barrier and the stakeholder, the phase in the project life cycle, and the relevant issues on the emergence of barriers in implementing reverse logistics Design/methodology/approach: This research began by identifying barriers re-verse logistics through a systematic literature review. The method used in the systematic literature review was the PRISMA method. The identification of barriers was assessed for their influence on reverse logistics' successful implementation by the expert using a questionnaire instrument. The rating scale used was a Likert scale of 1 (greatly hinder the implementation of reverse logistics) to 5 (not greatly hinder the implementation of reverse logistics). The results of the expert assessment were used to rank barriers using TOPSIS. Findings: There were 38 barriers in this study, classified as: markets and competitor's issues, policy issue, supply chain process, economic issue, knowledge-related issue, government support issue, and operational issue. This study's results indicated that the lack of governmental support for the implementation of RL (GS1) was the barrier with the highest ranking. This barrier was related to governmental support issues and appeared in the project life cycle approach's green initiation phase. The stakeholder who was responsible to improve the GS1 barrier is the government. In this case, the government played a vital role as a regulator and a project owner, who encouraged reverse logistics implementation. Research limitations/implications: The limitation in the scope of this research is specific to the construction sector in developing countries, particularly Indonesia. The object of construction in this study is the case of highway construction. Further research that examines barriers based on the project life cycle by entering the company scale, or study about the relationship between barriers can also be done. Practical implications: This study provides an understanding to stakeholders about the barriers in implementing reverse logistics. The ranking results become a reference for relevant stakeholders in developing a successful strategy for implementing reverse logistics and the PLC approach phases as a guideline for implementing the established strategy. Social implications: The stakeholder of the construction project has to learn with reverse logistics barriers in order to improve reverse logistics performance. Originality/value: This study tries to map reverse logistics implementation barriers in the construction sector in developing countries. The majority of research on reverse logistics implementation barriers examined the manufacturing sector in developed countries. This study also identifies barriers that show the relationship between barrier emergence in terms of the project life cycle approach and stakeholders responsibility for addressing barriers and associated problems. Previous researchers only identified barriers in terms of stakeholder linkages with related issues, so it was challenging to improve efforts based on identifying barriers because they were not guided by a process-based approach such as the project life cycle.

Sustainable construction as a construction method is a beginning to gain traction among Indonesian contractors, but with the dearth of research, knowledge, socialization and strategic support in this field, there are many obstacles towards en masse adoption in Indonesia: to be applied “effectively” and to become part of a “strategic method”. The concept of Sustainable Construction primarily emphasizes the wise use of resources (primarily natural resources), thereby systematically guaranteeing the fulfillment of future needs. However, the use of recycled materials is still hampered by the difficulty of field implementation; this is attested by the low scores attained in green building certification. This study will analyze the strategies needed to support sustainable construction in relation to supply chain management for materials, which have not been implemented well in Indonesia, whereas it has the highest impact in contributing to the effectiveness of sustainable construction. The aim of study is to analyze supply chain performance in materials of construction projects. The measurement used is the Supply Chain Operations Reference (SCOR) model with perfect order fulfillment and overall value at risk as a Key Performance Indicator (KPI). The result of the study is the percentage of material that could be used by the management of supply chain. Once the KPI is more fulfilled by perfect order fulfillment, the use of material is more complete to support sustainable construction. [ABSTRACT FROM AUTHOR]

Knowledge management is a concept of managing of knowledge in the company. The implementation of concept has different levels in each company. Knowledge management maturity is a guide or measure of the company's position in managing of knowledge. The objective of the study is to identify knowledge management maturity in Indonesian construction companies. This study used a survey method and conducted by distributing questionnaires to large construction companies that implement knowledge management activities. Four level of knowledge management maturity was proposed on this study. The results show that 29 contractors at the practiced level, 20 contractors at managed level and 5 contractors at continuously improved level. [ABSTRACT FROM AUTHOR]
