Stakeholder management has an important role in the success of the project because the strategies, plans, methods, and processes for stakeholders greatly determine the success of sustainable construction implementation. Lean construction is one of the principles in implementing sustainable construction by maximizing value and minimizing waste to increase productivity. This study aims to analyze the stakeholder engagement assessment matrix in lean construction, analyze the drivers and barriers in lean construction, and develop stakeholder engagement strategies to improve the implementation of sustainable lean construction. For this study, a questionnaire survey with 61 respondents was used. The data analysis method uses the Certainty Index, RII, Fuzzy AHP, and Fuzzy-TOPSIS. The findings of this research show that there are engagement gaps among stakeholders such as owners, contractors, consultants, subcontractors, architects, the government, local governments, and NGOs. There is no engagement gap between project suppliers and investors. The highest barrier to implementing sustainable lean construction is a lack of knowledge and skills in using lean tools and principles, while the highest driver to implement sustainable lean construction is improved time efficiency and process standardization. The best strategy for increasing stakeholder engagement is by having governments develop regulations and standardize green and sustainable materials.
