As an Indonesian national strategic project, the Port of Kuala Tanjung draws significant attention at national and international level. Considering the semi-greenfield nature of the port, the diverse set of stakeholders, and the prevailing disruptive trends in the world port business enabled mainly by digitalization and energy transition, a robust 1st phase port layout is required to kick-start the project and guarantee the overall sustainability of the port development. This thesis is conducted on the Port of Rotterdam Authority (PoRA) which is a part of the Joint Venture company that is responsible in developing the Port of Kuala Tanjung. The author would like to clearly state that while this study is conducted during the author's internship at Port of Rotterdam, the views expressed in this paper are those of the author alone and not the Port of Rotterdam Authority.. The objective of this research is to develop an adaptive port masterplan along with its robust 1st phase layout which is self-sustainable and provide catalyzing effect for the next stage of development. A modified Adaptive Port Planning (APP) framework will be used as the main methodology in this research. In addition, the United Nation Sustainable Goals is being used as a guiding principle in planning the port. A combination of a literature review and interviews with experts are used to both identify the sources of the uncertain and disruptive trends mentioned above and also to propose adaptation strategies. As a conclusion, an adaptive port masterplan has been developed. A circular economic concept combined with industrial port complex model has been applied to the port to incorporate self-sustainability and catalyzing effect element into the port. To validate the research products, series of interviews and FGD has been conducted with Port of Rotterdam Authority experts.
