Maritime transport plays a critical role in economic development for the littoral member states of the Association of Southeast Asian Nations (ASEAN). In the era of big data, the global marine vessel automatic identification system (AIS) is an important instrument for analyzing the maritime transport network. Aligned with this potential, the Government of Indonesia (GoI) envisions a greater role for the country as the global maritime axis, by setting up several maritime development plans, including "Tol Laut". This study aims to analyze current port connectivity in South-East and East Asia and the further integration of the existing network under the Tol Laut development plan. We use two approaches: betweenness centrality and network efficiency. Betweenness centrality analysis suggests that Tol Laut could reduce ASEAN maritime transport dependency on Singapore. The network efficiency analysis suggests that should Bitung became a hub port in Eastern Indonesia, it would lead to a 20% increase in network efficiency when compared to the status quo, as well as when compared to the model for Sorong as a hub port.
