Most of the national transport using sea transportation, especially the eastern part of Indonesia. Characteristics of geography on
land and sea and the existing infrastructure in eastern Indonesia supports the transport more efficient use of sea transport. However,
the cost of logistics in eastern Indonesia is more expensive than the West. The effort to improve the connectivity between ports in
Indonesia, particularly Eastern Indonesia is believed to be able to reduce the cost of logistics that exist today. The aim of this study
is to analyze the connectivity between ports in eastern Indonesia. The analysis is using Gravity method. The results of this study
are expected to know how to rate density of connectivity ports eastern Indonesia. Based on the existing level of connectivity density,
the analysis regarding the pattern of connectivity between ports in eastern Indonesia become more efficient and policy
recommendations needed to improve the connectivity between these ports have conducted.
