Purpose: The purpose of this research is to develop an inter-organizational model of coordination in hinterland chain of hub-and-spoke in export trade logistics, where dryport works as a spoke and seaport as a hub. Design/methodology/approach: The model defines a conceptual model that coordinates several actors involved in handling the flow of goods and the information (documents) for exporting goods via dryport, where their activities are interdependent. The first step of modelling investigated an existing business process of export system via dryport. The second step designed a conceptual model that simplified this business process by splitting it into stages: (1) identifying waste; (2) waste analysis; (3) benchmarking of logistics coordination in selected countries; and (4) streamlining the process. Several alternatives conceptual model of coordination are proposed, in which the development is based on inter-organizational system (IOS) approach. The model is then evaluated by experts to choose the best conceptual model of coordination that suits the real system, especially in Indonesia. The chosen model was then being validated by developing simulation using agent-based approach and discrete-event simulation. Findings: The overaching findings of this research is coordination mechanism in logistics export process. There are two basic mechanisms in document preparation, three basic mechanisms in quarantine inspection, and three basic mechanisms in inland transportation and handling. These mechanisms were used to develop a conceptual model to improve the effectiveness of logistics export process. The coordination in proposed model used a central coordination hub (N:M or N:1:M). Originality/value: The paper improves the inter-organizational system among involved actors for exporting goods via dryport (hub-and-spoke typology). Moreover, this paper improves hinterland coordination that considering flow of goods and information, which was rarely done by other researchers.
