Abstract

The Moluccas has a large and diverse natural resource potential which is spread over several islands. To accelerate economic growth in its small islands, the government applies the concept of island clusters. The island cluster in the Moluccas is divided into 12 island clusters based on the shortest distance between islands, similarity in ecosystems, natural resource potential, economic system, transportation, and infrastructure. This paper discusses the design of distribution models to build inter-island connectivity based on archipelagic commodities in the Moluccas. The model is built using by bi-objective insular traveling salesman model. Each island cluster will have its local loop determined based on the distance and potential of its natural resources. Each local loop will be served by a port that will build a global loop. The objective function of this research is to minimize maritime and ground transportation costs. This model can be used to solve the problem of distribution in the island zone.
