【 摘 要 】

Bunaken sea is one of the fisheries source for Manado and around it. But unfortunately, some studies have shown that the coral reefs in some parts of Bunaken Sea have been deteriorating. Some of the causes are coral retrieval, illegal fishing using explosive and poison, marine pollution, and sea temperature increase. Deteriorated reef can be recognized through the color becomes white or known as coral bleaching. In order to preserve coral reefs, there are some factors that can be learned. One of the factors is the location of the healthy coral reefs and can produce coral larval to help recovery process of the deteriorated reefs. Based on some research, coral larval dispersion will be modelled using Graph Theory that is objects connectivity, especially the Hamiltonian Path. Reef spots are represented by vertices and dispersion paths are represented by edges. Based on research, the first location that must be conserved is M23 because it gives good impact and has high possibilities to help recovery of the other 16 locations. Research about determine the coral larval dispersion path can be used to help coral reef conservation to minimize the time and budget, also can support the development of marine, fisheries, and tourism.
