摘要:This paper examines the damage to the marine and coastal environment in Aceh. This happens because human behavior does not care about environmental safety in exploring marine resources. However, on the coast of Aceh there is one wisdom value that can limit human behavior, namely Panglima Laot. Panglima Laot is a maritime cultural heritage from the Kingdom of Aceh to the republic. Panglima Laot is the result of the adaptation of the structure of the Kingdom of Aceh into the structure of coastal culture in Aceh. This coastal wisdom is a major asset as a social infrastructure in limiting human behavior to ensure environmental sustainability. The research method used in observing this maritime social phenomenon is a qualitative method with sociological and anthropological approaches. The results showed that Panglima Laot has a social system that promotes environmental sustainability. This system is able to limit human behavior in exploring the natural resources of the coast and the sea. In general, the social system owned by Panglima Laot is divided into three, namely hukom adat laot, adat laot and hukom meupayang. This is a significant value in limiting human behavior for the sake of the sustainability of the coastal environment.
