bay and seaport, East Kalimantan propinsi (province), Indonesia. It is situated on the eastern coast of Indonesian Borneo, facing the Makassar Strait, and is the site of a major oil refinery that processes both imported and local crude oils. There are producing oil fields-which are operated, though they are no longer controlled, by British-American-Dutch interests-that have been in operation there since 1899 as well as in the coastal region stretching approximately 60 miles (100 km) toward the northeast. The refinery was destroyed in 1942 as part of a "scorched-earth" policy, in the face of the Japanese invasion, but it was rebuilt after World War II. Pop. (2005) 440,552.
