- Dari Sabang sampai Merauke song created by R. Suharjo-
If foreigners ever asked us as Indonesian about what Indonesia is, we must be remember that song. Maybe most of us will answer that Indonesia is a country which is located in South East Asia, between Hindia and Pacific ocean and it stretching from Sabang until Merauke. Therefore, lets imagine if the foreigners continue their question, what else Indonesia is? If Sabang is in the west and Merauke is in the east of Indonesia, how about the north and the south of Indonesia? And if Indonesia is located between Hindia and Pacific ocean, then how far it's limit? Who is Indonesia's neighbor?
