The many islands forming Indonesia.
The area
Indonesia consists of 17,508 islands, about 6,000 of which are inhabited. These are scattered over both sides of the equator. The five largest islands are Java, Sumatra, Kalimantan (the Indonesian part of Borneo), New Guinea (shared with Papua New Guinea), and Sulawesi. Indonesia shares land borders with Malaysia on the island of Borneo, Sebatik, Papua New Guinea on the island of New Guinea, and East Timor on the island of Timor. Indonesia also shares borders with Singapore, Malaysia, and the Philippines to the north and Australia to the south across narrow straits of water. The capital, Jakarta, is on Java and is the nation's largest city, followed by Surabaya, Bandung, Medan, and Semarang.
At 1,919,440 square kilometers (741,050 sq mi), Indonesia is the world's 16th-largest country in terms of land area. Its average population density is 134 people per square kilometer (347 per sq mi), 79th in the world, although Java, the world's most populous island, has a population density of 940 people per square kilometer (2,435 per sq mi).
the climate & culture
Lying along the equator, Indonesia has a tropical climate, with two distinct monsoonal wet and dry seasons. Average annual rainfall in the lowlands varies from 1,780–3,175 millimeters (70–125 in), and up to 6,100 millimeters (240 in) in mountainous regions. Mountainous areas—particularly in the west coast of Sumatra, West Java, Kalimantan, Sulawesi, and Papua—receive the highest rainfall. Humidity is generally high, averaging about 80%. Temperatures vary little throughout the year; the average daily temperature range of Jakarta is 26–30 °C (79–86 °F).
Indonesian cuisine varies by region and is based on Chinese, European, Middle Eastern, and Indian precedents.Rice is the main staple food and is served with side dishes of meat and vegetables. Spices (notably chili), coconut milk, fish and chicken are fundamental ingredients. Indonesian traditional music includes gamelan and keroncong. Dangdut is a popular contemporary genre of pop music that draws influence from Arabic, Indian, and Malay folk music. The Indonesian film industry's popularity peaked in the 1980s and dominated cinemas in Indonesia, although it declined significantly in the early 1990s. Between 2000 and 2005, the number of Indonesian films released each year has steadily increased.
