Culture

Indonesia has around 300 ethnic groups, each with cultural identities developed over centuries, and influenced by Indian, Arabic, Chinese, and European sources. Traditional Javanese and Balinese dances, for example, contain aspects of Hindu culture and mythology, as do wayang kulit (shadow puppet) performances. Textiles such as batik, ikat and songket are created across Indonesia in styles that vary by region. The most dominant influences on Indonesian architecture have traditionally been Indian; however, Chinese, Arab, and European architectural influences have been significant.
Sports in Indonesia are generally male-orientated and spectator sports are often associated with illegal gambling. The most popular sports are badminton and football. Indonesian players have won the Thomas Cup (the world team championship of men's badminton) thirteen of the twenty-six times that it has been held since 1949, as well as numerous Olympic medals since the sport gained full Olympic status in 1992. Its women have won the Uber Cup, the female equivalent of the Thomas Cup, twice, in 1994 and 1996. Liga Indonesia is the country's premier football club league. Traditional sports include sepak takraw, and bull racing in Madura. In areas with a history of tribal warfare, mock fighting contests are held, such as, caci in Flores, and pasola in Sumba. Pencak Silat is an Indonesian martial art.

Economy

Indonesia has a mixed economy in which both the private sector and government play significant roles. The country is the largest economy in Southeast Asia and a member of the G-20 major economies. Indonesia's estimated gross domestic product (nominal), as of 2009 was US$539.7 billion with estimated nominal per capita GDP was US$2,329, and per capita GDP PPP was US$4,157 (international dollars). The industry sector is the economy's largest and accounts for 47.6% of GDP (2009). This is followed by services (37.1%) and agriculture (15.3%). However, as of 2005, agriculture remained employing more people than other sectors, accounting for 44.3% of the 95 million-strong workforce. This is followed by the services sector (36.9%) and industry (18.8%). Major industries include petroleum and natural gas, textiles, apparel, and mining. Major agricultural products include palm oil, rice, tea, coffee, spices, and rubber. Tourism in Indonesia, despite less contributing to the GDP, has performed very well for these last five years. The international tourist arrival to the country has also grown steadily, and reached a new record with 7 million foreign visitors by 2010.
Indonesia's main export markets (2005) are Japan (22.3%), the United States (13.9%), China (9.1%), and Singapore (8.9%). The major suppliers of imports to Indonesia are Japan (18.0%), China (16.1%), and Singapore (12.8%). In 2005, Indonesia ran a trade surplus with export revenues of US$83.64 billion and import expenditure of US$62.02 billion. The country has extensive natural resources, including crude oil, natural gas, tin, copper, and gold. Indonesia's major imports include machinery and equipment, chemicals, fuels, and foodstuffs.

Indonesia lies between latitudes 11°S and 6°N, and longitudes 95°E and 141°E. It consists of 17,508 islands, about 6,000 of which are inhabited. These are scattered over both sides of the equator. The largest are Java, Sumatra, Borneo (shared with Brunei and Malaysia), New Guinea (shared with Papua New Guinea), and Sulawesi. Indonesia shares land borders with Malaysia on Borneo, Papua New Guinea on the island of New Guinea, and East Timor on the island of Timor. Indonesia shares maritime borders across narrow straits with Singapore, Malaysia, and the Philippines to the north, and with Australia to the south. 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). At 4,884 metres (16,024 ft), Puncak Jaya in Papua is Indonesia's highest peak, and Lake Toba in Sumatra its largest lake, with an area of 1,145 square kilometers (442 sq mi). The country's largest rivers are in Kalimantan, and include the Mahakam and Barito; such rivers are communication and transport links between the island's river settlements.

The name Indonesia derives from the Latin Indus, and the Greek nesos, meaning "island". The name dates to the 18th century, far predating the formation of independent Indonesia. In 1850, George Windsor Earl, an English ethnologist, proposed the terms Indunesians — and, his preference, Malayunesians — for the inhabitants of the "Indian Archipelago or Malayan Archipelago". In the same publication, a student of Earl's, James Richardson Logan, used Indonesia as a synonym for Indian Archipelago. However, Dutch academics writing in East Indies publications were reluctant to use Indonesia. Instead, they used the terms Malay Archipelago (Maleische Archipel); the Netherlands East Indies (Nederlandsch Oost Indië), popularly Indië; the East (de Oost); and even Insulinde.
From 1900, the name Indonesia became more common in academic circles outside the Netherlands, and Indonesian nationalist groups adopted it for political expression. Adolf Bastian, of the University of Berlin, popularized the name through his book Indonesien oder die Inseln des Malayischen Archipels, 1884–1894. The first Indonesian scholar to use the name was Suwardi Suryaningrat (Ki Hajar Dewantara), when he established a press bureau in the Netherlands with the name Indonesisch Pers-bureau in 1913.

Indonesia

Indonesia (ⁱ /ˌɪndəˈniːʒə/ or /ˌɪndoʊˈniːziə/), officially the Republic of Indonesia (Indonesian: Republik Indonesia), is a country in Southeast Asia and Oceania. Indonesia comprises 17,508 islands. With a population of around 238 million people, it is the world's fourth most populous country, and has the world's largest population of Muslims. Indonesia is a republic, with an elected legislature and president. The nation's capital city is Jakarta. The country shares land borders with Papua New Guinea, East Timor, and Malaysia. Other neighboring countries include Singapore, Philippines, Australia, and the Indian territory of the Andaman and Nicobar Islands. Indonesia is a founding member of ASEAN and a member of the G-20 major economies. The Indonesian economy is the world's eighteenth largest economy by nominal GDP and fifteenth largest by purchasing power parity.
The Indonesian archipelago has been an important trade region since at least the 7th century, when Srivijaya and then later Majapahit traded with China and India. Local rulers gradually absorbed foreign cultural, religious and political models from the early centuries CE, and Hindu and Buddhist kingdoms flourished. Indonesian history has been influenced by foreign powers drawn to its natural resources. Muslim traders brought Islam, and European powers fought one another to monopolize trade in the Spice Islands of Maluku during the Age of Discovery. Following three and a half centuries of Dutch colonialism, Indonesia secured its independence after World War II. Indonesia's history has since been turbulent, with challenges posed by natural disasters, corruption, separatism, a democratization process, and periods of rapid economic change. The current nation of Indonesia is a unitary presidential republic consisting of thirty three provinces.
Across its many islands, Indonesia consists of distinct ethnic, linguistic, and religious groups. The Javanese are the largest—and the politically dominant—ethnic group. Indonesia has developed a shared identity defined by a national language, ethnic diversity, religious pluralism within a majority Muslim population, and a history of colonialism including rebellion against it. Indonesia's national motto, "Bhinneka Tunggal Ika" ("Unity in Diversity" literally, "many, yet one"), articulates the diversity that shapes the country. Despite its large population and densely populated regions, Indonesia has vast areas of wilderness that support the world's second highest level of biodiversity. The country is richly endowed with natural resources, yet poverty remains widespread in contemporary Indonesia.
