Java Island
Java (Indonesian: Jawa) is an island of Indonesia and the site of its capital city, Jakarta. Once the centre of powerful Hindu-Buddhist kingdoms, Islamic sultanates, and the core of the colonial Dutch East Indies, Java now plays a dominant role in the economic and political life of Indonesia. Home to a population of 130 million in 2006, it is the most populous island in the world, ahead of Honshū, the main island of Japan. Java is also one of the most densely populated regions on Earth.
Formed mostly as the result of volcanic events, Java is the 13th largest island in the world and the fifth largest island in Indonesia. A chain of volcanic mountains forms an east-west spine along the island. It has three main languages, though Javanese is dominant and is the native language of 60 million people in Indonesia, most of whom live on Java. Most residents are bilingual, with Indonesian as their second language. While the majority of Javanese are Muslim, Java has a diverse mixture of religious beliefs and cultures.
Etymology
The origins of the name 'Java' are not clear. One possibility is that an early traveller from India named the island after the jáwa-wut plant, which was said to be common in the island during the time, and that prior to Indianization the island had different names. There are other possible sources: the word jaú and its variations mean "beyond" or "distant". And, in Sanskrit yava means barley, a plant for which the island was famous. Another source states that the "Java" word is derived from a Proto-Austronesian root word, meaning 'home'.
Geography
Java lies between Sumatra to the west and Bali to the east. Borneo lies to the north and Christmas Island to the south. It is the world's 13th largest island.
Java is almost entirely of volcanic origin; it contains no fewer than thirty-eight mountains forming an east-west spine which have at one time or another been active volcanoes. The highest volcano in Java is Mount Semeru (3,676 m). The most active volcano in Java and also in Indonesia is Mount Merapi (2,968 m). See Volcanoes of Java. Further mountains and highlands help to split the interior into a series of relatively isolated regions suitable for wet-rice cultivation; the rice lands of Java are among the richest in the world. Java was the first place where Indonesian coffee was grown, starting in 1699. Today, Coffea arabica is grown on the Ijen Plateau by small-holders and larger plantations.
The area of Java is approximately 139,000 km2. The island's longest river is the 600 km long Bengawan Solo River. The river rises from its source in central Java at the Lawu volcano, then flows north and eastwards to its mouth in the Java Sea near the city of Surabaya. The island is administratively divided into four provinces (Banten, West Java, Central Java, and East Java), one special region (Yogyakarta), and one special capital district (Jakarta).
