5 Largest Islands in Indonesia and Their Uniqueness

Indonesia consists of five major islands, each with unique geographical, cultural, and economic characteristics. Understanding the characteristics of each island is an important foundation in studying Indonesia's geography.

Papua Island: Indonesia's Giant

With an area of about 785,753 km², Papua Island is Indonesia's largest and the world's second largest after Greenland. This island stores extraordinary biodiversity, including various species found only here.

The central mountains of Papua create a backbone that divides the island from northwest to southeast. Puncak Jaya Wijaya at 4,884 meters is Indonesia's highest point. The ice at the mountain peak is one of the few tropical glaciers in the world.

The people of Papua have extraordinary cultural diversity. Asmat Tribe, Dani Tribe, and Korowai Tribe are among hundreds of tribes inhabiting this island. Each tribe has unique language, traditions, and ways of life.

Papua's economy is dominated by mining and fisheries sectors. Freeport Indonesia operates in the Grasberg mine which is one of the world's largest gold and copper mines. Papua's waters are also famous for their tuna fish wealth.

Kalimantan Island: Tropical Rainforest

Kalimantan occupies the second position with an area of 544,852 km². This island is famous for its tropical rainforest which is one of the oldest in the world. Biodiversity here is extraordinary with thousands of plant and animal species.

Borneo's lowlands are filled with swamp forests and kerangas forests. Orangutans, tigers (in the north), and various other endemic species inhabit these forests. However, deforestation threatens their habitat.

Kalimantan's people are very complex. Dayak Tribe with their traditions, Banjar Tribe in South Kalimantan, and migrants from various regions create a rich cultural mosaic. The equator divides this island through Pontianak.

Kalimantan's economy is supported by coal, oil, and timber mining. Oil palm plantations also dominate the economic landscape, although controversial due to their environmental impact.

Sumatra Island: Resource-Rich Island

Sumatra is the third largest island with an area of 473,481 km². This island is famous for its abundant natural wealth, from coal, oil, to agricultural products.

Bukit Barisan stretches along the west side of the island, creating a natural barrier between the west coastal plains and the eastern plains. Active volcanoes such as Mount Kerinci and Mount Sinabung inhabit this mountain belt.

The eastern lowlands of Sumatra are the national food barn. Productive rice fields produce rice for all of Indonesia. The plantation industry is also very developed with rubber, oil palm, and tea as main commodities.

Sumatra's people are very diverse from north to south. Acehnese in the north, Batak with their traditional music and dance, Malay in Riau and Jambi, to Minangkabau with their unique matrilineal system.

Sulawesi Island: Unique K Shape

Sulawesi has a very unique shape with four peninsulas resembling the letter K. With an area of 180,681 km², this island stores extraordinary geological and biological diversity.

Sulawesi's geological formation is very complex because it is the meeting of three tectonic plates. This creates dramatic relief with high mountains and deep valleys. Lake Towuti and Lake Matano are ancient lakes storing endemic species.

Anoa, babirusa, and tarsius are some of Sulawesi's iconic species not found elsewhere. Underwater biodiversity in Wakatobi and Bunaken is also world-class.

Sulawesi's people are very diverse. Bugis Tribe as sailors and traders, Toraja with their famous funeral ceremonies, and Minahasa with their distinctive cuisine create a rich cultural mosaic.

Java Island: Most Densely Populated Island

Java is the fifth largest but most densely populated island. With an area of about 128,297 km², this island is inhabited by more than 150 million people. This density creates unique challenges and opportunities.

Java lies on the Pacific Ring of Fire with dozens of active volcanoes. Mount Merapi, Semeru, and Bromo are some of the most famous. This volcanism creates fertile soil for agriculture.

Rice is Java's main commodity. The neatly arranged rice fields create an iconic landscape. Vegetables and tea from the highlands are also famous for their high quality.

The Javanese are the largest in Indonesia. Javanese culture with wayang, dance, and gamelan is very influential in shaping national identity. Java is also the center of modern Indonesia's government and economy.

Conclusion

Indonesia's five major islands each have uniqueness that distinguishes them. From Kalimantan's rainforests to Papua's mountains, from Sumatra's lowlands to Java's volcanic areas, each island stores extraordinary wealth. This diversity is Indonesia's strength that must be maintained and developed.
