East Kalimantan

East Kalimantan: Borneo’s Land of Rivers, Industry & Coastal Beauty

Geographic Profile

East Kalimantan occupies the eastern region of Indonesian Borneo, bordered by the Makassar Strait to the south and neighboring provinces to the west. Covering approximately 127,346 km², it includes a rugged coastline, vast river systems—most notably the Mahakam River—and offshore islands such as Derawan. The provincial capital is Samarinda, while Balikpapan stands as the main economic hub.

Population and Demography

With around 3.7 million residents as of mid‑2024, the province is ethnically diverse. Indigenous Dayak groups, including Kenyah and Kutai, form a significant proportion alongside a large migrant population of Javanese, Bugis, and Banjar. A notable Chinese Indonesian community is found in urban areas. Islam is the predominant religion, with Christian and indigenous faith communities also respected.

Natural Environment & Biodiversity

East Kalimantan’s landscape is defined by tropical lowlands, peat swamps, and mountain forests. The Mahakam River basin supports critical rainforests and ecosystems that harbor orangutans, proboscis monkeys, and diverse wildlife. Coral reefs, mangroves, and white-sand beaches around Derawan Island contribute to rich marine biodiversity.

Economy and Infrastructure

A major economic engine in the region, East Kalimantan thrives on oil, natural gas, coal mining, and palm oil plantations. Samarinda and Balikpapan host heavy industries and serve as logistical centers with major seaports and an international airport. The Trans-Kalimantan Highway and river transport remain vital links for remote communities.

Administration and Governance

The province is divided into several regencies and the cities of Samarinda, Balikpapan, Bontang, and East Samarinda. Governance is overseen by a governor-supported administration coordinating local development, disaster management, and environmental policy.

Culture and Society

Dayak traditions flourish, with rich heritage in longhouse life, weaving, carving, and traditional festivals. Coastal communities contribute fishing culture and Chinese Indonesian influences in trade and festival life, underscoring East Kalimantan’s multicultural tapestry.

Tourism and Conservation

Tourist attractions include the Derawan Archipelago with its diving, turtle sanctuaries, and marine luxury; the Mahakam River ecological landscape; and protected areas such as Wehea and Bukit Bangkirai rainforest reserves. Ecotourism, wildlife conservation, and cultural homestays are key growth areas amid rising awareness of sustainability.

Environmental Challenges

The province faces critical environmental issues, including deforestation, peatland fires, and marine degradation from mining and plantation development. Initiatives for sustainable forestry, river and coastal restoration, community conservation, and collaboration with NGOs and indigenous groups are gaining momentum.
