East Kalimantan in the context of "Capital City of Nusantara"

Lubang Jeriji Saléh is a limestone cave complex in Indonesia, located within the Sangkulirang-Mangkalihat Karst in the remote jungle of the Bengalon district of East Kutai Regency, East Kalimantan province, on Borneo island. In 2018, a team of researchers announced the discovery of what was then believed to be the oldest known work of figurative art in the world among the cave paintings, dating back 40,000 years. However, the same team has since found and dated an elaborate therianthrope rock art panel in the Leang Bulu' Sipong 4 cave in Sulawesi's Maros-Pangkep karst to approximately 44,000 years ago.

West Kalimantan (Indonesian: Kalimantan Barat) is a province of Indonesia. It is one of five Indonesian provinces comprising Kalimantan, the Indonesian part of the island of Borneo. Its capital and largest city is Pontianak. It is bordered by East Kalimantan and Central Kalimantan to the east, the Malaysian state of Sarawak to the north, and the Bangka Belitung Islands to the west and the Java Sea to the south. The province has an area of 147,037 km, and had a population of 4,395,983 at the 2010 Census and 5,414,390 at the 2020 Census; the official estimate as at mid 2023 was 5,623,328 (comprising 2,887,209 males and 2,736,119 females), and was projected to rise to 5,695,500 at mid 2024. Ethnic groups include the Dayak, Malay, Chinese, Javanese, Bugis, and Madurese. The borders of West Kalimantan roughly trace the mountain ranges surrounding the vast watershed of the Kapuas River, which drains most of the province. The province shares land borders with Central Kalimantan to the southeast, East Kalimantan to the east, and the Malaysian state of Sarawak to the north.

West Kalimantan is nicknamed "The Province of a Thousand Rivers". The nickname references the geography of the province, which features hundreds of rivers of varying size, most of which are navigable. Several major rivers are still the main route for freight to the hinterland, despite road infrastructure now reaching most districts.

Malays (Malay: Orang Melayu, Jawi script: اورڠ ملايو‎) are an Austronesian ethnoreligious group native to the Malay Peninsula, eastern Sumatra, coastal Borneo, and the smaller islands that lie between these locations known as Riau Archipelago. These locations are today part of the countries of Malaysia, Indonesia (eastern and southern Sumatra, Bangka Belitung Islands, West Kalimantan, Riau Islands, and the coast of East Kalimantan), the southern part of Thailand (Pattani, Satun, Songkhla, Trang, Yala, and Narathiwat), Singapore, and Brunei Darussalam.

There is considerable linguistic, cultural, artistic and social diversity among the many Malay subgroups, mainly due to hundreds of years of immigration and assimilation of various regional ethnicity and tribes within Maritime Southeast Asia. Historically, the Malay population is descended primarily from the earlier Malayic-speaking Austronesians and Austroasiatic tribes who founded several ancient maritime trading states and kingdoms, notably Brunei, Kedah, Langkasuka, Gangga Negara, Chi Tu, Nakhon Si Thammarat, Pahang, Melayu and Srivijaya.

Kalimantan (Indonesian pronunciation: [kaliˈmantan]) is the Indonesian portion of the island of Borneo. It constitutes 73% of the island's area, and consists of the provinces of Central Kalimantan, East Kalimantan, North Kalimantan, South Kalimantan, and West Kalimantan. The non-Indonesian parts of Borneo are Brunei and East Malaysia. In Indonesia the whole island of Borneo is also called "Kalimantan".

In 2019, President of Indonesia Joko Widodo proposed that Indonesia's capital be moved to Kalimantan. The People's Consultative Assembly approved the Law on State Capital in January 2022. The future capital, Nusantara, is a planned city that will be carved out of East Kalimantan. A government official said construction is expected to be fully complete by 2045, but the unfinished capital officially celebrated Indonesian Independence Day for the first time and it was scheduled to be inaugurated as the capital city on 17 August 2024, but the move did not take place due to delays of construction.

Banjarese (/ˈbændʒəˌriːz/ BAN-juh-reez; Basa Banjar, Jaku Banjar, Jawi script: باس بنجر‎ IPA: [basa bandʒar], [dʒaku bandʒar]) or simply Banjar, is an Austronesian language of the Malayic branch predominantly spoken by the Banjarese—an indigenous ethnic group native to Banjar regions— in the southeastern Kalimantan of Indonesia. The Banjarese language is the de facto lingua franca for various indigenous community especially in South Kalimantan, as well as Central Kalimantan (notably in Seruyan Regency and Sukamara Regency) and East Kalimantan in general.

Banjarese also has significant population in other provinces in Indonesia, especially in Sumatra (Riau and North Sumatra) even some regencies in Riau has a Banjarese majority population like in Indragiri Hilir Regency.

In May 2015, it has been nominated for inclusion in the UNESCO World Heritage Site list. The cave paintings within the caves in the Sangkulirang-Mangkalihat karsts was suggested to be a Geopark in April 2017. The paintings were researched extensively by Indonesia's Heritage Preservation Hall (BPCB) for its preservation. The closest major airport to the geopark is Samarinda International Airport.

Amputation is the removal of a limb or other body part by trauma, medical illness, or surgery. As a surgical measure, it is used to control pain or a disease process in the affected limb, such as malignancy or gangrene. In some cases, it is carried out on individuals as a preventive surgery for such problems. A special case is that of congenital amputation, a congenital disorder, where fetal limbs have been cut off by constrictive bands. In some countries, judicial amputation is currently used to punish people who commit crimes. Amputation has also been used as a tactic in war and acts of terrorism; it may also occur as a war injury. In some cultures and religions, minor amputations or mutilations are considered a ritual accomplishment. When done by a person, the person executing the amputation is an amputator. The oldest evidence of this practice comes from a skeleton found buried in Liang Tebo cave, East Kalimantan, Indonesian Borneo dating back to at least 31,000 years ago, where it was done when the amputee was a young child. A prosthesis or a bioelectric replantation restores sensation of the amputated limb.
