Kotabaru Regency is one of the eleven regencies in the Indonesian province of South Kalimantan. It consists of two parts; the smaller but more populated part comprises Laut Island ("Sea Island"), the largest island off the coast of Kalimantan (Indonesian Borneo), together with the smaller Sebuku Island off Laut Island's east coast and even smaller islands nearby; the larger but less populated part consists of districts on the mainland of Kalimantan. The regency has an area of 9,442.46 km2, and had a population of 290,142 at the 2010 Census[3] and 325,622 at the 2020 Census.[4] The official estimate as at mid 2021 was 329,483.[5] The regency seat is located at the large town of Kotabaru at the northern tip of Laut Island.

It has the second largest GRDP in the province after city of Banjarmasin, mainly due to its coal industry. It is also the largest regency by land area in the province.[6]



The regency got its name from Kotabaru town, which is the administrative center of the regency. The town was previously a village that grew because of coal mining around 1873 and 1881. The coal mines were mostly owned by nobles of small kingdoms in the islands such as Pagatan and Kusan. The village grows into a town and called Kotta Baroe, which literally means "new town". Throughout 20th century until today, the region became commonly known as Kotabaru.[7]

Early history

In the region of what's now the regency, there were several petty kingdoms and sultanates which were closely tied to Sultanate of Banjar. It is estimated that these kingdoms came into existence around after 1786, following foundation Kusan and Pagatan Kingdom in the island of Laut by Prince Amir from Kingdom of Kayutangi [8] Both kingdoms were later on became subject to Kayutangi and obliged to pay tributaries. On 1840, Kusan and Pagatan entered a personal union after fourth king of Kusan, Jaya Sumitra, gave the kingdom to Arung Abdul Karim who was the king of Pagatan and assuming control over the entire island of Laut. On 1881, son of Jaya Sumitra, Prince Husin Kusuma took the title of fourth king of Laut Island. Husin Kusuma soon died in 1900 when taking a hajj and was succeeded by Prince Aminullah who would become the last king of Laut.[8][9]

Colonial era

In 1905, Dutch East Indies government declared the end of small kingdoms existence in the island following the defeat of Banjar Sultanate after Banjarmasin War. The region was then directly ruled by colonial government instead of getting through local kings and officials.[8][9] In 1942, the region was occupied by Empire of Japan following World War II.

In the aftermath of the war and Indonesian National Revolution, returning Dutch proposed a puppet state of Southeast Borneo Federation in the region. This was opposed and conflicts erupted in the region, known as Kalimantan Physical Revolution. On 1 September 1945, Committee for Assisting Republic Indonesian (BPRI, Badan Pembantu Republik Indonesia) was formed in town of Pagatan and spread its branch to Laut island. On 6 December 1945, students and Republican militia declared a motion declaring the region part of Indonesian Republic. On 7 February 1946, a battle broke out between Republican militia and Dutch soldiers that tried to land in beach of Laut island around village of Kampung Baru.[10][11]

Following the return of Dutch authority, several demonstrations were held in town of Pagatan and Kotabaru and Indonesian flag was hoisted in a wet market in Pagatan in October 1949.[6] Southeast Borneo Federation were eventually dissolved by its own parliament and joined Indonesian Republic following transfer of sovereignty.[9][12]

After independence

The regency on its own came into existence in 1953, which made of administrative divisions in Laut Island, Southern Tanah Bumbu, Northern Tanah Bumbu, and Pasir Residency. However, Pasir Residency was cut off from the regency after division of Kalimantan into several provinces.[6] Following fall of Suharto and rapid decentralization it follows, there has been demand from mainland districts to seceded from the regency and form their own.[13] Tanah Bumbu was split off from the rest of Kotabaru Regency on 25 February 2003 and made into a separate regency. This process is caused by dissatisfaction from the regency government on Laut Island where the island is more developed than the mainland Kalimantan parts.[13][14] This is however as of 2021 has not been materialized.[13]



Kotabaru has a tropical rainforest climate (Af) with heavy rainfall year-round.
