Tarakan
Tarakan is an island and co-extensively the sole city within the newly established Indonesian province of North Kalimantan. The island city is located in northern Borneo, midway along the coast of the province. The city boundaries are co-extensive with the island (including a couple of small islands off the coast of the Tarakan Barat District). Once a major oil-producing region during the colonial period, Tarakan had great strategic importance during the Pacific War and was among the first Japanese targets early in the conflict. It is the sole city within the newly established (in 2012) Indonesian province of North Kalimantan. According to Statistics Indonesia, the city had a population of 193,370 at the 2010 Census and 242,786 inhabitants at the 2020 Census; the official estimate as at mid 2022 was 248,972 (comprising 128,895 males and 120,077 females. Geography 
The city is located on Tarakan island (off the east coast of Kalimantan), which composed of  of land. 27.5% of the city is composed of podzol soil and 57.63% latosol soil. The city is located between  above sea level. History

Etymology 
According to legends, native Tidungs established their kingdom in Tarakan around 1076 CE. After moving their capital several times over the centuries, in 1571 CE they settled their kingdom on the eastern coast of Tarakan, apparently already under the influence of Islam. The name Tarakan comes from the Tidung language:  (meeting place) and  (to eat); thus Tarakan was originally a meeting place for sailors and traders to eat, rest and trade their catch in the Tidung area. Petroleum 

Dutch explorers noted oil seepages in 1863. In 1905, an oil concession was granted to Koninklijke Nederlandsche Petroleum Maatschappij' a predecessor to Royal Dutch Shell. One year later oil production began with a yield of over 57,928 barrels of oil per year. Production continued to increase and in the 1920s Tarakan yielded over five million barrels a year, a third of the total oil production in the whole of the Dutch East Indies. The oil produced here had a paraffin base instead of the usual asphalt base. Tarakan oil fields produced a light, sour crude oil with an unusually low pour point. By 1940, the island had an oil refinery with four petroleum loading piers, and was one of the five largest petroleum processing centers in the East Indies. World War II

Japanese oil fields in Sakhalin and Formosa provided only about ten percent of the petroleum needed to sustain Japanese industry. Reserves of California crude oil at Japanese refineries would have been exhausted in less than two years at the rate of consumption when the United States terminated exports to Japan on 26 July 1941. Japan initiated hostilities against the United States and the United Kingdom four months later in preparation for seizing alternative sources of petroleum in the East Indies. Japan declared war on the Netherlands East Indies on 10 January 1942; and Japanese troops landed on Tarakan the following day. Dutch forces had declared war on Japan a month earlier, and sabotaged the oil field and refinery prior to surrender. Japan had captured the Miri oil field in December, and captured oil fields and refineries at Balikpapan in January, Sumatra in February, and Java in March. Oil technicians accompanied the invading troops to maintain production at captured facilities. A team of one thousand additional petroleum engineers and technicians sailed from Japan aboard the Taiyo Maru, but nearly 800 drowned when the ship was sunk southwest of Kyushu by the USS Grenadier on 8 May 1942. Despite this loss, Tarakan crude oil (mixed with lesser quantities of Manchurian oil shale distillates) became the primary feedstock for Japanese diesel fuel in 1942, while reserve supplies of California crude oil remained the primary feedstock for Japanese gasoline and residual fuels until 1943. Tarakan became a Japanese strategic air base from which further attacks could be launched following the Dutch surrender. Tarakan's inhabitants suffered under Japan's occupation. The large number of Japanese troops stationed on the island led to food shortages and many civilians suffered from malnutrition. During the occupation, the Japanese transported some 600 labourers to Tarakan from Java. The Japanese also forced an estimated 300 Javanese women to work as "comfort women". Tarakan oil field production reached 350,000 barrels per month by early 1944, but Japan no longer had enough oil tankers to transport this volume to Japanese refineries. Without adequate supplies of refined residual fuel oil for the Battle of the Philippine Sea, Japanese aircraft carriers refueled with unrefined Tarakan crude oil in June 1944. The undesalted crude oil damaged boiler tubes, and the unremoved naphtha fraction volatilized to form explosive atmospheres contributing to the loss of the aircraft carriers Taihō, Shōkaku, and Hiyō. The last Japanese tanker left Tarakan in July 1944; Allied bombing raids damaged the oil field facilities later that year; and the veteran Australian 26th Brigade Group ended Japanese occupation with the second Battle of Tarakan from 1 May–21 June 1945. Independence Era
Following the Indonesian revolution in the late 1940s, Tarakan became part of the new republic. It was administered as a district following a Presidential Decree Number 22, 1963. In 1981, Tarakan was granted a city charter, at that time one of four cities in East Kalimantan, along with Samarinda, Balikpapan and Bontang in accordance with Government Law Number 47, 1981. The city witnessed the Tarakan riot in 2010 following a clash between Buginese migrants from neighboring Sulawesi island and the Tidung people. The two groups later agreed to a peace deal, mediated by local police and the governor of then-East Kalimantan, Awang Faroek Ishak. After North Kalimantan was established as a province in 2012, Tarakan became the sole city within the new province. In 2015, the city witnessed another riot, this time related to the 2015 North Kalimantan gubernatorial election between the candidates' supporters. Demographics 
Tarakan had a population of 193,370 at the 2010 Census, but the 2020 Census this had grown to 242,786, and the official estimate as at mid 2022 was 248,972.

Population growth averaged 2.23% per year in the decade 2010-2020. The city population has increased rapidly which is thought to be caused by high urbanization rate with people moving in from neighbouring regions.
