Balikpapan is the city with the largest economy in Kalimantan with an estimated 2016 GDP at Rp 73.18 trillion. The city is served by Sultan Aji Muhammad Sulaiman Sepinggan Airport . Port of Semayang was the second busiest seaport in East Kalimantan, after that in Samarinda . With

278-648: A Royal Air Force officer, Air Marshal Sir Donald Hardman , was brought out to Australia to become Chief of the Air Staff. He reorganised the RAAF into three commands: Home Command , Maintenance Command , and Training Command . Five years later, Home Command was renamed Operational Command , and Training Command and Maintenance Command were amalgamated to form Support Command . In the Malayan Emergency , from 1950 to 1960, six Avro Lincolns from No. 1 Squadron RAAF and

417-1051: A bombing raid. The wreckage of the aircraft was recovered in April 2009, and the remains of the crew were found in late July 2009. The other was shot down by a surface-to-air missile , although both crew were rescued. They dropped 76,389 bombs and were credited with 786 enemy personnel confirmed killed and a further 3,390 estimated killed, 8,637 structures, 15,568 bunkers, 1,267 sampans and 74 bridges destroyed. RAAF transport aircraft also supported anti-communist ground forces. The UH-1 helicopters were used in many roles including medical evacuation and close air support. RAAF casualties in Vietnam included six killed in action, eight non-battle fatalities, 30 wounded in action and 30 injured. A small number of RAAF pilots also served in United States Air Force units, flying F-4 Phantom fighter-bombers or serving as forward air controllers. In September 1975,

556-573: A central area containing buildings with special economic, political, and religious significance. Archaeologists refer to this area by the Greek term temenos or if fortified as a citadel . These spaces historically reflect and amplify the city's centrality and importance to its wider sphere of influence . Today cities have a city center or downtown , sometimes coincident with a central business district . Cities typically have public spaces where anyone can go. These include privately owned spaces open to

695-665: A central authority. The term can also refer either to the physical streets and buildings of the city or to the collection of people who dwell there and can be used in a general sense to mean urban rather than rural territory . National censuses use a variety of definitions – invoking factors such as population , population density , number of dwellings , economic function, and infrastructure – to classify populations as urban. Typical working definitions for small-city populations start at around 100,000 people. Common population definitions for an urban area (city or town) range between 1,500 and 50,000 people, with most U.S. states using

834-461: A central point. This form could evolve from successive growth over a long time, with concentric traces of town walls and citadels marking older city boundaries. In more recent history, such forms were supplemented by ring roads moving traffic around the outskirts of a town. Dutch cities such as Amsterdam and Haarlem are structured as a central square surrounded by concentric canals marking every expansion. In cities such as Moscow , this pattern

973-539: A combination of these. Societies that live in cities are often called civilizations . The degree of urbanization is a modern metric to help define what comprises a city: "a population of at least 50,000 inhabitants in contiguous dense grid cells (>1,500 inhabitants per square kilometer)". This metric was "devised over years by the European Commission , OECD , World Bank and others, and endorsed in March [2021] by

1112-604: A continuous urban landscape called urban agglomeration , conurbation , or megalopolis (exemplified by the BosWash corridor of the Northeastern United States .) The emergence of cities from proto-urban settlements , such as Çatalhöyük , is a non-linear development that demonstrates the varied experiences of early urbanization . The cities of Jericho , Aleppo , Byblos , Faiyum , Yerevan , Athens , Matera , Damascus , and Argos are among those laying claim to

1251-430: A distinctive elite social class, but it should indeed be considered a city based on a functional redefinition of urban development. In particular, Jenné-Jeno featured settlement mounds arranged according to a horizontal, rather than vertical, power hierarchy, and served as a center of specialized production and exhibited functional interdependence with the surrounding hinterland. More recently, scholars have concluded that

1390-553: A fisherman. An alternative story is that, at the time of the Kutai sultanate, Sultan Muhammad Idris sent 1000 planks to aid the Paser Kingdom to build a new palace. The planks were shipped from Kutai to Paser along the Borneo shoreline by roping all the planks together. 10 out of the 1000 planks that were originally shipped resurfaced in a place currently called Balikpapan. On 10 February 1897,

1529-628: A fishing village built by Buginese people in the 19th century. The first oil drilling began in Balikpapan on 10 February 1897, which was later set as the anniversary of the city. In 1899, the Dutch East Indies colonial administration granted a township status to Balikpapan. In 1907, Bataafsche Petroleum Maatschappij (BPM) made the city as its headquarters and imported skilled laborers, engineers, and managers from overseas. Subsequently, numerous multi-national companies came to Balikpapan to invest in

The urban-type settlement extends far beyond the traditional boundaries of the city proper in a form of development sometimes described critically as urban sprawl . Decentralization and dispersal of city functions (commercial, industrial, residential, cultural, political) has transformed the very meaning of

1946-777: A group of 44 civilians, including armed supporters of the Timorese Democratic Union (UDT), commandeered an RAAF Caribou, A4-140 , on the ground at Baucau Airport in the then Portuguese Timor , which was in the middle of a civil war. The Caribou had landed at Baucau on a humanitarian mission for the International Committee of the Red Cross . The civilians demanded that the RAAF crew members fly them to Darwin Airport (also RAAF Base Darwin ) in Australia, which they did. After

2085-507: A key role in both the economy and government. Late antique cities in the East were also undergoing intense transformations, with increased political participation of the crowds and demographical fluctuations. Christian communities and their doctrinal differences increasingly shaped the urban fabric. The locus of power shifted to Constantinople and to the ascendant Islamic civilization with its major cities Baghdad , Cairo , and Córdoba . From

2224-520: A minimum between 1,500 and 5,000 inhabitants. Some jurisdictions set no such minima. In the United Kingdom , city status is awarded by the Crown and then remains permanent. (Historically, the qualifying factor was the presence of a cathedral , resulting in some very small cities such as Wells , with a population of 12,000 as of 2018 , and St Davids , with a population of 1,841 as of 2011 .) According to

2363-458: A population of 688,318 according to the 2020 census , and an official estimate of 738,532 as at mid 2023 (comprising 277,458 males and 361,074 females), Balikpapan is the second most populous city in East Kalimantan , after Samarinda . Balikpapan has been consistently ranked as the most liveable city in Indonesia. However, in 2022, Balikpapan conceded this to Samarinda . Balikpapan was originally

2502-688: A privileged elite among towns having won self-governance from their local lord or having been granted self-governance by the emperor and being placed under his immediate protection. By 1480, these cities, as far as still part of the empire, became part of the Imperial Estates governing the empire with the emperor through the Imperial Diet . By the 13th and 14th centuries, some cities become powerful states, taking surrounding areas under their control or establishing extensive maritime empires. In Italy, medieval communes developed into city-states including

2641-495: A rule cannot produce their own food and therefore must develop some relationship with a hinterland that sustains them. Only in special cases such as mining towns which play a vital role in long-distance trade, are cities disconnected from the countryside which feeds them. Thus, centrality within a productive region influences siting, as economic forces would, in theory, favor the creation of marketplaces in optimal mutually reachable locations. The vast majority of cities have

2780-548: A single E-7A Wedgetail . This aircraft, and the associated 100 personnel - mainly from 2 Squadron , would operate from Ramstein Air Base for a six month deployment under Operation Kudu. The stated objective of the deployment was to "help ensure that vital support flowing to Ukraine by the international community is protected." Trainer aircraft As of June 2018, the RAAF had 14,313 permanent full-time personnel and 5,499 part-time active reserve personnel. The RAAF established

2919-618: A small part of the operation, the RAAF contribution was significant, flying 2,062 sorties and carrying 7,030 tons of freight and 6,964 passengers. In the Korean War , from 1950 to 1953, North American Mustangs from No. 77 Squadron RAAF , stationed in Japan with the British Commonwealth Occupation Force , were among the first United Nations aircraft to be deployed, in ground support, combat air patrol, and escort missions.

Building of roads, wharves, warehouses, offices, barracks, and bungalows started when the Dutch oil company Bataafsche Petroleum Maatschappij (BPM) arrived in the area. On 24 January 1942, a Japanese invasion convoy arrived at Balikpapan and was attacked by four United States Navy destroyers that sank three Japanese transports. The Japanese army landed and met with no opposition by

3197-458: A spectrum of operations such as air superiority, precision strikes, intelligence, surveillance, and reconnaissance, air mobility, space surveillance , and humanitarian support. The RAAF has 252 aircraft, of which 84 are combat aircraft. The RAAF traces its history back to the 1911 Imperial Conference that was held in London, where it was decided aviation should be developed within the armed forces of

3336-549: A super-wealthy elite living in gated communities and large masses of people living in substandard housing with inadequate infrastructure and otherwise poor conditions. Cities around the world have expanded physically as they grow in population, with increases in their surface extent, with the creation of high-rise buildings for residential and commercial use, and with development underground. Urbanization can create rapid demand for water resources management , as formerly good sources of freshwater become overused and polluted, and

3475-423: A temple. A minority viewpoint considers that cities may have arisen without agriculture, due to alternative means of subsistence (fishing), to use as communal seasonal shelters, to their value as bases for defensive and offensive military organization, or to their inherent economic function. Cities played a crucial role in the establishment of political power over an area, and ancient leaders such as Alexander

3614-586: A total of 216,900 men and women served in the RAAF, of whom 10,562 were killed in action; a total of 76 squadrons were formed. With over 152,000 personnel operating nearly 6,000 aircraft it was the world's fourth-largest air force. During the Berlin Airlift , in 1948–49, the RAAF Squadron Berlin Air Lift aided the international effort to fly in supplies to the stricken city; two RAF Avro York aircraft were also crewed by RAAF personnel. Although

These sites appear planned in a highly regimented and stratified fashion, with a minimalistic grid of rooms for the workers and increasingly more elaborate housing available for higher classes. In Mesopotamia, the civilization of Sumer , followed by Assyria and Babylon , gave rise to numerous cities, governed by kings and fostered multiple languages written in cuneiform . The Phoenician trading empire, flourishing around

Balikpapan's toponym ( balik = "behind" and papan = "plank") is from a folk story in which a local king threw his newborn daughter into the sea to protect her from his enemies. The baby was tied beneath some planks that were discovered by

4170-441: Is no real dry season in Balikpapan. The city sees an average of 2,400 millimeters (94 inches) of rain per year. Balikpapan generally shows little variation in weather throughout the course of the year.

During the fighting for Rabaul in early 1942, No. 24 Squadron RAAF fought a brief, but ultimately futile defence as the Japanese advanced south towards Australia. The devastating air raids on Darwin on 19 February 1942 increased concerns about the direct threat facing Australia. In response, some RAAF squadrons were transferred from

This initially consisted of the Central Flying School at Point Cook, Victoria , opening on 22 October 1912. By 1914 the corps was known as the "Australian Flying Corps". Soon after the outbreak of war in 1914, the Australian Flying Corps sent aircraft to assist in capturing German colonies in what

6116-695: The Pacific War —and the rapid advance of Japanese forces—threatened the Australian mainland for the first time in its history. The RAAF was quite unprepared for the emergency, and initially had negligible forces available for service in the Pacific. In 1941 and early 1942, many RAAF airmen, including Nos. 1, 8, 21 and 453 Squadrons , saw action with the RAF Far East Command in the Malayan , Singapore and Dutch East Indies campaigns . Equipped with aircraft such as

The policy was heavily criticized for uncontrolled environmental damage and corrupt bureaucrats and politicians, but it significantly boosted urban development in resource-rich cities. In the 1970s Balikpapan experienced 7% population growth annually, while exports of timber and petroleum increased dramatically. The indigenous tribe of Balikpapan

6533-931: The United Nations ... largely for the purpose of international statistical comparison". The word city and the related civilization come from the Latin root civitas , originally meaning 'citizenship' or 'community member' and eventually coming to correspond with urbs , meaning 'city' in a more physical sense. The Roman civitas was closely linked with the Greek polis —another common root appearing in English words such as metropolis . In toponymic terminology, names of individual cities and towns are called astionyms (from Ancient Greek ἄστυ 'city or town' and ὄνομα 'name'). Urban geography deals both with cities in their larger context and with their internal structure. Cities are estimated to cover about 3% of

6672-501: The Uruk period . In the fourth and third millennium BC , complex civilizations flourished in the river valleys of Mesopotamia , India , China , and Egypt . Excavations in these areas have found the ruins of cities geared variously towards trade, politics, or religion.

By late 1945, the RAAF had received or ordered about 500 P-51 Mustangs , for fighter/ground attack purposes. The Commonwealth Aircraft Corporation initially assembled US-made Mustangs, but later manufactured most of those used. By mid-1945,

9869-422: The Caribou arrived there, the Australian government detained the civilians for a short period, and then granted refugee visas to all of them. The Guardian later described A4-140 as "the only RAAF plane ever hijacked", and the incident as "one of the more remarkable stories in Australia's military and immigration history". Military airlifts were conducted for a number of purposes in subsequent decades, such as

10008-466: The Dutch troops, which had been ordered to evacuate after destroying the oil installations. In response to this, the Japanese massacred 78 Dutch POWs and civilians . Royal Australian Air Force (RAAF) intelligence determined that half of all lubricating oils used by the Japanese military and 60 percent of all their aviation fuel came from refineries in Balikpapan, and it was therefore an extremely important target. The American 380th Bombardment Group under

10147-539: The Finance Department, Angkasa Pura 1, the Port of Semayang, and several others also attract many people to work in this area. Balikpapan has been chosen as the site of some important governmental agencies such as Komando Daerah Militer VI Tanjungpura and Kepolisian Daerah Kaltim. Balikpapan oil refinery is on the shore of Balikpapan Bay and covers an area of 2.5 square kilometers (0.97 square miles). Founded in 1922, it

10286-483: The Flying Females Mentoring Network. Men and women are required to undergo the same basic fitness tests to become a pilot; however the standards are lower for females. For some roles, the requirement cannot be adjusted for safety reasons. The rank structure of the nascent RAAF was established to ensure that the service remained separate from the Army and Navy. The service's predecessors, the AFC and

10425-519: The Great founded and created them with zeal. Jericho and Çatalhöyük , dated to the eighth millennium BC , are among the earliest proto-cities known to archaeologists. However, the Mesopotamian city of Uruk from the mid-fourth millennium BC (ancient Iraq) is considered by most archaeologists to be the first true city, innovating many characteristics for cities to follow, with its name attributed to

10564-656: The Pacific, participated in the Berlin Airlift , Korean War , Malayan Emergency , Indonesia–Malaysia Confrontation , Vietnam War , and more recently, operations in East Timor , the Iraq War and subsequent intervention, and the War in Afghanistan . The RAAF operates the majority of the ADF's fixed wing aircraft, although both the Australian Army and Royal Australian Navy also operate aircraft in various roles. The RAAF provides support across

10703-582: The Persian Gulf and North Arabian Sea in support of Coalition warships and boarding parties, as well as conducting extensive overland flights of Iraq and Afghanistan on intelligence, surveillance and reconnaissance missions, and supporting counter-piracy operations in Somalia. From 2007 to 2009, a detachment of No. 114 Mobile Control and Reporting Unit RAAF was on active service at Kandahar Airfield in southern Afghanistan . Approximately 75 personnel deployed with

10842-646: The Philippines had provided the Permesta rebels in North Sulawesi with an insurgent air force, the Angkatan Udara Revolusioner (AUREV). On 28 April 1958, a CIA pilot, William H. Beale , flying a B-26 Invader bomber aircraft that was painted black and showing no markings, dropped 500 pounds (230 kilograms) of four bombs on Balikpapan. The first damaged the runway at Sultan Aji Muhammad Sulaiman Airport ,

10981-483: The RAAF roundel was proposed, including the Southern Cross , a boomerang , a sprig of wattle , and a red kangaroo . On 2 July 1956, the current version of the roundel was formally adopted. This consists of a white inner circle with a red kangaroo surrounded by a royal blue circle. The kangaroo faces left, except when used on aircraft or vehicles, when the kangaroo should always face forward. Low visibility versions of

11120-535: The RAAF's formation aerobatic display team. They perform around Australia and Southeast Asia, and are part of the RAAF Central Flying School (CFS) based at RAAF Base East Sale , Victoria. The Roulettes operate the Pilatus PC-21 and formations for shows are a group of six aircraft. The pilots learn many formations including loops, rolls, corkscrews and ripple rolls. Most of the performances are done at

11259-507: The RAAF's main operational formation in the Pacific, the First Tactical Air Force (1st TAF), consisted of over 21,000 personnel, while the RAAF as a whole consisted of about 50 squadrons and 6,000 aircraft, of which over 3,000 were operational. The 1st TAF's final campaigns were fought in support of Australian ground forces in Borneo , but had the war continued some of its personnel and equipment would likely have been allocated to

11398-619: The RAAF. In 1922, the colour of the RAAF winter uniform was determined by Air Marshal Sir Richard Williams on a visit to the Geelong Wool Mill. He asked for one dye dip fewer than the RAN blue (three indigo dips rather than four). There was a change to a lighter blue-grey when an all-seasons uniform was introduced in 1972 by Chief of Air Force Air Marshal Colin Hannah. The original colour and style were re-adopted from 1 January 2000 under direction from

11537-690: The Second World War. About nine percent of the personnel who served under British RAF commands in Europe and the Mediterranean were RAAF personnel. With British manufacturing targeted by the German Luftwaffe , in 1941 the Australian government created the Department of Aircraft Production (DAP; later known as the Government Aircraft Factories ) to supply Commonwealth air forces, and the RAAF

11676-671: The South and East, and by Penajam North Paser Regency to the West. The city is divided into 6 districts ( kecamatan ) subdivided into 34 urban villages ( kelurahan ) tabulated below with their 2010 and 2020 Census populations, together with the official estimates as at mid 2023. Wilayah District ( kecamatan ) in km Census 2010 Census 2020 Estimate mid 2023 of Sub-district (kelurahan) codes ( Balikpapan Timur ) ( Balikpapan Barat ) (Balikpapan Utara) (Balikpapan Tengah) (Balikpapan Selatan) (Balikpapan Kota) Notes: (a)

11815-921: The UN planes were confronted by North Korean Mikoyan-Gurevich MiG-15 jet fighters, 77 Sqn acquired Gloster Meteors , however the MiGs remained superior and the Meteors were relegated to ground support missions as the North Koreans gained experience. The air force also operated transport aircraft during the conflict. No. 77 Squadron flew 18,872 sorties, claiming the destruction of 3,700 buildings, 1,408 vehicles, 16 bridges, 98 railway carriages and an unknown number of enemy personnel. Three MiG-15s were confirmed destroyed, and two others probably destroyed. RAAF casualties included 41 killed and seven captured; 66 aircraft – 22 Mustangs and 44 Meteors – were lost. In July 1952, No. 78 Wing RAAF

11954-400: The adjacent valleys. The altitude of Balikpapan ranges from 0 to 80 meters (260 feet) above sea level. The city proper itself is located on eastern side of Bay of Balikpapan . Most of the soil in Balikpapan contains yellow-reddish podsolic soil and alluvial and quartz sand, making it extremely prone to erosion. Balikpapan features a tropical rainforest climate ( Köppen : Af ) as there

12093-518: The air force used the red, white and blue roundel of the RAF. However, during the Second World War the inner red circle, which was visually similar to the Japanese hinomaru , was removed after a No. 11 Squadron Catalina was mistaken for a Japanese aircraft and attacked by a Grumman Wildcat of VMF-212 of the United States Marine Corps on 27 June 1942. After the war, a range of options for

12232-530: The ancient capital of Ghana, and Maranda , a center located on a trade route between Egypt and Gao. The dissolution of the Roman Empire in the West was connected with profound changes in urban fabric of western Europe. In places where Roman administration quickly weakened urbanism went through a profound crisis, even if it continued to remain an important symbolic factor. In regions like Italy or Spain cities diminished in size but nevertheless continued to play

12371-409: The area until Indonesian state-owned Pertamina took it over in 1965. Lacking technology, skilled manpower, and capital to explore the petroleum region, Pertamina sublet petroleum concession contracts to multinational companies in the 1970s. With the only oil refinery site in the region, Balikpapan emerged as a revitalized center of petroleum production. Pertamina opened its East Borneo headquarters in

12510-460: The athletic, artistic, spiritual, and political life of the polis. Rome was the first city that surpassed one million inhabitants. Under the authority of its empire , Rome transformed and founded many cities ( Colonia ), and with them brought its principles of urban architecture, design, and society. In the ancient Americas , early urban traditions developed in the Andes and Mesoamerica . In

12649-456: The backbone of the air war against the CTs, conducting bombing missions against their jungle bases. Although results were often difficult to assess, they allowed the government to harass CT forces, attack their base camps when identified and keep them on the move. Later, in 1958, Canberra bombers from No. 2 Squadron RAAF were deployed to Malaya and took part in bombing missions against the CTs. During

12788-518: The badge is a wedge-tailed eagle . Per Ardua Ad Astra is attributed with the meaning "Through Adversity to the Stars" and is from Sir Henry Rider Haggard's novel The People of the Mist . The "Eagles of Australia" is the official march of the RAAF and is played as a quick march when the RAAF bands perform public duties in the capital. Composed by the RAAF's Director of Music, Squadron Leader Ron Mitchell (who

12927-407: The benefit of mitigating the urban heat island effect, especially in cities that are in warmer climates. These spaces prevent carbon imbalances, extreme habitat losses, electricity and water consumption, and human health risks. The urban structure generally follows one or more basic patterns: geomorphic, radial, concentric, rectilinear, and curvilinear. The physical environment generally constrains

13066-663: The border ecosystem of Wain River forest. The urban forest in Telagasari, which was inaugurated in 1996 with an area of 29.4 hectares (73 acres), has now shrunk to just around 8 hectares (20 acres). The forest in the middle of this city has been surrounded by residential areas. The protected forest of the Manggar River also suffered considerable damage, which is around 60%. The reservoirs in this forest are also threatened because coal mining fields and brick mills were set up so close that there

13205-426: The city, followed by branch offices established by other international oil companies. Hundreds of laborers from Indonesia, along with skilled expatriates who served as managers and engineers, flocked into the city. Topography of Balikpapan is generally hilly (85%), with only small areas of flat land (15%), mostly along the coast and surrounding the hilly areas. The hills are less than 100 meters (330 feet) higher than

13344-548: The command of the RAAF, including the famous B-24 Liberator Shady Lady , attacked the oil refineries in August 1943 from Darwin, Australia . Amazingly, there were no aircraft losses, despite the crash landing and subsequent repair of the Shady Lady . In September and October 1944, the 5th and 13th Air Forces under the command of General George Kenney launched a series of five raids from Morotai and Noemfoor Islands. Kenney

13483-536: The early Old World cities, Mohenjo-daro of the Indus Valley civilization in present-day Pakistan , existing from about 2600 BC, was one of the largest, with a population of 50,000 or more and a sophisticated sanitation system . China's planned cities were constructed according to sacred principles to act as celestial microcosms . The Ancient Egyptian cities known physically by archaeologists are not extensive. They include (known by their Arab names) El Lahun ,

13622-671: The efficiency of transportation and the smaller land consumption , dense cities hold the potential to have a smaller ecological footprint per inhabitant than more sparsely populated areas. Therefore, compact cities are often referred to as a crucial element in fighting climate change. However, this concentration can also have some significant negative consequences, such as forming urban heat islands , concentrating pollution , and stressing water supplies and other resources. A city can be distinguished from other human settlements by its relatively great size, but also by its functions and its special symbolic status , which may be conferred by

13761-479: The emergence of an Atlantic trade. However, most towns remained small. During the Spanish colonization of the Americas, the old Roman city concept was extensively used. Cities were founded in the middle of the newly conquered territories and were bound to several laws regarding administration, finances, and urbanism. The growth of the modern industry from the late 18th century onward led to massive urbanization and

13900-791: The first millennium AD, the Khmer capital of Angkor in Cambodia grew into the most extensive preindustrial settlement in the world by area, covering over 1,000 km and possibly supporting up to one million people. West Africa already had cities before the Common Era , but the consolidation of Trans-Saharan trade in the Middle Ages multiplied the number of cities in the region, as well as making some of them very populous, notably Gao (72,000 inhabitants in 800 AD), Oyo-Ile (50,000 inhabitants in 1400 AD, and may have reached up to 140,000 inhabitants in

14039-513: The forest even though the surrounding area had been lined with wire. Previously between 2000 and 2001, illegal logging occurred in 10 to 15 points in the Wain River forest, and in 2009 this forest was hit by a fire along with the Manggar River forest which made 15 hectares (37 acres) of forest area engulfed in fire. The threat of coal mining from the surrounding area which provides mining permits such as Paser and Kutai Kartanegara also disrupts

14178-440: The form in which a city is built. If located on a mountainside, urban structures may rely on terraces and winding roads. It may be adapted to its means of subsistence (e.g. agriculture or fishing). And it may be set up for optimal defense given the surrounding landscape. Beyond these "geomorphic" features, cities can develop internal patterns, due to natural growth or to city planning . In a radial structure, main roads converge on

14317-565: The ground. Upon Indonesia's independence, BPM extended its activities in Balikpapan until 1965 when Pertamina , the Indonesian state-owned oil company, took control over the ownership of BPM and its oil exploration activities. There are several popular stories and legends explaining the origin of Balikpapan: The city has had several nicknames throughout its history such as the Oil City, City of Believers ( Kota Beriman ), which uniquely "BERIMAN" word

14456-523: The habitat of sun bears, so its are reluctant to reproduce. In addition to sun bears, other Balikpapan animals that are declared endangered are proboscis monkeys , borneo gibbon , bornean orangutans , pangolin and otter civet . Whereas extinct animals in Balikpapan are Bornean Banteng ( Bos javanicus lowi ). Balikpapan is bordered by Kutai Kartanegara Regency to the North, by the Makassar Strait to

14595-563: The intention of undermining Sukarno's government. The day before attacking Balikpapan, Beale had also damaged a Shell complex at Ambon, Maluku . His Balikpapan raid succeeded in persuading Shell to suspend tanker services from Balikpapan and withdraw shore-based wives and families to Singapore . However, on 18 May Indonesian naval and air forces off Ambon Island shot down an AUREV B-26 and captured its CIA pilot, Allen Pope . The US immediately withdrew support for Permesta, whose rebellion rapidly diminished thereafter. Shell continued operating in

14734-468: The land surface of the Earth. Town siting has varied through history according to natural, technological, economic, and military contexts. Access to water has long been a major factor in city placement and growth, and despite exceptions enabled by the advent of rail transport in the nineteenth century, through the present most of the world's urban population lives near the coast or on a river. Urban areas as

14873-475: The longest continual inhabitation . Cities, characterized by population density , symbolic function, and urban planning , have existed for thousands of years. In the conventional view, civilization and the city were both followed by the development of agriculture , which enabled the production of surplus food and thus a social division of labor (with concomitant social stratification ) and trade . Early cities often featured granaries , sometimes within

15012-492: The multi-millions, have proliferated into the dozens, arising especially in Asia, Africa, and Latin America. Economic globalization fuels the growth of these cities, as new torrents of foreign capital arrange for rapid industrialization, as well as the relocation of major businesses from Europe and North America, attracting immigrants from near and far. A deep gulf divides the rich and poor in these cities, which usually contain

15151-518: The number of arrivals during 2012 of 21,486 people, the highest number in the past three years. The number of migrants was able to exceed the number of newcomers who entered in Singapore in the same year which was as many as 20,693 inhabitants. The highest number of arrivals came from Java, which was 30%, then followed by Banjar and Bugis each by 20%, Toraja by 11%, Madura by 8%, Buton by 7% and Betawi by 4%. Based on Indonesian Most Liveable City Index which measured 27 indicators in every 2 years, Balikpapan

15290-621: The oil industry. This resulted in the economic boom of Balikpapan and attracted many migrants and expatriates. During World War II , the Empire of Japan occupied the city in 1942, as part of the occupation of the Dutch East Indies , and it was bombed by the Allies in first Balikpapan Battle in 1942 and second battle in 1945 . The battles impacted critical infrastructure, including the oil refinery stations and seaport which were completely burned to

15429-756: The outbreak of the Second World War, Australia joined the Empire Air Training Scheme , under which flight crews received basic training in Australia before travelling to Canada for advanced training. A total of 17 RAAF bomber, fighter, reconnaissance and other squadrons served initially in Britain and with the Desert Air Force located in North Africa and the Mediterranean . Thousands of Australians also served with other Commonwealth air forces in Europe during

15568-527: The peacekeeping operations in East Timor from 1999. Australia's combat aircraft were not used again in combat until the Iraq War in 2003, when 14 F/A-18s from No. 75 Squadron RAAF operated in the escort and ground attack roles, flying a total of 350 sorties and dropping 122 laser-guided bombs. A detachment of AP-3C Orion maritime patrol aircraft were deployed in the Middle East between 2003 and 2012. These aircraft conducted maritime surveillance patrols over

15707-500: The public as well as forms of public land such as public domain and the commons . Western philosophy since the time of the Greek agora has considered physical public space as the substrate of the symbolic public sphere . Public art adorns (or disfigures) public spaces. Parks and other natural sites within cities provide residents with relief from the hardness and regularity of typical built environments . Urban green spaces are another component of public space that provides

15846-518: The remaining restrictions on women in frontline combat roles were removed, and the first two female RAAF fast jet fighter pilots graduated in December 2017. Air Force has implemented several programs to assist women who choose a pilot career. Entry to the Graduate Pilot Scheme is open to women who are currently undertaking a Bachelor of Aviation (BAv). Once qualified, women pilots are able to access

15985-866: The rise of new great cities, first in Europe and then in other regions, as new opportunities brought huge numbers of migrants from rural communities into urban areas. England led the way as London became the capital of a world empire and cities across the country grew in locations strategic for manufacturing . In the United States from 1860 to 1910, the introduction of railroads reduced transportation costs, and large manufacturing centers began to emerge, fueling migration from rural to city areas. Some industrialized cities were confronted with health challenges associated with overcrowding , occupational hazards of industry, contaminated water and air, poor sanitation , and communicable diseases such as typhoid and cholera . Factories and slums emerged as regular features of

16124-619: The roundel exist, with the white omitted and the red and blue replaced with light or dark grey. The RAAF badge was accepted by the Chester Herald in 1939. The badge is composed of the St Edward's Crown mounted on a circle featuring the words Royal Australian Air Force, beneath which scroll work displays the Latin motto Per Ardua Ad Astra , which it shares with the Royal Air Force. Surmounting

16263-680: The same location as Tenochtitlan ; while ancient continuously inhabited Pueblos are near modern urban areas in New Mexico , such as Acoma Pueblo near the Albuquerque metropolitan area and Taos Pueblo near Taos ; while others like Lima are located nearby ancient Peruvian sites such as Pachacamac . From 1600 BC, Dhar Tichitt , in the south of present-day Mauritania , presented characteristics suggestive of an incipient form of urbanism. The second place to show urban characteristics in West Africa

16402-607: The second set the British oil tanker SS  San Flaviano on fire and sank her and the third bounced off the British tanker MV  Daronia without exploding. Beale's fourth bomb set on fire and sank the Indonesian Navy Bathurst -class corvette KRI Hang Tuah , killing 18 crew and wounding 28. Before attacking Hang Tuah , Beale also machine-gunned the oil pipes to Shell's wharf. The CIA had orders to attack unarmed foreign merchant ships in order to drive foreign trade away from Indonesia and weaken its economy, with

16541-660: The southern Philippines in response to the Marawi crisis . In 2021, the Royal Australian Air Force commemorated its 100th anniversary. Later that year, on 29 November, the Hornet was officially retired from RAAF service, with a ceremony to mark the occasion taking place that day at RAAF Base Williamtown. In January 2022, two RAAF P-8A Poseidon maritime patrol aircraft and one C-130J Hercules departed RAAF Amberley and Richmond to conduct aerial reconnaissance of Tonga in

16680-486: The term and has challenged geographers seeking to classify territories according to an urban-rural binary. Metropolitan areas include suburbs and exurbs organized around the needs of commuters , and sometimes edge cities characterized by a degree of economic and political independence. (In the US these are grouped into metropolitan statistical areas for purposes of demography and marketing .) Some cities are now part of

16819-565: The then CAF Air Marshal Errol McCormack. Slip-on rank epaulettes , known as "Soft Rank Insignia" (SRI), displaying the word "AUSTRALIA" are worn on the shoulders of the service dress uniform. When not in the service dress or "ceremonial" uniform, RAAF personnel wear the General Purpose Uniform (GPU) as a working dress, which is a blue version of the Australian Multicam Camouflage Uniform . Originally,

16958-692: The time were unable to meet Australian requirements, in addition to British production demands, the Australian government established the Commonwealth Aircraft Corporation in 1936 and purchased some American aircraft. In September 1939, the Australian Air Board directly controlled the Air Force via RAAF Station Laverton , RAAF Station Richmond , RAAF Station Pearce , No. 1 Flying Training School RAAF at Point Cook, RAAF Station Rathmines and five smaller units. In 1939, just after

17097-486: The top 10, leaving Samarinda in top spot. Some multinational corporations operate in East Borneo. Companies including Baker Hughes (US), ChevronTexaco (US), Halliburton (US), Pertamina (Indonesia), Schlumberger (France), Thiess (Australia), TotalEnergies (France) and Weatherford International (US) use Balikpapan as their base of operations in the region. Governmental public services including Bank Indonesia ,

17236-412: The turn of the first millennium BC , encompassed numerous cities extending from Tyre , Cydon , and Byblos to Carthage and Cádiz . In the following centuries, independent city-states of Greece , especially Athens , developed the polis , an association of male landowning citizens who collectively constituted the city. The agora , meaning "gathering place" or "assembly", was the center of

17375-446: The urban landscape. In the second half of the 20th century, deindustrialization (or " economic restructuring ") in the West led to poverty , homelessness , and urban decay in formerly prosperous cities. America's "Steel Belt" became a " Rust Belt " and cities such as Detroit , Michigan, and Gary, Indiana began to shrink , contrary to the global trend of massive urban expansion. Such cities have shifted with varying success into

17514-575: The volume of sewage begins to exceed manageable levels. The local government of cities takes different forms including prominently the municipality (especially in England , in the United States , India , and other British colonies ; legally, the municipal corporation ; municipio in Spain and Portugal , and, along with municipalidad , in most former parts of the Spanish and Portuguese empires) and

17653-476: The wake of the 2022 Hunga Tonga–Hunga Ha'apai eruption and tsunami . According to Australian Defence News, the flights were to "help determine the extent of the damage [to Tongan infrastructure]… and inform future disaster support requests." In October 2023, the Australian Government announced that, in addition to a further round of A$ 31.6 million for military assistance for Ukraine, it would be sending

17792-422: The war, they accounted for almost twenty percent of those killed in action. This statistic is further illustrated by the fact that No. 460 Squadron RAAF , mostly flying Avro Lancasters , had an official establishment of about 200 aircrew and yet had 1,018 combat deaths. The squadron was therefore effectively wiped out five times over. Total RAAF casualties in Europe were 5,488 killed or missing. The beginning of

17931-512: The world's population lived in cities. The cultural appeal of cities also plays a role in attracting residents. Urbanization rapidly spread across Europe and the Americas and since the 1950s has taken hold in Asia and Africa as well. The Population Division of the United Nations Department of Economic and Social Affairs reported in 2014 that for the first time, more than half of the world population lives in cities. Latin America

18070-576: The year. In Wain River Protection Forest, which is the main water catchment area and habitat for endangered species of Borneo , the community begins to encroach on how to burn it so that during the dry season some areas become barren and damage 40%. The area of Wain River forest reaches 10,000 hectares (25,000 acres), slowly but surely continues to decrease, leaving 9,000 hectares (22,000 acres) with forest conditions that are still good at only 63 percents. Residents around looked for wood to cook in

18209-532: Was Dia , in present-day Mali , from 800 BC. Both Dhar Tichitt and Dia were founded by the same people: the Soninke , who would later also found the Ghana Empire . Another ancient site, Jenné-Jeno , in what is today Mali , has been dated to the third century BCE. According to Roderick and Susan McIntosh, Jenné-Jeno did not fit into traditional Western conceptions of urbanity as it lacked monumental architecture and

18348-570: Was a strong advocate for using the powerful B-29 Superfortress for this raid but was forced to use the B-24 Liberator instead. Unbeknownst to the Allied forces, the Japanese Air Force had conserved many of its dwindling numbers of fighters to protect the important oil refineries. The first two raids did not have fighter cover and suffered severe losses. The 1945 Battle of Balikpapan concluded

18487-537: Was also director of the Air Force Band ), it was officially adopted as the RAAF's new march music on 23 March 1983, replacing the Royal Air Force March Past , which had long been the RAAF's march as well as the marchpast of other Commonwealth air forces. Subsequently, journalist Frank Cranston wrote lyrics to the march and a musical score was produced by September of the following year. The Roulettes are

18626-452: Was deployed to Al Minhad Air Base in the United Arab Emirates as part of the coalition to combat Islamic State forces in Iraq. Operations began on 1 October. A number of C-17 and C-130J Super Hercules transport aircraft based in the Middle East have also been used to conduct airdrops of humanitarian aid and to airlift arms and munitions since August. In June 2017, two RAAF AP-3C Orion maritime patrol aircraft were deployed to

18765-421: Was deployed to Malta in the Mediterranean where it formed part of a British force which sought to counter the Soviet Union's influence in the Middle East as part of Australia's Cold War commitments. Consisting of No. 75 and 76 Squadrons equipped with de Havilland Vampire jet fighters, the wing provided an air garrison for the island for the next two and half years, returning to Australia in late 1954. In 1953,

18904-413: Was eventually provided with large numbers of locally built versions of British designs such as the DAP Beaufort torpedo bomber , Beaufighters and Mosquitos, as well as other types such as Wirraways, Boomerangs, and Mustangs. In the European theatre of the war, RAAF personnel were especially notable in RAF Bomber Command : although they represented just two percent of all Australian enlistments during

19043-410: Was formed on 31 March 1921. King George V approved the prefix "Royal" in May 1921 and became effective on 13 August 1921. The RAAF then became the second Royal air arm to be formed in the British Commonwealth , following the British Royal Air Force . When formed the RAAF had more aircraft than personnel, with 21 officers and 128 other ranks and 153 aircraft. As British aircraft manufacturers at

19182-423: Was hit by heavy rains. Clean water supply is also decreasing because water absorption is narrowing, erosion is easily to occur and sediment from mining sites that flow into the river worsens and lowers reservoirs, coupled with Balikpapan conditions has few rivers and less fertile land. The population of the Balikpapan's mascot, the sun bear is fewer and only 50 are left. This is due to coal mining which narrows

19321-448: Was siltation of reservoir water. The majority of those who founded it were even known to be immigrant communities. In addition, the construction of the Samarinda-Balikpapan toll road planned by the East Kalimantan government which divides the forest for 8 kilometers across the reservoir could damage the quality of the clean water reserve in Balikpapan. Forest damage resulted in Balikpapan being easily hit by floods and landslides when it
