Get to know the artificial island in Dubai

Dubai is a city full of wealth that has many artificial islands Dubai is one of the cities in the United Arab Emirates and its health is identical to its natural resources in the form of petroleum because that's why many people think that Dubai is a rich city because it is located in The Arabian Gulf, which has abundant petroleum resources, but people's assumptions are wrong because most of Dubai's income is not from petroleum but from other sectors that are rarely known by many people. Here are some facts about the Dubai Dubai artificial island mega project. one of the seven emirates which is the most populous city located along the south coast of the Persian Gulf these 2 are the richest and most luxurious cities in the Middle East whose population is dominated by foreigners and only 20% are natives of Dubai Dubai has the largest GDP compared to other cities in the United Arab Emirates which is about 100 billion dollars or equivalent to 1450 Trillion Rupiah. However, it turns out that only 7% of the total GDP income comes from oil while the rest comes from the aviation and port tourism business. This is because the Dubai oil field, which was first discovered in 1966, does not have many oil reserves The inside is different from the oil fields in Abu Dhabi because they don't want to be too dependent on the little oil. Finally, with the leadership of Sheikh Rasyid bin Said Al Maktoum at that time, Dubai adopted a western system by making Dubai a city of trade and industry. Jebel Ali Port and Jebel Ali port were built in the late 1970s today this port is the largest and largest man-made port and also the busiest port in the Middle East and the 9th busiest in the world the reason why this Central Port is the busiest in the world a is because this port is located in the Jalan Alif Rizon or Jafza-Jafza area, this is the largest economic free zone in the world which has an area of ​​about 57 km2 within the economic free zone, it has regulations that benefit investors such as no taxes and import duties. for foreign companies, 45% reduction in rental fees for offices that are just starting a business and there are no restrictions on foreign investment ownership with the existence of this Prosecutor, making foreign investors set up thousands of companies in the area where the total investment reaches 20% of Dubai's total GDP apart from Dubai's Jebel Ali port also has the largest airport in the world called Al Maktoum International Airport which is also in the city of Jafza at this international airport. It is also the busiest airport in the world, which can accommodate up to 160 million passengers, and this airport also has a very large contribution. in Dubai where as much as 37.5% of Dubai's total GDP comes from Dubai International Airport, it is not only the ports and airports that make Dubai the richest city but also because of the many artificial islands that are being built along the coast of Dubai. land reclamation technique, namely the creation of new land in the coastal area in the construction of this artificial island does not use concrete or steel but only uses natural materials such as stone and sand in the construction process of the construction of the artificial island as in

1.Palm Jumeirah a breakwater wall is built around the artificial island. This breakwater or the following functions to block the big waves that come so as not to go to the artificial island in which it is built by piling the base the sea with sand and then on top it is given compliance until it is above sea level along with the construction of the breakwater. After that, the rocks are backfilled with sand which is taken from the seabed using a dredger to form palm leaves and so that the shape of this artificial island is precise and accurate. these technicians use the help of GPS technology to keep the soil of this artificial island stable and not sinking the technicians then use a soil compactor, namely vibro convection, this tool produces vibrations and vibrates the surrounding soil so that the soil becomes solid and stable after that only then Installed various kinds of infrastructure on top of the artificial island, some of the largest artificial islands in Dubai, including the first is Palm Jumeirah Palm Jumeirah is an artificial island built in 2001 by a company called Natkal, a company owned by by the Dubai government the shape of this Palm Jumeirah is shaped like a palm tree with a trunk that has 17 leaves and there is a crescent-shaped island surrounding it which functions as a breakwater with a length of 17 km. The construction of this Palm Jumeirah cost 12 billion and 1 dollar or equivalent to rp174,000 this Jumaira palm is made from 7000000 Tons of rock blasted from the nearby Al-Azhar Mountains and more than 94 million M3 of sand dredged from the seabed to make this Island have a population of 11000 people and this area reaches 5.72 kilometers With the Palm Jumeirah, tourism in Dubai is increasing and doubling the coastline in Dubai, then other islands are

 2.Palm jebel Ali construction of Palm jebel was started in October 2002 and is planned to be completed in mid 2008 it is built using more than 200000000 cubic meters of stone and sand making it 50% bigger than Palm jumeirah in the construction process of 30000 stones and sand is sent by truck from all over the United Arab Emirates to the construction site of Palm Jebel Ali every day after the land reclamation process was completed in 2007 this development plan was continued with infrastructure development which began in 2008. However, the construction of Palm Jebel Ali was stopped in that year due to the monetary crisis that hit the entire territory of the United Arab Emirates even as a result of the developer temporarily returning some money to several investors in 2011 was an artificial island whose construction was also the Palm Island area which is the most ambitious construction project in Indonesia. Dubai Development This area was announced in 2004 and is planned to be built 10 times wider than Palm Jumeirah and 5 times wider than Palm Jebel Ali as much as 1 billion M3 of sand dredged to build Palm in this area but in 2008 the construction of Palm Jumaira was also stopped due to monetary crisis then the developer revised the Palm development plan for this area which aims to save time and money this revised project later changed its name to an Islamic area consisting of 3 small islands and the construction of land reclamation for the Medan area was completed in 2013 then in 2016 the bridge connecting these three small islands was completed and in 2020 this area was officially opened to the public. 100 meters between island one and island others and the names of these islands  based on the names of the countries in the world. However, due to the monetary crisis in 2008 only 2 of the 300 islands that were completed, namely the island of Lebanon and the island of Greenland, in 2013 this project was finally revised into a basic tube project
