Indonesia is one of the developing countries that has a lot of natural resources because of its wealth that spread throughout the archipelago and also its location is very strategic. This has caused many foreign countries to invest their shares and develop their economy in Indonesia.
Perhaps not only foreign countries, but also local companies that are in Indonesia. Do you know that usually the company building is located in Jakarta? Besides because Jakarta is the capital of Indonesia, Jakarta also has a velocity of money that can be spelled out better than other regions. To be honest, the construction of these skyscraper buildings has many negative impacts on the earth as well as our daily life.
Of the many skyscrapers in Indonesia, there are seven buildings that have a height of more than 200 meters. The seven buildings are Sahid Sudirman Center Jakarta with a height of 259 meters, Raffles Hotel Jakarta as high as 253 meters, Sinarmas MSIG Tower Jakarta as high as 245 meters, Seaview Condominium @ Green Bay (Pluit Tower J Jakarta) as high as 208 meters, 83 Seaview Condominium @ Green Bay ( Pluit Tower K Jakarta) as high as 208 meters, 83 Seaview Condominium @ Green Bay (Pluit Tower L Jakarta) as high as 208 meters, and 83 Seaview Condominium @ Green Bay (Pluit Tower M Jakarta) as high as 208 meters.
According to the Tata Tata Kota, Nirwono Yoga, the construction of tall buildings often ignores green open spaces. Based on the results of the research in Sudirman, Thamrin, and Kuningan, more than 90 percent of the land plots are hardened with concrete and asphalt. If all the plots are hardened, this will cause the surrounding area to be inundated and cause flooding due to the absence of water absorption in the area of ??the office lot.
Not only that, the buildings certainly need clean water, while the supply of water is less. This shortage of water supply, causing the owners of the building to do a large water sucking without any supervision. As a result of this deed, the decrease of ground level in Jakarta decreased by as much as 40 percent, as written on page Jakarta.go.id in 2010. However, this estimate estimates that 50 percent of Jakarta area will be below sea level within a period of 10 -20 years.
Meanwhile, the decline in land surface in Jakarta has already occurred from 1974. A quantitative data describes since 1974-2010 found the fact of land subsidence has decreased up to 4.1 meters. It happened in Muara Baru, Cilincing, North Jakarta. Not only that, a number of other areas such as in West Cengkareng have decreased 2.5 meters, Daan Mogot 1.97 meters, Ancol 1.88 meters (monitor point in Ancol tourism area), Cempaka Mas 1.5 meters, Cikini 0.80 meters and Cibubur 0.25 meters. You can imagine the effect was great, huh?
As we know also, skyscrapers located in Jakarta are almost all made of glass. The effects of this greenhouse can cause extreme weather changes due to global warming. First, the light coming into the earth is reflected again into the earth's atmosphere thus destroying the ozone layer.
In 2014, the Ministry of the Environment believes the effects of extreme hot weather are now not only felt in the mainland. In fact, at altitudes or above the atmosphere layer the heat stings are now increasingly felt.
"Usually a heat stroke when I am on the plane or 33 thousand feet altitude is not so felt, but now, the heat in this height really sting," said assistant deputy of complaints and implementation of sanctions administration Ministry of Environment Widodo Sambodo on Sunday (12/10). He explained that the heat sting that reached the height indicates that greenhouse gases have penetrated the atmosphere.
From all the above explanation, it can be seen that the construction of high buildings in Jakarta caused a lot of damage that occurred in this nature. By trying to make a garden or a small park on top of the building has at least helped reduce air pollution and release oxygen into the earth's atmosphere, this garden also provides a new habitat for birds or animals that previously lived in the area.
And for land subsidence, things like Rainwater Harvesting can be done or collect water coming from rainwater and reprocessed for use, green open spaces, groundwater injecting, or absorbing wells to minimize the impact of building construction the.Bibliography:
