Kiamat Jakarta Sudah Dekat | Buka Mata

Summary

The video highlights Jakarta's struggle with sinking land due to severe land subsidence and the over-exploitation of groundwater. It explores the transformation of areas like Kampung Teko, once a dry village, now submerged in water. The footage traces the alarming rise in flooding and land sinking, with Jakarta predicted to be submerged by 2050 if no measures are taken. The city's rapid urbanization, loss of green spaces, and lack of proper water management have intensified the crisis. The video contrasts Jakarta's situation with Tokyo, which managed to halt land subsidence by stopping groundwater exploitation, offering a glimpse of potential solutions.

Takeaways

• 😀 Jakarta's Kampung Teko, also known as Kampung Apung, was originally a dry land area but has since become submerged due to rising water levels in the surrounding lake.
• 😀 The Kapuk cemetery, which was once above ground, is now also submerged and has shifted to the north, with the nearby Walladina Mosque now situated underwater.
• 😀 Jakarta has been gradually sinking for decades, with land subsidence affecting almost all areas of the city, causing many regions to slowly submerge.
• 😀 Since 1997, the sinking has become more widespread, with Kampung Apung experiencing a land subsidence rate of 15 cm per year, leading to homes being built on water.
• 😀 The land in the vicinity of Kampung Apung has dropped by 25 cm per year, leading to frequent flooding despite ongoing construction of sea walls.
• 😀 Even though sea barriers are continuously built, the threat of rising water levels remains ever-present for residents of coastal Jakarta.
• 😀 Jakarta is predicted to be half submerged by 2050, with significant portions of the city, including areas near the Istana Negara, to be underwater.
• 😀 The subsidence is not limited to coastal areas; significant land subsidence also occurs in central and southern Jakarta, such as the Gambir area near Istana Negara.
• 😀 Jakarta's rapid urbanization, coupled with increasing population growth, has led to an overwhelming demand for water, contributing to the excessive extraction of groundwater.
• 😀 Groundwater over-extraction is a significant factor in the city's land subsidence, as demonstrated by the comparison with Tokyo, where land subsidence stopped after halting the extraction of groundwater.

Q & A

What happened to Kampung Teko in West Jakarta?

Kampung Teko, once a dry land settlement, has transformed into 'Kampung Apung' (Floating Village) due to rising floodwaters. The area, which used to have houses on land, now sees houses built on water.

Why is the area near the mosque no longer accessible for worship?

The mosque, which was once on solid land, is now submerged in water and is no longer usable for worship. The last time people prayed there was in 2001 when the area was still land.

What is the main cause of Jakarta's sinking problem?

The main cause of Jakarta's sinking problem is land subsidence, which is occurring at an alarming rate. This is largely due to the over-extraction of groundwater and urbanization.

How much is the land subsiding annually in Kampung Apung?

In Kampung Apung, the land is sinking at a rate of 15 cm per year, which leads to the continual flooding of homes.

What is the extent of land subsidence across Jakarta?

Land subsidence is widespread across Jakarta, with some areas experiencing a sinking rate of up to 25 cm annually, making them prone to frequent flooding.

How are the residents of Jakarta coping with the sinking of their land?

Many residents of Jakarta, especially in coastal areas, have resorted to raising their houses to protect them from flooding. Some have even raised their homes multiple times to cope with the sinking land.

What is the predicted future of Jakarta's coastal areas by 2050?

By 2050, nearly half of Jakarta's land area is expected to be submerged, with the coastline advancing toward the Presidential Palace, potentially affecting up to 90% of Jakarta's coastal regions.

How does the exploitation of groundwater contribute to Jakarta's sinking?

The excessive extraction of groundwater in Jakarta has caused the land to sink because the natural water table is being depleted, leading to a reduction in the volume of underground water that supports the ground's stability.

How does the situation in Jakarta compare with Tokyo in terms of land subsidence?

Unlike Jakarta, Tokyo was able to halt land subsidence by stopping the exploitation of groundwater. In Tokyo, when groundwater extraction ceased, the rate of land subsidence stopped as well, but in Jakarta, the problem persists due to continued extraction.

What measures has Jakarta taken to address its sinking problem?

Jakarta has attempted to build sea walls and other flood defenses, but these measures have not been sufficient to address the underlying issue of groundwater depletion and land subsidence.
