Flood in Bandung Not Flood Ordinary

Flood in Bandung Not Flood OrdinaryFlood is one of the urban problems that are still difficult to resolve. Due to various factors, several cities in Indonesia have become flood subscriptions, one of them is Bandung. A few days ago, we were shocked by a flood video in Pasteur, Bandung that took a lot of attention.

Looking back at the Bandung floods that occurred in March, mentioned that the flood was the worst. The flood that hit Bandung Regency at that time caused by overflow of Citarum River.

Bandung today that often flood does not happen without cause. The area of ??Bandung, especially the northern part, is slowly changing. According Kompasianer Rinsan Tobing, the northern area of ??Bandung which once was a green area and serves as a water catchment area, turned into residential and business areas, especially the proliferation of inns and restaurants. The green fields are arid. For tourist destinations and settlements, North Bandung area does have a very stunning scenery.

However, this change must result in a consequence. The destruction of the area with massive encroachment reduces green open space in Bandung area. The northern part of Bandung that should be the water absorption area has changed its function. This results in a lack of water entering the soil and rising surface waters that glide down into the lower areas.

Rinsan said that the flood in March 2016 is proof that South Bandung experienced the greatest impact of the massive changes that occurred in the area of ??North Bandung. The flood is also the worst flood in 10 years.

"From year to year, the floods are getting worse, besides the extent, the water is inundated.If the previous floods only up to Dayeuhkolot and Baleendah, the last floods to Banjaran and Arjasari, the sub-districts increased, besides due to its already damaged northern areas, eastern and western regions are suspected of contributing also to this year's floods. " wrote Rinsan.

He continued that the pattern of handling by the city government is still curative. The preventive effort has not yet emerged so that in the following years, it is feared that the South region will receive even greater floods, while the North will be more beautiful at night. "The North is preening, the South is stumbling, the northern hemispheres, the southern flooded," he added.

Viewed from another perspective, the thing that caused Bandung to experience massive flooding according to Aksi Cepat Tanggap (ACT) is the damage of land especially in the upper river Citarum. Agricultural technology practices and unsustainable land management are seen around the upstream area.

The magnitude of potato farming that causes erosion can result in land degradation and decreased river flow capacity due to high sedimentation. Planting elephant grass in the peak of Mount Wayang is also not an appropriate option to become a protected area with a steep slope.

People around the upstream easily ignore the preservation of nature because the main factor to meet the needs of life. One of them is that they get a decent and adequate livelihood from the use of elephant grass as cheap fodder.

According to the writer Muhajir Arif Rahmani of ACT, the problems faced by the Citarum river must be solved as a whole and not only can be done in certain locations. Therefore, the handling of Citarum requires the attention of all parties, from upstream to downstream.Arif continued, Baleendah district in Bandung regency which in the 70s about 90 percent of its territory is a rice field area, currently filled with buildings. From the 80s to the present day, nearly half the area of ??productive land in Baleendah is crammed with buildings, becoming an economic and office area. In this way, the water catchment area around Citarum is certainly reduced.

For this reason, Bojongsoang, Baleendah and Dayeuhkolot sub-districts become flood subscriptions. Because there has not been enough attention from the government to handle the flood, then in March the range of Bandung flood becomes more widespread. The flood is also more powerful impact to soak 35 thousand houses in 15 districts in the area of ??South Bandung.

All of these statements are evident in the extreme floods that occurred on October 24th yesterday. Quoted from kompas.com, the flood that occurred in Jalan Pasteur Bandung was even to swallow the loss of life. In addition, the floods also not only flooded the road surface. The rush of spilled water into the streets even dragged several vehicles.

One of the causes of rapid water overflow to the road is the poor drainage in the area of ??Pasteur. The condition is also exacerbated by the high rate of sedimentation in the area. In addition, there is also a delay in dredging sedimentation in the drains behind the Bandung Trade Mall (BTC) shopping center.

As an effort to handle floods in Bandung, not only improve the physical development, but also fix the government's commitment that has not shown the protection of its citizens (source). Habitat Partnership Executive Board, Nirwono Joga, said several things that must be addressed by the City and District Bandung. First, revitalization of drainage channels. The capacity of water in Bandung should be enlarged from 1.5 meters to 2.5 to 3 meters.

Second, change the government's response to overcome the flood. During this time, the government is thinking about how to dispose of water as much as possible when it rains. In fact, it should, how the water is accommodated. So when it rains, water can flow through the proper channels and empties into lakes, reservoirs, and so on.

In addition, according to Nirwono, Bandung also must increase Green Open Space (RTH). What is emphasized here is not only beautify the park, but also reproduce the garden. RTH Bandung must reach 30 percent if you do not want the flood to hit higher every year.

In addition, according to kompasianer ACJP Cahayahati, although floods of Bandung quickly receded because of its geographical position that tilted to the South, this can not be ignored constantly. There are several things that can be done by the city government and district of Bandung. According to him, first is not to add water avalanches. Since Bandung is surrounded by mountains and is located in this basin, its condition is very dependent from the water absorption around the slopes above it.

Rain water can be free "plunge" unimpeded by the continuing reduction of water catchment area in North Bandung. In fact, if the northern region is still a lot of trees, rain water that fell can be restrained to a depth of 15 cm. Not only built settlements, but also diverted to the culinary and tourist areas so that the opening of road access was also more and more. This means further reducing the catchment area for Bandung city and district below it.

Second, the river should be free of waste so that water on the culverts along the road can flow smoothly. According to ACJP, this is a difficult thing to change if from humans themselves do not intend to change. There should be an unusual breakthrough to change this. It also can not be resolved in a governor or mayor or regent program that only takes 5 years, but it may take up to decades to complete.

Third, there is no effect of climate change. ACJP writes that Bandung area, as predicted by BMKG, is indeed an area that has abnormal rainfall."This abnormal rainfall as part of the La Nina phenomenon According to the Head of Data and Information Center of the National Disaster Management Agency (BNPB) Sutopo Purwo Nugroho in its release on Wednesday, June 8, 2016 La Nina happened at the time of sea surface temperature conditions in the West Sumatra is warmer than sea temperatures on the east coast of Africa, thus increasing the supply of water vapor, leading to increased rainfall, in the western part of Indonesia, "the ACJP wrote.

Indeed the settlement of an urban problem can not be done by one party, namely the government or society alone. Both must contribute to each other and work together to solve the problems of the city together. It takes full awareness to make the city better. (FIA / YUD)
