BANDUNG - Secretary of West Java Iwa Karniwa ensures the preparation of this blueprint is important considering that West Java is the most "complete" potential natural disaster in Indonesia. "So there must be steps that are more systemically structured and coordinated in one plan," he explained on Wednesday (2/1/2019).
Armed with these documents, it can be a complete guide for residents in 27 regencies / cities in West Java so that being responsive to disasters also reduces the number of victims. "We are referring to those who have advanced in Japan, countries that have frequent earthquakes followed by tsunamis but few victims," ??he said.
Iwa claimed that according to the governor's order he had ordered the West Java Regional Disaster Management Agency (BPBD) to coordinate with the regions regarding data supply and disaster maps. "All involved included historical data and disaster maps in 27 districts and cities. Including education about the shape and construction of buildings, "he said.
Previously, West Java BPBD Chief Executive Dicky Saromi explained that there were several factors that contributed to the high potential of disaster in West Java. First, in terms of forest land cover, which is still below 20% on average for all watersheds. Ideally the area of ??forest cover is around 30% for each watershed.
Second, the potential for surface water where rainfall reaching 48 billion cubic meters per year can only be used for 15 billion cubic meters. While the rest is wasted into the ground or becomes run off.
"This is what we see, most of which is wasted into the sea or run off. If it becomes a run off, it will become a flood if the water system is not good, especially the drainage or flow of water. This is what we must pay attention to, "he said.
The third factor is the layout and building. He considered the spatial planning and building must have been tightened, so that the escalation of disasters every year would not be higher. "In addition, the flood control building must be accelerated," he said. (Even)
