Pemodelan Spasial Bahaya dan Kerentanan Bencana Banjir di Wilayah Timur Kabupaten Cirebon

Abstract

As a tropical climate region in the world, Indonesia has high vulnerable to floods disaster. In West Java, flood is annual disaster that occurs in the eastern region of Cirebon Regency. On 2018, there are thirteen sub-districts in the region have flood up to 2 meters. The study aims to determine the flood hazard and vulnerability in the eastern region of Cirebon Regency. The analysis of flood hazard includes six parameters such as elevation, slope, rainfall, infiltration capacity, distance to river, and surface runoff. Whereas, the flood vulnerability analysis includes parameters of land use, population, and road network. All parameters is analysed using overlay analysis with geographic information system to result the flood hazard and vulnerability model. The results shows the eastern region of Cirebon Regency has flood hazard in very high category reach 22.98 percent, high 33.54 percent, medium 21.80 percent, low 16.60 percent and 5.07 very low percent. Meanwhile, the flood vulnerability map show the cultivation land and built-up land use are most affected by the disaster. The potential number of vulnerable population is very high and high category reach 609,738 peoples who spread in the southeast of region. Whereas, the flood vulnerability to road network reach 3.3 to 6.84 km / km2. The flood hazard occurs in the alluvial plains, floodplains, and back swamps between Cisanggarung and Ciberes watersheds who known as suitable for settlement. Thus, up-land management is sustainable effort to resolve the problem.

Knowledge and Attitude of Junior High School Students Towards Hydrometeorological Disaster Preparedness: A Case Study in Cirebon City, Province of West Java

“…The risk of natural disasters is also high, influenced by geological conditions, geomorphology, meteorology and urbanization factors. Cirebon is an area that passes through the earthquake zone with high rainfall conditions during the rainy season in certain areas with steep topography conditions that can pose a risk of natural disasters such as floods, or landslides [9]. Highly dynamic human activity in urban areas combined with the meteorological conditions of beetle winds during the dry season period further makes the potential for heat and drought very high [10].…”

The impact of Cirebon coal-fired power plants on water quality in Mundu Bay, Cirebon Regency

“…This research was conducted in the Mundu Bay around the PLTU Cirebon I and II sites. The area of interest (AOI) (Sanchez, 2014;Widiawaty & Dede, 2018).…”

Assessing the Influence of Land-Use Changes on Water Quality Using Remote Sensing and GIS: A Study in Cirata Reservoir, Indonesia

“…15.4% directly and 5.9% indirectly. Settlements area increases the water discharge due to lower absorption ability of land surface caused by asphalt or cement (Widiawaty and Dede, 2018), then eventually increase the sediment runo when owing across the bare land (Arsyad, 2009). Therefore, 49.86% increase in the settlement area, in the period of 2004-2014, had a positive e ect on the uctuation of TSS content by 23.70 %.…”
