Model of regional vulnerability against CO2Toxic Gas disasters at Mount Dieng (case study: Timbang Crater, Batur Sub-District, Banjarnegara District)

Abstract

One of the sub-districts that are vulnerable to toxic gas disasters is Batur Subdistrict, Banjarnegara District.For that people living in the vicinity of the crater should always be ready for the national disaster of toxic gas that had killed 149 people on February 20, 1979 did not happen again.The purpose of this research is to make the model of vulnerability of area to toxic gas disasters of CO2 Timbang crater in Batur Sub-District by using Analytical Hierarchy Process (AHP).The population in this study is the entire head of the family located in Batur Sub-District, Banjarnegara District, Central Java Province, amounting to 37 heads of household.To take the sample used Simple Random Sampling method.Data analysis techniques through weighting of the three aspects are exposure, sensitivity, and adaptive capacity.In each aspect the parameters are weighted using input from the experts by the AHP method.The vulnerability of the area to the toxic gas catastrophic CO2 is classified into three levels of vulnerability are, low, medium, and high. Based on the research result, the vulnerability level in Batur sub-district is only divided into two classes, namely for the vulnerability class being found in 6 villages are, Pekasiran Village, Pesurenan, Sumberejo, Karang Tengah, Bakal, and Dieng Kulon. For the high grade, there are 2 villages: Batur, and Kepakisan. This happens because the level of exposure and sensitivity is much higher than the adaptive capacity of the community.
