Pemetaan Jalur Evakuasi Bencana Letusan Gunung Raung Dengan Metode Network Analisis

Abstract

Raung Mountain (highest peak: 3.344 m above sea level) is a conical volcano that located on the eastern tip of Java Island, Indonesia. Administratively, the area of the mountain was included in three districts in Besuki, East Java, there was Banyuwangi and Jember, Bondowoso,. Caldera Raung is also the largest dry Caldera in Java and Indonesia\u27s second-largest after mount Tambora in West Nusa Tenggara. Report on the increase of activity is given from the date June 21, 2015. The NASA satellite Landsat 8 detected two holes so that the magma is estimated not to be a big eruption began on June 26, 2015 and a series of eruptions since July 4, 2015. The disastrous evacuation path mapping mountain through disaster risk modelling raung minimizing loss due to disasters through the map.Disaster evacuation map is needed mapping risk Raung with stages of representation, threat representation map of vulnerability, modelling capacity, as well as the maping of risk. Threat representaion is composed of the threat of the burst of rock vulcanic and the threat of lava flows of Raung Mountain.. Representation of capacity are contain the elements of population and area of the region in the case of the risk of Raung Mountain disaster. Representation Vulnerability includes physical susceptibility , social vulnerability, and the vulnerability of the economy. While in modeling risk map is processed by using a formulation of natural disaster regulation relief Agency Heads (PERKA BNPB) No. 2 in 2012. After mapping the risk, this model is combined with other parameters to build a disaster evacuation map using network analysis method
