Kajian Resiko Bencana Alam Patahan Lembang di Kecamatan Lembang, Parompong, Dan Cisarua Kabupaten Bandung Barat

Abstract

Abstract. Lembang fault area is an area that is prone to earthquakes. Apart from being a medium of propagation of earthquake waves from the fault-active fault in West Java. Fault dent from 2009 to 2015 experienced a movement of 22 to 29 km which lead to more risk of disaster. With the state of the fault is still active dent, land conversion followed by a lot of people living around the fault lembangs and low public awareness about making disaster risk study in the area of the fault is very necessary.Based on these problems, studies need to be done in the area of risk assessment. The goal is to know the extent of the disaster risk in Lembang Fault Zone which was creeping up to 7 km with population density and land conversion are high in the region. The method used to calculate the level of risk of disaster is BNPB Risk Index Method No. 02, 2012. The components what counts is the level of threat, vulnerability level (social, economic, physical building and the environment) as well as the level of regional capacity. Based on the analysis, the level of disaster risk in the study area of "low", "medium" to "high". The village is high risk of disaster is the village Karyawangi, Cigugurgirang, Cihanjuang and Kertawangi. Village by village disaster risk being is Langensari, Cihideung, Cihanjuang Kingdom, Pagerwangi, Ciwaruga, Jambudīpa and Padaasih. While villages with a low level of disaster risk are Village Lembang, Wood Ambon, Warehouse Kahuripan and Pasirhalang.

Abstrak. Daerah patahan lembang merupakan daerah yang sangat rawan dengan gempa bumi. Selain sebagai media rambat gelombang gempa bumi dari sesar-sesar aktif lainnya di Jawa Barat. Patahan lembang dari tahun 2009 hingga 2015 mengalami pergerakan dari 22 sampai 29 km yang mengakibatkan semakin banyak resiko bencana. Dengan keadaan patahan lembang yang masih aktif, alih fungsi lahan disusul banyak penduduk yang hidup di sekitar patahan lembang dan rendah kesadaran masyarakat sekitar membuat kajian risiko bencana di daerah patahan sangat perlu dilakukan. Berdasarkan permasalahan tersebut, perlu dilakukan studi kajian resiko di kawasan tersebut.  Tujuannya mengetahui sejauh mana tingkat resiko bencana di Kawasan Patahan Lembang yang sudah merambat hingga 7 km dengan kepadatan penduduk dan alih fungsi lahan yang tinggi di kawasan tersebut.
