Abstract

An earthquake disaster is an event that causes various damage and loss of life. This study aims to determine the vulnerability of earthquake hazards in Bengkaung Village, West Lombok Regency. The method used in this research is the geomagnetic method. The results of this: study indicates the value of the magnetic field anomaly in the range of -1100 nT-1500 nT. 2D modeling with 4 paths shows that the study area is dominated by 5 rock layers with a susceptibility range between (0.013 - 6.21)×10^(-3) in SI, which consists of sandstone, clay, fractured andesite lava, fresh andesite lava. and granite. The highest vulnerability to earthquake hazards is in the southern part of Bengkaung Village, due to the presence of a cohesive soil type (like clay) on the surface of the study area, coupled with the presence of intrusions and faults. Meanwhile, the western part of Bengkaung Village and the northern part of the Bengkaung area have a relatively smaller earthquake hazard vulnerability than the southern part. This is because the western and northern parts have the main layer of non-cohesive soil (sandstone) which has high shear strength and becomes a damper in wave propagation when an earthquake occurs

Abstract

Desa Bagik Polak Barat terletak di Kecamatan Labuapi, Lombok Barat. Populasinya terdiri dari 50% petani, 30% pengusaha rumahan, dan 20% profesi lainnya. Salah satu potensi yang ada di Desa Bagik Polak Barat adalah tanaman pisang. Tanaman pisang banyak dibudidayakan oleh masyarakat di kebun, sawah dan pekarangan. Pemanfaatan tanaman pisang belum maksimal, hanya buahnya diambil sedangkan batangnya dibuang saja. Batang pisang dapat dimanfaatkan dengan sedikit sentuhan inovasi untuk menjadi produk yang memiliki nilai ekonomis tinggi. Hasil yang diperoleh komunitas mitra melalui kegiatan inovasi tersebut adalah keterampilan, Mitra telah memanfaatkan inovasi dan optimalisasi produk. Kegiatan ini telah berjalan dengan baik dan sesuai ekspektasi berkat kerjasama yang baik dengan mitra kerja dan kontribusinya selama kegiatan berlangsung. Jajanan Kedebong Taro yang inovatif ini dipasarkan dengan dua cara yaitu dijual kepada masyarakat sekitar baik melalui pasar maupun dengan menitipkannya ke warung-warung. Kedua, melalui E-commerce, agar pemasaran menjadi lebih global. Dengan demikian diharapkan melalui produk ini perekonomian masyarakat menjadi salah satu makanan andalan pulau Lombok yang berasal dari Desa Bagek Polak Barat.

Abstract

The Bengkaung area, Batulayar District, West Lombok is suspected to be very vulnerable to the risk of earthquake hazards. However, in this area no scientific research, either geological or geophysical, has ever been carried out regarding this hazard. How are the physical characteristics of the lithology and structure in the area to the risk of earthquake disaster? The purpose of this study was to determine the physical characteristics of the lithology and subsurface structures that were validated by the level of damage. The method used is the geoelectric method and local building damage data. The results of the 2D geoelectric anomaly modeling show the characteristics of the subsurface lithological layers in the form of sand, sandstone, clay, andesite lava faults, fresh andesite lava, and granite. The fault was detected in the center of the study area in a north-south direction. Earthquake hazard analysis shows that the cause of the high risk of earthquake hazard in Bengkaung Village is the presence of faults and cohesive lithology. The highest potential risk is in the southern part of Bengkaung Village. The southern area of ​​Bengkaung Village is dominated by clay that has cohesive properties, especially on the surface. The western and northern parts of Bengkaung Village have medium and low vulnerability to earthquake hazards. The last two areas are dominated by non-cohesive soils in the form of sandy soils and lapilli pumice
