One hundred seventeen landslides occurred in Malang Regency throughout 2021, triggering the need for practical hazard assessments to strengthen disaster mitigation process. In terms of providing a solution investigating location more precisely, this research aims compare machine learning algorithms produce an accurate landslide susceptibility model. This applies three composed RF (random forest), NB (naïve Bayes), and KNN (k-nearest neighbor) 12 conditioning factors. The factors consist...
Abstract According to the Indonesian Disaster Management Agency (BNPB), Indonesia’s losses due landslides were estimated around hundreds of billion rupiah in 2017. Making landslide as one catastrophes with greatest risk loss and leaving a couple regions prone Indonesia, Pacitan region is them. Landslide delineation therefore represents particularly beneficial application evolving research trend disaster reduction, especially for vulnerable region. In present times open-access satellite data,...
Floods are the most common sort of natural disaster that occurs when a body water overflows and submerges on dry terrain. Several regions in Sidoarjo District, East Java such as Kedungbanteng Banjarasri Village, have experienced floods with varying heights since 2018 due to heavy rainfall areas. According Meteorological, Climatological, Geophysical Agency (BMKG), intensity these areas reach 100 mm/day. Furthermore, physical environment both shows land subsidence causes change flow pattern,...
This paper proposes to identify the variation of accessibility healthcare facilities based on vulnerability assessments floods by using open source data. The data comprises Open Street Map (OSM), world population, and statistical analysis is more focused vulnerable populations that might be affected floods. Therefore, a assessment conducted beforehand location where population located. A before after scenario applied evaluate changes accessibility. GIS Network Analyst chosen as tool. results...
Landslide, one of the most disastrous natural hazards, causes damage to infrastructure worldwide and local communities. Pacitan, Indonesia is city with high susceptibility landslides occurrence. The conditions landslide occurrence are assumed be same in future. This study’s objective produce a map by using machine learning methods based on topographical factors including elevation, slope, aspect, profile curvature, plan Topographic Wetness Index (TWI), distance river, geological as...
Abstract Landslides are disasters that cause huge losses to both human life and infrastructure. Therefore, this research purpose of carrying out landslide susceptibility spatial modelling using a random forest (RF) algorithm. This uses 12 conditioning factors generate map, which comprises elevation, slope, aspect, soil type, geological distance river, NDVI (Normalized Different Index), river density, TWI (Topographic Wetness annual rainfall, land use. Each model was evaluated by 9 parameters...
Abstract A series of floods occurred in the early year 2021 are first major South Kalimantan flood past fifty years. The regions which were affected by them Banjarmasin, Central Hulu Sungai Regency, and Tanah Laut. There 211,670 people severely flooding some need to be evacuated higher zones. Not only as a concern Indonesia National Disaster Management Authority (BNPB) but also earthquake that struck Mamuju Majene province West Sulawesi on 14 15 January 2021. Damage was reported 4 regencies...
Several techniques have been proposed to observe long-term land surface deformation using phase information of synthetic aperture radar (SAR), for example, interferometric SAR (InSAR), differential (DInSAR), permanent scatterer (PS-InSAR), and small baseline subset (SBAS) images JERS-1, ALOS-1/2, ENVISAT, ERS-1/2, RADARSAT-1/2, TerraSAR-X, SENTINEL-1A/B, so on. These methods also employed investigate the impact caused by hot mudflow accident at study area regency Sidoarjo, East Java...
Bangka Belitung Archipelago is a province consisting of many islands and coastal areas, including mangrove ecosystems. Mangrove forests have experienced decline since the 1990s due to land clearing for mining. However, there was restoration replanting in 2000s. Based on these problems, this research aims identify changes area that occurred 1990 - 2020 Islands. For purpose, multi-source remote sensing data used (Landsat 5, Landsat 7, 8), machine learning random forest, free cloud-based...
Landslides pose threats not only to infrastructure around the world but also local communities. One particularly susceptible area in Taiwan is Zhoukou River basin, Kaoping watershed. source plays an important role landslide occurrence, where triggering stage initiates failure. The conditions of are assumed be same future. This study aimed produce a Random Forest model that accurately predicts future release this by validating predictions against those observed releases region. data were...
COVID-19 or Coronavirus Disease 2019 has become a global pandemic until several countries have implemented social distancing in restrictions on human activities. The Indonesian Government, early 2020, set PSBB (Large-Scale Social Restriction) policy. Still, as the Pandemic progressed, Government finally changed and PPKM (Enforcement of Community Activity Restrictions) an impact decreasing industrial On other hand, this will be beneficial due to decrease air pollutants. Pollutants come from...
Perkembangan Sistem Informasi Geografis dan penginderaan jauh memberikan manfaat di berbagai bidang, salah satunya adalah kebencanaan. Banjir merupakan bencana yang rawan terjadi negara-negara tropis memiliki curah hujan tinggi. Kabupaten Sidoarjo mengalami genangan banjir hampir setiap tahun. Pemanfaatan SIG dapat meminimalkan dampak banjir. Peta bertujuan untuk memetakan wilayah berpotensi dengan menerapkan metode skoring pembobotan parameter-parameter penyebab terjadinya Penginderaan bisa...
Surabaya City is the second-largest city based on population in Indonesia that affected by development of urban planning city. The areas increase socio-economic and peri-urban demographics but often took over land or green open spaces. It an unavoidable possibility air pollution due to imbalance between oxygen producers existing users. necessary calculate prediction space requirements using Gerarkis Method, which predicts spaces demand number residents, motor vehicles, livestock, industrial...
Dalam kegiatan penambangan memerlukan perhitungan volume galian. Untuk mengetahui angka produksi, dilakukan progress setiap per bulannya. Perhitungan diolah dengan 3D Modelling menggunakan sebuah software pertambangan. galian memiliki permasalahan yang kompleks serta akan sangat berpengaruh terhadap cadangan sumberdaya batubara, oleh karena itu harus seteliti mungkin agar tidak ada dirugikan. Penelitian ini mencoba mengkaji teknik gridding hasilnya dibandingkan hasil diangkut dump truck....
Abstract Landsat 8 Satellite Imagery (Landsat Data Continuity Mission, LDCM) is a satellite product made by Orbital Science Corporation, which launched with The Operational Land Imager (OLI) and Thermal Infrared Sensor (TIRS) instruments as the latest features. One of called Band 10, that provide temperature information on earth’s surface. As many research conduct comparison between imagery analysis land cover has been come positive correlation for both variable. to prove relationship, it...
