Java Island holds the highest record of landslide events in Indonesia. In 2021, the Bogor area, consisting of the city and regency of Bogor, recorded the highest number of landslides. These events further impact the fatalities, damage, and loss to society. Landslide mitigation should be considered to reduce the risk caused by landslide hazards. In...

Within the concept of disaster risk, vulnerability is one of the key determinants. It acknowledges the degree of unsafe conditions in a susceptible zone so that mitigation measures and disaster resilience can be enforced. Bogor area is the most susceptible region to landslides with more than 485 landslide events since 2012. However, there is still...

Landslide is one of the most highly frequent natural hazards that can bring serious casualties. One of the most susceptible landslide regions in Indonesia is Bogor area (the Regency and City of Bogor), which records the highest landslide events in the Province of West Java, Indonesia. An assessment of landslide susceptibility is one of the mitigati...

Landslides in geothermal areas are one of the environmental challenges that are attributed to their volcanic and hydrothermal systems. However, the inventory of landslides in geothermal areas remains considerably limited. This may implicate pitfalls, where characterisation of historical events is an essential practice in disaster risk management. A...

Sigi Biromaru is near Palu City; both experienced the Palu earthquake on 28 September 2018. Unlike Palu City, a flat area, Sigi Biromaru is hilly, so it experienced landslides after the big earthquake. This study performed landslide susceptibility mapping for Sigi Biromaru using a machine learning method, namely random forest. Nine parameters were...

A catastrophic Palu earthquake on September 28 th , 2018 with Mw 7.5 triggered countless slope failures, generating numerous landslides. This paper presents a practical method for susceptibility assessment of earthquake-induced landslides in the Palu region and the surrounding area. The statistical weight of evidence (WoE) model was used to assess...

The main purpose of this paper is to compare the performance of bivariate statistical models i.e. Frequency Ratio, Weight of Evidence, and Information Value for landslide susceptibility assessment. These models were applied in Cianjur Regency, West Java Province (Indonesia), in order to map the landslide susceptibility and to rate the importance of...

Abstract Landslides are common natural disasters in Bogor, Indonesia, triggered by a combination of factors including slope aspect, soil type and bedrock lithology, land cover and land use, and hydrologic conditions. In the Bogor area, slopes with volcanic lithologies are more susceptible to failure. GIS mapping and analysis using a Frequency Ratio...

Metode validasi dalam pemodelan kerentanan gerakan tanah merupakan tahap yang sangat penting, karena terkait keakuratan data yang dipakai dan uji hasil pemodelannya. Makalah ini menyajikan dua jenis metode validasi terhadap penilaian kerentanan gerakan tanah secara statistik, dengan studi kasus di Kabupaten Ciamis. Sejumlah 133 kejadian gerakan tan...

ABSTRAKPeta kerentanan gerakan tanah sangat diperlukan sebagai dasar dalam perencanaan tata ruang, pemanfaatan lahan dan mitigasi bencana. Kerentanan gerakan tanah dipengaruhi oleh beberapa faktor seperti kemiringan lereng, arah lereng, litologi, tutupan lahan, elevasi, curah hujan, kelurusan, percepatan gempabumi, kurvatur, arah aliran, jarak dari...

Bandar Lampung merupakan wilayah perkotaan padat penduduk yang terdiri atas daratan dan perairan dengan beberapa dataran tinggi dan perbukitan yang terbentang di wilayah Kota Bandar Lampung. Kepadatan penduduk yang didukung dengan pembangunan infrastruktur yang tinggi membuat Kota Bandar Lampung menjadi kota dengan pertumbuhan yang pesat. Untuk men...

Landslide susceptibility map is an imperative basic tool for land use application, spatial planning and disaster mitigation. In this paper, a statistical method called the Weights of Evidence (WoE) was applied to characterize landslide-prone areas in landslide susceptibility map. The WoE model was applied in order to select the main causative facto...

This paper assesses based on area under the ROC curve (AUC) for the highest causative factors extraction for landslide susceptibility mapping in the Takengon, Central Aceh, Indonesia. To test the applicability of AUC, a landslide inventory map was split into two subsets: (i) 70% of the landslides in the inventory to be used for modelling/training d...

Takengon is an area prone to earthquake disaster and landslide. On July 2, 2013, Central Aceh earthquake has induced large numbers of landslides in Takengon area, which resulted in casualities of 39 people. This location was chosen to assess the landslide susceptibility of Takengon, using a statistical method, referred to as the weight of evidence...

Landslides in Indonesia cause severe disasters, significantly in populated areas and their vicinities. Landslide susceptibility assessment (LSA) is a vital tool for its mitigation. In this study, a bivariate statistical method called the Weights of Evidence (WoE) was applied to characterize landslide-prone areas on a landslide susceptibility map. T...

The Jemblung landslide in Banjarnegara, Indonesia was one of the most destructive landslides in the country since 2006. This landslide caused at least 90 deaths while more than 1300 people were evacuated to safer areas. Concerning the failure mechanisms and type of material, the event can be characterized as a complex landslide (earth slide to eart...

The Banjarnegara landslide was one of the worst and deadliest landslides in Indonesia since 2006. Landslide victims of Banjarnegara reached 95 people, 13 people were missing, and 1308 of people were evacuated to safer places. We complemented the existing geological, geomorphological and geotechnical database by our field data, in order to enhance t...
