This geological assessment is carried out to identify the potential hazards of landslides in the surrounding area and efforts to overcome them. This research is focused on Keban Agung and its surroundings, Kikim Selatan District, Lahat Regency, South Sumatra Province. This was done because landslides had occurred in the Keban Agung area. The method used is the Analytical Hierarchy Process or of…
The research is located in the Tanjung Agung area, including the Sumatra Selatan Basin, with active tectonic conditions. Research at this location is intended to identify the level of tectonic activity using a quantitative geomorphological approach carried out in the Batang Empu and Batang Leko sub-watershed. The parameters used in this study include Drainage Density (Dd), Asymmetry Factor (AF)…

Daerah ini termasuk ke dalam Cekungan Bengkulu dengan kondisi tektonik yang masih aktif. Penelitian ini bertujuan untuk mengidentifikasi dan memperoleh data tingkat aktivitas tektonik dengan menggunakan pendekatan geomorfologi kuantitatif. Parameter morfometri yang digunakan yaitu …
Secara geografis daerah penelitian terletak di Kecamatan Bruno, Kabupaten Purworejo, Jawa Tengah. Daerah ini termasuk ke dalam Zona Serayu Selatan, dimana aktivitas tektonik pada zona ini berlangsung intensif pada periode tectonic quiescence Pliosen. Penelitian ini bertujuan untuk mengevaluasi dan memperoleh data tingkat aktivitas tektonik terhadap jalur sesar kemudian dikaitkan dengan faktor b…
The research location is in the Puspahiang area, Tasikmal aya Regency, West Java, where most of the Tasikmalaya area consists of moderate plains with an altitude of 250 to 750 meters, and the level of vulnerability to ground movement is quite high (BPS Tasikmalaya 2021). Observations in the research area were carried out by taking soil samples for testing the type of soil that occurred at the l…
Jambi City is one of the fastest-growing cities in Indonesia and the capital city of Jambi Province. The population is experiencing a very rapid increase every year. The population is accompanied by increased infrastructure development and groundwater needs. Geologically the area of Jambi City is formed from geological formations that are a quarter of the age that is still young, so it is possi…
Liquefaction and landslide can occur during earthquakes caused by changes in soil saturation levels so that the soil loses strength due to loss of tension between grains. One of the determinations of soil moisture data using satellite imagery analysis is Landsat. Landsat has provided moderate, global, synoptic spatial resolution and repeated earth's soil surface coverage. This paper discusses t…
Penelitian tugas akhir menggunakan metode Sistem Informasi Geografis dan overlay yang dilakukan di desa Taratak Bancah dan sekitarnya Kecamatan Silungkang, Kota Sawahlunto, Provinsi Sumatera Barat. Berdasarkan data Badan Nasional Penanggulangan Bencana (BNPB) daerah penelitian memiliki indeks terhadap bencana tanah longsor (sedang 0,3 – 0,6). Penelitian ini merupakan studi lanjutan dari pemet…
The research area is located in Banjarpanepen, Banyumas Regency, Central Java. The research area has a morphologu of lowlands to high hills with sloping to very steep slopes so that several landslide point were encountered during field observation. The research was conducted using the fuzzy logic method in order to cover a large area in a short time using a quantitative approach with simple com…
Menurut Badan Pusat Statistik (BPS) Provinsi Sumatera Barat, terdapat 30 kejadian tanah longsor di Kabupaten Lima Puluh Kota dari tahun 2019 hingga 2021 Penelitian yang dilakukan merupakan analisis kerawanan longsor di Desa Lubuak Alai dan sekitarnya, Kecamatan Kapur IX, Kabupaten Lima Puluh Kota, Sumatera Barat. Penelitian ini bertujuan untuk mengidentifikasi kondisi geologi dan tipe longsor, …
Based on data from the National Disaster Management Agency (BNPB), Gunuang Malintang Village, Limapuluh Kota Regency, West Sumatra Province is one of the areas experiencing the impact of landslides due to various triggering factors. Therefore, it is important to map the vulnerability of landslides and analyze the level of vulnerability using the fuzzy logic method in order to reduce the impact …
The research area is located in Cihea and its surroundings, Cianjur Regency, West Java. The morphology of the area consists of hills and high hills which the slopes are dominated by very steep slopes, especially on several main roads. In several locations, landslides were found during field observations which hindered access to the main road to the village. Research on landslide susceptibility …
The location of this research is in the Muaro Region, Sijunjung District, Sijunjung Regency, West Sumatra Province. The research area has a high morphology with unstable slope conditions and steep slope conditions so that this situation is one of the factors causing landslides in the study area. The research was conducted using field observation methods to obtain evidence of landslides that occ…
