Erosion in watershed area can be triggered by changes land use, human activities, and cause increased sedimentation, flood risk, environmental degradation, effective conservation measures are necessary to ensure its impact is reduced. To determine potential erosion hazards Sail Sub-Watershed the method used Revised Universal Soil Loss Equation (RUSLE), parameters include rainfall, soil erodibility, slope length slope, cover conservation. In addition, an analysis of permissible hazard index...

Abstract A regional development requires some analyses in terms of the constraint and potential. Constraints a need to be managed by periodic monitoring, while potentials maintained or optimally improved. The hexa-helix concept is penta-helix with addition role law regulation. Citatah area multipurpose where there limestone quarry, factories, tourist attractions, rock-climbing as territoral constraints found are landslides faults. To support potential region, infrastructures safe from...

In several studies on slope stability analysis, the FS (Factor of Safety) value plays an important role in determining meaning stability. Based landslide events, Table Bowles (1989) gives < 1.07 for usual occurrence collapse, <FS <1.25 collapse ever occurred, and FS> 1.25 events are rare. is influenced by angle (\alpha, degree), then can be modified based analysis relationship between with angle. The result soil Jatinangor Education Area found equation α = 7.2300.FS−0.474, at outside...

Bandung is a densely populated and rapidly growing city, especially in the Northern Area, with many rivers flowing through it. Infrastructure development if not taken into account geo hazard potential of river can cause disaster to occur resulting damages casualties. The inundation named "Cileuncang Flood" periodically occurred rainy season. Landslide also 2015 at Mekarsaluyu, Cimenyan Bukit Dago Selatan. This study explores phenomena that region. research objectives are to: identify...

Abstract The western part of Java is adjacent to the intersection major tectonic plates between Eurasia and Indo-Australia. This region often stricken by natural disasters due its geological setting, such as earthquakes, tsunamis, volcanic eruptions, floods, landslides. West Province with more than 40 million inhabitants most populous in Indonesia, where Sukabumi Regency southwestern this province known for frequent location earthquake. In Regency, Ciletuh-Pelabuhan Ratu Geopark has been...

Abstract Cilengkrang is a sub-village in the north of Ujung Berung and Cijambe sub-District Bandung Regency, Indonesia. It located on west Cikeruh sub-watershed. This subwatershed part greater upstream Citarum watershed. area has been developed rapidly by new settlement villa. However, available data erosion potential this less convenient. The severe problem that strong relation to flood potential. study starts with collected engineering geological from 14 samples. These samples were taken...

Dalam menentukan kemiringan desain final lereng yang dibentuk, salah satu caranya ialah dengan menggunakan metode geomekanik melalui penentuan nilai Rock Mass Rating(RMR) dan Slope Rating (SMR). Namun, dari SMR tidak diketahui faktor keamanan tersebut sehingga diperlukan analisis kestabilan lereng. Nilai keamanannya dapat menjadi acuan untuk membuat representatif. Penelitian dilakukan di tambang terbuka terdapat Kecamatan Jorong Kabupaten Tanah Laut, Provinsi Kalimantan Selatan. Daerah...

Landslides are significant geological events that can cause extensive damage to infrastructure, disrupt communities, and pose serious safety hazards. Understanding the mechanisms behind slope failures is crucial for effective risk mitigation development of engineering solutions improve stability. According data from National Disaster Management Agency (BNPB), Indonesia experienced 83 landslide January February 2024. A notable occurred in Nanggerang Village, Sukasari Sub-district, Sumedang...

Starlet-Perdana stands for Stabilisasi & Rancangbangun Lereng Terpadu – Perkuatan Dayadukung Tanah (Stabilization Design Integration of Slope Strengthening Soil Bearing Capacity). The research is carried out in the northern parts Bandung Basin at Cilengkrang and Jatinangor areas, around foot Gunung Manglayang Jatinangor. soil rock materials are from weathered volcanic rocks. Areas that have been identified as landslide-prone required some geotechnical engineering well direction environmental...

A regional development will decrease the open green space that affect less water infiltration during rainy season and causing high intensity of erosion rate. Jatinangor is a well-known new satellite city located in undulating volcanic hills as part Southeast Mt Manglayang. This area has been degraded from agricultural land into residential educational area. study aims to determine erodibility factor potential one important factors an prediction. The data were obtained by collecting several...

Abstract The Indonesian archipelago lies at triple junction between the world’s tectonic plates that have many natural disasters. Furthermore, Indonesia accross equator which result in a tropical climate (dry and rainy seasons). During season, rainfall often triggers landslides. Landslides can be identified by material type (soil, rock, or debris) movement (slide, fall, flow, combination). Landslide-prone areas influenced lithology (rock weathering), slope (geomorphology), seismic vibrations...

Batu Hijau is a gold mine which now run and managed by PT Amman Mineral Nusa Tenggara (PT AMNT) with open mining method. The located in Sekongkang District, West Sumbawa Regency - Province. geological structure aspects are interesting as objects this study, due to the condition very tight become trigger for slope failure. Slope stability one of important terms supporting pit activities. One failure indication caused structure. Geological analysis performed kinematic takes into account...

The research location is in the PPSDM Geominerba field campus. campus located Padalarang, West Java that surrounded by open-pit mining of limestone and marble. This was formed Oligo-Miocene Rajamandala Formation. objective to determine condition slopes around based on geomechanical characteristics. Based observations, slope angle area dominated steep slopes. rock hardness level hard with a ranging from 50-100 MPa. Rock Mass Rating shows good rocks. While Slope calculation show maximum...

West Block 'X' pit is one of the coal mining locations operated by Lati Mine Operation – PT Berau Coal. Administratively, located as part Regency East Kalimantan.
