Abstract

Underground mining activities (Undergound Mining) at PT Allied Indo Coal Jaya Encroachment area, Sawahlunto City has the risk of subsidence due to reduced soil carrying capacity due to excavation of underground mine openings. The excavation of underground mine openings will result in disruption of the stability of the area such as roof collapse, rib spalling, and floor heave. This research was conducted in 2 research locations, namely Tunnel 6 Seam B and Tunnel 3 Seam C which aims to determine the recommendation of a buffer system in underground mine openings (Tunnel) by analyzing the geomechanical value of rocks using the Rock Tunnelling Quality Index (Q-System) method. ) so that the Strength Factor value increases. Data collection methods were carried out by field observation and laboratory testing, while data processing used Phase 8.0 software with Mohr-Coulomb failure criteria. The results of calculations and data processing showed that the Strength Factor value in Tunnel 6 Seam B was 1,04 (relatively stable) and Tunnel 3 Seam C was 0,84 (unstable). These results indicate that Tunnel 6 Seam B and Tunnel 3 Seam C must be supported by a buffer system. After the buffering system was carried out the Strength Factor value of Tunnel 6 Seam B increased to 1,59 (stable) and Tunnel 3 Seam C increased to 1,63 (stable).

Abstract

Sukamoro area, Banyuasin Regency, South Sumatera, was the research location. This investigation focuses on the origin of sandstones from the Talang Akar Formation. In the area of investigation, sandstones are widely dispersed and exhibit a variety of properties. Due to the abundance of sandstones found and their high resistance and physical compactness, an analysis of the original rock can be carried out. Generally, the material that makes up sandstone comes from the previous rock. This investigation was undertaken using a descriptive-analytical methodology to determine the origin of the rock. The collected surface data is subsequently petrographically examined. After determining the composition of the constituent minerals, a provenance analysis was conducted to determine that the Talang Akar Formation's sandstones originated from the Magmatic Arc. Furthermore, the Talang Akar sandstone reveals the origin of the Recycle Orogen. Thus, it is considered that the sandstones of the Talang Akar Formation have seen many uplift episodes as a result of tectonic activity, almost to the point where they have experienced an increase in the maturity or stability of their continental block provenances

Abstract

Flood is a natural disaster with an intensity that often occurs in cities on a scale with excess water discharge in some areas. This research was conducted to determine the risk of flooding in Mekarsari Village and its surroundings, Cianjur Regency, West Java. (According to InaRisk, 2022) Risk and danger of flooding Moderate – High. This study uses data for the entire year 2022. With several parameters used in this study including land cover, rainfall, soil type, slope, NDVI, NDWI and SAVI. Simple Additive Weighting or weighting for each parameter with different results, according to the classification of each of these parameters. The results of this weighting will become a Flood Hazard Risk Map which was previously the result of overlay and intersection of land cover map, rainfall map, soil type map, slope map, Normalized Difference Vegetation Index map, Normalized Difference Water Index map and Soil Adjusted Vegetation Index map. On the Flood Disaster Risk Map there are five categories of vulnerability levels Not Hazardous, Less Hazardous, Moderate, Hazardous and Very Hazardous. The cause of the risk of flooding in the study area is that most of the land use is diverted to rice fields, plantations, dry agricultural land and settlements so that the lack of vacant land causes low absorption of rainwater and also steep slopes and high elevations which also cause rainwater to be stored in the lowlands. settlements) with moderate to high rainfall intensity every month. There is also a lack of education for the community to mitigate the risk of flood disasters so that waste management and waterways in settlements are inadequate and well managed.

Abstract

The geological setting in the area is a strong attraction for natural tourism. The Sawahlunto Geopark area is one of the Geoparks located in West Sumatra Province which has a variety of geological sites. This area meets the criteria that make it a potential Geopark. The purpose of this analysis is to evaluate the potential of geotourism and use this assessment as a basis for developing geotourism in the Sawahlunto and surrounding geotourism areas. This analytical study was carried out using the M-GAM (Modified Geosite Assessment Model) method. In the study process, research methods were carried out using questionnaire data based on 27 indicators from the M-GAM method.M-GAM method has 27 indicators consisting of main and additional values that will be used as a questionnaire which will produce quantitative results. The 27 indicators contain several geotourism assessments, including scientific value, aesthetic value, protection value, functional value, and tourism value of a geosite. The maximum score that can be obtained by a geosite that has all the perfect criteria in 27 indicators will get a main score of 12 and an additional score of 15. 7 geosites will be assessed with results, namely Batu Runciang (8.17 and 7.62), Serpih Bakelok (6.35 and 7.72), Tabiang Tinggi (6.81 and 8.14) and Puncak Cemara (8.19 and 8.41), Stone Garden (6.37 and 7.96), Batu Gantuang Cave (3.91 and 6.07) and Kubang Waterfall (3.48 and 6.48). Referring to the results of the Sawahlunto geosite assessment, it was concluded that the Batu Runciang and Puncak Cemara Geosites had a high value in terms of main values compared to the other 5 geosites. Meanwhile, for additional value, Tabiang Tinggi and Puncak Cemara have sufficient value compared to the other 5 Geosites. This is because geosites with low value still lack various things such as facilities and promotions. Efforts that can be made are to build facilities at several geosites that still experience a lack of public facilities. Apart from that, promotion on social media is also very helpful in introducing geosites to the public.

Abstract

Landslides are a natural process that occurs in a natural landscape on earth which can cause various environmental damage and can cause loss of life. An increase in the risk of landslides can be caused by uncontrolled land conversion due to the increasing population so that land development is necessary. The research was conducted in Luhurjaya and surrounding areas, Cipanas District, Lebak Regency, Banten with an area of 9 x 9 km. The spatial integration method was used to map landslide-prone zones using a scoring and weighting method, using five parameters, namely slope, rainfall, lineament density, rock type, and NDVI. Those five parameters are then overlaid to form a landslide susceptibility map. As a result of analyzing the research area based on these five parameters, it was found that this area has five slope classes, one rainfall class, five lineament density classes, three rock type classes, and four NDVI classes. After all the datas are scored and weighed, it was found that this research area can be classified to three zones, namely low landslide susceptibility zone, medium landslide susceptibility zone, and high landslide susceptibility zone. From the results of this analysis, disaster mitigation should be needed that can affect the community in the Lebak Regency area, Banten Province, namely in the form of providing provisions in the form of knowledge to the community regarding disaster management which is useful for minimizing the risk of the consequences of landslides
