PT. Indocement Tunggal Prakarsa Tbk, Citeureup District, Bogor Regency, West Java Province, is the subject of this research. By calculating the safety factor value based on the Rock Mass Rating (RMR) using the Spencer method using Rocscience Slide 6.0 software, researchers hope to ensure slope stability. In fact, based on the slope stability analysis, it has a safety factor value of 0.900, so it is not in accordance with the Minister of Energy and Mineral Resources regulation 1827/K/30/MEM/2018. Based on this, recommendations for slope analysis of the research area have been made with a safety factor value of 1.232 in accordance with applicable regulations.","PeriodicalId":288050,"journal":{"name":"Journal of Geoscience Engineering & Energy","volume":"93 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140438083","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the natural tourist object in the Geopark area with the beauty of ancient rock structures aged more than 60 million years ago is the Leuwi Kenit natural tourist destination in Pasirpanjang Village, which has a very large number of tourists, but in certain periods there are often visitor accidents. This research aims to identify hazards and risk assessment, as well as risk control from hazards, with research objects including parking areas, entrance gates, access routes, play facilities, and exit routes. The research method is a qualitative Hazard Identification and Risk Assessment and mapping of danger points, literature studies, field observations, interviews with the community, tour guides and tourist attraction guards. Based on the results of the study, there are fifteen danger points in the Leuwi Kenit tourist attraction, some of which can occur when the activity is running with a range of risk relative status, namely low to high. Risk relative high status is recorded to have dominated with seven danger points, risk relative moderate status with six danger points, and risk relative low with two danger points. According to the results of the study, there are fifteen danger points in the Leuwi Kenit tourist attraction, some of which can occur when the activity is running with a range of risk relative status, namely low to high. Risk relative high status is recorded as dominant with seven danger points, risk relative moderate status with six danger points, and risk relative low status with two danger points. The results of the risk assessment show that the risk status is included in potential hazards with high and medium hazard risk levels, management attention and control planning are needed. Alternative risk controls that can be implemented to minimize the occurrence of risk are administrative, engineering, and elimination approaches.

This causes the area to have the potential to have good water absorption, but it also has the potential to be disturbed by water absorption due to internal and external factors in the research area. For this reason, it is necessary to know the water absorption and infiltration rate in order to see the advanced conditions of the research area. In order to know this, researchers need to obtain primary data by processing in the field using a Double Ring Infiltrometer (Indonesian National Standard, 7752:2012); while secondary data were obtained from previous researchers, as well as official bodies in Indonesia. The rainfall at the nearest Citeko station per 5 years reaches more than 3000mm, namely 3168.8mm, indicating that the research area has a very high potential for rainfall. In addition, it can be concluded that the research area has a type of overburden in the form of loamy sand with flat to steep areas in 4 observation locations, while the other 5 observation locations are flat to very steep. Then, the results obtained in the Cijeruk area obtained 2 units of infiltration rate, namely sufficient infiltration rate with an infiltration rate of 0.192 m/day to 0.312 m/day and a high infiltration rate with an infiltration rate of 1.08 m/day up to 5.04 m/day. indicates that the water catchment area is classified as good.","PeriodicalId":288050,"journal":{"name":"Journal of Geoscience Engineering & Energy","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123958195","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Daerah Keban Jati termasuk pada Cekungan Busur Depan Bengkulu yang mengalami fase tektonik pembentukan cekungan busur depan secara kompleks dengan proses tektonik yang terjadi pada Pra Tersier – Kuarter. Metode analisis melibatkan peta geologi Daerah Keban Jati dan Sekitarnya, Peta Shuttle Radar Topography Mission (SRTM), dan data gravitasi bumi yang dipisahkan menjadi peta anomali gravitasi lokal dan peta Tilt Derivatives (TDR). Peta tersebut dilakukan analisis kelurusan untuk mengetahui arah kelurusan dan metode grafik anomali untuk memahami karakteristik anomali gravitasi terhadap struktur di peta geologi. Berdasarkan analisis kelurusan peta SRTM, anomali gravitasi lokal, dan TDR menunjukkan dominasi arah tenggara – barat laut dan utara – selatan. Kondisi tersebut menunjukkan arah kelurusan mirip dengan arah struktur pada peta geologi. Sedangkan pada data grafik gabungan anomali gravitasi lokal dengan TDR menunjukkan karakteristik sesar, antiklin, dan sinklin. Pada kedua anomali karakteristik sesar berada di antara grafik anomali puncak dan lembah. Sedangkan lipatan berada di area dekat dengan puncak ataupun lembah grafik anomali.
