Abstract

Stabilitas lereng merupakan faktor utama yang harus diperhatikan dalam kegiatan perencanaan pembangunan PT. Virama Karya yang terletak pada kecamata Jatiyoso, di karenakan dapat mengganggu kelancaran pembangunan dan dapat membahayakan keselamatan pekerja hal – hal yang dapat menyebabkan leren tidak stabil antara lain yaitu gempa bumi, struktur geologi, peledakan, dan material batuan penyusun lereng, pada penelitian ini dapat menggunakan metode RMR, SMR, dan GSI untuk dapat mengindentifikasikan dan memberikan rekomendasi terhadap kondisi lereng, kemudian menggunakan metode Janbu untuk mendapatkan hasil dari nilai faktor keamanan, pada penelitian ini didapatkan hasil pengukuran geometri lereng yang didapatkan dengan nilai Single Slope 50, tinggi 50 meter, lebar 80 meter, panjang jenjang Slope stability is an important factor that is considered on the bridge which is one of the accesses in the construction of hydropower at the JatiGede dam because it can interfere with the smooth transportation of materials in the construction of hydropower, things that can cause slopes to become unstable are earthquakes, geological structures, and materials. In this study, the slope compilers used the RMR and GSI methods to identify and provide recommendations for slope conditions, then used the Janbu method to obtain the safety factor value, in this study the rock mass conditions on scanlines 1 to 5 were very blocky and rough surface conditions. , weathered rock condition, the safety factor value on the slope is 0.497, and has a sliding wedge type landslide potential of 21.54%. Based on the recommendation slopes made with Slide 6.0 software in order to get a FK value> 1.25 to produce stable slope conditions and can minimize the dangers that can occur.

Abstract

The development of seismic anisotropy needs to be studied systematically hence research could be focused on the latest scientific knowledge, therefore a bibliometric analysis is needed as a measurement of citation strength in the form of mapping "co-occurrence", "co-author" and "co- citation", thus the strength of the research direction could be well understood. The software which is used; VOSviewer version 1.6.18 examined at least 494 papers in the SCOPUS domain during 2017 -2020. It appears from the results that the development of the seismic anisotropy are very rapidly dominated by the needs of the applied science and pure science. The heavily publication countries are United States of America, China and Japan. However, in reality, this density does not necessarily correspond to the number of citations between countries, as well with publications in Japan.
