Abstract

Excavation work is a type of work that is commonly found in many construction projects. In carrying out excavation work, it is necessary to consider stable slope conditions so that landslides do not occur during work. Common ground excavation work found on Bangka Island, especially in the city of Pangkalpinang, is kulong excavation, or sea excavation, as an effort to increase depth elevation. This study aims to determine changes in soil slope stability due to excavation work at a certain depth and slope. The study used field observation data in the form of CPT (Cone Penetration Test), hand drill, and data from laboratory analysis. Data analysis was then carried out using the Slope/W software, which is part of Geostudio 2018, to determine the safety factor for soil slopes using the Bishop and Fellenius method. The value of the safety factor produced by Slope/W determines the level of stability of the soil slope. The slope of the soil varied 15⁰, 30⁰, and 45⁰ and the excavation depth was determined to be 4 m and 8 m. The results showed that the safety factor of the 4 m and 8 m excavation depth in the same slope angle was decreasing about 23.18 % while the safety factor of the 15⁰ and 30⁰ excavation slope in the same depth was decreasing about 31.81%

Abstract

Erosion is one of the exogenic processes that commonly occur around river dynamics. Intensive erosion occurs at the riverbank area, which has the potential to cause the slope on that side to collapse. Therefore, a groyne-type structure is required to prevent this from happening. A groyne-type structure is planned to reduce the impact of erosion in the Pelangai River with embankment. This research aims to determine the stability of the groyne with embankment design using Plaxis 2D software. Plaxis 2D modeling uses soil input parameters based on CPT, SPT, and groyne structure with approximation parameters. The modeling results show that with the addition of groyne, embankment and traffic load, the safety number drops from 1.906 to 1.241. This figure does not meet the safe number limit according to SNI Geotechnical 8460 of 2017, which requires a minimum safe number of 1.25. In addition, the addition of groyne, embankment, and traffic load resulted in soil settlement of up to 6.3 cm, which is still considered safe.

Abstract

Soil liquefaction is important in geotechnical engineering, particularly in seismically active areas like Indonesia and New Zealand. With an emphasis on publications written by researchers from Indonesia and New Zealand between 2015 - 2025, This research is a bibliometric analysis that uses data from the Scopus database and the VOS viewer application to assist in interpreting the gathered bibliometric data. The author from New Zealand (Misko Cubrinovski) seems to be the most productive in researching and writing related to soil liquefaction, with 48 articles. Authors from Indonesia are relatively more evenly distributed, with 10-20 articles dominated by Sito Ismanti, Lindung Zalbuin Mase, and Teuku Faisal Fathani. In addition, compared to Indonesian institutions, New Zealand institutions are more likely to collaborate with external parties such as the United States (University of California, University of Texas, University of Washington, etc.), enabling them to obtain greater funding to encourage research productivity. The research map used Scopus RIS data showing three clusters: red (general liquefaction terms), blue (New Zealand-focused, e.g., CPT and shear waves), and green (Indonesia-focused, e.g., seismic response). Minor clusters (purple, yellow) link related topics.
