Abstract

A slope is a sloping part of the ground surface that connects the higher areas with the lower areas. Slope stability relies heavily on rock mass characteristics, including the Rock Mass Rating (RMR) and Geological Strength Index (GSI) classifications, which are used to evaluate rock quality and slope stability. This research was conducted at the mine CV. Putra Idola which is located in Teluk Kabung Tengah Village, Bungus Teluk Kabung District, Padang City and Nagari Siguntur, XI Koto Tarusan District, Pesisir Selatan Regency, West Sumatra Province. The goal is to determine RMR and GSI values and identify potential slope instability. The methods used include geotechnical mapping with a 15.2-meter long scanline technique to identify burly structures as well as laboratory testing to obtain the physical and mechanical properties of rocks. The data obtained were analyzed to calculate the RMR and GSI values of different types of rocks at the research site. The results showed that the GSI values on the three slopes studied ranged from 53 to 75, while the RMR values ranged from 57 to 75. Based on this classification, the Fresh Andesite and Hornfels rocks are included in the "Good" category, while the Weathered Andesite rocks are included in the "Medium" (Fair) category. The results of this study provide important information for the mining industry in efforts to mitigate landslide risk and design safer slope designs. In addition, this study also emphasizes the importance of rock mass classification analysis in the evaluation of slope stability in open pit mining activities.

Abstract

This research aims to examine the implementation of the SIAKAMA application in the Apprenticeship Industrial Program. This program was created as a SIAKAMA application to overcome hurdles during the monitoring and evaluation stages. At the monitoring stage, supervising lecturers and field supervisors can use the SIAKAMA application to monitor all Apprenticeship Industrial program student activities in the field, resulting in a good and smooth communication and coordination system. At the evaluation stage, the supervising lecturer and field supervisors in the SIAKAMA application can conduct assessments based on student activities in the field, including daily evaluations and final assessments after the Apprenticeship Industrial Program has been finished. This study employs a quantitative descriptive technique, the Research & Development method, and the 4D development model. A sample of Apprenticeship Industrial Program students from five departments of the Faculty of Engineering, Padang State University, was used in this study. The SIAKAMA application was found to be valid with a value of 0.876, practical with a value of 78.67, and effective with a value of 81.22% after data analysis using SPSS 25. This suggests that implementing the SIAKAMA application to enhance the work competency of Apprenticeship Industrial Program students is viable. The Apprenticeship Industrial Program model represents a modification of the Three Set of Actor development model, yet it hasn't been incorporated with the Industrial Revolution 4.0. Engaging in this Program enables students to acquire 4C skills, including Creativity and Innovation, Critical Thinking and Problem Solving, Communication, and Collaboration.

Abstract

One important aspect of open pit mine planning is slope geometry design, which affects the stability of the slope and the efficiency of overburden removal. This study aims to investigate the influence of vertical bench position and bench width on slope stability and their effect on stripping volume. The limit equilibrium method was used for slope stability analysis, with the assistance of Rocscience Slide2 software. The stripping volume estimate was obtained from pit shell simulations using GEOVIA Surpac software. The vertical bench positions analyzed were ¼, ½, and ¾ of the total slope height, which was 60 m. The bench width variations tested were 0, 5, 10, 15, 20, and 25 m, while maintaining a minimum safety factor requirement of 1,3. The analysis indicated that the optimal configuration is achieved by placing the bench at the vertical position of ½ of the overall slope height with a bench width of 10 m, which results in an overall slope angle of 44°. The result is steeper than the no-bench scenario, with an overall slope angle of 42°. This geometry produces an estimated overburden volume of 195,123,000 m3, which is smaller than the no-bench scenario of 196,559,500 m3. Therefore, the reduction in stripping volume is 1,436,500 m3 or approximately 0.73%. This study shows that optimizing the bench configuration enables the implementation of steeper overall slope angles while reducing the required stripping volume in open pit mine planning.
