Abstract

This study investigates the slope stability of andesite quarries from a geotechnical and civil engineering perspective, emphasizing geological, geotechnical, and civil engineering factors influencing stability and their implications for mining and infrastructure operations. Andesite is widely used as an aggregate material in construction due to its compliance with Indonesian National Standards (SNI) for aggregate quality. Through comprehensive geotechnical assessments and slope stability analyses, the research concludes that the Andesite quarry slopes exhibit high levels of stability, supporting safe mining practices. Calculated Factor of Safety (FS) values consistently exceed safety thresholds, indicating favorable conditions for resource extraction. Slope simulations using Slide and Geoslope applications confirm the robustness of the slopes, with Safety Factor (FS) values ranging from 1.601 to 2.614. The implementation of open-cut methods, supported by meticulous slope design and blasting techniques, enhances safety and efficiency in mining operations. The study underscores the feasibility and safety of mining activities in the researched area, contributing to the advancement of mining engineering practices in volcaniclastic environments. Effective slope management strategies are essential for ensuring sustainable resource extraction while prioritizing worker safety and environmental integrity.

Abstract

The research area is along the Riau - West Sumater highway KM 82 - 89 where landslides are very common. The factors most often discussed are rainfall intensity, degree of slope, geological structure and the presence of plants. In this research, the factor of the presence of clay is the main focus in its influence on the occurrence of landslides. Landslide sampling is carried out at landslide locations. Soil samples were also carried out in laboratory simulations of the process of landslides. The methods used to identify the type of clay are Scanning Electron Microscope (SEM) and X-ray diffraction analysis (XRD). The results of the analysis showed that all of the 3 soil samples analyzed using SEM showed the presence of Kaolinite, Montmorillonite and Illite types of clay. In terms of the percentage of clay presence based on XRD analysis at 3 stations, it shows the presence of Kaolinite clay in each soil sample with the percentage of ST1, ST2 and ST3 Kaolinite presence are 29.55%, 18.33% and 36.67%. The presence of Montmorillonite and Illite is indicated by the presence of the mineral Muscovite from the SEM analysis results where its presence is only found in ST1 and ST2 with percentages of 34.85% and 26.67%. The implication of the presence of Montmorillonite and Illite clay is an important factor in the occurrence of landslides, especially the size of the landslide that occurs. This is shown by the linearity between the percentage of Montmorillonite and Illite presence and the distance of the landslide that occurred in the simulation results.

Abstract

Bukit Pelintung is a part of the Pematang formation exposed at the surface. Bukit Pelintung has different lithology with the area surround it, where the area surround Bukit Pelintung consists of old and young superficial deposit with peat, clay and silt lithology. Bukit Pelintung is a part of the Pelintung village, subdistrictMedangKampai, Dumai city located in the northeastern city of Dumai. The total area of Bukit Pelintung is about 36km2. Silica sand in Bukit Pelintung associated with iron (Fe2O3) sand and alumina (Al2O3) sand and characterized by different colors of sand. Four-point location of the research area that has been conducted in Bukit Pelintung showed a high silica content. Laboratory test using the X-RF (X-Ray Fluorescence) method showed the compound silica (SiO2) has a high percentage above 95%.

Abstract

Rock mass characterization study at the Kajang Rock quarry wasper formed with the use of refraction seismic method. Rock Quality Designation (RQD) can be measured in the field. Discontinuity survey and processing of seismic data determined from 4 locations have been examined in this site. Based on refraction seismic method, velocity of P waves (Vp) can be obtained, and the weathering grade of rock mass has been determined. Location 1 consist of 5 weathering zone with the range of Vp of 200-5400 m/s. Location 2 consist of 4 weathering zone with the Vp range of 600-5600 m/s. Location 3 consist of 4 weathering zone with range of Vp of 800-5250 m/s. Location 4consist of 5 weathering grade with the range of Vp of 250-5000m/s. Rock Quality Designation (RQD) Location 1 shows the rock is excellent (98.63%), in Location 2, RQD shows the rock is good(98.38%), in Location 3 RQD shows the rock is excellent (99.03%), in Location 4 RQD shows the rock is excellent (96.43%).

Abstract

Universitas Islam Riau merupakan salah satu universitas tertua yang ada di kota Pekanbaru. Kebutuhan air bersih terus meningkat seiring perkembangan universitas ini. Sebelumnya, pengeboran airtanah gagal dilakukan, karena pekerjaan tidak diawali dengan identifikasi kondisi geologi bawah permukaan. Penelitian ini bertujuan untuk mengetahui kondisi geologi bawah permukaan agar dapat ditentukan lokasi pengeboran airtanah yang sesuai. Metode yang digunakan adalah metode Electrical Resistivity Imaging (ERI) dengan menggunakan Geocis Resistvity meter multi elektroda (32 elektroda), pengeboran airtanah untuk mendapatkan airtanah sekaligus log stratigrafi bawah permukaan dan persampelan airtanah untuk pengujian kualitas airtanah menggunakan peralatan YSI-Pro. Hasil analisis ERI didapatkan lapisan akuifer berada pada kedalaman 20 – 75 meter dengan nilai resistivitas 8456 – 87532 Ωm yang diinterpretasikan sebagai lapisan pasir.  Hal ini dikonfirmasi dengan pengeboran yang menunjukkan bahwa di bawah permukaan didominasi oleh pasir halus berdasarkan hasil analisis granulometri. Selain itu, interpretasi ERI mampu mengidentifikasi penyebab kegagalan pengeboran sebelumnya. Kegagalan disebabkan terdapatnya bongkah batuan pada kedalaman 15 meter dengan geometri membulat. Nilai resistivitas bongkah tersebut masuk dalam kategori resistivitas tinggi yaitu >87532 Ωm. Kondisi airtanah yang didapatkan mempunyai kualitas yang baik dengan indikator warna jernih, tidak berbau, rasa tawar, temperatur 27°C, pH netral (6.55), konduktivitas 0.0461 µs/cm, dan zat padat terlarut 28.5 mg/L.
