Abstract

Infrastructure development on KIPP-IKN East Kalimantan area faces challenges such as flooding and unavailability of raw water. To address these issues, a Retarding basin is being built to address these issues. However, the engineering geological conditions on the basin and surrounding area can vary significantly, impacting the construction process. Further research is needed to understand these conditions and safety factors for slope stability and seepage in the main dam building. The research method used is the surface and subsurface geological mapping method to analyze engineering geological conditions as well as simulating the stability of the main dam using data from laboratory analysis. The research area consists of residual soil classified as Class D and mudstone as Class Middle, with fair-poor quality rocks. Slope stability simulations show that the area meets minimum requirements and is safe from landslides. Additionally, seepage stability simulations show that the TR-01 retarding basin's seepage discharge is below maximum permitted discharge requirements and is included in the safe category.

Abstract

The Masamba area of North Luwu Regency has been hit by a flash flood disaster on July 13, 2020. The flash flood claimed dozens of lives, hundreds of people were injured and thousands of houses were submerged. Based on the analysis of several information, the cause of the flash flood in Masamba was due to high rainfall and landslides that occurred in the upstream area. Land movement vulnerability zoning is needed in this area to provide information in making disaster mitigation policies for post-disaster planning and development. Frequency Ratio and Weight of Evidence methods were applied in this study by using parameters such as: slope, lithology, land cover, rainfall, slope direction, slope convexity, distance from river, distance from fault and soil type. The Weight of Evidence method provides more accurate results with an accuracy rate of 99.83%. Vulnerability zoning of landslides in the Masamba area are grouped into 5 classes; The zone of vulnerability to soil movement is very high, around 6,822.27 ha or about 25.47% of the research area. The high ground movement vulnerability zone is about 4261.84 ha or about 15.91% of the research area.

Abstract

The tropical climate condition of Baubau City which is located at 5°21'- 5°30' South Latitude 122°30' - 122°45' East Longitude causes the Kota Baubau Region which describes the tropics to experience more intensive weathering. Most of the landslides that occurred in Baubau City were in areas with unstable geological conditions and were often triggered by heavy rains that exceeded the highest point. This study aims to determine the causes of landslides, types of landslides, and countermeasures. In this study, measurements of slope geometry were carried out which included slope height and slope angle, testing rock and soil samples at the research station, as well as observing other supporting factors. The results of the study show that 3 stations have avalanche-prone zones. The causes of landslides are slopes with a slope angle of > 400 at station 1 of 530, station 2 of 410 and station 3 of 610, rainfall in the study area reaches the highest point of 714 MM, human activities such as dredging under the slope and construction of shaft roads cause slope instability and cause hazards such as landslides and vibrations. The types of avalanches at stations 1 and 2 are avalanches, while at station 3 the slides and falls are viewed from the geometry of the slopes processed by Autocad, the appearance of the research station and the results of the geostudio simulation show the shape of the slip plane with a FoS value of <1.07. Based on the results of research at 3 research station points, there is a potential for landslides to occur. The countermeasures methods used are structural mitigation, building of cliff reinforcement walls, surface soil stripping and increasing slope stability, namely changing the slope geometry. Non-structural mitigation, namely by providing information to the BPBD and the community regarding landslides.

Abstract

Slope stability assessment is essential in open discharge designs to prevent failure during discharge operations. This study investigated the safety factors of the disposal slope to determine the safe disposal sequence distance at Disposal X, Sorowako, South Sulawesi, Indonesia. Stability evaluation was carried out using the Limit Equilibrium Method with the Morgenstern–Price formulation at GeoStudio SLOPE/W 2022. The analysis incorporates slope geometry, laboratory-tested geotechnical parameters, equipment-induced soil pressure, and topographic data. Three representative cross-sections were analyzed to identify critical conditions. Preliminary results show that the calculated safety factor is below the minimum regulatory requirement of 1.3. Therefore, design adjustments are applied by modifying the elevation of the slope sequence and controlling the discharge distance. After the redesign, the safety factor increased to 1,360, 1,362, and 1,374, indicating stable conditions. The optimized configuration meets regulatory standards and provides a reliable technical reference for safe disposal operations in the disposal area.

Abstract

The Mamampang area is composed of the rocks of the Lompobattang Volcano with the dominance of tufa lithology which is fragile and easily weathered. Morphologically, the study area shows the shape of hills to mountains with steep slopes – very steep, so it has a high vulnerability to the movement of soil masses. This study aims to analyze the potential for landslides based on the parameters of the slope and the rate of rock weathering. Slope geometry measurements were carried out using geological compasses and roll meters, then analyzed with the Bermana (2006) classification, while the rate of rock weathering was determined based on the classification of Irfan and Dearman (1978). The results showed that most slopes have a slope angle between 40°–52° with a slope percentage of 50–129% (steep to very steep category), and the weathering rate is at degrees IV–VI (strong weathered to residual soil). The condition of the tufa lithology that has undergone advanced weathering, combined with steep morphology, land use on steep slopes, and intense rainfall, is the dominant factor determining slope instability. The potential for landslides in the Mamampang area is categorized as very high, so mitigation efforts based on geology engineering are needed through land use management and strengthening of slope cover vegetation.

Abstract

Administratively, the study area is located in Samburakat, Gunung Tabur District, Berau Regency, East Kalimantan Province, Indonesia. Geographically, it lies between 117°34′30″–119°33′00″ E and 02°17′30″–02°19′30″ S. This study investigates the mechanisms responsible for the formation of undulating sections on mine haul roads, identifies suitable material sources based on Unconfined Compressive Strength (UCS) values, and evaluates their economic feasibility as surface course materials for mine roads. The methodology integrates field mapping of undulating road sections, material source mapping, frequency analysis of undulating areas, rainfall observation, and lithological characterization within the pit area. Laboratory testing of the physical and mechanical properties of the identified lithologies was conducted to assess their bearing capacity and performance under wet conditions. The results demonstrate that haul road surfaces constructed using sandstone are highly susceptible to the development of undulating deformation due to meteoric water infiltration, which significantly reduces material bearing capacity. In contrast, claystone exhibits superior performance as a road surface material owing to its impermeable characteristics, higher cohesion, and greater resistance to moisture-induced degradation, thereby maintaining subgrade stability and supporting haulage loads more effectively. UCS test results indicate that PQ claystone exhibits the highest strength (13,730 kPa), followed by QR claystone (11,720 kPa) and R claystone (5,028 kPa). Sandstone shows comparatively lower performance under wet conditions despite relatively high UCS values, with QR sandstone (13,550 kPa), PQ sandstone (10,670 kPa), and R sandstone (2,940 kPa). Material extraction strategies were optimized based on proximity to haul roads and UCS values to enhance operational efficiency and economic viability. The findings confirm that claystone, particularly PQ and QR units, is the most suitable material for mine haul road surface construction in the study area The methodology integrates field mapping of undulating road sections, material source mapping, frequency analysis of undulating areas, rainfall observation, and lithological characterization within the pit area.
