Abstract

This study aims to evaluate the actual sump capacity in accommodating mine water discharge, design a sump that fits field conditions, and determine the optimal pump capacity and system at PT Satria Alam Manunggal, Telen Orbit Prima Site. The research methods include field data collection (sump condition, water discharge, and pump capacity) and supporting data (rainfall, geological maps, and pump specifications). The design rainfall was calculated using the Gumbel method with a five-year return period, while water discharge was estimated from runoff, rainfall, and groundwater inflow. The results indicate that the existing sump, with a capacity of 508 m³, is insufficient to accommodate an inflow of 1.210 m³/s. Therefore, two new sumps were designed: the West Sump with a capacity of 38,400 m³ and the East Sump with 78,281 m³. Each sump employs a DnD 150-4H pump with a discharge rate of 480 m³/hour. The West Sump pump can drain water within approximately three days, while the East Sump requires about seven days. The trapezoidal sump design was chosen for its efficiency, structural stability, and effectiveness in sediment (TSS) deposition control, maintaining levels within safe limits. In conclusion, the design of the West and East sumps is considered optimal in accommodating mine water discharge and improving the overall effectiveness of the mine drainage system.

Abstract

This study was conducted to evaluate the level of conformity between actual mining activities in March 2025 and the monthly sequence design plan at PT Tama Raya's P3000BK14 pit. The evaluation focused on geometric deviations, volume achievement, and changes in field conditions that influenced these discrepancies. The data used included the sequence design, actual topography from the TLS (Low-Scale Land Survey), and weekly production realizations. The results showed significant discrepancies between the planned and actual operations in weeks 2 and 4, primarily in the form of overcuts, undercuts, non-designed contour changes, thinning of the coal seam, and hydrological obstacles such as ponding and unstable drainage. The R2 sequence redesign in week 4 proved to improve the overburden excavation flow but did not fully restore coal access due to persistent geological and water conditions. These findings emphasize the need for more rapid topographic updates, more intensive water handling, and interdepartmental coordination to ensure better synchronization of plans and operations.

Abstract

This study was conducted at PT Satria Alam Manunggal Site TOP to analyze the effect of road geometry conditions on the performance of Scania P410-B6x4 transport equipment in overburden material transportation activities. The haul route from the front to the disposal site is 2.4 km long, with an average hauler productivity of 33 BCM/hour, while the company's target is set at 40 BCM/hour. This situation indicates an issue with the hauler's travel time when transporting overburden material from the front to the disposal site, resulting in the hauler's productivity not being achieved. The analysis was conducted by dividing the haul road into 29 segments, consisting of 27 straight segments and 7 curved segments. The minimum width of straight roads is 9.1 meters for two lanes and 5.2 meters for one lane, while for curves, the minimum width is 16.29 meters and 9.31 meters, with a maximum road gradient (grade) of 8%, as well as other elements such as curve radius, superelevation, cross slope, safety berm, and drainage channels, also affect operational comfort and safety. The objective of this study is to evaluate and provide recommendations for road geometry improvements to meet technical standards, thereby reducing travel time and increasing transportation vehicle productivity.

Abstract

Desa Ramang, yang terletak di pinggir sungai Kahayan, memiliki potensi sumber daya alam dan manusia yang besar, namun menghadapi tantangan dalam perencanaan pembangunan akibat kurangnya data infrastruktur yang akurat. Program Pengabdian Kepada Masyarakat (PKM) ini bertujuan untuk memetakan titik lokasi infrastruktur di Desa Ramang, Kabupaten Pulang Pisau, menggunakan teknologi GPS berbasis satelit. Metode pelaksanaan meliputi tiga tahap: persiapan, survei lapangan secara partisipatif dengan masyarakat, serta pengolahan dan analisis data menggunakan perangkat lunak SIG. Hasil kegiatan berhasil menghasilkan peta digital yang memetakan 15 titik infrastruktur utama yang terbagi dalam fasilitas pendidikan, kesehatan, ibadah, pemerintahan, dan lainnya. Peta ini memberikan data spasial yang akurat untuk mendukung perencanaan pembangunan, identifikasi kebutuhan perbaikan, dan pengambilan keputusan yang transparan dan partisipatif oleh pemerintah desa.

Abstract

Blasting in open pit mines aims not only to achieve optimal rock fragmentation but also to control the impact of generated ground vibration. This study aims to analyze the influence of the crush zone on Peak Particle Velocity (PPV) in blasting activities involving claystone and limestone layers. Field data were collected from 25 blasting operations with varied parameters: number of blast holes 25–160, explosive charge per hole 50–111 kg, and measurement distance 504–537 m. The recorded actual PPV ranged from 1.221 to 3.404 mm/s. Statistical analysis was performed using power regression to model the relationship between Scaled Distance and PPV. The results show a strong inverse relationship between Scaled Distance and PPV, where higher blasting energy concentration forms a more intensive crush zone as the initial source of vibration. Blasting in limestone yields relatively higher PPV compared to claystone under similar Scaled Distance conditions, due to the elastic and more brittle properties of limestone. The model's prediction accuracy reached 91.5% on average. Practically, to maintain PPV at a safe level (<3.404 mm/s), it is recommended to keep the Scaled Distance ≥ 48.82 m/kg⁰·⁵ and limit the explosive charge per hole to the range of 50–90 kg, especially in limestone. This study confirms the key role of the crush zone and rock lithology in blasting vibration mechanisms, providing a basis for optimizing safe and sustainable blasting designs.
