Abstract

This study was conducted in Kalasari Village, Salawati District, Sorong Regency, Southwest Papua, within the Contract of Work area of PT Megapura Prima Industri. The research integrated field geological observations, detailed lithological and outcrop descriptions, drill core logging and correlation, and laboratory proximate analysis to characterize coal occurrence and quality. Stratigraphic analysis indicates that the study area is composed of two principal lithological units: the Sele Claystone Unit, deposited in backswamp to swamp environments, and the Sele Sandstone Unit, representing floodplain facies. Borehole correlation reveals coal seam thicknesses ranging from 0.3 to 1.82 m, with a general westward thickening trend, reflecting microtopographic variation and peat stability during deposition. The roof and floor of the coal seams are dominantly claystone or clayey sandstone, indicating overbank flood sedimentation that facilitated peat preservation. Proximate analysis shows that the coal is low rank, characterized by calorific values of 3220–3619 kcal/kg (adb), low ash content (1.7–3.8%), very low sulfur content (0.2%), and high total moisture (32–37%). These characteristics are typical of freshwater swamp–backswamp facies within an upper delta plain depositional environment with limited clastic input. The relatively thin overburden further constrained coalification, resulting in low calorific values. Overall, the results demonstrate that coal distribution, seam thickness, and coal quality in the study area are strongly controlled by upper delta plain depositional dynamics, particularly swamp and backswamp facies that governed peat accumulation and preservation.

Abstract

This study examines the geological conditions and slope stability of segments IG1 and IG2 in the Magazine access area of the Pani Gold Project, Pohuwato Regency. The research methods include geological mapping, scanline analysis, kinematic evaluation using stereonet, and Rock Mass Rating (RMR) and Slope Mass Rating (SMR) assessments. Segment IG1 consists of volcanic breccia with an RMR value of 57 (Class III, Fair Rock) and an SMR value of 45–50 (Poor), indicating wedge failure potential. Segment IG2 is dominated by dacite with an RMR of 60 (Class III, Fair Rock) and an SMR of 55–60 (Fair–Good), showing a tendency toward toppling failure. The results suggest that IG2 is relatively more stable than IG1, although localized failures may occur. Technical recommendations include slope reinforcement with rock bolts, shotcrete, and drainage systems to minimize slope failure risks.

Abstract

The purpose this study is to assess geological conditions and levels of heavy metal pollution arround the artisanal gold mining area in East Tulabolo, East Suwawa District, Bone Bolango Regency, to understand its impact on the environment. This study includes geomorphological, stratighraphic, and geological structural analyses as well as measurements of heavy metal content such as arsenic (As), mercury (Hg), and lead (Pb) in river sediments. The metods used include field surveys, sampling, and laboratory analysis with ICP-MS. While pollution levels were analyzed using the Geoaccumulation Index (Igeo). The result showed that heavy metal concentrations exceeded safe limits, with the highest accumulation found in tailling sediments.. The Igeo analysis indicated a mild level of pollution due to the high concentration levels in the control area. This study emphasizes the need for sustainable waste management and ongoing contamination monitoring, including biota and groundwater sampling, to indetify risks of bioaccumulation and movement of contaminants into the wider eccosystem.

Abstract

This study aims to analyze the geological conditions and landslide potential in Tolango Village, Anggrek District, North Gorontalo Regency. The research area is predominantly composed of two main lithological units: andesite and alluvial deposits. Field observations, petrographic analysis, and structural measurements were carried out to determine the geological characteristics. In addition, geoelectrical surveys using the Electrical Resistivity Tomography (ERT) method were conducted to interpret subsurface conditions. The results show that the upper layer (1.25–3.75 m) consists of clayey soil with low resistivity values (8.10–100 Ωm), while the lower layer (up to 15.9 m) is composed of andesite bedrock with higher resistivity values (101–7,600 Ωm). A potential slip surface was identified at the contact between these two layers, which becomes critical when water infiltration increases during the rainy season. Structural features such as thrust faults and joints were also observed, indicating tectonic influence on slope instability. Overall, the integration of geological and geophysical data confirms that the area is highly susceptible to landslides, particularly on steep slopes with impermeable clay-rich layers overlying resistant bedrock.
