Abstract

West Kaidundu is a village with diverse terrain conditions, covering high hilly areas, some lowlands, and coastal areas in Bulawa Sub-District, Bone Bolango Regency. The diverse morphological and geological conditions have an impact on the potential of natural resources, the distribution of limestone, and different geological structures.Research on the porosity of limestone is crucial to obtain information about its porosity value. A study analyzing the porosity of limestone in Kaidundu Barat Village has not been conducted before. Therefore, this research is significant and interesting to carry out at the study location. The results of the study reveal the geological conditions of the research area, which consists of three geomorphological units: pyroclastic ridge, karst plain, and alluvial plain units. The study area is composed of wackestone and mudstone limestone, pyroclastic breccia, and alluvial deposits. From the porosity analysis, the wackestone limestone in the study area, categorized as reservoir rock, falls into the poor category, while the mudstone limestone is classified as fair.

Abstract

This study examines the potential of limestone in Kayubulan Village, Batudaa Pantai District, Gorontalo Regency, to determine its suitability as a groundwater reservoir. The research focuses on understanding the relationship between rock density and porosity, which are key factors in water storage capacity. The methods employed include geological field mapping, specific gravity testing following SNI 1969:2008 standards, and petrographic analysis. Geological field mapping identified the distribution and characteristics of limestone facies, while specific gravity testing involved measuring dry weight (𝑊₀) and saturated weight (W_w),which were incorporated into Giancoli's (2014) density formula. Petrographic analysis was conducted to examine the inverse relationship between density and porosity in various limestone facies and to identify porosity types.Five samples representing Wackestone, Packstone, Crystalline Carbonate, and Coralline Framestone facies were analyzed for density, porosity, and water absorption. Based on Koesoemadinata's (1980) classification, porosity values were as follows: Wackestone 4.49% (negligible), Packstone 8.4% (poor), Wackestone FAK 12 10.54% (fair), Crystalline Carbonate 12.69% (good), and Coralline Framestone 23.7% (very good). Variations in micrite and sparite composition also influenced porosity; Wackestone FAK 15 showed lower porosity than FAK 12 due to its higher sparite content.Coralline Framestone emerged as the most viable reservoir candidate, as high-porosity, low-density rocks generally exhibit superior water absorption capacities. These findings highlight the significance of porosity and density in groundwater management and offer valuable insights for optimizing Gorontalo's water resources.

Abstract

Urban Heat Island is a phenomenon where surface temperatures are higher in urban areas than in rural areas. One of the cities that experienced this phenomenon was the city of Pare-pare, which was caused by the conversion of vegetation land into settlements due to rapid population growth. This study aims to determine the influence of land use on the Urban Heat Island phenomenon in Pare-pare City. The methods used include spatial analysis and descriptive analysis, secondary data collection in the study was obtained from the Indonesian Geospatial portal and Google Earth Engine and using ArcGis 10.8 software in conducting spatial analysis. The results of the analysis show that there are relationships such as Soreang, Ujung, West Bacukiki and also the north of Bacukiki District which experiences the Urban Heat Island phenomenon due to dense settlements and many road networks. Areas with land cover in the form of settlements and roads have higher surface temperatures than areas with high land cover in the form of vegetation such as the southeastern part of Bakkiki District. The impact of Urban Heat Island is that it causes a decrease in air quality and excessive energy use. The recommended mitigation is the implementation of environmentally friendly infrastructure such as greening around buildings, green roofs, and small parks. The results of this study can be used as useful information for the government in making sustainable spatial planning policies and to evaluate development to reduce the impact of Urban Heat Island.

Abstract

Flood inundation around Rawa Pening Lake has intensified in recent years, yet long-term patterns of inundation extent and persistence remain poorly quantified. This study aims to analyse the interannual and spatial dynamics of flood inundation in the Rawa Pening lake-basin system during 2019–2025 and to identify riparian zones that experience recurrent flooding. Sentinel-2 Level-2A imagery was processed within a 3 km riparian buffer to compute the Modified Normalized Difference Water Index (MNDWI), apply a histogram- and visually based threshold for water extraction, and generate annual maximum inundation and seasonal wet-season inundation-frequency metrics. The classification achieved high overall accuracy (93.1%), supporting the reliability of the derived inundation products. The multiyear results reveal strong year-to-year variability in maximum inundation and show that floodwater consistently concentrates in low-lying southern and southeastern riparian sectors, particularly within Banyubiru and Tuntang subdistricts, while western and northern sectors experience smaller and less persistent flooding. The combination of maximum inundation extent and inundation-frequency maps provides complementary insight into extreme events and recurrent flood exposure, enabling a clearer distinction between episodic and chronic flood impacts on riparian agriculture and settlements. These findings demonstrate the value of multitemporal MNDWI analysis and an ecologically defined buffer zone for monitoring lake-basin flooding and offer a spatial basis for prioritizing riparian conservation, land-use regulation, and flood-risk reduction around Rawa Pening.

Abstract

Lake Rayo in West Sulawesi, Indonesia, has been proposed as a potential meteorite impact structure, yet direct evidence supporting this origin remains limited. This study aims to provide a preliminary stratigraphic and granulometric characterization of Lake Rayo’s basin fill to clarify its genesis and support its geoheritage significance. Core sediment samples were collected from the basin floor and analyzed for grain size distribution, color (Munsell system), texture, and crack morphology using standard laboratory techniques. Seven stratigraphic intervals (BR1–BR7) were identified, showing clear vertical variations in granulometric parameters, sorting, and sediment color. Distinct fragmentation horizons, changes in color, and the occurrence of bedding cracks were interpreted as possible signatures of high-energy events, potentially associated with a meteorite impact. Comparative analysis with established impact structures, such as Lonar and Ries, revealed similar sedimentological features, supporting the impact hypothesis. These findings provide initial scientific evidence for the classification of Lake Rayo as an impact-related geoheritage site in Indonesia. The study also highlights the importance of integrating sedimentological data with future multidisciplinary research—such as geochemical and mineralogical shock analysis—to substantiate the impact origin more robustly. Overall, the results contribute valuable insights for geoheritage conservation, geoeducation, and the broader understanding of rare impact structures in Southeast Asia.

Abstract

Landslides repeatedly disrupt the national road corridor in Bunut Sub-District, Kapuas District, Sanggau Regency (West Kalimantan), indicating that slope failure is strongly controlled by subsurface conditions that cannot be reliably inferred from surface observations alone. This study delineates landslide-prone segments and interprets the subsurface slip surface using 2D electrical resistivity imaging with the Wenner–Schlumberger array. Field measurements were conducted along three 120 m survey lines using 13 electrodes with 10 m spacing, and the data were inverted (Res2Dinv) to obtain true-resistivity sections for each line. Interpretation was guided by published resistivity classifications and the local geomorphological setting. The resistivity models reveal a clear stratification of near-surface materials, with low-resistivity zones (300 Ωm) interpreted as water-saturated, clay-rich layers and higher-resistivity zones representing comparatively drier and more permeable materials. The slip surface is consistently expressed as a sharp resistivity contrast and is interpreted at resistivity values of approximately 300–2400 Ωm at depths of about 6–18 m below ground level, suggesting a mechanically weak interface that is prone to shear under intense rainfall and pore-pressure increase. These results provide spatial constraints on slip-zone geometry that can be used to support hazard zoning and to prioritize mitigation along the road section, particularly through improved drainage, surface-water control, and slope management at locations where saturated low-resistivity materials underlie permeable surficial deposits.

Abstract

Rural communities often face persistent challenges in achieving sustainable rural development due to limited technical capacity, low community participation, and weak institutional coordination in managing public infrastructure. This study evaluates the sustainability of community-based infrastructure in Ayula Selatan Village by integrating technical, social, and institutional dimensions within a participatory governance framework. A participatory qualitative approach—combining transect walks, interviews, and IMAP surveys was used to assess the performance of the community-based Drinking Water Supply System (SPAM), Domestic Wastewater Management System (SPAL), and the 3R Waste Management Facility (TPS 3R). Data were collected from 294 households to examine the system’s functionality and community engagement. Findings show that 98% of households rely on bore wells, while only one communal wastewater treatment facility serves 50 households in limited coverage. The village operates a single TPS 3R with insufficient labor and transportation, resulting in inefficient waste processing. Strong links were observed between technical reliability, participatory governance, and sanitation sustainability, where greater community involvement fostered greater ownership, accountability, and long-term infrastructure performance. Institutional partnerships further enhanced operational resilience through collaborative management. Overall, the study highlights that sustainable rural development depends on synergy between technical robustness, social empowerment, and institutional collaboration. Strengthening participatory frameworks and local capacity is essential for improving the management and long-term sustainability of community-based rural infrastructure.

Abstract

This study assesses the geosite potential of two emerging geotourism locations Rayo Lake and Sosokan Waterfall in North Musi Rawas Regency using the Modified Geosite Assessment Method (M-GAM). The research aims to address the limited empirical application of M-GAM in developing geotourism regions of Indonesia, thereby filling an important methodological and regional gap. The assessment incorporates expert and visitor perceptions to evaluate Main Values (MV) and Additional Values (AV) across geological, educational, and touristic criteria. Field surveys and questionnaire-based evaluations were conducted with 22 experts and 55 visitors. The results show that Rayo Lake attained a high MV score and a moderate AV score, placing it in quadrant Z33, indicating strong geological significance supported by adequate visitor-related attributes. In contrast, Sosokan Waterfall was positioned in quadrant Z22, reflecting moderate performance in both MV and AV categories, primarily constrained by limited infrastructure and accessibility. These findings confirm that geological attributes alone are insufficient to elevate geosite readiness without parallel development of visitor-oriented facilities. The study’s novelty lies in providing the first M-GAM-based comparative assessment for geosites in North Musi Rawas, offering actionable insights for regional planning. Strengthening infrastructure, interpretive media, and accessibility is recommended to optimize geotourism development strategies.

Abstract

The Balukang area, Sojol District (Donggala Regency, Central Sulawesi), is characterized by dioritic intrusions and active artisanal mine workings that expose mineralized rocks. This study aims to identify the presence of ore minerals, determine their host rocks, and understand the relationship between geological conditions and ore mineral formation in the area. Sampling was carried out at several observation stations identified in the field. Limited exposure restricted the sampling process, so some samples were taken from man-made mining pits that were still accessible. From all the samples collected, four representative samples were selected for petrographic analysis and six representative samples for mineralographic analysis. Petrographic thin sections and polished sections were examined using transmitted- and reflected-light microscopy to characterize mineral assemblages and textures. The analysis results showed the presence of ore minerals such as silver, gold, pyrite, chalcopyrite, sphalerite, covellite, galena, and hematite, with observed textures including intergrowth, replacement, open space filling, and mutual boundary. These textural relationships indicate hydrothermal deposition and provide a basis for interpreting mineral paragenesis in the study area. The ore minerals are associated with quartz diorite and quartz porphyry diorite as host rocks, which are controlled by intrusion lithology and geological structures. Overall, the identified mineral assemblage and host-rock association offer an initial mineralogical baseline to guide exploration targeting along veins, fractures, and stockwork zones. This study is a preliminary study, so further research is needed through detailed geological mapping, geochemical analysis, and fluid inclusion studies.
