Abstract

Unlicensed Gold Mining (UGM), commonly carried out using open-pit methods, leaves behind excavation voids. Over time, these voids serve as catchment areas for rainwater and surface runoff. When not properly managed and repurposed after mining activities cease, such voids may pose negative environmental impacts, including the formation of acid mine drainage. Acidic water has the potential to contaminate surrounding surface and groundwater, threatening ecosystems and public health. Moreover, the presence of heavy metals in void water raises concern due to their long-term toxicity, thus requiring comprehensive studies to assess water quality conditions in abandoned unlicensed gold mine voids. The urgency of this research lies in addressing the environmental risks posed by voids left from unlicensed gold mining, particularly concerning water quality. Therefore, this study aims to analyze the water quality of such voids in accordance with national environmental quality standards. The research employed direct surveys, water sampling from voids, and laboratory analyses with test parameters based on Government Regulation No. 22 of 2021 on Environmental Protection and Management, Annex VI, including temperature, TDS, pH, CN⁻, and Hg. The results were compared to the National Water Quality Standards stipulated in the same regulation. This study is expected to demonstrate whether the water quality in mining voids falls below the permissible limits of environmental standards, indicating safety for the environment and potential utilization by surrounding communities.Keywords: Environmental quality standards; water quality; water pollution; gold mining; void)

Abstract

Zircon sand (Zr) is widely associated with alluvial deposits, particularly in Ketapang Regency. Despite the considerable zircon resource potential, information regarding its occurrence and spatial distribution at a local scale remains limited. Identifying zircon sand occurrence is therefore essential as an initial step in evaluating and developing Zr resource potential. This study aims to determine the occurrence and analyze the spatial distribution of zircon sand in Kendawangan District, Ketapang Regency. Geologically, the study area is predominantly composed of swampy mud deposits (Qs). The geomorphology consists of two main landform units: Alluvial Plain Unit (Al) covering approximately 65% and Swamp Plain Unit (Dr) covering 35%. A total of 24 boreholes were drilled on a 150 m × 150 m grid over an area of 200 hectares. The subsurface is classified into three layers (A, B, and C), with 1 kg samples collected from each layer. Spatial distribution mapping of Zr was conducted using QGIS with the Inverse Distance Weighting interpolation method. The Zr grade distribution in Layer A is dominated by low to moderate values (6–28 mg), relatively uniform across the study area, indicating low to moderate mineralization potential. In Layer B, Zr grades are predominantly high (39–62 mg) and widely distributed, particularly in the central to southern parts, suggesting higher mineralization potential and better prospectivity for exploration. Layer C exhibits more heterogeneous distribution, with moderate to high grades (28–50 mg) covering most of the area, indicating a fairly favorable mineralization potential.

Abstract

The availability of clean water services in Sukabaru Village, Ketapang Regency, has experienced disruption due to leakage in the storage tank, low pump pressure, and blockages and leaks in the pipeline network, causing water distribution to residents to stop for several months. This Community Service Program under the Village Empowerment Scheme of Politeknik Negeri Ketapang aimed to restore the clean water supply and distribution system while supporting the sustainability of service management by the Village-Owned Enterprise (BUMDes). The program was implemented using a participatory approach involving the community service team, village government, BUMDes, and residents. The activities included field identification, technical planning, storage tank repair, installation of two 1.5 HP water pumps, pipeline network normalization, and system testing. The results showed that tank leakage was reduced, the pumping system was restored, and blocked and leaking pipelines were normalized. Following the revitalization, water flow reached households that had previously been without supply. The program directly benefited approximately 80 households. The revitalization successfully restored clean water services and supported BUMDes performance. Routine maintenance and sustainable management are recommended to maintain the functionality of the system.
