Abstract

Most coal mining activities in South Kalimantan apply the open pit method, which has the potential to produce acid mine drainage. As wastewater from coal mining activities, acid mine water has high acidity and metal content. Mitigation of the handling of acid mine drainage can be grouped into two processing techniques: active processing using conventional methods by neutralizing the acidity by applying quicklime. Still, in the end, this processing is considered very expensive, and passive processing is relatively cheaper but has limited processing capacity, so development with the Swampy Forest system is required. The acid mine drainage that has occurred and which has been collected in the post-mining lake is then channeled to the Swampy Forest system processing pond, which has been given organic material, and the specified types of hyperaccumulator grass and trees have been planted to change the water quality which does not meet the quality standard values to meet it. quality standard values under applicable regulations. The Swampy Forest system is proven to significantly improve water quality to meet applicable regulatory compliance requirements with a cheaper and environmentally friendly process.

Abstract

Open-pit coal mining temporarily alters natural landscapes, resulting in degraded overburden dumps and the formation of pit lakes. In Indonesia, post-mining landforms must undergo reclamation to support sustainable land use. This study evaluates the hydrological capacity of a reclaimed area functioning as the catchment for the Paringin pit lake by applying two hydrological models: the National Rural Electric Cooperative Association (NRECA) and the F.J. Mock model. Using an integrated approach that combines remote sensing, GIS-based spatial analysis, and field-based observations—including meteorological data, real-time inflow monitoring using aerial sensors, and Total Suspended Solids (TSS) measurement—both models successfully simulated monthly inflow and showed good agreement with field observations. Under a tropical climate with over 3,000 mm of annual rainfall and evaporation exceeding 1,000 mm, the catchment-to-lake area ratio of 6.4:1 was found to support sustainable inflow volumes ranging from 0.078 to 0.103 m³/s throughout the year. Although the estimated erosion rate of 3.51 t/ha/year remains within acceptable limits, average TSS levels (89.13 mg/L) exceeded the regulatory threshold of 50 mg/L for raw water supply and aquaculture use. The results affirm the effectiveness of the NRECA and F.J. Mock model in supporting post-mining water management where monitoring data are scarce. This study contributes to the growing need for hydrological connectivity assessment in post-mining landscapes and supports improved planning and sustainable management of pit lakes as integrated components of degraded post-mining land.

Abstract

Pemetaan sarana dan prasarana kelurahan Banua Anyar merupakan proses untuk memetakan dan mendokumentasikan berbagai infrastruktur dan fasilitas publik yang ada, seperti jalan, irigasi, tempat ibadah, sekolah, kantor desa/kelurahan, jembatan, listrik, air bersih, dan sanitasi.. Pendampingan pemetaan ini dilakukan untuk membantu masyarakat dalam mengumpulkan dan memverifikasi data, serta membuat peta yang akurat dan dapat digunakan untuk perencanaan pembangunan di masa depan. Beberapa manfaat dari pemetaan sarana dan prasarana tersebut antara lain dapat memudahkan identifikasi kebutuhan masyarakat, membantu pengambilan keputusan oleh pemerintah, serta meningkatkan partisipasi masyarakat dalam pembangunan kelurahan. Dengan adanya pendampingan pemetaan sarana dan prasarana yang baik, diharapkan akan tercipta kelurahan yang lebih baik dalam segi infrastruktur, kesehatan, dan ekonomi. Masyarakat kelurahan juga dapat terlibat secara aktif dalam proses pembangunan kelurahan dan merasa memiliki kelurahan mereka.

Abstract

Open-pit coal mining operations require the removal of overburden and the creation of waste dump piles. Waste dump management must consider the classification of the material, specifically whether it is Potentially Acid-Forming (PAF) or Non-Acid-Forming (NAF), based on its geochemical characteristics. This paper examined the geochemical stability of a 10-year-old coal mining overburden waste dump in Paringin, South Kalimantan, which has since been revegetated. Samples were taken from the upstream and downstream sections of the catchment area, based on the NAF homogeneous type of overburden moved to the waste dump area during the reclamation process. This was achieved by creating a soil profile to a depth of 120 cm, resulting in nine samples for each soil profile. The analysis results in the upstream and downstream sections suggested the capacity to neutralize acid. The conclusion was that the overall waste dump has stable geochemical conditions with lower acid mine drainage generation, as represented by a negative NAPP, due to the presence of adequate ANC to neutralize acidity from the Sulfur content in the upstream section and low total Sulfur in the downstream section. The geochemical stability of the waste dump, which is NAF, has a significant influence on the water quality of Paringin Pit Lake, where all surface water from the catchment area flows. These results indicated that no AMD generation occurs in the water of Paringin Pit Lake. With no potency for AMD generation, the overall post-mining landscape could have potential future utilization.
