Abstract

Post-mined reclamation is an essential phase in coal mining operations, ensuring that the ex-mining area can function again according to its intended purpose in the future. This study aimed to elucidate the differences in planting years of post-mined reclamation at a coal mine in the Paringin area, South Kalimantan, Indonesia, and compared them to undisturbed areas for the years 2003 and 2023. NDVI was used for land cover analysis based on the Ministry of Energy and Mineral Resource Regulation, and the ultimate criterion for 100% success in post-mined reclamation is vegetation canopy coverage. The NDVI results showed an improvement in NDVI values for the post-mined reclamation area from 2003 to 2023, indicating an improvement in land cover due to the revegetation process. In 2023, the NDVI results of the post-mined reclamation for eight and twenty years of tree planting showed NDVI values of 0.6-0.7 (moderate vegetation). However, the results of field observations of the twenty-year post-mined reclamation tree condition indicate the non-survival of fast-growing tree species, such as Albizia chinensis. The composition of fast-growing and local tree species, with a minimum proportion of 60:40, and systematic tree distribution across the post-mined reclamation area are required to maintain canopy coverage of the post-mined reclamation area in the long term. Fast-growing tree species, as pioneers, have short to medium life periods. Therefore, the ultimate criterion for 100% success in post-mined reclamation for canopy coverage should be based on local tree species, serving as the basis for releasing the reclamation bond.

Abstract

The practice of coal mining has been demonstrated to exert a detrimental impact on the surrounding environment, particularly through the formation of acid mine drainage (AMD) ponds, which have the potential to pollute water sources. The reclamation of AMD is necessary to treat wastewater to ensure its safety for discharge into the environment and subsequent use as clean water. This study aims to treat AMD by comparing ultrafiltration (UF) and pervaporation (PV) processes utilizing silica-pectin multichannel membranes. The membranes were fabricated by coating silica-pectin sol on an inner surface of multichannel tubular support. The UF process was conducted under various pressures (1-3 bar), while the PV process was tested at various feed temperatures. Both permeate were collected and analyzed using several parameters (pH, Mn, and conductivity). The results showed that the UF process is more effective in collecting permeate flux over 136.6 L.h-1.m-2 at 3 bar pressure. Meanwhile, PV performs high permeate quality with Mn and conductivity rejection of 99.9 and 96.5%, respectively. Both UF and PV processes exhibit slightly increasing permeate pH with a range of 4.5-5.6. It concluded that multichannel silica-pectin membranes successfully reclamation AMD to enhance water quality. In addition, the UF process is more affordable for recycling AMD with high permeate flux, pretty good Mn, and conductivity rejection of over 95%.

Abstract

Air bersih merupakan kebutuhan dasar yang harus terpenuhi bagi manusia karena berperan vital dalam menjaga kesehatan, kebersihan, dan kesejahteraan. Namun akses air bersih tidak dapat dirasakan merata oleh seluruh masyarakat di Indonesia. Salah satu desa yang mengalami masalah ini adalah Desa Pembantanan, Kabupaten Banjar, Provinsi Kalimantan Selatan. Dari 996 KK tersebar dalam 12 RT di wilayah Desa Pembantanan, hampir 50% belum memiliki kesempatan mendapatkan akses air bersih. Akses oleh sumber air diperburuk ketika kualitas air baku juga menurun lebih jauh hingga menyebabkan air hampir tidak layak untuk digunakan. Oleh karena itu, kegiatan pengabdian kepada masyarakat ini bertujuan untuk membantu warga desa memperoleh solusi yang berkelanjutan terhadap penyediaan air bersih. Metode yang diterapkan adalah survei lapangan seperti pemetaan lokasi sumber air, analisis kualitas air dan diskusi dengan masyarakat tentang kebutuhan dan desain unit yang sesuai dengan mengingat sumber air di desa tersebut. Kegiatan pengabdian kepada masyarakat melalui program Kosabangsa ini ditujukan untuk memenuhi kebutuhan air bersih bagi 70 KK di RT 1 dan 2 Desa Pembantanan. Dengan menggunakan bahan baku air sungai di sekitar desa. Desain alat pengolahan air yang dipasang memiliki kapasitas produksi mencapai 2190 L/jam yang mampu memenuhi kebutuhan warga di 2 RT.

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

The sol gel process is one of the processes used in the manufacture of thin films on membranes because it can control the pore size in the resulting silica matrix. In addition, another way to build membrane size can be done by adding catalysts and precursors to be used. In this study, using a combination of tetraethyl ortho silicate (TEOS) and triethoxy vinyl silane (TEVS) precursors and citric acid as a catalyst to produce a silica matrix with mesoporous size so that it is suitable for application in the desalination process. The organo silica membrane was calcined at 350 C for 1 hour using the RTP calcination technique under vacuum, thus preventing the decomposition of carbon in the silica matrix. The membrane was dipcoated 4 times to obtain 4 layers. The FTIR (Fourier-transform Infrared Spectroscopy) test was carried out to see the functional groups on xerogel, namely silanol, siloxane and carbon. In addition, the performance of this membrane is carried out by desalination through pervaporation using 0.3% NaCl feed water with variations in feed air temperature, namely 25, 40and 60. The resulting flux of air value increased with increasing feed water temperature, namely 6.1; 11.2; and 12.1kg.m-2h-1while the resulting salt rejection was 99.72; 99.64 and 99.23%. So that the organo silica membrane is suitable when applied to the desalination process through pervaporation.

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.
