Abstract

The use of geosynthetic containers (geotubes) is a promising technology for the elimination of environmental pollution from industrial and subsurface use waste, based on the storage and dewatering of liquefied waste inside geosynthetic shells. The problem of environmental pollution from the mining industry is relevant since this industry is one of the leading areas of the world economy. Geotubes have found their application to solve some of the challenges facing the industry. However, in most cases, geotubes are not integrated into technological processes and do not use all the possibilities of their application. The data, effective methods, and technologies, examples of applications in various areas of the mining industry. he main advantages and disadvantages of technologies are presented. Examples of the use of geotubes in mining, including the development of placer deposits, the construction of structures, the operation of sludge storages, dumps, are considered.

Abstract

This study examined the potential of repurposing agricultural waste as biofilm carriers in Moving Bed Biofilm Reactors (MBBRs) for wastewater treatment. The goal of this experimental research was to reduce the wastewater treatment costs. This research focused on two agricultural by-products: banana stems and corn stalks. These materials were tested as biofilm carriers in a laboratory-scale MBBR setup. Banana stems and corn stalks were prepared to facilitate biofilm formation before being incorporated into the reactor. Results revealed that banana stems achieved reductions of 27% in COD and 32% in BOD, with TSS dropping by 69% during treatment at a filling ratio of 40%. Despite these reductions, the low density of banana stems led to less effective pollutant removal. In contrast, corn stalks demonstrated superior performance, achieving 69% and 83.6% reductions in COD and BOD, respectively, and a 66.7% reduction in TSS at a 40% filling ratio. The higher surface area and better integration of corn stalks with wastewater contributed to more efficient biofilm formation and pollutant degradation than banana stems.

Abstract

Economic growth is the key to community welfare, especially in rural areas. Using land wisely is a simple way to improve the community's economic quality. At its core, the issue is whether the available land can be used most effectively since lousy management can lead to land degradation. This study aimed to identify the status of land carrying capacity and various strategies that can be carried out to optimize land in South Sorong, Indonesia. A spatial approach was used to analyze existing land conditions. Furthermore, the carrying capacity status was identified by considering land availability and potential community needs. Pressure State Responsibility (PSR) analysis was used to identify solutions that can be employed to maximize land resources. Research findings showed that existing land in South Sorong is dominated by forests (40.04%), swamps (36.47%), and mangroves (13.02%). The land carrying capacity status in South Sorong has a surplus value, meaning that existing land is more than sufficient to meet the population's needs, which depends on its productivity. Land development and optimization can be carried out but must involve multiple stakeholders and be carried out in a planned and careful manner so that environmental sustainability is maintained. Land optimization strategies that can be done are intensifying agriculture, adding infrastructure, and introducing mechanical technology in land management. Finally, the finding can be used as a basis for policymakers, especially in rural areas where the land carrying capacity status is still surplus.

Abstract

Urban areas in Bali are facing increased risks due to the effects of climate change and intensive land degradation, resulting from rapid land conversion and non-environmentally friendly development processes. Green infrastructure provides an integrated and environmentally friendly solution for rehabilitating degraded lands and enhancing the resilience of cities. This research examines the application of green infrastructure in four urban locations in Bali—Denpasar, Badung, Gianyar, and Tabanan—emphasizing the rehabilitation of ecosystems and the role of universities as a central hub. Based on a qualitative case study approach corroborated by quantitative environmental data, the study evaluated the efficacy of green infrastructure projects in improving water and soil quality, minimizing erosion, and improving infiltration rates. Results indicated substantial ecological benefits with implementation, highlighting the role of institutions of higher learning in research, public education, and technological innovation. Although the findings are encouraging, numerous challenges remain, including inadequate financial support, sporadic project allocation, and limited public awareness. This study provided policy and practical recommendations for integrating green infrastructure into spatial planning and enhancing university-government collaboration to ensure sustainable urban development and land reclamation in climate-vulnerable regions.

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 Wapulaka Formation in Central Buton, Indonesia, is a tectonically complex carbonate system characterized by heterogeneous lithologies, including limestones, dolostones, and marls. This study integrates Electrical Resistivity Tomography (ERT) and X-Ray Fluorescence (XRF) to map the subsurface distribution and geochemical characteristics of limestone in the formation. Electrical Resistivity Tomography (ERT) surveys were conducted along four profiles, covering a total length of 495 meters, with an electrode spacing of 5 meters to identify resistivity variations linked to lithological changes, fractures, and karst formations. The collected data were processed and inverted with Res2DInv software, applying topographic corrections to produce high-resolution 2D resistivity models. The limestone samples were examined with an Epsilon 4 XRF spectrometer to ascertain the elemental concentrations, particularly the CaO and MgO levels. Borehole data were used to validate ERT findings and provide a lithological perspective. The amalgamation of the ERT and XRF datasets demonstrate a robust correlation between resistivity and chemical composition. High-resistivity zones (>5000 ?m) are associated with significant, high-purity limestone characterized by elevated CaO and reduced MgO levels, while low-resistivity regions (<1000 ?m) signify eroded, porous, or clay-rich portions with increased MgO and diminished CaO content. The Mg/Ca ratio, obtained from XRF analysis, acts as an indicator of dolomitization, with higher ratios linked to decreased resistivity values. This technology facilitated the creation of a predictive model for limestone quality utilizing resistivity, enhancing resource assessments and selective mining efficacy. This study illustrates the efficacy of integrating geophysical and geochemical methods to delineate intricate carbonate systems, providing insights into subsurface heterogeneity, diagenetic processes, and resource availability.

Abstract

Heavy metals in high concentrations from industrial areas are deposited in the soil and, as a result of ecosystem interrelationships, enter and are harmful to living beings. To determine if there is translocation of metals from the soil to herbivorous animals, the team of the Laboratory of Learning, Technology and Democratization in Soils and Communities (LAPTES) conducted a first exploratory study and then a complementary study of the translocation of heavy metals such as Copper (Cu), Arsenic (As), Cadmium (Cd) and Lead (Pb) in localities near the Ventanas Industrial Complex (CIV). Fecal samples were collected from different points of the La Greda School, using standard methods for the determination of heavy metals in certified laboratories. The results were analyzed using correlation coefficients, Spearman correlation matrix, and descriptive statistics. It was shown that there was a correlation between the presence of metals in the soil and the feces of herbivorous animals. It is concluded that there would be a risk in the hunting and consumption of local lagomorphs on contaminated soils, affecting food security, making it necessary to strengthen environmental education through soil remediation in contaminated territories, considering the active participation of the communities.

Abstract

This study developed the indigenous CR3.M3 bacterial consortium to enhance oil degradation in saline-contaminated soils. Seven hydrocarbon-degrading strains-closely related to Pseudomonas, Bacillus, and Niveispirillum species (92-99% 16S rRNA sequence similarity)-were isolated from polluted coastal soils using mineral salt media supplemented with crude oil and diesel. While phylogenetic analysis suggests close relationships to known oil-degrading species, formal taxonomic classification requires further genomic validation. The consortium degraded 70% of hydrocarbons within 13 days under saline conditions (?3% NaCl). Field trials in non-sterilized soils (3,542 mg/kg TPH) achieved 65.42% oil removal alongside microbial density increases from 6.26 to 8.11 Log??(CFU/g), confirming ecological compatibility. Its performance in both sterilized and native soils highlights adaptability for coastal bioremediation. Future research should optimize strain ratios, resolve taxonomic identities through whole-genome sequencing, and assess long-term ecological impacts to advance this sustainable remediation strategy.

Abstract

Palembang City frequently experienced flooding during the rainy season, necessitating effective urban water management strategies such as the development of retention ponds. This study employed several analytical methods, including erosion level assessment using the Universal Soil Loss Equation (USLE), sediment yield estimation through bedload traps and suspended sediment samplers, dead storage volume analysis by comparing storage capacities before and after sedimentation, sediment thickness rate calculation based on total erosion per unit area, and retention pond lifespan prediction using dead storage capacity, sediment discharge, and sediment specific weight. The results indicated extremely severe erosion rates ranging from 3,241 to 4,593 t/ha/year (>480 t/ha/year) and very high sediment yields between 4,368 and 7,018.5 t/year (>500 t/year). Sediment accumulation reduced storage efficiency, with dead storage volume reaching 44–61.11%. Siti Khadijah, RC reservoir, Talang Aman I, and IBA retention ponds were classified as having very large dead storage volumes, while Talang Aman II retention pond was in a large category. Sediment thickness rates ranged from 227.2 to 397.9 mm/year (>50 mm/year), indicating a very high sedimentation rate. Consequently, the estimated operational lifespan of the ponds was very short, between 1.86 and 6.36 years (<10 years). In conclusion, the retention pond areas in Palembang exhibited critical erosion and sedimentation issues, resulting in high sediment accumulation, reduced storage capacity, and significantly shortened pond lifespans. These findings highlight the urgent need for sustainable sediment management and maintenance strategies to enhance the effectiveness and longevity of urban retention ponds.

Abstract

The study aimed to determine the level of pollution sensitivity associated with fertilization activities in agricultural land in two karst spring catchment areas (Beton and Guntur). The aquifer characteristics of these two springs differ; the Beton Spring has a more developed allogenic channel development, whereas the Guntur Spring has a less developed autogenic system. In this study, the COCKPIT-PLUS and Master Recession Curve (MRC) techniques are combined to define land use zoning and the degree of aquifer sensitivity to pollution. Field sampling and stakeholder interviews were also conducted to assess land management practices and pollutant concentrations in the springs. The results show that due to the influence of more intensive and varied land use, Beton Spring has a higher sensitivity to pollution, as evidenced by higher concentrations of nitrate, phosphate, and Escherichia coli. In contrast, lower pollution levels in Guntur Spring occur due to the narrower recharge zone area supported by a more consistent planting pattern. Various strategies, including vegetative restoration, drainage planning, land use regulation, and communicative education, were formulated using the DPSIR framework. Strategies are critical in areas with high sensitivity, such as the Beton and Jomblangan recharge zones, which also highlight the necessity of land use restrictions based on upstream-downstream interactions. This study emphasized the importance of adapting the protection plan for karst aquifer recharge zones in response to land use intensity and degradation. It proposes an evidence-based integrated management model that focuses on decreasing the effects of land degradation in tropical karst aquifer systems.
