Abstract

The degraded Latosol soil is characterized by its acidity and low organic matter content, which limits rice productivity. Improving the chemical properties of the soil is crucial for supporting the sustainability of paddy fields. This study aimed to enhance these properties using silica-enriched biochar through gamma irradiation as a biofertilizer carrier. Rice husk biochar was selected for its resistance to decomposition and was enriched with SiO? to fulfill the nutritional needs of rice plants. The treatments tested were combinations of biochar-silica formulas (F0 = no formula, F1 = biochar-silica with rice husk ash, and F2 = biochar-silica with zeolite) and NPK fertilizer doses (R0 = no fertilizer, R1 = 50% recommended dose, R2 = 100% recommended dose). The results showed that the F1 formula combined with the full NPK dose (R2) significantly improved soil structure, increased organic carbon content, and enhanced nutrient uptake efficiency, which in turn, promoted higher rice productivity. The use of silica-enriched biochar as a carrier for biofertilizers has proven effective in supporting the sustainability of paddy soils. The F1 formula with a full dose of NPK can be recommended to enhance rice productivity while maintaining soil fertility.

Abstract

Badung River, a primary irrigation source for the subak system in South Denpasar, has been reported to contain excessive levels of heavy metals, exceeding the standard quality for irrigation water. Corn cultivated on subak systems irrigated by this irrigation source had heavy metal residues in its roots and kernels. Long-term consumption of corn containing heavy metals such as Pb, Cd, Cu, Cr, and Hg will cause toxicity to plant tissues and the human body. This study examined the content of heavy metals in soil and corn plants in subak systems in South Denpasar, which are irrigated with water from the Badung River. Remediation of the soils contaminated by heavy metals was conducted using rice straw and husk biochar (Br), coconut coir and shell biochar (Bc), vegetable and fruit waste biochar (Bw), and lignohumic biochar (Bl). The study also evaluated the effect of applying biochar on growth and yield of corn grown on soils contaminated by heavy metals. The results of this study showed that the heavy metal contents in the soil and irrigation exceeded the threshold for soil and water quality standards. The application of Bl yielded the highest biomass fresh weight and seed weight at 14% moisture content compared to other treatments. The Bl treatment also resulted in the best performance in binding and translocating heavy metals based on the bioaccumulation and translocation values ??of the biochar types. Hence, it can be concluded that the most suitable biochar for the remediation of heavy metal-contaminated paddy soils in subak systems is lignohumic biochar.

Abstract

This study investigated the lateral distribution of geochemical parameters in peatlands within the Punggur Besar River–Kapuas River Peat Hydrology Unit (KHG) in Kubu Raya District, West Kalimantan Province, Indonesia. Peatland degradation in this area is primarily caused by land clearing, uncontrolled drainage, and forest fires, which adversely impact the soil's physical and chemical properties. Key geochemical parameters analyzed include nitrogen (N), phosphorus (P), potassium (K), pH, organic carbon, and cation exchange capacity (CEC). Spatial distribution was mapped using GIS technology. The results showed significant variation in nutrient content and soil pH across the study area. Nitrogen content varied between 0.1% and 1.6%, indicating areas of high and low vegetation productivity. Low phosphorus levels in most regions suggest nutrient deficiencies, while potassium concentrations exhibit variability, indicating a potential need for fertilization. Predominantly acidic soil pH (2.8-6.3) challenges vegetation growth and increases fire risk. These discoveries contribute to a fundamental understanding of the geochemical dynamics of peatlands, indispensable for leading sustainable management and restoration efforts. By recognizing areas of high fertility and those requiring restoration interventions, this research assists effective land-use planning and climate mitigation strategies in degraded peatland ecosystems.

Abstract

Potentially toxic elements (PTEs) have become a significant global concern due to their detrimental effects on both ecological and public health. Monitoring these elements is crucial in areas suspected of having high concentrations. In Camarines Norte, small-scale gold mining (SSGM) activities have been linked to elevated mercury levels in soils and sediments, as it is commonly used in the gold extraction process. In this study, six (6) SSGM wastes from Camarines Norte were collected, analyzed, characterized, and assessed for pollution by eight (8) PTEs: arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), nickel (Ni), lead (Pb), zinc (Zn), and mercury (Hg). Analytical techniques such as energy dispersive x-ray fluorescence (EDXRF), x-ray diffraction (XRD), inductively coupled plasma – mass spectrometry (ICP-MS), and direct mercury analyzer (DMA) were utilized. Analysis shows quartz (SiO?) as the primary mineral among all samples, with some also containing albite, biotite, kaolinite, microcline, and sphalerite. Pollution was assessed using enrichment factor (EF) and index of geoaccumulation (Igeo), which showed that the SSGM waste samples were extremely enriched and contaminated with As, Cd, Cu, Hg, Pb, and Zn. Gold concentrations were also measured, revealing high levels of enrichment in the samples. Furthermore, one of the SSGM waste samples underwent Hg leaching using environmentally friendly solvents, including deep eutectic solvents (DES). The reduced mercury concentrations after leaching demonstrate the potential application of DES for mercury remediation.

Abstract

Rapid population growth in Bandar Lampung, especially in coastal areas, has impacted the environment. Pasaran Island is a small inhabited island that originally only had an area of 2 ha but has now grown to 12.02 ha due to sedimentation and reclamation carried out by the island's residents. Pasaran Island faces great challenges, especially related to carrying capacity and capacity to maintain environmental sustainability and the quality of life of its residents. This study aimed to analyze the carrying capacity and capacity of Pasaran Island. A spatial analysis approach was used to evaluate land requirements and the limits of the island's ability to support its population optimally. Spatial calculations used were according to the Regulation of the Minister of Public Works No.20/PRT/M/2007 on techniques for analyzing physical, environmental, economic, and socio-cultural aspects in preparing spatial plans. The results showed that the carrying capacity on the Pasaran Island is 0.601, which means that the carrying capacity of the settlement is low and unable to accommodate the population in the area. Based on the analysis of the carrying capacity of people, when viewed specifically on Pasaran Island, it can only accommodate 827 people, even though there are currently 1,500 residents. Thus, the results show that there is an overpopulation of 673 people.

Abstract

Preserving isolated plant populations and defining their geographic range, especially for rare and threatened species, is vital in conservation ecology. The current study examined the ecological status and potential conservation trajectories of Juniperus oxycedrus subsp. macrocarpa (Sm.) Neilr in the only Libyan area with significant populations of this tree. The habitat was identified, and its climatic, edaphic, and vegetation characteristics were analyzed. The species' landscape distribution was studied, with regeneration and mortality percentage estimated, along with influencing factors. The results revealed that the soil in the area is predominantly sandy in texture and infertile. The accompanying vegetation cover is comprised of 112 species and dominated by dwarf plant species. Previous records of this tree species east of Derna City are no longer extant. The study documented 4135 scattered trees covering an area estimated at around 260 hectares, with another 24 individuals located along the road to Al-Qubah city. The average height of the trees was 2.33 m, while the average canopy area and volume per individual were 38.18 m2 and 174.30 m3, respectively. The percentage of regeneration was estimated at 16.42%, while the mortality was 3.07%. Despite their apparent resilience to poor soil properties, arid climate, and proximity to the sea, this tree is primarily threatened by unsustainable human activities, resulting in habitat alteration and landscape modification. Therefore, urgent and efficient management measures are required to preserve this taxon at the national level. This should involve designating the study area as a protected zone to ensure long-term ecological conservation and sustainable management

Abstract

Land cover changes resulting from mining activities in Central Bangka District have often led to environmental degradation, significant challenges for local communities, and disruptions to spatial utilization. This study aims to identify land cover change patterns within the tin mining business license (IUP) area from 2014 to 2022 and evaluate their impacts on ecosystems and land use. The study employed the Maximum Likelihood Classification (MLC) method for satellite image analysis to detect land cover changes. The results indicated that mining land expanded by 2,117.29 ha between 2018 and 2022, primarily due to the conversion of secondary and natural vegetation. Meanwhile, secondary vegetation declined significantly, with 4,187.46 ha reduction from 2014 to 2022, highlighting the extensive exploitation of land for mining activities. Additionally, an increase in water bodies was observed due to the formation of water-filled mine voids, locally known as "kolong". The classification accuracy assessment demonstrated high reliability, with Kappa coefficients of 93.7% in 2014, 92.73% in 2018, and 94.5% in 2022, confirming the effectiveness of the MLC method in detecting land cover changes. The findings of this study provide critical insights for post-mining land management, emphasizing the need for enhanced reclamation and revegetation strategies. A more comprehensive understanding of land change dynamics is expected to support sustainable spatial planning and inform environmental impact mitigation policies in Central Bangka District.

Abstract

The article examines the impact of inorganic carbon content on the soil pH environment, humus content, and the population of humus-decomposing microorganisms in newly formed soils on the dried bottom of the Aral Sea. The studies were conducted in 3 regions. The highest inorganic carbon content was 24.41% in the soils of Region III, while the lowest content was 9.18% in the soils of Region I. The inorganic carbon content in the soils affected the pH environment. In Region III, where inorganic carbon was more accumulated, the pH environment reached up to 8.6, indicating a higher alkalinity. In contrast, the soils of Region I, with lower inorganic carbon, had a pH of 7.1. The humus content also varied depending on the inorganic carbon content. In Region III, the humus content was 0.12%, while in Region I, it was 0.80%. The inorganic carbon content also influenced the number of humus-decomposing microorganisms. The results indicated that as the inorganic carbon content increased, the number of humus-decomposing microorganisms decreased. The results of the statistical analysis (LDA, PCA, Correlation, Regression, General statistics) are positive. Specifically, the F statistic is 657.5 (p<0.001), indicating that the analysis results are highly reliable and statistically significant. The study shows that inorganic carbon content in Aral Sea soils affects pH, humus levels, and humus-decomposing microorganisms, with higher carbon leading to higher pH and fewer microorganisms. Statistical analysis confirms reliability.

Abstract

Groundwater pollution from industrial, agricultural, and municipal sources presents a critical environmental challenge, necessitating adopting sustainable remediation strategies. As a result of this crucial issue, groundwater remediation strategies have gained traction, with a particular focus on sustainable techniques. Among these, Permeable Reactive Barriers (PRBs) are considered a promising, low-cost, and sustainable groundwater remediation approach. This review examines the main concept, configurations, design procedures, and applications of PRBs, emphasizing their role in intercepting and degrading pollutants through various removal mechanisms such as adsorption, ion exchange, and microbial activity based on the used reactive materials. The selection of reactive materials is explored concerning their effectiveness in contaminant removal, while different PRB configurations are analyzed for their environmental benefits, hydraulic performance, and cost efficiency. This study also analyzes the challenges associated with PRBs, including site heterogeneity, material selection, and maintenance requirements. By synthesizing existing research and real-world applications, this study provides a detailed evaluation of PRBs as a promising technology for sustainable groundwater remediation.
