Abstract

Environmental problems arising from mining include the formation of acid mine drainage (AMD), which contains high levels of heavy metals and has a low pH, requiring remediation. Block compost made from goat manure and mushroom baglog waste has the potential to remediate AMD and serve as a planting medium. The objectives of this study were to analyze the effect of block compost on AMD remediation and to assess its effect as a planting medium on the growth of Melaleuca cajuputi. This study used a completely randomized design with six block compost composition treatments: without block compost (P0), mushroom baglog waste 70% + cement 30% (P1), goat manure 70% + cement 30% (P2), goat manure 35% + mushroom baglog waste 35% + cement 30% (P3), goat manure 25% + mushroom baglog waste 45% + cement 30% (P4), goat manure 45% + mushroom baglog waste 25% + cement 30% (P5). The results showed that the treatment of block compost with various compositions (P1, P2, P3, P4, P5) was effective in increasing the pH of AMD from 3 to 5.1-6.4 and reducing the concentration of Cd, Cu, Pb, and Zn metals by 45.74-82.70% within 5 days. The application of block compost with various compositions also had a significant effect on the height growth of Melaleuca cajuputi. The P3 treatment significantly increased the height of the seedlings to 34.00 cm within 8 weeks.

Abstract

Land degradation is one of the biggest challenges to agricultural sustainability in tropical regions, mainly due to the pressures of land intensification, climate change, and unsustainable soil management practices. Soil deterioration can occur in physical, chemical, and biological aspects, thereby reducing the soil's capacity to support agricultural productivity. This study aimed to evaluate the status of soil deterioration through a multi-parameter approach in the dryland ecosystem of North Halmahera, Indonesia. The parameters analyzed include solum thickness, surface stoniness, fraction composition, bulk density, porosity, water permeability, pH, electrical conductivity (EC), redox potential, and microbial population. The results showed that all points experienced degradation, with four points (T1, T2, T4, T5) classified as moderately deteriorated and the other four points (T3, T6, T7, T8) classified as severely deteriorated. The main factor of deterioration was very high salinity (29-50 mS/cm), far exceeding the critical threshold, which caused osmotic stress and ion toxicity to plants, low redox (100 mV), high bulk density (1.83-1.99 g/cm³), extreme porosity (>70%), and low microbial population (<10² CFU/g) at several points. However, the soil pH is relatively neutral (6.8-7.0), so it is not a limiting factor. The results of this study are used as reference material for sustainable land management to achieve the sustainable development goals.

Abstract

Artisanal gold mining activities in Indonesia often cause mercury (Hg) pollution, which is toxic and bioaccumulative. Phytoremediation using Pteris vittata L. as a hyperaccumulator and rhizobacteria Pseudomonas aeruginosa RTKP1 is an alternative to overcome this problem. This study aimed to analyze the effect of combined treatment of Pseudomonas aeruginosa RTKP1 induction and compost on the ability of Pteris vittata L. to accumulate Hg in gold mine tailings. The treatment consisted of bacterial induction without compost, and with compost at a tailings:compost ratios of 1:1 and 2:1. This study used descriptive and quantitative analyses. The results showed that Pseudomonas aeruginosa RTKP1 induction without compost resulted in the highest reduction in Hg levels in the tailings, from 10.7 mg/kg to 0.00467 mg/kg with a medium-high BCF value and TF <1, indicating a phytostabilization mechanism. However, the addition of compost reduced the effectiveness of bioaccumulation. Hence, treatment of Pseudomonas aeruginosa RTKP1 without compost was most effective in increasing the ability of Pteris vittata L. to reduce mercury content.

Abstract

This research investigated the effectiveness of bioremediation of Lapindo mud-contaminated soil using an eco-enzyme for total petroleum hydrocarbons (TPH) removal. The soil samples were collected from Glagaharum and Gedang Villages, Sidoarjo, East Java, Indonesia, which have been contaminated by the Lapindo mud containing TPH. The bioremediation experiment was carried out ex situ in a container filled with contaminated soil samples, which were watered with eco-enzymes daily. Bioremediation time was optimized at 0, 7, 4, 21, and 28 days while the eco-enzymes concentration was varied at 0, 5, 10, and 15% (v/v). The concentration of TPH in the soil samples was analyzed using the gravimetric method at 0, 7, 4, 21, and 28 days. The results showed that TPH concentration was gradually decreased during remediation. The remediation removal percentage reached an optimum after 21 days. The TPH was optimally removed using the eco-enzyme at 15% (v/v), achieving 95.39%. The bioremediation of contaminated soil using eco-enzymes also increased the contents of total C and total N by 50.97% and 39.43%, respectively. However, this treatment reduces total P by 50.89%. Furthermore, the pH and temperature values for the three samples before and after the bioremediation process remained fairly stable, within the pH range of 6-7 and the temperature range of 25.7-26.2 °C.

Abstract

Landslides are among the most common geological hazards in Indonesia, particularly in areas with steep topography and complex geology. This study was conducted in the Banjarsari Area, Ciamis Regency, West Java Province, Indonesia, to assess landslide susceptibility using morphographic and morphometric approaches based on Digital Elevation Model (DEM) data and field observations. The results showed that more than 35% of the study area has slope gradients exceeding 15%, indicating it is landslide-prone terrain. Hilly morphographic conditions and morphometric characteristics influenced by geological structural control contribute to the occurrence of translational, rotational, and rockfall-type landslides identified during field surveys. Landslide susceptibility was further quantified using the Landslide Susceptibility Index (LSI), which integrates slope gradient, landform, drainage pattern, slope aspect, and field indicators. The spatial distribution of LSI values ranges from low to very high susceptibility and shows strong agreement with observed landslide locations. Areas with higher LSI values indicate zones of greater slope instability and provide an objective basis for prioritizing landslide mitigation efforts and for supporting risk-informed land-use planning in the study area.

Abstract

The central sector of the Kosovo Plain, an area undergoing intense industrial and urban expansion, was selected to analyse the interrelationship between agricultural land use, coal mining operations, and land cover transformations. A geospatial analytical framework, using A GIS-based analytical framework was employed to assess land cover dynamics over the past two decades. This study critically examined the spatial and temporal patterns of land use change within one of the most densely populated and economically significant regions in both Kosovo and the broader Balkan area with the aim of quantifying the rate, magnitude, and direction of these changes to address the current gap in regional-scale assessments. Extensive lignite extraction central to Kosovo’s energy sector has driven the conversion of arable land into mining zones. However, the prevalence of open-pit lignite extraction has led to substantial environmental changes, particularly the conversion of arable land into mining zones. The study evaluated land cover transformations associated with environmental impacts between 2000 and 2018. Results indicated a 10% decline in agricultural land and a 59% increase in artificial surfaces between 2000 and 2018, reflecting intense urban and industrial expansion across the Kosovo Plain. These trends highlight accelerating anthropogenic pressures and underline the urgent need for integrated spatial planning and sustainable land management policies in Kosovo’s rapidly transforming lowlands.

Abstract

Phosphorus (P) deficiency in intensively cultivated Inceptisols is a persistent problem, not only because of low P reserves but also because of ongoing soil degradation, which reduces fertilizer use efficiency and is characteristic of degraded soils. This study aimed to develop a “new” humic acid from water hyacinth biomass (WHL) through accelerated aerobic decomposition using lignocellulolytic microorganisms and to evaluate its effectiveness in improving soil P dynamics and chili growth responses. The experiment was conducted on P-deficient Inceptisols of the Jatinangor series characterized by low P availability and high metal content. Water hyacinth collected from local reservoirs and rivers was aerobically decomposed with selected microbial starters to enhance humification. WHL was applied in combination with inorganic P fertilizer (SP-36), and its effects on soil P availability, phosphorus dynamics, and chili pepper growth and yield were evaluated using path analysis. The results showed that WHL significantly improved P dynamics mainly through an indirect mechanism involving increased P availability and reduced P fixation, thereby improving chili growth and yield. Application of WHL at a rate of 30 kg ha?¹ combined with SP-36 at a rate of 250 kg ha?¹ produced responses comparable to those obtained with commercial humic acid. These findings indicate that WHL has strong potential as a renewable and cost-effective alternative source of humic acid to improve phosphorus efficiency, restore soil chemical function, and reduce dependence on inorganic P fertilizers in degraded Inceptisols under intensive cultivation.
