Abstract

Increasing soil salinity led to a decline in rice yield, particularly in the coastal areas of West Aceh affected by the 2004 tsunami. This study aimed to examine the characteristics of soil salinity in the coastal rice fields of West Aceh during the rainy and dry growing seasons, and to evaluate its impact on rice yield. Soil sampling was conducted using purposive sampling during two growing seasons: the dry growing season (April-September 2024) and the rainy growing season (October 2024-March 2025). Clustering analysis showed that three clusters (sodic and saline-sodic) formed during the dry season, while two clusters (sodic and non-saline non-sodic) formed during the rainy season. The Suak Pante Breuh site changed cluster membership, being sodic in the dry season and non-saline non-sodic in the rainy season. Among all soil chemical properties, soil electrical conductivity (EC) and sodium adsorption ratio (SAR) showed the strongest negative correlations with rice yield, particularly during the dry growing season (r = -0.55; r = -0.50). This study found that rice yield was more affected by salinity than by sodicity. This was illustrated in the Suak Timah 5 site, which was classified as sodic during the rainy season but showed similar rice yields to non-saline and non-sodic sites. In contrast, during the dry season, this site was classified as saline–sodic and recorded lower rice yields than other locations that were classified as sodic.

Abstract

Heavy metal contamination of agricultural soils, particularly cadmium (Cd) and lead (Pb), poses a serious threat to ecosystem integrity and food safety in rapidly urbanizing regions. This study evaluated the growth response, biomass production, metal accumulation, and translocation behavior of Ageratum conyzoides L. under varying Cd and Pb concentrations using a controlled pot experiment. Soil was amended with Cd and Pb at levels ranging from 0 to 800 mg/kg, and plant growth parameters, biomass distribution, metal uptake, bioconcentration factor (BCF), and translocation factor (TF) were systematically assessed after 60 days. The results showed that increasing Cd and Pb concentrations significantly inhibited plant growth and biomass production, particularly at higher contamination levels; however, Ageratum conyzoides L. maintained survival and metal uptake capacity throughout the experiment. Metal accumulation in plant tissues increased proportionally with soil contamination, with more than 80% of total Cd and Pb preferentially allocated to aboveground parts. Although BCF values for both metals were consistently below unity, TF values exceeded 1 across all treatments, indicating efficient root-to-shoot translocation. Specifically, 76.83 - 84.96 % of the accumulated Cd and Pb was partitioned into aboveground biomass, with translocation factor (TF) values ranging from 3.316 to 6.088 across all treatments. These findings suggest that Ageratum conyzoides L. exhibits a translocation-dominated accumulation strategy and holds considerable potential for phytoextraction of Cd- and Pb-contaminated soils, particularly under low to moderate pollution conditions.

Abstract

Agricultural land around the Medan Industrial Estate (KIM) 3 is currently facing a serious threat from cadmium (Cd) contamination, which impacts food security. This study aimed to evaluate the potential of Saccharomyces cerevisiae-fermented rice bran in suppressing the availability and accumulation of Cd in rice plants grown on Cd-contaminated soil. The treatments tested were P0 (control), P1 (100 g S. cerevisiae), P2 (125 g S. cerevisiae), and P3 (150 g S. cerevisiae), with each treatment mixed with 300 g rice bran and applied to 100 m2 of land cultivated with rice plants. The results showed that P3 was the most effective treatment for reducing Cd concentration in rice grain from 0.2 ppm to 0.010 ppm, below the Indonesian Food and Drug Supervisory Agency (BPOM) threshold. The P3 treatment also significantly improved pH and the availability of N, P, and K nutrients of the soil, leading to better plant growth and grain yield. An effective immobilization mechanism that inhibits the translocation of metals into plant tissues makes this innovation a practical, economical, and applicable solution for farmers to restore land function while ensuring food security.

Abstract

The Batanghari River is currently under serious threat due to extensive anthropogenic activities, including illegal gold mining, domestic waste discharge, and industrial effluents. This study aimed to evaluate the biogeochemical characteristics and the extent of heavy metal contamination in the Batanghari River water. Pollution indices, including the Single Factor Pollution Index (Pi), Nemerow Pollution Index (NPI), Contamination Factor (CF), Degree of Contamination (Cd), Pollution Load Index (PLI), and Potential Ecological Risk Index (PERI), were calculated to assess contamination levels and ecological risk. The results showed that the Batanghari River is heavily contaminated with heavy metals, with NPI values ranging from 4.05 to 35.8, exceeding the threshold for severe pollution (NPI>3.0). Mercury (Hg) was identified as the dominant pollutant, followed by cadmium (Cd), copper (Cu), and lead (Pb). The high Hg concentration is associated with illegal gold mining activities along the riverbanks. The computed PLI values (2.7-5.1) and Cd values (>24) confirmed deterioration in the river water quality. PERI analysis revealed very high ecological risk at several sites, with values up to 1,298, mainly attributed to Hg and Cd toxicity. Without proper treatment, the Batanghari River is no longer suitable for direct use, posing significant ecological and human health risks.

Abstract

Mine reclamation is essential to restore the natural functions of an environment. This usually starts with the planting of pioneer plants to enhance soil and trigger ecological succession. But the choice of pioneer species can have a huge impact on natural regeneration. This study investigated the impact of different planted pioneer species and their stand characteristics on the composition and number of naturally regenerated tree seedlings in a reclaimed limestone quarry. This study surveyed 14 random circular plots (radius 17.8 m) and compared the existing stand properties (Basal Area and Mean Height) and the number of naturally regenerated tree seedlings in the understory. The planted pioneer species significantly affected seedling abundance and composition, with twenty-four species identified. Enterolobium cyclocarpum (Fabaceae) was considered to be a particularly effective nurse tree and provided 'islands of fertility' for different heterospecific seedlings. Other species were found to have very large autogenic regeneration or inhibitory effects. Multiple regression indicates that BA positively (b=48.51, p=0.0009) and Mean Height negatively  (b=-17.27, p=0.00995) had an impact on seedling abundance (adjusted R²=0.627), and the total amount of seedling is compared to the light limitation by stand maturity and seedling density from 2017 to 2024. Potassium (K?) and clay content were significantly increased from 2017 to 2024. These findings highlight that a variety of pioneer species, including Fabaceae can be planted together with silvicultural interventions, including thinning to increase canopy structure, seedling recruitment, biodiversity and ecosystem recovery in post-mining sites

Abstract

Kalimantan has extensive Neogene coal reserves, making it an area with great potential for coalbed methane (CBM). After decades of preliminary investigations and studies, coalbed methane production has not yet reached the desired level. This indicates a complex interaction among geological, techno-economic, and environmental challenges. This study provides a literature review on the CBM potential in Kalimantan. A comprehensive literature study was conducted on the coalbed methane system in Kalimantan. The key parameters synthesized are the geological conditions of coal in the form of thermal maturity, gas composition, adsorption characteristics, and permeability, followed by the environmental impact and economic feasibility when applied. It appears that the greatest potential for CBM lies in the Kutai, Barito, and Tarakan basins. The reported Kalimantan coal ranks are primarily sub-bituminous to high-volatile bituminous (Ro = 0.4%-0.7%). Gas storage capacity significantly, ranging from 44 to 410 scf/ton (1.5-9.0 m³/ton). However, CBM application is hampered by poor reservoir permeability (often <5 mD) and undersaturated deposit conditions. Studies have shown that high development costs, long drying times, and unfavorable fiscal conditions have made most CBM projects uneconomical at current domestic gas prices. This review reconfirms that Kalimantan holds significant CBM resources. However, the financial viability of CBM projects depends on the ability to address significant technical barriers and requires financial incentives due to the high risks and substantial long-term investments involved.

Abstract

This study aimed to determine the effects of applying 50 t ha?¹ of compost, made from a mixture of cow dung, bromelain waste, and chopped bamboo, on soil compaction and penetration in pineapple (Ananas comosus L. Merr.) plantations in Central Lampung, Indonesia. This study used a survey method at four locations, each representing a different age of pineapple plants. Soil penetration analysis was performed using a Digital Cone Penetrometer. Soil bulk density and total pore space were determined using the volumetric method. The results indicated that soil compaction decreased with increasing pineapple plant age, corresponding to a reduction in soil bulk density. Specifically, the soil bulk density values for pineapple plants at 0, 3, 5, and 9 months after planting (MAP) were 1.42 g cm?³, 1.23 g cm?³, 1.13 7 g cm?³, and 1.02 g cm?³, respectively. Lower soil bulk density corresponded to less soil compaction, leading to lower soil penetration resistance. The lowest soil penetration value was recorded at location 9 MAP, while other locations remained below the critical soil penetration limit. A lower soil penetration value indicates reduced soil strength. There was a positive correlation between soil bulk density and specific gravity, and between soil penetration and age at 5 and 9 months. Conversely, higher soil pore space and dispersion index were associated with decreased soil penetration. In conclusion, applying 50 t ha?¹ of compost appears to be an effective solution for pineapple cultivation.

Abstract

Dieng Plateau, with Andisols, is one of the centers for potato cultivation in Indonesia. The intensive use of synthetic chemical fertilizers and pesticides to maximize potato yields has led to high cadmium levels in some potato fields, exceeding the U.S. Environmental Protection Agency's maximum threshold. Cadmium is an immobile heavy metal that can inhibit plant growth and pose health risks. Remediation of the cadmium-contaminated soil is required. This study aimed to elucidate the potential of zeolite for the remediation of cadmium-contaminated soil and the growth of potatoes. The treatments tested in this study were combinations of zeolite doses (5, 10, and 15 t/ha) and particle sizes (50, 100, and 100 mesh) applied to cadmium-contaminated soil. The variables observed were soil properties and potato vegetative growth. The results showed that applying 15 t/ha of 150-mesh zeolite significantly affected soil N, P, K, pH, and, especially, reduced soil Cd concentrations. The application of 10 t/ha of 150-mesh zeolite yielded the greatest increase (73.80%) in potato plant height, number, and leaf area. The application of 15 t/ha of 150-mesh zeolite yielded the lowest cadmium content (0.08 ppm) in the potato plant tissue.

Abstract

Shallow translational landslides on gentle slopes (~15°) in Herlang Subdistrict, Bulukumba Regency, South Sulawesi, have caused significant land degradation through soil erosion, nutrient loss, and damage to residential and agricultural areas in the weathered Walanae Formation. This study integrated 2D electrical resistivity imaging using the Wenner–Schlumberger array, Atterberg Limits testing, and Chemical Index of Alteration (CIA) analysis to elucidate landslide mechanisms and provide practical guidance for restoring degraded lands. The resistivity results indicated a saturated calcareous sandstone layer with very low resistivity (<7.53 ?m) as the main sliding mass, overlying a more competent fine tuff layer (28.9-111 ?m) at depths of 3.5-14.5 m, which serves as the slip plane. Soil samples are classified as high-plasticity clay (CH) according to the Unified Soil Classification System, with Plasticity Index values ranging from 34.55% to 39.82%. High CIA values (83.64-87.48) indicate intense chemical weathering leading to kaolinite dominance, which explains the marked reduction in shear strength upon saturation and the occurrence of translational failures even on gentle slopes. These integrated findings provide a robust scientific basis for developing low-cost restoration strategies, including subsurface drainage, terracing, and bio-engineering with deep-rooted vegetation, to enhance slope stability and restore soil function in similar tropical degraded landscapes.

Abstract

Land degradation resulting from agricultural expansion is a significant issue in the Sangarus Catchment area of Lampung, Indonesia, particularly in the upstream region. The conversion of forests into intensive agricultural land has led to declines in soil physical properties and increases in erosion rates. This study aimed to analyze the magnitude of soil erodibility (K-factor) and to evaluate its relationship with soil physical properties, to inform targeted management strategies. The research employed a Land Mapping Unit (LMU) approach, collecting 47 soil samples across the catchment based on soil type, slope, and land cover overlays. The soil samples underwent laboratory analysis for texture, structure, organic matter, and permeability. The K-factor was calculated following the Wischmeier and Smith equation. The results indicated that soil erodibility values (K) in the Sangarus Catchment area ranged from 0.01 to 0.33, with the highest erodibility observed in the upstream area, particularly within mixed dryland agriculture land use. In contrast, secondary forests exhibited the lowest soil erodibility. Statistical analysis revealed that soil permeability was the most significant factor influencing erodibility, followed by other soil properties. These findings suggest that mitigation strategies for the upstream mixed dryland agriculture zones should prioritize Nature-Based Solutions (NBS). Combining agroforestry systems with the intensive application of organic amendments is recommended as a primary strategy. These approaches are essential for improving soil permeability and maintaining organo-mineral complexes, thereby restoring hydrological functions and ensuring the sustainability of the catchment against the risks of degradation.
