Abstract

The soil quality of Ultisol, which is indicated by its chemical properties, arbuscular mycorrhizal fungi (AMF), and root nodules, is important for soybean growth. Cogongrass biochar enriched with N fertilizer solution using solvent from seaweed extract can change the soil quality. Using various seaweed extract solvents, this study sought to (i) test the impact of cogongrass biochar enriched with N fertilizer solution on the soil chemical quality and (ii) examine the effects of soil chemical changes on AMF, root nodules, tissue nutrient content, and soybean yield. The treatments consisted of (i) without biochar (B0), (ii) cogongrass biochar without enrichment (BN0), (iii) cogongrass biochar enriched with urea solution using solvent from extract of Kappapychus alvarezii (BNK), (iv) cogongrass biochar enriched with urea solution using solvent from extract of Sargassum sp. (BNS), and (v) cogongrass biochar enriched with urea solution using solvent extract of Ulva lactuca (BNU). In a randomized block design, each treatment was carried out three times. With or without fertilization, cogongrass biochar improves the chemical fertility of the soil. The increase in NH4+-N and nitrate-N content of the soil in enriched cogongrass biochar was greater than in unenriched. The AMF spores density and root nodules were reduced following enrichment. When biochar was added, there were more pods, pod dry weight, total seeds, and regular seeds per plant. In conclusion, the impact of increasing soil ammonium content led to decreased density of AMF spores, root infections, and root nodules. The level of available P greatly affected the components of soybean yield in Ultisol.

Abstract

Monitoring total suspended solids (TSS) is essential as suspended sediments impact the environment and human health in various ways. However, TSS data are limited in many regions because the methods currently applied through in situ measurements are time-consuming and labor-intensive. The study aimed to develop algorithms to estimate TSS using data derived from UAVs and field measurements. Remote sensing technology, such as unmanaged aerial vehicle (UAV), was applied to obtain imagery data to estimate TSS content. These results were then compared with laboratory analysis of in-situ water samples, determined by gravimetric methods following standard protocols. The results showed that the algorithm developed using three-band ratios, the blue/green + red/green + NIR (near infra red)/green, produces a high R2 (0.70), indicating that this combination is reliable for use in estimating TSS content in a river section. The high accuracy of the red band for suspended sediment prediction is attributed to its spectral signature in turbid water, which shows higher reflectance compared to clean water. The results of this study have the potential to help river managers obtain TSS data quickly at a relatively low cost.

Abstract

A crucial component of water supply in arid tropical regions is the construction of small reservoirs. Interestingly, various problems arise in the construction and management of small reservoirs, so the role of small reservoirs in providing surface water is considered less than optimal. This study aimed to identify problems that cause the function of small reservoirs to be less than optimal and to provide direction for small reservoir management in dry tropical areas. The investigation was carried out in two primary stages: site analysis to identify issues with small reservoir usability and regional analysis to identify physical characteristics regionally. Determining small reservoir points was carried out using SPOT 6/7 imagery with a resolution of 1.5 m. Land system maps and morphometry were used to analyze the physical characteristics of the small reservoir site. Field surveys and in-depth interviews were conducted to identify the benefits and limiting factors in the construction of small reservoirs. The results revealed small reservoirs are found in locations with low altitudes (0-100 masl) and undulating terrain (8-15%). According to the findings, 95.3% of small reservoirs were still water-filled. However, many problems resulted in the suboptimal utilization of small reservoirs. Specifically, the problems faced were structural damage due to 1) erosion-landslides (74.77%),  2) sedimentation (33.64%), 3) seepage (7.48%), 4) embankment collapse (6.54%), and 5) leakage (2.80%). Most of the community does not utilize the small reservoirs due to the limited infrastructure. Pipes to distribute water are only available at around 46.73%, while water tanks are only 43.93%. Directions for future management are aimed at 1) adding infrastructure, 2) sediment management, and 3) community-based management.

Abstract

This study aimed to determine the benefit of a bioagent (Trichoderma hazianum) to lessen the adverse effects of NaCl stress on date palm offshoots (Phoenix dactylifera L.) Varying concentrations of sodium chloride (NaCl) (0, 5, 10, 15, 20, and 25 dS m-1) were used to observe the effect on photosynthetic pigments, antioxidant enzymes, total proline, total phenolics, and hydrogen peroxide in date palm offshoots in the presence and absent of the bioagent T. harzainum. Results of the study showed that enhancing the NaCl concentration from 10-20 dS m-1 did not affect the mycelial growth colony of the T. harzianum in the potato dextrose agar (PDA) medium. The results indicated a significant increase in photosynthetic pigments (chlorophyll and carotenoid), levels of peroxidase and catalase enzymes, total proline, and total phenolic content in the date palm offshoots with the application of T. harzainum. A higher concentration of NaCl leads to a higher level of hydrogen peroxidation. Additionally, salt stimulated the production of antioxidant enzymes such as catalase and peroxidase. The study has indicated a significant reduction in salt stress's negative physiological and biochemical effects on date palm offshoots after applying the bioagent T. harzianum. This study showed that Trichoderma, with its ability to promote plant growth, may be employed to increase the growth of date palm offshoots developing under NaCl stress conditions.

Abstract

The use of mercury and cyanide in the gold separation process at small-scale gold mining in Pesawaran Regency can carry mercury (Hg), cyanide (CN-), lead (Pb), and arsenic (As) as other heavy metals that are also harmful to the environment. This study aimed to determine the concentration and distribution of some heavy metals (Hg, CN-, Pb, As) found in the water and sediment of the Way Ratai River. Water and sediment samples were taken at 5 points along the Way Ratai River. The heavy metal analysis method used a Mercury Analyzer, Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES), Atomic Absorption Spectrophotometry, and X-ray fluorescence. Mapping the distribution of heavy metal concentrations uses ArcGIS with the Inverse Distance Weighting (IDW) method. The results showed that the average concentration of Hg in water was 0.006 ppm, As was 0.023 ppm, and CN- was 0.003 ppm; Pb was not detected in river water. Meanwhile, in the river sediments, the average Hg was 11.83 ppm, As was 449.10 ppm, Pb was 450.88 ppm, and CN- was 0.38 ppm. It can be concluded that the concentration of heavy metals in the sediment of Way Ratai River is in the high category; the heavy metal content in river sediment is higher than that in water. For this reason, it is necessary to manage waste from gold processing activities, such as coagulation and absorption, to reduce the potential for environmental pollution.

Abstract

Landslides represent a significant hazard worldwide, leading to substantial loss of life and property. In Pakistan’s Balakot Valley, severe landslides frequently disrupt key roadways, particularly along the Balakot-Naran route, which serves as a crucial artery for tourism—the region’s primary economic activity. This study aimed to create a high-resolution landslide susceptibility map for a 457 km² area along this road, where landslides are driven by factors such as intense rainfall, weak geological formations, seismic activity, and slope destabilization due to road construction. Using Geographic Information Systems (GIS) and remote sensing, we analyzed nine critical landslide-predictive factors: slope, aspect, lithology, land cover/land use, plan curvature, profile curvature, and proximity to faults, roads, and streams. Our methodology applied the frequency ratio (FR) model to 80% of the landslide inventory data for model construction, while 20% of the inventory was reserved for validation. The resulting susceptibility map, classified into low, moderate, high, and very high-risk zones using the natural breaks method in ArcGIS, indicates that slope gradient, lithology, land cover, and stream proximity are the primary contributors to landslide occurrence in this area. Model performance metrics demonstrate high predictive accuracy, with a success rate of 0.93 and a prediction rate of 0.96. The generated susceptibility map provides a robust tool for hazard management, offering valuable insights for targeted mitigation strategies and sustainable infrastructure development in this landslide-prone region. This study advanced landslide susceptibility mapping by integrating high-impact geospatial factors with an innovative, validated FR approach, supporting safer, data-driven land use planning and disaster preparedness.

Abstract

Land use and land cover (LULC) change significantly affects hydrological processes in ungauged basins, where data limitations hinder accurate analysis and modeling. This study assesses the long-term impacts of LULC changes on the runoff coefficient (RC) and flood hydrograph in the Upper Citanduy Basin, Indonesia, using data from 2014, 2019, and 2024 to project future scenarios through 2029. The Cellular Automata-Artificial Neural Network (CA-ANN) model through the MOLUSCE plugin in QGIS was used for LULC forecasting, achieving high accuracy (Kappa>0.9). The results indicate a 16.97% increase in the composite runoff coefficient from 2014 to 2029, primarily driven by the conversion of agricultural land into built-up areas. This increase was most pronounced in the early years, stabilizing as urbanization and land degradation effects moderated. HEC-HMS simulations using Synthetic Unit Hydrograph (SUH) methods, including Nakayasu, Snyder, and Clark SUHs, revealed that peak discharges for lower return periods (RP) in the future could approach or exceed those of higher RPs in the past. For instance, the 5-year RP peak discharge in 2029 (2.137 m³ s?¹) closely resembles the 25-year RP in 2019 (2.165 m³ s?¹). Similarly, the 5-year RP in 2024 (1.794 m³ s?¹) is comparable to the 10-year RP in 2014 (1.768 m³ s?¹), while the 5-year RP in 2019 (1.727 m³ s?¹) is nearly the same as the 2-year RP in 2029 (1.734 m³ s?¹). These findings underscore the need for sustainable land-use planning and adaptive flood management to mitigate hydrological impacts in ungauged basins.

Abstract

Soil erosion occurs gradually when the impact of water or wind detaches and removes soil particles, causing the soil to deteriorate. Because of its adverse effects on biomass and economic production, soil degradation is a worldwide environmental issue. It has a wide-ranging impact on agricultural land and reservoir sedimentation, with disastrous consequences. The Upper Suvarnavathy (Honhole) river basin, Chamarajanagar district, a southern tributary of the Cauvery River of Karnataka, India, was studied to estimate average annual soil loss for a period of 63 years. Remote sensing and GIS approaches combined with the RUSLE model were employed to estimate the soil loss in the study area. To anticipate sheet and rill erosion, the Revised Universal Soil Loss Equation (RUSLE) model considers various factors, such as precipitation (rain) erosivity, soil erodibility, topographic factor, cropping management factor, and support practice factor. The study revealed that the soil erosion in the study area ranges between 0 to 6208.875 t ha?1, and the average has been estimated to be 522.30 t ha?1. This research also determined which RUSLE factor has played a significant role in soil degradation in the study area. The findings will undoubtedly aid in implementing soil management and conservation practices in critical erosion areas in this basin.

Abstract

The chemical composition of the water was determined to obtain a general picture of the geographical distribution of elements and identify the peculiarities of the elemental and chemical composition of groundwater. The analysis of heavy metal concentrations in the four wells, situated within the territory of the Karadag Reserve, revealed seasonal variations. An increase in macroelement concentrations was observed during winter, while their levels decreased during summer. The concentrations of microelements such as B (boron) and Fe (iron) decreased with increasing distance from the sea during winter and increased during summer. The analysis also identified significant exceedances of the maximum permissible concentrations (MPC) for heavy metals Li, B, Mg, Ca, Fe, Ni, and Br, as well as occasional exceedances of sodium and manganese concentrations. For all elements, the contamination factor (CF) was calculated. Based on the CF values, the pollution load index (PLI) was calculated to assess the degree of pollution by the studied elements. The results indicate the absence of pollution in the investigated area, both in summer and winter periods. To determine the degree of anthropogenic pollution by elements, the geoaccumulation index (Igeo) was calculated. Most of the studied elements do not indicate pollution either in summer or winter. However, the Igeo values for calcium indicate a moderate level of pollution during summer and a higher level during winter. The overall analysis of the results suggests that there is no serious groundwater pollution issue in the studied area by the analyzed elements.

Abstract

Peatlands play a crucial role in the global carbon cycle, water regulation, biodiversity conservation, research, education, and recreation. Peat thickness and groundwater level (GWL) are key parameters for optimizing these peatland functions; therefore, mapping peat thickness and GWL quickly, accurately, and cost-effectively is essential. This study applied a geophysical survey using a portable electromagnetic instrument to estimate peat thickness and GWL. The instrument, which is simple to operate and wirelessly connected to a mobile phone, enables rapid measurement and visualization of subsurface resistivity. A research site in Indragiri Hilir Regency, Riau Province, Indonesia, was picked up as an experiment site to test the instrument. Three transects with measurement path lengths of 100 m each and a distance of about 1.4 km each were designed for the experiment. To validate the resistivity data against subsurface stratigraphy, core sampling was conducted at three points along each transect. The results demonstrated that the electromagnetic method effectively identified the interface between peat soil and the underlying marine clay. Analysis revealed that the resistivity values for unsaturated peat, saturated peat, and saturated clay were 68-81 ohm m, 75-96 ohm m, and 82-115 ohm m, respectively. These findings suggest that GWL mapping and peat stratigraphy characterization can be accurately achieved using this method.
