Abstract

Soil salinization occurs when salts accumulate in the soil, damaging its structure and reducing fertility. Currently, about 20% of cultivated land is affected by salinity, and it is estimated that this figure could rise to 50% by 2050 if no preventive actions are taken. In Indonesia, saline soils are predominantly found in coastal regions, where seawater intrusion and tidal flooding are common. Pekalongan, a coastal city in Central Java with shallow groundwater, is particularly susceptible to salinization, as evidenced by increased groundwater salinity affecting a total area of 23.03 km². This study utilized Landsat 8 OLI/TIRS imagery to develop an enhanced soil salinity index for monitoring soil salinity dynamics in Pekalongan City from 2014 to 2024. Seven salinity indices were used to estimate soil salinity, and statistical analysis was conducted to examine the relationship between electrical conductivity (EC) and salinity indices derived from satellite imagery. A tailored soil salinity index, termed the modified Vegetation Soil Salinity Index (mVSSI), was developed, achieving a strong correlation with field data (R² = 0.81). The analysis showed notable changes in non-saline soil areas, which expanded from 3.32 km² in 2014 to 9.64 km² in 2024, likely due to efforts to mitigate seawater intrusion and tidal flooding. This study provides valuable insights into the dynamics of soil salinity and offers a reliable tool for monitoring and managing salinity in coastal regions, contributing to the broader goal of sustainable land management.

Abstract

This study investigated how changes in land use impact people's knowledge and perceptions, notably the transformation of wetlands into residential and industrial sectors in urban low-lying areas. This transformation's accelerating urbanization is a worldwide phenomenon fueled by infrastructural growth and urban growth. This study was carried out using a mixed-methods approach that includes surveys, interviews, and spatial analysis. This research showed a complicated link between a change in land use and how people perceive it. First, turning low-lying swamps into cities frequently changes the hydrological dynamics, raising the risk of floods and other water-related risks. As a result, people who live in transformed areas tend to develop more conscious of these environmental dangers. However, this increased awareness may not always result in proactive mitigating actions due to resource shortages and poor urban planning. Second, socio-economic position and proximity to redeveloped regions affect how locals view urban growth. While some regard land use conversion adversely owing to habitat loss and potential health hazards related to pollution and sanitation difficulties, others see it as a chance for economic expansion and improved infrastructure. Lastly, minimizing the negative effects of land use shifts depends on efficient urban planning and community involvement. People's perceptions are more likely to be positive when they participate in decision-making processes and access information and resources, increasing engagement in sustainable urban development activities.

Abstract

This study aimed to monitor and evaluate the change in the vegetation cover of the city of M'Sila based on calculating the Normalized Difference Vegetation Index (NDVI) linked to Landsat satellite image data for the years 1990-2023 and measuring the change for approximately every 10 years. The region was classified based on the index values ??into two categories: an area free of vegetation cover and an area containing vegetation cover. The results showed a difference in the area and density of vegetation cover by increasing the area of ??vegetation cover at different rates of change according to the three periods, respectively 45.98%, 6.66%, and 6.87%, which led to an increase in the area classified as vegetation cover according to the three periods 1.89 km2, 0.4 km2, 0.44 km2, with an average annual change estimated at 0.19 km2/year, 0.04 km2/year, 0.03 km2/year, where the percentage of vegetation cover in 1990 was about 8.70% of the total area of ??the city, while in 2023 it increased to record a percentage of 14.48%. This study showed the possibility of using remote sensing techniques and geographic information systems to provide valuable basic spatial information to support monitoring of vegetation cover, identifying areas exposed to environmental risks and threats, and thus developing strategies for adaptation and conservation of the ecosystems and natural resources of the study area.

Abstract

Contamination by heavy metals, especially lead (Pb) and cadmium (Cd), presents considerable environmental and public health hazards. This study examined the efficacy of a composite adsorbent composed of eggshell powder (ESP) and Palm Oil Fuel Ash (POFA) in eliminating Pb and Cd from polluted river water. BET analysis indicated that the ESP-POFA composite demonstrated enhanced surface area and pore volume post-activation, achieving a peak surface area of 38.79 m²/g at a 1:0.75 ESP:POFA ratio. The peak adsorption efficiency for Pb was 87.16%, achieved at a 1:0.25 ESP: POFA ratio after 180 minutes of agitation, whereas Cd adsorption peaked at 94.17% at a 1:0.75 ratio with the same agitation time. The adsorption capacity fluctuated according to the ESP: POFA ratio, with Pb attaining 0.00038 mg/g at the 1:0.25 ratio and Cd achieving 0.00099 mg/g at the 1:0.75 ratio. The findings demonstrate that the ESP-POFA composite is a sustainable and economical solution for water treatment and is exceptionally proficient in removing cadmium from river water. These findings endorse the composite's potential for extensive water treatment applications; nevertheless, additional modification is necessary to enhance Pb adsorption capability.

Abstract

The application of agrochemicals is still the main practice in the agroforestry system of Alas Bromo. Alfisols in Alas Bromo were characterized as acidic soil with very low soil available P. This study aimed to examine the capacity of P-solubilizing endophytic and rhizospheric bacteria from various Alas Bromo vegetation: mahogany, wresah, peanut, elephant grass, and maize in increasing soil available P and enhancing maize growth, which has the potential for reducing chemical fertilizer use. The research began with exploring and isolating bacteria using Pikovskaya agar medium, followed by in vitro tests of functional abilities and greenhouse experiments (soil incubation continued with maize planting). Rock phosphate was used as a P-inorganic source with a dose of 150 kg   ha-1. Based on the highest PSI, a total of 15 out of 52 isolated bacteria from 5 vegetations were selected to be tested in vitro and in a greenhouse experiment. Among the assessed bacteria, 3 endophytic bacterial isolates of Ad_R_5, Ah_R_4, and Zm_L_6 showed consistently high performance during successive assessments. Compared to basal treatment, the increases of soil available P, shoot fresh weight, and shoot dry weight by these 3 superior isolates ranged from 51.11-90.29%, 38.27-89.75%, and 57.04-88.73%, while the increases by NPK were 93.53, 113.67 and 107.04%, indicating the isolates had high potential for reducing chemical fertilizer use. The 3 superior isolates were identified as Pantoea dispersa, Ralstonia picketii, and Enterobacter hormaechei, respectively. Further study is needed to investigate the other potential capabilities, such as pesticide degradation and supporting plant resistance to drought stress.

Abstract

Recent data on the water quality and suitability dynamics of the Awash River, Ethiopia's most heavily used river for irrigated agriculture, with water that spatiotemporally varies in the transport pathways, is scarce. Increasing anthropogenic activities and the effects of climate change are exacerbating concerns about salinity and water quality degradation, presenting significant challenges for the sustainable management of the Awash River This study addresses these issues by using big data analytics and Geo-spatial Sci-tech to assess water quality in a robust framework, enabling precise, timely insights essential for sustainable irrigation management. The vast volume, high velocity, and complex variety of big data including pH, EC, and ion concentrations align well with these demands. Leveraging geospatial analysis, this research valorized extensive data from ten water quality monitoring stations over a period of twenty years  for tracking and visualizing water quality trends across time and space. A slightly to moderately alkaline pH, between 7.4 and 8.4, was observed in the results., while EC ranged from 0.209  to 1.161dS/m between 2004 and 2019. Ion concentrations generally followed the northward sequence of Ca²? > Na? > Mg²? > K?, HCO?? > Cl? > SO?²?, and Na? > Ca²? > Mg²? > K?. Spatial trend analysis demonstrated a positive progression of ECw, SAR, RSC, and other ionic constituents, with temporal variations indicating a progressive decline in water quality, largely due to human activities. The findings also indicated slight to moderate sodicity hazards across samples. These spatio--temporal variations underscore the importance of using updated water quality evaluations and spatiotemporal analysis to inform water management strategies.

Abstract

The study aimed to determine the optimal composition of planting material to enhance the growth of porang seedlings. The study was conducted in the laboratory of the Agronomy Department, Agriculture Faculty of Halu Oleo University, Kendari, and continued in field nursery at Wua-Wua District, Kendari City, Southeast Sulawesi. This research was carried out in two stages: (1) testing at the germination stage in the laboratory and (2) testing at the seedling stage in a field experiment. Kendari City, Southeast Sulawesi, from October to December 2021. Testing at the germination stage in the laboratory used a completely randomized design consisting of six treatments of planting media compositions, namely M0 (soil), M1 (soil + rice husk charcoal; 1;1), M2 (soil + rice husk charcoal + organic fertilizer; 1:2:1), M3 (soil + rice husk charcoal + organic fertilizer; 1:1:2), M4 (soil + rice husk charcoal + organic fertilizer; 1:2:2), M5 (soil + rice husk charcoal + organic fertilizer; 1:2:3). While the test at the nursery stage used a randomized block design, with the same treatments as the treatments at the germination stage. The findings indicated that the composition of planting media significantly affected the growth of porang seedlings. The optimal planting media composition for enhancing the growth of porang seedlings consisted of soil, rice husk charcoal, and organic fertilizer in a ratio of 1:2:3. The increase in plant growth, as indicated by stem diameter, was 133% relative to the control group.

Abstract

Post-tin mining land has low nutrient content, which makes it harder for plants to absorb macro and micronutrients. Adaptive plants such as pakchong grass and the application of nitrogen fertilizer are solutions for cultivating and increasing post-tin mining land productivity. This research was conducted to identify the most efficient doses of nitrogen fertilization for pakchong grass in post-tin mining land. This research was conducted in Kampoeng Reklamasi Air Jangkang, Bangka Regency. This research used a randomized block design consisting of 4 treatments, i.e., A0 (without N fertilizer), A1 (6.125 g N/plant), A2 (7.875 g N/plant), and A3 (9.875 g N/plant). Data obtained were subjected to analysis of variance (ANOVA) followed by the Least Significant Difference (LSD) test at a 95% significance level. The results showed that the application of different doses of nitrogen fertilizer significantly affected the dry weight of the canopy and yield per plot. The treatment of A3 (9.875 g N/plant) had the highest yield but was not significantly different from the A1 treatment (6.125 g N/plant) and A2 treatment (7.875 g N/plant). The highest fat content was in the A2 treatment (7.875 g N/plant), and the highest total N and protein content was in the A treatment (6.125 g N/plant). The best nitrogen treatment in this research was A1 (6.125 g N/plant), which had lower nitrogen treatment but had similar results with the higher dose of other nitrogen fertilizer, making it more efficient for nitrogen fertilization in post-tin mining land.

Abstract

Land use change is a significant factor in accelerating erosion rates, which is expected to increase sedimentation in the reservoir. The reduction in the water storage capacity of the dam is primarily due to sediment accumulation resulting from soil erosion. One of the approaches involves analyzing the erosion hazard level by integrating the Geographical Information System (GIS) and the Soil and Water Assessment Tool (SWAT) to accurately predict the erosion rate. The objective of this research was to assess the erosion hazard level and develop land management strategies to mitigate erosion rates in Sempor Reservoir Watershed of Central Java, Indonesia. The SWAT model employed the Modified Universal Soil Loss Equation (MUSLE) method, utilizing input data on topography, climatology, and land use provided by an authorized agency. Model calibration was conducted using the Calibration Uncertainty Program, which involved 55 iterations with 2,000 simulations per iteration, incorporating 18 sensitive parameters. Furthermore, the comparison of flow discharge between observed and simulated data is validated using statistical parameters. The results indicated that land use coverage and slope significantly influence the erosion rate. The land management strategy scenario demonstrates a reduction in potential erosion rates and sediment yield. Model calibration and validation yielded R² values of 0.87, NSE of 0.86, and PBIAS of 3.6%, indicating an excellent model fit. This suggests that the SWAT model is quite accurate in simulating the catchment area. However, the SWAT model's performance can be further enhanced by improving the adaptability of other calibration parameters.

Abstract

Landslides along riverbanks pose significant risks to infrastructure, human safety, and environmental stability. This study used a GIS-based approach to map landslide hazards and implement bio-engineering solutions for riverbank stabilization in the Cisanggarung River Basin (CRB), Indonesia. The analysis incorporated multiple parameters, including slope, soil type, land use, and riverbank characteristics, to identify potential landslide-prone areas. Data from DEMNAS, soil type maps, and land cover maps were processed using GIS tools to generate a comprehensive landslide hazard map. The results indicated that the upper and middle sections of the Cisanggarung River are particularly vulnerable to landslides, with high-risk areas identified based on slope gradients and soil sensitivity. The study further evaluated the suitability of bio-engineering techniques, such as vegetation-based stabilization, to mitigate landslide risks. The proposed solutions were focused on the highest-risk points, which were determined through scoring analysis of the identified parameters. This research provides critical insights for local authorities and environmental planners, offering a practical framework for landslide risk management and sustainable riverbank restoration in the region.
