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.

Abstract

Organic farming has been advocated as a more environmentally sound and ecologically balanced alternative to the dominant agricultural model. This study compared the decomposition of plant biomass in organically and non-organically managed soil properties. The treatments consisted of   non-organic land (A) and organic land (B). Non-organic land used chemical fertilizers as the main fertilizer, and organic fertilizers were not always given. In organic land, all fertilizers given were organic fertilizers, and organic pesticides have been carried out over the last five years. The area of ??each land studied was approximately 1,000 m2 divided into five points diagonally. Observations were made on soil pH, organic C, total N, and P Bray, as well as the amount and weight of soil macrofauna. The decomposition rate of the dried Edamame soybean biomass in the soil was estimated using the litterbag method. A litterbag measuring 30 x 20 cm with a pore size of 2-3 mm was used for this study. Seventy grams of plant biomass were put into the litterbag and buried in the soil to a depth of 10-20 cm. Analysis of C and N contents in plant biomass was carried out before and after incubation in the soil. The results showed that soil chemical properties are better, and soil macrofauna is more abundant in organic than non-organic land. Soil fertility in organic land was characterized by a larger decomposition rate constant (k) and a faster decrease in C/N ratios. The decomposition rate constant (k) in organic soil was 0.171, and that in non-organic soil was 0.105.

Abstract

The Karimunjawa National Park area has various coastal resources and ecosystems, such as mangrove forests, seagrass, and coral reefs, which provide a habitat for several vital organisms. The presence of natural and human factors in coastal areas causes environmental degradation. Changes in environmental conditions, increasing population, and land requirements in Karimunjawa National Park can have negative impacts if not appropriately managed. Therefore, coastal management strategies are needed to maintain sustainability and prevent the extinction of coastal resources. The research locations are Karimunjawa Island and Kemujan Island. This research aimed to develop a coastal management strategy based on changes in the shoreline of Karimunjawa Island and Kemujan Island. The SWOT (Strengths, Weaknesses, Opportunities, Threats) analysis model was used to identify coastal management strategies through the most effective priority scale. The research results showed that in 2008-2023, the average erosion on Karimunjawa Island was -11.41 m or -0.75 m/year, and accretion was 13.30 m or 0.87 m/year, while the average erosion on the island rainfall was -13.74 m or -0.90 m/year and accretion is 13.30 m or 1.07 m/year. Management strategies that can be implemented are (1) forming a board or committee; (2) conducting outreach and education activities; (3) identifying critical areas; (4) developing protection and utilization programs; (5) conducting research; (6) monitoring; (7) formulating policies.

Abstract

Degraded alluvial soil that is commonly used for growing ginger (Zingiber officinale) has many issues, such as deficiency in nutrients. To increase the yield of ginger, proper fertilizers along with soil improvement techniques must be employed. In this case, the study analyzed the combined effects of rice husk biochar and Mahkota NPK fertilizer on the yield and growth of ginger in alluvial soil. The study was performed using a completely randomized design arranged with two treatment factors. The first factor was the application of rice husk biochar consisting of three different levels: s1 (5 t/ha), s2 (10 t/ha), and s3 (15 t/ha). The second factor was the application of Mahkota NPK fertilizer consisting of three levels: m1 (50 kg/ha), m2 (150 kg/ha), and m3 (250 kg/ha). The results of this study showed that the treatment combination of rice husk biochar and Mahkota NPK fertilizer was highly significant in improving bulk density, total porosity, pH, organic C, total nitrogen, available phosphorus, and potassium of the Alluvial soil. The interaction also greatly affected plant growth in terms of height, tiller formation, and weight of fresh rhizomes. However, the number of leaves remained uninfluenced. The highest yield was obtained with s2m3 treatment (10 t/ha rice husk biochar and 250 kg/ha NPK fertilizer). From this result, it can be suggested that the application of rice husk biochar in combination with Mahkota NPK fertilizer has the potential to remedy degraded alluvial soils and improve the growth and yield of ginger in the soils.

Abstract

The management of Artisanal and Small-scale Gold Mining (ASGM) in Sekotong Sub-district, West Lombok Regency, encounters considerable challenges due to environmental and social repercussions. These situations indeed need to be restored by conducting the mining activities sustainably. This study examined stakeholders' interactions and influences in the context of sustainable ASGM management by employing the MACTOR method. MACTOR is a method used to identify key actors, relationships between key actors, and their strategic objectives. Research data were obtained from structured interviews and field data, which were then processed to identify each actor's level of influence and dependence in the management of ASGM Sekotong. The results of the analysis showed DESDM, DLH, DIKOP, and DIKES as actors with high influence and low dependence. Meanwhile, miners and cooperative administrators were actors who had high influence and high dependence on the management of ASGM Sekotong. In addition, the level of convergence between DESDM and UNDP showed a commitment to sustainable practices of ASGM Sekotong, while the divergence of DESDM and miners highlighted the challenges in the management of ASGM Sekotong in aligning the goals of economic development and preserving the environment. This study emphasized the importance of strengthening the role of actors with low influence and reducing their dependence on dominant actors. Strong alliances among actors are essential to support the sustainable management of Sekotong ASGM. These findings provide strategic insights to formulate more inclusive and sustainable Sekotong ASGM policies and practices.
