Abstract

Low infiltration is one of the limiting factors on suboptimal land for agriculture. The infiltration is closely related to the soil's available water for plants. Low infiltration impacts soybean productivity. The contour planting system is a soil and water conservation technology that can be applied to increase infiltration. This research aimed to examine the impact of modifying the contour planting system on the infiltration characteristics of suboptimal land and soybean yields. The research used a quantitative approach with experimental methods (split-plot design) and three replications. The main plot treatment was the position of the land on the slope (the upper, middle, and lower). The subplot treatment was the contour planting system (standard contour planting system, 30o, 45o, and 60o from the contour line). Data were analyzed using analysis of variance and Duncan’s Multiple Range Test. The results showed that the modification of contour planting systems had no significant effect compared to the standard contour planting system in improving organic carbon content, bulk density, infiltration characteristics, and soybean plant height. The standard contour system resulted in higher soybean yields than the modification of the contour planting system. The position of the soil had a significant influence on soil properties, infiltration characteristics, plant height, and yields of soybeans. The soil characteristics, infiltration characteristics, and soybean yields resulting from standard and modification of contour planting systems showed suboptimal improvements. Therefore, further studies are needed to optimize the application of modification of contour planting systems to support the implementation of conservation agriculture systems.

Abstract

Rapid urbanization has accelerated the degradation of subak rice fields in Bali, manifested through pollution of irrigation channels and reduced agricultural productivity. This study assessed the extent and characteristics of land degradation in South Denpasar and formulated sustainable management strategies for restoring the ecological and cultural integrity of the subak system. The Logical Framework Approach (LFA) was applied to identify key problems, analyze causal relationships, and develop measurable strategies. Data were obtained through questionnaires, interviews, field observations, and document analysis. Results showed that approximately 87 hectares of subak land were lost within five years, driven by weak spatial enforcement, domestic and industrial waste pollution, and limited farmer regeneration. The study formulated five priority strategies: (1) enforcement of land use regulations, (2) economic incentives for conservation farming, (3) integration of Tri Hita Karana values, (4) farmer capacity building through digital technology and (5) improved irrigation maintenance. The research highlights that sustaining the subak system requires a multi dimensional management approach integrating ecological restoration, socio economic empowerment, and cultural revitalization. Adoption of this framework by local authorities can enhance urban land governance, strengthen farmer livelihoods, and preserve Bali’s cultural agricultural heritage amid ongoing urban pressures.

Abstract

Coastal rice fields often have sandy textures, high salinity, low organic matter, and frequent waterlogging caused by seawater intrusion. These conditions, together with fluctuating rainfall, alter soil chemical properties and negatively affect crop cultivation. This study aimed to evaluate soil chemical properties, assess water quality, and analyze their relationship with rice productivity in the coastal rice fields of Pangandaran, West Java, Indonesia. Composite soil samples were collected from areas of 5-7 ha and analyzed for their chemical properties. Water quality was assessed based on the levels of dissolved oxygen (DO), nitrate, phosphate, electrical conductivity (EC), and pH. Data were analyzed descriptively, and Principal Component Analysis (PCA) was applied to group the sampling points. The results showed that organic C and total N were low to moderate, while available-Si and exchangeable K+ were very low. In contrast, P?O?, exchangeable Na+, and exchangeable Mg2+ were very high, whereas cation exchange capacity (CEC) and exchangeable Ca2+ were low to moderate. Based on EC and water table depth, PCA grouped the 20 sampling points into three clusters: high salinity (points 16-19), waterlogging (points 2-7), and relatively normal conditions (points 1, 8-15, 20). Average rice productivity was 2.48 t ha-1 in cluster 1, less than 1 t ha-1 in cluster 2, and 3,63 t ha-1 in cluster 3. These findings highlight the need for site-specific land and water management strategies to sustain rice cultivation in coastal areas.

Abstract

The proposed National Capital Integrated Coastal Development (NCICD) Program envisions a Coastal Reservoir (CR) in the Tanjung Pasir waters of Banten, Indonesia, as a critical component to address pressing environmental challenges in the Jakarta Bay area. This multi-functional CR aims to secure raw water supply and mitigate saline water intrusion into coastal aquifers. A primary concern in the design and long-term viability of this CR is sedimentation, directly influenced by suspended sediment concentrations (SSC). This study presents a basic characterization of suspended sediment dynamics in the Tanjung Pasir waters. Utilizing a methodology encompassing in-situ sampling, laboratory analysis, and data interpretation, the findings revealed an average SSC of 89.31 mg/L, with a range of 5-200 mg/L. These concentrations align with Indonesian Government Regulation PP 22 of 2021, indicating suitability for various uses including aquaculture, tourism, and port activities. Notably, suspended sediment concentrations at the near-bed layer (0.8d) were marginally higher than those observed in the mid-depth (0.6d) and surface (0.2d) layers, suggesting a typical vertical distribution pattern influenced by hydrodynamic forces. This research produced very important empirical data as a basis for designing and validating action research on suspended sediment management, which aims to improve CR design parameters, predict sedimentation rates, and ensure the long-term operational sustainability of this infrastructure.

Abstract

Ensuring food security in the face of growing global demand and environmental constraints requires sustainable management of agricultural soils. Soil chemical fertility plays a critical role in crop productivity and, consequently, in the long-term capacity of agricultural systems to meet food demands. In this context, assessing the status of key soil nutrients, namely nitrogen, phosphorus, and potassium, is essential for guiding effective land management strategies. The municipality of Chebli was selected for this research. Eighteen composite soil samples were collected from the surface horizon (0-20 cm) and analyzed for major fertility indicators. The study evaluated the chemical fertility of agricultural soils using both the Nutrient Index classification and the Productivity Index. All soils exhibited low total N concentrations (0.10% to 0.23%). Available P concentrations ranged from 2.07 to 75.46 mg kg?¹, with a mean value of 19.70 mg kg?¹, while available K concentrations were low (<0.4 cmol kg?1). The Nutrient Index assessment classified the soils of Chebli as having moderate fertility with respect to organic matter and available phosphorus, and low fertility for nitrogen and potassium (NI pattern: MLML). In addition, the Productivity Index identified three distinct productivity classes, with a dominance of the moderate productivity class (PI between 41 and 60). These findings provide a scientific basis for developing site-specific fertilization strategies and sustainable soil management practices. Future research should focus on long-term monitoring and the use of organic amendments to enhance both soil fertility and crop productivity.

Abstract

Red chili consumption in Indonesia is recorded to increase by 6.78% or 40.42 thousand tons in 2024 from 1,650.75 thousand tons in 2022, while productivity in 2025 is projected to increase by 6.78%, while chili productivity in 2024 is 1,386.45 thousand tons. 37% of the land area in the Kesambi Sub-watershed is marginal and has potential for horticultural cultivation. The research aims to align land and chili cultivation management on the slopes of Mount Raung, Indonesia, toward sustainable agriculture and national food self-sufficiency. The method used is through data collection, both laboratory data and land biophysical data that are adjusted to match the suitability with plant growth requirements. The results of the study showed that the actual land suitability of red chili plants at 78.87% or 2,558.48 ha was dominated by the marginally suitable class (S3), and 21.13% or 685.58 ha were in the unsuitable category (N), with the most inhibiting factors being erosion hazards, nutrient retention, and air availability. Efforts to improve land quality to produce optimal production for crop achievement through the addition of agricultural fertilizers such as NPK, the provision of organic matter and dolomite, and slope improvement by making “gulud” terraces or providing mulch so that the potential land was achieved to 67.11% or 2,177.01 ha dominated by class S3, 21.13% or 685.58 ha were categorized as unsuitable class (N), and 11.76% or 381.47 ha were categorized as quite suitable class (S2).

Abstract

The Vietnamese Mekong Delta (VMD), Vietnam's “rice bowl”, is a vital agricultural hub due to its extensive network of rivers and fertile floodplains. This study evaluates land use/land cover (LULC) changes in the Upper Delta - Dong Thap Province from 1990 to 2023, using Landsat imagery and random forest algorithms. LULC maps were analyzed across five classes: cropland, wetlands, permanent crops, built-up areas, and open water. We monitored these classes at three points: 1990, 2005, and 2023, noting improvements in classification accuracy from 89% in 1990 to 94% in 2023. Significant transformations were observed; from 1990 to 2005, the most extensive change was the conversion of 477.32 km² of wetlands to cropland. Conversely, the minimal change involved only 0.55 km²  of open water area converted to built-up areas. Between 2005 and 2023, transitions from cropland to permanent crops dominated, peaking at 242.03 km². Over the three decades, the province experienced substantial shifts in LULC, primarily from wetlands to croplands, totaling 513.24 km². These changes reflect both natural dynamics and human impacts, underscoring the influence of past policies on land development. This longitudinal study provides crucial insights for policymakers, emphasizing the need for informed, sustainable land management strategies in Dong Thap Province.

Abstract

Sedimentation of small reservoirs is a critical factor in the degradation of land and water resources in the Sudano-Sahelian zone. Such infrastructure underpins agricultural resilience and rural livelihoods. This study used an integrated granulometric, morphometric, and spatial analysis to evaluate sediment accumulation in the Toukomtoré reservoir in Koubri, central Burkina Faso, and to inform degraded land management strategies. Ten sediment cores (maximum depth: 1.50 m) were collected along transects spanning the upstream-downstream and center-periphery axes. Thirty samples were analyzed for particle size distribution, and key parameters such as the Hazen uniformity coefficient (Cu) and the classification coefficient (Cc) were computed. Spatial interpolation was performed using QGIS, and statistical analyses were performed using R 4.4.3. The results indicate a mean sediment deposition of 90 cm, peaking at 119 cm in the upstream and central zones, which are dominated by sand (64%-80%). Subsurface layers are predominantly sandy (80%), while surface horizons show enrichment of silt and clay, indicating recent deposition. The bulk density ranged from 1.55 to 1.63 g/cm³. Critical degradation drivers include a steep watershed slope of 10.5 m/km, sparse vegetation, unsustainable tillage practices, and the absence of soil conservation structures. This sedimentation process severely reduces reservoir storage capacity and accelerates land degradation. To mitigate erosion and prolong infrastructure lifespan, this study recommends integrated watershed interventions, including vegetative buffers, check dams, and agroforestry. This study provides policymakers who manage small reservoirs in semi-arid, degraded landscapes with actionable data.

Abstract

Acid sulfate soils pose significant challenges for rice cultivation due to  their extreme acidity (pH<4.0) and associated nutrient deficiencies. This study investigated the effectiveness of biochar enriched with various organic amendments in improving soil properties and rice growth in degraded acid sulfate soils. A randomized block design was employed with seven treatments: control (B0), biochar enriched with Chromolaena odorata (B1), rice straw (B2), chicken manure (B3), cattle manure (B4), Tithonia sp. compost (B5), and NPK fertilizer at half the recommended dose (B6), each applied at 10 t/ha. The experiment was conducted under greenhouse conditions using 10 kg of soil per polybag with four replications. Soil samples from Sungai Kakap, West Kalimantan,  exhibited severe constraints, including pH levels of 3.75-3.87, organic carbon content of 0.82-0.98%, and high Al and Fe contents (>3%). Results demonstrated that organic matter-enriched biochar treatments significantly improved soil chemical properties (p<0.01). Rice straw-enriched biochar (B2) achieved the highest available P (117.93 ppm) and K (1.09 cmol(+)/kg), while cattle manure-enriched biochar (B4) showed maximum organic C increase (1.30%). Plant growth parameters showed significant improvement, with B2 producing the tallest plants (137.43 cm) and B5 (Tithonia sp.) yielding the highest productive tillers (38.83). The findings indicate that biochar enriched with local organic materials, particularly rice straw and Tithonia sp., offers a sustainable solution for rehabilitating degraded acid sulfate soils while enhancing rice productivity.

Abstract

Studying groundwater conservation zones is vital for maintaining groundwater sustainability. A model for groundwater conservation zones should be based on groundwater pollution vulnerability to ensure that groundwater resource sustainability addresses both quantity and quality. Still, few studies have been conducted on groundwater conservation zone models based on groundwater pollution vulnerability zones. This study used the modified GOD method to explore a groundwater conservation zone model based on groundwater pollution vulnerability zones. The research variables included groundwater depth, aquifer type, natural materials of the aeration zone, and land use. The data was collected through a field survey and literature reviews, and then processed using scoring and overlay techniques through geographic information system software. The results indicated that the modified GOD generated a model with better accuracy. The modified GOD produces a model of groundwater conservation priority zones with four classifications: groundwater conservation priority zone I is in areas with high pollution vulnerability; zones II and III are in areas with medium and low pollution vulnerability, respectively; and zone IV is in areas with no pollution vulnerability.
