Abstract

The development of retail centres in Tuban District significantly affects urban road performance. This study aims to analyze traffic volume and the degree of saturation (DS) around four major supermarkets: Citimall, Bravo, Samudra, and Keraton. Primary data were collected through field surveys on Mondays, Fridays, and Sundays during peak hours. Analysis using PKJI 2023 guidelines shows that Citimall has the highest traffic volume and DS of 0.673 on Sunday evenings. Statistical testing with One-Way ANOVA indicates a significant difference in traffic impact between locations (p < 0.001). Five-year projections using linear regression suggest that DS values at critical points, such as Citimall, will exceed capacity (DS > 1.0) without intervention. GIS mapping provides a visual representation of saturation hotspots, aiding in strategic traffic management.

Abstract

Slope stability in hilly areas with high seismic activity requires thorough geotechnical assessment to prevent potential failures that could endanger infrastructure and human safety. This study evaluates the effectiveness of soil nailing combined with shotcrete in reinforcing slopes under both static and seismic conditions at JLS Lot 3, Blitar. A two-dimensional finite element method (FEM) with plane strain modeling was applied to simulate slope behavior, including staged construction procedures and soil-structure interaction. Soil parameters were derived from bore log data, corrected for groundwater table and overburden effects, and used to define unit weight, cohesion, internal friction angle, modulus of elasticity, and Poisson’s ratio. The slope geometry was carefully modeled with attention to benching, slope angles, and shotcrete coverage. Surface loads representing construction, traffic, and pavement conditions were applied to the model to reflect realistic field scenarios. Results show that, without seismic loading, the reinforced slope reached a safety factor of 1.575, exceeding the minimum criterion of 1.50. When seismic loading was applied, the safety factor decreased to 1.106 but remained above the required 1.10 threshold, demonstrating that soil nailing with shotcrete effectively improves slope stability and controls deformation. The study emphasizes the importance of reinforcement design parameters, such as nail length, spacing, inclination angle, and shotcrete thickness, providing insights for optimizing slope reinforcement strategies under seismic conditions. The findings contribute to safer and more resilient slope design practices in earthquake-prone areas.

Abstract

Retaining walls play a crucial role in road and bridge infrastructure by resisting lateral earth pressure and preventing slope failure or damage caused by rising river water levels. This study compares the stability of gabion-type and cantilever-type retaining walls through manual calculations and numerical simulation using Geo5 software. The analysis focused on overturning, sliding, bearing capacity, and slope stability under both normal and flood water level (MAB) conditions. Manual calculations indicated that both wall types satisfied stability requirements with safety factors of 0.96–2.07 for overturning, 2.01–3.53 for sliding, and 6.89–6.92 for bearing capacity. However, Geo5 analysis showed that gabion walls were only safe in terms of overturning (6.70–7.50) and sliding (2.12–2.30), while bearing capacity (0.57–0.80 < 3.0–3.5) and slope stability (1.33–1.37 < 1.5) did not meet the required standards. In contrast, cantilever walls proved safe across all parameters, with safety factors of 7.25–9.87 for overturning, 2.09–2.48 for sliding, 3.14–4.90 for bearing capacity, and 1.52–1.69 for slope stability. Therefore, reinforced concrete cantilever retaining walls are more suitable as an effective and reliable alternative to gabion walls, particularly in flood-prone and landslide-prone areas.

Abstract

Road pavement deterioration significantly reduces service performance, driving comfort, and traffic safety, making accurate pavement condition evaluation essential for effective maintenance planning. This study aimed to assess pavement condition using the Pavement Condition Index (PCI) method and to map the spatial distribution of pavement distress using Geographic Information Systems (GIS) along the Gayam–Sidorejo road segments in Kediri Regency, Indonesia. Data were collected through field surveys by identifying the type, severity, and dimensions of pavement distress in each sample unit. For systematic analysis, the road was divided into nine segments. PCI values were calculated based on deduct value (DV) and corrected deduct value (CDV) procedures. The results showed that the average PCI value was 48.09, indicating poor pavement condition overall. The lowest PCI value was recorded in Segment 6 (36.2), which was categorised as very poor and requiring structural rehabilitation, while the highest PCI value was recorded in Segment 9 (63.0), which was categorised as fair and requiring routine maintenance. GIS-based mapping using ArcGIS effectively visualized the spatial distribution of pavement conditions across the study area. These findings provide useful information for identifying maintenance priorities and supporting more effective pavement management strategies.

Abstract

This study investigates the extent of intrusion in the Kenjeran coastal aquifer, Surabaya, Indonesia, through an integrated geophysical approach. Four one-dimensional Vertical Electrical Sounding (VES) surveys and two two-dimensional Electrical Resistivity Tomography (ERT) transects were conducted using Schlumberger and Wenner–Schlumberger configurations to obtain both depth-specific and laterally continuous resistivity data. The 1D VES results detected low-resistivity layers (<1.0 Ω·m) at depths exceeding 58–66 m, indicating deep saline groundwater. The 2D ERT sections identified wedge-shaped low-resistivity anomalies (0.1–0.8 Ω·m) at depths of 7.5 m to 48 m, indicating active intrusion progressing inland. Intrusion is more severe in the northern sector, with vertical penetration up to 48 m and horizontal encroachment beyond 200 m from the shoreline. The integration of 1D and 2D resistivity imaging proved effective in delineating saline–freshwater interfaces, enabling targeted mitigation measures and informed groundwater management to safeguard Kenjeran’s aquifer from further degradation.

Abstract

The study of shoreline changes at Pulau Merah Beach, Banyuwangi, highlights that this coastal tourism area is highly dynamic due to the influence of ocean waves, currents, and the deposition of sand and silt. Monitoring shoreline changes is essential to ensure that the tourism area remains safe, well-managed, and sustainable. This research aims to analyze the patterns of shoreline shifts from 2016 to 2025 and to distinguish between areas experiencing continuous erosion and those affected only occasionally. The data were obtained from Landsat 8 satellite imagery, which was processed using the Normalized Difference Water Index (NDWI). Ten observation lines (transects) with a spacing of approximately 100 meters were established, and annual shoreline shifts were measured using the Euclidean Distance method. The results show that some sections of the shoreline experience continuous erosion, particularly transects 1–4, which retreated almost every year by a considerable distance. Meanwhile, transects 6–9 were eroded only at certain times and later stabilized, while transects 5 and 10 displayed mixed patterns. This study demonstrates that transect analysis combined with the Euclidean Distance method is effective in monitoring shoreline changes over time. Overall, shoreline changes at Pulau Merah are significant and uneven, requiring focused management on areas with continuous erosion, while other areas should be monitored regularly and strengthened through coastal vegetation.

Abstract

Coastal shoreline change is a complex natural phenomenon that can cause significant impacts on coastal areas, such as land loss, infrastructure damage, and disruption of the community’s socio-economic activities. These impacts can be minimized if shoreline change monitoring is carried out periodically in vulnerable areas. Lamongan Regency, with its relatively long coastline, is an area highly susceptible to shoreline changes caused by abrasion and accretion. Therefore, research related to the dynamics occurring in this region is necessary. This study aims to identify shoreline change phenomena along the coast of Lamongan Regency during the 2016–2025 period. The method used in mapping shoreline changes involved processing Landsat 8 satellite imagery using NDWI in ArcGIS, followed by distance calculations using the Euclidean distance method and the Haversine formula, as well as conducting a statistical T-test on the results of both methods. The statistical two-sample T-test with equal variance indicated that there is no variance difference between the results obtained using the Euclidean distance method and the Haversine formula. Based on the calculation results, it was found that the greatest shoreline change due to abrasion during 2016–2025 occurred at Transect 1, specifically in Lohgung Village, Brondong District, with a change of 81.51 meters. Meanwhile, the greatest shoreline change due to accretion occurred at Transect 20, precisely in Kranji Hamlet, Paciran District, with a change of 92.00 meters.

Abstract

Flooding is one of the most frequent hydrometeorological disasters in Indonesia and continues to threaten urban areas due to rapid land-use changes, increasing impervious surfaces, and inadequate drainage systems. Malang City, East Java, has experienced rapid urban development that increases flood susceptibility in several districts. Therefore, identifying flood-prone areas and determining appropriate evacuation routes are essential components of disaster risk reduction.This study aims to identify flood-prone areas and determine optimal flood evacuation routes in Malang City using Geographic Information Systems (GIS). The analysis integrates several physical parameters affecting flood susceptibility, including rainfall, land use, slope, soil type, and topographic conditions. Spatial analysis was conducted through thematic map overlay techniques to produce flood susceptibility zoning. Furthermore, road network analysis was employed to identify the shortest and safest evacuation routes from flood-prone locations to designated evacuation points.The results are expected to provide flood hazard maps classified into several susceptibility levels and evacuation route maps that support emergency response planning. These outputs can serve as references for local governments in improving flood mitigation strategies, spatial planning, and disaster preparedness. The application of GIS demonstrates its capability to integrate spatial datasets for hazard assessment and evacuation planning, providing an effective decision-support system for sustainable urban disaster management.

Abstract

Residential water ponding has become a recurring problem in Lamongan District, Indonesia, disrupting residential activities and increasing flood risk. Accurate spatial identification of vulnerable areas is essential to support effective urban planning and drainage management. This study aims to map residential water ponding vulnerability using a Geographic Information System (GIS) and the Weighted Overlay Analysis. Five parameters, namely rainfall, slope, soil type, land use, and drainage conditions, were processed using ArcGIS through scoring, weighting, and spatial overlay techniques. A field questionnaire survey was also conducted to validate the spatial analysis results. The analysis classified the study area into four vulnerability levels: Low, Moderate, High, and Very High. The High vulnerability class dominated the study area, covering 37.14%, followed by Moderate (32.90%), Very High (25.41%), and Low (3.64%). Questionnaire results confirmed that water ponding frequently occurs in several residential areas, with respondents identifying high rainfall, inadequate drainage capacity, and blocked drainage channels as the primary contributing factors. The consistency between GIS analysis and field observations indicates that the proposed approach provides reliable spatial information for identifying priority areas for flood mitigation. The resulting vulnerability map can support evidence-based urban planning and sustainable drainage management in Lamongan District.
