Abstract

Concrete roof tile are widely used as roofing material due to its durability and performance. However, concrete roof tiles have relatively high weight and their production cost limit broader application. This study aims to develop an environmentally friendly lightweight concrete roof tile by adding styrofoam waste as a partial substitute for fine aggregates in the mortar mix. Four percentage variations of styrofoam content were used in making mortar and roof tile samples, which are 0%, 4%, 8%, and 12% relative to the total volume of sample. These variations were chosen to investigate the effect of styrofoam addition on the mechanical and physical properties of mortar and concrete roof tiles. A series of tests were also conducted, such as compressive, tensile, and flexural strength tests of mortar, flexural strength of roof tiles, as well as impermeability and porosity tests of the final products. The results of these tests indicate that the optimal mechanical performance was achieved at 8% styrofoam content, with mortar flexural strength reaching 5.05 MPa and roof tile flexural strength at 4.58 MPa. Although compressive strength declined with increasing styrofoam content, values remained within acceptable limits for non-structural applications. All roof tile samples met the impermeability criteria based on SNI 0096:2007, which states that there must not be water seepage through the samples for approximately 20 hours ± 5 minutes, regardless of their styrofoam content. Finally, it can be concluded that styrofoam can be effectively repurposed as an additive in concrete roof tile production, resulting in a lightweight, cost-effective, and sustainable building material.

Abstract

Canggu Beach, Bali, is a multifunctional coastal area that faces environmental pressures due to erosion and rapid coastal development. This study analyzed shoreline changes during the period 2016-2024 using multitemporal Sentinel-2 satellite images processed through the Google Earth Engine (GEE) platform. Shoreline extraction was performed using NDWI index and Otsu threshold method, with sea level stability control based on HYCOM data. Shoreline change analysis was conducted using Digital Shoreline Analysis System (DSAS) on 247 transects with Net Shoreline Movement (NSM) and End Point Rate (EPR) approaches. Results showed a dominant trend of accretion (NSM +16.61 m; EPR +2.26 m/year), with localized erosion (NSM -8.8 m; EPR -1.2 m/year), identified around estuary and structured areas. Spatial patterns of change were visualized in the form of multitemporal maps and statistical histograms, revealing uneven shoreline dynamics. The integration of GEE and DSAS proved effective for large-scale shoreline monitoring, and the results can provide a basis for adaptive coastal management in dynamic, multi-functional coastal areas.

Abstract

The rapid expansion of industrial and nickel mining activities in Central Halmahera has driven dynamic changes in land use, often leading to conflicts with established spatial plans. This study identifies land use deviations from the North Maluku Provincial Spatial Plan (2024–2043) using spatial analysis techniques. Through the overlay method, recent land use and land cover data (from 2022) were compared with the designated spatial zoning plan. The analysis results show a generally high level of compliance, with approximately 98.13% of the total 247,596.80 hectares aligning with the spatial zoning plan. However, significant deviations were found in the Mangrove Zone (17.94%) and Marine Conservation Zone (47.98%) due to settlements and infrastructure development. These changes are driven by industrial growth, a surge in the workforce, and increased demand for housing and services. The findings reveal real challenges in the effectiveness of spatial planning instruments to control land use changes. Emphasis on the need for proactive and integrated spatial governance can be addressed through stricter zoning regulation enforcement, continuous monitoring, and active community involvement in the planning process to ensure sustainable land management amid ongoing extractive industry expansion.

Abstract

This study analyzes irrigation water quality and evaluates dryland suitability in Abang District, Karangasem Regency, Bali Province, using two assessment models: the National Sanitation Foundation Water Quality Index (NSF-WQI) and the Index of Surface Water Vulnerability to Pollution (IKAPP). Water samples from six irrigation points along Tukad Nyuling were analyzed for physical and chemical parameters, while rainfall, land use, and population density were integrated through spatial analysis. The results show that NSF-WQI values ranged between 69.96–79.78, indicating moderate to good irrigation quality, while the IKAPP average value of 23.69 represented a low vulnerability level. Spatial variation was influenced by topography, soil permeability, and land cover distribution. The integration of NSF-WQI and IKAPP provides a reliable framework for site-specific irrigation management, supporting sustainable dryland agriculture in tropical environments.

Abstract

This study investigates the relationship between railway travel service characteristics and passenger demand on the Rangkasbitung – Merak commuter rail corridor. Secondary data on passenger volumes were obtained from PT Kereta Commuter Indonesia, while primary data were collected via on-board surveys conducted across multiple afternoon trips. Descriptive statistical analyses were performed to determine key performance indicators—namely load factor, travel time, dwell time, and commercial speed against established service standards. Subsequently, a binary logistic regression model was employed to assess the influence of travel cost and travel time on passengers’ likelihood to choose electric commuter services over conventional local trains. Results reveal an average load factor of 2.40, indicating the existing service capacity is frequently exceeded during peak periods. Average dwell times ranged between 2–5 minutes per station, and observed commercial speeds fell below the stipulated benchmark. Logistic regression analysis showed that travel cost (p = 0.316) did not exert a statistically significant effect on mode choice, whereas travel time emerged as a significant determinant: improvements in travel time increased the probability of passengers opting for electric commuter services by approximately 72.1%. These findings suggest that enhancing operational speed and optimizing station dwell times are critical to meeting passenger demand and improving overall service attractiveness on the Rangkasbitung – Merak route.

Abstract

Higher education institutions in developing nations are growing swiftly to address the increasing demand for quality education; however, their physical infrastructures frequently lack adequate evaluation regarding safety, functionality, and environmental performance. This study focuses on the Education and Humanities Building at Far Western University (FWU) in Nepal, two main academic structures built in the early 2010s that have been in continuous use without maintenance. A mixed-methods strategy was utilized, including visual assessments, non-destructive testing (NDT) using a rebound hammer, physical measurements, user surveys, and a review of secondary data. The results indicate moderate material strengths (14.46 MPa for masonry walls, 17.0 MPa for masonry columns, and 17.4–26.63 MPa for slabs), which are typical of older institutional buildings, but there are significant issues such as cracks, moisture infiltration, corrosion, and the lack of expansion joints. Assessments of indoor environmental quality revealed high thermal discomfort, as the temperatures of second-floor slabs exceeded 50 °C, inadequate ventilation due to low window-to-wall ratios (<20%), and insufficient daylighting. User surveys (n=50) revealed ongoing issues concerning structural cracks, congested circulation areas, leaking roofs, and poor maintenance, all of which adversely impact safety and learning environments. The results emphasize the critical necessity for preventive maintenance, structural upgrades, and functional enhancements to comply with Nepal National Building Code (NBC) standards and international guidelines for healthy educational settings. By merging technical evaluations with user feedback, this research offers evidence-based suggestions for improving the resilience, safety, and sustainability of higher education infrastructure in regions of far western Nepal that are prone to seismic activity.

Abstract

In recent years, the Indonesian government has been aggressively pursuing toll road development. Infrastructure projects such as toll roads are known to stimulate economic growth and enhance the mobility of goods and people. This economic growth and increased mobility, in turn, accelerate the process of urbanization. Areas surrounding toll roads, particularly near access points and interchanges, often undergo land use conversion towards functions with higher economic value. Consequently, the presence of a toll road generates a multiplier effect on the surrounding region, encompassing both positive and negative impacts. The Trans-Java Toll Road, a major project connecting the western and eastern ends of Java Island, has been under development for a considerable period. Construction began in 1984, with the connection to Surabaya completed in 2018. Currently, the toll road extends to Probolinggo and is planned to reach Banyuwangi by 2025, spanning a total length of 1,167 km. This study aims to investigate the land cover changes resulting from the construction of the Trans-Java Toll Road, from Merak in the west to Probolinggo in the east of Java. This research employs a quantitative approach, utilizing spatial analysis and descriptive statistics within the Google Earth Engine platform to identify and analyze these land cover changes. This study reveals significant and consistent land cover transformations across the seven analyzed interchanges. Key findings from 1990 to 2020 indicate a universal increase in built-up areas, most substantially observed at the Surabaya interchange, which experienced a 17,681.09 Ha expansion of built-up land. This growth largely occurred at the expense of green areas, which decreased by 15,898.91 Ha in Surabaya and 8,102.97 Ha in Semarang. The Tangerang interchange also showed significant urbanization, with a 3,596.00 Ha increase in built-up land. These findings can serve as a crucial reference for anticipating and mitigating the potential negative consequences of future toll road projects, particularly as the government intensifies infrastructure development in regions outside of Java.

Abstract

The 2004 tsunami disaster caused severe ecological damage in Banda Aceh City, destroying a vast majority of its vegetation cover. This study aims to analyze the spatio-temporal dynamics of post-disaster vegetation recovery over two decades (2004-2024) to identify the stages of ecological succession. Using a remote sensing approach, Landsat satellite imagery from 2004 (pre-tsunami), 2005 (post-tsunami), 2014 (one decade later), and 2024 (two decades later) was analyzed using the Normalized Difference Vegetation Index (NDVI). The NDVI classification results show a drastic change: the non-vegetated area surged from 67.58% in 2004 to 89.01% in 2005, while the dense vegetation class was entirely eliminated. However, a recovery process unfolded over the subsequent two decades. By 2024, the non-vegetated area had drastically shrunk to just 13.11%, while the combined area of moderate and dense vegetation surged to over 45% of the city's total area, surpassing the pre-tsunami condition. This study concludes that Banda Aceh has not only successfully restored its vegetation cover but has also undergone a significant ecosystem maturation phase. These findings provide a robust scientific basis for integrating NDVI analysis as a proactive monitoring instrument into the Banda Aceh City Spatial Plan (RTRW) to support sustainable and disaster-resilient urban development.

Abstract

The development of multi-story buildings on soft soils poses significant challenges in geotechnical design, particularly in tropical regions such as Gorontalo, Indonesia. The development of multi-story buildings on soft soils poses significant challenges in geotechnical design, particularly in tropical regions such as Gorontalo, Indonesia. This study investigates the behavior of bored pile foundations with varying diameters (0.60 m, 0.80 m, and 1.00 m) using the finite element method (FEM) via PLAXIS 2D. The simulation integrates in-situ soil investigation data, including SPT and laboratory tests, with a staged construction model to evaluate total deformation and stress distribution. The borehole profile revealed predominantly silty and silty sand layers with high compressibility and low bearing capacity, requiring precise analysis to mitigate settlement risks. Two loading stages were analyzed: (1) pile installation and (2) column load application with a maximum load of 3,363.3 kN per column. Results show that increasing pile diameter significantly reduces vertical displacement. During pile installation, the total deformation was 4.37 mm for the 0.6 m pile, 4.68 mm for the 0.8 m pile, and 4.19 mm for the 1.0 m pile. Under full column load, displacement reached 35.3 mm (0.6 m), 29.6 mm (0.8 m), and 29.4 mm (1.0 m), respectively. Total stress analyses revealed more concentrated stress beneath the smaller piles and more diffused stress in larger piles. The 1.0 m pile showed the best performance, but the 0.8 m pile offered a comparable result with better material efficiency. This study supports the use of FEM for foundation optimization and provides technical guidance for sustainable infrastructure in soft soil regions.

Abstract

The signalized intersection of Jl. HR. Soebrantas – Jl. SM. Amin is one of the congestion-prone intersections in Pekanbaru City, particularly due to its location in a peatland area. Peatland conditions, which are characterized by low bearing capacity and high compressibility, limit extensive physical expansion of road infrastructure. At the same time, this intersection serves as a key connector between major activity centers, including educational institutions, offices, commercial areas, and residential zones, resulting in significant traffic congestion and long queues, especially during peak hours. To address these challenges, this study proposes the implementation of a Continuous Green-T (CGT) intersection design as an operational and geometric solution that minimizes the need for large-scale infrastructure modification. The objective of this study is to evaluate the performance of the intersection after the implementation of the CGT design using microscopic traffic simulation with VISSIM. The analysis results indicate that the existing condition has an average delay of 62.5 seconds (Level of Service/LOS F), while the implementation of CGT reduces the average delay to 19.3 seconds (LOS C). This demonstrates that the CGT design is effective in reducing intersection delay by 43.2 seconds and improving the Level of Service from F to C, making it a suitable approach for traffic management in physically constrained environments such as peatland areas.
