Abstract

Several locations along the Bulango River are utilized by the community for sand mining. The decline in river water quality is one of the impacts of sand mining on the environment. The purpose of this study was to determine the impact of sand mining on the physical quality of water in the Bulango River, North Bulango District, Bone Bolango Regency. Analysis of physical parameters carried out in the field, namely temperature, light intensity, and total suspended solids which was carried out in the laboratory. The results showed that the total suspended solids (TSS) at location II and location III at sunny weather were higher than at location I. Light intensity at location II and location III was lower than at location I. TSS parameters during rainy weather at location I, location II, and location III exceed the quality standards for classes 1 to 4. When the weather is sunny, the TSS values for locations II and location III exceed the quality standards for classes 1 and 2.

Abstract

Mobile augmented reality (AR) has evolved from an experimental visualization tool into a mature pedagogical medium that redefines spatial learning in geography education. By embedding digital content into authentic locations, AR fosters experiential and inquiry-driven learning aligned with geography’s spatial and environmental paradigms. Building on evidence from 2015 to 2025, this review synthesizes 138 studies to examine how AR supports cognitive, affective, and behavioral learning dimensions. The analysis reveals that AR enhances spatial reasoning, visualization of abstract processes, and place-based engagement when integrated within robust instructional design frameworks. However, persistent gaps remain in long-term learning assessment, scalability, and teacher competence for authoring AR experiences. Cognitive-load and motivation studies suggest that AR’s benefits are maximized when interactivity and spatial anchoring are balanced with scaffolding. The review proposes a multidimensional model linking technological affordances, pedagogical strategies, and geographic thinking to promote education for sustainability and digital spatial citizenship. Implications for researchers, educators, and developers are discussed to guide future cross-disciplinary innovations.

Abstract

This study was motivated by the high risk of flooding in the transmigration area of Taluditi Subdistrict, which is influenced by land-use changes, topographic conditions, and rainfall. This study aims to map flood risk levels and enhance community understanding of disaster mitigation. The methodology employed is a descriptive quantitative approach based on Geographic Information Systems (GIS), utilizing spatial analysis and SWOT analysis through field observations, questionnaires, and interviews. The research results indicate that high-risk areas are located in low-lying regions near river channels with inadequate drainage systems. Internally, the region possesses strengths in social aspects and natural resources, while externally, there are opportunities for government support despite facing the threat of climate change. These findings underscore the importance of integrating spatial analysis and community empowerment in sustainable disaster mitigation efforts.

Abstract

Flood is one of the most frequent hydrometeorological disasters in Indonesia and causes various impacts on the environment, infrastructure, and community livelihoods. Bulawa District, Bone Bolango Regency, is one of the areas with a high potential for flood hazards due to its topographic conditions, high rainfall intensity, and land-use changes. This study aims to map the spatial distribution of flood-prone areas in Bulawa District using a geospatial approach based on Geographic Information Systems (GIS). The data used in this study include rainfall, slope, river networks, land use, soil type, and elevation, which were processed using ArcGIS 10.8. The results indicate that flood hazard levels in Bulawa District are classified into three categories: low, moderate, and high. Areas with a high level of flood hazard are generally located in the southern part of the district, which is adjacent to coastal areas, while most other regions fall into the low-hazard category. Geospatial analysis revealed that rainfall, land use, and proximity to river networks are the main factors influencing flood hazard levels in the study area. The resulting flood hazard map can serve as a valuable reference for spatial planning, disaster mitigation, and regional development policy-making aimed at reducing flood risks in Bulawa District., and regional development policies aimed at reducing flood risk in Bulawa District.
