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.
