Abstract

Flood inundation around Rawa Pening Lake has intensified in recent years, yet long-term patterns of inundation extent and persistence remain poorly quantified. This study aims to analyse the interannual and spatial dynamics of flood inundation in the Rawa Pening lake-basin system during 2019–2025 and to identify riparian zones that experience recurrent flooding. Sentinel-2 Level-2A imagery was processed within a 3 km riparian buffer to compute the Modified Normalized Difference Water Index (MNDWI), apply a histogram- and visually based threshold for water extraction, and generate annual maximum inundation and seasonal wet-season inundation-frequency metrics. The classification achieved high overall accuracy (93.1%), supporting the reliability of the derived inundation products. The multiyear results reveal strong year-to-year variability in maximum inundation and show that floodwater consistently concentrates in low-lying southern and southeastern riparian sectors, particularly within Banyubiru and Tuntang subdistricts, while western and northern sectors experience smaller and less persistent flooding. The combination of maximum inundation extent and inundation-frequency maps provides complementary insight into extreme events and recurrent flood exposure, enabling a clearer distinction between episodic and chronic flood impacts on riparian agriculture and settlements. These findings demonstrate the value of multitemporal MNDWI analysis and an ecologically defined buffer zone for monitoring lake-basin flooding and offer a spatial basis for prioritizing riparian conservation, land-use regulation, and flood-risk reduction around Rawa Pening.

Abstract

Critical thinking skills are essential for students not only to understand the material but also to solve everyday problems based on their knowledge. These critical thinking skills can be further developed when teachers create a learning environment that supports students in honing their critical thinking abilities, especially in learning geography. Student self-motivation is also a crucial aspect of successful learning. The integration of digitalization in education should be maximally utilized to enhance students' motivation and interest in learning geography. Augmented reality (AR) is one of the alternative digital technologies that can be used as a learning media. This study employed a quantitative approach with a quasi-experimental design using a pretest-posttest control group model. Data collection techniques included observation to assess the geography learning conditions at the research site, tests to measure students' critical thinking skills, questionnaires to determine students' motivation levels, and documentation. Data analysis techniques used were normality test, homogeneity test, N-Gain test, and descriptive percentage analysis. The results indicated that the model and media used were less effective in improving critical thinking skills, as evidenced by a low average N-Gain score of 0.0392 in the experimental class. Meanwhile, student learning motivation increased slightly by 0.33%, from 72.74% to 73.07%, which is categorized as high motivation.
