Abstract

Enhancing the quality of education involves fostering strong literacy skills, not only in academic aspects but also in understanding, processing, and conveying information. In the midst of globalization and technology, literacy skills have become increasingly important in facing the changes of the times. This study aims to develop a playful learning approach that encourages enjoyable literacy activities in Desa Sokawati. Employing a qualitative approach with an action research design, this study engages children, educators, parents, and the community in Desa Sokawati. Engaging literacy activities tailored to the characteristics of children are designed based on surveys and interviews. Once planned, these literacy activities are implemented in KB, TK, and SD classes. Observations of children's and educators' responses are conducted during the implementation phase. The results indicate that the playful learning approach is effective in fostering enjoyable literacy activities in Desa Sokawati. Children are engaged in various activities that combine creativity, art, and learning. By developing an approach that suits the characteristics of children and the local potential, this study aims to provide practical guidance for educators, parents, and the community in enhancing children's literacy in Desa Sokawati. Furthermore, this research contributes to the development of sustainable literacy-based education in rural areas.

Abstract

Understanding predictive relationships between oceanic conditions and extreme rainfall is crucial for improving weather forecasting capabilities in tropical maritime regions. This study investigates quantitative relationships between precipitation, chlorophyll-a concentrations, and extreme rainfall patterns in West Java using 10 years of satellite observations (2014-2024). We analyzed IMERG precipitation data and MODIS chlorophyll-a products using cross-correlation analysis, continuous wavelet transform, cross-wavelet coherence, and spatial extreme indices calculations. Results reveal statistically significant coupling between precipitation and chlorophyll-a (r = -0.173, p < 0.001) with precipitation leading chlorophyll decrease by 19 days, reflecting marine ecosystem responses to terrestrial runoff. Cross-wavelet coherence analysis demonstrates 78% annual coherence and 68% semi-annual coherence between these variables, with 72.5% of total variance explained by significant periodic interactions. Wavelet analysis identifies dominant annual and semi-annual cycles in both precipitation and chlorophyll-a with 95% statistical significance. Spatial analysis using k-means clustering reveals four distinct precipitation regimes: northern coastal zones with prolonged dry periods (>45 days), central highlands with intense convective activity (>3000 mm annually), southern mountains with extreme precipitation (>3200 mm), and transitional zones with mixed characteristics. Spatial autocorrelation analysis confirms significant clustering (Moran's I = 0.65-0.89) of precipitation extremes across the region. The identified 19-day lead-lag relationship provides a scientific foundation for marine ecosystem monitoring and represents a significant advancement in understanding ocean-atmosphere-ecosystem coupling processes in tropical Indonesia. These findings have important implications for developing improved seasonal forecasting capabilities and ecosystem-based climate adaptation strategies.
