Abstract

This study explores the strategic integration of play therapy within early childhood education management as a means to promote inclusive education and holistic child development. Drawing on a qualitative secondary data analysis of policy documents, academic literature, and theoretical models, the research identifies key frameworks, challenges, and sustainable strategies for embedding therapeutic interventions in school systems. Findings suggest that play therapy contributes significantly to emotional regulation, social inclusion, trauma recovery, and individualized learning—core components of equitable education. However, the institutionalization of play therapy faces various barriers, including policy gaps, resource limitations, staff training deficits, and cultural stigma surrounding mental health. The paper concludes with a set of actionable recommendations for educational leaders and policymakers to build systemic readiness and long-term sustainability through cross-sectoral collaboration, curriculum alignment, and inclusive leadership practices.

Abstract

This research explores the application of the Adaptive K-Means clustering algorithm on Human Development Index (HDI) data across 34 provinces in Indonesia, comparing the performance of Euclidean and Divergence distance metrics. The HDI indicators used include life expectancy, years of schooling, and per capita expenditure. Data processing was conducted both manually on sample data and automatically using Python for the complete dataset. Results demonstrate that the choice of distance metric significantly impacts clustering effectiveness. Divergence outperformed Euclidean based on silhouette score evaluations, offering more representative cluster separation. Scatter plot visualizations tracked the iterative clustering process. The study contributes to optimizing clustering techniques for socio-economic indicators such as HDI.

Abstract

The development of science and technology facilitates various aspects of life, including forecasting. Forecasting student enrollment in private universities can maximize the use of resources for services, facilities, infrastructure, and improving human resources. The regression method is used to measure the effect of promotional costs on increasing student enrollment in the future. This forecasting will be valid if an accurate model is used. The results showed the level of accuracy using the MAPE (Mean Absolute Percentage Error) model of 2.229%. However, the level of accuracy can vary each due to differences in data.
