Abstract

This study aims to identify and analyze the forms and contributions of integrating local wisdom into physics learning to improve students' scientific literacy. The background of this review is the low level of scientific literacy in Indonesia, as indicated by the 2018 PISA data, highlighting the need for contextual approaches in education, including the use of local wisdom. The method used is a systematic literature review guided by the PRISMA framework, involving identification, screening, eligibility, and inclusion of articles from Scopus, ERIC, and Google Scholar databases for the 2020–2025 period. From 19,534 documents initially identified, 15 articles were selected for in-depth analysis. The findings reveal that the forms of local wisdom integration include traditional tools, cultural ceremonies, local foods, traditional houses, and social values, all connected to physics topics such as motion, heat, pressure, and energy. This integration has been proven to enhance students’ scientific literacy across four dimensions: cognitive (conceptual understanding), procedural (scientific skills), affective (attitudes toward science and culture), and contextual (ability to relate science to real-life situations). The findings affirm that local wisdom holds significant potential as a relevant and humanistic learning approach aligned with the principles of the Merdeka Curriculum. This review is expected to serve as a foundation for developing more systematic and applicable models of physics learning based on local culture at the secondary school level.

Abstract

This study aims to predict the unemployment rate in Central Java Province using a linear regression method based on indicators of education level and economic growth. Secondary data from 2024, collected from various regencies and cities in Central Java, were analyzed to examine the relationship between the independent variables—education level and economic growth—and the dependent variable, unemployment rate. The analysis results show that an increase in the average years of schooling significantly reduces the unemployment rate, while economic growth also contributes to lowering unemployment, although its effect is smaller and varies across regions. The developed linear regression model is able to explain most of the variation in the unemployment rate and is used to project unemployment trends up to 2027, with a predicted decline in unemployment, assuming continued improvement in education quality and stable economic growth. These findings emphasize the importance of synergy between enhancing education quality and inclusive economic growth as key strategies to reduce unemployment in Central Java. However, unemployment is a complex issue influenced by other factors such as infrastructure, regional policies, and workforce readiness, thus requiring a comprehensive approach. This study is expected to provide a foundation for formulating more targeted policies to alleviate unemployment in the region.
