Abstract

This study aims to evaluate the effect of learning media on the learning motivation of Vocational High School (SMK) students. The method used in this study is a meta-analysis with data collected through Google Scholar and Semantic Scholar in September 2025. The search keywords used Indonesian with a combination of the variables "learning media" (animation, video, PowerPoint, and teaching modules) and "learning motivation of vocational high school students". The data analyzed were in the form of Effect Size (ES) and Standard Error (SE) values ​​to produce a forest plot containing interval coefficients in each study. Calculations of heterogeneity, publication bias, and fail-safe N were also carried out to ensure the validity of the results. Of the 79 articles searched, 20 articles met the criteria for analysis. The results of the meta-analysis showed that learning media had a significant effect on student learning motivation with a summary effect of 0.849, z = 7.399, p < 0.001, and a 95% CI interval coefficient [0.624; 1.074]. Heterogeneity analysis yielded Q = 1065.072 with p < 0.001 and I² = 97.18% indicating a very high variation between studies. Subgroup analysis based on expertise program showed that Accounting and Finance had a value of -0.161 (95% CI [-0.617; 0.295]), while Automotive Engineering was 0.072 (95% CI [-1.081; 1.225]). Both were insignificant, as p > 0.05. Subgroup analysis based on learning media type also showed insignificant results: animation = 0.225 (95% CI [-1.020; 1.470]), teaching module = -0.125 (95% CI [-0.776; 0.526]), PowerPoint = 0.110 (95% CI [-0.574; 0.794]), and video = 0.215 (95% CI [-0.428; 0.859]). The Egger test showed a p value of 0.662, indicating no indication of publication bias. Furthermore, the fail-safe N value of 10,614 far exceeded the threshold of 110, confirming the reliability of this study. Overall, these findings emphasize the importance of utilizing learning media in increasing vocational high school students' learning motivation, although the effectiveness of specific media types still requires further study.

Abstract

The global energy crisis has become one of the major challenges facing the world today. The increasing demand for energy, limited fossil fuel resources, and negative environmental impacts are driving the need to seek sustainable and environmentally friendly energy solutions. Renewable energy conversion, such as solar, wind, hydroelectric, biomass, and geothermal, offers great potential as an alternative source of clean and renewable energy. This is literature review studdy. This article explores the important role of renewable energy conversion in addressing the global energy crisis and mitigating climate change. By analyzing the technology, policies, economic, social, and environmental aspects related to renewable energy conversion, this article highlights environmentally friendly solutions that can support a sustainable energy transition and ensure future energy security. Furthermore, this article discusses the challenges and opportunities in integrating renewable energy into the energy system, as well as the importance of public participation and co-ownership models in renewable energy projects.
