Abstract

Climate change is a global long-term change in temperatures and weather. Climate change is a worldwide issue that requires proper handling to reduce the negative impact on humans and the environment. Analyzing historical data is beneficial for studying climate change. Machine learning and deep learning methods are useful tools for data analysis. The goal of this paper is to find the best model for forecasting temperatures, a case study in Java Island. Java Island is the most densely island and the central economy and business in Indonesia. Climate change research in Java Island is important for sustainability. It runs several algorithms i.e., Gradient Boosting, AdaBoost, XGBoost, CatBoost, Light GBM, Random Forest, Support Vector Regression, Extreme Learning Machine, Long Short-Term Memory, Gated Recurrent Unit, Bidirectional Long Short-Term Memory, and Bidirectional Gated Recurrent Unit. The experiment uses a historical daily time series of temperatures from 1 January 1990 to 31 December 2024. In general, the experimental results show that Gradient Boosting produces the highest average coefficient of determination R2 scores of 0.34 and the lowest Mean Absolute Error scores of 0.69. Long Short-Term Memory and Gated Recurrent Units are the deep learning models that also work well for forecasting. According to the experimental results, in some cases, machine learning models outperform deep learning models and vice versa.

Abstract

This study explores the implementation of character education based on core values as the foundation for school culture development at SD Nasima Semarang. Using a qualitative phenomenological approach, data were collected through in-depth interviews, participant observation, and document analysis involving principals, teachers, students, and parents. The implementation of the school’s core values—strong integrity, readiness to take responsibility, empathy, confidence in striving for the best, and communicative courtesy—has been systematically internalized through daily routines, teacher role modeling, and school regulations to cultivate a culture characterized by moral integrity, religious values, and global competitiveness. Effective school management supported by collaborative leadership and parental engagement sustains this culture, while continuous character reinforcement programs address challenges such as inconsistent teacher modeling and digital influence. The study concludes that SD Nasima has developed a living value system that harmonizes Islamic spirituality, Pancasila values, and global citizenship competencies, offering a replicable model for elementary schools in Indonesia

Abstract

This study aims to analyze the culture values contained in the earth alms tradition in Tegowanu Village, Tegowany District, Grobogan Regency. This research uses a descriptive qualitative method, employing data collection techniques such as interviews and library research (i.e. reading and taking notes from books or journals). Tegowanu has a sedekah bumi tradition that is held once a year in the “Bulan Apit” (in the Javanese calendar) and the month of Dzulqo’dah (in the Hijri calendar). The execution of this sedekah bumi tradition consists of: bathing (penjamasan) sacred heirloom objects, ambengan (communal meal), and a shadow puppetry performance. The findings showa that the sedekah bumi tradition actually holds deeply embedded cultural values, such as: local wisdom, mutual cooperation (gotong royong), tolerance, togetherness among residents, and social care.

Abstract

This study aims to develop interactive multimedia learning materials on the solar system to improve elementary school students' understanding of science concepts and independent learning. The research was motivated by the suboptimal use of technology-based learning facilities due to teachers' limited abilities, resulting in conventional, teacher-centered learning that has an impact on students' low conceptual understanding and learning independence. The research method used was the ADDIE Research and Development (R&D) model, which includes the stages of analysis, design, development, implementation, and evaluation. The research subjects consisted of sixth-grade elementary school teachers and students divided into experimental and control classes. Data were collected through concept comprehension tests and self-assessment scales of learning independence using pre-tests and post-tests, then analyzed using N-Gain, independent t-tests, paired t-tests, and MANOVA. The results showed that the N-Gain value for concept understanding in the experimental class was 0.5523 and for learning independence was 0.451, both of which were in the moderate category and higher than the control class, which was in the low category. The independent t-test results show a significant post-test difference between the experimental and control classes in concept comprehension and learning independence. The paired t-test results show a significant increase from the pre-test to the post-test in the experimental class in science concept comprehension and learning independence compared to the control class. The MANOVA test results show that interactive learning multimedia has a significant simultaneous effect on students' understanding of science concepts and learning independence (Sig. = 0.000). Thus, interactive learning multimedia on the solar system material is proven to be effective in improving elementary school students' understanding of concepts and learning independence.
