Abstract

Graph is a discrete mathematical representation widely used to model connectivity in various fields. This study discusses the application of Hamiltonian concepts on the complete bipartite graph K_8^2 as a model for vaccine service route planning at the local level (district). The graph K_8^2 represents eight health facilities in a region, where each facility consists of seven service locations and one other supporting facility. The research method includes constructing a complete bipartite graph, identifying vertices and circuits, and tracing Hamiltonian paths to visualize routes that connect each vertex once in a closed journey. The results show that the K_8^2 graph is effective for designing vaccine distribution routes that systematically and efficiently connect all facilities across eight districts. The complete bipartite graph with Hamiltonian properties proves applicable as a model for public service route planning, with potential implementation in optimizing health logistics distribution, facility inspection, and emergency response for vaccination services at the local level.

Abstract

The problem addressed in this study stems from the low level of scientific literacy among elementary school students and the suboptimal implementation of Education for Sustainable Development (ESD), which has not been well integrated with local wisdom. In addition, Sundanese gastronomic knowledge is increasingly being eroded by modernization, highlighting the need for innovative, contextual, and meaningful learning media. This study aims to analyze the need for developing a learning medium in the form of a storybook based on Ethno-ESD Sundanese gastronomy as a foundation for strengthening students’ scientific literacy. This study employed a quantitative descriptive method within the Design Based Research (DBR) framework at the needs analysis stage. The sample consisted of fifth-grade elementary school students selected through purposive sampling. Data were collected using a Likert-scale questionnaire covering five aspects: prior learning understanding, learning media needs, scientific literacy, integration of Ethno-ESD, and students’ interest in storybooks. Data were analyzed using descriptive statistics in the form of mean scores. The results indicate that students’ need for developing an Ethno-ESD-based storybook is high, with an average score of 4.13. All aspects fall into high to very high categories, with the highest score in the integration of Ethno-ESD Sundanese gastronomy. These findings suggest that students require contextual and engaging learning media that integrate scientific literacy with daily life and local cultural values. Therefore, the development of an Ethno-ESD-based Sundanese gastronomy storybook has strong potential as an innovative solution to enhance elementary students’ scientific literacy.

Abstract

This study aims to analyze the process of developing creative thinking skills in children within the context of early childhood education. This issue is important because creativity is one of the 21st-century competencies that supports problem-solving, innovation, and social adaptation abilities, yet in practice, learning is still often oriented towards academic outcomes and uniform activities. The study uses a qualitative approach with a case study design to obtain an in-depth understanding of the dynamics of children's creativity development in the natural context of learning. The research was conducted at an early childhood education institution in Mataram City, West Nusa Tenggara, involving 12 participants consisting of 6 children aged 5–6 years, 3 teachers, and 3 parents selected through purposive sampling techniques. Data collection was carried out through semi-structured interviews, participatory observation, and documentation, meanwhile, the validity of the data was maintained through source triangulation, method triangulation, member checking, and audit trail. Data analysis used the interactive model of Miles and Huberman, which includes data reduction, data presentation, and drawing conclusions. The results of the study showed three main themes, namely the importance of free exploration space in learning, the role of teachers as facilitators of creativity through scaffolding and open-ended questions, and family support in providing exploratory stimulation at home. These findings indicate that the development of children's creative thinking skills is influenced by the interaction between the learning environment, pedagogical practices, and family support. This study contributes to strengthening the perspective of social constructivism and divergent thinking in understanding children's creativity, as well as providing practical implications for the development of more exploratory, flexible, and process-oriented learning.

Abstract

The background of this study is the growing need for innovative learning media in elementary schools to support students’ understanding of IPAS concepts in a more concrete and meaningful way in line with the advancement of educational technology. This study aims to systematically review the implementation of Augmented Reality (AR) in improving IPAS learning outcomes at the elementary school level through a Literature Review approach. The research method employed was a library research method by analyzing national and international journal articles, conference proceedings, academic books, and relevant research reports. The literature search was conducted through Google Scholar and several academic databases using the keywords “Augmented Reality,” “IPAS learning outcomes,” “IPAS learning,” and “elementary school.” Based on the inclusion criteria, 22 selected articles were analyzed using content analysis techniques. The findings indicate that the use of AR consistently has a positive impact on improving elementary school students’ IPAS learning outcomes, including cognitive aspects (conceptual understanding and material retention), affective aspects (learning motivation and interest), and psychomotor aspects (skills in manipulating and observing virtual objects). These results confirm that AR is an innovative learning medium that supports interactive and contextual learning aligned with the characteristics of 21st-century education. However, the effectiveness of AR implementation depends greatly on teachers’ readiness, the availability of facilities, and school infrastructure support. Therefore, systematic instructional planning, teacher training, and adequate technological resources are essential to optimize the use of AR in improving IPAS learning outcomes in elementary schools.
