This study aims to develop a Student Worksheet (Lembar Kerja Peserta Didik [LKPD]) based on the local wisdom of Besilek Serawai for sixth-grade elementary science education and to evaluate its validity. The study employed the ADDIE development model, consisting of five stages: Analyze, Design, Develop, Implement, and Evaluate. The developed LKPD integrates Besilek Serawai, a traditional martial art of the Seluma community, with the concept of the human locomotor system in science instruction. The worksheet was validated by two subject-matter experts and two media experts. Material validation yielded an average score of 4.26, equivalent to a validity percentage of 85.2%, while media validation produced an average score of 4.42, equivalent to a validity percentage of 88.4%. Both results were categorized as highly valid. The LKPD incorporates contextual learning activities that connect scientific concepts with local cultural practices, thereby enhancing the meaningfulness and relevance of learning to students’ everyday lives. These findings indicate that the developed LKPD is highly valid and suitable for use in elementary science learning. This study contributes to the development of culturally responsive instructional materials and supports the implementation of the Merdeka Curriculum in elementary education.
Learning mathematics in the 21st century requires developing critical thinking skills. However, traditional methods still dominate the classroom, such as using textbooks as learning resources and whiteboards as learning media, making it difficult for students to understand triangle congruence visually and dynamically. This research aims to develop animated video media using GeoGebra and Artificial Intelligence (AI) on triangle congruence material for grade IX junior high school students and to describe their validity and practicality. The research uses the Research and Development (R&D) method with the ADDIE model, which includes the stages of analysis, design, development, implementation, and evaluation. The test subjects were 14 grade IX students and 1 mathematics teacher, with validation sheet instruments and practicality questionnaires. The results showed that the average validity of the media was 90% with the very valid category, while the practicality reached 89.11% with the very practical category. These findings show that GeoGebra and AI-assisted animation videos are feasible alternatives to modern, interactive mathematics learning media that facilitate students’ critical thinking skills in triangle congruence materials.
Stunting remains a serious problem in human development as it affects children’s growth and development and has long-term implications for the quality of human resources. Various efforts to address stunting have generally emphasized health interventions and the dissemination of nutritional information; however, these approaches often overlook family dynamics as the main arena for parenting decision-making. This study aims to analyze how nutrition knowledge is negotiated in parenting practices among rural families with stunting cases in Kepahiang Regency. This study employs a qualitative approach with a case study design. The informants consisted of 16 participants, including mothers of stunted children under five, husbands, children who are able to communicate their preferences, and supporting local actors such as village midwives, members of the Stunting Task Force, and village officials. Data were collected through in-depth interviews and observations and analyzed using thematic analysis. The findings show that nutrition knowledge within families is derived from multiple sources and is not applied linearly, but is continuously renegotiated in accordance with socio-economic conditions, family relations, and everyday parenting practices. Parenting practices are shaped through a negotiation process involving mothers, other family members, and interactions with local institutional actors. This study contributes to the literature by conceptualizing nutrition knowledge as a negotiated social process embedded in rural family dynamics. It concludes that stunting prevention efforts need to position families as active subjects, with approaches that are sensitive to social, economic, and cultural contexts in rural settings.
Ulu script, the indigenous writing system of the Rejang people, is taught as part of the Bareang local-content subject in Kepahiang Regency, Bengkulu, yet its instruction at SD Negeri 13 Kepahiang remained lecture-based and reliant on a limited stock of shared textbooks, leaving 60% of fourth-grade students below the minimum attainment criterion and their learning motivation low. This study aimed to develop interactive multimedia for Ulu script that is valid and practical and can facilitate the learning motivation of fourth-grade students. The research used a research and development design following the 4D model of define, design, develop, and disseminate, limited in practice to the develop stage. The product was built with Google Apps Script and Google Sheets and delivered as a web application containing material menus and a group game. Participants were 31 fourth-grade students, comprising five in the limited trial and twenty-six in the field trial, together with two expert validators and the class teacher. Data were collected through interviews, questionnaires, and documentation, and analysed descriptively as percentages. Content-expert validation reached 90% and media-expert validation 88.6%, both highly valid. Student responses reached 85.4% in the limited trial and 84.02% in the field trial, and teacher responses 89.66% and 86.6%, all highly practical. Learning motivation among the twenty-six students reached 87.9%, categorised as very high. The developed multimedia is therefore valid and practical and is able to facilitate students' learning motivation
This study aim was to determine the relationship between stress levels and the incidence of primary dysmenorrhea in tenth-grade female high school students. The research method used an observational analytic approach with a cross-sectional approach. A sample of 129 female students was drawn using a total sampling technique. The results showed that 50 (38.8%) female students had severe stress levels, 30 (23.3%) had mild stress, and 96 (74.4%) had primary dysmenorrhea. Bivariate analysis showed a significant relationship between stress levels and primary dysmenorrhea (p-value = 0.001). In conclusion, the majority of tenth-grade female students at SMA Negeri 4 Bengkulu City in 2013 had severe stress levels (38.8%), and the majority experienced primary dysmenorrhea (74.4%). The results of the bivariate analysis using the Chi-Square test showed a significant relationship between stress levels and the incidence of primary dysmenorrhea, with a p value of 0.001 (p < 0.05). This finding indicates that the higher the stress levels experienced by adolescent girls, the greater the likelihood of primary dysmenorrhea. The results of this study emphasize the importance of promotive and preventive efforts through reproductive health education and stress management in adolescents to reduce the incidence of primary dysmenorrhea.
