Abstract

This research aims to develop a science learning module that is valid, practical, and effective by integrating the Ethno-STEM approach with Acehnese local wisdom, specifically the Rapai Geleng dance. The developed module is intended for junior high school students and focuses on the science topics of vibration, sound, and waves, which are closely related to the rhythmic movements and musical elements of the Rapai Geleng tradition. By embedding local cultural contexts into science learning, the module is designed to provide meaningful and contextual learning experiences for students.This study employed a modified 4D development model consisting of three stages: define, design, and develop. The define stage involved analyzing learning needs, student characteristics, curriculum requirements, learning materials, and learning objectives relevant to Ethno-STEM integration. The design stage focused on structuring the module content, selecting appropriate illustrations and cultural representations, and preparing research instruments, including validation sheets, student response questionnaires, and learning outcome tests. The develop stage involved expert validation, revision based on validators’ feedback, and field testing of the module.The developed module was evaluated through a small-group trial involving 10 seventh-grade students, followed by a class-level trial with 25 seventh-grade students at SMPN 3 Sakti. Data were analyzed using descriptive analysis techniques. Module validity and practicality were determined using percentage calculations, while effectiveness was measured through N-gain analysis based on students’ pretest and posttest results. The findings indicate that the Ethno-STEM-based science learning module achieved a validity score of 81.76%, a practicality score of 92.86%, and an N-gain score of 0.83, which falls into the high category. These results demonstrate that the developed module meets the criteria of being valid, practical, and effective for use in junior high school science learning. The integration of the Rapai Geleng dance into Ethno-STEM learning is therefore recommended as an alternative approach to strengthening culture-based science education and enriching contextual learning resources

Abstract

Hypertension is an increasing global health concern and a leading cause of cardiovascular diseases, including stroke and heart attack. In Indonesia, the prevalence of hypertension continues to rise each year, including in the service area of Puskesmas Perumnas, Kendari City. This study aims to examine the factors associated with hypertension in individuals aged 20–59 years, specifically from the perspectives of nutritional status, physical activity, family history of hypertension, and dietary patterns. This research is an analytical observational study using a case-control design. It was conducted from February to March 2025 in the service area of Puskesmas Perumnas. A total of 98 participants were involved, consisting of 49 hypertensive individuals (cases) and 49 non-hypertensive individuals (controls), selected using purposive sampling. Data was collected through questionnaires and direct measurements, then analyzed using odds ratio and chi-square tests. Cases and controls in this study were comparable in age and gender. Variables that showed a significant association and were proven to be risk factors for hypertension were overweight status (OR = 2.73; 95% CI = 1.20–6.18; p = 0.03), family history of hypertension (OR = 2.72; 95% CI = 1.20–6.16; p = 0.03), and adequate/unhealthy dietary patterns (OR = 6.28; 95% CI = 2.61–15.11; p = 0.00). These three variables contributed to a significant increase in the risk of hypertension. In contrast, light physical activity (OR = 1.51; 95% CI = 0.68–3.36; p = 0.42) did not show a significant association with hypertension and was therefore not considered a risk factor in this study. Overnutrition, a family history of hypertension, and an adequate/unhealthy diet are significant risk factors for hypertension in adulthood, while light physical activity has not been shown to be a significant risk factor. Hypertension prevention efforts should focus on weight control, dietary modification, and screening for individuals with a family history of hypertension.

Abstract

Character education is a strategic agenda in Indonesia’s national education system; however, its implementation in elementary schools still faces various challenges. Previous studies have mostly highlighted implementation aspects, while teachers’ misconceptions about character education have not been systematically examined. This study aims to identify the types of misconceptions elementary school teachers hold regarding character education, the factors causing them, and strategies for improvement. The research design employed an explanatory sequential mixed methods approach involving 150 elementary school teachers in Tasikmalaya Regency. Research instruments consisted of a 25-item Likert questionnaire with Cronbach’s Alpha reliability test, complemented by semi-structured interviews. Findings show that 57% of teachers fall into the medium misconception category, 30% high, and 13% low. The main misconceptions are perceiving character education as identical to enforcing discipline, memorizing moral values, and being the sole responsibility of families. The dominant causal factors are the lack of formal training and the dominance of hidden curriculum. These findings emphasize the importance of sustainable teacher capacity-building programs, integrating character values into lesson plans, and school supervision. The limitation of this study lies in its regional scope and focus on teachers’ perspectives, suggesting that future studies should involve students and parents.

Abstract

Science is a fundamental discipline that aims not only to transfer factual knowledge but also to develop critical, logical, and analytical thinking skills in students. This study aims to analyze the effect of the Probalusan learning model (Problem-Based Learning and Susan Loucks Horsley based on problem solving, discussion, and collaboration) on the attitudes and learning outcomes of eighth-grade students of SMP Negeri 6 Sentani. The Probalusan model was chosen because it has the potential to increase active student participation, foster curiosity, and facilitate the understanding of science concepts through solving real problems. This study uses a quantitative approach with a quasi-experimental design, namely a pretest-posttest control group design. The study population was all eighth-grade students, with two classes selected as samples: one experimental class using the Probalusan model, and one control class using conventional methods. The instruments used included a learning attitude questionnaire and a science learning outcome test. Data analysis was carried out using statistical tests, namely normality, homogeneity, t-test, and N-Gain tests. The results of the t-test on the posttest data showed a significant difference between the control class and the experimental class. The results showed that science learning using the Probalusan model can improve students' attitudes and learning outcomes.

Abstract

This study aims to analyze the sustainability of Lembah Palu variety shallot farming in Sigi Regency from economic, social, and environmental perspectives. The research involved 50 shallot farmers selected using a proportional random sampling technique. Primary data were obtained through interviews, field observations, and questionnaires, supported by secondary data from relevant institutions. The sustainability level was assessed using the Multi-Dimensional Scaling (Rapfish) approach to generate sustainability indices for each dimension. The results showed that the overall sustainability status of shallot farming was categorized as less sustainable, with an average index value of 49.37. The environmental dimension recorded the lowest index value (26.97), indicating high vulnerability due to pest and disease intensity, erosion risk, and low utilization of organic inputs. The economic dimension was categorized as fairly sustainable (64.00), as farming activities still provided financial benefits despite high production costs and limited capital access. Meanwhile, the social dimension was also fairly sustainable (57.13), reflecting contributions to household welfare, although farmer institutional strength and land tenure certainty require improvement. Strengthening environmentally friendly practices, improving cost efficiency, and empowering farmer institutions are essential to support balanced and sustainable shallot agribusiness development

Abstract

Rono Dange is a traditional smoked anchovy product that has great economic value and potential as a local food. However, there are differences in quality, especially in terms of microbiology and food safety. This study aims to identify the dominant bacteria found in Rono Dange products and evaluate heavy metal contamination of lead (Pb), cadmium (Cd), and magnesium (Mg) as indicators of consumption safety. Rono Dange samples were obtained from five traditional processors in Lero Village and analyzed in the laboratory. Bacterial isolation and identification were performed using pure culture techniques, DNA extraction, 16S rRNA gene amplification using PCR, and DNA sequence analysis to determine the dominant species. Heavy metal content testing was performed using the AAS (Atomic Absorption Spectrophotometry) method in accordance with the SNI 7387:2009 standard. The results showed that the dominant bacteria found in the Rono Dange samples belonged to the genera Bacillus, Staphylococcus, and Pseudomonas, which play a role in the formation of the distinctive aroma but also indicate potential contamination if not properly controlled. The concentrations of Pb and Cd heavy metals in most samples were still below the SNI threshold, while Mg levels showed variations influenced by fuel and smoking duration. Overall, it was concluded that Rono Dange is still suitable for consumption, but it is necessary to standardize the smoking process and control the cleanliness of the production environment to ensure product quality and safety.

Abstract

Microplastic and nanoplastic pollution has emerged as a major environmental and public health issue, particularly in developing countries such as Indonesia, where contamination levels are among the highest in the world. Recent findings from Ekspedisi Sungai Nusantara (2022) revealed microplastic concentrations of up to 636 particles per liter in East Java’s rivers, indicating widespread exposure through water, air, and food sources. Indonesia also ranks third globally in plastic pollution, contributing approximately 3.4 million tons annually. This study employs a literature review and policy analysis approach to assess the impact of microplastic exposure on maternal and fetal health, with an emphasis on preterm birth risk and the adequacy of current regulatory frameworks. Evidence from human and animal studies indicates that microplastics can translocate across the placental barrier, inducing oxidative stress, inflammation, and endocrine disruption that may impair fetal development and increase the risk of preterm birth. Despite the implementation of the Regulation of the Minister of Health of the Republic of Indonesia No. 2 of 2025 concerning reproductive health, the absence of explicit environmental pollutant protection clauses highlights a critical policy gap. Strengthening intersectoral collaboration among the Ministry of Environment, the Ministry of Health, and the Ministry of Marine Affairs and Fisheries is essential to establish national safety thresholds, implement continuous monitoring, and integrate reproductive health protections into environmental policies. This study underscores the urgent need for comprehensive microplastic management strategies and maternal health safeguards to mitigate the growing risks associated with microplastic and nanoplastic exposure in Indonesia.

Abstract

Stunting remains a major nutritional problem in Indonesia, particularly in vulnerable regions such as South Buru Regency, Maluku Province. Local food diversification represents a strategic approach to improving community nutrition and food security. This study evaluated the nutritional value and socio-ecological potential of Hotong (Setaria italica), a traditional cereal cultivated by local communities in Namrole District and adapted to dryland farming systems. A quantitative descriptive method was applied through a survey of 70 Hotong-farming households in Waenewen Hamlet, Labuang Village, Namrole District, Buru Regency, combined with proximate analysis of Hotong grains based on AOAC standards. The results showed that Hotong contains ash (1.33%), protein (11.60%), fat (3.43%), crude fiber (2.20%), and carbohydrates (65.31%). This nutritional composition indicates that Hotong can contribute up to 40% of protein requirements and approximately 35% of daily iron needs for toddlers aged 1–3 years. Furthermore, 86.67% of farmers reported annual production of ≥ 4 quintals despite relying on traditional cultivation practices, highlighting the crop’s availability and sustainability. These findings demonstrate that Hotong has significant potential as a functional local food for stunting prevention, while also reflecting cultural resilience and local wisdom in maintaining food systems under dryland conditions. Integrating Hotong into regional nutrition and food security programs, including the development of locally processed food products, may contribute to improving the nutritional status of toddlers in dryland areas.

Abstract

Problems in developing the coconut-based creative industry in North Sulawesi Province include limited business capital and modern processing technology, inconsistent product quality, and weak promotion and marketing. As a result, the Micro, Small, and Medium Enterprises (MSMEs) sector is unable to maximize the potential of coconuts as a significant source of added value. This study aims to examine the added value of coconut-based food products and formulate policy strategies for the development of coconut-based creative industries MSME level. The research method is added value analysis using the Hayami (1987) approach and SWOT analysis (Strengths, Weaknesses, Opportunities, Threats) for policy strategy formulation. The results of the study show that the output value of coconut-based food products reaches IDR 250,000 per unit, with an added value of IDR 25,214 per product and an added value ratio of 71%. Labor compensation is recorded at IDR 3,044 per kilogram or 12% of the added value, while the profit obtained is IDR 22,170 per product or 88%. SWOT analysis recommends a development strategy oriented towards a combination of S-O (Strengths–Opportunities) and W-O (Weaknesses–Opportunities), through improving production capacity and quality, strengthening promotion, and building partnerships with stakeholders, facilitated by the local government
