Abstract

To keep pace with the Industrial Revolution 4.0, students require teacher guidance to maintain a foundation rooted in local wisdom. This can be achieved through various approaches, such as SETS-based (Science, Environment, Technology, and Society) science instruction integrated with local wisdom and microlearning. Local wisdom serves as a means to balance the rapid advancement of science and technology. This study aims to analyze the implementation of SETS-based science instruction—integrated with local wisdom and microlearning—in junior high schools (SMP and MTs) in Merauke. A descriptive qualitative research method was employed, utilizing a questionnaire comprising 16 statements. The study involved 23 science teachers from SMP and MTs schools in Merauke. Data analysis using descriptive statistics revealed that 76% of respondents had never implemented SETS-based science instruction integrated with local wisdom, 68% did not understand the concept of microlearning, and 89% expressed interest in implementing SETS-based science instruction that integrates local wisdom and microlearning. Respondents also outlined plans to implement science instruction that combines technology, local wisdom, and interactive learning methods.

Abstract

“Human factors such as knowledge, work fatigue, attitudes, and manual material handling practices are considered important determinants of occupational accidents among loading and unloading workers. This study aimed to determine the relationship between human factors and occupational accidents among loading and unloading workers at Balohan Port, Sabang. This study used a quantitative design with a cross-sectional approach. The population consisted of all freelance loading and unloading workers at Balohan Port, with a total sample of 37 respondents selected using the total population technique. Data were collected through interviews using standardized questionnaires and analyzed using Fisher’s Exact Test. The results showed that most respondents had good knowledge (75.7%), moderate work fatigue (73%), positive attitudes toward occupational safety (73%), and fairly good manual material handling practices (67.6%). Occupational accidents were still relatively high at 59.5%. Bivariate analysis showed a significant relationship between work fatigue (p-value =0.028) and attitude (p-value =0.028) with occupational accidents. Meanwhile, knowledge (p-value =0.056) and manual material handling (p-value =0.073) were not significantly associated with occupational accidents. The study concludes that work fatigue and worker attitudes are dominant factors related to occupational accidents among loading and unloading workers at Balohan Port.

Abstract

Burasse leaves (BL) are utilized by the community of Enrekang Regency as both a traditional fever remedy and a food source. This study aimed to determine the physical pharmacognostic characteristics and non-specific parameters of Burasse leaf extract from Enrekang (BLEE) as a raw material for natural medicine (RMNM). This experimental research involved preparing dried powder leaves, macerating it with 70% ethanol, and evaluating its physical pharmacognostic characteristics (PPC). The PPC evaluation included macroscopic and organoleptic identification of both the simplisia and the extract, alongside non-specific parameter (NSP) assays for moisture content (MC), total ash content (TAC), and acid-insoluble ash content (AIAC). Results showed that the dried simplisia leaves were triangular or ovate-lanceolate, 7–15 cm long, 5–9 cm wide, with entire margins, brownish-green color, and were odorless and tasteless. The extract was thick and viscous, blackish-brown, odorless, and tasteless. The NSP values were: MC = 2.183 ± 0.002%, TAC = 6.475 ± 0.001%, and AIAC = 1.065 ± 3.511%. In conclusion, these findings can serve as a quality standard reference for BLEE in developing natural medicine formulations.

Abstract

This study aims to analyze the effect of adding camphor or naphthalene to gasoline on the performance and exhaust emissions of a gasoline engine. An experimental method was applied using a single-cylinder, four-stroke Enduro XL gasoline engine with camphor concentrations of 0%, 5%, 10%, 20%, and 30%. Tests were conducted at engine speeds of 1,200, 1,400, 1,600, 1,800, and 2,000 rpm. The parameters analyzed included calorific value, fuel density, effective shaft power, fuel consumption, thermal efficiency, exhaust gas temperature, and carbon monoxide emissions. The results showed that increasing the camphor concentration reduced the fuel calorific value from 12,347 kcal/kg to 6,306 kcal/kg and increased the density from 750 kg/m³ to 780 kg/m³. The addition of camphor tended to increase effective shaft power and reduce measured fuel consumption. However, carbon monoxide emissions increased significantly, particularly at camphor concentrations of 20–30% and at low engine speeds. At 1,200 rpm, CO emissions increased from 0.7% for pure gasoline to 8.7% for the 30% camphor mixture. Therefore, camphor addition creates a trade-off between improved engine performance and deteriorating exhaust emission quality. High camphor concentrations are not recommended, while concentrations of 5–10% require further testing to assess their technical effectiveness, environmental impact, and long-term effects on engine components.

Abstract

The rapid adoption of electric vehicles (EVs) presents significant challenges in charging infrastructure planning, particularly for diverse vehicle fleets in developing regions. This study proposes an expert system-based decision support framework for EV charging infrastructure planning, specifically addressing two-wheeler and bus fleet scenarios. The framework integrates scenario-based demand characterization with rule-based inference to provide location recommendations and capacity planning decisions. Using data from Indonesian urban transportation contexts, the expert system evaluates multiple criteria including demand patterns, infrastructure availability, and energy consumption profiles. Results indicate that the proposed framework successfully identifies optimal charging locations with 87.5% accuracy compared to expert validation, while reducing planning time by approximately 40% compared to conventional methods. The system provides decision-makers with actionable recommendations for prioritizing infrastructure investments across different fleet types. This research contributes to the growing body of knowledge on AI-based decision support systems for sustainable transportation infrastructure, with implications for policy formulation and urban planning in developing economies.

Abstract

Cognitive function decline in older adults is one of the health problems that can affect quality of life, psychological well-being, and social functioning. This condition is often accompanied by anxiety, depression, and social isolation, thus requiring effective interventions to support the mental and cognitive health of the elderly. One of the non-pharmacological approaches that has been widely developed is mindfulness, which is the practice of full awareness of present experiences with an open and non-judgmental attitude. This study aims to explore the effectiveness of mindfulness-based interventions in overcoming cognitive function decline in older adults. The research method used was a literature review by examining various articles and studies related to the effectiveness of mindfulness in the elderly. The research process was conducted through the collection, analysis, and synthesis of data from various relevant scientific sources. The results of the review showed that mindfulness-based interventions had a positive impact on cognitive function and mental health in older adults. Most studies demonstrated improvements in cognitive function, reductions in anxiety and depression symptoms, and enhanced psychological well-being among older adults participating in mindfulness programs. Therefore, mindfulness has been proven effective as an intervention to help improve cognitive function and quality of life in older adults.

Abstract

Adolescents continue to experience various nutritional problems, one of which is the increasing prevalence of overweight and obesity. The 2023 Indonesian Health Survey (SKI) reported that the prevalence of overweight and obesity among Indonesian adolescents aged 16–18 years was 8.8% and 3.3%, respectively. In Central Java, fruit and vegetable consumption among adolescents aged 15–19 years remained limited, with 68.1% consuming only 1–2 servings per day. This study was conducted at SMA Batik 1 Surakarta. The study aimed to examine the association between fruit and vegetable consumption and nutritional status among adolescents using an analytic observational design with a cross-sectional approach. A total of 76 students were selected through purposive sampling. Fruit and vegetable consumption was assessed using an FFQ, nutritional status was determined based on BMI-for-age (BMI/A), and data were analyzed using the Chi-Square test. The proportions of infrequent and frequent consumption were both 50.0%, while 73.7% of students had normal nutritional status and 26.3% had abnormal nutritional status. The p-value of 0.602 indicated no significant association between fruit and vegetable consumption and nutritional status. Nutritional status may be influenced by various factors, including dietary adequacy, eating patterns, physical activity, genetic factors, and the social environment.

Abstract

Celiac disease is an autoimmune disorder requiring a gluten-free diet; therefore, optimizing this diet involves the role of specific fibers in the foods consumed. This study aimed to analyze the levels of soluble fiber, insoluble fiber, and total dietary fiber in cookies made from varying formulations of dried cassava flour (gaplek flour) and tempeh flour. An experimental design using a Completely Randomized Design (CRD) was employed, comprising four formulations based on the ratio of dried cassava flour to tempeh flour: F1 (0% and 0%), F2 (25% and 75%), F3 (50% and 50%), and F4 (75% and 25%), with two replications and duplicate sample analyses. Fiber content was analyzed using the enzymatic-gravimetric method based on AOAC Official Method 991.43 (1992). Data were analyzed using the Kruskal-Wallis test and Dunn-Bonferroni post-hoc test at a 95% significance level. The results showed that formulation variations significantly affected the levels of soluble fiber, insoluble fiber, and total dietary fiber (p = 0.03). Formulation F3 yielded the highest levels—0.85 ± 0.45%, 10.34 ± 0.14%, and 11.20 ± 0.18%, respectively—while the lowest levels were found in F1 (0.43 ± 0.01%, 6.18 ± 0.18%, and 6.62 ± 0.19%). Post-hoc testing revealed significant differences between F1 and F3. Cookies with the F3 formulation exhibited the highest fiber content, indicating potential for development as a gluten-free food alternative that supports fiber intake for individuals with celiac disease. Further research is recommended to assess gluten-free safety, nutritional quality, and product acceptability.
