Emotional health and spiritual well-being in trauma survivors of natural disasters in Palu, Central Sulawesi, Indonesia: The role of community resilience
Get PDFNatural disasters struck Palu, Indonesia, on September 28, 2018. Nevertheless, the problem of post-traumatic stress disorder (PTSD) symptoms remains, even though the Palu community builds resilience communally concerning emotional and spiritual conditions. This research aims to investigate the relevance of community resilience to emotional health and spiritual well-being in trauma survivors of natural disasters in Palu. The qualitative research method involved a photovoice approach involving voices from photographs. The seven participants were all residents of Palu and came from areas that had experienced the greatest impact of natural disasters. Data analysis in the research was based on thematic analysis. The research findings are that community resilience is related to emotional health and spiritual well-being based on eight factors: themes related to emotional health are residential, financial, cultural, and capital; while those related to spiritual well-being are supernatural, ritual, social, and moral. The eight factors emphasize interconnected meanings and describe a model of community resilience. The research contributes to the significance of new insights that motivate governments, social institutions, and policymakers in terms of human empowerment, social advocacy, and sustainable development
Physical, Chemical, and Organoleptic Characteristics of Tempeh Cookies
Get PDFCookies are widely consumed snack options made primarily from wheat flour. Alternative materials, such as tempeh flour, are needed to replace wheat flour in the production of cookies. Tempeh contains high levels of protein and crude fiber. This research aims to determine the effect of wheat flour and tempeh flour formulations on the physical, chemical, and organoleptic characteristics of cookies. This research employed a one-factor Completely Randomized Design (CRD), with variations in wheat flour and tempeh flour (F1, 100% wheat flour: 0% tempeh flour), (F2, 75%: 25%), (F3, 50%: 50%), and (F4, 25%: 75%). A total of 31 untrained panelists carried out organoleptic evaluations on the product. The analyzed physical and chemical properties include moisture content, ash, protein, fat, carbohydrates, crude fiber, and texture. Organoleptic tests include taste, color, aroma, hardness, crispness, aftertaste, and overall impression. Data analysis was performed using One-way ANOVA at a 5% significance level, followed by Duncan's post-hoc test. Results indicate that the different formulations of wheat flour and tempeh flour significantly affect the moisture content, fat, protein, carbohydrates, crude fiber, hardness, crispness, and organoleptic properties of cookies. The best cookie formulation was obtained at F4 (25% wheat flour: 75% tempeh flour), with the highest protein and crude fiber content of 16.10% and 12.36%, respectively. This finding had implications for reducing dependence on imported wheat flour and encouraged the diversification of local food products based on fermented soybeans with high protein and fiber content
AN OVERVIEW OF ADVANCED 2,2-Diphenyl-1-picrylhydrazyl (DPPH) ANALYSIS TECHNIQUES
Get PDFAntioxidants play a crucial role in preventing oxidative damage, necessitating reliable analytical techniques for their evaluation. Oxidative stress, resulting from an imbalance between free radicals and antioxidants in the body, has been associated with various chronic diseases, including cancer, cardiovascular disorders, and neurodegenerative conditions. Therefore, accurately assessing antioxidant activity is essential for developing health-related products and validating their efficacy. This study reviewed and compared various analytical methods used to determine antioxidant activity, emphasizing their advantages, limitations, and applicability across different sample types. Traditional spectrophotometric assays, such as the 2,2-diphenyl-1-picrylhydrazyl (DPPH) method, remain widely used because of their simplicity and cost-effectiveness, although they often suffer from matrix interferences. Advanced techniques, including gas chromatography–mass spectrometry (GC–MS), high-performance liquid chromatography coupled with DPPH (HPLCDPPH), electrochemical methods, microfluidic systems, and miniaturized paper-based assays, provide improved sensitivity, accuracy, and efficiency. These methods enable a more comprehensive assessment of antioxidant activity by offering deeper insights into reaction mechanisms and compound interactions. The integration of multiple analytical approaches can further enhance antioxidant characterization, supporting applications in the food, pharmaceutical, and biomedical industries. This review highlights the importance of selecting appropriate analytical techniques based on research objectives and sample characteristics, while also outlining future directions for advancing antioxidant detection methodologies

Investigation of The Effects of Carbon Dioxide from Paper Combustion on Temperature Changes
Get PDFThis study explores the relationship between carbon dioxide (CO₂) concentration from paper combustion and temperature changes using a greenhouse effect simulation. Two desiccators were used: desiccator A with an LED lamp as an additional heat source, and desiccator B without an external heat source. The results showed that an increase in CO₂ in desiccator A significantly raised the temperature, demonstrating CO₂'s role in heat retention. However, in desiccator B, a temperature drop occurred due to the endothermic effects of paper combustion and water evaporation. These findings highlight the importance of external energy sources in manifesting the greenhouse effect and explain the complexity of the thermodynamic processes involved. This study contributes to a deeper understanding of CO₂-induced temperature changes and its relevance to global warming. The experiment can be used as an effective educational tool to introduce students to the greenhouse effect concept

The Relationship between Self-Efficacy and Science Anxiety with Science Literacy Among Senior High School Students in Biology Learning
Get PDFScientific literacy is a crucial competency in the 21st century, particularly in understanding scientific issues, evaluating associated risks and benefits, and making decisions based on scientific reasoning. However, the level of scientific literacy among students in Indonesia, including those at SMAN 6 Semarang, remains relatively low. Two psychological factors suspected to influence this condition are self-efficacy and science anxiety. This study aims to investigate the relationship between self-efficacy, science anxiety, and students’ scientific literacy. The research employed a non-experimental quantitative approach with a correlational design. The sample was selected using purposive sampling. Data were collected through tests and questionnaires: the self-efficacy questionnaire was developed based on indicators by Bosscher and Smit (1998), the science anxiety questionnaire was adapted from the Abbreviated Science Anxiety Scale (ASAS) by Megreya et al. (2021), and the scientific literacy test items were constructed based on the 2025 PISA indicators. Data analysis included Pearson correlation, multiple correlation, and multiple linear regression. The results showed a significant relationship between self-efficacy and scientific literacy (p = 0.027; r = 0.174; contribution = 3%). Science anxiety also showed a significant relationship (p = 0.027; r = 0.173; contribution = 3%). Simultaneously, both variables significantly correlated with scientific literacy (p = 0.001; R = 0.281), contributing 6.7%, although the strength of the relationship was weak

ABSTRACT
Marriage is a sacred process and has great significance in human life. Some of them are increasing economic stability through the pooling of resources and income of husband and wife, reducing the rate of promiscuity that damages the future, and marriage data can be used by the government to prepare population policies, demographic structures and regional development planning. However, in the last five years, the trend of decreasing marriage rates in Sokaraja District, Banyumas Regency has been quite significant. Among the factors that affect the decline in the marriage rate are the increase in women's economic independence, the high level of education, the high awareness of the importance of mental and financial readiness before marriage and so on. Therefore, it is important for the government and the KUA of Sokaraja District to understand and determine a policy that supports a balance between economic, social and family development by conducting a forecast. This forecast aims to provide a predictive value of the number of marriages that occur in the coming period. In this study, the Triple Exponential Smoothing method was used with an alpha constant value of 0.1. The forecasting results indicate that the projected number of marriages in 2025 is 374, with a Mean Absolute Percentage Error (MAPE) of 41%, indicating that the forecasting error is relatively high; however, it remains within an acceptable range for describing patterns and trends in changes in marriage rates in future periods
