Based on the 2023 Indonesian Health Survey, the prevalence of overweight among adults reached 23.4% nationally and 24.5% in East Java Province. This condition highlights the need for food innovation, particularly high-fiber snacks suitable for overweight adults. This study aimed to develop cereal based on okara (soy pulp) flour and mung bean flour as an alternative high-fiber food product. Organoleptic testing was conducted on 30 semi-trained panelists evaluating color, aroma, texture, and taste using hedonic and hedonic quality tests. Data were analyzed using the Kruskal–Wallis test followed by the Mann–Whitney test, while nutrient content analysis was analyzed using One Way ANOVA followed by Duncan’s post hoc test. The results showed that in the hedonic test, color, texture, and taste parameters were significantly different (p<0.05), while aroma was not significantly different (p>0.05). In the hedonic quality test, color and taste showed significant differences (p<0.05), whereas aroma and texture did not (p>0.05). Overall, formulation 922 was the most preferred by panelists. The nutritional content of the cereal ranged from 407–410 kcal for energy, 76.44–77.53% carbohydrates, 8.91–9.66% protein, 6.80–7.30% fat, 5.20–5.51% moisture, 1.26–1.41% ash, and 9.72–10.90% total dietary fiber. The developed cereal is classified as a high-fiber food and has potential as a healthy snack for overweight adults.

Health issues among the elderly are often related to declining bodily functions, digestive disorders, and specific nutritional needs for easily digestible foods. The 60-and-older age group is at high risk for gastrointestinal disorders due to low fiber intake. Therefore, alternative foods are needed that are soft in texture, neutral in taste, safe, and nutritious. One potential solution is the development of food products based on tempeh gembus with the addition of banana hearts, which are rich in fiber, soft in texture, and readily available. This study employed an experimental method using a Completely Randomized Design (CRD) to test three formulation variations (F1, F2, F3). The nutritional content of formulation F1 includes energy 111.575 kcal, carbohydrates 20.185 g, protein 6.91 g, fat 0.355 g, and fiber 6.67 g. Formula F2 contains 88.225 kcal of energy, 14.095 g of carbohydrates, 7.72 g of protein, 0.205 g of fat, 7.3 g of fiber, and 0.0015% flavonoids. Formula F3 has 107.015 kcal of energy, 7.995 g of protein, 0.295 g of fat, 6.88 g of fiber, and 0.0021% flavonoids. In conclusion, the best tempeh with added banana hearts is Formula F2, with its nutritional content, fiber, flavonoids, and BAL >10⁸ CFU/g, which has the potential to serve as a functional food and probiotic source to help improve digestive health in the elderly. Further testing is recommended directly on elderly groups, along with product shelf-life testing.

This study aims to analyze the effect of renewable energy, energy consumption, and Gross Domestic Product (GDP) per capita on carbon dioxide (CO2) emissions in Indonesia for the period 1995-2024. This study uses secondary data over time (time series) with the Ordinary Least Square (OLS) multiple linear regression analysis method corrected using the Newey-West Heteroskedasticity and Autocorrelation Consistent (HAC) approach. The results show that renewable energy does not have a significant effect on CO2 emissions, which is caused by the still low share of renewable energy in the national energy mix which only reaches 10.95% in 2024. Energy consumption has a positive and significant effect on CO2 emissions, where every 1% increase in energy consumption increases CO2 emissions by 84.23%. Gross Domestic Product (GDP) per capita has a positive and significant effect on CO2 emissions. Every 1% increase in GDP per capita increases CO2 emissions by 35.03%, indicating that Indonesia remains on the EKC curve. Simultaneously, all three variables have a significant effect, with an adjusted R-squared value of 53.63%. This finding confirms that Indonesia's energy mix, still dominated by fossil fuels, is a major factor in high carbon emissions. Comprehensive energy efficiency policies, accelerated renewable energy transitions, and greener and more sustainable economic growth strategies are needed.

This intervention can be used as a non-pharmacological alternative to support psychological recovery of pre-operative patients.

This study aims to analyze the impact of the geopolitical conflict between the United States, Israel, and Iran in 2026 on global macroeconomic stability and climate change dynamics. Using a qualitative approach through a Systematic Literature Review (SLR), this research synthesizes findings from various international journal articles, reports, and academic sources. The results indicate that the conflict has significantly disrupted global energy markets, leading to a sharp increase in oil and gas prices. This energy shock has triggered global inflationary pressures, reduced purchasing power, and increased economic uncertainty across both developed and developing countries. Furthermore, monetary tightening policies implemented to control inflation have created trade-offs with economic growth, increasing the risk of global recession. On the fiscal side, government interventions such as energy subsidies have helped mitigate short-term impacts but have raised concerns about long-term fiscal sustainability. In addition, the energy crisis has slowed the transition toward renewable energy, thereby exacerbating climate change risks. The study highlights the interconnectedness between geopolitical conflict, macroeconomic instability, and environmental sustainability. Therefore, coordinated global policies and integrated economic strategies are essential to address these multidimensional challenges effectively.

Male masculinity is a common theme in advertising. These potrayals often depict men as hardworking, resilient, and physically strong, thereby shaping an ideal male identity. This study uses Sara Mills’ critical discourse analysis perspective to examine the representation of the 2023 Extra Joss advertisement “Laki Buktikan!”. A qualitative descriptive approach is used, with data in the form of visuals, verbal narratives, and slogans that appear in advertising videos accessed via the TikTok application. The analysis will focus on the subjects and objects in the advertisement, the representation of masculinity, the position of the audience, the narrative structure, and the surrounding social context and gender ideology. The result of study show that the advertisement represents masculinity as an identity that must be continuously proven through strength, physical toughness, endurance, and a never-give-up attitude. Failure, defeat, and adversity are not condition that must be passively accepted, but rather condition demanding an active response from men to take concrete action. The advertisement not only promotes product, but also reproduces the ideology oh hegemonic masculinity by linking male self-proving to consuming Extra Joss energy drinks.

Coffee husk is an agro-industrial waste with significant potential to be utilized as a renewable energy source through the fast pyrolysis process. This study aims to analyze and optimize gas production from the fast pyrolysis of coffee husk biomass using a screw reactor through single-particle-based Computational Fluid Dynamics (CFD) simulations. The simulations were conducted by varying the operating temperature at 500°C, 600°C, and 700°C to examine pressure distribution, heat transfer, particle temperature, and the formation of pyrolysis products, namely bio-oil, biogas, and biochar. The modeling was performed using COMSOL Multiphysics 6.2 with a numerical approach to represent thermal phenomena and biomass decomposition reactions during the pyrolysis process. The simulation results indicate that increasing temperature significantly affects the rate of heat transfer and the temperature distribution of coffee husk particles. At 600°C, heat transfer and temperature distribution are more uniform compared to 500°C, although heating at the particle core is not yet fully optimal. The pressure distribution shows a stable flow of pyrolysis gas from the bottom to the top of the reactor. In terms of products, increasing temperature leads to a reduction in biochar and bio-oil formation due to the occurrence of secondary reactions, while biogas production increases. The highest gas production is achieved at 700°C, indicating the most optimal condition for maximizing gas yield from fast pyrolysis. Therefore, single-particle-based CFD simulation can be used as an effective tool to understand pyrolysis mechanisms and optimize process parameters in a screw reactor.

This study aims to analyze the feasibility of implementing Solar-Powered Street Lighting (PJUTS) as an alternative lighting solution in Campus C of UNINDRA PGRI. The background of this research is driven by the high operational electricity costs of the existing conventional street lighting system and the need to transition toward clean energy. The analysis methods include a technical comparison of off-grid systems, an economic evaluation based on cost savings, and an assessment of environmental impacts. The technical analysis indicates that PJUTS is highly feasible due to its ability to operate independently without reliance on the national electricity grid, thereby ensuring lighting continuity during power outages. From an economic perspective, although the initial investment (CAPEX) is higher than that of conventional street lighting, the project is considered feasible as it eliminates monthly electricity bills permanently, resulting in long-term budget efficiency and financial benefits. The Payback Period analysis shows that the initial investment can be recovered through cumulative operational cost savings. Environmentally, the implementation of PJUTS significantly contributes to carbon emission reduction and supports the Green Campus vision through the utilization of renewable energy. Overall, the transformation of the existing street lighting system into PJUTS represents a strategic and feasible initiative that fulfills effectiveness, efficiency, and sustainability criteria.

The increasing demand for electrical energy each year and the high dependence on fossil energy, which has negative environmental impacts, necessitate the development of alternative renewable energy sources. One potential source that can be utilized is mechanical energy from human activities through the application of piezoelectric technology in paving blocks. In addition, studies on the effect of piezoelectric circuit configurations, particularly comparisons between series and parallel circuits in generating electrical power, are still limited. This study employed an experimental method using a piezoelectric paving block prototype, with testing conducted under a static load of 60 kg. The measured parameters included output voltage and current, which were then used to calculate the generated power. The experimental results show that the parallel circuit configuration produced a higher average electrical power of 1.51 mW compared to the series circuit, which generated an average power of 1.37 mW. The increase in power in the parallel configuration was mainly influenced by the higher output current, while the difference in voltage was relatively insignificant. These findings contribute to determining a more optimal circuit configuration for the development of piezoelectric paving blocks as a renewable energy harvesting system based on mechanical pressure.
