This study aims to analyze the concept of consumer demand in the perspective of Islamic economics with a focus on the influence of spiritual values ​​on the consumption behavior of Muslims. The academic problem underlying this study is the gap between the values ​​of Islamic teachings that emphasize simplicity, blessings, and spiritual responsibility, with the social reality of Muslims who often exhibit consumptive behavior and follow the flow of modern capitalism. This study uses a qualitative approach with library research methods, reviewing various literature related to the concept of consumption in Islamic economics, maqashid al-syari'ah, and spiritual values ​​such as halal, thayyib, qana'ah, wara', and zuhud. The results of the analysis show that spiritual values ​​have a significant role in shaping consumer demand that is not only oriented towards material satisfaction, but also towards blessings and social responsibility. Demand in Islamic economics is positioned as a moral and worship activity, not merely a rational economic decision. Consumption based on spiritual values ​​is also positively correlated with inner peace and mental health of consumers. Therefore, internalization of Islamic values ​​in consumption behavior is believed to be able to realize a fair, sustainable, and falah-oriented economic system (happiness in the world and the hereafter).

Digital transformation has reconstructed the marketing landscape, presenting TikTok as a narrative and affective space in shaping consumption decisions. This study investigates the interaction between Storytelling Marketing (STM), Electronic Word of Mouth (e-WOM), and Fear of Missing Out (FOMO) in mediating One Piece comic purchase intention. With a PLS-SEM approach to 385 respondents, it was found that STM and e-WOM not only have a direct impact on purchasing decisions, but also form a psychological resonance in the form of FOMO which strengthens consumptive urges. TikTok in this case is not just a medium, but an affective field where perceptions, emotions, and social impulses intertwine, blurring the line between narrative and economic decisions. This finding confirms the role of content strategy as a construction of meaning that activates symbolic ownership through collective emotional urgency.

The fast-paced modern lifestyle has led teenagers to favor fast food over healthier home-cooked meals. This study aims to analyze the effects of fast food consumption on obesity risk among adolescents through a review of 20 relevant studies. The findings indicate that excessive consumption of fast food, along with low physical activity and social influences, significantly contributes to the increasing rates of adolescent obesity in Indonesia. Key factors include easy access, affordability, aggressive marketing, sedentary lifestyles, and a lack of nutritional education. As a result, there is a heightened risk of degenerative diseases such as type 2 diabetes, hypertension, and heart disease, as well as psychological issues related to low self-esteem. To address the rising trend of adolescent obesity, comprehensive interventions are necessary, including nutrition education, dietary regulation, and the promotion of active lifestyles.

Global economic issues have significantly impacted national economic progress in recent decades, especially for developing countries such as Indonesia.  Currency exchange rates are one of the main variables that influence this economic process.  The performance of a country's external sector is largely determined by the exchange rate, which also affects a number of other macroeconomic factors.  The purpose of this study is to see how much Indonesia's economic growth is affected by the exchange rate between 1980 and 2023. Data from government agencies including the Central Bureau of Statistics and Bank Indonesia are used in this quantitative approach using a literature study approach.  The findings show that changes in the value of the rupiah, especially when depreciation occurs, have a significant influence on a number of economic factors, such as imports, exports, inflation, domestic investment, and consumption.  The competitiveness of Indonesian export goods in the global market increases with the depreciation of the exchange rate. At the same time, however, it also leads to higher prices for imported goods, increases the burden of foreign debt, and depresses people's purchasing power and domestic investment activity. The last five years of data reflect the fluctuating pattern of Indonesia's international trade, which is closely related to exchange rate conditions and global economic dynamics. Exchange rate instability creates economic uncertainty, which can hamper long-term growth. Therefore, stabilizing the exchange rate and strengthening the export sector are important strategies, supported by monetary and fiscal policies that are adaptive to global changes.

Global climate change demands immediate technological advancements, particularly in the transport industry that continues to use fossil fuels. One viable solution is to reduce the size of vehicle engines to make them more fuel-efficient and lower carbon emissions. The purpose of this research is to assess the effect of reducing engine size on fuel consumption and CO₂ emissions in low-cost green car hatchbacks in Indonesia. The technique employed is straightforward analytical modeling, employing Pearson correlation analysis and linear regression among three significant variables: engine capacity, fuel economy, and CO₂ emission. The data are obtained from the technical specifications of four hatchback automobile models, all of which have an engine capacity of less than 1,200 cc. Findings indicate that smaller engine capacity is accompanied by greater fuel economy and lower carbon emissions. The lowest engine size of 998 cc is used in the Toyota Agya, which demonstrates the most efficient fuel and lowest emissions. The statistical analysis shows that there is an inverse relationship between engine size and fuel efficiency, but a positive relationship between engine size and CO₂ emissions. The limitation of sample size causes reduced statistical power of the model. In conclusion, engine downsizing can prove to be a productive approach in promoting green schemes, but additional research with a larger data set and other determinants must be undertaken to establish a more advanced and precise model.
