This study examines the determinants of the Jakarta Composite Index (JCI) based on three main macroeconomic factors namely inflation, the USD/IDR exchange rate, and the SBI interest rate (BI Rate) covering the period January 2020 to December 2025, in the context of post-COVID-19 pandemic recovery and global economic turmoil. A quantitative approach was employed using the Ordinary Least Squares (OLS) method, with 72 monthly observations derived from secondary data sourced from official institutions including Bank Indonesia (BI), the Central Statistics Agency (BPS), the Indonesia Stock Exchange (IDX), and the Financial Services Authority (OJK). Classical assumption tests were applied comprising the Jarque-Bera normality test, Variance Inflation Factor (VIF) for multicollinearity, Breusch-Godfrey for autocorrelation, White Test for heteroscedasticity, and Ramsey RESET for model specification. Partially, inflation, exchange rate, and BI Rate each demonstrate a positive and significant effect on the JCI (p < 0.05). Simultaneously, all three variables exert a significant combined influence on the JCI, with a coefficient of determination R² = 0.4414, indicating that the model explains 44.14% of the variation in the JCI. The remaining 55.86% is attributed to other variables outside the model. Classical assumption test results reveal violations of normality, autocorrelation, and heteroscedasticity assumptions, although the model is free from multicollinearity. These findings confirm that Bank Indonesia's monetary policy has a significant and measurable impact on capital market performance. Further research is recommended using more advanced time series models such as GARCH or VECM to address violations of classical assumptions and improve estimation efficiency.

The need for housing is increasingly pressing with population growth and urbanization, while affordability remains a challenge for single-income households. The purpose of this investigation is to assess the impact of price also location on home purchase decisions using a literature review. This approach involves reviewing, analyzing, and synthesizing various relevant literature sources, such as scientific journals, books, undergraduate theses, also previous investigation reports that discuss factors influencing home purchase decisions. The study concludes that price plays a positive also significant role in home purchase decisions, as consumers prefer homes with prices commensurate with their purchasing power and the quality offered. Location has also been shown to influence decisions, particularly when housing is conveniently situated at a key location  and the availability of public facilities. However, certain studies indicate that price and location are not always the primary determinants of decision-making, as other variables such as promotion, brand image, product quality, and lifestyle also play a role.

Investment decisions in pharmaceutical manufacturing companies listed on the Indonesia Stock Exchange (IDX) are influenced by fundamental analysis and stock price fluctuations. Stock prices reflect market perceptions shaped by profitability, liquidity, and capital structure. This study examines the effects of Return on Assets (ROA), Current Ratio (CR), and Debt-to-Equity Ratio (DER) on stock prices, both partially and simultaneously. Using a quantitative approach, the study analyzes secondary data from audited financial statements and stock prices of 12 pharmaceutical companies during 2022–2024, totaling 36 observations. Panel data regression with EViews 12 is applied. Results show that ROA and DER have positive and significant effects on stock prices, while CR has a negative but insignificant effect. Simultaneously, all three variables significantly influence stock prices, with an adjusted R² of 73%, indicating strong explanatory power. Profitability (ROA) is the most influential factor, followed by capital structure (DER), while liquidity (CR) shows no significant impact.

This literature study aims to analyze the strategies of local cosmetic brands in providing product variants for different skin types, setting affordable prices for the teenage segment, and minimizing side effect risks to increase purchase intention among beginner users. The method used is qualitative library research with a thematic synthesis approach following systematic literature review procedures. The results indicate that complete product variants enable beginner users to find products suitable for their skin conditions, reducing confusion and increasing confidence. Affordable prices are crucial for the teenage segment with limited budgets, allowing them to try products without excessive financial burden. Minimizing side effect risks through safe formulations, dermatological testing, ingredient transparency, and usage education builds a sense of security essential for beginner users. These three strategies are interconnected and collectively create a foundation of trust that drives purchase intention. Beginner users who feel their needs are understood, products are affordable, and risks are minimal will be more motivated to purchase and have the potential to become long-term loyal customers. This study contributes theoretically to enriching cosmetic marketing literature with a teenage and beginner user segmentation perspective and practically provides foundations for local brands in designing products, pricing strategies, and safety communications targeting this segment.

Exchange rates are a crucial indicator in an open economy, playing a significant role in influencing international trade, investment flows, and overall macroeconomic stability. This study aims to analyze the impact of rupiah exchange rate fluctuations on Indonesia’s economic growth during the period 2014–2023. The research employs a descriptive qualitative approach using secondary data obtained from official publications of Statistics Indonesia and Bank Indonesia. The main variables analyzed include the rupiah exchange rate against the United States dollar and Indonesia’s economic growth. The findings indicate that exchange rate movements are closely related to economic growth dynamics, particularly through international trade mechanisms, production costs, and the stability of the real sector. Depreciation of the exchange rate tends to enhance export competitiveness, but it may also trigger inflation due to rising import prices. Conversely, appreciation can help control inflation but may weaken export competitiveness. Therefore, maintaining exchange rate stability is essential to support sustainable economic growth and strengthen national economic resilience.

This study aims to analyze the effect of inflation and interest rates on the stock prices of banking companies listed in the IDX80 index on the Indonesia Stock Exchange for the 2019–2024 period. Research data were obtained from official reports of banking company stock prices as well as inflation and interest rate data from Bank Indonesia. The study used a quantitative approach with multiple linear regression methods through the SPSS application, and classical assumption tests were conducted as a requirement for analysis. The study population included all IDX80 banking companies, with a saturated sampling technique resulting in five banks that met the criteria during the study period. The results of the partial test indicate that inflation has a positive and significant effect on stock prices, while interest rates have a negative and significant effect on stock prices. This indicates that stable inflation can still improve the performance of the banking sector, while rising interest rates tend to depress stock prices due to increased borrowing costs and a shift in investment to other instruments. The results of the simultaneous test also show that inflation and interest rates together have a significant effect on the stock prices of IDX80 banking companies. The results show that inflation has a significant positive effect on stock prices with a significance value of 0.034, while interest rates have a significant negative effect with a significance value of 0.018. Simultaneously, inflation and interest rates have a significant effect on stock prices with a calculated F value of 14.549 > Ftable 2.70 and a significance of 0.000 < 0.05.

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.

This study aims to analyze the impact of inflation on the profitability of Micro, Small, and Medium Enterprises (MSMEs) operating in traditional markets. Inflation influences key business aspects, including rising production costs, declining consumer purchasing power, and instability in input prices, all of which can disrupt business performance. The research employed a quantitative approach using survey data collected from MSME actors to assess these effects. The findings reveal that inflation has a significant negative impact on MSME profitability, particularly through the reduction of profit margins. This occurs as businesses face higher raw material costs while simultaneously experiencing a decline in sales volume due to weakened consumer demand. As a result, many MSMEs struggle to maintain financial stability and sustain their operations under inflationary pressure. These findings highlight the need for adaptive strategies among MSMEs, such as cost efficiency and pricing adjustments. Additionally, the study offers important policy implications for the government to support MSMEs through targeted interventions, including price stabilization measures and financial assistance programs, in order to maintain business resilience and economic sustainability.

Business activities are essential for helping the economy of society function properly. When starting a business, people usually want to make money, but they are also supposed to follow good values, like being honest in their dealings. In real life, some businesses still do unfair things, like giving false information about products, changing prices unfairly, lowering the quality of goods, and using incorrect measurements when selling items. This research focuses on explaining what honesty means and how it should be used in business according to the principles of Islamic economics. The study uses a qualitative method called literature review, which involves looking at books, journal articles, and other sources that talk about Islamic business ethics. The results show that honesty is a key value in Islamic business because it helps build trust with customers, ensures fair deals, and creates positive relationships between sellers and buyers. The value of honesty in the business world can be demonstrated through transparancy of information about products, honesty in pricing, accuracy in measurement, and not hiding defects in the goods being sold. From an Islamic economics perpective, business activities should not only focus on material income, but also on the value of blessings, ethical responsibility, and mutual prosperity. Thus, the application of honesty in an important foundation for building fair, transparent bisuness practices that are in line with Islamic economic prinsiples.

Electricity dependence is increasing as people have easier access to electronic devices. However, this ease of access is not always accompanied by adequate energy literacy. In its Community Service program, Universitas 17 Agustus 1945 Jakarta helped to educate the residents in RW06 Kalibaru, Jakarta, about the safe and efficient use of electricity. This community service program was conducted through participatory seminar with a qualitative approach for residents. The activity used informal visual presentations and discussions in an informal atmosphere. The outreach program demonstrated residents' high enthusiasm for the efficiency of electrical equipment usage such as air conditioners, refrigerators, and water pumps. Through the discussion session, residents realized that using air conditioners with too low a power consumption actually leads to higher energy consumption because the compressor runs continuously. Participants understood that investing in automation concepts, such as using water reservoirs, provides significant long-term electricity cost savings. This outreach successfully shifted residents' paradigm from just simply seeking low prices to selecting devices with optimal capacity according to their needs. This education program demonstrates the effectiveness of energy literacy in improving electricity consumption habits at the household level. Therefore, simple technical understanding can boost family economic financial advantages through sustainable effective energy consumptions.

Local fashion businesses require accurate production cost calculations to ensure appropriate and sustainable pricing decisions. Problems often faced by small businesses is determining selling prices without comprehensive calculation of the cost of production. This study aims to analyze the calculation of the cost of production as the basis for determining the selling price at Voraya Wear, a student-based local fashion business developed through the Student Creativity Program (PKM). The research used a descriptive quantitative approach with direct practice methods. Data were collected through observation, documentation, and financial records, then analyzed using the full costing method to calculate the cost of production and the cost-plus pricing method to determine the selling price. The results show that the total production cost was Rp1,831,064 for 24 units, resulting in a unit cost of Rp65,757 for shirts and Rp86,832 for pants. By applying a profit margin of 30–40%, the business generated total revenue of Rp2,520,000 and a net profit of Rp688,936. These findings indicate that accurate cost calculation supports rational pricing decisions and ensures business profitability and sustainability.

Donorojo Village, Pacitan Regency, East Java, has significant agricultural potential, particularly in spice commodities. However, the utilization of spices by local farmers remains limited to the sale of raw materials in traditional markets at relatively low prices and with restricted market reach. In fact, spices have high economic value and strong potential to be developed into value-added products, such as herbal beverages. This community service activity aimed to enhance the knowledge and skills of the PKK women’s group in Donorojo Village in processing spice-based “biofarmaka” as an effort to empower the local economy and strengthen the spice value chain. The methods employed included lectures, demonstrations, and hands-on practice, conducted over five days at the Donorojo Village Hall and involving 20 participants. The products generated from this activity included “jahe gajah beverage”, “instan jahe merah”, “instan beras kencur”, and “instan kunir asem”. The results indicated an improvement in participants  understanding of the health benefits of spices, hygienic processing stages, and their ability to produce instant herbal beverage products. Furthermore, this activity has the potential to strengthen linkages between spice farmers as raw material suppliers and the PKK group as processing actors. The development of spice-based “biofarmaka” provides economic value addition, expands market opportunities, and encourages the growth of rural entrepreneurship. Therefore, spice-based “biofarmaka” processing training can serve as a strategy for rural agro-industry development that supports the improvement of economic stability in Donorojo Village.

Regional economic development requires a comprehensive understanding of the structure, potential, and dynamics of economic sectors so that formulated policies can be targeted and sustainable. Bojonegoro Regency as one of the regions in East Java Province has unique economic characteristics with the dominance of certain sectors, so it is necessary to conduct an in-depth analysis of the economic sectors that play a role in driving regional growth. This study aims to identify basic and non-basic sectors, analyze the dynamics of changes in economic sectors, and assess the sectoral competitiveness of Bojonegoro Regency compared to East Java Province. This study uses a quantitative approach with secondary data in the form of Gross Regional Domestic Product at constant prices by business field obtained from the Central Statistics Agency. The analytical methods used include Location Quotient, Dynamic Location Quotient, and Shift Share. The results show that the mining and quarrying sector remains the sector with the most dominant relative advantage in the economic structure of Bojonegoro Regency. However, the analysis of dynamics and competitiveness indicates that several non-extractive sectors are starting to show faster development and growth potential. This finding suggests an opportunity for transformation of the regional economic structure towards a more diverse pattern. The implications of this research emphasize the importance of regional economic development strategies that do not only rely on traditional leading sectors, but also encourage the development of more sustainable potential sectors.
