This study aims to determine the effect of fintech, the amount of money in circulation, interest rates and economic growth on the analysis of digital economic trends on monetary policy in Indonesia. There are four variables in this study, namely fintech, the amount of money in circulation, interest rates and economic growth. The analysis method used is Vector Autoregression with the Impluse Response Function test or abbreviated as IRF and the Forecast Error Variance Decomposition test commonly abbreviated as FEVD, stationarity test, cointegration test, lag structure stability test and optimal lag length test. There is a contribution from each variable to the variable itself and other variables, according to the results of the Vector Autoregression study with a lag basis of 2. In addition, the results of the Vector Autoregression analysis show that the past variable (t-1) contributes to the current variable both to the variable itself and to other variables. The results of the analysis show that there is a reciprocal relationship between the variables. By using response function analysis, we can see if there is a response from other variables to changes in one variable in the short, medium, or long term. In addition, we know that the stability of all variables is formed in the short, medium, and long term. According to the Variance Decomposition Analysis, factors such as Fintech and Money Supply contribute the most to the variable itself. However, other variables that have the greatest influence on the variable itself and are supported by other variables in the short, medium, and long term are economic growth and interest rates are most influenced by Fintech.

The money supply can affect other economic variables, such as output and prices, create stability in the economy and help achieve the ultimate goal of monetary policy, namely the stability of inflation and exchange rates.  The level of the exchange rate by the monetary authority must be kept stable because an unstable exchange rate, especially one that experiences a sharp depreciation, can have financial crisis implications. This research approach was associative/quantitative research. The data used in this study are secondary data taken and processed from Bank Indonesia (BI) and the Central Statistics Agency (CSA) from 2013-2023 (11 years). Based on the results of regression analysis shows that the variable money supply, exchange rates, and interest rates simultaneously affect the inflation variable. Based on the results of regression analysis shows that the variable money supply has a positive and significant effect on inflation. Based on the results of regression analysis, the exchange rate variable has a negative and significant effect on inflation. Based on the regression analysis, the interest rate variable has no statistical effect on inflation.

The Suez Canal has played a significant role in assisting and expediting the delivery of heavy goods on cargo ships from Asia to Europe, accommodating 12 percent of total global trade. The Suez Canal is a very important source of foreign currency for Egypt, a country that is still grappling with a variety of long-standing economic problems. Since October 2023, Yemen's Houthi group has been targeting ships in the Red Sea that it claims are connected to Israel in solidarity with Palestinians facing Israeli attacks in the Gaza Strip. This ongoing tension in the Red Sea not only impacts the Suez Canal, but also the maritime transportation market, trade movements, and international supply chains, as taking alternative routes means increasing shipping time and operating costs. Despite its important role as an international shipping lane, The Suez Canal has experienced a decline in status on the global stage due to various geopolitical events and economic crises that have occurred. This study aims to analyze the reciprocal relationship between international market dynamics and the strategic role of the Suez Canal. The chapter begins with an analysis of the impact of the Palestinian-Israeli conflict on international trade flows through the Suez Canal, followed by a discussion of the impact of the global economic crisis and conflict mitigation efforts on maritime security of shipping traffic. Finally, this chapter provides solutions that can be offered from the perspective of maritime security theory and international conflict theory.

This study examines how women entrepreneurs in Micro, Small, and Medium Enterprises (MSMEs) in the creative economy sector leverage digital technology to strengthen their roles in the urban tourism ecosystem. Using a qualitative approach supported by secondary data and non-intervention observations over six months in South Jakarta, the study analyzes the dynamics of digital adoption, the cultural value of creative products, and structural barriers affecting women's entrepreneurial experiences. The findings reveal that digital utilization is most prominent on easily accessible platforms such as Instagram, TikTok, and WhatsApp, while the use of more complex tools, such as marketplaces, websites, and analytics, remains limited. Women’s creative products, in subsectors like culinary, crafts, fashion, and others, prove to enrich the tourism experience and reinforce the city's destination identity. However, low digital literacy, minimal mentoring, and weak integration into the formal tourism supply chain hinder the optimization of these potentials. Additionally, the digital adoption patterns found support the Technology Acceptance Model's explanation that the perceived ease of use is a key factor in early technology adoption. This study fills an important gap in the literature by linking gender issues, digital transformation, the creative economy, and urban tourism within a unified framework. The research emphasizes the importance of strengthening digital capabilities and structured collaboration between women-led MSMEs and tourism stakeholders to enhance the sustainable competitiveness of destinations.
