Abstract

Financial literacy is an important skill needed by individuals to manage their finances wisely. However, the level of financial literacy in Indonesia still needs to be improved even though the financial inclusion rate continues to grow. This study aims to explore the importance of integrating financial literacy into the school curriculum and compare its implementation in various countries. Using a literature study method with a descriptive-critical approach, this study analyzes various academic sources and policies related to financial education. The results show that countries such as Finland, Australia, Belgium, and the United States have successfully implemented financial literacy systematically in their curriculum, with a practice-based and technology-based approach. In Indonesia, the main obstacles to implementing financial literacy in schools include limited resources, lack of teacher training, and social norms that still consider discussions about finance as taboo. Although several initiatives have been carried out, such as adjusting the curriculum with financial material across subjects, their effectiveness is still limited. Therefore, a more contextual learning model is needed and policies that support the implementation of comprehensive financial literacy in schools. Integrating financial literacy into education will help equip the younger generation with better economic skills, ensure their readiness to face the challenges of the digital economy, and contribute to the stability of the national economy in the future.

Abstract

Islamic tourism has gained significant attention as a driver of community-based economic development, with mosques playing a central role in religious, social, and economic activities. One notable example is Jogokariyan Ramadhan Village (JRV), an annual program that attracts thousands of visitors through religious events and MSME-driven markets. This study aims to analyze the sustainability of JRV in economic, social, and environmental aspects as a community-based religious and economic tourism destination. Using a qualitative approach with a case study method, data were collected through in-depth interviews, participatory observation, and document analysis. Respondents included mosque managers, MSME actors, and tourists, with data analyzed using qualitative descriptive techniques based on the Triple Bottom Line model (economic, social, and environmental). The findings indicate that JRV has successfully improved the local economy through active MSME participation and transparent mosque fund management. Socially, JRV fosters strong community cohesion through mutual cooperation and empowerment initiatives. However, challenges persist, including a decline in economic activity after Ramadan and the environmental impact of market waste. The study underscores the importance of mosque-based economic initiatives in sustaining local businesses beyond Ramadan, demonstrating how religious tourism can be a catalyst for long-term economic resilience. Additionally, it highlights the need for improved waste management strategies to mitigate the environmental impact of large-scale religious events. To address these challenges, this study recommends strategies for economic diversification, the digitalization of MSME marketing, and the optimization of social programs to extend JRV’s positive impact throughout the year. By implementing these measures, JRV can serve as a model for sustainable religious tourism that can be replicated in other regions.

Abstract

Investment involves growing personal wealth through asset value appreciation. From 2020 to 2024, Indonesians’ interest in investing rose by 228.52%. However, the 2022 National Survey on Financial Literacy and Inclusion (SNLIK) showed a decline in the capital market literacy index, dropping from 4.92% in 2019 to 4.11% in 2022. This highlights a gap between investment interest and financial knowledge. To address this issue, research was conducted to optimize portfolio formation using the K-Means and Markowitz methods, with risk measured through Value at Risk (VaR) Backtesting. The Markowitz method minimizes risk for a given return level, helping investors meet financial goals efficiently. The analysis used stocks from the IDX30 index, known for liquidity, strong fundamentals, and large market caps. The study produced an optimal portfolio with a 16% expected return and a 32.827% annual risk. The stock allocation is: AKRA (8.444%), AMRT (6.135%), BBCA (39.900%), BMRI (17.385%), BBNI (11.410%), ICBP (14.448%), and MEDC (2.278%). The portfolio's maximum loss was -1.628%, lower than any individual stock, demonstrating the model's accuracy and reliability in managing risk while maintaining return potential.

Abstract

Abstract: Waqf is a unique Islamic economic instrument that functions to distribute social benefits sustainably. However, the management of waqf in Indonesia faces challenges, particularly related to certification that provides legal certainty over waqf assets. This certification is crucial for optimizing the utilization of assets and enhancing transparency and accountability in their management. Without certification, waqf assets are vulnerable to ownership disputes and ineffective management. The waqf certification policy in Indonesia has evolved since the issuance of Government Regulation No. 28 of 1977, with various regulations released by the government to expedite the registration and certification process of waqf land. This study aims to identify the challenges and opportunities within the waqf certification policy and provide recommendations for more efficient policy development towards sustainable development. The findings indicate that despite existing barriers in the certification process, there are also opportunities to improve waqf management through collaboration among institutions and increased public awareness regarding the importance of certification

Abstract

PT Petrokimia Gresik is the most complete fertilizer producer in Indonesia and produces various types of fertilizers. NPK is a fertilizer that contains nitrogen (N) to make plants greener, phosphorus (P) to stimulate root growth, and potassium (K) to make plants more upright and sturdy. This study aims to determine the optimum value of using sulfuric acid, phosphoric acid, and ammonia so as to obtain the best value in producing NPK fertilizer. This research method uses quantitative descriptive research methods by collecting secondary data, namely the use of sulfuric acid, phosphoric acid, and ammonia for a period of 1 year. Researchers use multiple regression analysis to determine whether or not there is an influence between the three variables to be studied, then the data is processed and analyzed to determine whether the regression model used is feasible to use before finally calculating the optimal point of NPK fertilizer production. The stages of data optimization in this study are the data collection stage, the data processing stage (descriptive data, parameter estimation, regression model), the data analysis and interpretation stage (F test, t test, IIDN assumption test for determining the optimum point), and the conclusion and suggestion stage. This study concluded that obtaining the optimum point for the amount of NPK fertilizer production can be done by regulating the use of phosphoric acid at 211.91 tons, Sulphuric acid at 844,099 tons, and ammonia at 308,055 tons. Total fertilizer production achieved with the use of optimum parameters amounted to 2085.38 tons.
