This study applies the Mean Variance model, which aims to form an optimal portfolio composition in the health, property, and cyclical consumer sectors and combine the three sectors into one portfolio, then visualize its efficient frontier. This study analyzes the return profiles and compares the risks of each portfolio using alternative risk measures such as the Coefficient of Variation (CV), Value at Risk (VaR), and Conditional Value at Risk (CVaR). Daily closing price data for the three sectors listed on the Indonesia Stock Exchange (IDX) from March 2, 2020, to March 3, 2025, were used in this study. Stock selection was conducted using purposive sampling, followed by selecting seven stocks for optimization based on the lowest Coefficient of Variation (CV) value. Portfolio optimization analysis was conducted using the Python programming language with Visual Studio Code software. The findings of this study indicate that the combined portfolio incorporating the three sectors is the most efficient, with an expected return of 0.104%, standard deviation of 0.007, and alternative risk measures such as Coefficient of Variation (CV) 6.9328, Value at Risk (VaR) of -0.99%, and Conditional Value at Risk (CVaR) of -1.44%, which are lower than those of single-sector portfolios. Visualization of the efficient frontier curve confirms that the combined portfolio offers better results in terms of risk and return. The results of this study indicate that cross-sector diversification can significantly reduce risk and prevent significant losses.

This study aims to design and analyze a more effective Islamic Religious Education (IRE) learning model by integrating humanistic principles with Islamic spirituality. This integration is important because traditional IRE learning has largely focused on cognitive mastery, while affective and spiritual dimensions have not been developed optimally. Using a descriptive qualitative method with a literature study approach, this research reviews books, academic journals, and previous studies relevant to humanistic and spiritual-based learning. Content analysis is then employed to identify thematic patterns that explain how both approaches can strengthen one another within the IRE learning process. The findings reveal that integrating humanistic and spiritual elements results in deeper, more reflective, and transformative learning experiences. The humanistic approach allows students to develop self-awareness, value personal experiences, and fulfill emotional needs, whereas Islamic spirituality reinforces the values of tawhid, moral character, and divine consciousness. Teachers play a crucial role as facilitators who guide students through learning experiences that combine humanistic empathy and Islamic values. Authentic assessment methods such as reflection journals, moral portfolios, and behavioral observations are used to evaluate student development. Overall, this study concludes that an IRE learning design grounded in both humanistic and spiritual approaches can foster intellectually capable, emotionally mature, and spiritually grounded learners who are well-prepared to face the challenges of the digital era.

The digital transformation era requires university students to develop digital literacy competencies that not only support academic activities but also serve as essential capital for entering the workforce and pursuing entrepreneurship. One relevant professional platform to enhance career readiness is LinkedIn, which serves as a medium for both personal branding and professional networking. This community service aimed to improve students’ digital literacy and career readiness through mentoring sessions on LinkedIn account optimization. The program involved the students from the English Education (TBI) and Physics Education (TFS) study programs at the Faculty of Tarbiyah and Teacher Training, UIN Palangka Raya, comprising prospective teachers and professionals across various disciplines. The implementation was carried out through tutorials and direct mentoring in two sessions, covering account creation, developing professional headlines and summaries, adding skills and experiences, and uploading simple portfolios. The results indicated that all participants successfully created or improved their LinkedIn profiles, actively engaged in the activities, and demonstrated a greater awareness of the importance of a professional digital identity, which can be seen from the students’ participation, the quality of the profiles produced, and their commitment to continuously developing their LinkedIn accounts. The program highlights LinkedIn’s strategic role in strengthening digital literacy and career readiness among university students in the global era.

This program was designed to improve the financial literacy of Generation Z, with a specific focus on members of the Maluku Protestant Church Youth Movement (AMGPM) in Poka Village. Initial assessments indicated that most participants had limited financial knowledge, with fewer than 30% understanding basic investment concepts. The initiative employed socialization and simulation methods to educate participants on investment principles, introduce regulated investment applications approved by OJK and BAPPEBTI, and promote secure online investment strategies. Evaluation findings revealed significant progress, with 40% of participants showing improved financial literacy. Additionally, over 75% successfully performed investment steps during simulations, and 85% expressed increased confidence in beginning their investment journey. While the program effectively enhanced participants' understanding, continued training is necessary to ensure long-term impact, particularly in the areas of portfolio diversification and risk management, which are critical for building sustainable and resilient investment practices.

This study examines and compares the Capital Asset Pricing Model (CAPM) with the Sharia Compliance Asset Pricing Model (SCAPM) in constructing an optimal stock portfolio based on the sharia stock index on the Indonesia Stock Exchange, specifically the Jakarta Islamic Index (JII), during the 2019–2023 period. The primary aim is to evaluate whether the SCAPM, which incorporates mudharabah profit-sharing returns in place of the risk-free rate, offers more relevant insights for Muslim investors compared to the CAPM. Utilizing a quantitative approach and a two-step regression method, the research develops an optimal portfolio by calculating stock betas and analyzing the relationship between systematic risk and expected returns. The findings reveal that neither the CAPM nor the SCAPM models are valid for predicting risk and expected returns for the JII's optimal stock portfolio. This study is intended to guide sharia-compliant investors in making informed decisions and assist investment managers in designing strategies aligned with Islamic financial principles.

Global Youth Action is a company engaged in youth empowerment with a focus on supporting the achievement of Sustainable Development Goals (SDGs) through the collaboration of various youth movements in Indonesia and internationally. However, the company still faces challenges in terms of infrastructure and information system (IS) applications that are not fully capable of supporting business processes optimally. One of the main obstacles is the limited human resources who have expertise in managing SI and information technology (IT) effectively.

This study examines the impact of interest rates and inflation during the 2019-2023 period on asset allocation strategies in Indonesia's investment portfolio. Investment decisions are heavily influenced by two macroeconomic components, namely interest rates and inflation. These factors mainly affect how assets comprise a portfolio. In this study, data on Bank Indonesia's benchmark interest rate and the national inflation rate over the past five years are analyzed to see the pattern of change and its impact on asset allocation strategies, which include stocks, bonds, property, and other assets. The results show that rising interest rates significantly encourage people to shift from high-risk assets (e.g. stocks) to safer assets (e.g. bonds and deposits). Meanwhile, high inflation triggers an increased allocation to physical assets such as property and gold as a hedge against declining purchasing power. This research provides insights for investors to adjust their investment portfolios based on macroeconomic dynamics, especially in the face of interest rate volatility and inflation. The findings also highlight the importance of flexibility and diversification in asset allocation strategies to achieve optimal investment objectives amid economic uncertainty. The conclusion of this study confirms the importance of understanding interest rate and inflation dynamics in formulating effective investment strategies in Indonesia. The implications of these findings can be used by investors and policymakers in designing better monetary policies and investment strategies, in order to maintain national economic stability.

Parties or companies that manage their customers' managed funds into various investment instruments are known as investment managers in mutual funds. Mutual funds are highly recommended for novice investors because of their low capital and risk compared to other types of investment. In managing mutual funds, the investment manager is responsible for the securities portfolio and the collective investment portfolio. The portfolio is intended to minimize the risks that occur when managing investments, with the existence of a portfolio it is expected that the returns expected by investors can be achieved optimally in managing mutual funds. In managing mutual funds, there are always mistakes in anticipating the return expected by investors. Default is one example of an error that occurs. There are two causes of default: debtor (customer) and force majeure (overmacht or force majeure).
