This study aims to develop a strategic plan for Information Systems and Information Technology (IS/IT) at KR Hotel Palembang by applying the Ward and Peppard methodology. The analysis began with external environment assessment using the PEST framework and internal analysis through the MOST method and Value Chain model. The results were synthesized into a SWOT analysis to identify the organization's strengths, weaknesses, opportunities, and threats. From this, Critical Success Factors (CSF) were formulated to guide the determination of key information system needs. Application portfolio mapping was then conducted using the McFarlan Strategic Grid to classify systems based on their strategic impact. Findings indicate that KR Hotel has strong potential in leveraging digital technologies but faces challenges such as the absence of integrated systems across departments and limited IT training for staff. To address these issues, an integrated system named ZKBiolock was proposed, encompassing modules such as hotel management, financial management, customer relationship management (CRM), human resource training systems, digital promotion, and internal network monitoring and control. This strategic plan is supported by a comprehensive database design, network topology, human resource and infrastructure analysis, investment budgeting, and Return on Investment (ROI) evaluation. The proposed strategy aims to enhance the efficiency and effectiveness of the hotel's operational management.

This study aims to analyze the effect of global diversification, exchange rates, and interest rates on the performance of mixed mutual funds in Indonesia during the period 2020–2024. The method used is a quantitative approach with the Partial Least Squares–Structural Equation Modeling (PLS-SEM) technique, using secondary data from the Financial Services Authority, Bank Indonesia, and Bareksa. The sample consists of three mixed mutual fund products that meet the criteria of portfolio data completeness, net asset value, and performance report publication. The results show that exchange rates have a positive and significant effect on mutual fund performance, indicating that exchange rate fluctuations play an important role in determining changes in portfolio returns. The global diversification variable proved to have no significant effect, illustrating that exposure to international markets has not provided stable benefits in improving the performance of mixed mutual funds. Interest rates also did not show a significant effect because the composition of mixed portfolios was able to withstand the impact of monetary policy changes. Simultaneously, the three independent variables were able to explain 66.7 percent of the variation in mixed mutual fund performance, indicating that macroeconomic dynamics and portfolio strategies have an important contribution in influencing the performance of this collective investment instrument.

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 examines the comparative volatility of gold and Bitcoin over the period January 2020 to August 2025, using monthly data and employing descriptive statistics, the Augmented Dickey-Fuller (ADF) test, GARCH (1,1), and the Dynamic Conditional Correlation Generalized Autoregressive Conditional Heteroskedasticity (DCC-GARCH) model estimated with EViews 13. The results show that Bitcoin is characterized by extreme and persistent volatility, reflecting its speculative nature, whereas gold remains stable and functions as a conventional safe-haven asset. Correlation analysis indicates that the relationship between gold and Bitcoin is generally weak but dynamic, as the strength and direction of their co-movements change across different market conditions. These findings highlight the potential role of gold as a hedge and Bitcoin as a speculative diversifier, offering insights for portfolio diversification and risk management. These results also suggest that investors should carefully consider their risk tolerance and investment horizon when allocating assets between traditional and digital commodities.

Indonesia’s Islamic capital market has experienced remarkable growth in recent years, evidenced by the increasing number of investors and the rising market capitalization of Sharia-compliant stocks. This article aims to analyze the performance and management strategies of Sharia stock portfolios by reviewing academic literature published in Indonesia between 2019 and 2024. Utilizing a literature review methodology, the study compares the return and risk characteristics of Sharia stocks with those of conventional stocks. It also evaluates the applicability and effectiveness of classical portfolio theories—namely, the Markowitz Model and the Single Index Model—in managing Sharia-compliant investments. The findings reveal that Sharia stock portfolios often perform competitively and tend to exhibit greater resilience and stability during financial crises. This resilience is attributed in part to the rigorous stock screening mechanisms that comply with Islamic principles, excluding sectors and companies that do not meet Sharia criteria. Additionally, various macroeconomic factors such as inflation, interest rates, exchange rates, and global economic fluctuations are found to impact the performance of Islamic stock portfolios. The article highlights that while Sharia investments align with ethical and religious values, they also offer practical advantages in risk management and diversification. Furthermore, digital technology and fintech innovation are seen as essential tools to enhance transparency, accessibility, and investor engagement in the Islamic capital market. The study concludes that the development of Sharia-compliant stock investments in Indonesia holds promising potential, especially if accompanied by improved financial literacy, inclusive investor education, and stronger technological infrastructure. This paper offers valuable insights for policymakers, market regulators, and investors interested in promoting sustainable and faith-based financial practices within Indonesia’s rapidly evolving capital market ecosystem.

This study investigates the potential role of the Jakarta Islamic Index (JII) as a hedging instrument and safe haven asset against the Indonesia Composite Index (IHSG) during the period from January 2020 to April 2025, a time characterized by elevated market volatility. The main objective is to determine whether sharia-compliant stocks in Indonesia offer diversification benefits during periods of financial stress. Utilizing daily closing prices converted into log returns, the study employs the Asymmetric Dynamic Conditional Correlation Generalized Autoregressive Conditional Heteroskedasticity (A-DCC GARCH) model to capture time-varying correlations between JII and IHSG. Prior to applying the model, standard diagnostic tests were performed to ensure data quality, including tests for stationarity, autocorrelation, and ARCH effects.Empirical results reveal a persistently high correlation between IHSG and JII, with an average of 0.826 and values exceeding 0.95 during periods of market turbulence. These findings indicate that JII does not fulfill the characteristics of a hedge or safe haven asset. A robustness analysis using extended data from 2010 to mid-2025 further supports the conclusion, showing the continued presence of strong comovement between the two indices across different market regimes. This suggests a structural relationship rather than one driven solely by crisis events. The high correlation may be attributed to overlapping index constituents and similar investor responses to market shocks. These results challenge the prevailing notion that Islamic indices inherently offer protection during downturns. As such, investors seeking to mitigate portfolio risk may need to look beyond domestic sharia equities and consider broader asset classes or international diversification. Future research is encouraged to explore cross-market and multi-asset safe haven properties, especially in the context of emerging economies.

This study examines the impact of murabahah contracts on profitability in the Islamic banking sector in Indonesia, especially in Islamic Commercial Banks. In this study, Return on Assets is used as the main indicator to measure the level of bank profitability. Multiple linear regression is used to empirically test the relationship between murabahah financing and Return on Assets. The results of the study indicate that murabahah financing has a significant and positive effect on Return on Assets. This indicates that the higher the level of murabahah financing disbursed, the greater the increase in profitability of Islamic Commercial Banks. This finding strengthens the evidence in previous literature regarding the importance of the role of Islamic financing product strategies in improving the results of Islamic banking financial institutions. As a result, this study emphasizes the importance of optimizing financing strategies based on murabahah contracts as a major component in the product portfolio of Islamic Commercial Banks. Therefore, to improve competitiveness, efficiency, and create sustainable financial stability in the national Islamic banking system, it is necessary to develop and implement more effective and efficient murabahah contracts by all Islamic banking institutions in Indonesia and work well by all Islamic banking institutions in Indonesia.

This research aims to analyze the impact of Environmental, Social, and Governance (ESG) integration on the risk-return profile of the investment portfolio of PT Unilever Indonesia Tbk. The research employs a quantitative method with a case study approach, utilizing historical data from the period 2017-2021. The data is analyzed to identify the relationship between ESG scores and portfolio returns, as well as portfolio risk. Regression analysis and t-test are employed to test the research hypotheses. The findings reveal a positive and significant relationship between ESG integration and the investment portfolio's return of PT Unilever Indonesia Tbk. The regression coefficient of 0.154 indicates that each one-point increase in the ESG score will result in an average increase of 0.154% in the investment portfolio return.

This study examines the investment preferences of Generation Z, specifically their inclination toward gold investment. The research is based on secondary data obtained through literature studies focusing on Gen Z's investment behavior. The findings indicate that Gen Z tends to favor gold as an investment option due to several compelling reasons. One of the main motivations is the potential for profit, as gold is considered not only a stable asset but also one that offers promising long-term returns. In addition, gold is perceived as a safe investment amid economic uncertainty. Other influencing factors include: (1) security and stability, (2) ease of access and purchase through digital platforms, (3) long-term investment potential, (4) diversification of investment portfolios, (5) historical value and its role as a symbol of security, (6) easy and flexible transactions, and (7) protection against inflation. These factors highlight the strategic thinking of Gen Z investors who seek both financial security and growth through alternative investment instruments such as gold.

This study aims to compare the performance of PT Metro Healthcare Indonesia, PT Kalbe Farma Tbk, PT Indocement Tunggal Prakarsa Tbk, PT Siloam International Hospitals Tbk, and PT Hetzer Medical Indonesia Tbk. The focus of the research is the analysis of financial and operational performance to provide an in-depth understanding of the companies' competitiveness and efficiency within their respective sectors. The study employs a quantitative method with a descriptive-comparative approach. Secondary data were collected from the annual financial reports of each company over a specific period. The analysis was conducted using key financial ratios such as Return on Equity (ROE), Debt to Equity Ratio (DER), and Current Ratio (CR). Additionally, an operational performance trend analysis was performed to understand the comparative effectiveness of the companies in resource management. The results of the analysis indicate significant differences in financial performance between companies operating in the healthcare sector (PT Metro Healthcare Indonesia, PT Kalbe Farma Tbk, PT Siloam International Hospitals Tbk, and PT Hetzer Medical Indonesia Tbk) and those in the building materials sector (PT Indocement Tunggal Prakarsa Tbk). Companies in the healthcare sector tend to have higher profitability ratios compared to those in the building materials sector, although there are variations in debt and asset management efficiency. These performance differences can be attributed to underlying industry factors such as market demand, levels of innovation, and government policies. Companies in the healthcare sector benefit from growth driven by increasing public demand for healthcare services. In contrast, the building materials sector is more vulnerable to economic fluctuations and infrastructure investments. This study concludes that industry sectors and business models have a significant impact on companies' financial performance. Healthcare sector companies demonstrate more stable and promising performance compared to the building materials sector. This study is expected to provide insights for investors in selecting suitable investment portfolios.

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.

This literature study aims to introduce the main fundamental analysis and stock valuation methods that daily equity traders apply in choosing stocks for their active equity portfolios. Daily equities traders rely mostly on technical charts and other tools to identify patterns that can suggest potential activity without assessing a stock’s intrinsic value for trading decisions. Chart analysis is designed to find trades with high probability outcomes by establishing precise price targets. The goal of this technical paper is to emphasize the significance of fundamental analysis in the investment choices of daily traders. Fundamental analysis is based on the careful comparisons of a stock’s intrinsic value to the current market price. If the stock’s intrinsic value is higher than the market price, it is reasonable for a fundamental investor/trader to purchase the stock. This paper endorses the idea that using both investment techniques would result in more successful investing decisions for equities traders.

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).
