Purpose – This study analyzes the expected returns and risks associated with these stocks and identifies the optimal portfolio composition.Methodology – This study utilized operational data analysis and the Markowitz model to assess 30 stocks listed on the JII from 2017 to 2020. Through purposive sampling, 13 companies that met the specific sample criteria were selected for analysis.Findings – The analysis successfully identified an optimal portfolio composed of six stocks: ANTM (Aneka Tambang Tbk), ICBP (Indofood CBP Sukses Makmur), INCO (Vale Indonesia Tbk), KLBF (Kalbe Farma Tbk), PTBA (Bukit Asam Tbk), and UNTR (United Tractors Tbk). This portfolio demonstrates an expected rate of return ranging from 0.28% to 1.88%. Notably, the portfolio's overall risk value was calculated to be only 0.19%, which is significantly lower than the individual risk associated with any single stock within the portfolio.Implication – This study provides valuable insights for investors looking to build a balanced and Shariah-compliant investment portfolio, improving their understanding of expected returns and associated risks in Islamic financial markets.Originality – The abstract does not explicitly state the originality section. However, the unique combination of focusing on JII-listed Sharia stocks and applying the Markowitz model to identify an optimal portfolio can be inferred as the original contribution of this study. The context of Islamic financial markets distinguishes it from that of a general investment study.

This study aims to develop and examine the validity and reliability of a Counterproductive Work Behavior (CWB) instrument in the context of online motorcycle taxi drivers, encompassing two main dimensions: CWB directed at the organization (CWB-O) and CWB directed at individuals (CWB-I). Involving 1,416 participants from across Indonesia, the instrument was constructed based on the theory of Jex and Britt (2014) and tested using Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA). The CFA results indicate that the two-factor model has a good fit (CFI = 0.948; TLI = 0.941; RMSEA = 0.067), with high reliability (ω = 0.956 for CWB-O and ω = 0.759 for CWB-I). One item was removed due to the absence of significant loading on any factor. The instrument has been proven valid and reliable, and can be used as a tool to detect potential counterproductive behaviors among online drivers.

This study examines the moderating role of halal literacy in the adoption of halal packaged foods among Generation Z Millennials to promote sustainable consumption. The research expands the Theory of Planned Behavior (TPB) by incorporating the variable of halal literacy, a novel contribution to the literature. A quantitative approach was employed through a survey involving Generation Z Millennials selected via simple random sampling. Moderation regression analysis was conducted to assess how halal literacy influences the relationship between attitudes, subjective norms, behavior control, and the intention and adoption behavior of halal packaged foods. Findings indicate that halal literacy significantly strengthens the positive influence of attitudes towards halal packaged foods, enhances supportive subjective norms for adoption, and facilitates better behavioral control in selecting halal products. These results offer critical insights for developing effective educational and marketing strategies to enhance halal literacy among Generation Z Millennials, supporting sustainable consumption choices and promoting broader societal well-being.

This research aims to examine the extent to which the implementation of green accounting, environmental performance, and financial performance influences profitability and firm value in the basic materials sector listed on the Indonesia Sharia Stock Index (ISSI) during the period from 2019 to 2023. A quantitative approach with a descriptive design was applied. The data analyzed comprised 30 company observations representing 23 selected entities over five years. Data analysis techniques included simple and multiple linear regression through path analysis, Sobel test, and the calculation of the coefficient of determination. Hypothesis testing was conducted using t-test, F-test, and Sobel test, supported by EViews 12 Enterprise software. The findings indicate that green accounting significantly affects company profitability. In contrast, environmental performance and financial performance do not have a direct impact on profitability. However, when considered simultaneously, all three variables contribute to an increase in profitability. Additionally, the results show that environmental performance and profitability have a direct effect on firm value, while green accounting and financial performance do not exhibit a significant direct influence. Overall, all variables collectively influence firm value. Nevertheless, profitability does not act as a mediating variable in the relationship between green accounting, environmental performance, and financial performance on firm value.
