Abstract

Analysis of Optimal Portfolio Formation of Big Bank Stocks in LQ-45 Using the Elton and Gruber Model on the Indonesia Stock Exchange for the 2019-2023 Period. This study aims to analyze the management of stock portfolios on the Indonesia Stock Exchange using the Elton and Gruber Model, focusing on Big Bank stocks included in the LQ-45 stock index during the 2019-2023 period. This study uses monthly data for the 2019-2023 period, with data analysis techniques using Microsoft Excel. The results of this study found that there were 3 stocks included in the optimal portfolio with an Excess Return to Beta (ERB) value greater than the Cut-Off Rate (CI), namely; Bank Central Asia Tbk (BBCA), Bank Rakyat Indonesia Persero (BBRI) and Bank Mandiri (Persero) Tbk (BMRI). The results show that the optimal portfolio is formed by stocks that have high returns at relatively the same risk level.

Abstract

One of the measures taken is engaging professional consultants capable of providing business solutions, strategic analysis, and recommendations based on their expertise and experience. As business challenges grow more complex and technology advances, the demand for consulting services continues to rise, leading to increasingly intense competition among consulting firms. This study aims to examine the influence of service quality, corporate image, and marketing strategies on the decision to use consulting services, with selling price as a moderating variable, at PT Pelita Sarana Indotama. The study employed a quantitative approach involving 100 respondents selected through purposive sampling. Data analysis was conducted using PLS-SEM with SmartPLS 4.1.1.8. The results show that service quality and marketing strategy have a significant positive effect on the decision to use consulting services, while corporate image has no significant effect. Selling price also fails to moderate the relationship between these three variables and the decision to use consulting services. These findings are expected to provide input for the company in improving service quality and marketing strategy.

Abstract

Objective: This study aims to analyze the effect of profitability (return on assets) and liquidity (current ratio) on stock prices, with exchange rates as a moderating variable, for companies in the banking subsector of the financial sector listed on the Indonesia Stock Exchange (IDX) during the 2015–2024 period. The study employs an associative quantitative approach using panel data that combines cross-sectional data (10 banking companies) and time-series data (2015–2024), resulting in 100 observations. The sample was selected using purposive sampling and analyzed using panel data regression with the Random Effects Model (REM) assisted by Eviews-12. The results indicate that profitability and liquidity do not have a significant partial effect on stock prices. The exchange rate also fails to moderate the effects of profitability or liquidity on stock prices. The adjusted R-squared value of 35.63% indicates that the variables in this study can explain only a small portion of the variation in stock prices; thus, it is suspected that other, more dominant factors influence the movement of banking companies’ stock prices.

Abstract

This study aims to determine the influence of Work Motivation, Work Environment, and Job Satisfaction on Employee Productivity at PT. Nihon Seiki Indonesia. This research is motivated by the phenomenon of declining employee productivity as shown by the non-achievement of work targets in recent months. This problem indicates the possibility of a decline in internal quality that needs to be evaluated, such as low motivation, less supportive work environment conditions, and less than optimal job satisfaction. This decline can also have an impact on the company's overall performance, including in terms of efficiency, production quality, and customer satisfaction that are declining over time. The method used in this study is a quantitative method with a descriptive and verifiable approach. The data collection technique was carried out through the distribution of questionnaires to 90 employees as a sample of the total population of 115 employees working in the company. The research instrument was tested through validity and reliability tests. Data were analyzed using multiple linear regression analysis, t-test (partial), F test (simultaneous), and determination coefficient (R²) test, with the help of SPSS software version 26. The results of the study show that Work Motivation, Work Environment, and Job Satisfaction have a significant effect on Employee Productivity, both partially and simultaneously. These findings confirm that the increase in employee work productivity is not only dependent on external factors such as technology and management systems, but is also highly determined by internal factors that are directly related to individual comfort and satisfaction at work. Therefore, company management needs to focus more on efforts to create a conducive work environment, build strong motivation, and increase employee job satisfaction as a strategy to optimize productivity. In addition, continuous training and effective communication between teams also need to be improved to maintain morale, collaboration, and the achievement of overall organizational targets.
