This study aims to analyze the effect of asset growth, capital structure, and asset structure on the profitability of PT Astra Graphia Tbk during the period 2016–2023. The research employs a quantitative approach with a causal research design using secondary data derived from the company’s quarterly financial statements. A total of 32 quarterly observations were selected through purposive sampling. Profitability is measured using Return on Equity (ROE), while data analysis is conducted using multiple linear regression. Prior to hypothesis testing, classical assumption tests including normality, multicollinearity, heteroskedasticity, and autocorrelation tests were performed to ensure the robustness of the regression model. The results indicate that asset growth, capital structure, and asset structure simultaneously have a significant effect on firm profitability. However, partially, only asset structure has a significant effect on profitability, while asset growth and capital structure show no significant influence. These findings suggest that efficient asset composition plays a more critical role in improving profitability than mere asset expansion or increased leverage. The managerial implication of this study highlights the importance of optimizing asset structure to enhance the firm’s ability to generate sustainable profits.

This study aims to investigate the empirical impact of population size and unemployment rates on economic growth in Central Kalimantan Province. The research focuses on the regional context of Central Kalimantan, utilizing a longitudinal dataset covering the eleven-year period from 2013 to 2024. To achieve the research objectives, the study employs quantitative analysis through the SPSS software package, utilizing multiple linear regression as the primary analytical tool to examine the relationship between the dependent variable (economic growth) and the independent variables (population and unemployment). The findings of the analysis reveal a divergent impact between the two independent variables. The results indicate that the population has a significant and positive influence on economic growth in Central Kalimantan during the 2013-2024 period, suggesting that demographic factors play a crucial role in regional expansion. Conversely, the unemployment rate was found to have no significant effect on economic growth within the same timeframe. Furthermore, the study conducted a comprehensive suite of classical assumption tests to ensure the validity and reliability of the statistical model. The results of these diagnostics confirm that the regression model adheres to the assumption of normality, shows no evidence of multicollinearity among the variables, and is free from symptoms of heteroscedasticity. Additionally, the analysis concludes that the model does not exhibit any issues related to autocorrelation. Consequently, the regression model is deemed statistically robust and appropriate for providing an accurate representation of the economic dynamics in Central Kalimantan.

The personal care product industry, particularly bath soap, is becoming increasingly competitive as public awareness of health and hygiene grows. Lifebuoy is a long-trusted bath soap brand, but according to data from the Top Brand Index 2021–2024, Lifebuoy is experiencing a significant downward trend. This situation indicates a problem in consumer purchasing decisions, making it crucial to examine the factors influencing it. This study aims to analyze the influence of advertising and brand image on purchasing decisions for Lifebuoy bath soap in Semarang City, with purchase intention as an intervening variable. This study used a quantitative approach with explanatory research. The population in this study was all Lifebuoy bath soap users in Semarang City.

Data analysis techniques used Descriptive Statistical Analysis, Measurement Model Evaluation (Outer Model), and Structural Model Evaluation (Inner Model) using the SmartPLS 0.4 application. The results of the study indicate that advertising has a direct influence on purchasing decisions, brand image has a positive and significant influence on purchasing decisions, advertising does not have a significant direct influence on purchase intention, brand image has a positive and significant influence on purchase intention, purchase intention has a positive and significant influence on purchase decisions, purchase intention mediates the relationship between advertising and purchase decisions, and purchase intention mediates the relationship between brand image and purchase decisions.

This study aims to examine the effects of workload, job stress, and work spirit on employee performance at PT Victory International Futures Surabaya, a financial services company operating in the highly demanding futures trading industry. Employing a quantitative descriptive–correlational approach, data were collected using a Likert-scale questionnaire and analyzed through multiple linear regression using JASP and Partial Least Squares–Structural Equation Modeling (PLS-SEM) using WarpPLS, which is suitable for addressing multicollinearity issues and relatively small sample sizes (n = 37). The findings reveal that workload and job stress have significant negative effects on employee performance, whereas work spirit has a significant positive effect and emerges as the most dominant predictor. These results reinforce the Job Demands–Resources (JD–R) theory, which posits that job demands such as workload and stress can reduce performance when not balanced with adequate psychological resources like work spirit. Practically, the study recommends that management optimize workload distribution, implement stress management strategies, and strengthen employee motivation to improve performance sustainably. The study is limited by its small sample size and single-company focus, suggesting that future research should expand the organizational context and incorporate additional variables such as job satisfaction or organizational commitment.

This study examines the psychometric properties of the Indonesian version of the Questionnaire for Eudaimonic Well-Being (QEWB) with a focus on internal structural validity and reliability. The research aims to provide empirical evidence regarding the feasibility of QEWB as an instrument to assess eudaimonic well-being within the Indonesian population. The process involved the adaptation of the original scale, followed by exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) to evaluate its dimensional structure. Findings indicate that the Indonesian QEWB demonstrates adequate internal structural validity and reliable measurement consistency. The four-factor model meaning in life, self-discovery, personal expression enjoyment, and personal satisfaction and fulfillment showed the best fit, confirming the stability of this structure across analyses. Further examination through group comparison suggests that the instrument does not exhibit gender bias within the sample, supporting its fairness and applicability across male and female respondents. These results highlight the potential use of the Indonesian QEWB for research and psychological assessment, particularly in studies focusing on well-being, personal development, and organizational contexts. However, the generalization of findings should be approached with caution due to sample limitations. Future research is recommended to involve more diverse populations and explore additional psychometric evidence to strengthen the scale’s applicability across broader cultural and demographic groups.

Indonesian Sign Language (BISINDO) serves as a primary communication medium for the deaf community; however, limited public understanding often creates barriers during daily interactions. This study aims to develop a real-time BISINDO word-level translation system using hand landmark extraction and temporal modeling with Long Short-Term Memory (LSTM). The system employs MediaPipe Hands to detect 21 hand landmarks per frame, which are then processed as sequential motion patterns to classify five BISINDO words: saya, terima kasih, maaf, nama, and kamu. A total of 250 gesture samples were recorded under controlled lighting conditions as the primary dataset. The processed sequences were used to train the LSTM model, which was subsequently integrated with an ESP32 microcontroller and a DFPlayer Mini module to produce direct audio output. Experimental results show that the model achieved an average accuracy of 86%, with precision and recall values ranging from 0.81 to 0.94. The confusion matrix analysis indicates that most gestures were correctly classified, although some errors occurred in gestures with similar initial motion trajectories. Integration testing demonstrated an average system latency of 3.8 seconds and an audio output success rate of 85%. These findings indicate that the proposed system is capable of translating BISINDO word-level gestures accurately, responsively, and consistently in real-time conditions. This study provides a strong foundation for the broader development of sign language translation systems, with potential enhancements in vocabulary expansion, multi-user datasets, and hardware optimization for deployment in real-world environments.

This study examines the implementation of Project Based Learning (PjBL) in enhancing students’ understanding of moral values in Islamic Religious Education at the tenth grade of MA Yapina. The research is motivated by the urgent need to strengthen character education through learning experiences that are meaningful, contextual, and aligned with the challenges of contemporary moral degradation. Using a descriptive qualitative approach, this study analyzes learning activities, instructional documents, and students’ project outputs to explore how PjBL shapes their comprehension of akhlak as both knowledge and practiced behavior. Findings indicate that PjBL encourages active participation, collaboration, creativity, and reflective thinking, enabling students to interpret moral values through real-life situations and group-based problem solving. Projects assigned to students, such as posters, videos, and thematic presentations, foster deeper understanding because they require the integration of moral concepts into practical tasks. The role of the teacher as a facilitator further supports the learning process by guiding students in inquiry and project management. Despite challenges such as variation in student discipline and time constraints, the overall implementation of PjBL demonstrates positive effects on students’ cognitive and affective grasp of moral values. This study underscores the relevance of PjBL as an innovative pedagogical model for Islamic Religious Education and highlights its potential for strengthening character formation in madrasah settings. It also suggests the need for further research involving direct classroom observations and interviews to enrich empirical evidence on the long-term impact of PjBL on student character development.

This study aims to analyze the effect of the Current Ratio (CR), Return on Assets (ROA), and Debt to Equity Ratio (DER) on Company Value in banking companies listed on the Indonesia Stock Exchange (IDX) during the 2020–2024 period. The research uses a quantitative approach with secondary data obtained from 27 out of 46 banking companies selected through purposive sampling. Data analysis was conducted using panel data regression with Eviews 10, supported by several classical assumption tests including normality, multicollinearity, and heteroscedasticity tests. Further analyses include multiple linear regression, t-tests, F-tests, and the Adjusted R² to evaluate the overall model fit. The partial test results show that the Current Ratio has a significant positive effect on Company Value, indicating that higher liquidity strengthens market perception of firm performance. Meanwhile, Return on Assets does not show a significant effect, suggesting that profitability alone is not a determining factor for firm valuation in the banking sector during the observed period. The Debt to Equity Ratio demonstrates a significant positive effect, implying that investors consider leverage an important indicator in assessing banking performance. Simultaneously, all three variables significantly influence Company Value. These findings highlight the importance of liquidity and leverage in shaping investor appraisal of banking companies in Indonesia.

This research proposes an alternative model for predicting the plasticity potential of clay soils, updating the previous model developed by Firincioglu and H. Bilsel. The alternative lies in the use of the fine fraction content (FC) as the predictive variable, replacing the percentage of sand fraction content (SC) previously suggested. The analysis was conducted on 61 low-plasticity clay (CL) soil samples, classified using the Casagrande and Moreno-Maroto systems, by examining the relationship between consistency limits (LL, PI), grain fractions (sand, silt, clay), and related parameters (FC, sand-silt-clay spectrum, and sand fraction ratio). The correlation analysis results show significant findings, including a strong positive correlation between sand content and the sand ratio (SR), as well as a negative correlation between sand content and FC, and between FC and SR. The performance of the substitute Casagrande quadratic model [2] reveals the best predictive accuracy among the proposed models ( [1], R² =0.90; [3], R²  0.89; [4], R² =0.43; [5], R² =0.93; [6], R² =0.93; [7], R² =0.89; [8], R² =0.89), with the highest R2 value of 0.93, MSE of ≈4.01, and MAE of ≈1.44–1.47.
