Abstract

Crystal guava contains many nutrients such as vitamins B and A, as well as antioxidants that are good for health, such as boosting the immune system, aiding digestion, improving skin health, and reducing the risk of heart disease. Conducting a cost analysis is an important step that must be taken by business operators. The purpose of this study is to assist crystal guava farmers in Bantarsari in achieving fair profits through an analysis of the Production Cost Analysis for Crystal Guava Fruit in Bantarsari Village, aiming to determine the appropriate and competitive selling price for this business. Production Cost Analysis can be conducted using either the Full Costing or Variable Costing method. In this study, the Full Costing method was used, where the researcher included all production costs, such as fixed costs and variable costs, in the COGS calculation analysis. From the analysis conducted, the COGS was determined to be Rp 3,173 per kilogram, meaning that this price is the minimum selling price that can be applied for the business to reach the break-even point, where income and expenses are balanced

Abstract

This research seeks to measure the financial ratio trends of PT. Indonesia Kendaraan Terminal Tbk from 2015 to 2023. The analysis employs a horizontal approach, which involves comparing the company's financial statements across different years and evaluating them through various financial ratios, such as liquidity, solvency, profitability, and activity ratios. The type of research used is quantitative descriptive research. The data used is secondary data sourced from the official website of the Indonesia Stock Exchange, www.idx.co.id, and primary data from the company's official website, www.indonesiacarterminal.co.id. The data collection methods used are documentation and literature study. Based on the research findings, the liquidity ratio indicates that the company is capable of meeting short-term obligations using current asset or available cash and cash equivalents. The solvency and profitability ratios saw a downturn during the COVID-19 pandemic but have since progressively improved, approaching their pre-pandemic levels. However, in general, both ratios still tend to indicate a declining performance. The activity ratio remains in a relatively good condition, despite the figures appearing relatively small.

Abstract

This study investigates the influence of safety knowledge and safety management practices on safety performance, with safety motivation as a mediating variable, at PT. Shinko Plantech. The research aims to understand how workers’ awareness and implementation of safety procedures contribute to overall safety outcomes in the workplace, and to what extent motivation affects this relationship. A quantitative approach was employed using a survey method. Data were collected from 120 employees through a structured questionnaire and analyzed using Structural Equation Modeling (SEM) with the help of SmartPLS software. The findings reveal that both safety knowledge and safety management practices have a significant positive effect on safety performance. Furthermore, safety motivation was found to mediate the relationship between the independent variables (safety knowledge and safety management practices) and the dependent variable (safety performance). These results highlight the critical role of fostering not only strong safety practices and knowledge but also enhancing employee motivation to achieve optimal safety performance. The study contributes to occupational safety literature and provides practical implications for improving safety standards in industrial settings.

Abstract

MSMEs must adapt to globalization and competition, with human resources being crucial for profitability. In Kupang City, MSME actors struggle with competitive strategies, innovation, and collaboration due to low education and skills. This study investigates the impact of human capital on market orientation and performance among 99 MSME actors, using stratified random sampling and Partial Least Squares (PLS) analysis. Results indicate that human capital significantly influences market orientation (49.5% correlation) and MSME performance (path coefficient of 0.228, t-statistic of 2.518, p-value = 0.012). Market orientation also positively affects performance (path coefficient of 0.438, t-statistic of 4.465, p-value = 0.000). The model shows good predictability (R-squared of 0.245 for market orientation and 0.343 for performance). The study concludes that enhancing human capital and adopting effective market orientation strategies are vital for MSME performance improvement, providing empirical support for the literature on these factors in developing countries like Kupang City

Abstract

As international trade increases, so too does the risk involved. Therefore, good risk management is necessary to minimize the risks that arise. One way to do this is through hedging. This study aims to examine the impact of leverage, growth opportunity, firm size, profitability, and liquidity on hedging decisions in processing industry companies, which include two sectors: consumer cyclical and non-cyclical. The sample of this study was 30 companies listed on the IDX (idx.co.id) for the period 2020-2024. This study utilizes panel data comprising 150 observations, employing the binary logit estimation method, where the dependent variable is a dummy variable. This study provides an empirical contribution that reveals the relationship between financial factors (leverage, growth opportunity, firm size, liquidity, and profitability) on hedging decisions. The findings provide evidence that firm size and liquidity are dominant predictors of hedging decisions, with negative results, while other factors such as leverage, growth opportunity, and profitability do not affect hedging decisions, so that the results of this study can provide a new picture for companies in designing a more measurable hedging strategy and with this companies should focus more on managing their firm size and liquidity.

Abstract

Mental workload is the gap between the requirements of a task and a person's highest achievable capacity when working under motivated conditions. At PT. XYZ, the high production demands have resulted in significant overtime hours for employees. In one of the production buildings, employees are reported to work overtime almost daily. According to overtime records, individual employees experience up to 143 hours of overtime per month. This study investigates the mental workload of production line employees using the NASA-TLX questionnaire, followed by a cause-and-effect analysis. The NASA-TLX assessment classified all operators as experiencing high levels of mental workload. These findings were further analyzed through a cause-and-effect diagram, which revealed that high mental workload levels were influenced by human factors, equipment, methods, and the working environment.

Abstract

The purpose of this study was to analyze the extent to which influencer marketing and electronic word of mouth (E-WOM) simultaneously influence consumer purchasing decisions. This research employed a quantitative approach with a survey method. Data were collected through questionnaires distributed to 100 respondents who had purchased or used cosmetic products after being exposed to influencer marketing and E-WOM, selected using purposive sampling. Data analysis was conducted using multiple linear regression to determine the influence of the independent variables (influencer marketing and E-WOM) on the dependent variable (purchase decision). The findings reveal that influencer marketing and E-WOM significantly affect consumer purchasing decisions, with a combined contribution of 56.9%. This result highlights the novelty of integrating both digital strategies as complementary drivers of consumer behavior in the cosmetic industry, particularly in an era where peer-to-peer communication and digital endorsements increasingly shape purchase intentions. From an academic perspective, this study enriches the literature on digital marketing by demonstrating how the synergy between influencer credibility and electronic word-of-mouth creates a stronger explanatory framework for understanding purchasing decisions. Practically, the findings imply that cosmetic brands should not only optimize influencer collaborations but also design strategies that stimulate authentic consumer engagement to enhance E-WOM, thereby achieving a sustainable competitive advantage in digital marketplaces.

Abstract

This study tried to look into how digital marketing interactions affect things on Generation Z consumer loyalty towards local beauty products in Indonesia. Regarding the digital transformation, Generation Z exhibits a strong tendency to engage actively in interactive communication with brands. This research adopted a quantitative explanatory approach using a survey methodology. Data were collected from 120 respondents aged 18–27 years who had used local beauty products within the last six months and were digitally active. The research instrument consisted of closed-ended questionnaires measured on a five-point Likert scale. Validity and reliability tests confirmed that the instrument met the required statistical standards. Tests of classical assumptions, encompassing normality, multicollinearity, and  hetero-scedasticity, also confirmed that the regression model was statistically valid. A simple linear regression analysis revealed that digital marketing interaction significantly and positively influenced consumer loyalty, The regression coefficient is 0. 532, and the significance level is 0. 000. The R Square value is 0. 521, which means that 52. 1% of the variation in consumer loyalty is explained by the model. The findings highlight the strategic importance of enhancing interactive digital marketing to foster emotional bonds and long-term loyalty among Generation Z consumers. This research adds value to existing knowledge by emphasizing interaction quality over mere digital presence

Abstract

This study investigated the impact of integrating digital technology into Syariah-based Islamic education on student learning outcomes and social cohesion in ten madrasahs across Banda Aceh, a region that the 2005 Helsinki Peace Accord has shaped following decades of conflict. Employing a sequential explanatory mixed-methods design, the research combined survey data from 500 students with qualitative interviews and focus group discussions involving educators, students, and religious leaders. Digital tools—such as Islamic e-learning platforms, interactive da’wah applications, and multimedia Qur’an modules—were examined for their influence on academic engagement, critical thinking, and intergroup harmony. Quantitative analysis revealed significant positive relationships between technology-enhanced instruction and student motivation, critical reflection, and civic responsibility. Structural Equation Modeling (SEM) showed that student engagement partially mediated the relationship between digital pedagogy and social cohesion (total effect ? = 0.68, p < .001). Thematic analysis indicated that technology reinforced Islamic learning, promoted inclusivity, and gained wider acceptance when framed within Syariah values and supported by local ulama. The findings suggest that, when thoughtfully implemented, digital Islamic education can act as a peacebuilding mechanism. Recommendations include teacher training, institutional investment, involvement of ulama, and long-term evaluation for sustainability and replication
