This research has a purpose to determine the effect of online transaction security on purchasing decisions through the Shopee application. The respondents consisted of 74 students from the Digital Business Study Program at Universitas Amikom Purwokerto who actively use Shopee. This research employed a quantitative descriptive method with simple linear regression analysis. The results indicate that online transaction security has a positive and significant effect on purchasing decisions, with a regression coefficient of 0.887 and a significance value of 0.000. The coefficient of determination of 35.2% shows that transaction security contributes to purchasing decisions, while the remaining percentage is influenced by other factors. The higher the level of security perceived by consumers during online transactions, the greater the likelihood of making a purchase. These findings highlight the importance of improving security systems and information transparency on e-commerce platforms such as Shopee to create a safe, comfortable, and trustworthy shopping experience for users.

This study aims to analyze and determine the optimal production capacity at Sekar Arum MSMEs to achieve maximum profit using the Linear Programming (LP) graphical approach. The research employed a quantitative method with a descriptive approach. The data used included primary data from interviews and observations, and secondary data from production and raw material records. The analysis was conducted by formulating a mathematical LP model consisting of an objective function and constraint functions based on the limited resources available to the enterprise. Data processing was carried out using POM-QM for Windows version 5 with the graphical method to identify the optimal solution point. The results indicate that the optimal production combination is 2 kilograms of red ginger and 3 kilograms of tamarind turmeric, yielding a maximum profit of Rp4,600,000 per production cycle. The implementation of Linear Programming proved effective in assisting MSME owners in making efficient production decisions, thereby enhancing profitability and the sustainable use of resources.

This study aims to analyze the influence of work discipline, work motivation, and incentive provision on employee performance in the production department of PT Wonojati Wijoyo. The study employed an associative quantitative approach, with 65 respondents selected using a purposive sampling technique. Data were collected through a five-point Likert-scale questionnaire that passed validity and reliability tests. The data were analyzed using multiple linear regression with SPSS version 29, including classical assumption tests, t-test, F-test, and the coefficient of determination (R²). The results show that work discipline has a positive and significant effect on employee performance, while work motivation and incentive provision have no significant effect. However, simultaneously, the three variables significantly affect employee performance, with a coefficient of determination of 77.9%, indicating that the remaining 22.1% is influenced by other factors not included in the model. These findings highlight the importance of implementing human resource management policies that balance discipline, reward systems, and motivation programs to improve employee performance sustainably.

This study aims to analyze the influence of emotional intelligence, work discipline, and job commitment on employee productivity at DP3AP2KB Kota Kediri. The research employed a quantitative approach with a population of 45 employees, all of whom were included as the sample using a saturated sampling technique. The research instrument was a five-point Likert-scale questionnaire tested for validity and reliability. Data were analyzed using multiple linear regression with the aid of SPSS version 25, preceded by validity, reliability, and classical assumption tests (normality, multicollinearity, and heteroscedasticity). The results indicate that emotional intelligence has a significant partial effect on employee productivity, while work discipline and job commitment show no significant effect. However, simultaneously, the three independent variables significantly affect productivity with an Adjusted R² value of 0.846. These findings highlight that emotional intelligence is the dominant factor influencing productivity, whereas work discipline and job commitment function more as basic requirements already embedded within bureaucratic systems. The practical implication of this study suggests the need for soft skill development programs, emotional management training, and the improvement of employees’ interpersonal skills to enhance productivity in the public sector.

This study aims to analyze the influence of financial literacy, self-control, parental influence, peer influence, and income on students’ saving behavior in the Economic Education Study Program at Universitas PGRI Ronggolawe Tuban for the 2021–2024 cohort. A quantitative approach with an associative research design was applied. The population consisted of 173 students, and the sample was determined using Slovin’s formula with a total of 64 respondents. Data were collected through a Likert-scale questionnaire and analyzed using multiple linear regression with the assistance of SPSS, including classical assumption tests. The results reveal that financial literacy, parental influence, and income have a significant positive effect on saving behavior, while self-control and peer influence have a significant negative effect. The coefficient of determination (R²) is 0.724, indicating that 72.4% of the variation in students’ saving behavior can be explained by the independent variables, while the remaining 27.6% is influenced by other factors outside the model. These findings highlight that students’ saving behavior is shaped by the interplay of cognitive, psychological, social, and economic factors.

This study aims to analyze the effect of training and human resource development on employee performance at the Social Service Office of Bima City. The research was motivated by the low level of employee productivity, limited budget allocation for development programs, and the tendency of some employees to delay task completion. The study employs a quantitative approach with an associative method. The population consists of 59 employees, with a sample of 35 civil servants selected through purposive sampling. Data were collected using questionnaires, observation, interviews, and documentation. The analysis techniques include validity and reliability tests, classical assumption tests, multiple linear regression, t-test, and F-test. The findings show that both training and human resource development have a significant and positive impact on employee performance. Training improves employee skills, while development efforts enhance competencies to meet organizational demands. The study suggests that structured training and development programs should be optimized to improve public service performance.

This study aims to optimize sales profit at the MSME Batagor Bandung Tarakan by applying the Simplex method in linear programming, supported by the POM-QM for Windows software. Profit optimization plays a crucial role in strategic decision-making, particularly in determining the optimal daily production quantities to enhance operational efficiency, maximize the use of raw materials, and meet market demand effectively. The Simplex method was chosen for its ability to solve linear optimization problems involving multiple constraints and variables, providing accurate mathematical solutions to achieve maximum profit. This research utilizes daily production data as the basis for analysis, which is then processed using the Simplex method in POM-QM. The results show that implementing the Simplex method can increase daily profits from IDR 634,000 to IDR 831,408 through a more efficient production combination. The study concludes that the Simplex method, when applied via the POM-QM software, is an effective tool for daily production decision-making and can support MSMEs like Batagor Bandung Tarakan in improving their competitiveness and business sustainability.
