Abstract

Employee performance in airport service support environments faces distinctive challenges due to high discipline requirements and intensive operational pressures, while empirical studies focusing specifically on discipline and motivation within airport support services remain limited. A quantitative approach was employed using a saturated sampling technique involving 60 employees from the Facility Care (K2) Department of PT Angkasa Pura Support. Data were collected through Likert-scale questionnaires and analyzed using multiple linear regression with classical assumption testing. The findings indicate that work discipline has a positive and significant effect on employee performance, while work motivation also contributes significantly. Simultaneously, both variables moderately explain variations in employee performance, highlighting the importance of combining internal motivational factors with adherence to structured work systems in airport service contexts. These results reinforce human resource management theories and provide contextual contributions to high-risk service sectors. Practical implications emphasize the need to strengthen discipline systems through effective supervision and to enhance motivation through reward mechanisms and organizational support in order to achieve sustainable performance improvement.

Abstract

This research examines the influence of financial self-efficacy and impulsive buying on risky credit behavior among housewives who use Shopee PayLater in the Jomin Estate housing complex. A quantitative descriptive–verificative design was applied with 136 respondents. Data were analyzed using multiple linear regression via SPSS version 26. The findings indicate that financial self-efficacy exerts a positive and significant effect on risky credit behavior, suggesting that greater confidence in financial management may increase engagement with higher-risk digital credit. Impulsive buying also shows a positive and significant effect, implying that unplanned purchasing intensifies credit risk. Jointly, both variables explain 59.6% of the variance in risky credit behavior. These results underscore the role of psychological and consumer behavior factors and provide empirical insights into Buy Now Pay Later usage, informing efforts to promote more responsible digital credit management.

Abstract

The objective of this study is to analyze the differences in the results of Cost of Goods Sold (COGS) calculations using the full costing, variable costing, and job order costing methods, as well as to determine the most efficient method for improving the effectiveness of production cost management. The research method used is a descriptive comparative quantitative study, with the subject being the SME Ahyusni Aqiqah & Catering for the period 2023–2025. Data were collected through observation, interviews, and documentation, then analyzed using the three methods and the results were compared. The research findings indicate that the full costing method yields a higher and relatively stable COGS because it includes all production costs. The variable costing method yields the lowest COGS because it includes only variable costs. Meanwhile, the job order costing method shows fluctuating results due to periods without production, which cause fixed costs to accumulate and be charged to the following period. The conclusion of this study is that the choice of COGS calculation method significantly affects the cost per portion, so it must be aligned with managerial objectives and business characteristics. Consequently, the Job Order Costing method is more suitable for order-based SMEs, full costing is better suited for long-term pricing, and variable costing is appropriate for short-term cost control.
