The retail industry is currently facing increasingly intense competition, requiring optimal supply chain efficiency. Warehouses play a strategic role in controlling inventory flows and supporting a company’s operational performance. At K3Mart, stock shortages are still frequently found, caused by low supplier compliance with Service Level Agreements (SLA) and delays in delivery schedules, which negatively affect distribution processes and store service quality. This study aims to analyze the effect of supplier compliance with SLA and delivery timeliness on warehouse operational performance at K3Mart. This research employs a quantitative method by distributing questionnaires to 40 respondents from the warehouse, purchasing, and procurement divisions using a saturated sampling technique. The research instrument uses a Likert scale. Data analysis was conducted using validity and reliability tests, classical assumption tests, multiple linear regression analysis, t-test, F-test, and coefficient of determination with the assistance of SPSS software. The results show that supplier compliance with SLA and delivery timeliness have a positive and significant effect, both partially and simultaneously, on warehouse operational performance. Therefore, improving supplier compliance with SLA and delivery timeliness can enhance optimal warehouse operational performance.

This study aims to determine the influence of independent variables, namely Promotion, Location, and Product Variation, on the dependent variable, Purchase Decision, at Seduhlur Coffee Kediri. The research method used is quantitative, employing multiple linear regression analysis with the assistance of SPSS version 26 software. The sampling technique applied in this study is incidental sampling, which involves selecting respondents who happen to be present and meet certain criteria at the time the research is conducted. Based on the results of data analysis, it can be concluded that the Promotion variable has a positive and significant partial effect on Purchase Decision. This indicates that the better the promotional strategies carried out, the more likely consumers are to make a purchase. Similarly, the Location variable also shows a positive and significant partial influence, suggesting that the comfort and accessibility of Seduhlur Coffee’s location play an important role in influencing consumer decisions. Product Variation is also found to have a positive and significant partial effect on Purchase Decision, meaning that a greater variety of products offered increases the likelihood of attracting consumer interest. Simultaneously, all three variables — Promotion, Location, and Product Variation — have a significant and positive influence on Purchase Decision. This research is expected to provide useful input for Seduhlur Coffee Kediri in improving its marketing strategies and service quality to encourage and increase consumer purchasing decisions.
