Abstract

Supermarkets and food retail outlets are essential for contemporary society to meet its demands. To spur competition among business people to expand their operations, businesses are developing from small scale to large scale along with the times. In the supermarket business, implementing good inventory management can have a significant impact on purchasing efficiency. This research aims to examine the effect of inventory management strategies on purchasing efficiency at PT Ratu Idaman Pratama. The population in this study were all employees of PT Ratu Idaman Pratama, while the research sample was 20 people who held staff positions or above. Inventory management is a process of arranging, managing and controlling the amount of goods or materials owned by a company so that they are always available when needed without excesses that can cause additional costs. Meanwhile, purchasing efficiency is the ability to obtain the goods or services needed with good quality and the best price, with minimal time and resources and as economically as possible. Data analysis in this paper uses data quality tests, classical assumption tests, simple linear regression, hypothesis testing, and coefficient of determination. The research results prove that inventory management variables simultaneously have a significant effect on purchasing efficiency. The coefficient of determination value is 0.174. This means that 17.4% of the dependent variable can be explained by the independent variable, namely Inventory Management. It is hoped that from the results of this research, the leadership of PT Ratu Idaman Pratama will always supervise inventory management so that it can increase purchasing efficiency. 

Review

This study investigates the critical role of inventory management in enhancing purchasing efficiency within the context of supermarkets and food retail, specifically focusing on PT Ratu Idaman Pratama. The research addresses a pertinent topic, given the competitive nature of the retail industry and the ongoing need for businesses to optimize operations. The authors clearly define their core constructs: inventory management as the process of arranging, managing, and controlling goods to ensure availability without excess, and purchasing efficiency as the ability to acquire necessary goods or services with good quality, best price, and minimal resources. The stated aim is to examine the effect of inventory management strategies on purchasing efficiency, providing a focused inquiry into a practical business challenge. The methodology employed is quantitative, utilizing a survey approach with a sample of 20 employees holding staff positions or above at the target company. While the use of data quality tests, classical assumption tests, and simple linear regression is standard for this type of analysis, the sample size of 20 participants is notably small. This limitation could impact the statistical power and generalizability of the findings beyond this specific instance. The key finding indicates a statistically significant effect of inventory management on purchasing efficiency. However, the reported coefficient of determination ($R^2$) of 0.174 suggests that inventory management explains only 17.4% of the variance in purchasing efficiency. While significant, this value implies that a substantial portion (over 82%) of purchasing efficiency is influenced by other unexamined factors, which warrants further consideration and exploration. In conclusion, this paper offers a foundational insight into the relationship between inventory management and purchasing efficiency at PT Ratu Idaman Pratama, providing a direct, actionable recommendation for the company's leadership to prioritize inventory supervision. While the study's focus on a single company and its limited sample size restrict the broader applicability of its findings, it lays the groundwork for further research. Future studies could benefit from expanding the sample size, incorporating multiple organizations to enhance generalizability, and exploring other variables that contribute to the significant unexplained variance in purchasing efficiency. Additionally, a deeper dive into specific inventory management strategies and their differential impacts, perhaps using a mixed-methods approach, could offer richer insights into how businesses can more effectively leverage inventory practices for operational gain.
