Abstract

This study aims to analyze the blood supply inventory control at the Blood Transfusion Unit (UTD) of PMI of Malang city, in response to its suboptimal management. Data shows that there were 15 stockouts and 19 overstocks during the 34-month period from January 2022 to October 2024. This study incorporates the deterministic Economic Order Quantity (EOQ) method, combined with safety stock and reorder point methods. All of which were performed to optimize the blood supply inventory control and to minimize the total inventory cost for all blood types-A, B, O and AB. The Holt’s exponential smoothing was applied to the data pattern indicate certain identifiable trends. The result of the calculations predict the optimal quantity of blood bags for each resupply period, the optimal safety stock, and the optimal reorder point for each blood type. Further, the EOQ method was found to be able to cut the total inventory cost by more than 50% each year for every blood type.

Abstract

This paper aims to identify the functional, symbolic, hedonic and Islamic value constructs of Muslim consumers’ satisfaction with fine dining restaurants. In addition, it develops the role of religiosity in the relationship between hedonic and Islamic symbolic values ​​in consumer satisfaction and examines the effect of such satisfaction on the willingness to pay more. The method used in the research is based on a Structural Equation Modeling (SEM), with data collected using a questionnaire; 281 valid respondents took part in the study. The results show that in terms of the influence of the dimensions of perceived value in explaining customer satisfaction, the functional, hedonic and Islamic have has a positive and significant effect, whereas the symbolic value variable is is perceived to have no significant effect on satisfaction. Furthermore, customer satisfaction has a significant positive effect on the willingness to pay more. In comparison, religiosity does not moderate the effect of perceived symbolic value on consumer satisfaction. However, it does moderate the effect of hedonic and Islamic value.
