Abstract

One of the main raw materials in the production of uyel crackers at Raya I Factory is tapioca flour. Based on most previous studies, the EOQ method has a function to analyze the inventory of raw materials in the warehouse, including for determining the economic order quantity and also optimizing costs. July to September 2024 is the time for conducting research at Raya I Cracker Factory located in Manisrenggo District, Kediri City. This study analyzed three variables, namely the need for the quantity of tapioca flour raw materials, ordering costs and storage costs. The results of the EOQ method-based study obtained that this business should determine the most economical single order quantity at a volume of 46,188 kg for inventory management in the period October 2023 to September 2024. During this period, Raya I Cracker Factory experienced a decrease in inventory management costs of Rp. 46,212,246.

Abstract

Purpose-This study investigates the effects of employee creative self-efficacy and flexible human resource practices on organizational resilience, with employee job engagement as a mediating variable. While previous studies on organizational resilience have mainly focused on structural and policy-based factors, this research extends the literature by emphasizing the role of individual psychological resources in building resilience within organizations. Methodology-This study employed a quantitative survey design involving 131 employees of logistics companies in the Yogyakarta, Indonesia, selected through purposive sampling. Data were analyzed using partial least squares–structural equation modeling to examine direct and indirect relationships among employee creative self-efficacy, flexible human resource practices, employee job engagement, and organizational resilience. Findings-The results demonstrate that employee creative self-efficacy has a positive and significant effect on both employee job engagement and organizational resilience. Employee job engagement also significantly enhances organizational resilience and serves as a mediating mechanism between creative self-efficacy and resilience. In contrast, flexible human resource practices show no significant direct or indirect effect on organizational resilience, indicating that formal human resource flexibility alone is insufficient to foster resilience without active employee engagement. Research Limitations-This study is limited by its cross-sectional design and reliance on self-reported measures, which may introduce common method bias. Additionally, the focus on a single industry and regional context may constrain the generalizability of the findings. Novelty-This study contributes novel insights by demonstrating that organizational resilience is driven more strongly by individual psychological resources than by formal human resource flexibility. It further identifies employee job engagement as the critical mechanism that transforms creative self-efficacy into organizational adaptive capacity. By revealing the limited role of flexible human resource practices in the absence of employee engagement, this research challenges prevailing structural-centric resilience models and offers a micro-foundational perspective on resilience in high-pressure service environments.
