Abstract

PT Sinergi Mitra Lestari Indonesi is a company engaged in the management and distribution of mining products, particularly tin and ferronickel. In its business operations, the company relies on warehouse performance as a central hub for controlling the flow of goods and information. This study seeks to identify and empirically analyze how warehouse capability, inventory management, and human resource competence contribute to the effectiveness of tin and ferronickel warehouse management at PT Sinergi Mitra Lestari Indonesia. Furthermore, the study explores how the effectiveness of warehouse management impacts the optimization of the company’s supply chain. Employing a quantitative approach, data were collected through questionnaires distributed to 229 respondents consisting of the warehouse staff, logistics personnel, and management level. This data is subsequently analyzed using the SEM-PLS method to analyze both direct and indirect relationships among variables. Furthermore, supply chain optimization significantly mediates the relationships between these independent variables and warehouse management outcomes, emphasizing its crucial role in translating operational capabilities into performance improvements. Among the predictors, warehouse capability demonstrates the strongest total effect on management effectiveness, highlighting the importance of infrastructure and technological support in logistics operations. This shows that PT Sinergi Mitra Lestari Indonesia must enhance warehouse efficiency, optimize space utilization, and strengthen supply chain processes to remain competitive in the mining sector.

Abstract

In the fast-moving consumer goods (FMCG) industry, the return of products to the warehouse is often an unplanned occurrence with an uncertain quantity, but the academic research on this is still not as advanced as the practice. Previous research is contradictory about the effect of return volume uncertainty, return information quality, and return decision quality on the operational performance of a warehouse, and the link between those variables through the reverse process effectiveness is not yet conclusively proven, particularly in the FMCG warehouse in Indonesia. In this study, return volume uncertainty, return information quality and return decision quality are directly and indirectly tested for their impacts on warehouse operational performance, while the reverse process effectiveness acts as a mediator. The data was obtained from 138 employees, supervisors, and managers in warehouses at FMCG companies in Indonesia based on cross-sectional survey analysis using the method of Partial Least Squares (PLS) Structural Equation Modeling. Return information quality had a direct impact on warehouse operational performance, whereas return volume uncertainty and return decision quality only had indirect implications when they had an impact on reverse process effectiveness. The novelty here is to demonstrate that the effectiveness of reverse process can serve as the hinge on which the benefits of information quality, decision quality and volume-uncertainty management can become tangible in the warehouse.
