Abstract

This study aims to analyze the effects of e-Procurement efficiency, regulatory compliance, and supervision on transportation subcontractor performance, as well as to examine the mediating role of transportation subcontract governance at PT Pos Indonesia (Persero). A quantitative approach was employed using Structural Equation Modeling with Partial Least Squares (PLS-SEM) to test both direct and indirect relationships among variables. Data were collected through a census survey of 120 respondents from hub offices directly involved in managing and supervising transportation subcontractors. The results indicate that e-Procurement efficiency and supervision have a positive and significant effect on transportation subcontractor performance, while regulatory compliance does not have a direct effect on performance. However, regulatory compliance (β=0.512, p<0.001) and supervision (β=0.343, p<0.001) significantly influence transportation subcontract governance, which in turn positively and significantly affects subcontractor performance (β=0.320, p=0.002). Furthermore, subcontract governance mediates the effects of regulatory compliance (β=0.164, p=0.009) and supervision (β=0.110, p=0.013) on performance, but does not mediate the effect of e-Procurement efficiency. These findings suggest that strong governance mechanisms are critical in translating regulatory and supervisory efforts into improved subcontractor performance.

Abstract

This study examines the effects of packaging, digital information, and crowd logistics on distribution performance and their implications for last-mile delivery among food and beverage SMEs utilizing online transportation services in Bandung, Indonesia. The rapid growth of digital-based delivery services has increased operational complexity in urban logistics, particularly regarding delivery accuracy, timeliness, and distribution effectiveness. A quantitative explanatory approach was employed using survey data collected from 131 SMEs selected through probability sampling. Data were analyzed using Structural Equation Modeling–Partial Least Squares (SEM-PLS) with SmartPLS. The findings reveal that packaging, digital information, and crowd logistics positively and significantly affect both distribution and last-mile delivery. In addition, distribution has a positive and significant effect on last-mile delivery performance. Mediation analysis further confirms that distribution partially mediates the relationships between packaging, digital information, crowd logistics, and last-mile delivery. These findings indicate that effective distribution systems strengthen the influence of operational, physical, and digital factors on final delivery performance. This study contributes to the logistics and supply chain literature by proposing an integrative framework that simultaneously combines packaging, digital information, and crowd-based logistics dimensions within a unified last-mile delivery model for online transportation-based SMEs.
