Industry 4.0 drives supply chain digitalization to enhance operational efficiency. This study analyzes the impact of Digital Supply Chain (DSC) implementation on achieving production targets in a shortening oil company. A quantitative approach with descriptive analysis was used to measure efficiency improvements. Data were collected through observations, interviews, questionnaires, and documentation. The results show that DSC increased operational efficiency by 17%, reduced production downtime by 66.67%, and increased production capacity from 4,650 kg/hour to 5,738 kg/hour. Additionally, DSC contributed to reducing raw material waste and improving production target achievement by 14.76%. Statistical analysis confirmed that DSC significantly affects production efficiency, contributing 80%. This study recommends better system integration and workforce training to maximize DSC benefits.
