Jurnal Optimasi Sistem Industri (JOSI) has published Vol. 24 No. 2 (2025), released on December 31, 2025. This issue includes 11 articles that address practical industrial and systems problems across operations, human factors, product design, sustainability, and digital adoption.

The articles examine facility layout decisions that account for safety distances and geometric constraints, inbound scheduling for resource-constrained warehouses, and EV route planning that considers charging stops and recharging time. The issue also includes research on human factors in railway maintenance, such as ergonomic risk assessment, what makes people wear hearing protectors, and how to use fNIRS to measure cognitive load. In product and design engineering, the issue includes a study on the design of luxury train seats that integrates emotional perception and local wisdom, as well as a systematic review on flexible FDM 3D-printed insoles for flatfoot treatment. Several papers connect sustainability and digital behavior to industrial outcomes, including consumer responses to greenwashing in single-use plastics, acceptance of food waste mobile applications, and a conceptual model of digitalization and sustainability indicators for SMI resilience. Authors in this issue come from Indonesia, Australia, Germany, Malaysia, the Netherlands, Brazil, Canada, and the United States.
