The Just-In-Time (JIT) system has long been a foundation of production efficiency in the global automotive manufacturing industry. However, the semiconductor crisis that struck the world in 2020 to 2023 presented a serious test of the resilience of this zero-buffer inventory-based production system. This study aims to analyze the resilience of the JIT system at PT Toyota Motor Manufacturing Indonesia (TMMIN) in facing supply chain disruptions caused by the global semiconductor shortage. Using a qualitative descriptive approach based on a single case study, this research utilizes secondary data from TMMIN Sustainability Reports 2022 and 2023, GAIKINDO production statistics, global industry reports, and verified academic literature. The results show that despite the semiconductor crisis impacting TMMIN production capacity, the company maintained operational continuity through three main adaptation strategies: production model prioritization, component stock optimization, and strengthened industry ecosystem coordination. These findings support the argument that JIT does not need to be abandoned, but rather evolved into an Adaptive-JIT model that integrates resilience mechanisms without sacrificing long-term Lean efficiency principles.
