Facility layout efficiency is pivotal for the operational performance of PT Lembur Hejo’s hydroponic agribusiness. This study evaluates the effectiveness of the existing layout to identify workflow inefficiencies using a descriptive quantitative approach. Utilizing the Activity Relationship Chart (ARC) and Total Closeness Rating (TCR), functional relationships were mapped and prioritized. The results stratified facilities into three clusters: core production (TCR 176) as the highest priority, followed by employee support (TCR 80), and administrative facilities. While the analysis validated the efficiency of the production zone, it revealed a significant spatial dissonance regarding support facilities (office, dormitory, restrooms), which are currently misaligned with their functional priorities. Conclusively, this study demonstrates the efficacy of ARC/TCR in detecting latent inefficiencies beyond the core production area.
