Facility layout efficiency is a key factor in supporting sustainable waste bank management. This study aims to optimize the facility layout of the Resik Babakan Sari Waste Bank in Bandung City using a Systematic Layout Planning (SLP) approach and the BLOCPLAN algorithm. The research methods include observation, interviews, and process analysis using Value Stream Mapping (VSM) and Process Activity Mapping (PAM) to identify value-added (VA) and non-value-added (NVA) activities. Data on material handling frequency, space requirements, and closeness relationships between facilities were processed using BLOCPLAN software to generate more efficient layout alternatives. The results show that the total material handling distance is reduced from 204.5 meters to 127.48 meters, representing a 37.7% reduction. This improvement enhances material flow efficiency, reduces internal transportation time, and improves operator safety and comfort. Therefore, the integration of SLP and BLOCPLAN is effective in producing a more efficient, ergonomic, and sustainable facility layout.
