Abstract

The cocoa processing industry plays a strategic role in increasing the added value of agricultural commodities in Indonesia, particularly through cocoa powder production. This study aims to analyze the plant layout and operational processes at PT XY to improve production efficiency using Operation Process Chart (OPC), Activity Relationship Chart (ARC), and line balancing. Data were collected through direct observation, company documentation, and literature review. The results show that the production system is linear, with all activities on the critical path without slack time, and the pressing process as the main bottleneck (approximately 300 kg/hour) limiting capacity. The process-based layout is considered fairly optimal, although integration between quality control (QC) and packaging can be improved. Material efficiency is high (approximately 0.2% loss), while capacity efficiency remains dependent on bottleneck performance.  Keywords: Cocoa agroindustry, plant layout, production line balancing, bottleneck analysis, production efficiency.
