In measure phase, known that the most significant waste in production process of sugar at PT. PG. Krebet Baru were waiting, Inventory and Defect .Based on that fact, this research was very necessary to be executed to understand the causes of wastes and to make an improvement plan by using Lean Six sigma approach and Analysis of Ishikawa diagram.
