Non-dairy creamer is a product made at PT. NDC as a substitute for milk or cream, which is a fat emulsion product. Krimer is packed with a 25kg small bag with an updated coding according to the lot, production time, production date, product name, and packaging date expiration date. Often there is an error in the packaging unit, especially at the coding stage with the wrong non-dairy creamer packaging code that causes packaging defects. The defects in packaging focused on the coding stage, have to be minimized. The research uses the Six Sigma method as a useful tool to increase productivity and product quality. With DMAIC Discussion (Define, Measure, Analyze, Improve, and Control). Through data processing and analysis using the DMAIC cycle obtained three types of packaging defects, namely cryptic code, double code and wrong code from the three defects obtained percentage value of cryptic code 63%, double code 44% and wrong code 42% and obtained an average value sigma 3.71 with a DPMO value of 13,553

One of the process making a creamer is the process of mixing liquid glucose, oil, emulsion powder and water that produces liquid creamer (wet mix / liquid mix). The wet mix results often not match with the standard which can affect the results in the next process. This is the purpose of company to make improvements in controlling wet mix in order to decrease the number of wet mix failure produced. The method used in this research was DMAIC (Define, Measure, Analyze, Improve, Control). Previous data processing was using Seven Tools, with 3 of 7 tools which are the observation sheet (check sheet), pareto diagram, and fishbone diagram. Through data processing and analysis using DMAIC obtained 3 types of failure of semi-finished products (wet mix) which was wet mix as much as 38.8889%, wet mix gross as much as 36.1111%, and wet mix browning 25,0000% and obtained sigma value at Level 3.87. Define is the stage of defining quality problems, and defined the cause. Measure is the stage of measuring the failure rate of the product. Analyze is the stage of quality improvement by analyzing factors causing product failure. Improve is an action plan to improve quality by eliminating factors causing product failure. Control is the last stage of the Six Sigma project that emphasizes the documentation and dissemination of actions that have been done.
