Abstract

CV. Citra Buana Mandiri is a used tire recycling or retreading industry, in one month the company is able to produce 800 retreaded tires. The company's production line indicates the occurrence of waste, where one of the concerns is the level of defects produced. The purpose of this research is to identify and minimize waste to improve efficiency in the production line. The method used in this research will be an integration between Lean and Six Sigma. The results of this study show that defects and motion dominate the waste that occurs with a score of 3.60 and 3.0. In addition, the sigma level in the company's production process is at a fairly good level with a value of 3.29. Thus, the suggestions that can be given are related to the evaluation and supervision of SOP implementation and process improvement as well as material and finished product storage.

Abstract

PT. XYZ is a company engaged in the crude palm oil processing sector, one of which is willarine margarine which is exported to various countries. In maintaining global competitiveness, the company strives to produce high-quality products. However, in practice there are still obstacles that need to be overcome. One of them is during the packing process there are three types of product defects identified, namely leakage in the pouch packaging, lack of margarine volume, and damage to the pouch carton. So this research uses the FMEA (Failure Mode and Effect Analysis) method used to determine and transfer the severity, occurrence, and detection levels, so that it is obtained with the highest total RPN, namely leaky pouch packaging of 904, and FTA (Fault Tree Analysis) as a clue with the root of the problem tree, so that it is known that the root causes are lack of rest time, lack of supervision, no concern for the importance of track setting instructions, and no worker concern for cleanliness. After the results are known, improvement proposals are given, namely providing sufficient rest time and always rechecking, providing track setting instructions, and always doing routine cleaning at the beginning and end of work.
