Abstract

The research was conducted to identify the root cause of rejects on spin on products in the assembly process of PT. XYZ. It aims to determine the right improvement to reduce the reject rate on spin on products. This study applies the pareto chart and cause effect diagram to describe and determine the root cause of the problem. The proposed improvement is to apply a damper to the shutter. The results of implementation improvement bear positive result and reduce the project rate. Results before improvement are worth 0.19%, and after improvement worth 0.13%.

Wellgan begins with a decision (Gap Analysis) between the requirements of the ISO 9001: 2015 QMS and the fulfillment of the documents which PT. Wellgan has and the implementation of the company. The results of the initial gap analysis were 61.97%, still requiring fulfillment of ISO 9001:2015 requirements by making documents which are required by ISO 9001: 2015. QMS. The design and manufacturing of documents are document control, design and development, inappropriate product control, Audit Internal and management meetings.

Abstract

The DMAIC method is used to solve problems that exist in PT. X in terms of the quality of feed produced. The DMAIC method can identify the highest type of disability by using pareto charts, knowing the root of the problem using fishbone diagrams and knowing the solutions that can be implemented to minimize the occurrence of defective products using FMEA. The results of the study that the highest type of disability is abnormal texture consisting of streaks, high flour and pellet escapes. The root problem of the disability is the pelletizing process and the sieving process. The proposed improvement is to modify the engine and provide coaching to the operator to be more routine in maintaining cleanliness and checking the engine elements used for the production process.
