Analisis Pengendalian Kualitas dalam Upaya Meminimalisasi Tingkat Kerusakan Produk Gula Rafinasi

Abstract

ABSTRACT  Non-conformance to products is produced due to unavoidable production processes. However, it can be minimized in terms of potential occurrences as well as providing a solution to achieve a minimum level of mismatch. This study aims to identify the percentages and types of discrepancy experienced by the company, analyzing process capabilities and identify underlying factors in discrepancy. The research has been done in May 2018. The reseach was implemented in lab and department of process at PT Sugar Labinta, Tanjung Sari, Lampung Selatan. The use of the six sigma method with a structured DMAIC approach is definie, measure, analyze, improve, and control. The tools used in six sigma program on this research consisted of check sheet, caused diagram, p-control chart, and Pareto diagram. It’s processed through the software Minitab 18. The results showed the level sigma process in PT Sugar Labinta 5.04 and has a value DPMO 238.32 based on the table of achievement Sigma defined that the company is at the average level of the USA industri, then to be able to reach the level of Sigma 6 , the discrepancy in respect of the product does not exceed 8 tonnes per month.
