| dc.description.abstract | Although it has been supported by various kinds of modern facilities in a production system, PT Toyota Motor Manufacturing Indonesia (TMMIN) still face problems in material management system. Fluctuations in unit cost per vehicle produced from Toso Shop in each month are one of the problems faced by PT TMMIN. In addition, there are also differences between the monthly reports of the item budget control with the actual use of some materials. Hence, it is necessary to analyze the situation in order to improve the accuracy of the material management system. TBP are measures used by Toyota in solving a problem in an effective and focused way. TBP consists of 8 stages: Problem Clarification, Breakdown Analysis, Target Setting, Root Cause Analysis, Countermeasure, See Countermeasure Through, Evaluation, and Standardization. Based on the number of steps to analyze the problems of accuracy, it is known that the material that has the lowest accuracy is F1 material (pigment) with 69.45% accuracy level. This caused bycheck sheet filling that are not orderly carried out. The solution of theproblem is by making new check sheet and developing Standard Operating Procedure’sfor sheet filling. The changes in the new check sheet is related with some additional explanation in the form of information-time option, the symbol A-Z, formula calculation, Bulk filling column, the column totals and summary columns in a month. | en |
