In a manufacturing company, a production process is one thing that is very concerned. In a production process, there are activities that are classified as activities that do not add value to the product. This is called a non-value added activity. Therefore, analysis and improvement can help to reduce waste contained in the production process of making TWD-DHT-K002 products. The method used to analyze the existence of non-value added activities is value stream mapping. This method can help to map the actual production flow and can help classify activities that are value added and non-value added. The result of this research is a time comparison of value added, non-value added from before and after the proposal. The results obtained can be seen from the difference in Manufacturing Cycle Efficiency (MCE). MCE before the proposal was 0.40% while after the proposal was 0.41%. Then for the results of the comparison of the percentage before and after the proposed value added and non-value added on the TWD line, the value added increased by 7.82%. Non-value added decreased by 6.63% while for necessary non-value added decreased by 1.19%. While on line A3 for value added it increases by 1.52% and necessary non-value added decreases by 1.52%.

PT.X is a company engaged in the manufacturing of heat exchangers. PT.X has a standard time formula for each process on the production floor. The washing process formula currently only uses three variables from the specifications of each unit. The research carried out at PT.X aims to see whether the standard washing process standard time formula is still relevant or not to be used today. Observation data shows that the average time of 105.88% of the results of the calculation formula is greater than the actual time. The results of the calculation of the new formula are designed to approach the actual time and only use two of the seven factors that significantly influence the washing process time based on the ANOVA test results. The new standard time formula was built using a regression model. Standardizing the washing process using a new formula can reduce the washing process production costs by 39.8% from € 0.1008 / minute to € 0.0607 / minute.
