Currently the industry is trying to improve its competitiveness. This makes the manufacturingindustry needs to adapt the Lean-Kaizen concept. Lean-Kaizen means eliminating waste through small improvements made on an ongoing basis. This research takes a case study at PT Inoac Poltechno Indonesia, which is engaged in foam production. The current production target is only 56% of the planned target. Besides that, there are found many defective products and activities that have no added value. Furthermore, a map of the current condition is made to find waste and know the kaizen that will be carried out. Furthermore, a future map was developed with work standardization and Value Stream Mapping to determine activities that have no added value. Calculation of Waste Assessment Model (WAM), shows the biggest waste is defect (26.73%), inventory (15.79%), and waiting (13.35%). This study found that by adding trolley, adding operators, making SOPs, scheduling engine maintenance would make non-value added (NVA) activities decrease from 29.95% to 20.5%. Process Cycle Efficiency increased from 22.31% to 28.25% (thus fulfilling international PCE requirements for the manufacturing industry). Keyword : Lean-Kaizen, productivity, waste

Value stream mapping has the reputation of uncovering waste in manufacturing, production and business process. This helps in identifying and removing or streaming value added steps and eliminating non value added steps. In this study the process was analyzed to find an opportunity to drastically reduce the number of actions and to simplify the same. By reducing waste the proportion of value adding time increases in the whole process and the process throughput speed could also be increased. This makes the redesigned process more effective and more efficient. The reengineered process was flow charted in its future state with process steps and information flows re-engineering, simplified and economized. The current layout was analysed to identify and eliminate the non value added activities through lean tools like 5S, VSM and line balancing in a manufacturing industry. From the observed results, it was concluded that the non value added time could be reduced by about 13% while the process cycle efficiency could be increased by about 10%. Virtual simulation was conducted to verify and validate the existing situation as well as to propose the results and the effectiveness of lean principles in a systematic manner with the help of ARENA.

The manufacturing industry is increasingly accountable for the environmental impact resulting from its activities. Research indicates that specific production processes within manufacturing plants generate significant environmental impact through energy consumption. To understand the consumption of energy in a production environment, it is necessary to outline the energy flow within the facility, along with the classification of energy usage and its relationship to processes and production outputs. It is also important to identify auxiliary (non-value added) energy within production as the area with the greatest potential for savings through changes in operational behaviour. This article introduces a practical process mapping methodology that combines energy management with value stream mapping. The methodology is based on ‘Lean’ manufacturing principles and on application to a couple of industry use cases has been shown to successfully illustrate the relationship between the energy usage and production activities for a particular value stream. Furthermore, the significant energy users in relation to the actual production process steps have been identified, and energy reduction opportunities of 42% and 50% have been quantified.
