IMPROVEMENT OF WORK ACTIVITIES TO REDUCE ANTASIDE PRODUCTION PROCESS TIME USING LEAN MANUFACTURING PRINCIPLES AS AN EFFORT DURING THE COVID-19 PANDEMIC
During the current Covid-19 pandemic, a faster supply process is needed, especially such as medicines that are needed and urgently needed. Antacids as Stomach Acid Drugs are one example, because Chronic Stomach Acid Disease can worsen the condition of Covid-19 patients. PT. Lucas Djaja is a manufacturing industry company in the current production conditions, there are indications of waste that causes the production process to be less efficient. The purpose of this study is to identify waste that occurs in the production line. The method used to map the activity process in order to identify the occurrence of waste is to use Value Stream Mapping, which in this mapping is divided into two, namely Current Stream Mapping and Future Stream Mapping. In the Current Stream Mapping is made to describe the current flow of material, then Value Stream Analysis is carried out by weighting activities that are not value added. It was found that there were four activities including waste, namely waiting for the Work in Process to cool down, waiting for the Coding Etiquette and Carbox process, waiting for work order documents and rework on bottle caps. After this, improvements are made with Root Cause Analysis to identify the root cause of the waste. Then use 5w + 1h to get the proposed improvement. After the proposed improvement is obtained, then a mapping is carried out with Future Stream Mapping to provide an idea if the waste can be eliminated. So that the Antacid production process time can run according to the expected processing time and become more efficient than before. The production process time that has been saved is 48 minutes 14 seconds.
