Abstract

COVID-19 became a pandemic that occurred in many countries around the world including Indonesia. On April 4, 2021, confirmed positive cases in Indonesia were recorded at 1,534,255 cases. West Java occupies the highest position recorded on April 10, 2021 amounting to 256,834 cases until July 3, 2021 positive cases have reached 2,228,938 positive cases of Covid-19 virus. Various ways have been done by the government to reduce the growth rate and spread of the Covid-19 virus, one of which is the provision of vaccines to the community. Distribution of vaccines needs to be done as quickly as possible, so an appropriate distribution strategy is needed. This study aims to determine the location of the Covid-19 vaccine distribution center in West Java. The method used in determining the location point of the vaccine distribution center is the Center of Gravity method. Based on the calculations obtained the coordinate point of the location of the Covid-19 vaccine distribution center in West Java is -6.83041 and 107.73030 with a total distribution cost of Rp31,939,000. The location of the vaccine distribution center provides a greater cost value compared to the cost in the initial condition of Rp 30,091,000. In terms of distance, the location of the latest distribution center resulted in a smaller distance of 3055.3 km compared to the initial condition with a total distance of 3389.8 km. The distance produced by the distribution center is shorter so that it will increase the efficiency of delivery time which will make the distribution process faster

Abstract

PT. XYZ is one of the pharmaceutical companies that always make continuous improvements. Based on observations at the company, there is a decrease in the performance of the Washing Vial machine used for the washing and sterilization process of the vial. This problem causes a large number of rejected products so that production targets are not achieved. This study aims to calculate the OEE (Overall Equipment Effectiveness) and Six Big Losses values of gilowy machines so that they can be known the largest losses incurred by the machine. Based on calculations obtained OEE (Overall Equipment Effectiveness) value of 53.68% with Availability of 63.36%, Performance Ratio of 87.21% and Quality Ratio of 97.59%. The calculation of the Six Big Losses is equipment failure loss of 36.64%, Setup Time Losses of 17.07%, Reduced Speed Losses of 8.36%, Idle and Minor Stoppage of 40.25%, Defect Losses of 1.36% and Reduced Yield Loss of 0%. From these results show Idle and Minor Stoppage to be the biggest factor losses that occur in the Gilowy machine
