Abstract

PT. Charoen Pokphand Indonesia Feedmill is one of the largest animal feed companies in Indonesia. One of the obstacles experienced by PT. Charoen Pokphand Indonesia Feedmill Balaraja is the downtime due to the replacement of the (sifter change) sieve fabric that is on the pellet machine 7. The frequency of downtime caused by the replacement (sifter change) of this sieve cloth occurs 2-3 times in 1 month. The method used to solve and analyze downtime problems is to use DMAIC with the five why's Analyze tool. There are several factors that cause downtime because the fabric is not strong vibration sieve, the fabric is too tight, and blacu material is not durable. Proposed improvements made is to install verloop and change the installation method of the sieve fabric. The result of the improvement is reduced the frequency of downtime to 2 times in 2 months and reduce waste cost. The Results of the implementation will be compared in the last 2 months, February and March 2018, company achieve cost savings Rp. 194.645.793,00 in terms of pellet, while in terms of packging Rp. 193.208.052,00.

Abstract

PT XYZ is a manufacturing company engaged in the manufacture of heat exchangers. PT XYZ has a make to order demand fulfillment strategy with large product variations. The existing production process at the company consists of several lines, one of which is the SS-CS line. SS-CS line has a bottleneck in one of the processes, which is welding process. The welding process itself is done by welder and welding preparation operator. The number of welders and welding preparation operators is considered unbalanced, causing a bottleneck in the welding process. The purpose of this research is to find the optimal number of welder and welding preparation operator so that the welding process no longer having bottleneck. The optimal number of welder through calculation result and simulation is 16 people while operator welding preparation is 7 people. The output produced with the optimal number of workers can reach more than 2 times the original condition. The average utility of both types of workers is over 90% and is almost balanced with a 5.98% difference. By implementing this proposal, the company can save Rp. 504,523.90 per month in terms of not needing anymore overtime costs that have been issued and the salary addition of workers to be issued.

Activities carried out for repairs are preparation activities, color actions, blower settings, and printing area positioning. Improvement efforts made by the author are the use of a colorimeter, torque wrench, the use of a special box for setup equipment, and the application of a maintenance blower. Control of proposed improvements is by making tool use guidelines and a checklist for the blower maintenance schedule. Implementation cannot be done because there is no setup schedule. The making of proposal has been discussed with the head of production who understands the machine setup in detail. The proposal is believed to reduce the changeover time because it has answered the root cause of each setup activity.
