Abstract


PT Indofarma Tbk is one of the Indonesian pharmaceutical company that was founded in 1996. One of its products is piroxicam 20 mg capsules manufactured by Production Division I. Production Division I needs to improve productivity by eliminating waste in the production process of piroxicam 20 mg capsule. The cause of waste, based on the method of 5W + 1H, is the waiting time on WIP storage, storage, incorrect process, unnecessary movement, and damage on the piroxicam 20mg capsules. Stages in the research began with the current state mapping (value stream mapping) to identify the existing waste. Subsequently, process activity mapping (PAM) was conducted to describe all production activities. PAM generated value added for 1656 minutes and non-value added for 100331 minutes. Next, the future state mapping was done as a strategy to overcome the waste problem. Improvement of the future state mapping is to create a continuous flow process, work standardization, multi-skilled work, and implement kaizen in the process of charging, polishing, and Packaging sections. The results of future state mapping change the production lead-time of piroxicam 20 mg capsules, from 101959 minutes to 88833 minutes. Changes in the activity of the production process on the future state mapping includes the value added for 1028 minutes and non-value added for 87785 minutes.
