【 摘 要 】

Industry has an important role in supporting national economy by its contributions to the employment absorption and creating added value of commodities produced. One of the parameters that influence the success of an industry is how the industry evaluates its performance, in particular, the performance of service procurement department. A good industry is an industry which can provide excellent service and well-timed. In the case study, we use pure-birth analysis to evaluate the lead-time procurement in Pupuk Kaltim Inc by collecting the service duration time in each process to be followed in the procurement department and modeling its probability to finish each work at any time. The result shows that the greatest probability of the division to finish their work is around 80 days. Based on the result, we conclude that they have to improve their service performance.
