Upaya Mengurangi Keterlambatan Proses Produksi PT. Aweco Indosteel Perkasa

Abstract

Scheduling is an important thing to determine accuracy on a project delivery to customers. Delays on a project delivery of PT. Aweco Indosteel Perkasa because of in­a­ccurate esti­mated calculation processing time which makes the difference from planned sche­dule with the plan conditions on production. To analyze the causes of delay, used the QCC (Quality Control Ci­rcle) method to get root cause is inaccuracy of estimated cal­c­ulation time jobs and uncontrolled material arrival process. Initial estimated schedule plan for polishing takes 8 shift, while based on the calculation time takes 11.24 shift and on­ the plan conditions takes 17 shift. This indi­cated that there were differences bet­ween plan time, the initial estimate, and the estimate time of calculation. Machine set up makes a difference estimated calculation, whereas the machine set up time very con­sidered in the estimated time calculation of polishing work. Efforts to catego­ri­zing tank types based on components of the tanks was also made. Beside that, calculating time esti­mation in polish machine done for categorizing type of tank.
