Abstract

PT. KHI Pipe Industries is a manufacturing company specialized in the production pipeline. In the process of pipe production in PT. KHI one of them using a machine SPM 2000 which produces spiral pipes with a size of 53 meters and production activities more than on production activities on other machines frequent occurrence of resistance or activities that do not add value. The purpose of this study was to 1. Knowing third largest waste that occurs in the production of spiral pipe in SPM 2000 2. Increase the percentage value Proces Cycle Efficiency (PCE) and Manufacturing Cycle Effectiveness (MCE) before and after the recommendations and provide suggestions for process improvement spiral pipe production. The methods used to cope with lean manufacturing waste, namely that of which there are seven kinds of waste is overproduction, waste transportation, waiting, over waste processing, inventory, motion waste, and the waste product defect. After the identification of the seven waste, and then perform the mapping to find the right tools to use Value Stream Analysis Tools (VALSAT). Based on the calculation of the percentage obtained workshop waste waste that occurs is waiting 20%, processing over 16.19%, 15.24% transportation, defect 14.29%, 12.38% inventory, motion and overproduction 11.43% 10.48% with a lead time of 445 minutes and tilapia percentage of PCE and MCE 61%. To reduce the lead time that happens needs to be designed improvements by using the tools Process Activity Mapping, Value Stream Mapping and Root Cause Analysis to see the roots of permasalahaan occur. After that then made PCE and MCE future with a percentage of 73% Katakunci : Lean Manufacturing, Proces Cycle Efficiency (PCE), Manufacturing Cycle Effectiveness (MCE),Root Cause Analysis (RCA)
