Abstract

This research aim to develop an improvement plan of GTR 2 pump production process at CV. Guntur Malang by incorporating Lean Six Sigma approach. Following DMAIC steps (Define-Measure-Analyse- Improve-Control), at Measure stage shows that the most affecting waste is waiting and defect . Next at Improve stage using 5 W – 1 H method resulted on improvement plan consist of (a) applying statistical based quality control system by developing control chart during GTR 2 pump test process, (b) additional training to operator, review and correct work instruction, (c) relocate material warehouse from Research and Development area and material stock pile rearrangement, and (d) applying coolent to material before drilling process.

Abstract

PT. Gading Mas Indah Malang represent one of LPG distributor which has a handling of inefficient distribution problem in delivery process to agent where less gives attention to demand, no definite scheduling and route make the high of distribution cost. Periodic Vehicle Routing Problem (PVRP) is a route planning from a depot to consumer among m-day period. In this research, PVRP used to optimize visit frequency and route of each agent to minimize distribution cost. The first step is clustering agents by k-means approach then determining delivery quantity, formulate mathematical model of PVRP, and solution searching using LINGO software to select the route which gives the minimum cost. From the result, optimum visit frequency is 1 visit and transportation cost saving is Rp 733,500,-/week equal to 40.82%.
