Crankshafts are the most important loaded components in the case of an automobile. In order to achieve required mechanical properties most of crankshafts for automobile are forged with micro alloyed steel. Usually, the shapes of crankshafts are complex, and many defects are induced during the process of crankshaft forging such as under-filling, laps and folds etc. In this work the forging analy...

Clusters are geographically close groups of related companies or institutions related to a certain area which are inherently more efficient than the other companies due to advantages such as being located in one place, networks, external knowledge, variability of human capital, etc. Today, development through clusters plays a pivotal role in the economic and industrial policies of developed...

PT Prima Kemasindo always strives to maintain the quality of its products, especially product. However, there are still products do not meet standards set company. This because company has used definite method monitor control limits for level damage. Thus, this study aims d...

UD. Utomo Joyo has problems related to monthly production defects, where the company a maximum defect target of 5% total for one period, but defects that occur exceed estimates. This study aims find solutions improve application Statistical Quality Control method quality sarong products at using Seven Tools (7 QC), namely flowcharts, checksheets, histograms, control charts, pareto diagrams, sca...

The most important issue in multi-objective optimization problems is to determine the Pareto points along the Pareto frontier. If the optimization problem involves multiple conflicting objectives, the results obtained from the Pareto-optimality will have the trade-off solutions that shaping the Pareto frontier. Each of these solutions lies at the boundary of the Pareto frontier, such that the i...

The Plywood company in this study was able to produce 6,000m3/ year of plywood, but during 2018 and 2019 only provide 2,905.14 m3/year 1,120.73 m3/year. Production is far below the production capacity. This research will apply lean manufacturing concept process a plywood company. uses value stream mapping (VSM), analysis tools (VALSAT), activity (PAM), Pareto diagrams, root cause analysis. It f...

Abstract In early project stages, often no simulation results are available for dividing‐wall columns. Hence, shortcut methods used to estimate suitable vapor and liquid splits. a previous paper, it was demonstrated that diagrams suited tool satisfy this need. However, has turned out shows weaknesses columns with finite or non‐optimal stages. This contribution closes gap presents an extended ap...
