Abstract

Indonesia's exports of jewellery trends that continue to rise are not in line with the increase in Production Output Trends from companies in Indonesia’s industri. This research uses one of jewellery manufacturing company in Bali province as a case study. This research used a Six Sigma DMAIC (Define-Measure-Analyze-Improve-Control) method which the objective is to improve productivity through integrated DMAIC phase of a project. On the Define phase, this research used a SIPOC (Supplier-Input-Process-Output-Customer) Diagram. On the following Measure phase, a questionnaire used to collect primary data and company data for the secondary data. The questionnaires obtained from 4 Experts in Continuous Improvement and 5 Experts in Jewellery Manufacturing Industry. On the Analyze phase, a combination of Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS)-Analytic Hierarchy Process (AHP), and Decision Tree are used to be able to see a result from different approach. Lastly, at the Improve and Control phases, a Perfomance Indicator approach were used. The obtained result from this research, are the most important Productivity Factor for a jewellery manufacturing company which is Labor Producitvity with the ranked order of 9 alternatives based on Ideal Solution on the increase of productivity. The chosen alternative with the highest priority ratio is the Implementation of the daily activity planning system for all employees, with an estimated increase in productivity at the level of 47%. To support the success of alternatif implementation Overall Worker Efficiency (OWE) performance indicator were being proposed.
