Abstract

PT. X is a dairy industry located in East Java province. PT. X has implemented lean manufacture since 2015. Lean manufacture is a continuous process, so it needs to be followed by an evaluation or assessment process of lean implementation. For that, it is very important for PT. X to conduct a lean assessment, because so far it has never been implemented. In addition, the need to conduct lean assessment is also driven by the Overall Equipment Effectiveness (OEE) value of PT. X which only reaches 40% to 60% where the company's target is 75%. This suggests that a process improvement is needed where a lean assessment can identify areas that need improvement. Lean assessment is done by modifying the lean assessment tool from previous research which is quantitative approach. From the qualitative lean assessment results with the aggregate scoring method and quantitative with the fuzzy logic method, it is known that the order of the dimensions with the worst to best Leannes values is time effectiveness, cost, inventory, delivery, quality, process, human resources, customer. The dimension of time effectiveness as a critical dimension with the lowest Leannes value, which is 0.677, is the focus for root cause analysis using 5 whys method. Each root cause of the problem identified from each indicator has made recommendations for improvement plans based on the level of effectiveness and difficulty as well as the priority scale. By compiling an improvement plan such as create a preventive maintenance program outside of production time and arrange standard procedures related to troubleshooting & problem solving, it is expected that after implementation it will increase the ability to implement lean manufacturing and the company's OEE value.
