Abstract

Research aims to analyze the application of Six Sigma in order to support the improvement of fabrication process capabilities. The improvement of fabrication process capability is expected to have an impact on the overall reduction in production and logistics costs, which we called a supply chain costs. A case study at a fabrication company was carried out to calculate the capability of the fabrication process and make improvements by applying the Six Sigma method. In this case, product quality that produced from the fabrication process largely determines the supply chain costs incurred by the company. Minitab software is also used in processing and analyzing data. This research shows that improving the fabrication process capability has an impact on reducing product defects so that supply chain costs are lower. Research provides an illustration for the industry that continuous improvement with the aim of reducing the occurrence of product defects will not only have an impact on reducing production costs, but also on logistics costs. As the Six Sigma method implemented, the number of defective products has decreased from 8 pcs per 100 pcs Collar products to 0 pc from 100 pcs Collar products. Fabrication process capability of PT BMT reaches Cpk 5.94 with the sigma value 6 Sigma. The implementation of the Six Sigma method also has a positive impact on overall supply chain costs, with a reduction in supply chain costs of 7.6%. So that PT BMT has a fabrication process that is more effective and efficient.

Abstract

One of the important supply chains that supply raw materials for edible oils is the production system. Influencing costs that can be minimized by preventing overstocking of raw materials. The purpose of this activity is to explain the importance of supply chain inventory planning in food ingredients and to estimate demand using forecasting techniques, i.e. production planning using Autoregressive Integrated Moving Average (ARIMA) and Material Requirements Planning (MRP). to carry out the plan. Method based on Fixed Order Quantity (FOQ) and Periodic Order Quantity (POQ). This activity is targeted at food distributors, and it is expected that the effectiveness and efficiency of food distribution activities will be enhanced by applying these two methods. The socialization method is conducted through webinars (online seminars) with presentations of materials and questions and answers. There were 104 seminar participants, consisting of employees from various production and logistics institutions and 4 ITL Trisakti lecturers. According to the evaluation questionnaire after the exchange meeting, the seminar participants were satisfied and interested in the activities of her ITL Trisakti Lecturer. The results of this socialization activity will be very useful for the training of industry participants, especially those working in the food sector.
