Abstract

Harapan Mulya Putri is a manufacturing company established in 2010. This company produces equipment for cleaning or cleaning tools, hotel equipment, restaurant equipment, household equipment, and traffic signs. Problems encountered by Harapan Mulya Putri company that the number of stainless steel trash backorders will reach 28% in 3 months. This study aims to reduce the number of back orders in the production process of stainless steel trash bins. Reducing the number of back orders is done by designing a simulation model of stainless steel trash bin production. The method used is a dynamic system simulation. Three scenarios are used to maximize the fulfillment of consumer demand. The first scenario is a policy of adding raw materials suppliers send, such as 150 units of stainless steel plates. The simulation results for the first scenario resulted in a 75% decrease in back orders. The second scenario is ordering based on the bill of material grouping to optimize raw material utilization. The simulation results of the second scenario reduced back orders by 56.25%. The third policy scenario is combined with the first and second scenarios. The results of the third simulation show that back orders have decreased by 87.5%. Thus, the selected scenario is the third scenario.

Abstract

XC Clenaindo Company is a manufacturing company that provides cleaning and sanitation services in Indonesia. However, defects that exceeded the company's tolerance limits were found in hand sterilizer products. This research aims to improve product quality so that it satisfies customer needs. Analysis was conducted to determine the leading causes of product defects using the Six Sigma Define, Measure, Explore, Design, and Implement (DMEDI) method. The DMEDI Six Sigma method is a quality improvement method with a creative approach so that the resulting solution can be a new work system design. The results of the defined process research found two problems, namely product defects because the Sterobac hand sterilizer bottle was convex and the length of the label installation process. At the measure stage, it was discovered that the problem was in the filling and labeling process, which was influenced by the increasing number of requests. At the exploration stage using the 5 why deep interview method, it was discovered that the problem was due to the lack of temperature during the liquid pouring process and the label design making the sticking process difficult. So, the work process was redesigned at the filling stage, and a new label design was created, which made it easier for workers to stick labels and apply the 5S concept. The final stage was implemented by designing the Poka-Yoke Form and Worker Operational Standards for the Filling. This research results in a reduction in the number of defective products.
