Abstract

The layout of the factory is the main foundation in the industrial world, in this study there are problems in the production process of doll houses where most of the workers are persons with disabilities. At the production station, there is a long distance between the material work station, which results in an increase in transfer costs and the amount of production output produced. The method used in this study is a flow diagram and map of the operation process. This method is used to determine the flow of the production process from the beginning of the raw material to the process of checking the finished product. This study uses ARC to be able to find out the relationship of each work station and find out the reasons for each work station. The flow of the production process of doll houses in the company still needs to be improved. Because between a work station and other work stations it is not regular according to the flow of the production process. Based on the results of research on dollhouse production it was found that the amount of transportation between each work station and warehouse resulted in wasteful production time. It was concluded that there is a critical path, namely the path of the Raw warehouse to the cuttting machine. There is a flow that is too long/far, namely cutting machine to Pattern, pattern path to Jigsaw 1, and the Jigsaw path to Forging.

Abstract

A systematic literature review is a rigorous method of assessing and combining research results compared to the usual literature review, which consists of annotated bibliographies, a systematic review of the existing literature regarding specific research questions on a topic of interest. Statistical Process Control (SPC) is a well-established technique in a context that has recently been used in software production. Software production is not like manufacturing because it requires more human resources and machines, resulting in an item's one-time production. It is therefore essential to assess what SPC works in a software context. Thus, this consideration has motivated us to define and conduct an evaluation review to assess whether SPC is used effectively and genuinely Quality Control Cycle (QCC) in Indonesia's various industries. According to a systematic literature review process, an established protocol was revised and refined by the authors. This journal collection of journals has been used in various industries in Indonesia. We report our preliminary considerations and results in a systematic review on the SPC and find 30 journals collected as references for readers in making research journals related to SPC. Our products and first impressions are favorable. This journal collection can also make it easier for researchers to get the desired journal references.

Abstract

This research shows that we all have realized the need for clean air and globally have regulated exhaust emissions from air pollution, so electric vehicles have emerged. But this phenomenon has an impact on belt companies that supply parts for CVT gasoline-powered automatic scooters because the majority of electric motors no longer need a belt as a drive transfer from the engine to the wheel. Simulated with a dynamic model for the projection of the next 20 years from 2019 to 2039, with two scenarios, namely COVID-19 and if the government's policy target of 20% of the motorbike market switches to electricity in 2025, then gradually increases to 30% in 2035. PT XYZ as a belt supplier with an 85% market share in Indonesia, will get a net profit of 50% if this scenario is achieved until 2039 became around 131 billion per year, previously with the no-scenario model it was projected to get a net profit of around 221 billion. Maybe if the demand for electric motorbikes is more than what the government has targeted, it is likely that the two-wheeled automotive belt business could be threatened in the next 15 - 20 years. Meanwhile, the largest Expense is the cost of imported materials, reaching 65% of the total cost of Expenses consisting of Salary Expenses (Salary Expense), total training costs, cost of sales, total loss costs, material costs, and Operating overhead Recommendations that business can survive, companies can reduce material costs by developing local materials, and help shape the automotive belt use ecosystem by working with automotive manufacturers.
