Polypropylene plastic products. Kusuma Mulia Plasindo Infitex . This study uses the seven tools method. The seven tools method uses 7 quality control tools, namely Check Sheets, Control Charts, Cause and Effect Diagrams, Pareto Diagrams, Histograms, Scatter Diagrams and Flowcharts. From the results of research using the seven tools method, it can be seen that the causes of defects in Polypropylene plastic products are caused by 4 aspects, namely machine factors caused by age and machine maintenance, materials that are not according to standards, human factors caused by lack of training and factors of workers' methods that are not according to SOP/standard operating procedures.

The purpose of this research is to use a clustering algorithm on learning outcomes, gender, and SRL. In this study, the K-Means clustering method was used. In this study, the calculation process is assisted by Orange software. Determination of the number of clusters with Orange software based on the Silhouette Score. The results show that there are seven clusters with three variables, namely learning outcomes, gender, and self-regulated learning. From these clusters, it can be used for group formation and student mapping.
