Abstract

This research focuses on the process of producing pins and holes from tenon and mortise machines. Every time the production process, namely 20 sets, experiences a failure of 20%, the characteristics of the failure are a large size between the size of the purus and the wrong hole which does not match the specifications expected by consumers. The company has a target length of the purus and depth of the hole of 30 mm as well as the width of the purus and the width of the hole. 60 mm with a tolerance limit of 2 mm. This research aims to control the process capabilities of tenon and mortise machines. The method used in this research is the IMR control chart to determine the machine process capability value (Cp) and the process capability index value (Cpk). The results of the research show that in the calculation of process capability in the dimensions of shaft length, shaft width, depth of hole and hole, all four do not meet specifications. After analyzing the process capability, the cause of the defect is then searched for using a fishbone diagram, namely creating improvement proposals using the Poka Yoke method. Results of the fishbone diagram: human factors are the dominant factor causing defects. To minimize defects due to human factors, it is necessary to design an ultrasonic distance sensor as a warning function for operators using the Poka Yoke method. The results of applying an ultrasonic distance sensor can increase the process capability value to be in accordance with specifications.

Abstract

This study aims to find out (1) differences in student learning outcomes in the application of blended learning model flipped classroom type with enriched virtual learning model (2) more effective learning model between blended learning model flipped classroom type and enriched virtual learning model. The research method used is a quantitative quasi-experimental design by using pretest-posttest control. The population in this study is all students of grade X majoring in Accounting and Finance of SMK Negeri 3 Surakarta Institution. The sample used in this study was 72 students. Sampling techniques in this research are by total sampling method. Data obtained from pre-test and post-test results based on indicators of student learning outcomes. The results obtained from this study are as follows. First, there are differences in learning outcomes in Digital Simulation subjects in experimental classes by applying flipped classroom type blended learning models and control classes by applying enriched virtual learning models. Evidence from the average study results of experimental classes of 82.94 and control classes of 75.39. Second, flipped classroom blended learning models are more effective than enriched virtual learning models. The effectiveness of applying flipped classroom type blended learning models in experimental classes is in a moderate category, while the effectiveness of implementing enriched virtual learning models in control classes is in a low category.
