Abstract

PT Djambi Waras Jujuhan is a company engaged in the production of crumb rubber. During the production process there is still waste or waste, namely defect, waiting and transportation. To reduce waste, a lean manufacturing approach is carried out, so that it is known the causes of waste on the production floor with VALSAT, and provides suggestions for improvements with FMEA. Based on the results of the study, it is known that the causes of waiting are sluggish workers, inaccurate, trouble in the engine, only forklift 1, and uncertain weather. The cause of the defect is the lack of accuracy, fatigue, creeper diameter shrinking, blunt creeper rool, improper knife settings, improper temperature regulation, dirty raw material, thick blanket, high raw material moisture content, and rain. The cause of transportation is that the work procedure is not carried out properly, the worker is only 1, and the forklift is only 1. From FMEA it is known that the RPN value of each waste is waiting for 294, the defect is 252, and transportation is 36. To reduce waste is recommended to reduce energy work, admonishing workers who do not comply with regulations, choosing workers who have good skills in accordance with their fields of work, increasing control actors, improving work methods, and adding transportation equipment.

Abstract

This research is motivated by the low enthusiasm and participation of students in social studies learning which is considered boring due to the lack of facilities and less varied learning methods. The purpose of this study was to determine the influence and magnitude of the influence of the Example Non Examples learning model on improving the argumentation skills of grade VIII students at SMP Negeri 3 Srengat. This study used a quantitative approach with a Quasi Experimental Nonequivalent Control Group design. The research sample consisted of 30 control class students and 27 experimental class students selected through purposive sampling techniques. Data were collected through questionnaires and learning outcome tests, then analyzed using the Independent Sample T-Test and Effect Size tests. The results showed that there was a significant influence of the Example Non Examples learning model on improving students' argumentation skills, with a significance value of 0.000 <0.05. Cohen's d test showed a value of 6.140 which indicated a large influence. These findings indicate that the Example Non Examples model is effective in improving students' argumentation skills in social studies subjects, so it can be used as an alternative learning model to create more active and meaningful learning.
