Abstract

This study aims to explore the implementation of vocational learning in the new normal era related to the content, assignment forms, class management, and describe teacher innovations and hope. The research was conducted using a quantitative descriptive approach with a research instrument is a questionnaire. The questionnaire was given to 46 respondents consisting of mechanical engineering vocational teachers from several regions in Indonesia. The questionnaire consists of two categories, namely statements with an option and statements with open answers. The findings of this study are based on two categories, namely theoretical and practical learning. The results reveal that in theory learning, teachers prefer to share material with students in various forms, including PDF, PPT, Video, and others (17.56%), assigning forms in summarizing material (25.19%), and with the full class (47.78%). In contrast, in practical learning, the teacher conducted learning with a system block (5.85%), gave assignments in the form of making projects or products (6.93%), and with half-class management combined with online classes (7.78%). Another finding is the innovation applied by teachers is developing technology-based learning materials and using online platforms. In the new era's learning situation, normal teachers expect a flexible curriculum, as well as standardized, effective, and efficient media, models, methods, and learning platforms. In the learning practice, the teacher expects practice videos and simulation applications that are expected to be by following the expected basic competencies and being equipped with learning practices with the application of health protocols and students' numbers.

Abstract

Currently, plastic is more dominantly used because it is cheap, elastic and easy to process. To maintain the quality of plastic products, especially the type of Polyethylene Terephthalate (PET), the researchers implemented a modern plastic manufacturing system, namely using an injection molding system. In order to be able to meet the demands in solving problems that may arise in the process of making plastic products such as: quality, manufacturing time, and safety systems. The injection molding method replaces the old method, namely the hand press machine. This selection is based on advantages such as the consistency of the product produced because it is programmed, equipped with a control system, shorter product time, adequate security system, and other advantages. In this research, an experiment will be conducted to determine the optimum cooling temperature in the form of Pet Gallon. The problems that often occur are product defects due to shrinkage. In connection with this, the test results are obtained as follows: there is a difference in the shrinkage of product dimensions in the experiment using Cooled Chiller and Tower Chiller cooling, cooling has the greatest influence on the processing time of product manufacture, the optimum cooling temperature occurs at a cooling temperature of 200C.
