The government’s physical distancing policy to prevent transmission of the covid19 virus caused changes in learning patterns from face-to-face learning to distance education. The application of distance education at Universitas Negeri Yogyakarta is one of them through e-learning. Measurement of the level of e-learning user satisfaction is an assessment of the success of e-learning itself. The method used to measure students’ level of satisfaction using e-learning is End-User Computing Satisfaction (EUCS). EUCS has five indicators, namely, Content, Accuracy, Format, Ease of Use, and Timelines. The research sample was taken using a random sampling technique. The data collection technique was carried out using a questionnaire. Data analysis uses descriptive statistical analysis and inferential statistical analysis. Based on the analysis results, the content evaluation value is 4.0300, the accuracy evaluation value is 4.0200, the evaluation value is 4.2550, the evaluation value for easy use is 4.0288, and the evaluation value for timeliness is 4.0900. The overall analysis results showed that the students were satisfied with the e-learning course in vocational learning media.

There are obstacles in the delivery of information during pre-engineering activities at the Vocational High School. There needs to be a system that makes it easy to deliver information from schools to students who carry out internship. The purpose of this study was to evaluate the usefulness of the evaluation of the usefulness of the task information learning system and the monitoring of student labor based on the SMS gateway with raspberry pi. The instrument used in usability testing is the Computer Usability Satisfaction Questionnaires: Psychometric Evaluation and Instructions for Use questionnaire developed by IBM for software usability measurement standards. The instrument for testing usability aspects with the Computer System Usability Questionnaires (CSUQ) questionnaire developed by IBM uses a Likert scale as a measurement scale. The data for the trial were 20 respondents consisting of adaptive normative subject teachers, internal engineering committee and smartschool developers. Based on the results of testing the quality of software developed on the usability aspect has a percentage of 85% or has a high quality scale and based on alpha cronbach calculations has a calculation result of 0.851 or has a “good” category. The SMS Gateway system with Raspberry Pi for Internship Assignment and Monitoring meets the usability aspect and is suitable for use.

This study aims to develop a product in the form of a tungsten inert gas (TIG) welding practice manual for Class XII students and find out the level of the eligibility. This research is a type of Research and Development (R&D) research. The stages of this research include problem identification, data collection, product design, design validation, design revision, limited trial, product revision I, large group trial, product revision 2, product ready to use. Data collection techniques are done using a questionnaire. The data obtained were analyzed using quantitative descriptive analysis techniques. The results of this study are in the form of a TIG welding practice manual for class XII students. The feasibility level of the TIG welding practice manual is known through the validation process carried out by 4 expert validators. The feasibility test was conducted on 30 students. The average feasibility value obtained from experts as well as the feasibility test on students was 84.81% and included in the very feasible category.

The development process of augmented reality generally requires devices and software with high compatibility so that they are the only obstacles in its development. The purpose of this study was to design and produce an application of learning media on the hydraulic cylinder of excavator based on augmented reality with Shapr3d for prospective students of automotive engineering education and to see the product feasibility level of the test subjects and validators. This learning media development stage consists of five stages: Analysis, Design, Development, Implementation, and Evaluation. For the data method using direct observation and closed questionnaires. The questionnaire of the research results was analysed using Likert scale analysis. The results of the material expert validator with a score of 91.25% are very good category. Expert media design validator 92.5% is included in the very good category with a very proper name. The response to product use from three lecturers of automotive engineering education with a proportion score of 88.34% is in the very good category. The response to the use of the product was from twenty automotive engineering education students with a score proportion of 85.73% in the very good category. This that the application of automatic learning media on excavator hydraulic cylinder based on augmented reality with shapr3d based on Augmented Reality technology that has been developed can be used in elementary schools as a learning media for technical education.
