The use of technology is very important in learning in the pandemic era. Various efforts were made to equip teachers to optimize the use of learning media. One of these efforts is to organize training on making interactive quizzes based on information technology which is held at SMP Negeri 1 Jaten. This training aims to provide insight related to learning media so that teachers are able to improve their abilities in making interactive quizzes and have a good impact on the future learning process. The method used in this training consists of three stages, namely preparation, implementation and evaluation.This training was conducted on May 6 – May 7, 2021 and was attended by 32 teachers for grades VII, VIII and IX consisting of subject teachers. The result of this training activity is that the teacher understands the training material well so that all the information obtained can be directly put into practice. Teachers get material that is very relevant to the needs in the classroom and can support learning activities. In addition, teachers get new insights related to learning media that can be applied in preparing interactive quizzes creatively and innovatively.
The design of analog electronics learning media applications needs quality analysis. ISO 25010 is one of the standard references in measuring the quality of an Android-based application product. Analysis that can be done is by testing the compatibility and performance efficiency aspect of the media being developed. This study uses a Research and Development (R&D) method with the ADDIE development model which will produced a quality analog electronics learning media application. Data collection was conducted used a cloud testing and direct testing. Before data collection was conducted validity of media by expert judgement. The results showed that media is "valid" and the quality of the compatibility aspect this media learning was supported on more than 208 smartphones android device and performance efficiency predicate “Satisfied” so that the application could be used for the learning process during the COVID-19 pandemic or tested on other quality aspects.
This study aims to develop Electrical Machine Training Kit for electrical machine practice media in vocational education. This type of research with Analyze, Design, Development, Implementation, and Evaluation (ADDIE) model. The background of this research is that the need for electrical machine competency, which students should have mastered, is still insufficient due to inadequate tools. Many graduates still have difficulty getting a job in the industry because competence has not been fulfilled during college. Electronic engineering vocational education is a study program that has the goal of producing superior graduates in achieve electrical machine competence and being ready to work in the industry. Electronic engineering vocational education is a new study program that is still in the development stage to achieve this goal. The media aspect obtains a minimum value of 87.5% and a maximum value of 90%. Material aspects get a value of 88.40% for suitability material and 90.2% for the quality of learning. The user feasibility test obtained a value of 89.80% in review from motivation, 88.0% in terms of convenience, and 90.3% in terms of material. It is concluded that the Electrical Machine Training Kit is included in the "very feasible" category.
The unemployment rate for vocational high school graduates is still very high. Unemployment occurs because the level of work readiness is still low. Work readiness can be improved by applying competence mastery-oriented learning. Competence that is complete requires measurement tools or assessment of student work competencies to measure competency success. Therefore, this study aims to: (1) produce a product in the form of a practical performance assessment tool for students in the conveyor-based pandemic era with android control; (2) know the quality and performance of the developed tools; This research is development research using the method of combining the waterfall method and Borg Gall. This research focuses on product functionality so that testing is carried out by technicians with input from experts from the industry. The research data were obtained from observations, interviews, document studies, and questionnaires. The results of this study are as follows: (1) the product developed already has basic functions and can be operated using Android; (2) the results of testing by technicians from the aspects of functionality, reliability, efficiency, maintainability, and portability obtained a conformity percentage of 90% (Very Good), so that the tool can be used to test student work readiness in vocational schools or training institutions.
The development of ultrasonic sensor technology used for suitable equipment is widely carried out, such as distance sticks for the blind, floor cleaning robots, automatic garbage boxes, height measuring instruments, water volume detectors, automatic dispensers, automatic hand sanitisers, etc. During the COVID-19 pandemic, a product that can be used to limit the distance between humans is needed, so this research is focused on products for measuring distances with ultrasonic sensors. The research design method used is research and development, using the Borg and Gall approach, with step information collecting, planning, development, testing, final product and implementation. The results of this research product are designed using Arduino nano v3 hardware, battery, buzzer, and ultrasonic sensor HC-SR04. Product design was registered with Industrial Design Intellectual Property Rights with registration number A00202102408. The results of measuring the quality of the ultrasonic sensor for measuring distances on flat objects show an average error percentage of 2.94% from 10 cm to 300 cm with a distance range of 10 cm. Tests on obstacle objects (humans) at an angle of zero degrees and 15 degrees showed the best farthest measuring distance at a distance of 150 cm. So 150 cm is the best distance to apply to the hat COVID-19 reminder. The development results show that the product is ready to continue in production and sales.
