The main competence of 21st century technical and vocational education and training (TVET) teachers is the ability to integrate technology into the learning process effectively. However, the concept of learning is now shifting to technological involvement, learning approaches, and needs in accordance with the curriculum of the world of work must be integrated to produce learning outcomes that are able to compete in obtaining work opportunities. The technological pedagogical content knowledge (TPACK) model used in general learning needs to be assessed according to the context of innovation in the TVET learning field. The purpose of this study is to analyze the teaching and learning of TVET teachers who are professionals with the approach of Technology, Andragogy and Work towards Content Knowledge (CK). Study of qualitative methods in the form of document analysis is identified by the philosophy of the learning approach at TVET and the current TVET learning model. The analysis results recommend that the technology andragogy work content knowledge (TAWOCK) model is considered important to be developed in TVET learning. Characteristics of these findings include the involvement of learning using technology, increasing the level of learning for andragogy, adjusting work competence, and curriculum content developed on the concept of knowledge. Finally TPACK has been modified to TAWOCK to study in the TVET field.

Online learning that is currently taking place causes problems because of the limited learning models that can be done online, so that it can reduce students' self-efficacy and motivation to learn. Learning with the help of Google Classroom is one solution that can be applied to online learning activities in order to increase self-efficacy and student learning motivation. This study aims to analyses the effect of the application of Google Classroom on increasing self-efficacy and student motivation in the Department of Electrical Power Installation Engineering (TITL). This research is a quasi-experimental study using a pretest-posttest design in the control class and the experimental class. The sample in this study amounted to 80 students from the Department of Electrical Power Installation Engineering. The observation method was used to collect data on self-efficacy and learning motivation during the pretest and posttest by using an instrument that was arranged based on indicators on the dependent variable. The data obtained were then tested for prerequisites and then the data were analyzed using paired sample t-test and independent sample t-test. The results of data analysis showed that the use of Google Classroom proved significant in increasing students' self-efficacy and learning motivation in online learning activities for students of the Electrical Engineering Department. Learning activities with the help of Google Classroom are significantly superior to learning activities without the help of Google Classroom.

This study used finite element analysis method to analyze the underbracket T triangle on motorcycles using ANSYS 2023 R1 software. The material used is Structural Steel. The simulation is done by accurately modeling the triangle and meshing using the default algorithm. The boundary conditions are set by providing fixed support at all four-hole points and providing a load of 1000N on the Y-axis. The simulation results show a maximum equivalent stress (Von-Mises stress) of 7.173 MPa, which is still below the strength limit of the material. The underbracket T-triangle undergoes a maximum deformation of 0.00063309 mm at the upper right fork hole. This deformation indicates the extent to which the triangle changes shape due to the load applied. The safety factor obtained is greater than 1, indicating that the triangle has adequate safety to withstand the load. With a better understanding of the structural behavior of the underbracket triangle, the design can be improved to improve the strength and performance of the motorcycle.
