The Industrial Revolution Era 4.0 is a continuation of the era of society 3.0. One of the fields that experienced obstacles in facing this era was the industry sector. In creating experts in the industrial world, especially machinery, is not easy. One of the efforts made in improving the competence of workers in the field of machinery by adopting an appropriate learning model. During this learning model used in the field of machinery including work based learning and project based learning. These models experience constraints including the lack of relevance to the actual industrial world. This study discusses the effectiveness of the TEFA learning model in improving the quality of learning and ultimately producing machinery workers who have good competence in accordance with bloom's taxonomy at level 5

Abstrak. Several expert opinions regarding Project-based Learning (PjBL) are used in the appropriate learning process for students of the Department of Mechanical Engineering Education, Universitas Negeri Medan. The implementation is constrained by time allocation. This study provides solutions through hybrid learning collaborations with PjBL, aimed at equipping students with real problem-solving actions to create independent students and groups capable of critical thinking to find problem solutions packaged into projects through their skills and innovation. This research is a case study and analysis of project-based hybrid learning process management, especially in vocational education. The results of the study were obtained based on an agreement between the research team and internal vocational education curriculum experts by considering the time allocation for semester meetings, namely 16 meetings, that the project-based hybrid learning management process for vocational education consists of 4 steps, namely; 1) preparation stage, 2) planning stage, 3) implementation stage, 4) assessment and submission stage. This study refers to concepts previously used by experts by aligning the needs of students, attainment of course competencies and applying hybrid learning regulations that universities have set. Thus, the implications of hybrid project-based learning process management will be used as a reference in writing a pocketbook. Hybrid Project-Based Learning Process for Students.

This paper was purposed to determine the ability of coco fibers in reducing heat as a wall covering solution with different temperature levels. For the fulfillment of thermal comfort in buildings requires engineering, knowledge and skills and innovation. One way to reduce hot air in the room can be done through walls, thereby reducing the use of air conditioning. The walls need protection and solar heat absorbers that can make the room inside the building have thermal comfort. Based on this, research needs to be done on natural ingredients that can function to reduce heat. Tests carried out on coconut fiber and fiber-free materials. Material without fiber and coco fiber is 2 cm thickness of each. This coco fiber material is coated with a mixture of cement that also functions as a fiber adhesive. In this case, testing is conducted by applying heat of 60° Celsius and 40° Celsius to one side of the fiber and measuring the temperature that occurs on the other side of the fiber. The test results found that there was a significant difference between the heat temperature supplied and the heat temperature measured on coco fiber. The higher the temperature is received, the greater the heat that can be absorbed. This shows that coco fiber material has the ability to reduce heat at high enough heat as a wall covering against solar radiation.

This research is to develop learning material of machining technology with Teaching Factory Model approach based on metacognitive skill on Mechanical Engineering Education in Universitas Negeri Medan. The method used in research and development is development design of ADDIE. The results show that machinery technology lecture with Teaching Factory Model approach based on metacognitive skill is proper to be used with practicability level reach to 80.39%, and it is effective because resulting significant differentiation of study result value between experimental class and control class based on result of t experimental with value of tarithmetic = 2.72 and ttable = 2.021. Thus, Machining Technology Textbook by using Teaching Factory Based on Metacognitive Skill Model can be used practically and effectively in the learning process.
