Abstract

Each material has a different type of toughness, such as the type of 10 mm nako iron material. In use, the material can be damaged. One of the factors that can cause damage is temperature. To find out how the effect of temperature on the material, one of the material tests was carried out, namely impact testing with the charpy method. This impact test is carried out on materials that have been given different temperature variations. There are 6 test specimens used at different temperatures. As a result, at the highest temperature, namely at 31 oC, the absorbed energy is 180.84 J with an impact price of 180.84 J/cm2 and at a low temperature, namely at 4 oC, the absorbed energy is 256.8 J with an impact price of 256 .8 J/cm2.

Abstract

The purpose of this PkM is to provide training and assistance regarding basic welding techniques that are useful for increasing student competence in welding. This training and mentoring in welding techniques serves as a provision for students to enter the world of work and entrepreneurship for SMK graduates as well as assisting the productive process of SMK students who lack funds and practicum facilities to improve their competence in the field of welding. The method used to solve the problems that occur is to use the survey method at SMK to obtain PkM data as needed, formulate training materials, schedule time-related training implementations, arrange instructors who will provide training, make activity evaluation designs, carry out training and mentoring activities Welding techniques were attended by students of SMK Samudra Indonesia, welding teachers, students and lecturers of Mechanical Engineering at the Medan State Polytechnic. The results of the PkM implementation are as follows: Welding skills that can equip SMK students to enter the world of work are being able to operate a welding machine properly and being able to connect plates using welding. The responses from SMK students who took part in the training and assistance from the Medan State Polytechnic Mechanical Engineering Study Program were as follows: they were happy because they had acquired welding skills that they had not mastered to their full potential and the teachers hoped that next year they could continue with other programs.
