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.

Abstract

In recent times, many studies have been carried out on desalination systems in areas that have difficulty in obtaining clean water sources. Desalination is a method used to distill salt water or brackish water into clean water using solar power as its energy source. This desalination process is a practical alternative that can be used to offer renewable energy sources that are used to produce clean water. To perform energy analysis, the first law of thermodynamics is used as a basis. This study aims to obtain the results of the amount of energy obtained from the solar desalination system and to determine the factors that greatly affect the amount of energy obtained from the system for evaporating water. The method used in this research is an experiment by testing a solar desalination device for eight days. The results show that the highest thermal energy produced is 8.98 kWh and the lowest is 1.56 kWh, and the factors that influence the amount of thermal energy are the heat transfer coefficient and the amount of distilled water produced by the system.

Abstract

One of the most frequently used methods of material testing is hardness testing. The aim of conducting research on material hardness is to determine the hardness value of the material specimens tested, namely ST 37 steel plate and aluminum plate. The test method is to use the Brinell hardness test where the values ​​obtained during testing are from the force load, indenter diameter and pressure trace diameter and the pressure time that has been determined. By using testing tools such as hardness tester, mechanical caliper, indenter, flat file, stopwatch. And the materials used are ST 37 steel plate, aluminum plate and sandpaper. From the test results obtained we can calculate the Brinell hardness value of the test material. The value from the calculation of test data where the highest hardness value using the Brinell method (BHN) for ST 37 steel plate material is 256.992. Meanwhile, the highest hardness value using the Brinell method (BHN) for aluminum plate material is 55,182.
