Abstract

The technology of components and electronic hardware has evolved to be able to produce a DC/DC current system for power, which is achieved by converting the DC power to higher or lower voltage. This DC voltage variable is commonly called the DC-DC Converter. This final task aims to find out the performance of the DC-DC Sepic Converter series design. The simulated testing of the system using SIMULINK/MATLAB software is subsequently obtained from the data analysis of the theoretical output voltage data and the monitoring of measurements that can be analyzed to determine the error level as well as the level of efficiency of the design of the sepic converter. The test was conducted by setting a constant input voltage of 12 V, a frequency of 50 kHz, with a duty cycle variation of 5% to 65% and a given load of 20 Ω. The result of the design of the Sepic Converter at the time of open loop mode with the value of duty Cycle of 5% produces a minimum voltage that is 0,38 V. Subsequently, when given the duty cicle value of 65%, the maximum voltage is 21,22 V error with the highest error rate of 1 V obtained at the 13th data trial. The average error value is 0,642 V and the standard deviation value is 0,453 V, the greatest efficiency point is 78,50% at the moment of the cycle duty value of 65. While the results of the testing of the Set of Sepic Konverters at the close loop mode, the input tension is given constantly 12 V. The configuration for the parameter value of PI is also constant, namely at the set point of 22,22 V, it is 21,97 V with an error difference 0,25 V.

Abstract

Many people do not understand how to use household electricity safely and economically. The above problems are also experienced by residents in Cemare Hamlet, Lembar Selatan Village, Lembar District, Lombok Barat Regency. To overcome this problem, the solution offered to the residents of Cemare Hamlet is to carry out counselling regarding this matter. This counseling will enable the residents of Cemare Hamlet to understand how to use household electricity safely and economically so that it can support the safety and efficiency of sustainable use of household electricity. On the day agreed between the counselling team and the residents of the hamlet, this counselling was carried out at the house of one of the residents of the hamlet. After most of the residents had attended, the event finally began. The counseling began with remarks from the team of the Department of Electrical Engineering, Faculty of Engineering, Mataram University, followed by counselling and questions and answers regarding the counselling material. Next, a written and verbal evaluation was carried out (because there were residents who were still illiterate) by the counselling team to the hamlet residents. There are 10 questions given, each worth 10 related to the counseling material that was given previously. The results obtained were that 73.33% of participants answered the questions given with a score of fair to very good, while 26.66% of participants answered the questions given with a score of very poor to poor. These results show that this counselling activity has provided knowledge to residents of Cemare Hamlet regarding the safe and economical use of household electricity.

Abstract

In the rapidly developing digital era, technical skills in information and communication technology are very important for Vocational High School (SMK) students, especially those who are doing internships. Mastery of computer hardware, such as installation and maintenance, is a vital skill to compete in the world of work. Intensive training in computer hardware installation during internships aims to improve the competence of vocational high school students, making them better prepared to face industry demands.The training methods used include planning based on needs analysis, orientation, balanced implementation between theory and practice, and continuous evaluation. This training succeeded in improving students' practical and theoretical skills, with 85% of participants being able to complete installation tasks well. In addition, the average student score in the theory exam increased from 60% to 85%. As many as 80% of participants obtained competency certificates, which increased their competitiveness in the job market.In conclusion, this training is effective in improving the technical competence of vocational high school students in computer hardware installation, making them better prepared to enter the world of work.
