Gambar Teknik dan Listrik merupakan salah satu mata kuliah wajib yang harus dipelajari oleh mahasiswa . Dalam pelaksanaan pembelajaran mata kuliah ini masih dilakukan secara manual yaitu menggunakan pensil dan kertas gambar. Namun era komputerisasi sekarang  pembelajaran Gambar Teknik dan Listrik perlu diimbangi dengan kemajuan zaman. Salah satunya menggunakan software AutoCAD dalam menyelesaikan materi gambar yang ada. Oleh karena itu, butuh pengembangan bahan ajar modul dengan tutorial bisa membantu untuk memahami penggunaan software dalam menyelesaikan materi. Penelitian ini bertujuan untuk mengetahui validitas modul tutorial Gambar dan Teknik dengan AutoCAD yang telah dikembangkan. Data penelitian diperoleh dari analisis angket uji validitas oleh validator yang terdiri 2 orang ahli materi dan media. Hasil uji validitas modul tutorial AutoCAD yang dinilai validator memperoleh nilai rata –rata 111 untuk ahli materi pada kategori valid sedangkan untuk ahli media mencapai nilai rata rata skor 120 dengan kategori sangat valid.

Internet of thing (IoT) is a system that will change the order of human life and industrial operations. In the future, objects that are operated daily with human interaction will be equipped with internet connectivity which is equipped with various sensors so that they are able to communicate and act on the information obtained without human intervention. The problem is that the ecosystem has not been fully developed as well as from the world of education which will prepare its human resources. Apart from that, the industrial sector which is predicted to be the largest user is still considering various things such as cost, security, non-conformity with the existing system and the ability of its resources. The system created is an effort to develop knowledge in the IoT field as an effort to bridge the need for human resources, especially at the Vocational High School (SMK) level. This IoT application for electrical load control is designed and built using the main components of NodeMcu V3, 4 channel relay, and Android with the Blynk application installed. Electrical load control commands are given using the Blynk application via Android and delivered to the NodeMcu V3 module using a Wifi intermediary and from NodeMcu V3 forwarded to 4 channel relays to control electrical loads in the form of ON and OFF. The results of the test show that the system built can operate properly in controlling electrical loads

This study reveals the improvement of community competence, especially youth after participating in the Installation and Maintenance training program for Simple House Installations in Padang City. The competence in question is the ability in the field of installation and maintenance of simple house installations at the household level in the community. The increase in the ability of the training participants is measured using a research instrument in the form of a Performance Assessment Rubric that has gone through a validation process. The research data were analyzed by percentage analysis and interpreted with an improvement table to get the level of improvement achieved. The research subjects were as many as 15 trainees who were representatives of members of the youth organizations of each sub-district in the city of Padang. The results showed that the average participants experienced an increase in the installation and maintenance of simple home electrical installations after participating in training activities where the increase was at a very high level (total average = 83.32). Thus, it can be concluded that the training program held was able to improve the competence of youth youth organizations in the city of Padang in the field of installation and maintenance of simple house installations.

The growth of the electric power system is currently taking place rapidly, causing an increase in the number and length of line to provide consumer services. In the line, there are often fault caused by lightning, storms, breakdown insulation, and short circuit caused by birds and other objects. Detection and location determination will speed up the repair process and can avoid more severe damage. Most studies refer to the fault location on the transmission line. But lately the determination of fault location in distribution system has begun to become a concern of researchers for the improvement of the quality of electricity services to consumers. This study discusses the determination of fault locations based on fault currents and the types of disturbances using data from the assumed distribution system model. The estimated fault location by ignoring the fault resistance has the largest error obtained 0.74% and estimated fault location by including fault resistance will cause a very large error, but the error can be reduced by changing the algorithm of the fault resistance assumption. The result for to ground fault error has reached 1.238% and double line to ground error has reached 88.167%.Keywords— Fault location, fault current, fault resistance, distribution system
