Umumnya solar cell yang dipasang hanya menghadap satu arah tertentu saja. Gerak semu harian matahari menyebabkan perubahan posisi matahari dari timur ke barat setiap harinya. Perubahan posisi matahari tersebut membuat modul solar cell tidak selalu mendapatkan intensitas cahaya matahari yang maksimal sepanjang hari. Salah satu cara yang dapat dilakukan supaya solar cell mendapatkan intensitas cahaya matahari yang maksimal sepanjang hari adalah dengan menempatkan modul solar cell tegak lurus mengikuti cahaya matahari. Hal tersebut yang melatarbelakangi pembuatan alat tracking cahaya matahari menggunakan komponen Light Dependent Resistor (LDR) sebagai sensor dan motor linear aktuator parabola sebagai penggerak posisi modul solar cell. Cahaya matahari yang mengenai sensor LDR membuat resistansinya berubah sehingga mempengaruhi nilai tegangan yang akan diinformasikan ke analog input mikrokontroller. Mikrokontroller mengolah informasi yang diterima dari sensor LDR dan memberi perintah untuk menggerakkan linear aktuator yang mana akan menggerakkan posisi permukaan modul solar cell dengan dua arah yaitu mengikuti orientasi gerak semu harian matahari dari arah timur ke arah barat. Pada arah timur dan barat masing-masing terdapat sebuah limit switch. Ketika malam hari modul solar cell ini akan kembali bergerak menghadap ke arah Timur dan akan berhenti ketika limit switch Timur aktif. Alat tracking cahaya matahari ini telah dilakukan uji coba. Alat ini telah dapat mengikuti pergerakan matahari dari timur ke barat dengan daya keluaran solar cell dari 8,71 watt mampu ditingkatkan menjadi 12,46 watt dengan konsumsi daya motor sebesar 2,08 watt.

Pembelajaran Dasar dan Pengukuran Listrik adalah mata pelajaran produktif yang diberikan di Sekolah Menengah Kejuruan. Pembelajaran ini mendukung pengetahuan awal siswa tingkat/kelas selanjutnya. Tujuan pembelajaran ini adalah mendidik, melatih dan menyiapkan pemahaman siswa dalam bidang bahan-bahan listrik seperti bahan-bahan listrik pasif. Peserta didik akan kesulitan memahami dan mengerti tentang komponen tersebut jika guru hanya menjelaskan dengan metode ceramah tanpa berbantuan media. Karena itu diperlukan alat bantu seperti media trainer yaitu sebuah alat peraga dengan model dan ukuran yang disesuaikan dengan fungsi serta kegunaannya yang bisa membantu meningkatkan pemahaman siswa yang lebih optimal juga meningkatkan keaktifan, kreatifitas dan mendapatkan hasil yang lebih pada mata pelajaran ini. Pengembangan media pembelajaran trainer yang valid, praktis dan efektif dalam rangka penyempurnaan media pembelajaran diharapkan menjadi solusi praktis menjawab permasalahan tersebut. Media dapat dimanfaatkan dalam proses pembelajaran untuk meningkatkan keinginan dan minat belajar, membangkitkan motivasi dan rangsangan kegiatan belajar dan bahkan berpengaruh terhadap psikologis siswa.

Problems that often occur in the use of solar panels are the efficiency of solar panels and monitoring of solar panel generating systems. Monitoring of the output parameters of solar panels is very necessary to assess the performance and efficiency of a solar panel in real environmental conditions. Internet of Things (IoT) can make devices communicate with each other such as sending and receiving data. A monitoring system based on a wireless sensor network was created to make it easier to get direct and real time information on the output parameter data of the solar panels. The research objective is to create a monitoring system on a solar panel using Visual Basic and Blynk applications. This system is designed to determine the output parameters of the solar panel in the form of current, voltage, light intensity, and position which are processed directly and displayed in tables and graphs in Real Time conditions. The use of logger data in this monitoring system is very important. From the results of tests carried out on this monitoring system, the system is able to record and read the output parameters regarding the resulting current and voltage data as well as light intensity and the position of the solar panels. Information about measurement data from each sensor will be stored in the database and can be obtained directly through an excel spreadsheet.

Increasing teacher competency is a process that cannot be done instantly. Teachers must always be provided with new knowledge that can be applied to their own needs and institutions. Computer-based learning will greatly help educators in the current era of Information and Communication Technology, especially vocational teachers who teach in productive fields (engineering subjects). The problem faced is the inability of teachers to use computers as learning media. Teachers only use computers to present powerpoint media, even in practical subjects. The teacher has not been able to utilize software engineering that will assist in the practical learning process, such as AutoCAD software in learning Drawing Engineering and PLC software in learning control systems. Therefore, it is necessary to conduct integrated and comprehensive training for teachers in utilizing computers as learning media especially in the use of software engineering. All Muhammadiyah 1 Padang Vocational Middle School teachers and SMK Dhuafa Nusantara Padang were invited to take part in engineering training. In the implementation of the activity there were 15 teacher participants. The training material consisted of the introduction and use of AutoCAD software, and PLC software. The results of this training show that more than 90% of participants have been able to use AutoCAD and PLC software. Besides that, there was an increase in motivation and enthusiasm from the teacher to show performance, both in the use of software for classroom learning and in daily life as a professional who always tried to improve his competence.

Aware of the importance of an internet connection today, UNP has facilitated an internet wifi network to support the needs of academic, non-academic staff, and students. This wifi network can be enjoyed throughout the campus environment including the electrical engineering department which is connected through several hotspots throughout the campus. However, the strong network signal is considered unstable and not evenly distributed to serve all civitas, especially for the students. In some places, the signal level received is very weak. While in other locations, the user did not get a signal or better known as the blankspot. This is due to the fact that the installed access points are not optimal, both in terms of number and in the position of its installation. Access points positioning by providing certain conditions can also be made so that signal build-up in one area and blankspot conditions in other areas can be avoided. For this reason, it is necessary to analyze, calculate and plan the position of the access point before the tool is installed. To calculate the exact number of access points, it is necessary to estimate the number of daily bandwidth requirements in the electrical engineering department. Then calculate the number of access points both in terms of capacity and coverage. Last, a simulation will be carried out so that the best access point installation position will be obtained.

Penyimpanan biji kacang tanah tanpa kulit ari di toko grosiran sudah memanfaatkan teknologi pengemasan vakum. Akan tetapi pada pengencer pasar atau toko kecil masih menggunakan metode konvensional. Penyimpanan secara konvensional menyebabkan tidak terjaganya mutu biji kacang tanah yang disimpan oleh pengencer pasar. Salah satu cara untuk mengatasinya adalah dengan menerapkan pengemasan vakum. Penelitian ini bertujuan untuk merancang dan membuat sebuah alat vakum kemasan menggunakan mikrokontroler ATMega328P sebagai kendali alat tersebut. Alat ini dirancang untuk melakukan pemvakuman yang disertai dengan penyegelan kemasan menggunakan sealer. Apabila mikrokontroler menerima sinyal dari sensor infrared yang mendeteksi keberadaan kemasan di atas tatakan, maka button berfungsi sebagai tombol start. Dengan menekan button maka alat akan mengeluaran udara di dalam kemasan menggunakan motor DC yang setelahnya diiringi dengan penyegelan kemasan kacang sehingga dihasilkanlah pengemasan kacang secara vakum. Berdasarkan uji coba yang telah dilakukan, alat ini membutuhkan daya sebesar 7 Watt dengan durasi pengoperasian selama 22,21 sekon. Alat ini juga mampu mengeluarkan udara di dalam kemasan. Jadi disimpulkan bahwa alat ini bekerja dengan baik.

The design of thesis data collection system aims to record the title of the thesis that has been made by students and also to find out the number of students who are guided by each lecturer, and to avoid working on the same thesis title between one student and another. The taking of the same title mostly occurs in students who are in the process of carrying out research. This happens because students are less active in finding out the titles that have been discussed and also because the facilities to access titles that have been registered in the Electrical Engineering Department of UNP do not yet exist. In this data collection system, there is information on titles that have been registered in the Department of Electrical Engineering, UNP, and also information on the list of names of students under the guidance of lecturers and the titles of theses that are in progress. The method of making this data collection system uses 2 steps. The first is creating a database using XAMPP software, and then making a web database using visual studio code. After testing the system that has been designed, it can be concluded that the system has been running as planned. With this data collection system, it can be seen that there will no longer be the same student title and also information on the number of students who are mentored by lecturers.

SMK N 1 Koto XI Tarusan is one of the SMK’s that develops new study programs namely Teknik Audio Video (TAV), one of the goals is to prepare the students to have the skills to enter employment in companies engaged in electronics in addition to continuing to the level of higher education. Department of Audio Video Engineering is more directed to the electronics field, but in all teaching and learning activities especially practical activities using equipment related to electricity, such as power supplies. But they do not have good knowledge about power supplies because power supplies are basic knowledge of electricity that is not specifically studied in the field of Audio Video Engineering. Thus, teachers must be equipped with adequate skills, so that these skills can be transferred to their students. The provision of skills for these teachers is carried out by providing training in making power supplies with variable outputs. The method of conducting training is direct practice, with 3 stages. The first stage was that participants were given knowledge about power supply theory, about how to design power supply circuits and calculate component and design requirements. The second or core stage, the trainees did the practice of making layouts, the practice of designing the power supply, the practice of calculating the value of the components needed, and assembling the power supply itself such as making a PCB layout, and making a variable power supply trainer. While, the third stage or the final stage is troubleshooting to test the power supply that is made to function properly/not. The training that was carried out was also analyzed with several indicators to see whether the training provided an increase in skills to the participants/not. From the training that has been carried out, the trainees can make 10 sets of 0-30 Volt variable power supplies that can be functioned properly. The training can also improve the participants' skills which are analyzed from several indicators: learning, behavior, reaction, and results. Testing with these indicators shows that the implementation of the training has provided profound benefits and is very helpful in improving the participants' self quality. Keywords: Training, Skill Improvement, Variable Power Supply
