Guru diharapkan dapat meningkatkan kompetensi salah satunya dalam penguasaan Teknologi Informasi dan Komunikasi (TIK). Hal ini diperlukan untuk mendukung kegiatan pembelajaran yang menarik, efektif dan efisien. Oleh karenanya, perlu diadakan suatu kegiatan atau pelatihan untuk menambah pengetahuan/wawasan dan keterampilan guru tentang TIK. Pelatihan yang diberikan diharapkan dapat diaplikasikan guru dalam penggunaan media teknologi informasi untuk meningkatkan efektifitas dan efisiensi dalam kegiatan belajar mengajar. Berdasarkan kondisi yang terjadi sekarang terdapat beberapa masalah yang akan diatasi pada kegiatan ini, antara lain pemanfaatan penggunaan smartphone oleh guru dan peserta didik masih sebatas pada alat komunikasi dan hiburan, padahal dapat dioptimalkan penggunaannya sebagai media pembelajaran berbasis android. Tujuan dari kegiatan pengabdian masyarakat ini adalah untuk meningkatkan kompetensi pedagodik guru dan kemampuan guru dalam membuat media pembelajaran yang interaktif. Metode yang digunakan dalam pelatihan ini adalah ceramah, demonstrasi dan praktik. Teknik pengumpulan data menggunakan angket mengenai persepsi peserta terhadap pelaksanaan pelatihan. Indikator keberhasilan pelatihan ini meliputi tingkat pembelajaran, tingkat perilaku, tingkat reaksi dan tingkat hasil. Hasil yang diperoleh dari pengolahan data keseluruhan indikator adalah peserta setuju bahwa pelaksanaan pelatihan telah berjalan dengan baik, dimana sebagian besar peserta berpandangan bahwa pelaksanaan pelatihan telah memberikan manfaat yang mendalam dan sangat membantu dalam peningkatan kualitas diri peserta.
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.
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.
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.
Electrical Measurement and Instrumentation is an important thing that must be mastered by electrical engineering students. But the problem that arises is the decreased interest in reading books, so that students need the other ways of learning. Then by utilizing the development of android technology, this study aims to develop the android based learning media to assist students to understanding the material. This research was adopted 4D model that have 4 development steps (define, design, develop, disseminate). Validity of the media was measured by instrument of validity that had been validated before. The average calculation result from the validity analysis of the learning media is 85% with valid category. So it can be concluded that android based learning media on Electrical Measurement and Instrumentation course was valid to be used as a learning media.
