Tegangan listrik merupakan salah satu faktor penentu dalam kualitas suatu sistem tenaga listrik. Tegangan lebih, tegangan kurang dan stabilitas tegangan, adalah masalah utama dalam masalah tegangan listrik, penelitian ini bertujuan untuk mengevaluasi penurunan tegangan dalam sistem distribusi tegangan menengah 20 kV di PT.PLN Rayon Kuala Simpang. Penelitian ini diharapkan menjadi acuan untuk melakukan perbaikan tegangan dan meningkatkan kualitas layanan tenaga listrik yang lebih baik. Penelitian ini dilakukan pada jaringan radial sistem distribusi utama di mana jatuh tegangan diamati pada tiga keadaan dalam sistem yaitu pada saat Distributed Generation terhubung dengan sistem distribusi, pada saat Distributed Generation tidak terhubung dengan sistem distribusi dan pada saat sebelu dan setelah pergantian kabel. Pengumpulan data dilakukan sesuai dengan data yang diperlukan dalam menganalisis penurunan tegangan dengan simulasi aliran beban menggunakan perangkat lunak ETAP 12.6, hasil yang diperoleh kemudian divalidasi dengan membandingkan hasil simulasi dengan perhitungan manual sesuai dengan rumus yang terkait dan berlaku untuk perhitungan jatuh tegangan, dari hasil simulasi menunjukkan bahwa penurunan tegangan terbesar dan terkecil pada saat tanpa Disributed Generation (DG) masing-masing pada bus 87 dan bus Marlempang yaitu 97,145% dan 97,926% , nilai tersebut masih dalam batas standard untuk under voltage maksimum 10%. Pada saat Disributed Generation terhubung ke jaringan distribusi penurunan tegangan terbesar dan terkecil masing-masing pada bus 87 dan bus Marlempang yaitu 97,635% dan 98,42%. Perbaikan jatuh tegangan akibat pergantian kabel saluran distribusi dari ukuran 70 mm2 menjadi ukuran 150 mm2 sepanjang 2,746 km mulai dari bus 275 sampai dengan bus 207 menyebabkan jatuh tegangan maksimum dan minimum berkurang masing-masing pada bus 87 dan bus Marlempang menjadi 97,637% dan 98,422%. Pengaruh keberadaan pembangkit menyebabkan pembagian distribusi arus tidak terjadi pada satu sumber sehingga menyebabkan perhitungan nilai impedansi saluran terhadap keberadaan arus nominalnya menjadi berubah dan menyebabkan jatuh tegangan yang berkurang pada hampir seluruh bus sistem. Sedangkan pergantin kabel saluran distribusi dengan diameter yang semakin besar menyebabkan nilai impedansi saluran semakin mengecil yang mengakibatkan jatuh tegangan di seluruh bus sistem mengalami perubahan menjadi lebih kecil

The research of over temperature protection systems on solar power generation inverters using Arduino aims to design an over temperature protection system on PLTS inverters using Arduino so that there is no reduction in efficiency and prevents the inverter components from damage due to heating. The method used is an experimental method that is designing an over temperature protection system on the inverter to get good design results. The equipment used is solar panels, inverters, fan motors, L298N drivers, Arduino and batteries. The results showed that the over temperature protection system equipment on the PLTS inverter using Arduino was able to protect the over heating in the inverter, especially to increase the load from 272 watts to 532 watts with an increase in temperature of only 0.1 0C. For the use of an inverter for a long time, the temperature inside the inverter in the previous state greatly affects the temperature inside the inverter in the next state so that the temperature decrease along with the linear load decrease is difficult to achieve, especially at 630 watts with an inverter temperature of 37.6 0C, some time after that a decrease in load occurs until the load becomes 105 watts but the temperature value in the inverter has a value greater than the 630 watts loading that is equal to 37.9 0C

The spread of the Covid-19 virus which continues to grow and is worrying to date with its increasing number of victims, encourages the Government to continue to take measures to prevent the spread of the Corona virus. One of the government's efforts to prevent COVID-19 is to monitor the health condition of the human body. One of them is detecting the human body temperature, because body temperature with a temperature above a certain limit is one of the symptoms of covid-19. The normal human body temperature ranges from 36 degrees to 37 degrees. However, for the current situation related to the corona virus pandemic, temperatures above 37 degrees have become temperatures that must be watched out for. This study aims to make a prototype of a body temperature monitoring system for the prevention of Covid-19 based on Internet of Things (IoT) The prototype designed uses an AMG8833 thermal sensor which will measure a person's body temperature with infrared which can identify a person's health through his body heat and also uses an ultrasonic sensor to measure a person's distance with the thermal sensor. The results of body temperature monitoring can be accessed on the cellphone through the blink application. From the results of the discussion, it was found that the body temperature monitoring system for the prevention of Covid-19 using AMG8833 thermal sensor the based on IoT was successfully designed and implemented in a prototype form. AMG 8833 thermal sensor works well in measuring human body temperature up to a distance of 20 with an average error of 1.18%.

Program Pengabdian Kemitraan Masyarakat yang dilaksanankan di Sekolah Menengah Kejuruan Dr.Cipto Mangun Kusumo merupakan bagian dari kegiatan rutin pengabdian masyarakat Politeknik Negeri Medan. Tujuan dilaksanakan pengabdian adalah untuk memberikan sumbangan dalam bentuk peralatan berupa Lcd proyektor dan pelatihan kepada guru-guru sekolah Dr.Cipto Mangun Kusumo tentang cara pembuatan video pembelajaran menggunakan bandi cam yang dikombinasikan dengan power point dan penggunaan aplikasi meeting google meet dan zoom. Target khusus yang ingin dicapai adalah para guru dapat membuat video pembelajaran sederhana dan dapat menggunakan aplikasi meeting menggunakan google meet dan zoom baik sebagai host maupun partisipan dan diharapkan setelah pelatihan para guru yang mengikuti pelatihan dapat membagikan ilmunya kepada para guru lainnya atau rekan sejawat yang tidak mengikuti pelatihan. Metode yang akan digunakan untuk mencapai tujuan tersebut adalah metode tatap muka terbatas yang selalu menerapkan protokol kesehatan sekaligus metode penugasan kepada peserta pelatihan. Kegiatan yang dilakukan adalah memberikan materi pelatihan sesuai dengan buku panduan yang dibuat sebelumnya oleh tim pengabdian dan mempraktekannya langsung terhadap sesama peserta pelatihan. Kegiatan berlangsung selama satu hari pada tanggal 3 Desember 2021 yang diikuti oleh 18 guru. Dari hasil pengamatan kegiatan dan wawancara kepada guru diperoleh kesimpulan bahwa terbatasnya jumlah Lcd Proyektor untuk kebutuhan proses belajar mengajar membuat para guru enggan mempersiapkan materi pembelajaran dalam bentuk video pembelajaran yang inovatif, dan penggunaan aplikasi meeting menggunakan google meet lebih diminati oleh guru karena aplikasi tersebut gratis dan mudah digunakan serta durasi meeting tidak dibatasi. Sedangkan penggunaan video pembelajaran menggunakan bandicam baik digunakan dalam pembelajaran luring dan daring, untuk pembelajaran luring dengan pertemuan tatap muka terbatas maka video pembelajaran menggunakan bandicam menjadikan proses belajar mengajar lebih efektif karena guru hanya menjelaskan ulang hal-hal penting dan yang menjadi pertanyaan peserta didik sehingga waktu yang digunakan cukup efektif dan peserta didik mempunyai dokumen file rekaman guru ketika menerangkan materi pembelajaran
