“…Catu daya (power supply) adalah suatu alat listrik yang dapat menyediakan energi listrik untuk perangkat listrik ataupun elektronik lainnya. Pada dasarnya power supply atau catu daya ini memerlukan sumber energi listrik arus bolak-balik (alternating current, AC) agar dapat diubah menjadi energi listrik arus searah (direct current, DC), yang dibutuhkan oleh perangkat elektronik lainnya [6], rangkaian power supply digunakan mengubah tegangan AC PLN 220V menjadi tegangan DC 5V digunakan sebagai sumber tegangan perangkat mikrokontroler sehingga input dan output yang terhubung ke mikrokontroler akan berfungsi [7].…”

Abstrak-Pengolahan makanan yang sehat dan baik dibutuhkan untuk mewujudkan kesehatan yang baik bagi masyarakat, teknologi yang murah dan aman diharapkan dapat mendukung sistem pengolahan makanan yang baik, salah satu pemanfaatan teknologi adalah dengan penggunaan oven listrik otomatis dalam kehidupan sehari-hari, sehingga proses pemanggangan bahan makanan dapat dilakukan secara otomatis, pengendalian temperatur pada oven membutuhkan sistem kontrol yang baik, sistem pengontrolan PID dapat diterapkan pada oven listrik untuk mengatur temperatur yang diberikan pada oven listrik, penelitian menggunakan sumber tegangan PLN 220 volt, heater sebagai elemen pemanas, power supply 12 volt DC digunakan untuk menjalankan beberapa komponen, besarnya temperatur yang akan diatur di masukkan oleh tacticle button ke Arduino Uno, nilai masukan akan diproses oleh Arduino Uno dan ditampilkan di display LCD, Kontroler PID akan mengatur temperatur yang diinginkan dengan mempertahankan nilai set point temperatur yang diinginkan, temperatur pada oven akan terus bertambah sebelum mencapai set point yang diinginkan dan akan berkurang setelah melebihi set point yang diizinkan, pemutus tegangan Solid state relay akan memutus heater jika temperatur pada oven melebihi temperatur yang izinkan, sehingga temperatur oven akan kembali sesuai temperatur yang diizinkan, hasil pengujian membuktikan saat set point diatur 60 o C dan 100 o C, temperatur oven tidak mengalami perubahan temperatur sesuai set point yang diatur.

“…Si ultrafast recovery diodes (Si FRDs) can reduce power loss owing to their highly efficient switching performances [1,2]. Recently, they have been implemented in highfrequency applications such as switching power supplies [3][4][5], in which a reduction in power consumption is crucial. The introduction of lifetime killers [6] into semiconductor devices is required to reduce the switching time.…”

We investigated the reduction in the reverse-biased leakage current of Si ultrafast recovery diodes via a combined lifetime process involving Au diffusion and bulk electron-beam irradiation (EI). The leakage current of the combined-processed diode was significantly reduced to less than one-third of that of the diode processed solely with Au diffusion, maintaining a similar switching time of 32 ns. This reduction was not achievable with the sole use of EI. Deep-level transient spectroscopy revealed that the reduction in the leakage current was due to the coexistence of the deep trap level of Au (E c-0.51 eV) and the shallow trap level of the defects (E c-0.39 eV) generated via EI as lifetime killers. By combining the deep and shallow trap levels, the lifetime of the carriers generated in the depletion layer of the reverse-biased p-n junction becomes long and consequently, the leakage current is reduced. By maintaining the trap density ratio of defects to diffused Au above 0.28, the leakage current was reduced to less than one-third of that in the solely Au-diffused diode, while maintaining a similar switching time.

Long Term Evolution (LTE) the fourth generation (4G) cellular network technology. This LTE speed in data transfer speed reaching 100 Mbps on the side downlink and 50 Mbps on the uplink side. Growth in the number of service users telecommunication in Medan City causes a decrease in network quality, especially 4G LTE technology. By doing a driving test, the area can be found where a system’s signal strength aims to increase the signal quality. Benchmark (comparison) of operator service quality 4G LTE is done by measuring, comparing, and analyzing network quality (performance) of two 4G LTE operators around Muhammadiyah University of North Sumatra. Total operator throughput value X is only 0 > 3 Mbps while the Y operator is 0 > 30 Mbps. The low throughput value is caused by high user traffic during the day. The incidence of low throughput on the Muhammadiyah University of North Sumatra campus coincides with active learning with many students using data services.
