<![CDATA[Matrix converter is a good choice for Permanent Magnet Synchronous Motor (PMSM) drives, because it has high power density and does not require dc-link energy storage. the disadvantages of conventional matrix converter is using 18 active switches, so it becomes expensive and the modulation method becomes more complicated than back to back converter. To minimize this problem, this paper proposes variable speed drive of PMSM using Ultra Sparse Matrix Converter (USMC) based on Direct Torque Control (DTC) methods. This converter uses only 9 active switches, making it cheaper than conventional matrix converter. DTC is designed based on Space Vector Modulation (SVM) to reduce torque and flux ripples due to the hysteresis control in conventional DTC. The simulation results show that DTC based SVM using USMC effectively controls the rotor speed with low torque and flux ripples.]]>

<![CDATA[Abstract—The potential for solar energy sources is so large that it has not been optimally utilized, as a renewable energy source. The use of solar energy as a generator of electricity is very potential to be developed in West Sumatra Province. We know that the price of electricity obtained from this non-renewable energy is much more expensive in the short term, but it is much more valuable when calculated in the long term, especially from the aspect of environmental protection. The continuity of electrical services can always be fulfilled. It is necessary to combine PLN electricity sources and electricity sourced from solar energy as an alternative so that the reliability of the supply of electrical energy can be maintained. However, the large potential of renewable energy sources has not been able to be utilized optimally by the wider community, due to the limited competence of human resources who are able to utilize this energy. Through community service activities, Padang State University in collaboration with the Budi Utama Youth Assisted Child Orphanage in Lubuk Alung tries to make a contribution to improving Human Resource Competence through empowerment and community training with an integrated and sustainable process. One of the competency improvement activities carried out is training on the skills of installing electricity from PLN sources and solar energy installations. This training activity aims to provide understanding in the planning, design, operation, and maintenance of PLN sources and solar panel installations. The end result of this training is being able to provide education, increase skills, and competencies to participants to improve technical skills.]]>

<![CDATA[The heart is a human organ that pumps blood. The heart contracts, where one contraction cycle is usually called a heartbeat. Calculation of heart rate is often done manually by counting the pulse on the wrist for one minute. This method is considered inaccurate because it only relies on the human sense of touch. By making it easier to calculate the heart rate with the Electrocardiograph (ECG) device only but this tool is used in hospitals and cannot be moved. With a sensor that makes daily activities easier. For example, a pulse sensor that is easily available is a pulse sensor that can be used to detect the human heartbeat. With the heart rate device that can be moved using a pulse sensor. Where in the tool that in this final project detects the heart rate will be displayed on the Liquid Crisytal Display (LCD) where the detection results displayed are the results of the detection of human heartbeats accompanied by diseases that may be experienced from heart rate abnormalities.]]>

<![CDATA[Tanaman merupakan tumbuhan yang dibudidayakan agar dapat diambil manfaatnya oleh sebab itu memerlukan perawatan yang intensif berupa penyiraman dan pemupukan yang teratur sesuai dengan resistensi media tanam dan karakteristik dari tanaman. Diberbagai daerah petani masih melakukan penyiraman dan pemupukan secara manual cara tersebut kurang efektif karena debit air tidak sesuai dengan kebutuhan dan menghabiskan tenaga dan waktu yang cukup lama. Maka dari itu petani untuk segera beralih ke system otomatisasi penyiraman dan pemberian pupuk cair pada tanaman. Pemberian air dan pupuk pada tanaman secara otomatis yang dikendalikan oleh mikrokontroller arduino sebagai pusat kontrol dan beberapa komponen sebagai alat pendukung dari sistem otomatis berdasarkan data hasil pengukuran menjadi solusi untuk meringankan pekerjaan dan meningkatkan produktivitas tanaman. System otomatis bekerja berdasarkan informasi beberapa sensor mengenai kondisi tanah pada tanaman dengan pengontrolan mikrokontroller arduino. Penyiraman tanaman dilakukan ketika sensor soil moisture membaca kelembaban tanah sesuai dengan set point yang telah ditentukan yaitu pada range >700, dan penyiraman akan berhenti ketika tanah pada tanaman dalam keadaan basah dan sesuai dengan set point yang telah ditentukan pada range >650. Dan untuk pemberian pupuk cair pada tanaman menggunakan RTC yang berfungsi sebagai penjadwalan pemberian pupuk cair yang terlebih dahulu dilakukan setting hari dan waktu pada program sesuai dengan set point yang telah dilakukan.]]>

<![CDATA[Pada era teknologi yang semakin berkembang pesat, penggunaan elektronika daya semakin banyak digunakan seperti untuk penggontrolan motor dan lain – lain. Untuk mendukung semua itu tentu juga di iringi dengan metode – metode interfacing yang memudahkan user dalam penggunaaan alat – alat elektronika daya seperti contohnya buck conveter. Interfacing yang di maksud disini adalah dengan melakukan pengaturan keluaran buck converter dengan menggunakan interfacing pada personal computer sekaligus memonitoringnya. Buck converter adalah jenis dc-dc converter yang berfungsi untuk mengubah keluaran tegangan output lebh kecil dibandingkan dengan tegangan keluaran input. Perancangan monitoring menggunakan visual basic dalam pembuatan interfacing, hal ini dilakukan karena kemudahan komunikasi antara visual basic dengan arduino. Metode pengontrolan menggunakan pengaturan duty cycle yang diberikan dari visual basic ke arduino. Dengan mengatur duty cycle, maka tegangan yang dkeluarkan pun akan berubah-ubah. Berdasarkan hasil pengujiaan, maka dengan memperbesar duty cycle maka keluaran tegangan dari buck converter akan semakin kecil, Dengan hasil pengukuran buck converter pada input tegangan 24 volt dan duty 15.97 menghasilkan tegangan keluaran sebesar 19,5 sedangkan pada duty cycle 34.57 menghasilkan tegangan sebesar 13.9.]]>
