Abstract

Penelitian mengenai elektronika daya semakin berkembang, salah satunya yaitu Z-source inverter sebagai alternatif konsep konversi daya guna meningkatkan tegangan tanpa adanya penambahan topologi peningkat tegangan (single stage) sebelum dihubungkan ke inverter. Penambahan topologi peningkat tegangan menimbulkan rugi-rugi switcing yang cukup besar yang dapat menurunkan nilai efisiensi.  Oleh karena itu, diperlukan desain topologi yang dapat beroperasi sebagai boost converter serta mengurangi rugi-rugi tegangan.  Z-source Inverter merupakan perkembangan dari Voltage Source Inverter dengan penambahan rangakain sumber impedansi dan kontrol penyalaan menggunakan Maximum Boost Control. Maximum Boost Control merupakan sinusoidal PWM (SPWM) yang dimodifikasi dengan menambahkan kondisi Shoot Through Zero State serta meminimalkan nilai index modulation (M) dan memaksimalkan nilai Boost (B) dengan faktor peningkat tegangan (B) sebesar 3.27 kali untuk suplai motor induksi 1 fasa. Dimana dari tegangan masukan inverter DC 96 Volt langsung dapat dinaikan menjadi tegangan AC 223.9 Volt hanya dengan satu kali topologi dengan efisiensi mencapai 90%.

Abstract

A magnetic stirrer is a laboratory tool that is used to stir or mix a solution with another solution so that the solution is heterogeneous. Technology and science have now progressed, so in this study, a microcontroller-based magnetic stirrer was designed. This tool is designed with digital speed and time settings, with digital technology, it is hoped that the data reading error of the speed and time of mixing samples can be minimized, efficient in time, relatively easier to use, and produces a homogeneous solution. Based on the results of the analysis that has been carried out by a microcontroller-based magnetic stirrer in a solution with low viscosity from mixing water and syrup, it requires mixing time for 1 minute with low, medium, and high speeds. For a solution with a higher viscosity using water and special grade syrup, it takes 5 minutes at medium and high speeds. To mix water with salt and water with sugar takes 10 minutes at high speed.

Abstract

Abstract. The use of increasingly sophisticated technology for health workers certainly requires proper and regular care. This technology is essential in puskesmas services, such as a circuit on a dental examination board, a sensor on a lighting lamp, a stethoscope, and an ECG. Medical devices that have a good level of reliability will provide good service quality. Apart from being a form of treatment for medical devices at the puskesmas, this service is also training for technicians and health workers for medical device maintenance. This, of course, will increase knowledge and skills in managing, maintaining, and repairing medical devices at puskesmas. This activity will further support puskesmas services, especially during the Covid-19 pandemic. From the actions that have been carried out, it has been able to improve and overcome several problems with several medical devices, such as dental units, ECGs, headlamps, and otoscopes. This activity indirectly provides knowledge and learning in the form of good experiences and adds insight into the operation of medical devices that are used so that they are always active, accurate, and can help health activities at Banjarangkan II Klungkung Health Center. --- Pemanfaatan teknologi tenaga kesehatan yang semakin canggih tentu saja memerlukan adanya perawatan secara baik dan teratur. Teknolgi ini merupakan satu elemen penting dalam pelayanan di puskesmas, seperti rangkaian pada board pemeriksaan gigi, sensor pada lampu pencahayaan, stetoskop, dan juga ECG . Peralatan kesehatan yang memiliki tingkat keandalan yang baik akan memberikan mutu pelayanan yang baik. Pengabdian ini selain sebagai bentuk perawatan alat kesehatan di puskesmas juga merupakan pelatihan perawatan peralatan medis untuk teknisi dan tenaga kesehatan. Hal ini tentu saja akan meningkatkan pengetahuan dan keterampilan dalam mengelola, memelihara dan memperbaiki peralatan kesehatan di puskesmas. Kegiatan ini akan bisa lebih mendukung dalam pelayanan puskesmas terutama di masa pandemi Covid-19. Dari kegiatan yang telah dilakukan telah dapat melakukan perbaikan dan mengatasi beberapa permasalahan pada beberapa alat kesehatan, seperti dental unit, ECG, head lamp, dan otoskop. Kegiatan ini secara tidak langsung memberikan ilmu dan pelajaran berupa pengalaman yang baik, serta menambah wawasan tentang operasional alat medis yang digunakan agar selalu aktif, akurat, dan tentunya dapat membantu kegiatan medis di Puskesmas Banjarangkan II Klungkung.

Abstract

In the maintenance of Measuring and Limiting Devices (APP) by replacing the kWh Meter on the old kWh meter, as well as P2TL efforts to examine customers who have the potential to commit violations or lack of billing in adjusting electricity rates. In this operation an error / deviation check will be performed on the kWh meter to determine the feasibility of the kWh meter. So far, the measurement of deviation on the kWh Meter 3 Phase is done manually so that it is considered less effective. With this deviation gauge kwh meter 3 phase measurement, meter change officers and P2TL field officers will be able to help in measuring the deviation in the 3 phase kWh meter. This tool reads the power of the kWh meter through the display of the led impulse indicator, then compares it with the power measurement using the metering module at the same time so that the deviation can be detected whether more or less from the meter class, because the measurement standards are based on the meter class. The results obtained from testing on a kWh meter with a grade of 0.5, obtained a deviation of less than 0.5 percent, which means the kWh meter is good because it is still awake in its class according to SPLN No.96 of 1993.Keywords: Deviation, Kwh Meter, Maintaining APP, P2TL

Abstract

Background: One type of bird that is widely bred and maintained is the turtledove. At turtledove breeding, bird cage maintenance is still done manually for cage lighting, feeding and drinking. Manual maintenance of the cage will make it difficult for farmers who have a fairly busy schedule or often leave the house. Aim: For that reason, the authors decided to make a Smart Bird Cage. Method: In this study, the authors used STM32F4 Discovery and ESP8266 as control centers via smartphones. The sensors that will be used are the temperature sensor and the Light Dependent Sensor (LDR). The outputs are 5 volt dc motor, 5V dc pump motor, buzzer and exhaust fan using on/off control with internet of things (IoT). While the control system for heating the cage uses the PWM control method on the AC module control for the brightness level of incandescent lamps. Findings: The results of this study are the temperature in the bird cage is controlled with a heating lamp that turns on when the temperature is below 30 oC and with the IoT system used by farmers, they do not have to worry about managing bird cage consumption when outside the city.

Abstract

Transformer is a very important thing for distributing electricity. One of the troubles that happen to transformer is overload which can shorten their life or worse case it can cause an explosion. Up until now, PLN Corporation still doesn’t have mitigation alerts for overload. Load monitoring is still done manually along with inputting data on the web. It can cause false inputting of data due to human error. So, this research was made that can be monitored on the web and shown as a diagram with real-time parameters. This research can also be moved to its place because it’s portable. This research uses a current sensor and voltage sensor also GPS which is processed by a microcontroller and then the result is shown in LCD and monitoring web by ESP8266. Hopefully, this research can help PLN mitigate overload and reduce human error, remembering that substation transformer costs a lot. The result of the test shows that this system could read voltage and current values with average sensitivity 0,1803% and 1,15%. Besides, it has GPS to detect location when it moves place and it has high accurate.
