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

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

Penggunaan sumber daya minyak bumi dan secara terus-menerus dapat menyebabkan cadangan sumber daya tersebut semakin menipis. Oleh karena itu, sesuai dengan arahan Kementerian Energi dan Sumber Daya Mineral (ESDM) diperlukan suatu teknologi untuk meningkatkan elektrifikasi dan konsumsi listrik terutama dalam kebutuhan rumah tangga,salah satunya kompor induksi. Kompor induksi sudah mulai banyak digunakan, tetapi bisa dikatakan masih belum fleksibel dan kompatibel. Sehingga, diperlukan kompor induksi yang dapat digunakan kapan pun dan di mana pun. Diperlukannya sebuah kompor induksi yang demikian, dikarenakan pentingnya para bayi untuk mengonsumsi Makanan Pendamping Air Susu Ibu (MPASI) pada kondisi yang konstan dan stabil terhadap suhu di lingkungan sekitar yang sangat bervariasi sehingga nutrisi bayi dapat terjaga dan terpenuhi dengan baik. Sistem ini dirancang menggunakan input tegangan 220 VAC yang kemudian diturunkan menjadi 36 VAC menggunakan transformator dengan tujuan agar arus pada sistem yang nantinya masuk ke inverter tidak terlalu besar. Terdapat lilitan induktor pada rangkaian resonansi seri yang menghasilkan medan listrik dengan frekuensi resonansi 40 kHz dan menginduksi logam sehingga menghasilkan panas pada logam. Fuzzy Logic Controller (FLC) digunakan untuk mengontrol kecepatan menuju set point suhu MPASI.

Abstract

In this research, designed an overvoltage and undervoltage fault detector based on the Internet of Things (IoT), which aims to monitor the quality of electrical voltage in detecting overvoltage / undervoltage faults that change instantly with real-time monitoring. This system detects voltage disturbances using the PZEM-004t sensor by considering PLN standards. The overvoltage is above +5% normal voltage and for undervoltage below -10% normal voltage. Voltage disturbances are injected through the transformer configuration to generate overvoltage / undervoltage instantly. Furthermore, the voltage that has been read by the sensor is sent to the Blynk platform as a monitoring system. The transformer configuration is simulated first, with an overvoltage result is 251.8 V and an undervoltage is 110.6 V. In the results of the hardware transformer configuration test, the overvoltage injection is 253 V and the undervoltage is 117.3 V. The data displayed by the monitoring system is compared with the Fluke 43B measuring instrument to be calibrated, with an average error of 1.2%. Monitoring data can be accessed via gadgets. So that preventive actions and analysis can be carried out to reduce the risk of losses due to voltage disturbances.

Abstract

Kampung Seni Grajen utilizes this wood dust waste to create high-value paintings through a manual roasting process, which requires significant time and intensive supervision. This study aims to develop an electric stove based on fuzzy logic to improve the efficiency of the wood dust roasting process. The electric stove employs a Band Heater as a heating element, controlled by an AC-AC Controller and fuzzy logic to regulate the temperature automatically. The system is also equipped with an agitator to ensure even heat distribution. Testing was conducted using both open-loop and closed-loop methods. In the open-loop testing, the input voltage directly affected the temperature, but the temperature increase was not always linear. The closed-loop testing demonstrated that the system could maintain a stable temperature in the range of 84°C to 87°C, with an error rate of 2.38%, despite slight discrepancies due to environmental factors or sensor tolerances. The roasting results are used to make Grajen paintings

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.

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.
