Penggunaan beban listrik induktif dapat menurunkan nilai factor daya pada listrik, faktor daya yang baik adalah antara 0,85 sampai 1. Oleh karena itu perlu ditambahkan kompensasi daya reaktif yang timbul dari beban listrik induktif untuk menghindari kerugian yang timbul akibat kekurangan nilai faktor daya. Dengan menggunakan kapasitor yang dipasang secara paralel bertujuan untuk meningkatkan nilai factor daya. Dengan sistem pemantauan jarak jauh menggunakan smartphone android dan Alat ini menggunakan ESP32 sebagai mikrokontroler dan sensor PZEM 004T untuk mengukur besaran listrik. Hasil pengukuran ditampilkan pada LCD dan smartphone Android yang dikirimkan melalui internet. Modul relai digunakan sebagai sakelar pemilihan kapasitor otomatis untuk peningkatan faktor daya. Ditemukan bahwa hasil tes pembacaan sensor memiliki akurasi hingga 99,7%. Untuk peningkatan efisiensi, nilai faktor daya dapat mencapai 95%, dan peningkatan tertinggi adalah 35,8%.

The first problem is the presence of crowds during practicum report collection that have their dangers, specifically during the Covid-19 pandemic. Another problem is the absence of laboratory assistants in the electrical engineering laboratory when there are students who will collect reports. A tool that can receive practicum reports was made from these problems, and it can be monitored remotely by a laboratory assistant. By putting an RFID card to the RFID sensor on the box so that the solenoid can open the box door and the student can put the report into the box. At the same time, ESP32-CAM takes pictures of students collecting the report. Then, notification in the form of photos and student information will be sent to the laboratory assistant through the Telegram application. After the report is placed into the box, the UV Sterilizer will turn on to disinfect the report. The expectation of making this tool is to facilitate the collecting report process of practicum results and reduce the crowd in the laboratory.

Still, in dire need of electricity as a life support, the Pico hydro Power Plant (PLTPH) is a cheap alternative, the advantage of the water turbine is that it is environmentally friendly because it does not disturb the water ecosystem in the rivers that exist in every rural area. The method used by the author is to design a tool to measure the rotation of the generator, the power that comes out of the generator, and others. where the flow of water passes through the turbine lattice so that it moves the turbine shaft and produces electrical energy through a generator then electricity can be stored in the battery and can be used for the appropriate working voltage of 12VDC. In the charging process, reading is also carried out by the sensor, to detect the voltage and current which is then processed by the NodeMCU Esp 32 and then transmitted into the Google sheet.

The automatic roof control system in the drying room is the best way to help the process of drying clothes in the rainy season. In this study, roof automation was developed using rain sensors and LDR as light detectors. NodeMCU esp3266 is also used so that the device can be controlled remotely with the Internet of Things system. The way this tool works is when the sun is hot the roof will open and when it rains the roof will close automatically, the heater and fan turn on simultaneously when the roof closes. The results of this study are the tool can detect rain and light then the heater and fan can work when the tool closes the roof with a maximum duration of 60 minutes. This tool can also operate remotely with the farthest range at 21 km.

In previous studies, the fuel cell circuit was judgedto be quite different by integration with a standalone photovoltaic system, and in thisstudy, observations were made on aspects of power quality such as voltage, current, andpower for the two energy storage systems. The research method is using simulation as themedium with several self-definition aspects on photovoltaic, fuel cell, battery, andsupercapacitor, also with their parameters. The result shows that on the battery, the fuelcell integration has no particular effect since the battery is the main storage, and thevoltage and current had minor perturbation. While in a supercapacitor, majorperturbation from the system had been absorbed due to the f...

One hectare of paddy land can produce 7.71 tons during normal weather, but currently only produces 6.9 tons per hectare. Three farmers’ groups in Malang Regency (2018), are of the opinion that the current weather greatly influences crop failure. Weather prediction used so far using conventional benchmarks for planting, is no longer relevant to current reality. These estimates are often incorrect, resulting in crop failures, which have an impact on the farmer’s economy. This study aims to make the application of weather prediction systems and recommendations for suitable planting varieties based on data on temperature, humidity, time of sun exposure, wind speed, and rainfall using Backpropagation ANN method. Data used for Karangploso District weather prediction from 2009-2018. While the variables used in the app...

Energy audit activities can analyse and find energy-saving opportunities from energy use. This study developed a prototype of a wireless electrical energy monitoring system on a laboratory scale to monitor the use of electrical energy from both electrical equipment using a microcontroller as a sensor node. These nodes have installed several sensors, namely the current sensor, humidity sensor, temperature sensor and light sensor. The protocol used in communication between nodes and servers is the HTTP protocol in the Internet of Things design that can communicate using internet network intermediaries. Data on the server can be monitored in real time using the application on the client side.

The development of this fuzzy logic by widening the foot of the membership function as interval fuzzy type 2, fuzzy signature or carried out a hybrid between fuzzy logic and other artificial intelligence systems or a hybrid algorithm has also got quite good results. At this time, a multilevel fuzzy logic method is proposed. This multilevel Fuzzy Logic is interesting behind the input of a process in fuzzy logic, which is the output of the previous fuzzy logic or the output of a fuzzy logic analysis is input into the next stage of fuzzy logic. This multilevel fuzzy logic can be done up to several levels of depth according to the variables to be analysed. If the final analysis has the equation X(i) + Y(i) = Z(i), then the value of X (i) can be the result of A(i-1), where A(i-1) is the result of the Fuzzy Logic B(i-1) + C(i-1). by performing multilevel fuzzy logic is ex...

Bahaya yang ditimbulkan antara lain produktivitas dan pertumbuhan ayam menjadi lambat. Oleh karena itu, dari permasalahan tersebut diperlukan sebuah sistem monitoring pengendalian gas amonia serta pembersihan kotoran secara otomatis. Sensor MQ135 digunakan untuk mengetahui kadar gas amonia dan DHT11 untuk membaca suhu kandang. Jika sensor MQ-135 membaca nilai konsentrasi gas amonia (>=20ppm) maka akan menghidupkan kipas dc selama beberapa detik sampai nilai amonia dibawah 20 ppm, jika gas amonia melebihi atau sama dengan 30ppm maka akan menghidupkan kipas dc dan menghidupkan pompa air sebagai pembersihan kotoran pada kandang selama beberapa detik sampai kotoran bersih.
