Abstract

The aim of this research was to propose an innovative method of controlling the speed of an induction motor (IM) using fuzzy logic, integrated with internet of things (IoT). To achieve this aim, fuzzy logic was used to increase the performance of IM in order to obtain stable speed and high system response even in the presence of disturbances. Moreover, fuzzy logic relied on rules that used linguistic variables, and its main advantage was simple yet highly accurate, enabling the system to be efficient for determining parameters compared to the time-consuming and inefficient trial-and-error method. In this research, IoT implementation used Blynk platform to control and monitor IM speed remotely. Additionally, the components used in this research included an inverter, gate driver, Arduino Mega 2560, and NodeMCU ESP8266. Pulse width modulation (PWM) was required to obtain rotational speed of the motor through MOSFET switching process. The gate driver amplified PWM signal from Arduino Mega 2560, allowing MOSFET to operate. As a result, IM achieved a stable speed, and the system response followed the reference using fuzzy logic. In addition to this process, the system could be controlled and monitored remotely. Finally, the control system was successful, and the results were presented to show the viability of the proposed method.

Abstract

The rapid advancement of digital image processing technology is expected to facilitate human life in various aspects of life. This study aims to detect and determine the distance of a barrier object based on the detection of lines emitted by a line laser light beam using the Matlab programming language with the pixel distance calculation method. The pixel distance calculation method is used to detect lines in an image that is processed by looking at the consistency of the laser lines. This study uses a box as an object to determine the presence of obstructions from an image captured by a camera. In this study, the parameters of distance, camera angle, and line laser angle are used. Research data collection was carried out in the afternoon in a closed room with a light intensity of 10 lux. An object can be said to be a barrier if in an image there is a laser line that is broken or not at the same pixel position. However, if in an image there are consistent lines or no line changes, then the image can be said to have no barriers. Based on the evaluation of the distance accuracy calculation with data collection, it can actually be concluded that the distance accuracy when taking data is above 85%.

Abstract

Solar panels are the main device of a solar power generation system that functions to convert sunlight energy into electrical energy. The purpose of this study is to make it easier for users to monitor the voltage and current values in the battery generated by solar panels via smartphones with applications that have been designed, to develop tools and applications to monitor and control Internet of Things-based solar panels using the NodeMCU microcontroller so that they can be accessed via internet. The tool that will be made requires the INA219 sensor which will become one with the NodeMCU. In this study, it was found that the monocrystalline solar panel with a power of 50WP only has a de-efficiency value of 0.138%. In INA219 sensor measurement data, it can be seen that this data has a success value of 99.75% and a fairly small error value of 0.25%. On the INA219 sensor, the current value read is 0.014 to 0.712 A. This can be seen on the Blynk serial monitor.

Abstract

Kecepatan motor induksi dapat diatur dengan mengubah tegangan input, jumlah kutub ataupun frekuensi yang diberikan pada motor. Mengatur kecepatan motor induksi dengan cara mengubah tegangan input dan jumlah kutub cukup sulit dilakukan. Oleh karena itu hal yang paling mudah dilakukan adalah dengan mengubah frekuensi input pada motor induksi. Salah satu cara mendapatkan nilai frekuensi yang dapat diubah – ubah adalah dengan menggunakan inverter. Inverter yang digunakan pada penelitian ini adalah diode clamped multilevel inverter. Untuk memudahkan dalam melakukan kontrol kecepatan dan monitoring motor induksi, digunakan sensor tegangan ZMPT101B dan sensor kecepatan Optocoupler serta aplikasi blynk sebagai media dari internet of things. Hasil pengujian menunjukkan jika rangkaian alat dapat bekerja dengan baik. Perubahan frekuensi yang dilakukan diode clamped multilevel inverter berhasil mengubah kecepatan putaran motor induksi dan kontrol serta monitoring menggunakan konsep internet of things dapat bekerja sesuai kebutuhan.
