Abstract

Monitoring for voltage and current in a three-phase induction motor that is widely used in industry needs to be carried out continuously to ensure that motor performance remains good. Utilizing the Internet of Things (IoT) can help carry out this monitoring task to minimize the existence of human error factors. Design and implementation of a system is needed to monitor voltage and current in a three phase induction motor using the IoT concept so that monitoring can be done anytime and anywhere as long as it is connected to the internet. This system design consists of hardware and software that works to monitor the voltage and current that comes from a three-phase induction motor. The hardware part consists of the NodeMCU+ESP8266 module, 16x2+I2C LCD module, ACS712 current sensor module, AC voltage sensor module, CD4051 analog IC multiplexer, and power supply. The software part is a program algorithm that contains a flow of voltage and current readings to be displayed on IoT services named Thingspeak. The appearance of the Thingspeak application is designed to present data readings of three-phase voltage sensors and readings of three-phase current sensors. The results of the research show that the system designed has been implemented to monitor voltage and current in an three-phase induction motor based on IoT. The data displayed in Thingspeak consists of three phase AC voltage and three phase AC current. The test results show the difference between the data on Thingspeak with a measuring device which is 1% for phase R voltage, 2% for S phase voltage, 1% for phase T voltage, 37% for phase R current, 7% for S phase current, and 13% for phase T current.

Abstract

A smart home security system consists of various sensors and recorders to automatically provide data on the conditions of a house. Home electronic equipment may be controlled from distant places using the internet of things technology and speech recognition. This research aims to develop a smart home security system by monitoring fire hazards and theft. It helps also control electronic equipment using voice commands that is useful especially for the disabled. The system design consists of hardware, software, and application design. Hardware design uses ESP8266, Arduino Mega 2560, MicroSD Card module, VC0706 serial camera, DHT22, magnetic door switch, PIR HC SR501, and Google Assistant device. Software design uses Arduino IDE for programming Arduino Mega and ESP8266. Applications used in the design are Adafruit.io, Thingspeak, and IFTTT (If This Then That). Voice commands control home electronic devices (lights), while fire and theft are monitored through the use of sensors and cameras. The system test shows that voice command can control lights on and off at an accuracy of 88%. Temperature and humidity sensors acquire data and send them to Thingspeak application for online fire monitoring. Sensors to detect intruders in the form of door switch and PIR work well and automatically activate cameras that capture objects to store in a MicroSD card.

Abstract

Pemantauan tegangan dan arus pada motor DC dapat dilakukan dengan berbagai cara, salah satunya adalah dengan menggunakan konsep Internet of Things (IoT) sehingga pemantauan dapat dilakukan kapanpun dan dimanapun. Pemantauan menggunakan konsep IoT ini juga dapat dilakukan secara real time menggunakan perangkat PC, laptop, dan smartphone selama perangkat tersebut tetap terhubung dengan jaringan internet. Penelitian ini bertujuan untuk melakukan desain dan implementasi alat untuk memantau tegangan dan arus pada motor DC dengan menggunakan konsep Internet of Things (IoT). Sistem dirancang menggunakan modul sensor tegangan dan arus DC yang dihubungkan ke sebuah multiplexer analog yang keluarannya akan dihubungkan ke I/O analog pada NodeMCU yang sudah dilengkapi dengan modul IoT berupa ESP8266. Data tegangan dan arus hasil pembacaan sensor ini, selanjutnya akan diolah oleh NodeMCU untuk di tampilkan pada sebuah LCD 2x16 dan juga di publikasi ke sebuah broker Thingspeak agar data tersebut dapat disimpan dan di unduh dalam format CSV. Hasil dari penelitian ini menunjukkan bahwa desain dan implementasi dari alat pemantau tegangan dan arus pada motor DC menggunakan konsep IoT ini sudah dapat menampilkan hasil berupa data tegangan dan arus yang sesuai antara yang tampil pada LCD dan juga yang terpublikasi pada Thingspeak secara real time. Hasil pengujian menunjukkan bahwa terdapat selisih sebesar 1% antara data tegangan dari voltmeter DC dengan hasil pembacaan tegangan pada alat, dan selisih sebesar 2% data arus amperemeter DC dengan hasil pembacaan arus pada alat. Hasil data yang ditampilkan pada Thingspeak terdapat jeda waktu yang lebih lambat dari data yang ditampilkan pada LCD

Abstract

Sinyal analog berupa tegangan antara 0 – 5V tidak dapat dihasilkan oleh mikrokontroler arduino, sehingga diperlukan rangkaian eksternal untuk menghasilkan sinyal tersebut. Rangkaian eksternal Emitter Follower (EF) mengunakan transistor PNP dapat digunakan untuk mengubah sinyal PWM dengan lebar pulsa tertentu ke dalam sinyal tegangan listrik, sehingga konversi digital ke analog (DAC) di mikrokontroler arduino memungkinkan dilakukan.Penelitian menggunakan metode eksperimen. Pin out 6 mikrokontroler arduino nano di fungsikan sebagai Pulse Wide Modulation (PWM) dengan frekuensi 1000 Hz dan terhubung ke rangkaian EF. Perintah numerik lebar pulsa (duty cycle) tertentu dari sinyal PWM di mikrokontroler arduino akan dilakukan konversi dirangkaian EF untuk menghasilkan keluaran (output) sinyal analog berupa tegangan listrik. Hasil dari penelitian ini, dengan mengubah lebar pulsa PWM dari 0 - 100% di pin out 6 mikrokontroler arduino dapat mengubah tegangan output rangkaian EF dari 0,68 - 5V. output dari rangkaian tersebut dapat dimanfaatkan sebagai sinyal tegangan referensi.

Abstract

Corrosion is a property of a material that causes the material to lose its weight and strength where this corrosion property factor can occur because it is caused by environmental conditions that result in the effect of corrosion on the material. In the world of aviation, corrosion is a matter of great concern to aircraft technicians because if you ignore this corrosion, it will greatly disrupt the activities of the aircraft. And on the plane most use aluminum alloy material, especially on the leading edge the material is made of aluminum alloy. To find out the corrosion that occurs on the aircraft, we can do material testing such as micro photo testing and weight loss in order to see how fast the corrosion rate is on the aluminum material. Therefore, in order to slow down the corrosion rate on the aluminum alloy material, a coating using a mixed inhibitor layer, namely potassium chromate and sodium chromate, will be carried out to slow down the corrosion rate that occurs.
