Abstract

This paper presents a pair of portable wireless nodes for a smart agricultural system to control and monitor the agricultural parameters based on Internet of Things (IoT). This system utilizes low-cost wireless communication through an nRF24L01 module between the sensor node and the controller node. The sensor node is placed on the agricultural area with a Li-Ion battery as a power supply, while the controller node is placed at the control and monitoring station. On the sensor node, there is a YL-69 soil moisture sensor and DS18B20 temperature sensor, while in the controller node there is a relay that can set watering on/off condition. In the controller node, there is also an ESP8266 WiFi module that serves to send data to the internet cloud for user monitoring. Both hardware nodes are built in small and portable size. The experimental result shows that the sensor node can transmit soil moisture and temperature data via RF wireless communication to the controller node. Watering is done automatically based on the condition of sensor values. In addition, this system can also be monitored through a website interface, so the users can easily find out the condition of their plant as long as there is internet access.

Abstract

Robot arm is often used in industry with various tasks, one of which is a pick and place. Rapid prototyping of robot arms is needed to facilitate the development of many industrial tasks, especially on a laboratory scale. This study aims to design a small-scale three degree of freedom (3-DoF) robot arm for pick and place mission using the inverse kinematics method. The mechanical robotic arm system is designed using Solidworks with four servo motors as the actuator. Arduino Mega 2560 is used as a microcontroller in which the inverse kinematic method is embedded. This method is used to move the robot based on the coordinates of the destination pick and place. The test results show that the robot arm can carry out the pick and place mission according to the target coordinates given with the largest average error of about 5 cm. While the error generated between the calculation and computation results is around 3%.

Abstract

In hydroponic cultivation sites, pH control is still carried manually by checking the pH level with a pH meter and providing a pH balancing liquid manually. This study aims to design an automatic pH control system in the Deep Flow Technique (DFT) hydroponic system that uses the Internet of Things (IoT) based Fuzzy Logic Controller (FLC). The SKU SEN0161 sensor detects the pH value as FLC inputs in an error value and its changes. These inputs are processed using Mamdani FLC embedded in the Arduino Mega 2560 microcontroller. The FLC produces an output in a pH liquid feeding duration using the peristaltic pump. The results showed that FLC could maintain the pH value according to the set point with a settling time of less than 50 seconds, both with disturbance by adding pH liquid and without disturbance. The pH value can also be displayed on the website interface system as a monitoring system.

Abstract

Pada sistem hidroponik deep flow technique (DFT), setiap umur dan jenis tanaman yang ditanam memerlukan total dissolved solids (TDS) dengan satuan ppm yang berbeda serta kegagalan tanaman dalam bertumbuh dapat terjadi jika nilai TDS tidak terpantau dengan baik. Tujuan dalam penelitian ini untuk membuat sistem kendali nilai TDS dengan metode fuzzy logic agar nilai TDS sesuai dengan kondisi tanaman yang ditanam serta membuat sistem pemantau nilai TDS dengan memanfaatkan Internet of Things (IoT) agar nilai TDS dapat terpantau dengan baik. Sistem ini menggunakan nilai error dan delta error yang didapat dari selisih nilai setpoint dengan sensor TDS SKU:SEN0244 sebagai masukan fuzzy logic. Keluaran sistem berupa durasi ON dan OFF relay yang terhubung dengan pompa air 12 VDC. Nilai setpoint dan bacaan sensor akan ditampilkan pada LCD serta ditampilkan juga pada aplikasi Android Blynk dengan menggunakan module WiFi NodeMCU ESP8266 sebagai wireless. Hasil pengujian dari sistem yang dirancang yaitu sensor TDS yang digunakan memiliki rata-rata error sebesar 0,165%. Pengendalian yang dirancang mampu menghasilkan nilai integral absolute error (IAE) terkecil sebesar 1119 pada setpoint 800 ppm dan integral time absolute error (ITAE) terkecil sebesar 4200 pada setpoint 1000 ppm.

Abstract

Kendali posisi motor DC sangat diperlukan dalam berbagai sistem dinamik. Karaketristik kekokohan pengendalian menjadi salah satu hal yang harus dipertimbangkan dalam pengendalian posisi motor DC. Makalah ini bertujuan untuk mengusulkan metode pengendalian posisi motor DC menggunakan kendali Interval Type 2 Fuzzy Logic (IT2FL). Berbeda dengan pengendali logika fuzzy tipe 1, pengendali ini memiliki fungsi keanggotaan dengan Footprint of Uncertainty (FoU) di setiap variabel linguistik. Kelebihan inilah yang menyebabkan kendali logika fuzzy tipe 2 memiliki karakteristik kekokohan terhadap ketidakpastian parameter sistem. Penelitian ini menggunakan simulasi Matlab/Simulink untuk menunjukkan respon pengendalian dengan penambahan sinyal derau dan dua skenario FoU. Hasil simulasi menunjukkan bahwa pengendali IT2FL menghasilkan performa lebih baik dibandingkan pengendali logika fuzzy tipe 1 dalam mengatasi derau pengukuran. Pada pengendali IT2FL, FoU 0,2 menghasilkan integral error yang lebih kecil dibandingkan FoU 0,1 dengan selisih terkecil sebesar 0,001. Position control of DC motor is indispensable in various dynamic systems. Control robustness characteristics are one of the things that must be considered in controlling the position of a DC motor. This paper aims to propose a DC motor position control method using an Interval Type 2 Fuzzy Logic (IT2FL) controller. Unlike the type 1 fuzzy logic controller, this controller has a membership function with a Footprint of Uncertainty (FoU) in each linguistic variable. The benefits of it cause the type 2 fuzzy logic control to have robust characteristics against the uncertainty of system parameters. This study uses a Matlab / Simulink simulation to show the control response with the addition of a noise signal and two FoU scenarios. The simulation results show that the IT2FL controller produces better performance than the type 1 fuzzy logic controller in overcoming measurement noise. In the IT2FL controller, FoU 0.2 produces an integral error that is smaller than FoU 0.1 with the smallest difference of 0.001.

Abstract

Process control is needed in various types of industries for production. The controlled process variables can be temperature, flow, pressure, and level. For this reason, an automatic control system with the right method is needed to produce quality products. This study aims to design and implement a steam pressure control system on a prototype heating tank using PID controller based on PLC. The pressure in the heating tank will be controlled to a set point of 10 kPa with a maximum steady-state error of 3%. PID control is designed using the Ziegler Nichols method which is then implemented on the PLC Omron CP1H with an MPX5500DP sensor to detect pressure. The results of the research obtained are that the PI controller can produce a better response when compared to the P and PID controllers. PI controller with parameters Kp = 1.23, Ti = 860, and Td = 0 can produce a response with a rise time of about 300 seconds and a steady-state error of 3.3%.

Abstract

Air pollution is one of problems causing global warming that is currently taking a place. Several air quality monitoring devices usually located at the city center are only limited to display data at one point. Therefore, a mobile device to monitor air quality is needed so as to enable the monitoring in several points. This paper aims to design an air quality monitoring system based on quadrotor Unmanned Aerial Vehicle (UAV) and Internet-of-Things (IoT) technology. The sensor system is designed to detect CO, CO2, air quality, and temperature variables. This sensor systems was then integrated with quadrotor in order to make the monitoring process can be carried out at various points. Quadrotor was designed using Ardupilot Mega (APM) 2.6 as the flight controler. Measurement data from system sensor was transmitted wirelessly using internet network via Wi-Fi module. Based on the test results, the sensor system was able to detect concentration of several test gas and was linear to the output voltage. Quadrotor orientation parameters at takeoff produced transient responses in less than 1 second. The air pollution sensor parameter data could also be displayed every 10 seconds on the ThingSpeak and ThingView interfaces, and could be mapped based on the data retrieval coordinates.

Abstract

Saat ini penelitian terkait kendaraan listrik, khususnya mobil listrik, masih terus dilakukan dalam upaya mengurangi tingkat emisi dari kendaraan bermotor. Beberapa permasalahan yang muncul diantaranya adalah terbatasannya penggunaan baterai, terbatasnya jarak tempuh, dan kesiapan infrastruktur. Dalam skala laboratorium dan pendidikan tinggi, penelitian tentang mobil listrik akan sulit dilakukan jika tidak menggunakan sebuah purwarupa dalam skala kecil. Sebuah simulator mobil listrik berbasis motor arus searah (motor DC) yang saling terhubung sumbu putarnya dapat dirancang untuk mempermudah pengamatan dalam penelitian mobil listrik. Dengan menggunakan asumsi-asumsi yang telah ditentukan, perilaku mobil listrik sebenarnya dapat disimulasikan dengan menggunakan simulator ini. Makalah ini akan mengulas desain dan implementasi simulator mobil listrik berbasis motor arus searah yang telah dirancang dan dikembangkan beberapa tahun terakhir ini. Pemodelan matematis, perancangan perangkat keras, hingga algoritma pengoperasian akan dibahas untuk menunjukkan bahwa simulator ini dapat dimanfaatkan sebagai media penelitian terkait mobil listrik.
