Abstract

Robotics is a field of science that is developing rapidly, One of Robotic field is a wheeled robot whose sample application allows robots to explore automatically. But today, more research on the application of artificial intelligence in robot control is aimed at obtaining sophisticated kinematic control. In this final project, a wheeled robot will be designed with the ability to detect obstacles. As a control object is a robot tank that both wheels use a belt wheel and have a separate DC motor. A fuzzy logic controller functions to regulate the speed and direction of the robot's motion based on the input of the ultrasonic sensor. The design of robots based on the embedded microcontroller is designed using the C language. From the test results, that fuzzy logic can be embedded in the ATmega328 microcontroller control unit on Arduino Uno, so that a robotic motion can be avoided that can avoid obstacles properly. The closer the obstacle distance results in the sharpening direction of the robot and the more rigorous robot movement.

Abstract

Electrocardiograph (ECG) is a recorder of human heart signals with signal output on a monitor or graph paper. The ECG records the measurement of the electrical activity of the heart from the surface of the body by a set of electrodes that are installed in such a way that reflects the tapping point activity. The pattern of ECG output signals in one heartbeat produces a pattern with a peak point P, Q, R, S and T or QRS complex. ECG signal waveform results were analyzed using Learning Vector Quantization (LVQ) Artificial Neural Networks, and grouped into two classes, namely normal and abnormal heart patterns. The normal heart condition that is trained is a medically normal heart categorized as healthy as 10 data, while an abnormal heart (Heart, Coronary Heart, and Aortic Regurgutation) is 20 data. The LVQ method recognizes the input pattern based on the proximity of the two vectors, namely the vector of the input unit or neuron with the weight vector produced by each class. Online LVQ identification (using ECG) recorded from 25 direct trials resulted in 80% accuracy.

Abstract

One area of business that is in great demand today is the culinary field. The culinary field is very mushrooming because it deals with meeting basic human needs. Therefore service to digital needs to be a concern. The goal is to improve services with NFC (Near Field Communication) based on Android for ordering food and drinks. This research uses experimental research methods by applying NFC that is on smart phones as a way to bring the smart phone closer to the NFC tag that is already on each table. Message data entered on a mini PC computer (Raspberry Pi) as the server for the next as a booking order that will be ordered by the waiter. Simulation show that a system can read NFC tags and find out table numbers via a smart phone with a 100% success rate, remote reading of NFC tags by smart phones is 2.5 cm and the average time by the system is 1,12 seconds. Besides that, the system is also equipped with calculations for payments with 100% accuracy.

Abstract

Shopping Mall merupakan area pusat perbelanjaan yang besar dan memiliki sistem keamanan seperti sistem layanan informasi yang dapat dimanfaatkan oleh konsumen untuk mendapatkan informasi yang dibutuhkan. Penggunaan sistem layanan informasi pada area Shopping Mall bagi konsumen terkadang sangat tidak efektif. Hal ini dikarenakan konsumen membutuhkan waktu yang lama dalam mendapatkan informasi, dimana konsumen terlebih dahulu harus mencari lokasi tempat sistem layanan informasi tersebut. Hal ini menjadikan sistem keamanan pada Shopping Mall menjadi lemah. Indoor Positioning System (IPS) merupakan sistem yang dapat digunakan untuk mengetahui posisi pengguna melalui kekuatan sinyal Wi-Fi yang didapat dalam gedung. Pada penelitian ini, penulis membuat suatu aplikasi android yang dapat digunakan untuk mengetahui posisi konsumen pada area Shopping Mall tersebut.

Abstract

The tightness of one's activities sometimes makes people forget about security and comfort issues such as forgetting to lock the door, forgetting to turn off the lights or other electronic equipment so that it makes the house unsafe and also have an impact on energy waste. This research objective was to design a home security control system using Raspberry Pi connected to several electronic equipment, wifi, and internet communication networks. Remote control and monitoring using a smartphone. The test was carried out on ACS712 current sensor, PIR (Passive Infra Red) sensor, DHT22 temperature and humidity sensor, two lights and one webcam and buzzer. The test results show that the system that is designed can display information on current values, temperature, and humidity and also can control the condition of the house by turning on and off two lights with a 100% success rate. The PIR sensor can detect the movement of people at a maximum distance of 5.5 meters and the webcam manages to capture objects when motion is detected, the notification will automatically be sent to the owner's smartphone and the buzzer will be activated immediately.

Abstract

Braking Automation system is needed to make people do their job in braking while driving. This paper aims to design and construct an electromagnetic braking automatic system that able to make car stopped before colliding a barrier by applying of the Proportional Integral Derivative (PID) method. To find out how the effective utilization of PID control on electromagnetic braking automatic will be compared with the results of braking without using PID. Determination tuning result of controller PID parameter obtained by using the trial and error methods and obtained the PID parameter values that suitable are Kp = 2.98, Ki = 0.104 and Kd = 1.35. The ultrasonic sensor used as detection the distance to a barrier. From the testing results of electromagnetic braking system with PID control more effective than with the electromagnetic braking system without PID because it can be seen from the side cessation of the car approaching set point, the results of the electromagnetic braking with PID control better than the electromagnetic braking without PID control.
