Abstract

Atrial fibrillation is a type of arrhythmia that occurs due to electrical breakdown from the atria so that blood cannot be pumped to the ventricles at the right time. This condition can lead to other complications, such as stroke, palpitations, cardiomyopathy and heart failure. The detection can be done using an electrocardiograph (ECG), holter monitor or electrophysiology, but this action takes a lot of time and money. Based on this, research was carried out to detect Atrial Fibrillation as soon as possible by building a system consisting of sensor AD8232, Arduino Uno and 16x2 LCD. The ECG signal will be acquired by the AD8232 sensor and processed by Arduino Uno to obtain feature values. The features used are the average and the median value of the QRS gradient and interval. The Artificial Neural Network (ANN) method is used as a classifier of these features with 2 conditions, “Normal” and “FA”. A total of 60 datasets were used, 40 of which were used as training data in the ANN training phase with backpropagation algorithm and 20 were used as testing data. From the BPM test carried out by comparing the sensor acquisition value and the manual calculation value, it was found that the accuracy of the sensor in acquiring the ECG signal was 94,55%. Then from the 20 tested data, the classification accuracy of the ANN method is 90% with an average calculation time of 32,09 ms.

Abstract

The heart is a vital organ that pumps blood throughout the body. A healthy heart beats neither too fast nor too slow, normally 60-100 times per minute. A heart that beats too fast up to 120-300 times a minute is called tachycardia. Ventricular tachycardia (VT) is a tachycardia that occurs in the ventricles if it lasts for a long time, can lead to congestive heart failure and death. Deaths caused by heart and blood vessels are in the highest rank in the category of non-communicable diseases, based on The Institute for Health Metrics and Evaluation (IHME). To prevent an increase in deaths from heart disease, the public is expected to be vigilant by checking their heart health from an early age. Cardiac examinations can only be done at health care service, therefore the aim of this study is to build a system that can detect VT that can be done alone anywhere. To build the system, the AD8232 module is used as a signal conditioner and Arduino Uno as a microcontroller. VT heart defects can be seen from the shape of the QRS signal and the rate of the heartbeat. The parameters to be used are the RR interval and the area under QRS. The classification method uses k-NN because this method is suitable if only a few parameters and data are used. From the research results obtained 90,47% accuracy for k = 3 and k = 5, 95,23% for k = 7.

Abstract

Myocardial Ischemia is a condition occurs when the blood flow to the heart is reduced, making the heart muscle lack of oxygen supply. The reduced blood flow occurs due to blockage inside the coronary arteries which could be the build-up of cholesterol or the clotting of the blood. The blockage could build-up even more from time to time, blocking the blood flow entirely and making the person with the condition more prone to a heart attack. Commonly, diagnosing Myocardial Ischemia is done by medical professionals at the hospital. AD8232 sensor kit and Arduino Uno Microcontroller are used to detect Myocardial Ischemia. The detection of heart condition is based on the slope of ST-segment and the peak of T wave that will be classified by Support Vector Machine classifier into either Myocardial Ischemia or Normal class. As many as 40 data were used to train the system and as many as 20 data were used to test the system. Sensor accuracy test shows sensor's accuracy of 95.56%. Test of SVM computation time gives a result of 3912.30 ms for average training time and 0.061 ms for average testing time. The accuracy of SVM classification tested on 20 data gives an accuracy rate of 85%.

Abstract

Urine produced by each person may vary based on its physiological. It was happened by some reason like daily diet, gender, condition of exrectory system, and so on. These factor may lead physiological change of urine like color and turibidity. That is why urin often used to determine a person's health condition. In other side doing traditional urine analysis error often occurs because it only rely on analyzer sight. Analysis of a person's condition through urine physical conditions is also very much needed in the operation process and it is not possible if periodic analysis is carried out continuously during the operation. Therefore we need a tool that can perform automatic analysis to minimize errors in analysis and taking patient handling actions. This study uses the TCS3200 sensor to extract features in the form of color and an IR Proximity sensor for urine fluid turbidity. The two features will be processed by Arduino Uno to carry out the classification process. The urine will be divided into three classes, namely: Normal Urine, Blood Urine, Pus Urine. The classification process will use the K-Nearest Neighbor method with varying K values ​​starting from K = 3, K = 5, and K = 7. The system was able to recognize urine with an accuracy of 86.7% then 86.7% and 80% respectively

Abstract

COVID-19 is a disease caused by the corona virus and it has caused a global pandemic since December 2019. The use of masks is highly recommended to stop the spread of the corona virus, especially in closed rooms with many people inside, such as the classrooms and the office spaces. Detection of people with mask to access door based on the ratio of face Bounding Box and Roundness using Naive Bayes on Raspberry Pi is used to ensure people wearing masks who want to enter classrooms and office spaces. Webcam is used to capture images of people who want to enter. The image is processed and classified on the Raspberry Pi 4. Image processing begins with converting RGB to YCbCr and performing the morphological dilation, the morphological opening, and the morphological closing of morphology. Image processing aims to segment the human faces and remove their backgrounds. Human facial features were extracted using the ratio of Bounding Box and Roundness analysis which aims to determine the detected human face. The method for classifying faces is the Naive Bayes method. The solenoid lock opens when the classification result uses a mask, and it will be locked when the classification result does not use a mask. In the process of testing the Naive Bayes model using 60 data, the highest accuracy is 90%. To prove the accuracy of the Naive Bayes model, a test was carried out by inputting images directly into the system at 5 different distances, namely at 0.5 meters, 1 meter, 1.5 meters, 2 meters, and 2.5 meters. The test at each distance got an average accuracy of 86.6%. The average execution time required for system to detect masker is 8.82412 milliseconds.

Abstract

In 2010 - 2014 the agricultural sector occupied the first position in terms of non-oil and gas exports in Indonesia, it explained that the Indonesian agricultural sector greatly supports the country's economy. One of the results of the agricultural sector is coffee plants that have been recognized by the global market as evidenced by occupying the fourth position in international coffee exports. The number and quality of Indonesian coffee caused Indonesia's coffee exports to rank fourth after Brazil, Vietnam and Thailand. Because 90% of coffee farmers in Indonesia who play a role are small-scale farmers who have agricultural areas between 1-2 hectares and coffee requires temperatures between 20 ℃ - 28 ℃ and humidity between 50% - 70% so that the flavor and quality of coffee produced is satisfying. That is why Indonesian coffee production is not optimal because it lags behind in terms of good coffee processing and technology from other countries. Therefore, to help small-scale coffee farmers in terms of increasing the quality of coffee production, a temperature and humidity control system for coffee bean storage is made using Arduino UNO and the MQTT protocol. The purpose of this system is to detect changes in the temperature and humidity of the coffee bean storage warehouse if the condition exceeds the system parameter point by automatically stabilizing it so that it does not damage the quality of the coffee.

Abstract

The increase in the number of E-commerce retail users is currently growing very rapidly coupled with the effects of the covid-19 outbreak which has made the number of users increase. Therefore, an automation system is needed to help support the improvement of the E-commerce business that can perform tasks efficiently without the need to increase production costs. This system will use the camera to identify objects with images but this image will have noise that affects the identification process. The results of taking pictures of the object will be processed by the Raspberry Pi4 with an Unsharp filter to eliminate noise, then the process of identifying information data from the QR code on the object and determining the initial coordinates of the object will be carried out. The results of this data will later be forwarded to OpenCM to move the manipulator robot using the Inverse Kinematics function. In addition, this system will also send information data to the database for data storage. The use of the Unsharp Filter and QR Code methods in this system produces an accuracy value of 100% with a computation time of 801 ms in 40 times of object reading testing. As for the inverse method, this system has an error of 9.12% to reach the coordinates in 10 times of testing. And to move an object the system requires a computation time of 11 seconds for each type of object for scanning, moving, and storing information from the object.
