Abstract

Heart disease or cardiovascular disease is one of leading causes of death worldwide. In Indonesia there are more than two million cases per year. Premature Atrial Contraction (PAC) is a heart disease in the atrium section where this heart rhythm disturbance occurs with symptoms of a faster or slower and irregular heartbeat. Currently, Premature Atrial Contraction (PAC) examination is performed by cardiologists with patients undergoing ECG tests. However, the cost of ECG examination is quite expensive and also the pandemic conditions caused restrictions to public places and hospitals. Therefore, a solution is offered in this study to identify early PAC heart rhythm disorders. This study makes a prototype using several devices such as Arduino Nano as Microcontroller, AD8232 Sensor and Electrodes to get ECG signal and also LCD to display the heart information output either “normal” or “PAC”. The main features in this system are RR intervals and QRS complex and apply classification using Naive Bayes Classifier. The results of the naive bayes classification in this study achieved an accuracy value of 91,67% using 24 training data and 12 testing data with an average computation time of 3,35 milisecond.

Abstract

Nutrition is a health status based on a balance between needs and nutrients. Toddlers can be said undernourished if the measurement of the W/A z-score <-2SD, and stunting if the measurement of the H/A z-score <-2SD. Currently, the determination of nutritional status and stunting is still using conventional measurements and matched with the standard book table of children's nutritional status from the Ministry of Health. Therefore, a system developed can detect weight and height as well as nutritional status and risk of stunting in toddlers. This system uses ultrasonic sensor HC-SR04 to measure height, load cell and HX711 module to measure weight and backpropagation NN to predict nutritional status in toddlers. The implementation of nutritional status with the backpropagation NN method is divided into 2, namely nutritional status with poor and good classes, and stunting risk with low and high classes. The system has a height of 125 cm and a square footing with a width of 30cm x 30cm. Using MLP Topology Workbench for data panning using 3 input layers, 12 hidden layers, and 1 output layer for each backpropagation NN implementation. The ultrasonic sensor test got an accuracy of 98.5%, the load cell sensor test got an accuracy of 94.7%, the test on the method got 100% accuracy, and the overall system test got an accuracy of 96.6%.

Abstract

Cooking oil is a staple ingredient that people consume in their daily life. There are various types of oil circulating among the public, including packaged oil, bulk oil, and used cooking oil. The use of cooking oil repeatedly can damage the quality of cooking oil and increase the risk of several diseases, including carcinoma. To determine the quality of oil, there are several kinds of chemical tests, including the determination of the peroxide number, saponification number, iodine number, and acid number. And can also be seen directly through the color and clarity of the oil. The design of this classification system uses color and clarity as input features of the system and used cooking oil as test objects and system datasets. To measure color and clarity, TCS3200 and LDR sensors are used. The classification process starts from inserting the used cooking oil object into a 50ml beaker glass, then inserting the beaker glass into the system with a 1cm position next to the TCS3200 and LDR sensors. The light will pass through the object and go to the TCS3200 and LDR sensors, then the reading results will be sent and processed via Arduino UNO using the K-Nearest Neighbor method and the final result in the form of proper and less appropriate classification will be displayed on the LCD monitor. The K-Nearest Neighbor classification was chosen because it is considered to have good accuracy with a limited dataset. The dataset is divided into 2, namely, 17 training data and 8 test data. From the results of the tests carried out with 8 test data for used cooking oil, the accuracy results were 75%.
