Abstract

Stroke is a sudden brain disorder caused by vascular disorders and can cause death that lasts for 24 hours or more. According to the WHO report in 1999, stroke was ranked second in the world in the highest mortality rate. In Indonesia, according to Riskesdas data from the Indonesian Ministry of Health, there was an increase in the probability of having a stroke by 8.3 per mile in 2007 to 12.1 per mile in 2013. This is evidence that there has been an increase in the number of stroke patients in Indonesia from the year 2013. from year to year, the Government has not found a solution to prevent stroke. Stroke is a disease that must be treated quickly because it can cause disability or death. Therefore, the problem of stroke requires a system that makes it easier for a health expert to detect stroke risk so that it can reduce the number of stroke risk patients. In this system, the ELECTRE method and weighted product are used to detect early risk of stroke because both methods can eliminate patients who are not in accordance with the characteristics and can choose the best alternative and classify stroke patients into high, medium and low categories. Based on the test results comparing the results of detection by the system with the results of manual detection with 30 test data, the accuracy value is 86%.

Abstract

Soil is one of the planting media. The soil has several main factors for plant growth, including moisture and soil acidity.The level of soil moisture and soil acidity can determine the fertility of the soil and also suitable crops for planting on the soil.Some of the existing tools can mostly only determine the level of soil moisture or acidity, without telling the level of soil fertility and also the plants that are suitable for planting on the soil.From these problems, I conducted research to create a system that can detect the level of soil fertility and suitable plants on the soil based on the level of humidity and acidity of the soil.This system uses two kinds of sensors, namely a soil moisture sensor and also a soil pH sensor.These two sensors are connected to an Arduino Nano microcontroller that is operated using an Android application.The results of this study are in the form of a tool that can detect the level of soil fertility and also the type of plants that are suitable on the soil based on the level of humidity and acidity and an Android application that is connected to the tool using Bluetooth as a medium interface on this system.The grouping of soil and plants is carried out using the k-Nearest Neighbors (k-NN) method.In this study, the selection of the classification method used k-NN because the data used was secondary data and the purpose of this method was to classify objects based on attributes and test data so that it was suitable for my research that have 90% accuration..

Abstract

Monitoring the number of visitors in public places that apply PPKM rules is difficult to do manually if in a short time too many visitors come and go. Checking symptoms of suspected COVID-19 cases in public places using only visitors' body temperature parameters is still less accurate considering the symptoms of suspected COVID-19 have several parameters that can be measured. This study developed a system that can calculate visitor capacity automatically and can measure symptoms of suspected COVID-19 in three parameters, namely body temperature, oxygen saturation in the blood, and respiration time. The measurement results of the three parameters will be classified into two classes using the Random Forest method. The system output is displayed by LCD containing text of the sensor measurement value and the classification results as well as the sound produced by buzzer containing an appeal to implement health protocols. The results of oxygen saturation measurement test using the MAX 30100 sensor obtained an average accuracy of 98.98%. Measurement test of body temperature using the MLX 90614 sensor obtained an average accuracy of 99.29%. Measurement test of respiration time using the KY-037 sensor obtained an average accuracy of 97.65%. Measurement test of visitor capacity using the PIR sensor obtains an accuracy of 100%. The test results of fifteen test data against the Random Forest classification achieved an accuracy of 100% with an average computation time of 35.3 s.
