Abstract

Big Pandemic Covid-19, In ​​Indonesia Deaths due to the Covid-19 virus up to 144,000 thousand people. One of the causes of the high number of deaths due to Covid-19 cases is the lack of prompt treatment for patients affected by Covid-19 in the cytokine storm phase. Cytokine Storm is a condition in which the release of mal-adaptive cytokines is “out of control” in response to infection and stimuli. Cytokine storms attack lung tissue and blood vessels. In this study, a system consisting of several components was used, namely, Arduino Mega 2560 Rev 3 as a microcontroller board, NTC Thermistor Sensor as a breathing signal generator mounted on an oxygen mask and an OLED display to display the output in the form of "Normal" or "Abnormal". This system uses the Min, Max, Amplitude, Interval and Breath Rate features per 4 cycles of 4 cycles which are then classified using the Support Vector Machine. In system testing related to testing the accuracy of the classification results using the Support Vector Machine, it was carried out 12 times to find the class of the test data obtained and the accuracy level of the classification results with SVM was 91.66. In the computational testing of the system, the classification was carried out 12 times to get the class classification results from the test data and the average computation time was 29.29 ms.

Abstract

Melon fruit has a sweet fruit taste, thick flesh, and disease resistance. A good quality melon has the characteristics of the outer skin not breaking or cracking, the flesh is free from internal bruising and browning, and the fruit is free from diseases that affect the general appearance. For diabetics, choosing a sweet melon will certainly cause problems. To determine the level of sweetness of the melon, it is first split to take a sample of the liquid and tested on a refractometer. This is certainly not practical, so innovation is needed to determine the level of sweetness of melons by processing the image with a digital image processing process. This study uses a digital image processing process by distinguishing the sweetness level of melons into 3 classes, namely low sweetness level, medium sweetness level, and high sweetness level. Method of Gray Level Co-occurrence Matrix used in this study to perform feature extraction using 5 features that correlation, Contrast, homogeneity, dissimilarity, and Energy with variations in the distance d= 1,2,3,4 and angle θ= 0°,90°,180°,270°. In the melon sweetness classification method, Decision Tree is used to distinguish low, medium, and high sweetness classes. This study used 435 data sets with 390 training data and 45 test data resulting in an accuracy of 80% at low sweetness level, 73% at medium sweetness level and 80% at high sweetness level. The best average computing time obtained at the low sweetness level is 3.87 seconds.

Abstract

Every living thing need water to life. One of the uses of water is to fill swimming pools. Swimming pool cleanliness becomes a problem, such as pollution of swimming pool water with urine. Not only that, swimming pool water must also pay attention to the temperature, pH and turbidity of the water so that the quality is maintained. However, the quality monitoring process seems slow and is not carried out regularly and continuously. Sometimes, the monitoring process carried out gets inaccurate results and impratical in practice. Therefore, a swimming pool water quality monitoring system was created with a fuzzy logic algorithm, assisted by the eFLL (embedded Fuzzy Logic Library) library which is used to determine whether the water quality is good or bad by processing the data obtained by the DS18B20 temperature sensor, pH -4502C and also the dfrobot turbidity sensor. Arduino Nano microcontroller is used with Atmega328 as a data processor obtained from the sensor. Then, with serial communication via bluetooth, users can see the monitoring results on an android smart phone. The test is carried out by measuring the quality of the swimming pool water in the morning and evening with an interval of 8 hours to get 40 test data. The results obtained are in the form of monitoring and storing data on smart phones. The accuracy of the DS18B20 temperature sensor is 98.75% with an average error of 1.25%, the pH-4502C sensor gets an accuracy of 97.52% with an average error of 2.48% and also the turbidity sensor test results that when the water is getting cloudy, the voltage value will be smaller . In addition, the accuracy of the fuzzy logic algorithm compared to MATLAB is quite high that is 98.49% with an average error of 1.51%..

Abstract

Health is measuring the human condition itself based on mental and physical conditions. Health conditions can be determined by measuring their vital signs, namely heart rate and body temperature. One of the most important organs for humans that will be fatal if exposed to disease is the lungs. The use of wearable devices to check these important organs will be easy. The use of wearable devices that are used in daily activities will not last long if they use battery power. For this reason, the system utilizes the low power method to save the power used. This sleep mode feature will be implemented in a system that can monitor the state of the human body through temperature, heart rate and blood oxygen levels. In the heart rate reading test, the percentage of error during normal conditions is 9.42% and during exercise is 5.99%. In the temperature reading test, the error percentage is 2.44%. Sleep mode on the system is able to reduce current by 22.29% from 34.36 mA to 26.7 mA.

Abstract

COVID-19 affects consumers' lifestyles, especially in ordering food online. Ordering food online is like using an online food ordering service application. The obstacle faced by this lifestyle is the wastage of food costs. Another obstacle is that there are consumers who do not have time to prepare food independently in order to reduce costs. This can be accomplished with alternatives such as daily meal ordering which prepares scheduled breakfast and lunch at affordable prices. Therefore we need a system that can help bring together daily catering providers and their customers. The system that is built must have high mobility so that it has easy access. In this study, two Android-based applications that are integrated with each other will be built. Determination of functional requirements or application features applying the Minimum Viable Product (MVP) methodology. The development flow follows the Software Development Life Cycle (SDLC) Waterfall. Functional requirements testing using the black box testing method with validation testing techniques. Non-functional testing using the System Usability Scale (SUS) questionnaire method produces an average SUS scale value of 80.5 for usability in customer applications and 66 for usability in vendor applications. With this application, it can help connect daily catering providers with customers in an efficient and integrated manner.
