Abstract

Ultra High Temperature cow's milk is a type of milk that is widely consumed by humans from children to adults because milk has a myriad of health benefits, but if the cleanliness of the processing is not maintained, milk quickly becomes unfit for consumption and can cause various adverse effects for a person who consume it. There are many ways to determine the appropriateness of consuming milk, such as by looking at its color, smelling the aroma, or tasting the milk, but these methods are ineffective and raise doubts about whether milk is still suitable or not suitable for consumption. This study designed a system to determine the feasibility of Ultra High Temperature cow's milk based on pH parameters, ammonia gas content, and color. To determine the value of each parameter, a PH 4502C sensor, MQ135 gas sensor, and TCS3200 color sensor are used to carry out the process of determining the feasibility of milk using the Naive Bayes classification method which is processed with the Arduino Mega 2560 microcontroller. The results of the accuracy of the system test to determine the feasibility of milk Ultra High Temperature cattle based on pH parameters, ammonia gas content, and color with the Naive Bayes classification method using 40 training data and 20 test data is 85% with a computation time of 1,911 seconds.

Abstract

The development of highly advanced technology allows for the transmission of data without media or what is commonly called wireless (wireless) including sending power commonly called Wireless Power Transfer (WPT). Many factors are known in power delivery at WPT, one of which is the coupling coefficient (k) value. So far, the k-value approach has been carried out by entering values between 0 and 1, making this WPT research inefficient. Therefore, the solution that researchers can provide is to design a coupling coefficient detection algorithm based on frequency response with the Manhattan distance metric. This algorithm will detect the coupling coefficient value based on the frequency and power values at the input. The output result of this algorithm is the corresponding coupling coefficient value. The dataset used in this study consisted of 19 classes with each class totaling 1000 data so that the total dataset was 19000 data. The test results of this study are based on test data, namely getting an accuracy of 95% for coupling coefficient detection, the average computational time required for testing is 0.0274 seconds, and the percentage of error rate from the comparison of the algorithm with the simulation results is 0%..

Abstract

Today, governments or any office attendance system still uses paper or RFID (Radio Frequency Identification) and finger prints in their office, and if someone needs to work outside the office, it will be difficult to maintain and monitor their employee. Therefore, the writer suggests an attendance system with their selfie picture based on their location. Because everyone nowadays uses their smartphone for communication, implementing this attendance system is the best solution, as the employee begins by logging in with their credentials, uploading a selfie photo with geotagging, and displaying their time and location. The server that maintains their data must be checked, and testing the network performance from outside the office using either a cellular network or fixed broadband from the employee side started with filling out their credentials to upload their picture, which contains geolocation, and showing up their time and location for monitoring.

Abstract

Hypothermia is a condition where the body temperature is below average and the body does not have the ability to produce heat properly due to a weakened heart rate and common in climbers who climb mountain. Hypothermia can be dangerous if not treated immediately because people with hypothermia usually don't know that they have hypothermia. In this study, a tool was designed to detect hypothermia with classfication method using the Fuzzy Logic Tsukamoto Method. Fuzzy input come from the MAX30102 sensor to calculate the number of heartbeats, and the DS18B20 sensor to calculate body temperature. Because the tool will be used in climbing areas that have limited power sources, the tool requires a mechanism to save its power. In this study, the low power mode mechanism is used which is applied to the ATmega328P. When the tool is not in use, the system goes into sleep mode and will return to wake mode if the trigger made of a push button is pressed. This system has 2 components that function as output, the 128x32 OLED used to display sensor readings and classification results and a buzzer that will emit a sound if the user is detected to have hypothermia. This study obtained an accuracy of 96.45% on the MAX30102 sensor in the heart rate reading test. In testing the temperature readings, this study obtained an accuracy of 99.41%. In testing the accuracy of the Fuzzy Tsukamoto Method, a value of 100% was obtained with an average computation time of 395.6 µs. As well as the low power mode mechanism which has managed to reduce the average current usage by up to 72.2%.

Abstract

Wireless energy transfer technology has enormous potential, in the field of transportation, for example, to charge a running vehicle. Many variables can affect the efficiency of energy transfer that occurs, one of the discussions in previous research by Akbar, S., et. al. (2021) regarding wireless power transfer, namely the effect of entering the frequency value on the value of the power transferred through a particular wireless power transfer circuit. In this study a frequency generator is made to output a signal that can be used in a wireless power transfer circuit. This research discusses the engineering of the generator frequency using a microcontroller, to produce a PWM signal with a certain frequency, and an IRF3205 Dual Motor MOSFET H-bridge to convert it into an AC signal. The engineered system also uses button and screen interaction with the user as well as monitoring the power drawn by the WPT circuit with the sensor. Based on testing, the system has succeeded in delivering energy and the effects can also be seen at different frequencies. For the output of the system itself, there is an average frequency error value of 0.27% and a maximum error value of 1.01% at a frequency of 121kHz.

Abstract

Plagiarism is an act that harms other people and educational institutions. Currently there is software that can prevent acts of plagiarism, especially in the academic field, namely turnitin software. Turnitin also adopts Artificial Intelligence technology where the system will check the text in uploaded files to find out if this file is affected by plagiarism or not. The use of turnitin software as a plagiarism detection tool raises various perceptions. Through the use of turnitin software, students who commit acts of plagiarism can be detected, so that the writing they write will be obtained and it will be known how much the percentage level of plagiarism is in the writing. While the lecturer's view is that the rules for writing papers that are declared plagiarism must have standards. This is done in order to reduce the level of plagiarism. Thus, this study aims to determine the differences between lecturers and students in viewing turnitin to avoid/detect plagiarism as well as things that are perceived as detrimental/beneficial in using turnitin. At the data collection stage it will be carried out in the lecturer room for lecturer sources and for student sources it will be done online. The interview method used is semi-structured interviews. The data obtained was analyzed using thematic analysis. The findings of this study resulted in two themes, namely the use of turnitin software by lecturers and student behavior regarding the use of turnitin software with 9 categories and 16 codes.
