Cantilever Jaw Measuring Instruments As Microcontroller Learning Trainers

Abstract

The chewing process has a significant impact on the quality of human life. The condition of the teeth and jaw will affect self-confidence and nutritional intake. This research aims to develop and test a bite force measuring instrument using stainless steel material from car leaf springs for toughness and flexibility - in the form of cantilevers. The research was carried out by making a gnathodynamometer to measure the accuracy and accuracy of the readings. Testing is carried out by p[1]roviding a tool with a known mass and comparing the results with the weight of the mass as well as trialling the use of the tool to Electrical Engineering Education Students which is an educational implementation of Basic Electronics, Electronic Instrumentation, Microcontrollers, and other courses. So this tool is also designed to support students' psychomotor processes by acting as a trainer/learning medium. Development research method with waterfall and respondents 73 students. The device uses Arduino Nano to process bite-force data from the HX711 module. The test used a mass of 45,590; 96.648; and 144,952 Newtons. The results stated that the gnathodynamometer was effective enough to be used with an uncertainty of 0.192 and an RMSE value of 0.554. The study did not measure the maximum capacity of the device due to limitations of the test equipment, and more research is needed before testing on human subjects. The Psychomotor Learning Outcomes graph obtained the percentage of students who completed 83.87%, and the percentage of students who did not complete it was 16.13%. So, it can be concluded that this tool can be used as a learning medium in the form of a bite measuring trainer (gnathodynamometer) which can help students understand the process of using the tool until empirical measurements are recorded and become learning in the use of gnathodynamometer.
