Abstract

In the medical field, the ideal body weight is an index of the body in good health in terms of health. therefore, to find out a person's weight is ideal or not, the Body Mass Index (BMI) formula was created. Body Mass Index (BMI) is a simple tool or method to monitor ideal body weight status. The author conducted research on the design for measuring height and weight with Body Mass Index (BMI) information which is expected to make it easier for users to find out the ideal weight without having to calculate it manually. The purpose of this study is to determine the percentage error of weight comparison between the load cell sensor and conventional scales, to determine the percentage error in the comparison of the height of the VL53L0X sensor to a conventional meter, and to determine the accuracy and error value of BMI on the measuring instrument for Height and Weight With BMI Information (Body Mass Index) Using Sensor VL53L0X and load cell. The method used by the author to obtain the research objectives is a data collection method that is supported by a study of literature. Broadly speaking, the steps in this research method include designing electrical, mechanical, and application systems. In this study, testing was conducted on 10 people. Each person was measured using a load cell sensor and VL53L0X to obtain their weight and height data, which were then processed and compared with conventional measurements. The results of the study show that the percentage error of weight comparison between load cell sensors and conventional scales is between 0% - 0.615%. The percentage of error in comparison of the height of the VL53L0X sensor with conventional meters is between 0% – 1.974%. The average value of accuracy or accuracy of the tool BMI is 99.050% while the average for the tool BMI error value is 0.95%. The level of accuracy in BMI units in the comparison between the theoretical BMI value and the tool BMI is in the range of 0 – 0.68
