Abstract

The ear is an organ that is able to detect or recognize sound and also has a lot to play in the balance and position of the body. The ears are organs that are very vulnerable to noise. There are two common causes of hearing loss, namely decreased hearing conduction (hearing loss) and nerve hearing (sensorineural hearing loss). To prevent deafness, hearing control is necessary. Generally to test hearing function is done regularly by the ENT doctor at the hospital. This if done many times is deemed ineffective because it is time consuming and requires relatively expensive costs, therefore an early diagnosis of portable hearing loss is designed that is expected to be able to test independently independently over and over again. This tool is equipped with SD Card data storage, where the results of the data can be consulted by a doctor for further diagnosis. This tool uses an arduino uno R3 control, the frequency generator uses IC XR2206. The highest error is at the frequency of 8000 Hz which is 0.52%, but overall all systems on the device are functioning properly and the error is still within tolerance of 10%. From the results of these data, this tool can be recommended for early diagnosis of hearing function.

Abstract

Vitiligo is a skin disorder caused by a lack of melanin pigment in the skin, which causes white patches on certain parts of the skin because this melanin pigment is not able to produce the skin color. Previously, one of the treatments for vitiligo was using a UVB lamp with a 311 nm wavelength that could not yet be adjusted to dim the lights as safety when conducting therapy. Therefore, the research aims to design a simulation of the vitiligo therapy device equipped with a timer LED lamp, a safety of lighting, and the data storage. The data are stored in the SD Card to make it easier for patients to control changes before and after therapy. The simulation of this therapeutic apparatus is controlled using the Arduino Uno system and regulates lightning protection using a PWM circuit and ultrasonic sensors. The highest error obtained is 2.4%. at 5 cm. The overall device system, namely timer, buzzer, hour meter, and data storage has been working well and the error value is still within tolerance which is below 5%. Thus, it is hoped that this vitiligo therapy simulation device is able to operate as a real therapeutic device

Abstract

The purpose of the research was to make an Arduino-based mini shaker for automatic mixing of chemical solutions. The use of the tool was expected to save time and energy in the process of mixing chemical solutions, facilitate laboratory workers in mixing the chemical solutions quickly and efficiently, and for a safety reason in the laboratory. The design of this tool consists of a time sensor, speed sensor, microcontroller, motor driver and Dc motor. This tool can regulate the speed of a DC motor with three speeds namely 100 RPM low, 150 normal RPM, and 180 high RPM. Based on the results of motor speed measurements, the average error at the motor speed is low 1.4%, normal 2.5%, and high 2.54%, and the average error at the timer is 1 minute 0.03%, 2 minutes 0,1%, 3 minutes 0.05%, 4 minutes 0.016%, and 5 minutes 0.03%.

Abstract

This research will discuss health services in the role of diagnostics and life support. The system designed is a system that is able to provide information on the user's health condition, in this case, is a measure of heart rate and body temperature. In taking heart rate data using a heart rate sensor (fingertip sensor). This system works taking data from the blood flow on the index finger for the 60s, the data will be displayed through the LCD. For body temperature parameters the data collection uses the LM35 temperature sensor. Changes in sensor heat will be converted into electricity, which is translated into digital form through a 10-bit ADC that is processed by the ATMega 16 microcontroller and displayed to the LCD. The results of an ideal measurement show the error of each parameter heart rate and body temperature min 1.702% and 0.55%
