Abstract

Currently, thermometer has been widely used by the public. In general, thermometers are designed for people who have normal physical conditions, especially in the ability to see. Disabled people, especially blind people, will find it difficult to use the existing thermometer, especially with the current pandemic situation, which is likely to spread COVID-19 quickly. In connection with this problem, non-contact body temperature measurement is needed with sound output and a wireless system so that there is less possibility of exposure to disease. Therefore, this study describes a non-body contact thermometer with sound output via wireless. The purpose of this study concludes that Non-Body Contact Thermometers can be made with Voice Output Via Wireless to determine normal or hyper and hypo human body temperatures. Thus, this thermometer make it easier for those who have limitations to see and reduce exposure to covid-19 between patients and users. The method in this study employed MLX90614 as a sensor whose output is in the form of digital data, HC-SR04 as a trigger on the MLX90614 sensor, and DF player as a reader on data that have been recorded via Google and stored on the SD card, and XBEE module as transceivers of data to pc. Temperature testing was further conducted by comparing the module with a standard tool, that is a digital thermometer. The error obtained from the module at normal temperature is 0.98%, while the smallest error is 0.1%. Furthermore, in terms of the hypo temperature, the largest error is 1.80%, while the smallest error is 0.42%. Last, at hyper temperature, the largest error is 1.75%, while the smallest error is 0.10%.

Abstract

The intensity and quality of the X-Rays a patient receives is determined by the exposure factor. Voltage (kV), Current (mA), Time (seconds), and tube-to-film distance (FFD) are exposure factors that can be controlled and determined. The key factor that can determine the quality of X-Rays is the tube voltage (kV) which affects the X-Rays to penetrate objects. The purpose of this research is to improve image quality and relatively affordable manufacturing costs by obtaining the difference in the detector catch value between dark and light by utilizing the response of the PH101 phototransistor sensor. The contribution of this research is that the system can display grayscale and numeric on a 16x16 pixel matrix using the Matrix Laboratory (MATLAB) application. This research can convert images taken from analog data after measuring the phototransistor PH101 on X-Rays. The measurement settings used are 50, 55, 60, and 70kV, with a tube current of 40 mA and an irradiation time of 1 second. The measurement results show that the Flat Panel Detector Design can respond to differences in doses and objects. This research shows that a Flat Panel Detector and a Phototransistor PH101 sensor have been successfully made which can be used to capture X-Rays so that the black level of the film can be determined.

Abstract

High Flow Nasal Canulla (HFNC) is a technique that provides a high flow of heated and humidified gas. HFNC is simpler to use and implement than noninvasive ventilation (NIV) and appears to be a good alternative treatment for hypoxemic acute respiratory failure (ARF). This study aims to help facilitate medical personnel or equipment operators in monitoring the flow that enters the patient's body so that oxygen therapy can be given according to the right dose. This study uses an Arduino microcontroller to process the output flow from the Sensirion SFM-3000 flow sensor, then the processed flow value will be displayed on the TFT LCD. The independent variable in this study is the flow setting value, while the dependent variable is the SFM-3000 flow sensor. The largest error flow value is in the setting at 30 LPM with an error value of 2.70%. The flow value is set using a flowmeter, while the comparison tool used is a flow analyzer (Citrex H3). In the testing phase, the measurement value is 10 LPM to 60 LPM with a time of 5 minutes at each point. Based on the measurements that have been made, the largest error value is obtained at the value of 30 LPM, which is 2.70% and the smallest error value is at the value of 60 LPM, which is 0.74%. Data retrieval using a compressor and central oxygen is very influential on the results of the flow and oxygen concentration. The results obtained are more stable than without the use of a compressor and central oxygen.The conclusion from these results is that the calibrator module has a relative error (error value) that is still within the allowable tolerance limit, which is ±5%. And also the design of this tool is portable and low cost and is made to be used in hospital agencies as a support for maintenance on HFNC equipment
