<![CDATA[A surface's verticality or horizontalness can be determined as well as its flatness using a waterpass or spirit level. The alignment and flatness of the X-ray tube and bucky table, which determine the perpendicularity of the X-ray beam, is one of the factors for the Conformance Test, according to PERKA BAPETEN No. 2 of 2018. A traditional waterpass is typically used to obtain that conclusion, but the measurement outcome is still subject to human error because there is no set value. To aim for exact alignment, A digital waterpass using the MPU6050 sensor is made, which produces precise X-Ray images, reduces noise in the form of shadow magnification, and investigates the function of the waterpass in the compliance of the X-Ray unit. Arduino is used as the data processor in this investigation. The output is then shown on an LCD and transmitted over Bluetooth to a computer where it is displayed using Delphi before being saved in Excel. With the deviation standard value of 10 degrees, we have obtained an error value from this research between 2% and 3%, minimum, which is 0.04 for sensor 1 and 0.25 for sensor 2. Sensors 1 and 2 measure 14 degrees at 0.089 and 0.054, respectively. The MPU6050 sensor can be utilized in this study to determine how flat the X-Ray tube and bucky table are about one another. This study's contribution is anticipated to be more effective tool testing, and the data will be kept on file until the next testing session.]]>

<![CDATA[Digital thermometers are measuring instruments needed to perform temperature measurement actions and must be calibrated periodically according to standard measurement methods. The purpose of developing this tool is to add PID control to the calibration media where PID control aims to regulate the stability of the temperature setting to be achieved. This is achieved by studying and evaluating the effect of temperature stability on the heater and LM35DZ temperature sensor. This research method uses the Arduino Nanosystem for data processing and PID system control. The LM35DZ temperature sensor on the heater is regulated by a 2 Channel SSR module using a PID system then the temperature generated by the heater will be read by the LM35DZ and displayed on the LCD. The results of this study, digital thermometer calibrator measurements have been successfully carried out by comparing 3 digital thermometers with different brands, namely Omron 343F, Omron 245, and ThermoOne. The difference in error values in oil media is 3-4% and in water media 2-4% with the value of time stability in water media for 3-3.3 minutes and in oil media for 1-2 hours. With this comparison of calibration media, it is hoped that it can help in measuring temperature with better and more effective results. find methods, results, conclusions.]]>

<![CDATA[Accurate monitoring of NIBP (Non-Invasive Blood Pressure) parameters using vital sign monitors is crucial for patient care. Therefore, calibration of vital sign monitors is essential to ensure their safety and reliability. A vital sign simulator was developed in this study, integrating ECG and NIBP parameters with a TFT Nextion display. The aim is to calibrate ECG and NIBP readings on vital sign monitors. The system utilized the Arduino Mega 2560 as the central controller and the MPX5050GP sensor for NIBP measurement and motor pump control. The NIBP parameters were measured at two settings: 60/30 and 80/50. The results showed a maximum systolic error of 3.5% and a diastolic error of 5.6% for the NIBP setting of 80/50. The largest standard deviation value of 2.05 was observed at the NIBP setting of 60/30. The highest uncertainty value of 0.5 was also found in the NIBP 60/30 setting. The obtained data indicated stable module readings within the acceptable threshold for vital sign monitor calibration. The developed vital sign simulator offers a reliable means of calibrating NIBP parameters, enabling accurate blood pressure measurements. Further research and refinement can be conducted to enhance the system's precision and expand its capabilities for calibration of additional vital sign parameters. By ensuring accurate calibration, healthcare professionals can rely on vital sign monitors for effective patient monitoring and diagnosis.]]>

<![CDATA[One of the causes of the high maternal mortality rate is dominated by three factors, one of which is preeclampsia. Preeclampsia is a condition in which the mother experiences hypertension and changes in BMI (Body Mass Index) at the 20th week of gestation. Preeclampsia indications in pregnant women are related to examinations, namely Antenatal care (ANC). Antenatal care is one of the prenatal checks with certain standards. Pregnant women need extra antenatal supervision from health workers. Preeclampsia detection carried out in health care facilities is currently considered to be still not optimal so that there are still many cases of preeclampsia that are not handled properly. A web-based ANC test is one of the ways that services for pregnant women may be improved. To make NIBP and BMI data supplied and received by IoT media helpful for the diagnostic procedure, this study will evaluate them. Knowing the reaction of NIBP and BMI data provided and received over IoT medium is the contribution of this research. The MPX5050 sensor and Loadcell, whose output will be processed and presented on a web page, will be used in the technique to accomplish this purpose. Although the largest error value was -5.4 at the measurement point of 150 mmHg at diastole, it can be argued that the measurement findings for the NIBP parameter are plausible. Overall NIBP measures, however can be considered practicable and can be used to human measurements. Additionally, the weight parameter measurement data have an error value of 0.19328%. From this study, it can be inferred that transmitting IoT-based NIBP and BMI data has an impact on received lost data or delays. The findings from this study are expected to be developed in further research.]]>

<![CDATA[Infusion devices are the basis for primary health care, that is to provide medicine, nutrition, and hydration to patients. One of the infusion devices is a syringe pump and an infusion pump. This device is very important to assist the volume and flow that enters the patient's body, especially in situations related to neonatology or cancer treatment. Therefore, a comparison tool is needed to see whether the equipment is used or not. The purpose of this research is to make an infusion device analyzer (IDA) design with a flow rate parameter. The contribution of this research is that the tool can calculate the correct value of the flow rate that comes out of the infusion pump and syringe pump. The water released by the infusion pump or syringe pump will be converted into droplets which are then detected by the sensor. This tool uses an infrared sensor and a photodiode. The results obtained by the sensor will come by Arduino nano and code it to the 16x2 Character Liquid Crystal Display (LCD) and can be stored on an SD Card so that it can be analyzed further. In setting the flow rate for the syringe pump of 100 mL / hour, the error value is 3.9, 50 ml / hour 0.02, 20 mL / hour 0.378, 10 mL / hour 0.048, and 5 mL / hour 0.01. The results show that the average error of the syringe pump performance read by the module is 0.87. The results obtained from this study can be implemented for the calibration of the infusion pump and the syringe pump so that it can be determined whether the device is suitable or not]]>

<![CDATA[The purpose of this study is to design a tool that is used to replace a conventional scalpel with a tool that utilizes high frequency in order to eliminate faradic effects on body tissues where the high frequency will be adjusted to the duty cycle which aims to obtain various types of surgery required by doctor. That makes the Electrosurgery Unit is important to build because it can cause loss of a lot of blood during surgery less than using a conventional scalpel. Electrosurgery Unit can also be used for coagulation which means some surgery doesn’t just need dissection but also seal some tissue to reduce or cut loss of some diseases at the patient. The result of the high frequency which is regulated by the duty cycle, will then be centered at one point on an object. In this study, the researchers took advantage of the type of heat effect produced by high frequencies, which were concentrated at one point so that it could be used to carry out the process of surgery (cutting) and coagulation (coagulation) on body tissues so as to minimize the occurrence of large blood loss. The researcher took advantage of the high frequency of 400 kHz generated by the oscillator circuit and then set it with a duty cycle program on the Arduino of 6% on 94% off for coagulation and 100% on for cutting. The module design consists of a 400 kHz frequency generator, a pulse control circuit to adjust the duty cycle, a power control circuit as a power setting, a driver circuit to combine the frequency with the set power so that different outputs are obtained according to the settings, an inverter circuit to increase the voltage. and an interlock circuit as a bipolar and monopolar output separator]]>
