In the COVID-19 pandemic, some of the important vital signs that must be monitored are BPM (Beats Per Minute) and SpO2 (oxygen saturation) as indicators of whether a person is in good health or lacks oxygen to predict the early symptoms of COVID-19. The purpose of this study is to create a device on the patient's wrist that can monitor BPM and SpO2 in real-time, as well as provide notifications on smartphones and emails when the patient's condition is abnormal. The contribution of this study is to implement an IoT (Internet of Things) system using a Wi-Fi connection so that monitoring activities are not separated by distance and time. The MAX86141 sensor is used in the design of this tool to detect the BPM and SpO2 values, after which the data is processed and displayed on the ESP32 TTGO T-Display. Monitoring results are also sent to the Blynk, and if the patient's condition is abnormal, an email notification is sent. According to the tool testing results, BPM has the smallest error of 0.94 percent and the largest error of 6.48 percent, whereas SpO2 has the smallest error of 0.20 percent and the largest error of 3.23 percent. The findings of this study can be used to improve the ease and efficiency of body health monitoring activities. This has the potential to significantly improve public health service quality, particularly during the COVID-19 pandemic</p> I Dewa Gede Hari Wisana Wisana Priyambada Cahya Nugraha Farid Amrinsani Fani Ferina Sani Yusita Indhira Anwar Satheeshkumar Palanisamy ##submission.copyrightStatement## http://creativecommons.org/licenses/by-sa/4.0 2022-09-21 2022-09-21 15 3 10.35882/teknokes.v15i3.317 Sphygmomanometer Sphygmomanometer with Led Bar Display to Improve the Blood Pressure Reading Accuracy http://teknokes.poltekkesdepkes-sby.ac.id/index.php/Teknokes/article/view/321 <p>Instruments in the hospital environment have a role to help and promote more accurate diagnosis and treatment. The general condition of the equipment used and their delivery are very important for a good prognostic. One of them is a device to measure blood pressure called a sphygmomanometer. There are 3 types of sphygmomanometer, namely digital, mercury, and aneroid. Currently, digital sphygmomanometers are known to be easy to use, but their accuracy is low and reduces the ability of nurses to identify blood pressure in humans. Mercury sphygmomanometer has high accuracy, but should not be used because it still uses mercury as a display. This is supported by the Ministry of Health's program to free the world of health from mercury because of the impact of mercury on health and the importance of nurses to train the skills of nurses. The purpose of this study was to reduce the use of mercury which is harmful to humans, in addition to training the nurse's ability to take blood pressure readings on patients. The method used by the researcher is to test the suitability value of the module with the calibrator and to collect data on six respondents to compare the module with the sphygmomanometer that has been traded. The result of the research is the error value when testing the module's suitability value with the DPM (Digital Pressure Monitor) calibrator with a range from 0 to 0.67%. each set point has a different error value. and the lowest error value is among the six set points, namely 0% and the highest error value is 0.67%. Meanwhile, the lowest error value in systole is 0.2% and the highest error value is 2.16%. While the lowest error value in diastole is 0% and the highest error value is 5.55%. Based on the results of the research that has been carried out, the authors conclude that this module is made to replace mercury which is prohibited from being used because it is dangerous for humans and trains nurses' abilities in determining blood pressure readings.</p> Bambang Guruh Irianto Guruh Irianto Sumber Sumber Elmira Rofida Al Haq Mansour Asghari ##submission.copyrightStatement## http://creativecommons.org/licenses/by-sa/4.0 2022-09-21 2022-09-21 15 3 10.35882/teknokes.v15i3.321 Pulse Oximeter Design for SpO2 and BPM Recording on External Memory to Support the Covid-19 Diagnosis http://teknokes.poltekkesdepkes-sby.ac.id/index.php/Teknokes/article/view/303 <p>COVID-19 (coronavirus disease) is an acute respiratory illness induced by exposure to coronavirus 2 in 2019 (SARS-CoV-2). WHO confirms that there were 1.8 million registered deaths in 2020 and that there were 3.5 million recorded deaths in 2021. People who are infected with SARS-CoV-2 without symptoms should have a pulse oximeter. Early detection of low oxygen levels in the blood can lead to fewer complications. Continuously decreasing oxygen saturation, if not controlled, will cause hypoxia (an abnormal respiratory circulation system condition that causes breathlessness). In normal conditions, oxygen levels and heart rate are related. When a person has a shortage of oxygen (breathlessness), their heart rate increases to supply the oxygen. Regulating heart rate can aid in the prevention of disorders such as arrhythmia, coronary heart disease, and hypertension. A pulse oximeter is used to measure the oxygen saturation in the blood and the patient's heart rate (BPM) with non-invasive&nbsp;methods. Conventional pulse oximeters do not support users by not having features such as medical records, which are required for further examination by a doctor. The purpose of this research is to make a pulse oximeter with external storage capability. The difference in wavelength between the red and infrared LED lights that will be captured by the photodiode is measured. SpO<sub>2</sub> and HR values&nbsp;will be generated as a result of comparative measurements. Using a MAX30102 sensor to detect SpO<sub>2</sub> and heart rate, and an Arduino Mega256 to process data for display on the TFT Nextion with&nbsp;Memory Card storage. By comparing the module to a conventional pulse oximeter, data was collected 10 times for each respondent. The maximum SpO<sub>2 </sub>error value is 0.43%, whereas the BPM parameter has the largest error value of 2.02% and the smallest error value of 0.01%&nbsp;based on the data collected. A significant error value is caused by finger movement. The module&nbsp;is usable,&nbsp;based on the results, because the maximum error tolerance for a pulse oximeter is 1% SpO<sub>2 </sub>and 5% BPM, according to the 2001 Ministry of Health Ministry's Guidelines for Testing and Calibrating Medical Devices.</p> Syaifudin Syaifudin Triwiyanto Triwiyanto Dinar Awalin Harditamara Faraz Masood ##submission.copyrightStatement## http://creativecommons.org/licenses/by-sa/4.0 2022-09-21 2022-09-21 15 3 10.35882/teknokes.v15i3.303 Nine Channel Data Logger to Measure Temperature Distribution on Dry Stelizer based on Andoid system http://teknokes.poltekkesdepkes-sby.ac.id/index.php/Teknokes/article/view/306 <p>A temperature measurement in sterilization is needed to find out whether the temperature setting has been reached, because if the tool is operated continuously it will have an impact on the performance of the tool. Data logger is a tool used to record time and temperature by recording. The purpose of this research is to develop technological advances with remote or automated systems that can monitor changes in temperature rise and fall. This study uses 9 types of K-type thermocouple sensors as temperature gauges which are placed at 9 specified points. A thermocouple is connected to the MAX6675 module for conversion which initially detects temperature into digital form data. Data processing uses the Arduino Mega 2560 system and the Arduino programming software processor. HC-05 is used as a data transmission of measured results that have been read where the results are displayed on Android using the Blynk application, the data sent will be in the form of Excel. This tool uses a temperature comparison from the MEMMERT UN 55 incubator in the microbiology laboratory. The error value contained in the 100°C temperature adjustment is 2.6% at a temperature of 1, the smallest error at temperatures 7 and 8 is 0.2% due&nbsp; to the location of the sensor far from the heater. The error value at a temperature of 150°C is 1.7%, the smallest error at temperature 5 is 0.3%, 0.5%. The error value at a temperature of 200°C is 1.8%, the smallest error at temperature 0.5%. This research is expected to make it easier for users to simultaneously monitor temperature and simplify data processing to obtain an accuracy error value in the unit under test (UUT).</p> Anita Miftahul Maghfiroh Singgih Yudha Setiawan Bayu Trisono Aji Pambudi Steyve Nyatte ##submission.copyrightStatement## http://creativecommons.org/licenses/by-sa/4.0 2022-09-21 2022-09-21 15 3 10.35882/teknokes.v15i3.306 Luxmeter Equipped with Proximity Sensor for Operating Lamp Light Calibration in Hospital http://teknokes.poltekkesdepkes-sby.ac.id/index.php/Teknokes/article/view/248 <p>The measurement of the operating lamp light on the operating table is very necessary so that the light rays do not glare during surgery and pathological conditions can be recognized easily without any shadows. This study aims to design a tool to measure light intensity equipped with automatic distance measurement. The design of this tool uses an ultrasonic sensor HC-SR04 to measure the distance between the light source and the sensor module and the MAX44009 sensor to measure the light intensity of the operating lamp displayed on the TFT screen. The design of the tool has been tested on operating lamps. In this study, measurements were made on two light sources, namely the GEA brand operating lamp in the Operating Room RSIA Putri Surabaya and lamps in an Electromedical Engineering Workshop on the Surabaya campus. The results of measurements when using a lamp in an electromedical engineering workshop in Surabaya with the distance between the module and the light source using a 75 cm roll meter, it is known that the error value is 0.0127% for a distance of 100 cm as much as 0.0045%. The module error value when measuring the intensity of light between the tool and the lamp in the electromedical engineering workshop with a roll meter distance setting of 75 cm gets an error value of 0.082% lux and at a roll meter distance of 100 cm, the lux error value is 0.055%. The design of a lux meter that is equipped with a proximity sensor can measure the intensity of light and the distance between the device and the light source and can assist in the learning process with a more effective Luxmeter design that will help Electromedical Technician in testing operating lamps in hospitals become more efficient</p> Levana Forra Wakidi Triwiyanto Triwiyanto Lusiana Lusiana Lamidi Lamidi Artdieansyah Nur Wiaam Isaac John Ibanga ##submission.copyrightStatement## http://creativecommons.org/licenses/by-sa/4.0 2022-09-24 2022-09-24 15 3 10.35882/teknokes.v15i3.248 The Effectiveness Of Moringa Leaf Extract (Moringa oleifera) on Cadmium and LDL Cholesterol Levels in Blood as Indicators of Atherosclerosis in Cadmium (Cd) Induced White Rats (Rattus norvegicus) http://teknokes.poltekkesdepkes-sby.ac.id/index.php/Teknokes/article/view/268 <p>Moringa leaves (<em>Moringa oleifera)&nbsp;</em>have chelating agent properties that act as natural antioxidants in binding heavy metals and free radical scavengers, with cadmium being one of the heavy metals free radicals having toxic effects on the body. Exposure to cadmium can reduce the activity of lipoprotein lipase enzymes (LPL) which function in the triglycerides and free fatty acids catabolism process, and can increase cholesterol and triglyceride levels in the blood. This study aims to determine the effectiveness of Moringa (<em>Moringa oleifera)&nbsp;</em>on<em>&nbsp;</em>Cadmium chloride-induced white rats (<em>Rattus norvegicus)&nbsp;</em>using an experimental research design with a quantitative analysis technique. This study uses the level of cadmium and LDL cholesterol for the dependent variable and the dose of Moringa leaf extract (<em>Moringa oleifera</em>) for its independent variable. The samples used are white rats (<em>Rattus norvegicus</em>) aged 8-12 weeks with a weight of 150-200 grams, along with blood drawn from the heart for the specimen<em>.&nbsp;</em>The researcher conducted the study at the Faculty of Veterinary Medicine, Airlangga University; Surabaya Health Laboratory Center; and Surabaya Bakti Analysis Laboratory from October 2021 to June 2022 using Atomic Absorption Spectrophotometry (AAS) and Chemical Analyzer BS-200. The results show that the average value of cadmium and LDL cholesterol levels in white rats in treatment group 1 are 0.605 g/dL and 8.25 mg/dL, group 2 are 0.075 g/dL &amp; 18.5 mg/dL; and group 3 are 0.08125 g/dL and 12 mg/dL. Based on the statistical analysis of the One-Way ANOVA test, the sig.<em>&nbsp;p-value&nbsp;</em>is &gt; 0.05. Thus, the average value of cadmium and LDL cholesterol has no significant difference. Compared to the 400 mg/kgBW and 500 mg/kgBW, the 600 mg/kgBW dose has the best effectiveness in reducing LDL cholesterol in white rats&nbsp;<em>(Rattus norvegicus)</em>&nbsp;after being induced with cadmium chloride. This study recommends consuming fresh Moringa leaves (<em>Moringa oleifera)</em> as much as 66.522 grams per human/day as an additional antioxidant and chelating agent.</p> Vernanda Arsya Nabilla Indah Lestari Christ Kartika Rahayuningsih Juliana Christyaningsih ##submission.copyrightStatement## http://creativecommons.org/licenses/by-sa/4.0 2022-09-15 2022-09-15 15 3 10.35882/teknokes.v15i3.268 THE THE EFFECTIVENESS OF Moringa oleifera LEAF EXTRACT ON HEPATOTOXIC CASE REVIEWING FROM CADMIUM, SGOT AND SGPT BLOOD LEVELS IN WHITE RATS (Rattus norvegicus) INDUCED WITH CADMIUM (Cd) http://teknokes.poltekkesdepkes-sby.ac.id/index.php/Teknokes/article/view/278 <h1>Moringa leaf (<em>Moringa oleifera </em>Lamk.) is part of herbal plants that have been known for their good natural chelating agent and hepatoprotective properties, especially in hepatotoxic events due to cadmium (Cd) exposure, where flavonoid compounds are contained in the form of quercetin and kaempferol, vitamin A, vitamin C and several phenol components that can inhibit the accumulation of cadmium metals and neutralize free radicals by lowering SGOT and SGPT levels,&nbsp; so this study aimed to determine the effectiveness of moringa leaf extract (<em>Moringa oleifera </em>Lamk.) against hepatotoxic in white rats (<em>Rattus norvegicus</em>) induced with cadmium. This study was expected to provide potential of Moringa leaves in hepatotoxic case at dose 400 mg/kgwb, 500 mg/kgwb and 600 mg/kgwb in white rats. This research was an experimental study with quantitative analysis conducted at the Faculty of Veterinary Medicine, Airlangga University, Surabaya Health Laboratory Center, and Bakti Analisa Laboratory in November 2021 – July 2022. The independent variable was the dose of Moringa leaf extract and the dependent variables were levels of cadmium, SGOT and SGPT in white rat blood. Analysis of blood cadmium levels using an atomic absorption spectrophotometer and analysis of SGOT SGPT levels using the BS-200 Chemistry Analyzer. The results showed that the average blood cadmium, SGOT and SGPT levels in treatment group 1 were 0.0605 μg/dL, 260.175 U/L, and 143.85 U/L; in treatment group 2 were 0.075 μg/dL, 250.925 U/L and 77.575 U/L; in treatment group 3 were 0.08125 μg/dL, 171.475 U/L and 66.075 U/L. Based on statistical analysis of One-way Anova test, sig. p value &gt; 0.05, there was no significant difference in cadmium and SGOT levels. Then, the results of the Kruskal wallis test on SGPT levels showed sig. p value &gt; 0.05, there was no significant difference in all treatments. Moringa leaf extract at a dose of 600 mg/kgbw/day had the best effect as chelating agent and hepatoprotective compared to doses of 400 mg/kgbw/day and 500 mg/kgbw/day at cadmium induction for 10 days. From this study, we recommend to consume about 66,522 g/day Moringa fresh leaves as the natural chelating agent and hepatoprotector for overcoming acute hepatotoxic case.</h1> <h1>&nbsp;</h1> <h1>INDEX TERMS Moringa Leaves, Cadmium, SGOT, SGPT, Rattus norvegicus, Atomic Absorption Spectrophotometer, Chemistry Analyzer</h1> Devi Puspitasari Indah Lestari Christ Kartika Rahayuningsih Juliana Christyaningsih ##submission.copyrightStatement## http://creativecommons.org/licenses/by-sa/4.0 2022-09-16 2022-09-16 15 3
