Abstract

Health problems with cardiovascular system disorders are still ranked high, according to data from the WHO reported that there are about 31% of causes of death globally are cardiovascular diseases. The purpose of this study was to develop a 12 lead electrocardiograph with 2 displays and the HC-05 as a real-time transmitter of heart signal data. The electrocardiogram signal is obtained from the wiretapping by attaching the electrode cable to the Lead I, Lead II, Lead III, aVR, aVL, and aVF leads, then processed on IC AD620, HPF and LPF filters and non-inverting amplifiers and then processed using Arduino UNO for further display. in the form of a signal on the Delphi 7 application. The research method is to measure the heart signal on the ECG Simulator, by testing several BPMs, namely 30, 60, 120 and 240 on each lead. After testing the signal equation at the 0.5mV setting by calculating the error rate, the highest error value is obtained in lead I, lead aVL and aVF of 7.14% and the smallest error is 3.57% error in lead III. Then at the 1mV setting by calculating the error rate, the highest error value in lead aVL is 7.14% and the smallest error is 2.36%. at the 2mV setting by calculating the error rate, the highest error value is obtained in leads aVL and aVF of 5.71% and the smallest error is obtained by an error of 2.1% in lead II. the results of this study are implemented so that in the future an ECG examination can be carried out and then monitored remotely like a doctor's room because the data communication uses bluetooth.

Abstract

Spectrophotometers generally use a halogen lamp as a light source that passes through a filter (wavelength) according to the material to be analyzed. This study aims to analyze the ability of the LED as a light source on a spectrophotometer. In this study, the authors have determined blood sugar parameters as the test material. So that the determination of the wavelength of the LED as a light source must be adjusted to the specifications of the wavelength in the reagent manual procedure used. In the BAV Greiner Glucose Reagent procedure, the allowable wavelength is between 500 - 570 nm with a cuvette thickness of 1 cm. Measured against the reagent blank by the endpoint method. From this reference, the author uses an LED light source with a wavelength of 530 nm, Epistar brand green. The module in this study consisted of a 530 nm LED lamp as a light source, then a lens was added to focus the light beam from the 530 nm LED. The author also adds a Slit / Aperture or it can be called a small hole so that the light passing through is focused at one point of the circle and is passed to the cuvette. The results of the absorption of light will be received by the light sensor (photoresistor) and the data is processed by Arduino and the results are displayed on the display. From the results of this study, the value ranges error from 1% to 3% when a comparative test is carried out with the Analyticon type Biolyzer100 spectrophotometer with 6 different samples and is repeated 5 times each. From these data, it is found that the LED with a wavelength of 530 nm is effective as a light source for checking blood sugar.

Abstract

Termometer digital dikalibrasi menggunakan media. Ada beragam media untuk mengkalibrasi termometer. Dua diantaranya adalah dry block dan media air. Dry block merupakan suatu media kalibrasi suhu pada keadaan kering atau pada lubang yang berudara. Media air adalah media kalibrasi suhu pada keadaan basah atau menggunakan media yang berisi air. Setiap media menghasilkan tingkat kesalahan, koreksi dan ketidakpastian yang berbeda-beda. Begitu pula pada sensor yang digunakan oleh termometer digital. Cara kerja alat ini yaitu dengan memasukkan termometer untuk dikalibrasi ke dalam lubang yang telah disediakan dan akan dibandingkan dengan pembacaan suhu LM35 yang sudah muncul pada display LCD sehingga akan terlihat perbedaan antara pembacaan suhu dari termometer digital dan dari display LCD. Modul suhu ini telah dibandingkan dengan termometer yang telah dikalibrasi di BPFK Surabaya, dan mendapatkan kesalahan terbesar 1,5% dan kesalahan terkecil 0,3%. Dari hasil yang didapat dapat disimpulkan bahwa perbedaan kesalahan pembacaan suhu karena peletakkan sensor dapat mempengaruh terhadap selisih error yang di dapat. Digital thermometers are calibrated using media. There are various media to calibrate the thermometer. Two responses are dry block and water media. Dry block is a temperature calibration medium on a dry surface or in a hollow hole. Air media is a temperature calibration media in wet conditions or uses media that contains air.

Abstract

Water bath is a laboratory equipment that contains water or special liquid that can maintain the temperature under certain conditions during the specified time interval. For this reason, calibration is needed so that the temperature in the chamber waterbath is stable or not. calibration is carried out by comparing measuring instruments and measuring materials to be calibrated to traceable standards that are traceable to national and / or international standards. Based on the results of the identification of the problems mentioned above, the author makes a waterbath calibrator entitled "Waterbath Calibrator (9 channel)" which is very practical, and easy to operate. .This calibration tool uses a K type thermocouple sensor and also the output is displayed to the character LCD to make it easier for users to retrieve data, the reason for choosing a thermocouple sensor is because the error rate is +/- 1,1C while the LM35 is +/- 1,4C. The thermocouple temperature sensor can detect the chamber temperature quite well where the biggest error is obtained with a comparator of 2%, and the lowest error is 0%.

Abstract

Some of the problems faced by partners include the EKG machine in the publich health center (Puskesmas) at the Puskesmas Deket, Lamongan, which has a fairly high workload on daily use, considering that the population in the working area of ​​the Deket Health Center is 44,193 people, so maintenance is mandatory to be carried out regularly to maintain sustainability. the function of the tool on the other side of the Deket, Lamongan health center there are no special personnel or technicians who carry out routine and periodic maintenance of the ECG machine. Therefore, community service activities in the form of counseling and assistance for health workers at the Deket Health Center, Lamongan are important so that they can carry out ECG machine maintenance activities independently. Furthermore, for the last 5 years or so, health workers at the Deket Health Center, Lamongan have received less training or workshops related to the maintenance of the ECG machine. As a completion step, it is necessary to carry out implementation steps through methods, namely communicating with the head of the Deket Health Center, Lamongan Regency to prepare for the right day and target participants to receive ECG maintenance counseling activities at partners, provide counseling for health workers or the person in charge ECG so the next step is to carry out maintenance activities together. With the method we propose, partners can learn together in implementing the SOPs that have been delivered during the counseling. Furthermore, lecturers and students regularly provide assistance for partners in carrying out maintenance activities for 7 months so that partners are expected to carry out maintenance activities independently. The results obtained after carrying out community service activities are ECG machine operators can use the machine well. Several problems related to the irregular display of the ECG recording can be resolved properly, after replacing the ECG electrode cable section. Maintenance of electromedical equipment, especially ECG is important to be done regularly so that the ECG machine can be operated at any time.
