Abstract

pH Meter is a device used to express the level of acidity or basicity possessed by a substance or solution. Normal pH has a value of 7 while the pH value> 7 indicates that the substance has alkaline properties while the pH value <7 indicates acidic properties. pH 0 shows a high degree of acidity, and pH 14 shows the highest degree of alkalinity. pH Meter reads the pH and temperature values ​​in a sample. The author uses glass electrodes as a pH sensor, DS18B20 as a temperature sensor and LCD to make pH and temperature values. This module is equipped with an internal calibration that is used to set the module to read the pH value properly and correctly using a pH buffer and equipped with internal storage and this module facilitates battery usage. Based on pH measurements on the module the error value in buffer 4 calibration is 5.39%, in buffer 7 is 1.76%, in buffer 10 is 1.04%. The highest error value in the measurement sample is 3.54% and the lowest error value is 0.03%. The temperature of the sample is very influential on the reading of the pH value because the higher the temperature the pH value also increases even though it is not so significant.

Abstract

Waterbath is a device used to create a constant temperature. This tool is used to incubates in microbiology analysis. Temperature is maintained according to the desired range. The heating element is controlled by the heater driver. This module is created by using Arduino Atmega 328 as a minimum system and time controller, Using a PID controller as temperature control, and using a DS18B20 sensor as a temperature sensor. The design of this study uses pre-experimental methods after only design research. The measurement results are done by comparing the module with a standard measurement instrument that produces the biggest % error in setting temperature of 37 ˚C which is equal to 1.21%, it is related to the boundary between water temperature and temperature setting too short which is affected by the DS18B20 temperature sensor reader that need time, to get a stable temperature reading. The minimum % error located at 60 ˚C, because to reach the temperature setting needs a long time so that DS18B20 the sensor reading is stable of setting temperature which is equal to 0.11%. The value % error of the timer is 3.4 % which the amount of the error is affected by the number of DS18B20 which is used and the delay from the microcontroller. Based on the results obtained this module can be used properly because still on the maximum limit error value less than 5%.

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

Waterbath merupakan peralatan laboratorium yang digunakan untuk inkubasi sampel melalui media air atau cairan khusus yang bisa mempertahankan suhu pada kondisi tertentu selama selang waktu yang ditentukan. Untuk memakasimalkan kinerja waterbath, perlu adanya indikator deteksi level air sebagai pengaman volume air agar heater tidak sampai rusak dan safety control yang bertujuan agar suhu di dalam waterbath tidak melebihi suhu yang telah ditetapkan serta adanya sistem monitor suhu yang digunakan untuk memastikan bahwa suhu terdistribusi secara merata. Modul ini menggunakan thermostat dan level air sebagai safety control. Sensor level air digunakan sebagai deteksi level air dengan indikator LED. Penulis menggunakan microcontroller arduino uno sebagai pengendali sistem safety heater berupa level air serta monitor distribusi suhu. Hasil data pengukuran suhu waterbath didadapatkan nilai error paling besar pada titik 1 sebesar 1,51% pada suhu 37˚C, pada titik 2 sebesar 1,36% pada suhu 37˚C, pada titik 3 sebesar 1,12% pada suhu 37˚C, pada titik 4 sebesar 1,81% pada suhu 37˚C. Nilai tersebut masih di bawah batas toleransi error sebesar 5%. Nilai error terendah pada setiap titik sensor adalah saat suhu setting 60˚C. Hal itu dikarenakan waktu yang dibutuhkan untuk mencapai suhu setting lama sehingga pembacaan sensor suhu DS18B20 semakin konstant dan tepat.

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.
