Abstract

Laboratorium merupakan tempat yang dilengkapi dengan berbagai instrumen, peralatan dan bahan kimia (reagen), kegiatan yang dilakukan pada laboratorium meliputi karya eksperimental, kegiatan penelitian dan prosedur pemeriksaan. Water bath merupakan suatu alat yang digunakan pada laboratorium kesehatan untuk melaksanakan kegiatan serologi, aglutinasi, inaktivasi, biomedis, terfarmasi dan prosedur inkubasi industri. Fungsi utama Water bath adalah membuat suhu yang konstan dengan waktu yang sudah ditentukan. Maka, penelitian ini akan merancang alat water bath dilengkapi dengan sensor ketinggian air dengan menggunakan komponen pendukung berupa Arduino Mega 2560, sensor DS18B20, keypad 4x4, driver relay, heater, driver water level dan LCD 20x4. Metode penelitian yang digunakan dalam pengujian ini dengan menguji suhu pada wadah dengan mengukur suhu pada wadah alat. Jika kinerja alat sudah sesuai atau suhu yang diuji dengan menggunakan sensor DS18B20 tidak berbeda jauh dengan alat pembanding, maka alat sudah bekerja dengan baik dan jika hasil yang ditampilkan kurang baik, artinya suhu pada wadah tidak tersebar dengan merata sehingga suhu pada wadah tidak sesuai dengan pengaturan suhu. Kesimpulan dari penelitian ini yaitu Wadah memiliki pemansan yang maksimal disuhu 37°C - 50°C. Nilai Error terendah pada pengujian pembacaan sensor suhu adalah 0,20% pada suhu 50°C dan terbesar 1,11% pada pengujian suhu 45°C. Nilai Error terendah pada pengujian alat adalah 1,77% pada suhu 44°C dan terbesar yaitu 3,66% pada pengujian suhu 47°C.

Abstract

The use of medical equipment in the world of health is very much needed, one of which is an electrostimulator which can be used to help recovery in post-stroke patients. Electrostimulators can be made with several conditions, namely: controller, stimulator, and electrodes. Apart from that, there are 4 parameters needed for the electrostimulator, namely 1) Pulse Amplitude, 2) Pulse Width, 3) Pulse Shape, 4) Pulse Frequency. In this electrostimulator, it is highly recommended to use a surface electrode, apart from being a non-invasive electrode, this electrode also provides comfort and is easy to use. Judging from this, an innovation was carried out, namely making an electrostimulator with the choice of 2 modes, namely continuous and intermittent. The research procedure was carried out in several stages starting from preparing tools and materials, measurements and functional tests. The results of the research are a design for an electrostimulator therapy device with a power supply connected to a microcontroller and displayed on an LCD. The test results showed that the error percentage at the power supply input was 5.9%, the power supply output was 3%, and the buzzer output was 0%. The results of testing and analysis of the tool on the oscilloscope showed that the error percentage at frequency values of 2 Hz, 4 Hz, 5 Hz, 7 Hz and 8 Hz was 0.05%, 0%, 2%, 4% and 8% respectively. Based on the results of this research, it can be concluded that the tool is as desired and good to use.

Abstract

Telemonitoring is a method of long-distance health services using information technology to provide data to health services. Telemonitoring can save time, costs and effectiveness of health services. The biggest challenge in using Telemonitoring is that the adoption rate is still low and there has not been much development in medical equipment. Pulse Oximeter Using Nellcor SpO2 Based on the Internet of Things, functions to measure oxygen saturation (SpO2) and measure heart rate remotely. Then the results can be monitored via an Android smartphone application by utilizing an internet connection. To make this happen, hardware and software planning was made. This module uses a Nellcor SpO2 sensor which will regulate SpO2 and Heart Rate values ​​in the range of 60-100%. This microcontroller module uses ESP32 which will act as the brain of the device controller and connect the device to an Android smartphone. The measurement results of this tool are tampilaned on a 3.5 inch Nextion LCD and the Inventor application on an Android smartphone. The difference between oxygen saturation and heart rate readings on the Prosim 8 device has the largest error percentage of 5.4% for heart rate and the smallest at 0% for SpO2. This application can record SPO2 data and falling heart rate on patients periodically, so that their condition and condition can be monitored. for diagnostic data on patients remotely.
