<![CDATA[An issue that arises in the hand motion classification based on the electromyography (EMG) system is the failure of choosing the right features and number of muscles. These parameters are fundamental in determining the accuracy and effectiveness of the classifier system. Therefore, the objective of this study is to develop and evaluate an effective hand motion classifier based on the EMG signal. The three-channel of EMG was collected by placing three pairs of electrodes on the surface of the skin. Six statistic features (mean, variance, standard deviation, kurtosis, skewness, and entropy) were selected to extract the EMG signal using a window length of 100 samples. A muscle and features selection is applied to the classifier machine (linear discriminant analysis (LDA), support vector machine (SVM) and K nearest neighborhood (KNN)) to retrieve the most useful feature and muscle. In this study, we found that there was no significant difference in accuracy among a number of muscles (p-value>0.05). LDA and SVM showed the best accuracy and no significant difference in accuracy between both were found. This study concluded that EMG signal from a single muscle can classify the hand motion (hand close, open, wrist flexion, and extension) effectively. ]]>

<![CDATA[Electrosurgery Unit is a medical device that utilizes high frequency and voltage used to cut and dry tissue during the surgical process. The purpose of making this tool is to damage certain body tissues by heating the tissue. Heat is obtained by concentrating high frequency electricity on certain body tissues using active and passive electrodes as a medium. The Electrosurgery Unit involves the use of the CMOS 4069 IC as a frequency generator. The output frequency is set at 300 KHz then forwarded to the pulse regulating circuit and controlled with ic atmega328 then forwarded to the inverter circuit which functions to increase the voltage and output in the form of power. The module is calibrated using ESU Analyzer. This module is equipped with LOW, MEDIUM, HIGH. After the measurements are made, the more load is given higher to the tool, the higher the power released by the tool in each power selection. Then the load relationship and the power released are directly proportional. This ESU was made so that during the surgical process the body's tissue does not experience a lot of blood loss. Besides being able to use it for surgery, it can also be used to close the tissue after surgery.]]>

<![CDATA[Pulse oximeter is a tool to monitor oxygen saturation in the blood (arteries) and also a person's heart rate (BPM) without having to go through blood analysis. Lack or excess of oxygen in the blood will cause illness and disruption of the body's work. At a certain level, this disease can cause the risk of death. The purpose of this study was to develop a pulse oximeter. The design of this equipment uses the MAX30102 sensor. Then the sensor will start working and Arduino will do data processing. Data from the MAX30102 sensor entering the I2C pin is then displayed on the TFT LCD screen. This equipment is made portable to make it easier for users to do monitoring anytime and anywhere.This test is done by comparing modules with standard measuring instruments. From the results obtained, this equipment is worthy of use because by "Pedoman Pengujian dan Kalibrasi Alat Kesehatan” DEPKES RI tahun 2001, the maximum limit in fault tolerance was Pulse Oximeter ± 1%.]]>

<![CDATA[The calibration process aims to guarantee that a measurement device is to follow the established standards. The purpose of this study is to design an automatic leak test for digital pressure meter in which the function of this device is to measure pressure on the sphygmomanometer and suction pump or other devices that use pressure parameters for measurement. This study used the Arduino as a control system, and to process the analog data into digital. Signal conditioning, based on the amplifier circuit, was also applied for the MPX5050GP and MPXV4115VC6U sensor. The proposed design used a 4x20 liquid crystal display to show the parameters in this design ware also equipped with a selector of mmHg or kPa units. The result shows that the fluctuating resolution is 0.25 mmHg. In this design, an automatic leak feature was also equipped for the sphygmomanometer. The results obtained an average error of 7.3 mmHg for sphygmomanometers. On the other hand, the suction pumps have an accuracy of less than 1.5 kPa. From these results, it was concluded that this design could be used for the measurement of devices that use positive pressure and negative pressure]]>

<![CDATA[In performing the calibration of the sphygmomanometer, the officer needs to first reset the installation and pump the bulb slowly until it reaches the set point in accordance with the calibration settings where this does not provide convenience to the calibration officer. So the author wants to do research on making additional devices to support DPM calibration instruments that have been commercialized to speed up the pump process in Sphygmomanometer calibration. The purpose of this research is to make an Automatic Pump module with PID control to analyze the stability of the pressure achievement in accordance with the set point when using the smoothing program or not. This study used set points of 50, 100, 150, 200, and 250 mmHg. Data retrieval was carried out within 260 seconds at each set point at the Campus of the Department of Electrical Engineering Poltekkes Kemenkes Surabaya. The results of this study indicate that the tool testing using the smoothing program experienced small oscillations compared to the program without smoothing. The data obtained are at setting 50 the average overshoot is 54 and the average undershoot is 49; at setting 100 the average overshoot is 109 and the average undershoot is 99; at setting 150 the average overshoot is 156 and the average undershoot is 149; at setting 200 the average overshoot is 206 and the average undershoot is 196; at setting 250 the average overshoot is 253 and the average undershoot is 247. The importance of this device was made in order to make it easier and faster for the calibration officer to calibrate the Sphygmomanometer.]]>

<![CDATA[Penyakit Paru Obstruktif Kronik (PPOK) adalah penyakit obtruksi jalan napas karena bronchitis kronik atau emfisema. Salah satu penyebab PPOK adalah merokok. Monitoring saturasi oksigen digunakam untuk mengetahui nilai SPO2 selama satu menit pada perokok pasif maupun aktif yang bertujuan untuk monitoring kondisi Saturasi Oksigen pasien rawat jalan dan jika terjadi nilai yang tidak normal dapat dijadikan sebagai peringatan awal terjadinya risiko dari Pola Hidup Merokok. Tujuan dari penelitian ini membuat alat monitoring SPO2 via Android menggunakan sensor MAX30100. Sensor MAX30100 bekerja berdasarkan penyerapan cahaya IR dan LED yang masuk ke sensor, data dari sensor MAX30100 masuk ke pin 12C pada minimum sistem arduino, kemudian diolah sehingga menghasilkan presentase nilai SPO, yang kemudian ditampilkan pada LCD 16x2 dan Android dengan menggunakan Bluetooth sehagai media pengiriman. Pada peneliti sebelumnya dihasilkan error sebesar 0,6% dan hasil dari penelitian sekarang dengan melakukan pendataan 5 responden dengan 6 kali pengambilan data di dapatkan error sebesar 0.27%.]]>
