Abstract

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%.

Abstract

Masa anak balita merupakan kelompok yang rentan mengalami kurang gizi salah satunya adalah stunting. Stunting menggambarkan status gizi kurang yang bersifat kronik pada masa pertumbuhan dan perkembangan sejak awal kehidupan. Masalah gizi terutama stunting pada balita dapat menghambat perkembangan anak. Tujuan penelitian ini adalah merancang alat ukur berat dan tinggi badan dilengkapi penilaian status gizi balita, tujuan menentukan penilaian status gizi adalah apabila terjadi penyimpangan status gizi pada balita dapat segera diberi tindakan agar kondisi balita tidak memburuk. Kontribusi penelitian ini adalah mengukur berat dan tinggi badan balita, dari data berat dan tinggi badan tersebut dapat diketahui status gizi pada balita. Agar dapat mengetahui penilaian status gizi balita, dasar utama dalam penelitian ini menggunakan metode Antropometri. Penulis ingin membuat sebuah modul yang digunakan untuk melakukan pengukuran pada balita dengan parameter tinggi badan. Dalam perancangannya, modul ini menggunakan Arduino sebagai pengontrol utama. Sensor yang digunakan adalah variabel resistor (potensiometer) yang berfungsi untuk mendeteksi tinggi badan balita lalu dikirim oleh modul bluetooth HC-05 ke PC untuk dilakukan pembacaan dan hasilnya ditampilan dalam bentuk penilaian status gizi. Berdasarkan hasil pengukuran tinggi badan balita pada modul diperoleh error maksimal sebesar 0.35 % dan rata-rata errornya sebesar 0.093%. Alat ini dapat diimplementasikan pada pemantauan pertumbuhan berat dan tinggi balita.

Abstract

In using the Electrosurgery unit, improper power settings and modes can cause tissue damage, so it is necessary to adjust the cutting mode and power settings needed. The purpose of this research is to design power control and cutting mode in Electrosurgery using Arduino nano as a regulator of power and pulse or duty cycle. The contribution of this research is the creation of power control and mode in the Electrosurgery unit to increase power and cutting mode. This is to control the electrosurgery power. The LM2907 IC frequency to voltage circuit is used as a voltage regulator, which is issued according to the frequency with the power selection LOW, MEDIUM, HIGH. The method used is the CMOS 4069 device as a frequency generator at 250 kHz, then the driver pulse is passed and controlled by the ATmega328 IC, then forwarded to an inverter circuit that functions to increase the voltage and output in the form of power. After the measurement process is carried out on the inverter input with a Blend mode three value, the voltage value is obtained at the low setting 100 V error 0.03%, medium setting 110V error 0.02%, High setting 120 V Error -0.02%. While the measurement results in the coagulation mode are the low setting error of 100 V 0.05%, the medium setting error is 110V 0.08%. High setting error is 130 V 0.003%. The measurements show that the error in power management is lower than 1%. The results of this study can be implemented in the electrosurgery unit to reduce tissue damage due to a lack of cutting modes and power management.

Abstract

"Wearing High Heel, Face Smiling, Heart Screaming", that's the headlines of one women'smagazine in Indonesia. Shoes are one of which had a role in the activity of a woman.Shoes have health function and aesthetics. Several studies have reported that theproportion of the prevalence of foot problems in women is associatedwith the use of high heels.One of the health problems caused by high heels is osteoarthritis. Symptoms include pain andstiffness in muscles and joints of bones. In the lower stage, a complaint can be treated withmedication and exercise movement. In later stages require surgery replacement cushions joints. Basedon the effects of the joints and muscles of the foot, the research about the use of high-heeled shoesnecessary.This study uses the FFT method that generates the frequency spectrum of the EI\1G signal on thegastrocnemius muscle and soleus muscle. The results of the frequency spectrum of thesignal provided an information about the content of the signal frequency form. Afterobtained the spectrum of the signal is, then it's calculated Mean Power Frequency(MPF).In this study, MPFvalue on the soleus muscle produced the 100-200 Hz frequency, the gastrocnemiusmuscleshowed a lower frequency than the soleus muscle 60-80 Hz frequency. The use of high heels7 Cm affect the soleus muscle increasing in the frequency ofthe initial frequency of 100-120 cm be180-200 Hz frequency. The use of high shoes with different rights can be classified clearly in the soleusmuscle MPF.It shows that the soleus muscle a major effect on height heel imposed on respondents. Theuse of high heels from 3 cm to 7 cm does not change the frequency of gastrocnemius muscle.Frequencyare still remain 60-80 Hz.KEYWORDS: Signals, Frequency, Muscles, Shoes
