Gizi yang kurang pada remaja putri dapat mempengaruhi pematangan seksual, pertumbuhan, fungsi organ tubuh dan akan menyebabkan terganggunya fungsi reproduksi. Asupan gizi yang tidak adekuat menyebabkan ketidakteraturan menstruasi pada kebanyakan remaja putri serta gizi yang adekuat pada remaja adalah gizi yang bervariasi dan seimbang. Tujuan: untuk mengetahui adanya hubungan status gizi dengan siklus menstruasi pada remaja putri. Metode penelitian: adalah analitic survey dengan menggunakan metode pendekatan croossectional. Populasi dalam penelitian adalah seluruh remaja putri berjumlah 126 orang dengan teknik sampling adalah total samping. Instrument yang digunakan dalam penelitian adalah kuesioner. Penelitian ini dilaksanakan di Madrasah Aliyah (MA) DDI Kanang Kabupaten Polewali Mandar Tahun 2019. Hasil: penelitian mengungkapkan sebanyak 77 responden (61,1%) dan yang memilki siklus menstruasi normal sebanyak 101 responden (80,2%). Hasil penelitian Menggunakan uji Chi Square didapatkan nilai ρ 0,00 < 0,05. Rekomendasi: bahwa terdapat hubungan antara status gizi dengan siklus menstruasi pada remaaja putri di MA DDI Kanang Polewali Mandar. Oleh karena itu diharapkan tenaga kesehatan memperbanyak penyuluhan tentang kesehatan khususnya bagi remaja putri tentang pentingnya nutrisi yang seimbang terhadap keseimbangan metabolisme tubuh yang berdampak pada siklus menstruasi pada setiap bulannya.

“…Furthermore, Ni Nyoman Sri Malini also made an ECG Simulator device in 2017 using the formation of an ECG signal with a 4017 IC counter and a NE555 clock. Unlike the DAC IC which can be formed by plotting the original image of the heart signal, the 4017 IC counter has a weakness in the use of capacitors, causing an imperfect ECG waveform in the ST segment and the large capacitor value affects the segment width and interval on the PQRST wave [16]. In this case, the ECG Simulator has a BPM range of 30 -240.…”

Electrocardiograph (ECG) is one of the diagnostic sciences that is often studied in modern medicine, used to detect damage to the components of the heart or disorders of the heart rhythm called arrhythmias. The purpose of this research is to develop an Electrocardiograph simulator that is equipped with arrhythmia. The main design consists of an Arduino Mega 2560 microcontroller, MCP4921 DAC (Digital to Analog Converter) circuit, a network resistor, and a sensitivity selection circuit. The MCP4921 type DAC converts the digital signal data into analog data which will then be forwarded to the resistor network circuit as a signal formation for each lead. The basic signal image data used for the formation of normal Electrocardiograph and arrhythmias were taken from the Electrocardiograph recorder using Phantom Electrocardiograph. Based on the readings on the Beat Per Minute setting of the module to the Beat Per Minute printout on the Electrocardiograph recorder, the error rate value for the Normal Sine Rhythm parameter is 0.790% for Beat Per Minute 30, 0.383% for Beat Per Minute 60, 0.535% for Beat Per Minute 120, 0.515% for Beat Per Minute 180 and 0.593% for Beat Per Minute 240. The error rate for the Arrhythmia parameter is 2.076% for ventricular tachycardia Beat Per Minute 160 and 0.494% for Supraventricular Tachycardia Beat Per Minute 200. The design of the Electrocardiograph simulator can simulate the signals of the human body and it can be used as a medium in the learning process in the world of health

“…This tool is equipped with a sensitivity selection selector and BPM and uses the method of forming a heart signal through the MCP 4921 type DAC. [6] Based on the identification of the research above, the author intends to design a phantom ECG. Where this tool is equipped with sensitivity selection, beats per minute (BPM) and uses a digital to analog converter type MCP4921 as a heart signal formation.…”

Electrocardiograph (ECG) is one of the diagnostic sciences that is often studied in modern medicine, one of which is to diagnose and treat diseases caused by the heart. Therefore, it is necessary to check the function of the ECG recorder tool, namely by carrying out the tool calibration procedure using Phantom ECG. The purpose of this research is to design a Phantom ECG for a 12 channel ECG device which includes lead I, lead II, lead III, aVR, aVL, aVF, V1, V2, V3, V4, V5, and V6 and completes it with a sensitivity selector. The contribution of this research is that the tool can be used as a calibration tool for the ECG Recorder and can be used as a learning medium in the world of health. In order to create a signal that matches the original, this tool uses a heart signal formation method using a DAC type MCP4921 with an ATMEGA2560 microcontroller and for display settings using a 2.4 inch TFT Nextion Display. The MCP4921 type DAC converts the digital signal data into analog data which will then be forwarded to the resistor network circuit as a signal formation for each lead. In the measurement results, the error in measurements with sensitivity of 0.5 mV, 1.0 mV, and 2.0 mV using an ECG Recorder at BPM 30 is 0.00%, BPM 60 is 0.00%, BPM 120 is 0.00%, and BPM 180 is 0.56%. The results showed that the biggest error was found in BPM 180, which was 0.56%.
