“…Because of the different types of apparatus and methodology, the prediction of BIA varies by 10% of body weight. The different estimated equations with their variables are developed based on the method used as a reference [28]. The device used in [29] has multilead or multielectrodes for accurate measurement.…”

The present research aims to measure the segmental bioelectrical impedance (BI) of the human body at multifrequency, using a server user interface-based prototype, which provides subjects with measured data online anywhere accessed by their unique identifications. The present research measures the BI of the human leg and arm at a multifrequency range of 50–400 kHz with a developed and standard device. Recorded data can be transferred to the subject using Wi-Fi technology with their unique identifications and password. The system uses Wi-Fi interfacing for real-time data measurement and online data storage. The prototype can be used commercially. The compact size of the prototype becomes the demand of the common population. The pocket carry size makes it easy to carry anywhere for regular monitoring of the human body to prevent critical disease. The resultant data show that the mean and standard deviation of the left and right leg are 282.2 ± 14.29 and 274.80 ± 13.91 Ω, respectively. Similarly, in the case of the left arm and right arm, the mean and standard deviation are 325.41 ± 16.54 and 320.73 ± 16.07 Ω, respectively. The relative error between developed and standard devices is 3.53%. Results show that the left leg and arm impedance is always greater. However, the right leg and arm muscles are stronger than the left one, with less impedance at all frequencies.

“…Rumus FFM diperoleh sesuai dengan Persamaan 1 berikut adalah tinggi tubuh (dalam cm), R adalah impedansi tubuh (dalam Ohm), w adalah berat tubuh (dalam kg) dan a adalah umur (dalam tahun). Setelah didapatkan nilai FFM maka didapat nilai massa lemak (fat mass -FM) dan BF dengan Persamaan 2 dan 3[11]: sinyal bermula dari pengukuran tegangan dari dua elektroda, dimana arus bolakbalik berfrekuensi tertentu dialirkan di antara kedua elektroda tersebut. Karena tegangan yang terukur kecil (dalam orde millivolt), maka diperlukan rangkaian berikut: a. Instrumentation Amplifier Instrumentation Amplifier adalah sebuah jenis penguat diferensial yang telah dilengkapi dengan buffer, sehingga menghilangkan kebutuhan untuk pencocokan impedansi masukan.…”

Timbangan badan biasa tidak dapat membedakan antara massa lemak dan massa non lemak. Oleh karena itu, dibutuhkan suatu alat pengukuran yang mampu membedakan massa lemak dan massa non lemak. Untuk mengetahui komposisi tubuh, digunakan metode Bioelectrical Impedance Analysis (BIA) yang memiliki keunggulan yaitu murah, mudah, dan portable. Penggunaan frekuensi yang berbeda pada BIA memberi kelebihan pada kemampuan segmentasi. Untuk itu, pada penelitian ini, dilakukan rancang bangun BIA yang bekerja pada beberapa frekuensi berbeda, yaitu Multi Frequency Bioelectrical Impedance Analysis (MFBIA). Sistem pengolahan sinyal BIA dirancang berbasis ARMSTM32F103C8T6. Hasil penelitian menunjukkan bahwa sistem pengolah sinyal dapat menghasilkan data persentase lemak tubuh. Galat relatif dari sistem pengolah sinyal sebesar 9,926% pada metode Hand-to-Hand, dibandingkan terhadap alat pembanding komersial sejenis.
