Abstract

Osteoporosis is defined by a decrease in bone mass and a deterioration in bone microstructure. It is a major public health issue and a significant economic burden for both individuals and society. Thus, monitoring bone mass and structure is necessary to prevent bone fragility and osteoporosis. This study aimed to develop a prototype of quantitative ultrasound (QUS) and to evaluate the feasibility of backscatter mode for the bone assessment. Ultrasound (US) signals that propagate through the bone can be characterized by comparing the signal from both transmitter and receiver transducers. The US backscattered signal depends on the characteristic of both medium and transducer. In this study, we analyzed the attenuated signal based on the parameters: type of bone (compact and spongy), type of coupling medium (air, starch, and gel), the angle between transducers and bone (30o, 60o, and 90o), and transducer distance (0, 10, 5, 15, 20 and 25 cm). We use only 1 MHz transducer frequency. The prototype has been evaluated by Digital Oscilloscope and LabVIEW user interface to observe received signals. The results of this study showed that there was a difference in amplitude of the US signal from compact and spongy bones. The amplitude is directly proportional to acoustic impedance and inversely proportional to the distance between transducers. There is a negative correlation between bone microstructure to attenuation, and compact bones have a greater attenuation coefficient than spongy bones.

Telah dilakukan pembuatan alat dengan menggunakan metoda "EM survei geofisika" dalam bentuk sensor fluxgate, sensor potensial listrik, dan unit injector flow. Elemen sensor "fluxgate" dibentuk dengan menggunakan kumparan sekunder ganda. konfigurasi elemen sensor "fluxgate" terdiri dari variasi lilitan primer 4 x 40 dan lilitan sekunder 2 x 60. Kumparan primer akan membangkitkan sebuah medan magnet internal yang berfungsi sebagai medan magnet acuan ketika kumparan sekunder digunakan untuk mengukur medan magnet eksternal (mendeteksi) sehingga sensitivitas sensor fluxgate ditentukan dengan bentuk kumparan sekunder. Berdasarkan analisa data, diperoleh sensitivitas sebesar 283.02 mV/mT dan dapat mendeteksi medan magnet hingga 3:53 nT. Sebuah sensor potensial listrik memiliki rentang pengukuran  yang diperoleh dari masukkan sensor sebesar 0-13 mV dan menghasilkan tegangan keluaran 0-5 volt. Ketika keluaran dari IGBT yang berfungsi sebagai saklar dan belum diatur menggunakan  unit antarmuka, dapat menghasilkan 50% siklus sinyal yang cukup baik, sehingga masih diperlukan perbaikan pada unit interface circuit flow transmitter. The research done supporting the manufacture of devices based on the method of EM geophysical survey in the form of fluxgate magnetic sensors, electric potential sensors, and interface unit injector flow. Fluxgate sensor element designed using a secondary coil (pick-up) double. The composition of fluxgate sensor element consists of two primary coils (excitation coil(4x40), two secondary coils (2x60). Primary coil will generate an internal magnetic field that serves as a reference magnetic field while the secondary coil serves to measure the external magnetic field (sensing) so that the sensitivity of fluxgate sensor is determined by the secondary coil design. Based on analysis of data obtained sensitivity 283.02 mV/mT, and can detect magnetic fields up to 3:53 nT. An electric potential sensor have a range of measurements obtained by sensor inputs 0-13 mV and produces a voltage output 0-5 volts. While the output of the IGBT which functions as a switch and have not be set using the interface unit can generate 50% duty cycle signal that is good enough, so it is still need for improvement in the unit interface circuit flow transmitter.

Abstract

Screen Mesh is a filter made of wire that serves to remove the fine vortex structure by equating the speed variation of wind flow in the wind tunnel. Adding the screen mesh is to determine the effect of screen mesh to the value of turbulence intensity on open circuit wind tunnel. In this study, it has been made three pieces of screen mesh with each diameter of 46.5 cm, 48.5 cm and 50.5 cm. The tests was carried out by using screen mesh with rhombic mesh with 3 mm diagonal length that placed on X/L 0.67, 0.8, and 0.93. This research was conducted by comparing the results of turbulence intensity measurements between the wind tunnel without screen mesh, wind tunnel with honeycomb and screen mesh, as well as wind tunnel with only screen mesh so that we can know the flow quality in the wind tunnel. The test results indicated that the screen mesh has the ability to minimize the turbulence intensity. The wind tunnel that is installed using a honeycomb cell has 6 mm diameter and the 3 pieces of screen mesh has the lowest turbulence intensity that is I ≈ 0,0242. Keywords: wind tunnel, screen mesh, turbulence intensity.
