PENGUKURAN DIMENSI LUAR, DALAM SERTA TEBAL RELATIF DIVAIS ELEKTRONIK MEMORI USB MENGGUNAKAN CITRA RADIOGRAFI

ABSTRACT: Radiographic imaging has been done for profile aluminium with arrange in steps and 5 USB memory to measure the dimension inner and outer part of 5 USB memory without destroying it. Based on this image, the function of characterization for relative thickness of aluminium's profile with grayscale level is gained. With characteristic mentioned before the dimension and relative thickness of profile memory USB is determined. The result are the dimension outer part of profile that consist of the length is 31–57 pixel, the width is 13–22 pixel and the wide is 465–1197 pixel2, later the dimension inner part of profile that consist of the length is 28–30 pixel, the width is 10–16 pixel and the wide is 300–480 pixel2 and the last, the relative thickness of electronics device is range from 3,36–7,62 mm.
