Abstract

Image quality is an important parameter in object detection. Image with good quality will produce high accuracy in the object detection process. Image quality is measured using the peak signal comparison of the original image with the interference that occurs in the image. This comparison is formulated with the Peak Signal To Noise Ratio (PSNR). PSNR values obtained from variations in image quality improvements will be seen in its characteristics in object detection methods using the Viola Jones method. The higher PSNR value will definitely produce better accuracy, but improving the image to the best quality will drain resources and a high computational burden so it needs to find a minimum PSNR value that can still be considered good in the object detection process. The minimum PSNR value for the image is said to be feasible to be processed 19.05 dB. The minimum PSNR value before the object can no longer be detected is 12.43 dB.

Abstract

Welding technique is one of the process connection metal in the manufacturing industry. Aluminum alloys have several advantages including: light, good electrical and corrosion resistant properties. Welding application of  dissimilar aluminum alloys with the  5083 and 6061-T6 series such as building structures, bridges, railroad frames, ships and oil platforms. The joining of dissimilar aluminum alloys by welding technique is difficult because the metal has different thermophysis properties. The study aimed of this research to analyze the mechanical properties of variation welding current on joint area GTAW. Visual observation shows that the joint specimen with the low current (100 A) has low penetration in welding groove, whereas at the high current (140 A) undercut occurs on the side of the weld seam, there are spatter and deposits (excessive added material). The hardness test with the current 120 A shows the regular distribution and has the highest tensile test of 201 MPa.
