HERU PRIYONO ABSTRACT
SOUND FREQUENCY INVESTIGATION OF TIRE DETECTION FAILURE IN TRUCK AND BUS RADIAL TIRE USING DRUM TEST MACHINE

SWISS GERMAN UNIVERSITY
Indoor test on the tire using the drum test machine by applying pressure and rotation according to the test method that has been determined until the tire is damaged, even until the tire explodes. This is done by measuring the maximum strength of the tire.
Damage or explosion on the tire when testing takes place is not expected to occur, because this explosion can damage the drum test machine. For research and development purposes it is necessary to find out the location of the initial damage to the tire so that it can be improve on the weak part of the tire. A few moments before the tire is damaged a lump on the tire occurs and produces an unusual sound. This change in the frequency of sound that occurs before and when the initial tire is damaged will be analyzed, which will then be used to create a tire damage detection system so that the test can be stopped when the tire has initial damage.
Keywords: Indoor Test, Drum Test, Sound Frequency, FFT, Frequency Analysis.

HERU PRIYONO DEDICATION
I dedicate this thesis for my family who always supports me, my thesis advisor and all of my friend’s who has been my inspiration and support me to finish this research.
HERU PRIYONO ACKNOWLEDGMENT
I wish to thank the members of my committee for their support, patience and good humor. Their gentle but firm direction has been most appreciated. Dr. Ir. Widi Setiawan was particularly helpful in guiding me toward a qualitative methodology. Dr. Ary Syahriar interest in sense of competence was the impetus for my proposal. Finally, I would like to thank Dr. Ir. Gembong Baskoro, M.Sc. From the beginning, he had confidence in my abilities to not only complete a degree but to complete it with excellence.
I have found my coursework throughout the Curriculum and Instruction program to be stimulating and thoughtful, providing me with the tools with which to explore both past and present ideas and issues.
I would like to thank all of my friends from a Master of Mechanical Engineering Batch 5 that have given me a viewpoint and become my partner in discussion.
I would like to thank all of my colleagues at PT GT for their support and understanding during my research.
