Automatic winder is a device that can be controlled using a remote controller which can be operated from a distance. It is equipped with electronic component like battery, raspberry pi and mechanical component such as gear, motor, and drive cable. This device will be used to perform radiographic testing which highly exposed to the gamma radiation. Front surface of the automatic winder is an area that receive high dose rate, thus proper shielding needs to be considered to protect component inside the automatic winder. In this study, two type of shapes were selected to be installed at the front surface of the winder housing. By using Monte Carlo N-Particle, increase the thickness of depleted Uranium from 1 mm, 3 mm, 5 mm, 7mm, 9 mm and 11 mm will reduce the dose rate received to the automatic winder. When comparing the shape, it shows that hemisphere shape gives better shielding compared with rectangular shielding.
